Description
Technical Field
[0001] This utility model relates to a fire extinguisher testing device, specifically to a separation and reflux mechanism for a fire extinguisher fixture. Background Technology
[0002] After inflation, inflatable fire extinguishers require water testing. To improve testing efficiency, the applicant has developed a fire extinguisher water testing device capable of batch testing. Before testing, multiple fire extinguishers are loaded into fixtures. A robotic arm then picks up multiple fixtures at once and places them into a testing tank for testing, enabling batch testing. After testing, the robotic arm removes the fixtures, effectively improving the efficiency of fire extinguisher water testing.
[0003] After the fire extinguisher is tested with water, it needs to be removed from the fixture for drying and other operations. The fixture also needs to be reused at the fire extinguisher installation station. Therefore, a device is needed to separate the fire extinguisher from the fixture. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a separation and return mechanism for fire extinguisher fixtures, which can separate the fire extinguishers one by one from the fixture and return the empty fixtures to the fire extinguisher loading station.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a separation and return mechanism for a fire extinguisher fixture, including a discharge platform, a stepping pusher module, a fire extinguisher conveying module, and a separation module. The discharge platform is provided with a fixture return channel and a separation zone. The stepping pusher module is located on the discharge platform and pushes the fixture to move stepwise along the fixture return channel, causing each fire extinguisher on the fixture to stop sequentially in the separation zone. The separation module then grabs the fire extinguishers in the separation zone and places them onto the fire extinguisher conveying module. The stepping pusher module pushes the fixture on the discharge platform to move stepwise. Each time the fixture stops, one fire extinguisher on the fixture is in the separation zone. The separation module grabs the fire extinguishers in the separation zone and places them onto the fire extinguisher conveying module, thus achieving the separation of the fire extinguishers from the fixture and the return of the fixture.
[0006] As an optional technical solution of this utility model, the separation module includes a telescopic drive component and a bottle-grabbing component. The telescopic part of the telescopic drive component is connected to the bottle-grabbing component. The telescopic drive component drives the bottle-grabbing component to reciprocate between the bottle-grabbing position and the bottle-placing position. The bottle-grabbing position is in the separation zone, and the bottle-placing position is on the fire extinguisher delivery module. When the telescopic drive component drives the bottle-grabbing component to the bottle-grabbing position, the bottle-grabbing component grabs the fire extinguisher in the separation zone. When the telescopic drive component drives the bottle-grabbing component to the bottle-placing position, the bottle-grabbing component places the grabbed fire extinguisher onto the fire extinguisher delivery module. The stepping movement of the fixture and the reciprocating movement of the bottle-grabbing component driven by the telescopic drive component between the bottle-grabbing position and the bottle-placing position separate the fire extinguishers from the fixture.
[0007] As an optional technical solution of this utility model, the bottle gripping component is an electromagnetic adsorption component or a negative pressure adsorption component.
[0008] As an optional technical solution of this utility model, the fire extinguisher conveying module is set outside the discharge platform, and the conveying direction of the fire extinguisher conveying module is parallel to the direction of the jig return channel. The telescopic drive component is set on the fire extinguisher conveying module, and the bottle gripping component moves back and forth above the fire extinguisher conveying module and the discharge platform.
[0009] As an optional technical solution of this utility model, a detection element is provided at the bottle placement position on the fire extinguisher delivery module.
[0010] As an optional technical solution of this utility model, the discharge platform includes a receiving platform and a feeding platform. The receiving platform is provided with a first channel, and the stepping pusher module is set on the receiving platform and pushes the fixture to move along the first channel. The feeding platform is provided with two limiting guides, and the area between the two limiting guides on the feeding platform is a second channel. The second channel is in the same direction as the first channel and is connected to it. The fixture return channel includes the first channel and the second channel.
[0011] As an optional technical solution of this utility model, a push-out clearance hole is provided on the first channel along the receiving platform. The step-push module includes a step-drive component and a pusher component. The step-drive component is located below the receiving platform. The pusher component passes through the push-out clearance hole and the pusher part of the pusher component is located above the receiving platform. The pusher component is connected to the actuating part of the step-drive component and is driven by the step-drive component to move back and forth along the push-out clearance hole.
[0012] As an optional technical solution of this utility model, a receiving area is provided on the receiving platform, and a receiving avoidance hole is provided on the receiving platform outside the receiving area, which is connected to the pushing avoidance hole.
[0013] Compared with the prior art, the advantages of this utility model are as follows: 1. The separation and return mechanism of this utility model can separate and rotate each fire extinguisher on the fixture, and at the same time return the empty fixture to the fire extinguisher loading station for use, which is conducive to realizing the automatic testing of fire extinguishers; 2. The stepping pusher module pushes the fixture on the discharge platform to move step by step. Each time the fixture stops, one fire extinguisher on the fixture is in the separation zone. At this time, the separation module can grab the fire extinguisher in the separation zone and place it on the fire extinguisher conveying module, realizing the separation of the fixture from each fire extinguisher on the fixture; 3. The fixture return channel of the discharge platform can be extended to the fire extinguisher loading station of the fire extinguisher testing equipment, so that the empty fixture can be directly reused.

Detailed Implementation
[0020] 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. Example
[0021] Please see Figures 1-4 A separation and return mechanism for a fire extinguisher fixture includes a discharge platform 1, a stepping pusher module 2, a fire extinguisher conveying module 3, and a separation module 4. The discharge platform 1 is provided with a fixture return channel and a separation zone. The stepping pusher module 2 is disposed on the discharge platform 1 and is used to push the fixture 5 on the discharge platform 1 to move along the fixture return channel. The fixture return channel passes through the separation zone, and during the movement of the fixture along the fixture return channel, each fire extinguisher 6 on the fixture 5 passes through the separation zone in sequence.
[0022] The stepping pusher module 2 pushes the fixture to move step by step. Each time the fixture pauses, a fire extinguisher 6 on the fixture 5 is in the separation zone. The separation module 4 grabs the fire extinguisher 6 and transfers it to the fire extinguisher conveying module 3. After each fire extinguisher 6 on the fixture 5 stops in the separation zone in sequence and is separated from the fixture by the separation module 4 in sequence, the empty fixture 5 is transported along the fixture return channel to the fire extinguisher loading station for reuse.
[0023] Please see Figure 4 After the fire extinguisher water test is completed, the robotic arm of the fire extinguisher water test equipment grabs multiple fixtures 5 from the test tank and places each fixture 5 onto the discharge platform 1 in sequence. The stepping pusher module 2 pushes each fixture 5 to move step by step along the fixture return channel. The separation module 4 removes the fire extinguishers 6 from each fixture 5 in sequence. While separating the fire extinguishers 6 from the fixtures 5, the module 5 is also sent back to the fire extinguisher loading station before the water test, realizing the reuse of the fixtures 5.
[0024] The separation module 4 includes a telescopic drive component 41 and a bottle-grabbing component 42. The telescopic drive component 41 is a telescopic part in the form of a telescopic cylinder, electric push rod, etc., and the bottle-grabbing component 42 is a fire extinguisher grabbing component in the form of an electromagnetic adsorption component, negative pressure adsorption component, etc. The telescopic part of the telescopic drive component 41 is connected to the bottle-grabbing component 42. The telescopic drive component 41 drives the bottle-grabbing component 42 to reciprocate between the bottle-grabbing position and the bottle-dropping position. The bottle-grabbing position is at the separation zone, and the bottle-dropping position is on the fire extinguisher delivery module 3. When the bottle-grabbing component 42 is at the bottle-grabbing position, it grabs the fire extinguisher in the separation zone. When the bottle-grabbing component 42 is at the bottle-dropping position, it places the grabbed fire extinguisher onto the fire extinguisher delivery module 3. While the fixture is being conveyed step by step, the bottle-grabbing component 42 reciprocates, so that each fire extinguisher on the fixture is sequentially transferred to the fire extinguisher delivery module 3.
[0025] In a preferred embodiment, the fire extinguisher conveying module 3 is a belt conveyor, positioned outside the discharge platform 1. The conveying direction of the fire extinguisher conveying module 3 is parallel to the direction of the fixture return channel. A telescopic drive component 41 is mounted on the frame of the fire extinguisher conveying module 3. Driven by the telescopic drive component 41, the bottle gripper 42 moves reciprocally between the fire extinguisher conveying module 3 and the discharge platform 1 above the fire extinguisher conveying module 3. The telescopic drive component 41 can also be replaced with a linear module.
[0026] The fire extinguisher delivery module 3 is equipped with a detection component 31, which is a photoelectric switch, proximity switch and other detection components. The detection component 31 is located at the bottle placement position and is used to detect whether the separation module 4 has placed the fire extinguisher in the bottle placement position.
[0027] The discharge platform 1 includes a receiving platform 11 and a feeding platform 12. The feeding platform 12 is equipped with two limiting guides 13, which are either limiting plates or limiting rods. The area defined by the two limiting guides 13 on the feeding platform 12 is a second channel, the end of which is located at the fire extinguisher loading station of the fire extinguisher testing equipment. The receiving platform 11 has a first channel. The stepping pusher module 2 is mounted on the receiving platform 11 and pushes the fixture on the receiving platform 11 to move along the first channel. The second channel runs in the same direction as the first channel, with the head of the second channel at the end of the first channel, connecting to the first channel. The second channel and the first channel together form a fixture return channel.
[0028] The receiving platform 11 is also provided with a pusher clearance hole 14. The pusher clearance hole 14 is a slot hole provided along the length direction of the first channel. The stepper pusher module 2 includes a stepper drive 21 and a pusher 22. The stepper drive 21 is a ball screw driven by a stepper motor. The stepper drive 21 is located below the receiving platform 11. The pusher 22 is provided through the pusher clearance hole 14. The pusher part of the pusher 22 is above the receiving platform 11. The pusher 22 is connected to the drive part of the stepper drive 21. The stepper drive 21 drives the pusher 22 to move back and forth along the pusher clearance hole 14.
[0029] The receiving platform 11 is also provided with a receiving area. The receiving platform 11 is provided with a receiving avoidance hole outside the receiving area. The receiving avoidance hole is connected to the pushing avoidance hole 14.
[0030] Please see Figures 1-4 In this embodiment, when the diversion and return mechanism is used in the fire extinguisher testing equipment, the receiving area of the receiving platform 11 is connected to the fixture waiting platform of the fire extinguisher testing equipment. After the fire extinguisher testing is completed, the fixtures loaded with fire extinguishers are placed on the fixture waiting platform and transferred to the receiving platform 11 one by one. Specifically, after the pusher 22 moves along the pusher clearance hole 14 to the receiving clearance hole, a fixture is moved from the fixture waiting platform to the receiving platform 11 through the receiving area. The stepping pusher module 2 pushes the fixture to move step by step along the fixture return channel. The separation module 4 takes out each fire extinguisher on the fixture and transfers it to the fire extinguisher conveying module 3 for conveying. After all the fire extinguishers on the fixture are separated, the pusher 22 of the stepping pusher module 2 moves along the pusher clearance hole 14 to the receiving clearance hole. The next fixture on the fixture waiting platform is transferred to the receiving platform 11 through the receiving area. The above operation is repeated until all the fire extinguishers in each fixture on the fixture waiting platform are separated, and the empty fixtures are returned to the fire extinguisher loading station of the fire extinguisher testing equipment for reuse.
