Description

Technical Field

[0001] This utility model relates to fire extinguisher production and testing equipment, specifically to a fire extinguisher water testing device. Background Technology

[0002] Before being used, inflatable fire extinguishers need to undergo a water test to determine if they leak. A common method is to use a water testing device to inflate the extinguisher and then immerse it in water for a certain period. The presence of air bubbles is then observed to determine if the extinguisher is leaking.

[0003] Traditional fire extinguisher testing equipment uses a sequential, cyclical testing method, requiring manual labor or conveyor equipment to move fire extinguishers to the testing station. This is labor-intensive and inefficient. While some existing testing equipment can simultaneously test multiple fire extinguishers in groups, effectively improving efficiency compared to traditional methods, these systems still require manual assembly of the fire extinguishers before and separation of the groups after testing, limiting the overall efficiency improvement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fire extinguisher testing device that can test multiple fire extinguishers simultaneously, and can arrange the fire extinguishers in a group before testing and separate the group of fire extinguishers after testing.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a fire extinguisher testing device, including a material placement mechanism, a testing mechanism, and a discharging mechanism. The material placement mechanism includes a transfer platform, a material placement platform, a bottle filling assembly, and a material placement component.

The discharging mechanism includes a waiting platform, a discharging component, a discharging platform, a stepping ejection assembly, a separation assembly, and a fire extinguisher output assembly. One by one, the fixtures on the waiting-to-discharge platform are transferred to the discharge platform. The discharge platform is equipped with a fixture return channel and a separation zone. The stepping pusher component pushes the fixtures on the discharge platform along the fixture return channel through the separation zone and to the transfer platform. The separation component grabs the fire extinguishers from the fixtures in the separation zone and places them on the fire extinguisher output component. The water testing mechanism includes a moving grabbing component and a water testing tank. The moving grabbing component grabs the fixtures on the placement platform and transfers them to the water testing tank, and then grabs the fixtures in the water testing tank and transfers them to the waiting-to-discharge platform. The placement mechanism loads the fire extinguishers into the fixtures and places the fixtures on the placement platform. The water testing mechanism grabs multiple fixtures from the placement platform and places them into the water testing tank for testing. After testing, the multiple fixtures are placed on the waiting-to-discharge platform. The discharge mechanism separates the fire extinguishers from each fixture and returns the empty fixtures to the placement platform mechanism.

[0006] As an optional embodiment of this invention, the bottling assembly includes a fire extinguisher input assembly and a bottling moving part. The moving part of the bottling moving part reciprocates between a bottling standby position and a bottling position. During the stepping movement of the fixture towards the transfer platform, the bottling moving part sequentially loads the fire extinguishers from the fire extinguisher input assembly onto the fixture. During the stepping movement of the empty fixture towards the transfer platform, the bottling assembly matches the movement frequency of the empty fixture, thereby filling the empty fixture with fire extinguishers.

[0007] As an optional solution of this utility model, the material placement platform is provided with a feeding channel.

The material placement component includes a material placement telescopic component and a material placement component. The telescopic part of the material placement telescopic component is connected to the material placement component. The material placement telescopic component drives the material placement component to push the fixtures on the transfer platform to the positioning area and arranges the fixtures on the material placement platform along the feeding channel. After the material placement component pushes the fixtures to the positioning area, the positioning adjustment component adjusts the position of the fixtures. Then, when the material placement component pushes the fixtures to the positioning area again, it can push the fixtures originally in the positioning area into the feeding channel, so that the fixtures move along the feeding channel and are neatly arranged along the feeding channel.

[0008] As an optional solution of this utility model, a material-swinging clearance hole is provided on the transfer platform along the direction of the feeding channel, and a material-swinging telescopic component is provided below the material-swinging platform.

[0009] As an optional solution of this utility model, a discharge channel is provided on the discharge platform, and a discharge area is provided at the end of the discharge channel on the discharge platform. The discharge platform is located at the discharge end of the discharge channel, and the platform surface is connected to the discharge area. The discharge component includes a discharge drive and a discharge component. The actuating part of the discharge drive is connected to the discharge component. The discharge drive drives the discharge component to push the fixture on the discharge platform to the discharge area along the discharge channel. After the stepping ejection component is in place, it pushes the fixture in the discharge area onto the discharge platform. The stepping ejection component includes a stepping drive and a pusher. The stepping drive is located on the discharge platform, and the actuating part of the stepping drive is connected to the pusher. The stepping drive drives the pusher to move stepwise along the fixture return channel. The stepping ejection component pushes the fixtures on the discharge platform away. After the stepping ejection component is in place, the discharge component pushes a fixture from the unloading platform onto the discharge platform. This not only separates the fixtures on the unloading platform, but also facilitates the removal of the fire extinguishers from each fixture in cooperation with the separation component.

[0010] As an optional solution of this utility model, a receiving area is provided on the discharge platform, which is connected to the waiting area. A push-out clearance hole is provided on the discharge platform along the jig return channel. The stepper drive is located below the discharge platform.

[0011] And / or,

[0012] The platform to be discharged has a discharge clearance hole along the discharge channel. The discharge drive is located below the platform to be discharged.

The lifting drive is mounted on the moving vehicle, and its lifting part is connected to the gripping component to adjust its height. The gripping component includes a gripping base, a gripping plate, and a gripping telescopic component. The gripping base is connected to the lifting part of the lifting drive. Two sets of gripping telescopic components are symmetrically arranged on the gripping base. The telescopic part of the gripping telescopic component is equipped with a gripping plate, and the gripping telescopic component drives the gripping plate to reciprocate between the gripping standby position and the gripping position. The moving vehicle and the lifting drive cooperate to move and adjust the lifting of the gripping component, enabling the gripping component to grab the fixture on the material placement platform and transfer it into the test tank, and then grab the fixture in the test tank and transfer it into the waiting-to-exit platform.

[0030] 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

[0031] like Figure 1 and Figure 2 As shown, a fire extinguisher testing device includes a material placement mechanism 1, a testing mechanism 2, a discharging mechanism 3, and multiple fixtures 4 used in conjunction with it. Each fixture 4 has multiple placement positions for placing fire extinguishers 5. The material placement mechanism 1 includes a transfer platform 11, a material placement platform 12, a bottling assembly 13, and a material placement assembly 14. During the process of pushing the fixtures 4 onto the transfer platform 11, the bottling assembly 13 loads the inflated fire extinguishers 5 onto the fixtures 4, ensuring that each placement position on the fixtures 4 has a fire extinguisher 5. After multiple fire extinguishers 5 are loaded onto the fixtures 4, the material placement assembly 14 places the fixtures 4 loaded with fire extinguishers 5 onto the material placement platform 12.

[0032] The water testing mechanism 2 includes a mobile gripping component and a water testing tank 21. The mobile gripping component grips multiple jigs 4 placed on the material placement platform 12 and places the gripped jigs 4 into the water testing tank 21 for water testing. After the water testing is completed, the mobile gripping component grips multiple jigs 4 in the water testing tank 21 and places them onto the discharge platform 31 of the discharge mechanism 3.

[0033] The discharge mechanism 3 includes a waiting platform 31, a discharge component 32, a discharge platform 33, a stepping ejection component 34, a separation component 35, and a fire extinguisher 5 output component 36. The moving gripping component places multiple fixtures 4 onto the waiting platform 31. When the stepping ejection component 34 is in place, the discharge component 32 pushes a fixture 4 onto the discharge platform 33. The stepping ejection component 34 pushes the fixture 4 stepwise, and each fire extinguisher 5 on the fixture 4 passes sequentially through the gripping position of the separation component 35. Each time the fixture 4 stops, there is one fire extinguisher on it. Fire extinguishers 5 are in the gripping position of the separation component 35. The separation mechanism cooperates with the stepping ejection component 34, allowing the separation mechanism to grip each fire extinguisher 5 on the fixture 4 and transfer it to the fire extinguisher 5 output component 36. Then, the stepping ejection component 34 resets and is in place. At this time, the discharging mechanism 3 pushes another fixture 4 onto the discharging platform 33. While the stepping ejection component 34 pushes the next fixture 4 step by step, the fixture 4 also pushes the fixture 4 in front towards the transfer platform 11, so that the empty fixture 4 in front flows back to the transfer platform 11. The bottling component 13 also cooperates with the stepping ejection component 34. The empty fixture 4 stops at each placement position when passing the bottling position of the bottling component 13, so that the bottling component 13 can fill the empty fixture 4 with fire extinguishers 5 at the transfer platform 11.

[0034] In the fire extinguisher 5 testing device of this utility model, the bottling assembly 13 and the stepping ejection assembly 34 cooperate to automatically load fire extinguishers 5 into each placement position of the fixture 4. The material placement assembly 14 can place the fixture 4 loaded with fire extinguishers 5 onto the material placement platform 12. The moving gripping assembly transfers multiple fixtures 4 placed on the material placement platform 12 to the test tank 21 for testing. After the test, the multiple fixtures 4 in the test tank 21 are transferred to the waiting platform 31. The discharging assembly 32, the stepping ejection assembly 34 and the separation assembly 35 cooperate to make each fixture 4 on the material placement platform 12 flow back to the transfer platform 11 one by one. During the flow of fixtures 4, each fire extinguisher 5 on the fixture 4 is removed one by one. The fixtures 4 that flow back to the transfer platform 11 are reloaded with fire extinguishers 5 by the bottling assembly 13 for use.

[0035] Please see Figures 1-4 as well as Figure 7 The material placement platform 12 is equipped with a feeding channel. Specifically, the material placement platform 12 is equipped with two material placement guides, which are in the form of baffles or stops. The area between the two material placement guides on the material placement platform 12 is the feeding channel. The width of the feeding channel matches the length of the fixture 4. The fixture 4 can move along the feeding channel without deflecting on the material placement platform 12 during the movement. After multiple fixtures 4 move along the feeding channel and are placed on the material placement platform 12, these fixtures 4 are in a neatly arranged state.

[0036] The material placement platform 12 has a positioning area at the entrance of the feeding channel. The positioning platform 12 has a positioning adjustment component 15 at the positioning area. The positioning adjustment component 15 includes a positioning telescopic component. The telescopic part of the positioning telescopic component is equipped with a push plate. The telescopic direction of the positioning telescopic component is perpendicular to the direction of the feeding channel. When the fixture 4 is in the positioning area, it needs to be aligned with the feeding channel in order to be pushed smoothly into the feeding channel. The positioning telescopic component drives the push plate to move, and by pushing the fixture 4 to move, the fixture 4 can be positioned in the corresponding feeding channel. At this time, the fixture 4 can be smoothly pushed into the feeding channel along the feeding channel.

[0037] In some embodiments, the positioning adjustment components 15 are configured as two sets, with the two positioning adjustment components 15 located on both sides of the feed channel. When the fixture 4 is transferred to the positioning area, it is between the two positioning adjustment components 15. The fixture 4 can be adjusted when it deviates to either side of the feed channel. In other embodiments, the positioning adjustment components 15 are configured as a set and located on one side of the feed channel. The material guide on the side away from the positioning adjustment components 15 extends to the position of the positioning area corresponding to the positioning adjustment component 15. The fixture 4 can only deviate to the side closer to the positioning adjustment component 15 in the positioning area, so that it can be adjusted and positioned by one positioning adjustment component 15.

[0038] Preferably, the positioning telescopic component is located below the material placement platform 12, and the push plate is located outside the material placement platform 12 and connected to the telescopic part of the positioning telescopic component. The push plate extends from outside the material placement platform 12 above the material placement platform 12, and the part of the push plate above the material placement platform 12 is provided with a pushing part or bent inward into the material placement platform 12 to form a pushing part.

[0039] A transfer platform 11 is located at the entrance of the feeding channel. The platform surface of the transfer platform 11 is connected to the positioning area, and the fixture 4 on the transfer platform 11 can be directly pushed into the positioning area. Furthermore, a movable support for the fixture 4 is provided on the loading platform 12. The movable support includes support rods, which are arranged along the feeding channel. The upper edge of each support rod forms a loading support surface, extending to the positioning area. The platform surface of the transfer platform 11 is connected to the loading support surface, and the fixture 4 on the transfer platform 11 is positioned on the loading support surface when pushed into the positioning area. Optionally, the support rods are round rods and there are at least two of them. When the fixture 4 moves along the feeding channel, it is supported by the movable support. The contact area between the fixture 4 and the loading platform 12 is small, resulting in low friction, which facilitates the movement of the fixture 4.

[0040] The material placement assembly 14 includes a material placement telescopic component and a material placement component. The telescopic part of the material placement telescopic component is connected to the material placement component, and the material placement telescopic component drives the material placement component to move along the direction of the feeding channel. The material placement component moves from the outside of the transfer platform 11 along the feeding channel to the material placement platform 12, which can push the fixture 4 on the transfer platform 11 to the positioning area. Furthermore, by pushing the fixture 4 on the transfer platform 11, the fixture 4 after the positioning area is adjusted and aligned is also pushed into the feeding channel. Moreover, through the transfer platform 11 and the fixture 4 in the positioning area, each fixture 4 in the feeding channel is also pushed into the feeding channel, so that multiple fixtures 4 are neatly placed on the material placement platform 12 along the feeding channel.

[0041] The material-laying telescopic component is located below the material-laying platform 12 to avoid affecting the movement of the fixture 4 between the transfer platform 11 and the material-laying platform 12. The material-laying telescopic component extends and retracts along the direction of the feeding channel. The transfer platform 11 is provided with a material-laying clearance hole, which is a strip-shaped slot along the direction of the feeding channel. The material-laying component passes through the material-laying clearance hole and the material-laying part of the material-laying component is above the transfer platform 11. The material-laying telescopic component drives the material-laying component to move back and forth between the material-laying position and the material-laying standby position along the material-laying clearance hole. When the material-laying component is in the material-laying standby position, the material-laying component is away from the material-laying platform 12 and avoids the area where the fixture 4 moves on the transfer platform 11. When the material-laying component moves from the material-laying standby position to the material-laying position, the material-laying part of the material-laying component contacts the fixture 4 on the transfer platform 11 and pushes the fixture 4 towards the positioning area. The material-laying part of the material-laying component is preferably plate-shaped, with a large contact area between the material-laying part and the fixture 4, or it can directly contact multiple fire extinguishers 5, thereby promoting the stable movement of the fixture 4.

[0042] The transfer platform 11 is equipped with detection elements such as photoelectric switches and proximity switches to detect the position of the fixture 4 on the transfer platform 11. After the fixture 4 moves into place on the transfer platform 11, the material handling mechanism 1 pushes the fixture 4 on the transfer platform 11 toward the material handling platform 12.

[0043] The bottling assembly 13 includes a fire extinguisher 5 input assembly and a bottling moving component. The fire extinguisher 5 input assembly is a fire extinguisher 5 conveyor. The fire extinguisher 5 conveyor assembly can be connected to the discharge end of the fire extinguisher 5 inflation device, so as to convey the inflation-filled fire extinguisher 5. The fire extinguisher 5 conveyor assembly can also be equipped with a filling station, so that the inflation-filled fire extinguisher 5 can be loaded onto the fire extinguisher 5 input assembly by means of equipment or manual means.

[0044] The bottle-loading moving component is used to transfer the fire extinguishers 5 from the fire extinguisher input assembly to the fixture 4. The moving part of the bottle-loading moving component reciprocates between the bottle-loading standby position and the bottle-loading position. During the stepping movement of the fixture 4 towards the transfer platform 11, the bottle-loading moving component sequentially loads each fire extinguisher 5 from the fire extinguisher input assembly onto the fixture 4. As a specific example, the bottle-loading moving component is a telescopic component in the form of a telescopic cylinder, electric push rod, etc. The bottle-loading moving component is set on the frame of the fire extinguisher input assembly. The moving part of the bottle-loading moving component is equipped with a bottle-pushing component, which is located above the conveying surface of the fire extinguisher input assembly. When the fire extinguisher input assembly inputs the fire extinguisher 5 to the bottle-pushing component, the moving part of the bottle-loading moving component moves from the bottle-loading standby position to the bottle-loading position, and uses the bottle-pushing component to push the fire extinguisher 5 at the bottle-pushing component onto the fixture 4. The bottle-filling moving component can also use a linear motion module in conjunction with the bottle-grabbing assembly to grab the fire extinguisher 5 on the input component and place it onto the fixture 4.

[0045] The fire extinguisher 5 input component, the bottle moving component and the stepping ejection component 34 cooperate. When the fixture 4 moves a distance the size of the outer diameter of the fire extinguisher 5, the bottle moving component loads a fire extinguisher 5 onto the fixture 4, so that the fixture 4 is eventually filled with fire extinguishers 5, and then the material placement component 14 places it onto the material placement platform 12.

[0046] Please see Figure 1 , Figure 2 , Figure 5 and Figure 7 The platform 31 is equipped with a discharge channel and two discharge guides, which are in the form of baffles or bars. The area defined by the two discharge guides on the platform 31 is the discharge channel, similar to the feeding channel on the loading platform 12. The width of the discharge channel is adapted to the length of the fixture 4, allowing the fixture 4 to move along the discharge channel without deflecting on the loading platform. When the testing mechanism 2 transfers the multiple fixtures 4 after testing to the platform 31, each fixture 4 is neatly arranged along the discharge channel.

[0047] The waiting platform 31 has a waiting area at the end of the discharge channel, and the discharge platform 33 is located at the discharge end of the discharge channel, with its platform surface connected to the waiting area. To facilitate the movement of the fixture 4, the waiting platform 31 is also equipped with a fixture 4 moving support. Each support rod of the fixture 4 moving support is arranged along the discharge channel, and the upper edge of each support rod forms a discharge support surface. The support rod extends to the waiting area, and the platform surface of the discharge platform 33 is connected to the discharge support surface.

[0048] The discharge assembly 32 includes a discharge drive and a discharge component. The discharge drive is a lead screw module or a telescopic component. The discharge drive is mounted on the discharge platform 31, and its actuating part is connected to the discharge component. The discharge drive drives the discharge component to move along the discharge channel, thereby pushing each fixture 4 on the discharge platform 31 to move along the discharge channel towards the discharge platform 33. Furthermore, the discharge platform 31 is provided with a discharge clearance hole, which is a strip-shaped slot along the discharge channel. The discharge drive is positioned below the discharge platform 31, and the discharge component passes through the discharge clearance hole with its discharge portion above the discharge platform 31. This design, where the discharge drive is positioned below the discharge platform 31 and the discharge platform 31 has a discharge clearance hole, not only prevents the discharge assembly 32 from affecting the movement of the fixture 4 on the discharge platform 31 but also facilitates the integration of the various components of the equipment. The discharge section of the discharge component can also be plate-shaped, which has a larger contact area with the fixture 4 when pushing the fixture 4 to move, or can contact multiple fire extinguishers 5, which is conducive to pushing the fixture 4 to move stably.

[0049] The discharge platform 33 is equipped with a jig 4 return channel and a separation zone. A stepping ejector assembly 34 is mounted on the discharge platform 33. After the jig 4 is transferred from the waiting platform 31 to the discharge platform 33, the stepping ejector assembly 34 pushes the jig 4 along the jig 4 return channel. The jig 4 passes through the separation zone and finally reaches the transfer platform 11. Specifically, the stepping ejector assembly 34 pushes the jig 4 on the discharge platform 33 to move step-by-step along the jig 4 return channel. The distance the jig 4 moves each time is slightly greater than the outer diameter of the fire extinguisher 5. During the movement of the jig 4, whenever a fire extinguisher 5 is in the separation zone, the jig 4 pauses its movement. After the separation assembly 35 removes the jig 4 from the separation zone, the jig 4 continues to move, thus achieving the separation of each fire extinguisher 5 on the jig 4.

[0050] During the process of the stepper pusher component pushing the fixture 4 to move along the return channel of the fixture 4, each time the fixture 4 pauses to move, a placement position of the fixture 4 at the transfer platform 11 is in the bottling position of the bottling component 13, and the bottling component 13 puts the fire extinguisher 5 into the placement position.

[0051] The stepping ejection assembly 34 includes a stepping drive and a pusher. The stepping drive is a stepping telescopic component or a lead screw module driven by a stepping motor. The stepping drive is set on the discharge platform 33. The actuating part of the stepping drive is connected to the pusher. The stepping drive drives the pusher to move along the return channel of the fixture 4.

[0052] The discharge platform 33 is provided with a receiving area, which is connected to the waiting area. After the stepper ejector component 34 is in place, the discharge component 32 pushes the fixture 4 in the waiting area onto the receiving area on the discharge platform 33. The discharge platform 33 is provided with an ejection clearance hole along the return channel of the fixture 4. The ejection clearance hole is a strip-shaped groove along the return channel of the fixture 4. The stepper drive component is located below the discharge platform 33. The pusher component passes through the ejection clearance hole and connects to the actuating part of the stepper drive component, and the pusher part of the pusher component is above the discharge platform 33.

[0053] The discharge platform 33 is also provided with a receiving clearance hole, which is located at the end of the ejection clearance hole away from the transfer platform 11, and the receiving clearance hole communicates with the ejection clearance hole. When the stepping ejection assembly 34 is in place, the pusher is in the ejection clearance hole. At this time, the fixture 4 will not touch the pusher during the process of transferring from the waiting platform 31 to the discharge platform 33, and the pusher can directly push the fixtures 4 in the return channel of the fixture 4 to move by moving along the return channel of the fixture 4.

[0054] The stepper drive pushes the pusher to move back and forth along the return channel of the fixture 4. After the pusher pushes the fixture 4 to move a distance equal to the length of the fixture 4, the pusher returns to the ejection clearance hole to wait for the next fixture 4 to be pushed onto the discharge platform 33. The pusher can move multiple fixtures 4 continuously by moving within a short stroke range.

[0055] The waiting-to-discharge platform 31 is equipped with positioning detection elements such as photoelectric switches and proximity switches at the waiting-to-discharge area to detect the position of the fixture 4 at the waiting-to-discharge area. The positioning detection elements, the stepping push assembly 34, and the discharge assembly 32 work together. When the foremost fixture 4 on the waiting-to-discharge platform 31 reaches the waiting-to-discharge area, the discharge assembly 32 stops. When the pusher reaches the receiving clearance hole, the fixture 4 in the waiting-to-discharge area is pushed onto the discharge platform 33. Only after the pusher is in the push clearance hole does the discharge assembly 32 push the fixture 4 in the waiting-to-discharge area onto the discharge platform 33.

[0056] The separation assembly 35 includes a separation moving part and a bottle-grabbing part. The moving part of the separation moving part is connected to the bottle-grabbing part. The separation moving part drives the bottle-grabbing part to move back and forth between the separation zone and above the fire extinguisher 5 delivery assembly. When the separation moving part drives the bottle-grabbing part in the separation zone, the bottle-grabbing part grabs the fire extinguisher 5 in the separation zone. When the separation moving part drives the bottle-grabbing part to move above the fire extinguisher 5 delivery assembly, the bottle-grabbing part releases the grabbed fire extinguisher 5, and the fire extinguisher 5 is placed on the fire extinguisher 5 delivery assembly. The bottle-grabbing part is an electromagnetic adsorption component or a negative pressure adsorption component.

[0057] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7The mobile gripping assembly includes a truss 22, a moving vehicle 23, a lifting drive 24, and a gripping component 25. One or more test tanks 21 are provided and are located between the material placement platform 12 and the waiting platform 31. The material placement platform 12, each test tank 21, and the waiting platform 31 are arranged in a straight line. The truss 22 is erected above the material placement platform 12, the waiting platform 31, and the test tanks 21. The moving vehicle 23 is provided on the truss 22, and a moving rail is also provided on the truss 22. The moving vehicle 23 is equipped with a moving drive. The moving vehicle is located on the truss 22 and moves along the moving rail above the material placement platform 12, above each test tank 21, and above the waiting platform 31 under the drive of the moving drive. The mobile vehicle 23 is equipped with a lifting drive component 24, which can be a vertically arranged cylinder, hydraulic cylinder, electric push rod, etc., or it can be replaced by a vertically arranged linear module. The lifting part of the lifting drive component 24 is connected to the gripper 25, and the lifting drive component 24 drives the gripper 25 to lift and adjust.

[0058] The gripper 25 is used to grip multiple fixtures 4. The gripper 25 includes a gripping base, gripping plates, and gripping telescopic components. The gripping base is connected to the lifting part of the lifting drive 24. Two sets of gripping telescopic components are provided on the gripping base. Each gripping telescopic component includes one or more telescopic parts that extend synchronously and in parallel directions. The extension directions of the two sets of gripping telescopic components are parallel, and the two sets of gripping telescopic components are symmetrically arranged. Each telescopic part of the gripping telescopic component is provided with a gripping plate. The gripping telescopic component drives the gripping plate connected to it to reciprocate between the gripping standby position and the gripping position. When the gripping plate is in the gripping position, the two gripping plates are in a position close to each other, and the two gripping plates cooperate to grip each fixture 4 located between them. When the gripping plate is in the gripping standby position, the two gripping plates are in a position far apart from each other, and do not grip the items between them.

[0059] As an optional implementation, the gripping base is also provided with a reinforcing guide rail, and the gripping plate is provided with a reinforcing plate. The reinforcing plate cooperates with the reinforcing guide rail. During the process of the gripping telescopic component driving the gripping plate to move, the reinforcing plate moves along the reinforcing guide rail, thereby improving the strength and stability of the gripping plate.

[0060] As a further embodiment, the opposing side plates of the two gripping plates are provided with hanging members 251. The hanging members 251 are in the form of horizontally arranged support plates or support rods, etc. The two opposite outer end faces of the jig 4 are provided with hanging grooves 41. When the gripping member 25 grips the jig 4, the hanging members 251 are embedded in the hanging grooves 41 and cooperate with the hanging grooves 41 to improve the gripping effect of the gripping member 25 on the jig 4.

[0061] After the moving vehicle 23 moves above the material placement platform 12, the telescopic drive component drives the gripper 25 to descend onto the material placement platform 12. The gripper 25 grabs each fixture 4 on the material placement platform 12. The telescopic drive component drives the gripper 25 to rise and the moving vehicle 23 moves above the test tank 21. The telescopic drive component drives the gripper 25 to descend. After each fixture 4 is submerged in the water of the test tank 21, the gripper 25 releases the fixture 4 and the telescopic drive component drives the gripper 25 to rise. When there are multiple test tanks 21, after a certain number of fixtures 4 are placed on the material placement platform 12, the moving gripper component grabs the fixtures 4 from the material placement platform 12 and places them into another test tank 21. After the fixture 4 in a certain test tank 21 completes the test, the moving vehicle 23 moves above the test tank 21. The telescopic drive causes the gripper 25 to descend and grab multiple fixtures 4 in the test tank 21. After the telescopic drive causes the gripper 25 to rise, the moving vehicle 23 moves above the waiting platform 31. The telescopic drive causes the gripper 25 to descend and place the grabbed fixture 4 on the waiting platform 31. The discharge mechanism 3 sorts out the fire extinguishers 5 from each fixture 4 and returns each fixture 4 to the material placement mechanism 1. The material placement mechanism 1 loads fire extinguishers 5 onto the empty fixtures 4 and then places them back onto the material placement platform 12.

[0062] Each of the 21 test tanks is also equipped with a video detection system. After the extinguishing gas is submerged in water for a period of time, the video detection system checks for air bubbles to determine the airtightness of the batch of fire extinguishers 5. When air bubbles are detected, an alarm signal is issued. Operators can then examine each fire extinguisher 5 in the batch to identify any defective products.

[0063] In some implementations, the water testing equipment of this embodiment can also be used in conjunction with a PLC control system to complete automatic water testing, which greatly helps to improve the efficiency of water testing of fire extinguishers 5 and reduce the labor intensity of personnel.
