The output end of the gas guide slip ring is connected to the sealing cover through pipes.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention drives the rotation of the rotating disk through the output end of the hollow rotating platform, and the rotation of the rotating disk drives the rotation of the automatic lifting mechanism. The sliding rod and the first guide wheel of the lifting component of the automatic lifting mechanism rotate, so that the first guide wheel rolls on the first and second rings of the support component. When the first guide wheel is at the first support arc position of the first ring, the lower side of the sealing cover is away from the rotating disk, and the sealing cover is in an automatically open state at this time. When the first guide wheel moves from the first support arc position to the second support arc position, the first guide wheel is in a downward moving state. It stops when it moves to the second support arc position. The downward movement of the first guide wheel drives the sliding rod to move downward, and the downward movement of the sliding rod drives the sealing cover to move downward, so that the sealing cover automatically closes. At the same time, the second guide wheel of the automatic sealing mechanism rotates to the lower surface of the third and fourth support arcs. The upper side of the second guide wheel is limited by the third and fourth support arcs, and the second guide wheel cannot move upward. The second guide wheel fixes the sealing cover on the rotating disk through the sliding rod, and the sealing cover is dynamically locked. This is beneficial for automatically unlocking and opening the sealing cover before unloading and automatically closing and locking the sealing cover after loading.

[0022] 2. The support plate is placed on the lifting frame. Under the weight of the air purifier on the upper side of the support plate and the support plate itself, the lifting frame moves downward. The downward movement of the lifting frame drives the limit rod to move downward, and the spring undergoes elastic deformation and is compressed. The downward movement of the lifting frame drives the third guide wheel to move downward. The downward movement of the third guide wheel drives the rotating block, causing the rotating block to rotate and lock the support plate, forming a self-locking mechanism. When the support plate and the air purifier on its upper side are removed, the robotic arm clamps the air purifier and the support plate below it after the inspection is completed and moves it vertically upward a preset distance. The upward movement of the support plate causes the lifting frame to lose downward pressure. The elastically deformed spring returns to its original position and pushes the lifting frame back to its initial position. The upward movement of the lifting frame drives the fourth guide wheel to move upward. The upward movement of the fourth guide wheel drives the rotating block to rotate, and the rotating block opens and automatically unlocks. This facilitates automatic locking after the air purifier is placed and automatic unlocking when the air purifier is picked up.

[0023] 3. The carrier tray is temporarily stored on the second lifting and transfer machine via a double-speed chain conveyor. The robotic arm clamps the support plate and air purifier on the carrier tray and transports them to the gravity self-locking assembly. The support plate and air purifier on the rotating plate are clamped and transported to the carrier tray, which facilitates loading and unloading simultaneously. A formaldehyde dynamic gas generator produces a gas of a preset concentration, which is transported to the automatically locked sealed cover through the gas guide slip ring. The air purifier inside the sealed cover purifies the gas. The formaldehyde sensor detects the formaldehyde concentration before and after purification in the sealed cover. After the detection station completes the detection, the air purifier continues to start. After the formaldehyde in the sealed cover is completely removed at the remaining multiple pollutant removal stations, the material is unloaded at the unloading station to avoid the formaldehyde released during testing from polluting the external space of the sealed cover.

Detailed Implementation

[0040] 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] The present invention will be further described below with reference to embodiments.

[0042] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0043] Example 1: In some examples, please refer to Figures 1-13 A continuous performance testing device for air purifiers includes a frame 1. A continuous feeding mechanism 2 for continuously conveying air purifiers is installed on one side of the frame 1. A continuous testing mechanism 3 for continuously testing air purifiers is installed on the upper side of the frame 1. The continuous testing mechanism 3 includes: an auxiliary support fixture 31, a loading and unloading mechanism 32, a multi-station conveying and testing mechanism 33, and a pollution source conveying mechanism 34. The output end of the continuous feeding mechanism 2 is equipped with an auxiliary support fixture 31 for supporting the air purifier and connecting auxiliary lines. The loading and unloading mechanism 32 for continuously loading and unloading the auxiliary support fixture 31 is installed on the side of the frame 1 near the continuous feeding mechanism 2. The multi-station conveying and testing mechanism 33 for multi-station conveying and automatic sealing testing of the air purifier and its auxiliary support fixture 31 is installed in the middle of the frame 1. The pollution source conveying mechanism 34 for quantitatively and directionally conveying harmful gases and smoke to the multi-station conveying and testing mechanism 33 is installed in the middle of the frame 1.

[0044] The multi-station conveying and testing mechanism 33 includes: a rotary conveying mechanism, an automatic lifting mechanism, an automatic sealing mechanism, a testing component, and a gravity self-locking component. The rotary conveying mechanism is installed on the middle side of the frame 1. Multiple automatic lifting mechanisms are installed on the rotary conveying mechanism. The automatic sealing mechanism is installed on the automatic lifting mechanism. The testing component is installed on the automatic lifting mechanism. Multiple gravity self-locking components are installed on the rotary conveying mechanism. The gravity self-locking components and the automatic lifting mechanisms correspond one-to-one.

[0045] like Figure 2 , Figure 3 As shown, the rotary conveying mechanism includes a hollow rotary platform 331 and a rotary disk 332. The fixed end of the hollow rotary platform 331 is fixedly installed on the frame 1, and the rotary disk 332 is fixedly installed on the output end of the hollow rotary platform 331. An opening is provided in the middle of the rotary disk 332. Multiple automatic lifting mechanisms are arranged in a circular array on the rotary disk 332 with the center of the rotary disk 332 as the center. The hollow rotary platform 331 integrates a drive motor, which drives the mechanism.

[0046] The rotation of the output end of the hollow rotating platform 331 drives the rotating disk 332 to rotate, and the rotation of the rotating disk 332 drives the automatic lifting mechanism and the automatic sealing mechanism to rotate.

[0047] like Figure 5 , Figure 6 , Figure 7As shown, the automatic lifting mechanism includes a lifting assembly and a support assembly. Multiple lifting assemblies are arranged in a circular array on the rotating disk 332 with the center of the disk as the center. The support assembly is mounted on the upper side of the frame 1. Each lifting assembly includes a sliding rod 333, a sealing cover 334, and a first guide wheel 335. Multiple sliding rods 333 are slidably connected to the rotating disk 332. The sealing cover 334 is fixedly installed at the end of the sliding rod 333 away from the rotating disk 332. Two sliding rods 333 are located on the same diameter of the rotating disk 332. The first guide wheel 335 is rotatably connected to the lower side of the sliding rods 333 located on the same diameter of the rotating disk 332 via a bracket.

[0048] like Figure 8 As shown, the support assembly includes a first ring and a second ring, both of which are fixedly mounted on the frame 1. The centers of the first ring, the second ring, and the rotating disk 332 are located on the same axis perpendicular to the horizontal plane. The first ring includes a first supporting arc 336 and a second supporting arc 337, both of which are fixedly mounted on the frame 1. The first supporting arc 336 is located on the front side of the frame 1, and the second supporting arc 337 is located on the rear side of the frame 1. The first supporting arc 336 is higher than the second supporting arc 337. The ends of the first supporting arc 336 and the second supporting arc 337 are smoothly connected. The first ring and the second ring have the same structure but different sizes.

[0049] The rotating disk 332 drives the automatic lifting mechanism to rotate. The sliding rod 333 and the first guide wheel 335 of the lifting component of the automatic lifting mechanism rotate, causing the first guide wheel 335 to roll on the first and second rings of the support component. When the first guide wheel 335 is at the second support arc 337 position of the first ring, the lower side of the sealing cover 334 is in close contact with the rotating disk 332. When the first guide wheel 335 moves from the second support arc 337 position to the first support arc 336 position, the first guide wheel 335 is in an upward moving state. It stops at the first support arc 336 position. The upward movement of the first guide wheel 335 drives the sliding rod 333 to move upward. The upward movement of the sliding rod 333 drives the sealing cover 334 to move upward, causing the sealing cover 334 to open automatically. At this time, the untested air purifier can be transported to the area directly below the sealing cover 334 through the loading and unloading mechanism 32. The air purifier that has been tested is transported away from the area directly below the sealing cover 334 through the loading and unloading mechanism 32.

[0050] The first guide wheel 335 rolls on the first and second rings of the support assembly. When the first guide wheel 335 is at the first support arc 336 position of the first ring, the lower side of the sealing cover 334 is away from the rotating disk 332, and the sealing cover 334 is in the open state. When the first guide wheel 335 moves from the first support arc 336 position to the second support arc 337 position, the first guide wheel 335 is in the downward moving state. It stops when it moves to the second support arc 337 position. The downward movement of the first guide wheel 335 drives the sliding rod 333 to move downward. The downward movement of the sliding rod 333 drives the sealing cover 334 to move downward, so that the sealing cover 334 automatically closes.

[0051] like Figure 7 , Figure 8 As shown, the automatic sealing mechanism includes: a second guide wheel 338, a sealing ring 339, a third supporting arc 3310, and a fourth supporting arc 3311. The second guide wheel 338 is rotatably connected to the lower side of the sliding rod 333, which is located on the same diameter as the rotating disk 332, via a bracket. The sealing ring 339 is located directly below the sealing cover 334 and is fixedly installed on the rotating disk 332. The third supporting arc 3310 is fixedly installed on the middle side of the frame 1, and the fourth supporting arc 3311 is fixedly installed on the rear side of the frame 1. The centers of the third supporting arc 3310, the fourth supporting arc 3311, the first supporting arc 336, and the second supporting arc 337 are located on the same axis perpendicular to the horizontal plane. The lower surfaces of the third supporting arc 3310 and the fourth supporting arc 3311 are in close contact with the outer ring of the second guide wheel 338.

[0052] The rotation of the rotating disk 332 drives the automatic lifting mechanism and the automatic sealing mechanism to rotate. When the sealing cover 334 is in the open state, the second guide wheel 338 of the automatic sealing mechanism rotates, causing the second guide wheel 338 to rotate to the lower surface of the third support arc 3310 and the fourth support arc 3311. The upper side of the second guide wheel 338 is limited by the third support arc 3310 and the fourth support arc 3311, and the second guide wheel 338 cannot move upward. The second guide wheel 338 fixes the sealing cover 334 to the rotating disk 332 through the sliding rod 333. At this time, the first guide wheel 335 is located at the position of the second support arc 337, and the sealing cover 334 is in the automatic closed state. The sealing cover 334 squeezes the sealing ring 339, and the sealing ring 339 fills the gap between the sealing cover 334 and the rotating disk 332, which is conducive to automatically locking the sealing cover 334.

[0053] Example 2: In some embodiments, such as Figures 1-13As shown, in a preferred embodiment of the present invention, the detection component includes: a noise sensor 3312, a formaldehyde sensor 3313, and a dust sensor 3321. The noise sensor 3312 is fixedly installed inside a sealing cover 334, the formaldehyde sensor 3313 is fixedly installed inside a sealing cover 334, and the dust sensor 3321 is fixedly installed inside a sealing cover 334. Both the noise sensor 3312 and the formaldehyde sensor 3313 are electrically connected to an external controller.

[0054] like Figure 5 As shown, the noise sensor 3312 of the detection component detects the noise of the air purifier during operation and transmits an electrical signal to the external controller, which records the noise range. The formaldehyde sensor 3313 detects the formaldehyde concentration inside the sealed cover 334 before and after the air purifier starts, and transmits an electrical signal to the external controller, which records the formaldehyde concentration values ​​before and after purification. The dust sensor 3321 detects the particulate matter concentration inside the sealed cover 334 before and after the air purifier starts, and transmits an electrical signal to the external controller, which records the particulate matter concentration values ​​before and after purification.

[0055] like Figure 11 , Figure 12 As shown, the gravity self-locking assembly includes: a limiting rod 3314, a lifting frame 3315, a spring 3316, a third guide wheel 3317, a fourth guide wheel 3318, a rotating block 3319, and an elastic contact 3320. Multiple limiting rods 3314 are slidably connected to a rotating disk 332. The lifting frame 3315 is fixedly mounted on the limiting rods 3314. The center of the lifting frame 3315 and the center of the sealing cover 334 are located on the same axis perpendicular to the horizontal plane. The spring 3316 is sleeved on the limiting rod 3314, with one end of the spring 3316 tightly against the lifting frame 3315 and the other end tightly against the rotating disk 332. Multiple third guide wheels 3317 are rotatably connected to the lifting frame 3315 via a rotating shaft. Multiple fourth guide wheels 3317 and 3318 are also connected to the lifting frame 3315. 18 is rotatably connected to the lower side of the lifting frame 3315 via a rotating shaft. Multiple rotating blocks 3319 are arranged in a circular array around the center of the lifting frame 3315 on the rotating disk 332. The rotating blocks 3319 are rotatably connected to the rotating disk 332 via a rotating shaft. The fourth guide wheel 3318 corresponds to the rotating blocks 3319 one by one. The fourth guide wheel 3318 is located on the lower side of the end of the rotating block 3319 near the center of the lifting frame 3315. The third guide wheel 3317 corresponds to the rotating blocks 3319 one by one. The third guide wheel 3317 is located between the rotating shafts of the fourth guide wheel 3318 and the rotating blocks 3319, and the third guide wheel 3317 is located on the upper side of the rotating blocks 3319. Multiple elastic contacts 3320 are fixedly installed on the rotating disk 332.

[0056] Example 3: In some embodiments, such as Figures 1-13 As shown, in a preferred embodiment of the present invention, the continuous feeding mechanism 2 includes: a double-speed chain 21, a carrier tray 22 and a first lifting and transferring machine 23. The double-speed chain 21 is located on one side of the frame 1, and a plurality of carrier trays 22 are located at the output end of the double-speed chain 21. The first lifting and transferring machine 23 is fixedly installed on the double-speed chain 21.

[0057] like Figure 3 As shown, the output end of the double-speed chain 21 of the continuous feeding mechanism 2 moves, driving the carrier 22 to move. The movement of the carrier 22 drives the auxiliary support fixture 31 to move. An air purifier is placed on the auxiliary support fixture 31. The carrier 22 moves to the position of the first lifting and transferring machine 23. The first lifting and transferring machine 23 lifts and transports the carrier 22 to the position of the loading and unloading mechanism 32. The loading and unloading mechanism 32 loads and unloads the auxiliary support fixture 31 and the air purifier on the carrier 22.

[0058] like Figure 9 , Figure 10 As shown, the auxiliary support fixture 31 includes: a support plate 311, a socket 312, a first conductive ring 313, a second conductive ring 314, and a conductive sheet 315. The support plate 311 is located on the carrier plate 22. A circular slot 316 is formed in the middle of the support plate 311 to hold the air purifier. The socket 312 is fixedly installed on the support plate 311. The first conductive ring 313 and the second conductive ring 314 are both fixedly installed on the lower side of the support plate 311. The centers of the four are the same. The conductive sheet 315 is fixedly installed on the lower middle side of the support disk 311. The electrodes of the socket 312 are electrically connected to the first conductive ring 313, the second conductive ring 314 and the conductive sheet 315 respectively. The elastic contact 3320 corresponds one-to-one with the first conductive ring 313, the second conductive ring 314 and the conductive sheet 315. When the support disk 311 is placed on the rotating disk 332, the electrical connection is achieved through the contact between the elastic contact 3320 and the first conductive ring 313, the second conductive ring 314 and the conductive sheet 315.

[0059] like Figure 2 , Figure 3 As shown, the loading and unloading mechanism 32 includes a second lifting and transferring machine 321 and a robotic arm 322. The second lifting and transferring machine 321 is fixedly installed on the bracket of the double-speed chain 21, and one end of the second lifting and transferring machine 321 is located at the first lifting and transferring machine 23. The two robotic arms 322 are located on the left and right sides of the second lifting and transferring machine 321, and the fixed ends of the robotic arms 322 are fixedly installed on the frame 1.

[0060] The sealing cover 334 of the right robotic arm 322 of the loading and unloading mechanism 32 is the loading station, the sealing cover 334 of the left robotic arm 322 is the unloading station, the left rear side of the unloading station is the inspection station, and the remaining part is the pollutant removal station. The air purifier is clamped in the circular slot 316 in the middle of the support plate 311 of the auxiliary support fixture 31, and the power plug of the air purifier is plugged into the socket 312. At this time, the support plate 311 is placed on the carrier plate 22 and transported by the double speed chain 21. The carrier plate 22 is moved to the second lifting and transferring machine 321 by the first lifting and transferring machine 23 for temporary storage. The robotic arm 322 clamps the support plate 311 and the air purifier on the carrier plate 22 and transports them to the gravity self-locking component. The robotic arm 322 clamps the support plate 311 and the air purifier on the rotating plate 332 and transports them to the carrier plate 22.

[0061] The support plate 311 is placed on the lifting frame 3315. Under the weight of the air purifier on the upper side of the support plate 311 and the support plate 311 itself, the lifting frame 3315 moves downward. The downward movement of the lifting frame 3315 drives the limit rod 3314 to move downward. The spring 3316 undergoes elastic deformation and is compressed. The downward movement of the lifting frame 3315 drives the third guide wheel 3317 to move downward. The downward movement of the third guide wheel 3317 drives the rotating block 3319 to rotate and lock the support plate 311, forming a self-locking mechanism.

[0062] When the support plate 311 and the air purifier on its upper side are to be removed, the robotic arm 322 clamps the air purifier and the support plate 311 below it after the inspection is completed and moves it vertically upward a preset distance. The support plate 311 moves upward, causing the lifting frame 3315 to lose downward pressure. The elastically deformed spring 3316 returns to its original position and pushes the lifting frame 3315 back to its initial position. The upward movement of the lifting frame 3315 drives the fourth guide wheel 3318 to move upward. The upward movement of the fourth guide wheel 3318 drives the rotating block 3319 to rotate. The rotating block 3319 opens and unlocks automatically.

[0063] like Figure 4 As shown, the pollution source conveying mechanism 34 includes: a formaldehyde dynamic gas generator 341, a dust aerosol generator 3322, and a gas guide slip ring 342. The formaldehyde dynamic gas generator 341 and the dust aerosol generator 3322 are both fixedly installed on the lower side of the frame 1. The fixed end of the gas guide slip ring 342 is fixedly installed on the middle side of the frame 1. The rotating end of the gas guide slip ring 342 is located at the opening position of the rotating disk 332. The output ends of the formaldehyde dynamic gas generator 341 and the dust aerosol generator 3322 are both fixedly connected to the input end of the gas guide slip ring 342 through pipes. The output end of the gas guide slip ring 342 is connected to the sealing cover 334 through pipes.

[0064] The formaldehyde dynamic gas generator 341 of the pollution source delivery mechanism 34 can generate various concentrations of formaldehyde standard gas in real time. Activating the formaldehyde dynamic gas generator 341, in conjunction with the air guide slip ring 342, changes the formaldehyde concentration inside the automatically locked sealed cover 334 to a preset range. The formaldehyde is then purified by the air purifier inside the sealed cover 334. The formaldehyde sensor 3313 detects the formaldehyde concentration inside the sealed cover 334 before and after the air purifier starts. After the detection station completes the test, the air purifier continues to operate, reducing the formaldehyde concentration inside the sealed cover 334 to the preset range before proceeding to the next test, thus preventing the release of formaldehyde during testing. Formaldehyde pollutes the external space of the sealed cover 334. The dust aerosol generator 3322 is activated, and in conjunction with the air guide slip ring 342, the particulate matter concentration inside the automatically locked sealed cover 334 is changed to a preset range. The air is then purified by the air purifier inside the sealed cover 334. The dust sensor 3321 detects the particulate matter concentration inside the sealed cover 334 before and after the air purifier is activated. After the detection is completed at the detection station, the air purifier continues to start to avoid the particulate matter released during the test from polluting the external space of the sealed cover 334. After the particulate matter concentration inside the sealed cover 334 is reduced to the preset range, the material can be unloaded at the unloading station.

[0065] In addition, such as Figure 13 As shown, another identical continuous detection mechanism 3 can be set on the other side of the continuous feeding mechanism 2 for detection to improve detection efficiency.

Although the present invention 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 of the technical features.
