[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] It will be understood that the terms "first," "second," etc. used herein may be used to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element.

[0041] like Figure 1 and Figure 3 As shown, in one embodiment, a noise barrier performance testing platform is proposed, the platform comprising:

[0042] Main frame 1: includes two mounting plates 101 provided on the main frame 1, each of which is provided with a circulation groove 102, a detection platform 103 fixedly mounted on the mounting plates 101, a detection feedback device mounted on the detection platform 103, and a genuine product ramp 104 and a negative product ramp 105 fixedly mounted on the two mounting plates 101, respectively. Multiple rolling balls are rotatably mounted on the genuine product ramp 104 and the negative product ramp 105, and a sound generator 106 is also included and mounted on the mounting plates 101;

[0043] Positioning mechanism 2: Multiple positioning mechanisms are provided and mounted on the mounting plate 101. They include four positioning rods 201 mounted on the mounting plate 101 for positioning the sound insulation blank 205, multiple supporting rotating balls 202 for supporting the sound insulation blank 205, the supporting rotating balls 202 being rotatably mounted on the circular plate 203, and a rectangular sealing block 204 mounted on the mounting plate 101 for sealing the surface of the sound insulation blank 205.

[0044] Moving mechanism 3: used to drive the positioning rod 201 to position the sound insulation blank 205;

[0045] Follower mechanism 4: used to place the positioned sound insulation blank 205 on the rectangular sealing block 204;

[0046] Swing mechanism 5: used to drive the circular plate 203 to swing to cut the sound insulation blank 205;

[0047] The guiding mechanism 6 is used to stably guide the blanked sound insulation blank 205 .

[0048] In actual application of the embodiment of the present invention, when testing the sound insulation blank 205, as shown in FIG. Figure 1 and Figure 3 As shown, the sound insulation blank 205 is placed on the supporting rotating ball 202 by an external grasping device. Under the external driving action, the supporting rotating ball 202 begins to circulate. At this time, as the supporting rotating ball 202 moves, the four positioning rods 201 are moved close to the sound insulation blank 205 and pushed to the center by the action of the moving mechanism 3, thereby achieving the purpose of automatically and precisely positioning the sound insulation blank 205. The positioning rods 201 move downward synchronously while pushing the sound insulation blank 205. The descent of the positioning rods 201 avoids motion interference with the subsequent feeding of the sound insulation blank 205. During the movement of the positioning rods 201, the circular plate 203 is synchronously driven downward by the action of the follower mechanism 4, and the sound insulation blank 205 is then driven downward by the supporting rotating ball 202. At this time, when the sound insulation blank 205 is precisely positioned, the sound insulation blank 205 falls onto the surface of the rectangular sealing block 204, as shown in FIG. Figure 1As shown, when the sound insulation blank 205 arrives below the inspection platform 103 with the movement of the support rotating ball 202, the detection feedback device on the inspection platform 103 moves downward and presses against the sound insulation blank 205. The pressing force causes the sound insulation blank 205 to fit and seal with the rectangular sealing block 204. At this time, the sound generator 106 starts to operate, emitting a test sound. The detection feedback device receives the sound and determines the sound intensity. The signal from the detection feedback device is fed back to the swing mechanism 5. If the intensity meets the standard of qualified products, the swing mechanism 5 at the qualified product end is activated. After the inspection platform 103 is reset, the support rotating ball 202 continues to move. Under the action of the swing mechanism 5, the support rotating ball 202 tilts toward the end of the genuine product slope 104. At this time, the sound insulation blank 205 slides along the support rotating ball 202 under the action of gravity onto the guide mechanism 6, and then slides onto the genuine product slope 104 through the guide mechanism 6, thereby achieving the purpose of automatically sorting the sound insulation blanks 205.

[0049] like Figure 3 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 12 As shown, as a preferred embodiment of the present invention, the moving mechanism 3 includes a cross rod 301 fixedly connected to one end of the positioning round rod 201, a compression spring 302 is fixedly installed on the surface of the cross rod 301, and the other end of the compression spring 302 is connected to the sliding block 303, the cross rod 301 is slidably connected to the sliding block 303, and a reset spring 304 is also fixedly installed on the surface of the sliding block 303, an arc-shaped opening is opened on the surface of the cross rod 301, and further includes a spiral blade 305 that cooperates with the arc-shaped opening on the cross rod 301, the spiral blade 305 is fixedly installed on the inner wall of the linkage rotating cylinder 306, and the trajectory radius of the spiral blade 305 gradually decreases, and a rotating gear 307 is coaxially fixedly installed on the surface of the linkage rotating cylinder 306, and a fixed rack 308 and a reset rack 309 that cooperate with the rotating gear 307 are fixedly installed on the surface of the mounting plate 101.

[0050] In practical application of the embodiment of the present invention, when the supporting rotating ball 202 is in motion, Figure 3 and Figure 4As shown, at this time, the rotating gear 307 is meshed with the fixed rack 308, and the movement of the supporting rotating ball 202 causes the rotating gear 307 to start rotating. The rotation of the rotating gear 307 drives the spiral blade 305 to rotate synchronously through the linkage rotating cylinder 306. The trajectory of the spiral blade 305 causes the cross rod 301 to move downward while approaching the central axis of the circular plate 203, thereby driving the positioning rod 201 to approach the sound insulation blank 205 for precise positioning of the sound insulation blank 205. At the same time, as the cross rod 301 moves downward, it drives the positioning rod 201 downward, thereby avoiding interference with the blanking of the sound insulation blank 205. After the blanking operation of the sound insulation blank 205 is completed, as shown in FIG. Figure 6 As shown, at this time, as the supporting rotating ball 202 circulates, the rotating gear 307 is driven to engage with the reset rack 309, thereby driving the rotating gear 307 to reverse and reset, thereby achieving the purpose of automatically performing cyclic detection on the sound insulation blank 205.

[0051] like Figure 5 and Figure 7 As shown, as another preferred embodiment of the present invention, the follower mechanism 4 includes two rotating short rods 401 installed on the mounting plate 101, each rotating short rod 401 is rotatably installed on the connecting rod 402, the other end of the connecting rod 402 is connected to the circular plate rod 403, the other end of the circular plate rod 403 is connected to the circular plate 203, two tension springs 404 are fixedly installed on the surface of the circular plate rod 403, and two L-shaped connecting rods 410 are fixedly installed on the surface of the detection table 103, and the other end of each L-shaped connecting rod 410 is fixedly installed with a landslide plate 405, and the surface of the landslide plate 405 is provided with a first straight slope 406, a pulling slope 407, a second straight slope 408 and a reset slope 409 that cooperate with the rotating short rod 401 and are smoothly connected in sequence.

[0052] In practical application of the embodiment of the present invention, when the supporting rotating ball 202 is in motion, Figure 7As shown, the rotating short rod 401 moves along the first straight slope 406 to the pulling slope 407. The track of the pulling slope 407 drives the rotating short rod 401 downward, and then drives the circular plate 203 downward through the connecting rod 402 and the circular plate rod 403. At this time, the circular plate 203 drives the sound insulation blank 205 downward through the supporting rotating ball 202. After the sound insulation blank 205 is precisely positioned, it moves downward so that the sound insulation blank 205 falls on the rectangular sealing block 204, thereby completing the automatic positioning of the sound insulation blank 205. It should be noted here that When the rotating short rod 401 contacts the pulling slope 407, the rotating gear 307 and the fixed rack 308 are synchronously contacted and meshed. Therefore, the sound insulation blank 205 and the positioning round rod 201 are synchronously lowered, thereby ensuring the consistency of movement. After the sound insulation blank 205 is inspected, the rotating short rod 401 and the reset slope 409 cooperate to reset the rotating short rod 401 under the action of the tension spring 404. At this time, the supporting rotating ball 202 moves upward to lift the sound insulation blank 205, thereby facilitating the subsequent sorting operation of the sound insulation blank 205.

[0053] like Figure 2 、 Figure 7 and Figure 11As shown, as another preferred embodiment of the present invention, the swing mechanism 5 includes two T-shaped pillars 501 installed on the mounting plate 101, and the surface of each T-shaped pillar 501 is coaxially slidably installed with an electromagnet 502, the surface of the electromagnet 502 is connected to the permanent magnet 503 by an extrusion spring 504, and the permanent magnet 503 is fixedly installed on the T-shaped pillar 501, and the surface of the electromagnet 502 is fixedly installed with a sliding column 505, which passes through the T-shaped pillar 501 and is slidably connected to the T-shaped pillar 501, and the other end of the sliding column 505 is rotatably installed with a slide ball 506, and two arc slot blocks 507 are fixedly installed on the surface of the mounting plate 101, and the surface of each arc slot block 507 is provided with an upper slide 508, an inclined slide 509 and a lower slide 510 that cooperate with the slide ball 506 and are smoothly connected in sequence, and the T-shaped pillar 501 is fixedly installed on the swing rod 511. On the surface, the other end of the swing rod 511 is fixedly mounted on the linkage cylinder 512, the linkage cylinder 512 is rotatably connected to the ball head rod 513, and the linkage cylinder 512 is connected to the circulation ball rod 514 through two swing springs 515, the circulation ball rod 514 slides in cooperation with the circulation groove 102, the sliding block 303 is slidably connected to the inner wall of the linkage cylinder 512, the other end of the reset spring 304 is connected to the inner wall of the linkage cylinder 512, the linkage rotating cylinder 306 is rotatably connected to the linkage cylinder 512, a linear groove is provided inside the linkage cylinder 512 that cooperates with the cross rod 301, the round plate rod 403 passes through the linkage cylinder 512 and is slidably connected to the linkage cylinder 512, the other end of the tension spring 404 is connected to the inner wall of the linkage cylinder 512, the sounder 106 is fixedly mounted on the inner wall of the linkage cylinder 512, and the electromagnetic properties of the electromagnet 502 are different from the magnetic properties of the permanent magnet 503.

[0054] In actual application of the embodiment of the present invention, after the sound insulation blank 205 is inspected by the inspection station 103, if the sound insulation blank 205 is a qualified product, Figure 7 and Figure 11 As shown, at this time, the signal of the detection feedback device on the detection platform 103 makes the electromagnet 502 energized and magnetic. After the electromagnet 502 is magnetized, it is attracted by the permanent magnet 503, causing the electromagnet 502 to move toward a position close to the permanent magnet 503. At this time, the electromagnet 502 drives the sliding groove ball 506 to move away from the permanent magnet 503 through the sliding column 505, as shown in FIG. Figure 2As shown, as the supporting rotating ball 202 circulates, the chute ball 506 moves through the upper chute 508 to the inclined chute 509. Since the chute ball 506 cannot move downward, it is driven by the trajectory of the inclined chute 509 to tilt the chute ball 506, and then the linkage cylinder 512 is tilted via the swing rod 511. Since the moving mechanism 3 and the follower mechanism 4 have been freed from the internal limit of their own mechanisms, there is no movement interference, and the supporting rotating ball 202 is driven to tilt toward the quality slope 104. At this time, the sound insulation blank 205, under the action of gravity, passes through the guide mechanism 6 and the quality slope 104 and falls onto the conveyor belt for qualified products. Conversely, if the sound insulation blank 205 is unqualified, the electromagnet 502 at the symmetrical end is energized, causing the supporting rotating ball 202 to tilt toward the negative slope 105, thereby achieving the purpose of automatically sorting the sound insulation blanks 205.

[0055] like Figure 10 As shown, as another preferred embodiment of the present invention, the guide mechanism 6 includes a guide circular plate 601 fixedly mounted on the linkage cylinder 512, a plurality of guide balls 602 are rotatably mounted on the surface of the guide circular plate 601, and a plurality of linear grooves matching the positioning circular rod 201 are provided on the guide circular plate 601, a rectangular sealing block 204 is fixedly mounted on the surface of the guide circular plate 601, and a square hole is provided on the guide circular plate 601.

[0056] In actual application of the embodiment of the present invention, when the supporting rotating ball 202 is tilted, the sound insulation blank 205 slides along the supporting rotating ball 202 to the guide ball 602. The guide ball 602 guides the sound insulation blank 205 to fall on the positive product slope 104 or the negative product slope 105, thereby achieving the purpose of stable transportation and classification.

[0057] like Figure 2 and Figure 6 As shown, as another preferred embodiment of the present invention, the platform also includes a driving mechanism 7, which includes a driving motor 701 fixedly mounted on the mounting plate 101, and the output end of the driving motor 701 passes through the mounting plate 101 and is rotatably connected to the mounting plate 101, and the output end of the driving motor 701 is fixedly mounted with a main rotating wheel 702, and the surface of the main rotating wheel 702 is sleeved with a transmission chain 703, and the other end of the transmission chain 703 is sleeved on the driven rotating wheel 704, and the surface of the transmission chain 703 is fixedly connected to the circulating ball rod 514.

[0058] In practical application, the embodiment of the present invention is as follows: Figure 2 and Figure 6As shown, when the sound insulation blank 205 is inspected, the drive motor 701 starts to move. The movement of the drive motor 701 causes the transmission chain 703 to rotate cyclically through the transmission action of the gear chain, and then drives the supporting rotating ball 202 to rotate through the circulating ball rod 514, thereby achieving the purpose of cyclic inspection of the sound insulation blank 205.

[0059] The specific steps of the noise barrier performance test method include:

[0060] Step 1: The sound insulation blank 205 is placed on the supporting rotating ball 202 by an external grabbing device for preliminary rough positioning. At this time, the sound insulation blank 205 follows the supporting rotating ball 202 to perform a circular motion;

[0061] Step 2: During the cyclic motion, the sound insulation blank 205 is precisely positioned by the four positioning rods 201 , and the positioning rods 201 and the supporting rotating balls 202 are simultaneously lowered to avoid subsequent motion interference;

[0062] Step 3: When the sound insulation blank 205 is moved to the bottom of the detection platform 103, the detection feedback device on the detection platform 103 moves downward to press the sound insulation blank 205. At this time, the sound generator 106 plays a sound, and the data is recorded and fed back through the detection feedback device;

[0063] Step 4: The feedback signal drives the swing mechanism 5 at the corresponding end to move, so that the supporting rotating ball 202 tilts during the circular motion, and the sound insulation blanks 205 slide in different tilt directions to complete the classification.
