[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, 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 used to limit the present invention.

[0018] It can be understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0019] As Figure 1 and Figure 3 shown, in one embodiment, a sound insulation barrier performance test platform is proposed, and the platform includes: Main frame 1: including two mounting plates 101 provided on the main frame 1, each mounting plate 101 is provided with a circulation groove 102, a detection table 103 is fixedly installed on the mounting plate 101, a detection feedback device is installed on the detection table 103, a genuine product ramp 104 and a defective product ramp 105 are respectively and fixedly installed on the two mounting plates 101, a plurality of rolling balls are rotatably installed on both the genuine product ramp 104 and the defective product ramp 105, and a sound generator 106 installed on the mounting plate 101 is further included; Positioning mechanism 2: There are multiple ones and they are installed on the mounting plate 101. It includes four positioning round rods 201 installed on the mounting plate 101 for positioning the sound insulation blank 205, and also includes multiple supporting rotating balls 202 for supporting the sound insulation blank 205. The supporting rotating balls 202 are rotatably installed on the circular plate 203. It also includes a rectangular sealing block 204 installed on the mounting plate 101 for sealing the surface of the sound insulation blank 205; Moving mechanism 3: It is used to drive the positioning round rods 201 to position the sound insulation blank 205; Follow-up mechanism 4: It is used to place the positioned sound insulation blank 205 on the rectangular sealing block 204; Swinging mechanism 5: It is used to drive the circular plate 203 to swing for discharging the sound insulation blank 205; Guiding mechanism 6: It is used to stably guide the discharged sound insulation blank 205.

[0020] When the embodiment of the present invention is actually applied, when performing the test operation of the sound insulation blank 205, as Figure 1 and Figure 3 shown, at this time, the sound insulation blank 205 is placed on the supporting rotating balls 202 through an external grasping device. Under the action of an external drive, the supporting rotating balls 202 start to move in a cycle. At this time, with the movement of the supporting rotating balls 202, through the action of the moving mechanism 3, the four positioning round rods 201 approach the sound insulation blank 205 and push it to the center, so as to achieve the purpose of automatically and precisely positioning the sound insulation blank 205. And the positioning round rods 201 move downward synchronously when pushing the sound insulation blank 205. The downward movement of the positioning round rods 201 avoids movement interference during the later discharging of the sound insulation blank 205. During the movement of the positioning round rods 201, through the action of the follow-up mechanism 4, the circular plate 203 is driven to move downward synchronously, and then the sound insulation blank 205 is driven to move downward through the supporting rotating balls 202. At this time, when the sound insulation blank 205 is precisely positioned, the sound insulation blank 205 drops onto the surface of the rectangular sealing block 204, as Figure 1As shown, when the sound insulation blank 205 comes below the detection table 103 with the movement of the supporting rotating ball 202, the detection feedback device on the detection table 103 moves downward and presses tightly on the sound insulation blank 205. Through the pressing force, the sound insulation blank 205 is attached and sealed to the rectangular sealing block 204. At this time, the sound generator 106 starts to operate. By emitting a test sound, the detection feedback device receives the sound and judges the intensity of the sound. The signal of 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 operates. After the detection table 103 resets, the supporting rotating ball 202 continues to move. Under the action of the swing mechanism 5, the supporting rotating ball 202 tilts towards the end of the genuine product slope 104. At this time, the sound insulation blank 205 slides down along the supporting rotating ball 202 under the action of gravity to the guiding mechanism 6, and then slides down to the genuine product slope 104 through the guiding mechanism 6, thus achieving the purpose of automatically classifying the sound insulation blank 205.

[0021] As 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 bar 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 bar 301. The other end of the compression spring 302 is connected to a sliding block 303. The cross bar 301 is slidably connected to the sliding block 303. A return spring 304 is also fixedly installed on the surface of the sliding block 303. An arc-shaped opening is formed on the surface of the cross bar 301. It further includes a spiral blade 305 that cooperates with the arc-shaped opening on the cross bar 301. The spiral blade 305 is fixedly installed on the inner wall of the linkage rotating cylinder 306. The track radius of the spiral blade 305 gradually decreases. A rotating gear 307 is coaxially and fixedly installed on the surface of the linkage rotating cylinder 306. A fixed rack 308 and a return rack 309 that cooperate with the rotating gear 307 are fixedly installed on the surface of the mounting plate 101.

[0022] In the actual application of the embodiment of the present invention, when the supporting rotating ball 202 is moving, as Figure 3 and Figure 4As shown, at this time, the rotating gear 307 meshes with the fixed rack 308. 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. Due to the trajectory effect of the spiral blade 305, the cross bar 301 moves downward while approaching the central axis of the circular plate 203, thereby driving the positioning round rod 201 to approach the sound insulation blank 205 to perform precise positioning on the sound insulation blank 205. At the same time, as the cross bar 301 drives the positioning round rod 201 to move downward, it avoids interfering with the blanking of the sound insulation blank 205. When the blanking operation of the sound insulation blank 205 is completed, as Figure 6 shown, at this time, as the supporting rotating ball 202 circulates, it drives the rotating gear 307 to mesh with the reset rack 309, thereby driving the rotating gear 307 to reverse and reset, so as to achieve the purpose of automatically detecting the sound insulation blank 205 in a cycle.

[0023] As Figure 5 and Figure 7 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. Two L-shaped connecting rods 410 are fixedly installed on the surface of the inspection table 103. The other end of each L-shaped connecting rod 410 is fixedly installed with a landslide plate 405. 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.

[0024] In the actual application of the embodiment of the present invention, when the supporting rotating ball 202 is in motion, as Figure 7As shown, at this time, the rotating short rod 401 moves to the pulling slope 407 through the first straight slope 406. Driven by the trajectory of the pulling slope 407, the rotating short rod 401 moves downward. Then, through the connecting rod 402 and the circular plate rod 403, the circular plate 203 is driven to move downward. At this time, the circular plate 203 drives the sound insulation blank 205 to move downward through the supporting rotating ball 202. After fine positioning, the sound insulation blank 205 moves downward and lands on the rectangular sealing block 204, thus achieving the purpose of automatically positioning 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 contact and mesh synchronously. Therefore, the sound insulation blank 205 and the positioning round rod 201 descend synchronously, ensuring the consistency of movement. After the inspection of the sound insulation blank 205 is completed, through the cooperation of the rotating short rod 401 and the reset slope 409, the rotating short rod 401 is reset 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, facilitating the subsequent classification operation of the sound insulation blank 205.

[0025] As Figure 2 , Figure 7 and Figure 11As shown, as another preferred embodiment of the present invention, the swing mechanism 5 includes two T-shaped column rods 501 mounted on the mounting plate 101. A through electromagnet 502 is coaxially and slidably mounted on the surface of each T-shaped column rod 501. The surface of the through electromagnet 502 is connected to a permanent magnet 503 through a compression spring 504. The permanent magnet 503 is fixedly mounted on the T-shaped column rod 501. A sliding column 505 is fixedly mounted on the surface of the through electromagnet 502. The sliding column 505 penetrates through the T-shaped column rod 501 and is slidably connected to the T-shaped column rod 501. The other end of the sliding column 505 is rotatably mounted with a chute ball 506. Two arc chute blocks 507 are fixedly mounted on the surface of the mounting plate 101. An upper chute 508, an inclined chute 509 and a lower chute 510 which are matched with the chute ball 506 and are smoothly connected in sequence are formed on the surface of each arc chute block 507. The T-shaped column rod 501 is fixedly mounted on the surface of the swing rod 511. 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 circulating ball rod 514 through two swing springs 515. The circulating ball rod 514 is slidably matched with the circulating groove 102. The sliding block 303 is slidably connected to the inner wall of the linkage cylinder 512. The other end of the return 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 matched with the cross rod 301 is formed inside the linkage cylinder 512. The circular plate rod 403 penetrates 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 sound generator 106 is fixedly mounted on the inner wall of the linkage cylinder 512. The magnetic property of the through electromagnet 502 is different from that of the permanent magnet 503.

[0026] In the actual application of the embodiment of the present invention, when the sound insulation blank 205 is detected by the detection table 103, if the sound insulation blank 205 is a qualified product, as Figure 7 and Figure 11 shown, at this time, the through electromagnet 502 is energized and magnetized through the signal of the detection feedback device on the detection table 103. After the through electromagnet 502 is magnetized, it is attracted by the permanent magnet 503, so that the through electromagnet 502 moves towards the position close to the permanent magnet 503. At this time, the through electromagnet 502 drives the chute ball 506 to move away from the permanent magnet 503 through the sliding column 505, as Figure 2As shown, with the cyclic movement of the supporting rotating ball 202, at this time, the chute ball 506 moves to the inclined chute 509 through the upper chute 508. Since the chute ball 506 cannot move downward, under the action of the trajectory of the inclined chute 509, the chute ball 506 is driven to tilt, and then the linkage cylinder 512 is driven to tilt through the swing rod 511. Since the moving mechanism 3 and the follower mechanism 4 have been disengaged from the limits of their own internal mechanisms, there will be no movement interference, and then the supporting rotating ball 202 is driven to tilt in the direction of the genuine product slope 104. At this time, the sound insulation blank 205 falls on the conveyor belt of the qualified products under the action of gravity through the guiding mechanism 6 and the genuine product slope 104. On the contrary, if it is unqualified, the electromagnet 502 at the symmetric end is energized, causing the supporting rotating ball 202 to tilt towards the position of the defective product slope 105, so as to achieve the purpose of automatically classifying the sound insulation blank 205.

[0027] As Figure 10 shown, as another preferred embodiment of the present invention, the guiding mechanism 6 includes a guiding circular plate 601 fixedly installed on the linkage cylinder 512. A plurality of guiding spherical balls 602 are rotatably installed on the surface of the guiding circular plate 601, and a plurality of linear grooves cooperating with the positioning circular rod 201 are provided on the guiding circular plate 601. The rectangular sealing block 204 is fixedly installed on the surface of the guiding circular plate 601, and a square hole is provided on the guiding circular plate 601.

[0028] In the actual application of the embodiment of the present invention, when the supporting rotating ball 202 tilts, at this time, the sound insulation blank 205 slides along the supporting rotating ball 202 to the guiding spherical balls 602, and through the guiding action of the guiding spherical balls 602, the sound insulation blank 205 falls on the genuine product slope 104 or the defective product slope 105, so as to achieve the purpose of stable conveying and classification.

[0029] As Figure 2 and Figure 6 shown, as another preferred embodiment of the present invention, the platform further includes a driving mechanism 7. The driving mechanism 7 includes a driving motor 701 fixedly installed on the mounting plate 101. The output end of the driving motor 701 penetrates through the mounting plate 101 and is rotatably connected to the mounting plate 101. A main rotating wheel 702 is fixedly installed at the output end of the driving motor 701. A transmission chain 703 is sleeved on the surface of the main rotating wheel 702. 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.

[0030] In the actual application of the embodiment of the present invention, as Figure 2 and Figure 6As shown in the figure, when the sound insulation blank 205 is detected, the driving motor 701 starts to move at this time. The movement of the driving motor 701 causes the transmission chain 703 to rotate in a cycle through the transmission of the gear chain, and then drives the support rotating ball 202 to rotate through the circulating ball rod 514, so as to achieve the purpose of circularly detecting the sound insulation blank 205.

[0031] The specific steps of this sound insulation barrier performance test method include: Step 1: Place the sound insulation blank 205 on the support rotating ball 202 through an external grasping device for preliminary rough positioning. At this time, the sound insulation blank 205 follows the support rotating ball 202 to move in a cycle; Step 2: During the cyclic movement, the sound insulation blank 205 is accurately positioned by four positioning round rods 201. At the same time, the positioning round rods 201 and the support rotating ball 202 descend synchronously to avoid subsequent movement interference; Step 3: When moving below the detection table 103, the detection feedback device on the detection table 103 moves downward to press the sound insulation blank 205. At this time, the sound generator 106 plays sound, and data is recorded and fed back through the detection feedback device; Step 4: Drive the swing mechanism 5 at the corresponding end to move through the feedback signal, so that the support rotating ball 202 tilts during the cyclic movement, and the sound insulation blank 205 slides off through different tilting directions to complete classification.

[0032] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
