[0031] Please see Figures 1 to 3 A soundproof and shielded box, including

[0032] The box body 10 has a feed inlet 101 and a discharge outlet 102 on both sides;

[0033] Closing component 20 is installed inside the housing 10 and is used to open or close the inlet 101 and the outlet 102 as needed.

[0034] Mounting base 30; the mounting base 30 is installed inside the housing 10, and the upper part of the mounting base 30 is provided with a detection platform 301; the detection platform 301 is used to fix the product to be tested output from the feed port 101, and to output the product to be tested toward the discharge port 102 after the test is completed.

[0035] The input component 40 includes an input platform and a first drive unit. The input platform is mounted on the side of the detection platform 301 near the feed inlet 101 and is rotatably connected to the detection platform 301. The first drive unit is connected to the input platform and is used to drive the input platform to rotate relative to the detection platform 301 as needed, so that the input platform has a first working state and a second working state. In the first working state, the input platform is parallel to the detection platform 301 and is used to receive the product to be tested and to transport the product to be tested to the detection platform 301. In the second working state, the input platform rotates upward relative to the detection platform 301 so that the end of the input platform located at the feed inlet 101 is retracted into the housing 10.

[0036] The output component 50 includes an output platform and a second drive unit. The output platform is mounted on the side of the detection platform 301 near the discharge port 102 and is rotatably connected to the detection platform 301. The second drive unit is connected to the output platform and is used to drive the output platform to rotate relative to the detection platform 301 as needed, so that the input platform has a third working state and a fourth working state. In the third working state, the output platform is parallel to the detection platform 301, and its end away from the detection platform 301 is located at the discharge port 102, for outputting the product to be tested after detection in the detection platform 301 to the outside through the discharge port 102. In the fourth working state, the output platform rotates upward relative to the detection platform 301, so that the end of the output platform located at the discharge port 102 is retracted into the housing 10. The working principle of this embodiment is as follows: 1. Feeding stage: The first driving unit drives the input platform to rotate to the first working state. At this time, the input platform is parallel to the detection platform 301 and one end is located at the feed port 101. After the product to be tested is placed on the input platform, it is transported to the detection platform 301 by the input platform and fixed.

[0037] II. Testing Preparation Stage: The input platform rotates to the second working state under the action of the first drive unit and retracts into the housing 10; at the same time, the second drive unit drives the output platform to rotate to the fourth working state and retracts into the housing 10; the shut-off component 20 is started to completely close the inlet 101 and the outlet 102 to ensure that the housing 10 is sealed.

[0038] III. Testing Stage: A stable, interference-free environment is formed inside the sealed enclosure 10, and the testing platform 301 executes the preset testing process on the fixed product to be tested.

[0039] IV. Discharge Stage: After the test is completed, the closing component 20 opens the discharge port 102; the second drive unit drives the output platform to rotate to the third working state, with one end located at the discharge port 102 and parallel to the test platform 301; the test platform 301 releases the product to be tested, and the product is transported to the outside of the box 10 through the output platform to complete one test cycle.

[0040] In one specific embodiment, the closing component 20 includes a first shielding plate 201 installed above the feed inlet 101, a second shielding plate 202 installed above the discharge outlet 102, a first cylinder connected to the first shielding plate 201 for driving the first shielding plate 201 to move downward so that the first shielding plate 201 closes the feed inlet 101, and a second cylinder connected to the second shielding plate 202 for driving the second shielding plate 202 to move downward so that the second shielding plate 202 closes the discharge outlet 102. Specifically, a first cylinder is installed on both sides of the first shielding plate 201 and connected to it, used to drive it to move downwards to close the feed inlet 101; a second cylinder is installed on both sides of the second shielding plate 202 and connected to it, used to drive the second shielding plate 202 downwards to close the discharge outlet 102; in this embodiment, the setting of driving the first shielding plate 201 or the second shielding plate 202 by the first or second cylinder eliminates the need for manual pushing and pulling, and can be coordinated with the rotation of the input or output platform. Through the linkage of the control system (e.g., after the input platform transports the product to the testing platform 301, the first cylinder synchronously drives the first shielding plate 201 to close the feed port 101; after the test is completed, the second cylinder first drives the second shielding plate 202 to open, and the output platform automatically turns to the third working state to transport the product), no manual intervention is required for the closing or opening operation, reducing labor costs and operational errors. In addition, compared with traditional manual or motor gear transmission, the cylinder drive has a faster response speed (the single extension and retraction stroke of the cylinder can be completed within seconds), which greatly shortens the cycle of "feeding-sealing-testing-discharging" and meets the high-efficiency testing requirements of batch products.

[0041] In one specific embodiment, anti-pinch light curtains 103 are provided on both sides of the feed inlet 101 and the discharge outlet 102. The anti-pinch light curtains 103 can scan the opening area in real time to detect whether any human limbs (such as hands) are inserted. When the light curtain detects obstruction, it can immediately activate the first / second cylinder to stop the downward pressing action of the shielding plate, or pause the rotation and extension of the input / output platform, preventing hand injuries when the shielding plate closes or limb injuries when the platform moves. This fills the safety loophole of traditional soundproof shielded boxes where "opening operations are unprotected."

[0042] In one specific embodiment, the input platform includes a first mounting platform 401, a plurality of first feeding rollers 402 mounted side by side on the first mounting platform 401, and a first power module mounted on the first mounting platform 401 for driving the plurality of first feeding rollers 402 to rotate toward the detection platform 301 in the first working state; one end of the first mounting platform 401 near the detection platform 301 is rotatably connected to the detection platform 301; the first driving unit is connected to the first mounting platform 401 for driving the first mounting platform 401 to rotate relative to the detection platform 301.

[0043] Specifically, in this embodiment, the first power module includes a transmission wheel connected to the end of the first feeding roller 402, a transmission belt connected to adjacent transmission wheels to enable effective linkage of the various first feeding rollers 402, and a drive motor 403 installed below the first mounting platform 401 and connected to one of the first feeding rollers 402 for driving the rotation of that feeding roller. It should be noted that the transmission wheel and transmission belt are designed to synchronously link the rotation of other first feeding rollers 402 when the drive motor 403 drives the connected first feeding roller 402 to rotate. This is prior art and will not be elaborated upon here.

[0044] In one specific embodiment, a first sensor 404 for detecting whether a product to be tested exists on the first feeding roller 402 is provided above the end of the first mounting platform 401 away from the detection platform 301. Specifically, in this embodiment, the first sensor 404 is a photoelectric sensor. Further, the first driving unit includes a third cylinder 405 whose bottom is rotatably connected to the mounting base 30, and whose power output end is rotatably connected to the end of the first mounting platform 401 near the feed inlet 101.

[0045] In one specific embodiment, the output platform includes a second mounting platform 501, a plurality of second feeding rollers 502 mounted side-by-side on the second mounting platform 501, and a second power module mounted on the second mounting platform 501 for driving the plurality of second feeding rollers 502 to rotate toward the discharge port 102 in the third working state; one end of the second mounting platform 501 near the detection platform 301 is rotatably connected to the detection platform 301; the second drive unit is connected to the second mounting platform 501 for driving the second mounting platform 501 to rotate relative to the detection platform 301. Specifically, in this embodiment, the second power module has a similar structure to the first power module, which will not be described in detail here. Further, a second sensor 503 for detecting whether there is a product to be tested on the second feeding rollers 502 is provided above the end of the second mounting platform 501 away from the detection platform 301. Specifically, in this embodiment, the second sensor 503 is a photoelectric sensor. The second drive unit includes a fourth cylinder 504 whose bottom is rotatably connected to the mounting base 30 and whose power output end is rotatably connected to one end of the second mounting platform 501 near the discharge port 102.

[0046] In one specific embodiment, the detection platform 301 includes connecting plates 302 mounted on both sides above the mounting base 30, third feeding rollers 303 mounted side-by-side between the two connecting plates 302, and a third power module connected to multiple third feeding rollers 303 for driving each feeding roller to rotate synchronously. Above the connecting plates 302 are clamping cylinders 304 for clamping the product to be tested conveyed to the feeding rollers, and third sensors 305 for detecting whether a product to be tested exists above the third feeding rollers 303. Specifically, the third power module has the same structure as the first / second power modules, and will not be described in detail here. Specifically, in one specific embodiment, a microphone 105 for detection is provided inside the housing 10, and a controller 104 is provided on the upper part of the housing 10.

[0047] The working principle of this utility model is as follows: After the equipment is started, the feeding and discharging mode (such as forward and backward or backward and forward) is set by the controller 104, and the equipment enters the standby state. The product to be tested is placed on the first feeding roller 402 of the input component 40. After the first sensor 404 detects the product, the first power module drives the first feeding roller 402 to rotate. At the same time, the third cylinder 405 of the first drive unit drives the first mounting platform 401 to rotate to the first working state (parallel to the detection platform 301). The product is smoothly transported from the input platform to the third feeding roller 303 of the detection platform 301.

[0048] After the third sensor 305 detects the product, the third power module stops operating, and the clamping cylinder 304 on the connecting plate 302 extends to firmly clamp and position the product. Subsequently, the third cylinder 405 drives the first mounting platform 401 to rotate to the second working state (retracted into the housing 10), and the fourth cylinder 504 of the second drive unit drives the second mounting platform 501 to rotate to the fourth working state (retracted into the housing 10). The first cylinder drives the first shielding plate 201 to move downward to close the feed port 101, and the second cylinder drives the second shielding plate 202 to move downward to close the discharge port 102. The housing 10 forms a sealed environment, and the detection platform 301, in conjunction with the microphone 105 inside the housing 10, begins to execute the preset detection process.

[0049] After the test is completed, the controller 104 sends a signal, and the first and second cylinders drive the first shielding plate 201 and the second shielding plate 202 to move upwards to open the inlet and outlet. The fourth cylinder 504 drives the second mounting platform 501 to rotate to the third working state (parallel to the test platform 301), the clamping cylinder 304 retracts, the third power module drives the third feeding roller 303 to rotate, and at the same time the second power module drives the second feeding roller 502 to rotate. The product is conveyed to the outside of the box 10 through the output platform. After the second sensor 503 detects that the product has been completely output, the equipment automatically resets to the standby state, completing one complete test cycle.

[0050] If the anti-pinch light curtain 103 detects a limb obstructing the feed inlet 101 or the discharge outlet 102 area during the detection process, the controller 104 will immediately pause all operations. After the obstruction is removed, the equipment must be manually reset before it can be restarted to ensure operational safety.

[0051] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
