Description

Technical Field

[0001] This invention relates to the field of down detection technology, and more particularly to a single-station horizontal oscillator. Background Technology

[0002] The waterproof performance of down is one of the core indicators for measuring the quality of down products. It directly affects the warmth retention, service life and user experience of down. Therefore, accurate testing of the waterproof performance of down is an essential part of the production and testing process. At present, the waterproof performance of down is mostly tested by shaking. That is, the down sample and distilled water are placed in a volumetric flask, shaken, and then the settling state of the down is observed to determine its waterproof performance. In the existing technology, this test usually relies on a horizontal oscillator with a simple sample fixing device. The common practice is to use an oscillating table with a clamp. The general clamp needs to be manually tightened, which reduces the testing efficiency and is prone to loosening under long-term high-frequency oscillation. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides the following technical solution: A single-station horizontal oscillator, including: The main body of the oscillator; The placement assembly includes a placement frame mounted on the main body of the vibrator via an output shaft, a placement cavity opened in the placement frame for accommodating a test volumetric flask, a pressing member symmetrically arranged vertically within the placement frame, a clamping member arranged horizontally within the placement frame and driven by the pressing member, and a release member disposed on the placement frame for driving the clamping member to reset. A visual sensor is mounted on the main body of the oscillator, with its detection end facing the placement cavity; The pressing member and the clamping member are connected by a wedge block, which allows the vertical movement of the pressing member to be converted into the horizontal clamping movement of the clamping member. Operating the releasing member can drive the clamping member to horizontally reset and release the test volume bottle.

[0004] As an improvement to the above technical solution, the pressing component includes a push plate that is movably inserted into the mounting groove and a slot formed on the push plate. The inclined block is integrally formed and disposed on the push plate and located at the slot position. A spring is provided between the bottom of the push plate and the mounting groove.

[0005] As an improvement to the above technical solution, the clamping member includes a connecting rod movably disposed within the placement frame and opposite to the direction of movement of the push plate, and a clamping plate perpendicular to the connecting rod. The connecting rod has a slot that cooperates with the inclined block. The pressing of the push plate generates a horizontal thrust on the connecting rod through the inclined block.

[0006] As an improvement to the above technical solution, the placement frame is provided with a sliding groove for the connecting rod to move. The placement frame has an assembly groove that is perpendicular to and connected to the sliding groove. The release component includes two sets of abutment rods that are slidably disposed in the sliding groove. The end of the abutment rod away from the connecting rod extends into the assembly groove. A wedge block is fixedly connected to the end of the abutment rod that extends into the assembly groove. A spring is wound around the surface of the abutment rod and located in the assembly groove. A pushing part is provided between the two sets of wedge blocks.

[0007] As an improvement to the above technical solution, the pushing part includes a movable rod that is movably inserted into the side wall of the placement frame. One end of the movable rod located inside the assembly groove is fixedly connected to a conical head that matches the wedge block. A spring is wound around the surface of the movable rod and outside the placement frame.

[0008] As an improvement to the above technical solution, two sets of symmetrically distributed limiting blocks are integrally formed on the surface of the movable rod and inside the placement frame. A moving groove adapted to the movable rod is opened in the placement frame. A connecting groove for axial movement of the limiting blocks is opened in the placement frame at the position of the moving groove. A limiting groove communicating with the connecting groove and for limiting the limiting blocks to be positioned is opened in the placement frame.

[0009] As an improvement to the above technical solution, it also includes two sets of fixing rods, which are symmetrically distributed on both sides of the placement cavity.

[0010] As an improvement to the above technical solution, a supplementary light is installed on the side of the placement rack away from the visual sensor, and the illumination direction of the supplementary light is towards the placement cavity.

[0011] The beneficial effects of this invention are: By using the weight of the volumetric flask itself as the driving force, the inclined block automatically converts it into a horizontal clamping force, achieving "locking upon placement". This process requires no external power or manual adjustment, making operation extremely simple. It also fundamentally ensures that the clamping force is consistent for each test, eliminating human error. There is no need to manually twist or adjust the clamps; the flask automatically locks after filling, greatly simplifying the operation process and improving testing efficiency.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this invention clearer, the 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 merely illustrative and not intended to limit the invention.

[0015] A single-station horizontal oscillator, comprising: oscillator body 10; The placement assembly 20 includes a placement frame 21 mounted on the vibrator body 10 via an output shaft, a placement cavity 22 opened in the placement frame 21 for accommodating a test volumetric flask, a pressing member symmetrically arranged vertically within the placement frame 21, a clamping member arranged horizontally within the placement frame 21 and driven by the pressing member, and a release member disposed on the placement frame 21 for driving the clamping member to reset. A visual sensor 30 is disposed on the main body of the oscillator, with its detection end facing the placement cavity; The pressing member and the clamping member are connected by a wedge block 241, so that the vertical movement of the pressing member can be converted into the horizontal clamping movement of the clamping member. Operating the releasing member can drive the clamping member to horizontally reset and release the test volume bottle. Specifically, during the down waterproof performance test, two-thirds of a transparent volumetric flask is filled with distilled water, followed by a quantitative amount of down sample to be tested. The flask cap is tightened and placed into the placement chamber of the rack. Due to the flask's weight, its bottom contacts and acts on the upper surface of the pressing component, applying a downward vertical gravitational load. This load drives a downward vertical force on the pressing component, causing it to move vertically downward along the inside of the rack 21. Because the pressing component and the clamping component are mechanically linked via a wedge block 241, the inclined surface structure of the wedge block 241 converts the vertical trajectory of the pressing component, pushing the clamping component to move horizontally along the inside of the rack. The two symmetrically distributed clamping components synchronously move towards the center of the placement chamber until the clamping ends of the clamping components are tightly fitted with both ends of the test volumetric flask, completing the clamping and fixing of the test volumetric flask and ensuring that the volumetric flask remains stationary during vibration. The shaker body 10 is then activated, causing its oscillating components to drive the placement component 20 to reciprocate horizontally via the output shaft. The placement component 20 drives the volumetric flask to oscillate. During this process, the down inside the flask is fully dispersed on the water surface due to the oscillation. If the down surface has good hydrophobicity, water will have difficulty penetrating the fibers, and the down will remain floating on the water surface. Conversely, if the waterproof performance is poor, the down will absorb water and sink. At the same time, the vision sensor 30 continuously acquires images of the placement cavity 22 area to monitor the settling state of the down in the water in real time. When the oscillation process ends and the test volumetric flask needs to be removed, the operator triggers the release component. The release component overcomes the locking effect of the inclined block 241 and drives the clamping component to move in the opposite direction in the horizontal direction, causing it to detach from the clamping of the volumetric flask, thereby achieving a quick and convenient release operation, which is convenient for picking up and putting down samples. The vision sensor used is IV4-G500CA.

[0016] In one embodiment, the pressing member includes a push plate 24 movably inserted into the mounting groove 211 and a slot 242 formed on the push plate 24. The inclined block 241 is integrally formed on the push plate 24 and located at the slot 242. A spring 25 is provided between the bottom of the push plate 24 and the mounting groove 211. The clamping member includes a connecting rod 231 movably disposed in the placement frame 21 and opposite to the direction of movement of the push plate 24, and a clamping plate 23 perpendicular to the connecting rod 231. The connecting rod 231 has a slot that cooperates with the inclined block 241. The pressing of the push plate 24 generates a horizontal thrust on the connecting rod 231 through the inclined block 241. When the volumetric flask is not placed, spring 25 lifts the push plate 24 to its initial high position. After the volumetric flask is placed into the placement cavity 22, its own weight presses down on the push plate 24, causing it to move downward against the elastic force of spring 25. When the push plate 24 moves downward under the action of the volumetric flask's weight, the integrally formed inclined block 241 descends accordingly. The inclined block 241 exerts force through the slot of the connecting rod 231 and along the inclined surface of the inclined block 241, thereby applying a pushing force to the connecting rod 231 and driving the entire clamping component to move horizontally. The symmetrically distributed clamping components move synchronously, so that the clamping plate 23 adheres to the volumetric flask from both ends, achieving stable and non-eccentric clamping and fixing, effectively preventing the flask from shaking or falling off during vibration. This structure uses the volumetric flask's own weight as the clamping driving force, requiring no additional energy, and achieves an adaptive operation of "clamping as soon as it is placed". The inner side of the clamping plate 23 is bonded with a flexible buffer pad, such as silicone, to increase friction and protect the flask.

[0017] In one embodiment, the placement frame 21 has a sliding groove for the connecting rod 231 to move. The placement frame 21 also has an assembly groove that is perpendicular to and communicates with the sliding groove. The release component includes two sets of abutment rods 26 slidably disposed within the sliding groove. One end of the abutment rod 26 away from the connecting rod 231 extends into the assembly groove. A wedge block 261 is fixedly connected to one end of the abutment rod 26 extending into the assembly groove. A second spring 262 is wound around the surface of the abutment rod 26 and within the assembly groove. A pushing part is provided between the two sets of wedge blocks 261. The pushing part includes a movable rod 271 movably inserted into the side wall of the placement frame 21. A conical head 27 adapted to the wedge block 261 is fixedly connected to one end of the movable rod 271 within the assembly groove. A third spring 273 is wound around the surface of the movable rod 271 and outside the placement frame 21. When the test is complete and the volumetric flask needs to be released, the operator presses the movable rod 271 (located at the operating end outside the placement rack 21) inward. The movable rod 271 overcomes the elastic force of the spring 273 and moves into the assembly slot, driving the conical head 27 to advance synchronously. After the conical head 27 enters between the two sets of wedge blocks 261, its conical inclined surface contacts the inner inclined surface of the wedge block 261, generating an outward horizontal component force. This component force pushes the two sets of wedge blocks 261, causing the abutment rod 26 to slide outward. As the abutting rod 26 comes into contact with the connecting rod 231, it pushes the connecting rod 231 outward, causing the clamping plate 23 to detach from the outer wall of the volumetric flask, completing the horizontal reset and release action of the clamping component. After the release operation is completed, the operator releases the movable rod 271, and the spring 3 273 pushes the movable rod 271 and the conical head 27 outward to retract, disengaging from the space between the wedge blocks 261. At the same time, the spring 262 pulls the wedge blocks 261 and the abutting rod 26 back to their initial positions.

[0018] In one embodiment, two sets of symmetrically distributed limiting blocks 272 are integrally formed on the surface of the movable rod 271 and inside the placement frame 21. The placement frame 21 has a moving groove 212 adapted to the movable rod 271. A communicating groove 2121 for axial movement of the limiting blocks 272 is provided within the placement frame 21 and at the position of the moving groove 212. A limiting groove 2122 communicating with the communicating groove 2121 and limiting the limiting blocks 272 is also provided within the placement frame 21. Initially, the limiting blocks are located within the limiting groove 2122. At this time, the sidewall of the limiting groove 2122 forms a circumferential constraint on the limiting blocks 272, preventing the movable rod 271 from being accidentally pressed axially, effectively preventing accidental triggering under equipment vibration. When it is necessary to release the volumetric flask, the operator first slightly rotates the movable rod 271. The limiting block 272 rotates circumferentially out of the limiting groove 2122 and into the communicating groove 2121 connected to it. This rotation releases the circumferential lock, allowing the movable rod 271 to gain axial freedom of movement. After unlocking, the operator pushes the movable rod 271 axially inward, causing it to drive the conical head 27 to push the two sets of wedge blocks 261 outward. Then, through the abutment rod 26, the connecting rod 231 and the clamping plate 23 are driven to reset outward, thereby releasing the volumetric flask. After release, the movable rod 271 is released, and under the elastic force of the spring 273, the movable rod 271 automatically retracts outward to the initial position. At this time, the operator can rotate the movable rod 271 again to realign the limiting block 272 and lock it into the limiting groove 2122, restoring the locked state and ensuring that the release mechanism will not loosen or malfunction during the next oscillation of the equipment.

[0019] In one embodiment, two sets of fixing rods 28 are also included. The two sets of fixing rods 28 are symmetrically distributed on both sides of the placement cavity 22. Rubber pads are sleeved on the surface of the fixing rods 28. When the volumetric flask is placed into the placement cavity 22, the flask body naturally abuts against the two sets of fixing rods 28. The weight of the flask presses down on the pushing plate 24, which drives the inclined block 241 to push the connecting rod 231, so that the clamping plate 23 presses the flask body from the opposite side. The fixing rods 28 and the clamping plate 23 together form a four-point constraint to ensure that the flask body does not shake during horizontal oscillation.

[0020] In one embodiment, a supplementary light 29 is installed on the side of the placement rack 21 away from the visual sensor 30. The illumination direction of the supplementary light 29 is towards the placement cavity 22. The supplementary light 29 is located on the side opposite to the visual sensor 30. After the light passes through the transparent volumetric bottle, it can clearly outline the contour and distribution of the down, thus improving the image contrast.

[0021] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
