DETAILED DESCRIPTION

[0034] Example one: please refer to Figures 1-4 , the application provides a technical solution: a kind of assembly tooling applied to immune chromatography reagent strip large plate, including bottom plate 1 and electric rotating table 5, bottom plate 1 top is fixedly connected with numerical control mechanical arm 6, electric rotating table 5 top is provided with disc 2, disc 2 top is provided with large plate clamping mechanism 3;

[0035] Large plate clamping mechanism 3 includes:

[0036] Sliding slide plate 301, sliding slide plate 301 is square plate structure, sliding slide plate 301 top is fixedly connected with clamping block 302, sliding slide plate 301 bottom is contacted with sliding bar 304, sliding bar 304 bottom is fixedly connected with disc 2 top, sliding slide plate 301 top is placed with PVC bottom plate 303, PVC bottom plate 303 outer wall and clamping block 302 one side contact, sliding slide plate 301 is used to fixed with the role of clamping PVC bottom plate 303;

[0037] The fixed baffle 310 is a rectangular plate structure, the bottom of the fixed baffle 310 is fixedly connected with the top of the disc 2, a limiting groove 311 is formed in the inner wall of the fixed baffle 310, the limiting groove 311 is used for embedding the sliding sliding plate 301 and the clamping block 302 to play a blocking role, and the shape of the limiting groove 311 and the sliding sliding plate 301 is matched to prevent the problem of skew caused by impact when blocking, the bottom of the sliding sliding plate 301 is slidably connected with the surface of the disc 2 through a sliding strip 304, and the fixed baffle 310 is used for limiting the sliding sliding plate 301;

[0038] In use, the PVC bottom plate 303 is clamped by the numerical control mechanical arm 6 and then placed on the sliding sliding plate 301 on the disc 2, then the disc 2 is controlled to rotate by a certain angle by the electric rotating table 5, and after rotation, the numerical control mechanical arm 6 on the two sides is used for placing the subsequent cushion layer on the sliding sliding plate 301, so that the disc 2 is continuously intermittently rotated, and the numerical control mechanical arm 6 is used for pipeline type stacking and assembling work.

[0039] Embodiment two: please refer to Figures 1-9 On the basis of the embodiment one, the application provides a technical scheme that one side of the sliding sliding plate 301 is fixedly connected with an elastic rope 306, one end of the elastic rope 306 is fixedly connected with a fixed plate 305, and the bottom of the fixed plate 305 is fixedly connected with the top of the disc 2.

[0040] One side of the fixed plate 305 is fixedly connected with an extension sleeve 307, and one end of the extension sleeve 307 is fixedly connected with one side of the sliding sliding plate 301.

[0041] The outer wall of the fixed block 308 is fixedly connected with a backing plate 309, and one side of the backing plate 309 is in contact with one side of the sliding sliding plate 301.

[0042] When the disc 2 rotates, the reagent strip stack placed on the PVC base plate 303 by the numerical control mechanical arm 6 is easily extruded and warped by the outward centrifugal force when the disc 2 rotates, and is pressed against the clamping block 302 at the outer ring position of the disc 2, causing the cushion layer on the PVC base plate 303 to deform and warp. When the disc 2 rotates, the sliding slide plate 301 loaded with the PVC base plate 303 and the clamping block 302 will slide outward along the centrifugal force to the outer ring of the disc 2. The sliding slide plate 301 slides on the sliding strip 304, so that the clamping block 302 on the sliding slide plate 301 slides outward together with the PVC base plate 303, relieving the extrusion force between the clamping block 302 and the cushion layer on the PVC base plate 303 when the cushion layer is subjected to the outward centrifugal force, avoiding the problem of the cushion layer on the PVC base plate 303 sliding and warping upward on the clamping block 302. After the sliding slide plate 301 slides outward, the sliding slide plate 301 will stretch the elastic rope 306. One end of the elastic rope 306 is fixed by the fixed plate 305, so that the elastic rope 306 will be pulled back to its original position by the elastic force after it is stretched. Then the sliding slide plate 301 will be pulled back to the cushion plate 309 by the elastic rope 306 and be stopped by the cushion plate 309, thereby completing the homing;

[0043] The fixed baffle 310 and the limiting groove 311 formed in the inner wall of the fixed baffle 310 are used to limit the sliding slide plate 301 after it is thrown out and abut against the inner wall of the limiting groove 311, thereby limiting the distance that the sliding slide plate 301 is thrown out when the disc 2 rotates too fast. This ensures the uniformity of the time and speed of the sliding slide plate 301 returning to its original position, which is beneficial to the subsequent assembly work of the numerical control mechanical arm 6;

[0044] When the sliding slide plate 301 is pulled back and abuts against the cushion plate 309 and produces a certain collision vibration, the soft material of the cushion plate 309 can reduce the vibration of the sliding slide plate 301. The residual vibration of the sliding slide plate 301 can be beneficial to the stable placement of various cushion layers placed above the PVC base plate 303. The vibration of the PVC base plate 303 driven by the sliding slide plate 301 can vibrate and flatten each type of cushion layer placed on the sliding slide plate 301 by the numerical control mechanical arm 6, preventing the occurrence of deviation during placement and causing the cushion layer to warp and tilt;

[0045] When the disc 2 rotates to drive the sliding slide plate 301 and the clamping block 302 and the PVC bottom plate 303 to slide outward, the sliding of the sliding slide plate 301 pulls the telescopic sleeve 307 to stretch, and when the telescopic sleeve 307 stretches, the space inside the telescopic sleeve 307 expands to form negative pressure, and the telescopic sleeve 307 is in communication with the air extraction groove 403 above the sliding slide plate 301 through the sliding slide plate 301, so that when the negative pressure is formed inside the telescopic sleeve 307, air is sucked into the telescopic sleeve 307 through the air extraction groove 403, and the air extraction groove 403 is provided with an air inlet one-way valve, so that the air extraction groove 403 can only intake air from above and cannot exhaust air outward, so that when the air above the sliding slide plate 301 is all sucked into the telescopic sleeve 307 through the air extraction groove 403, an air flow path from top to bottom is formed, so that when the disc 2 rotates, the air flow from top to bottom can press the reagent strip cushion layer which is prone to be lifted on one side of the clamping block 302 as much as possible, so as to reduce the occurrence of edge lifting and skewing in the assembly process, and the stability of the immunoassay reagent strip assembly is maintained.

[0046] Embodiment three: please refer to Figures 1-11 On the basis of the embodiments one and two, the application provides a technical solution: the telescopic sleeve 307 is provided with a buffer mechanism 4, the buffer mechanism 4 comprises a one-way valve air hole 401, the one-way valve air hole 401 is arranged on the outer wall of the telescopic sleeve 307, and the inside of the telescopic sleeve 307 is in communication with the inside of the one-way valve air hole 401.

[0047] The inside of the telescopic sleeve 307 is in communication with the inside of the one-way valve air hole 401, and the inside of the telescopic sleeve 307 is in communication with the outside of the telescopic sleeve 307 through the one-way valve air hole 401.

[0048] The top of the sliding slide plate 301 is provided with an air extraction groove 403, the inside of the air extraction groove 403 is in communication with the inside of the communication air hole 402, and the inside of the sliding slide plate 301 is in communication with the outside of the sliding slide plate 301 through the air extraction groove 403.

[0049] The one-way valve air hole 401 and the air extraction groove 403 are air grooves for one-way air intake, the air intake end of the one-way valve air hole 401 is in communication with the outside of the telescopic sleeve 307, and the air intake end of the air extraction groove 403 is in communication with the outside of the sliding slide plate 301.

[0050] The one-way valve air hole 401 is used for one-way air exhaust when the telescopic sleeve 307 contracts, and when the telescopic sleeve 307 is stretched by the sliding slide plate 301, the one-way valve air hole 401 cannot intake air, and air can only enter through the air extraction groove 403, so that the air intake of the telescopic sleeve 307 is not limited;

[0051] When the sliding slide 301 is pulled back by the telescopic sleeve 307, the speed of the telescopic sleeve 307 in the retraction process is limited by the small-diameter one-way valve air hole 401, so that the speed of the sliding slide 301 in the resetting process is limited, the speed of the sliding slide 301 pulled back by the elastic rope 306 is prevented from being too fast, and the problem that the clamping block 302 and the cushion layer on the inner PVC bottom plate 303 are impacted and extruded again is prevented, the stable resetting of the sliding slide 301 is maintained, the impact degree caused by the quick pulling back of the sliding slide 301 by the elastic rope 306 and the cushion plate 309 is reduced, and the stable assembly work of the immunochromatography reagent is maintained.

[0052] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
