Description
Technical Field
[0001] The invention relates to the technical field of biomedical engineering industry, and in particular to an assembly tool used for large immunochromatographic reagent strip plates. Background Art
[0002] Immunochromatographic reagent strips are a rapid detection tool based on the principle of antigen-antibody reaction, which is widely used in clinical diagnosis, food safety, environmental monitoring and other fields; An assembly tool for immunochromatographic reagent strips described in the patent application with announcement number CN218567382U relates to the technical field of biomedical engineering industry, and includes a base and a film-sticking mold, wherein the upper surface of the base is provided with a limiting groove, the film-sticking mold is engaged in the limiting groove, buckles are symmetrically arranged at both ends of the limiting groove, and the inner side of the film-sticking mold is provided with at least one group of left-right symmetrical positioning grooves, and any group of the positioning grooves is arranged correspondingly to the buckles, and the film-sticking mold is provided with a film-sticking window; At present, when assembling a large plate of immunochromatographic reagent strips, the PVC bottom plate is fixed by a clamping piece and then placed on a turntable. The turntable is intermittently rotated and transported to the bottom of a robotic arm. When the turntable stops, the robotic arm grabs the immunochromatographic reagent strip cushion layer to be placed on the PVC bottom plate, and then continues to be rotated by the turntable to the next robotic arm, and the PVC top plate is covered to complete the assembly. When the turntable rotates, the cushion layer on the PVC bottom plate is easily swung outward by the centrifugal force of the rotation and squeezed with the clamping block that clamps it. The cushion layer is relatively soft, and once squeezed, it will warp and skew, resulting in misalignment of the internal cushion layer during subsequent top cover packaging, resulting in limited assembly accuracy. Summary of the invention

[0005] Preferably, one side of the sliding slide is fixedly connected to an elastic rope, one end of the elastic rope is fixedly connected to a fixing plate, and the bottom of the fixing plate is fixedly connected to the top of the disc.
[0006] Preferably, a telescopic sleeve is fixedly connected to one side of the fixed plate, and one end of the telescopic sleeve is fixedly connected to one side of the sliding slide.
[0007] Preferably, a pad is fixedly connected to the outer wall of the fixed block, and one side of the pad is in contact with one side of the sliding plate.
[0008] Preferably, a buffer mechanism is provided on the outer wall of the telescopic sleeve, and the buffer mechanism includes a one-way valve pore, the one-way valve pore is opened on the outer wall of the telescopic sleeve, and a connecting pore is opened inside the sliding slide, and the inside of the connecting pore is connected with the inside of the telescopic sleeve.
[0009] Preferably, the interior of the telescopic sleeve is communicated with the interior of the one-way valve pore, and the interior of the telescopic sleeve is communicated with the exterior of the telescopic sleeve through the one-way valve pore.
[0010] Preferably, an air extraction groove is provided on the top of the sliding slide, the interior of the air extraction groove is communicated with the interior of the communicating air hole, and the interior of the sliding slide is communicated with the exterior of the sliding slide through the air extraction groove.
[0011] Preferably, the one-way valve air hole and the air extraction groove are both one-way ventilation air grooves, the air inlet end of the one-way valve air hole is connected to the outside of the telescopic sleeve, and the air inlet end of the air extraction groove is connected to the outside of the sliding slide.
[0012] The present invention provides an assembly tool for a large plate of immunochromatographic reagent strips, which has the following beneficial effects: 1. The present invention provides a large plate clamping mechanism. When the disc rotates, the sliding slide and the clamping block loaded with the PVC bottom plate will slide toward the outer ring of the disc synchronously with the centrifugal force of rotation. The sliding slide slides on the sliding bar, so that the clamping block on the sliding slide slides outward together with the PVC bottom plate, and the squeezing force between the cushion layer on the PVC bottom plate and the clamping block when the cushion layer on the PVC bottom plate is subjected to the outward centrifugal force is relieved, thereby avoiding the problem of the cushion layer on the PVC bottom plate sliding and warping up onto the clamping block.
[0013] 2. The present invention sets a large plate clamping mechanism. When the sliding plate is pulled back and hits the pad and generates a certain collision vibration, the soft material of the pad can reduce the vibration generated by the sliding plate, and the remaining vibration of the sliding plate can be beneficial to the stable placement of various cushion layers placed on the PVC bottom plate at this time. The sliding plate drives the vibration of the PVC bottom plate, and each time the CNC robot arm places the various cushion layers on the sliding plate, it is vibrated and leveled to prevent the problem of cushion layer warping and skewing caused by deviation during placement.
[0014] 3. The present invention provides a buffer mechanism, so that when the air above the sliding slide is sucked into the telescopic sleeve by the upper air suction groove, an air flow path from top to bottom is generated, so that when the disc rotates, the reagent strip cushion layer that is easily lifted up on one side of the clamping block due to the centrifugal force can be pressed down as much as possible through the top-down flow of air, thereby reducing the occurrence of edge warping and skewing during the assembly process of the assembly line and maintaining the stability of the immunochromatography reagent strip assembly.
[0015] 4. The present invention sets a buffer mechanism. When the sliding plate is pulled back by the telescopic sleeve, the speed of the telescopic sleeve's retraction is limited by the small-caliber one-way valve pore, thereby limiting the speed of the sliding plate's resetting, preventing the sliding plate from being pulled back by the elastic rope too quickly, which would cause the clamping block and the cushion layer on the internal PVC bottom plate to be impacted and squeezed again, thereby keeping the sliding plate in a stable position, reducing the impact force caused by the elastic rope's rapid pull back and the cushion plate, and maintaining stable assembly of the immunochromatography reagent.

DETAILED DESCRIPTION
[0018] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: an assembly tool for a large plate of an immunochromatographic reagent strip, comprising a bottom plate 1 and an electric rotating table 5, a CNC mechanical arm 6 is fixedly connected to the top of the bottom plate 1, a disc 2 is arranged on the top of the electric rotating table 5, and a large plate clamping mechanism 3 is arranged on the top of the disc 2; The large plate clamping mechanism 3 comprises: The sliding slide 301 is a square plate structure. The top of the sliding slide 301 is fixedly connected with a clamping block 302. The bottom of the sliding slide 301 contacts with a sliding bar 304. The bottom of the sliding bar 304 is fixedly connected with the top of the disc 2. A PVC bottom plate 303 is placed on the top of the sliding slide 301. The outer wall of the PVC bottom plate 303 contacts one side of the clamping block 302. The sliding slide 301 is used to fix and clamp the PVC bottom plate 303. The fixed baffle 310 is a rectangular plate-shaped structure. The bottom of the fixed baffle 310 is fixedly connected to the top of the disc 2. The inner wall of the fixed baffle 310 is provided with a limiting groove 311. The limiting groove 311 is used to allow the sliding plate 301 and the clamping block 302 to be embedded therein to play a blocking role. The limiting groove 311 is adapted to its shape to prevent the problem of skewing caused by collision during blocking. The bottom of the sliding plate 301 is slidably connected to the surface of the disc 2 through the sliding bar 304. The fixed baffle 310 is used to limit the sliding plate 301. When in use, the PVC bottom plate 303 is clamped by the CNC mechanical arm 6 and then placed on the sliding plate 301 on the disc 2, and then the electric rotating table 5 controls the disc 2 to automatically rotate at a certain angle, and then stops after the rotation, and the CNC mechanical arms 6 on both sides continue to place the subsequent cushion layer on the PVC large plate on the sliding plate 301, so that as the disc 2 continues to rotate intermittently, the CNC mechanical arms 6 perform assembly line-style stacking and assembly work; Example 2: Please refer to Figure 1-9On the basis of the first embodiment, the present invention provides a technical solution: an elastic rope 306 is fixedly connected to one side of the sliding plate 301, one end of the elastic rope 306 is fixedly connected to a fixed plate 305, and the bottom of the fixed plate 305 is fixedly connected to the top of the disc 2.
[0019] A telescopic sleeve 307 is fixedly connected to one side of the fixed plate 305 , and one end of the telescopic sleeve 307 is fixedly connected to one side of the sliding plate 301 .
[0020] A pad 309 is fixedly connected to the outer wall of the fixed block 308, and one side of the pad 309 contacts one side of the sliding plate 301; When the disc 2 rotates, the stacked test strips placed on the PVC bottom plate 303 by the CNC robot arm 6 are easily squeezed and tilted by the clamping block 302 at the outer ring position of the disc 2 due to the outward centrifugal force when the disc 2 rotates, causing the cushion layer on the PVC bottom plate 303 to deform and tilt. When the disc 2 rotates, the sliding plate 301 and the clamping block 302 loaded with the PVC bottom plate 303 will slide toward the outer ring of the disc 2 synchronously with the outward centrifugal force caused by the rotation, and the sliding plate 301 slides on the sliding bar 304, so that the clamping block 302 on the sliding plate 301 and the PVC bottom plate 303 are pressed against each other. The C bottom plate 303 slides outwards together, relieving the squeezing force between the cushion layer on the PVC bottom plate 303 and the clamping block 302 when the cushion layer is subjected to the outward centrifugal force, thereby preventing the cushion layer on the PVC bottom plate 303 from sliding and warping up onto the clamping block 302. After the sliding slide plate 301 slides outwards, the sliding slide plate 301 pulls the elastic rope 306 to deform, and one end of the elastic rope 306 is fixed by the fixing plate 305, so that the elastic rope 306 will pull the sliding slide plate 301 back to its original position again through elastic force after deformation, and then the sliding slide plate 301 will be pulled back to the pad 309 by the elastic rope 306 and be pressed by the pad 309, thereby completing the return to its original position. The fixed baffle 310 and the limiting groove 311 formed on the inner wall of the fixed baffle 310 are used to fit the sliding plate 301 against the inner wall of the limiting groove 311 after the sliding plate 301 is thrown out, so as to limit the sliding plate 301, thereby preventing the problem of the sliding plate 301 being thrown out for a long distance due to the excessive rotation speed of the disc 2, and ensuring the uniformity of the time and speed of the sliding plate 301 returning to its original position, which is beneficial to the subsequent assembly work of the CNC robot arm 6; When the sliding plate 301 is pulled back and contacts the pad 309 and generates a certain collision vibration, the soft material of the pad 309 can reduce the vibration generated by the sliding plate 301, and the remaining vibration of the sliding plate 301 can be conducive to the stable placement of various cushion layers placed on the PVC bottom plate 303 at this time. The sliding plate 301 drives the vibration of the PVC bottom plate 303 to level various cushion layers placed on the sliding plate 301 by the CNC robot arm 6 each time, so as to prevent the cushion layer from warping and skewing due to deviation during placement. When the disc 2 rotates and drives the sliding plate 301, the clamping block 302 above and the PVC bottom plate 303 to slide outward, the sliding of the sliding plate 301 will pull the telescopic sleeve 307 to stretch. When the telescopic sleeve 307 stretches, the space inside the telescopic sleeve 307 expands to form a negative pressure. The telescopic sleeve 307 is connected to the air extraction groove 403 above the sliding plate 301 through the sliding plate 301. Therefore, when negative pressure is formed inside the telescopic sleeve 307, air will be sucked into the telescopic sleeve 307 through the air extraction groove 403, and the air extraction groove 403 is provided with a The air intake one-way valve allows the air extraction groove 403 to only take in air from the top and cannot exhaust air outward. As a result, when the air above the sliding plate 301 is sucked into the telescopic sleeve 307 by the air extraction groove 403 above, an air flow path from top to bottom is generated. When the disc 2 rotates, the reagent strip cushion layer that is easily lifted up on one side of the clamping block 302 due to the centrifugal force is pressed down as much as possible through the air flow from top to bottom, thereby reducing the occurrence of edge warping and skewing during the assembly process of the assembly line and maintaining the stability of the immunochromatographic reagent strip assembly. Example 3: Please refer to Figure 1-11 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a buffer mechanism 4 is provided on the outer wall of the telescopic sleeve 307, and the buffer mechanism 4 includes a one-way valve air hole 401, and the one-way valve air hole 401 is opened on the outer wall of the telescopic sleeve 307, and a connecting air hole 402 is opened inside the sliding slide 301, and the inside of the connecting air hole 402 is connected with the inside of the telescopic sleeve 307.
[0021] The interior of the telescopic sleeve 307 is communicated with the interior of the one-way valve air hole 401 , and the interior of the telescopic sleeve 307 is communicated with the exterior of the telescopic sleeve 307 through the one-way valve air hole 401 .
[0022] An air extraction groove 403 is provided on the top of the sliding plate 301 . The interior of the air extraction groove 403 is communicated with the interior of the communicating air hole 402 . The interior of the sliding plate 301 is communicated with the exterior of the sliding plate 301 through the air extraction groove 403 .
[0023] The one-way valve air hole 401 and the air extraction groove 403 are both one-way ventilated air grooves. The air inlet end of the one-way valve air hole 401 is connected to the outside of the telescopic sleeve 307, and the air inlet end of the air extraction groove 403 is connected to the outside of the sliding plate 301. The one-way valve air hole 401 is used for one-way discharge of air from the one-way valve air hole 401 when the telescopic sleeve 307 is contracted, and when the sliding plate 301 pulls the telescopic sleeve 307 to extend, the one-way valve air hole 401 cannot take in air, and air can only enter through the air extraction groove 403. The air extraction groove 403 has more and larger openings, so that the air intake of the telescopic sleeve 307 is not restricted; When the sliding plate 301 is pulled back by the telescopic sleeve 307, the retraction speed of the telescopic sleeve 307 is limited by the one-way valve air hole 401 with a smaller caliber, thereby limiting the speed at which the sliding plate 301 is reset, preventing the sliding plate 301 from being pulled back too quickly by the elastic rope 306, which would cause the clamping block 302 and the cushion layer on the internal PVC bottom plate 303 to be impacted and squeezed again, thereby keeping the sliding plate 301 stably returned to its original position, reducing the impact force caused by the elastic rope 306 quickly pulling it back and the cushion plate 309, and maintaining stable assembly of the immunochromatography reagent.
[0024] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
