[0002] Currently, the manufacturing process for test kits typically involves assembling reagent strips into reagent housings and then packaging them. During this process, the production of the reagent strips requires cutting a single strip into several individual strips.

[0020] The swing arm is provided with a blocking component to prevent the residual material of the reagent strip placed on the clamping mechanism from moving back as the clamping mechanism moves back.

[0024] The beneficial effects of this invention are as follows: The feeding device on the test kit production line is equipped with a stacking plate, a stacking rack, and a blocking mechanism for stacking reagent strips on the stacking plate for feeding. Then, a first driving device drives the adsorption and picking mechanism to move up and down, so that the vacuum suction cup of the adsorption and picking mechanism passes through the picking hole to adsorb the reagent strips placed at the bottom of the stacking plate and pick them out one by one from the picking hole, thereby realizing the production of multiple reagent strips. Furthermore, the upper surface of the free end of the blocking block of the blocking mechanism is inclined, so that when the reagent strips are adsorbed and picked out by the adsorption and picking mechanism, they will not encounter great resistance and are less likely to be damaged.

[0025] After the reagent strips are fed into the feeding device, they are conveyed and sliced ​​by the feeding device. The feeding device is equipped with a feeding platform with a feeding channel. The second support frame of the feeding device is equipped with a picking mechanism that can transport the reagent strips onto the feeding channel, and a feeding mechanism that can move back and forth and push the reagent strips along the feeding channel to the slicing device to slice the reagent strips into reagent slices.

At the same time, a tail-cutting mechanism is provided on the rear side of the support frame to cut the tail of the reagent strips placed on the feeding channel, so as to cut the rear end of the reagent strips flat, making it easier for the clamping mechanism to clamp the reagent strips for feeding.

[0026] When the reagent strip passes through the slicing device, the slicing device, via a second drive unit, drives the cutting assembly to cooperate with the fixed blades mounted on the slicing stage to cut the reagent strip located on the transport slicing slot into reagent slices. The cut reagent slices are then placed on the pad of the slicing stage.

Throughout the entire reagent slice production process, from feeding to slicing, the entire process is mechanically operated, achieving automated production and thus increasing production speed.

[0042] The technical solutions in the embodiments of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

[0043] Reference Figures 1 to 15 A reagent strip production device for a reagent kit production line includes a feeding device 1 for feeding reagent strips 4, a feeding device 2 located beside the feeding device 1 for taking out the reagent strips 4 from the feeding device 1 and placing them on it for forward transport, and a slicing device 3 located at the front end of the feeding device 2 for cutting the reagent strips 4 into reagent strips 5.

[0044] The feeding device 1 includes a first support frame 11, a stacking plate 12 on the upper part of the first support frame 11, a picking hole 121 on the stacking plate 12 for the reagent strip 4 to pass through, and a stacking rack 13 for limiting the area of ​​stacking reagent strip 4 on the side of the picking hole 121. At the same time, a blocking mechanism 14 is provided on the stacking plate 12 to prevent the reagent strip 4 from falling through the picking hole 121 under the action of gravity. There is also an adsorption picking mechanism 15 on the lower part of the first support frame 11 and below the stacking plate 12, which can move up and down and extend into the picking hole 121 to adsorb the reagent strip 4. A first driving device 16 is provided on the first support frame 11 to drive the adsorption picking mechanism 15 to move up and down.

[0045] The feeding device 2 includes a second support frame 21 and a feeding platform 22 disposed on the upper part of the second support frame 21. The feeding platform 22 is provided with a feeding channel 23 for placing the reagent strip 4. The second support frame 21 is provided with a picking mechanism 24 for transferring the reagent strip 4 from the feeding device 1 to the feeding channel 23. The support frame is also provided with a feeding mechanism 25 that can move back and forth and push the reagent strip 4 along the feeding channel 23 to pass through the slicing device 3 for slicing.

[0046] The slicing device 3 includes a third support frame 31, a slicing stage 32 disposed on the third support frame 31, a fixed blade 33 disposed at the front end of the slicing stage 32, a cutting assembly 34 disposed on the third support frame 31 and cooperating with the fixed blade 33 to cut the reagent strip 4 placed on the slicing stage 32 into reagent slices 5, and a second driving device 35 disposed on the third support frame 31 and driving the cutting assembly 34 to move. The slicing stage 32 is provided with a slicing groove 321 that is connected to the feeding channel 23 and can guide the reagent strip 4 to the front end of the slicing stage 32 for slicing under the action of external force.

[0047] During production, reagent strips 4 are stacked in the stacking rack 13. The first driving device 16 drives the adsorption and picking mechanism 15 to move upward and extend into the picking hole 121 to adsorb the reagent strips 4. Then, the first driving device 16 drives the adsorption and picking mechanism 15 to move downward, thereby removing the reagent strips 4 one by one from the stacking rack 13. After this, the picking mechanism 24 in the feeding device 2 extends into the feeding device 1 to pick up the reagent strips 4 and place them on the feeding channel 23. Then, the feeding mechanism 25 moves backward to the rear side of the reagent strips 4, clamps the rear end of the reagent strips 4 and moves them forward segment by segment, so that the reagent strips 4 can pass forward segment by segment through the slicing device 3. The cutting blade assembly 34 and the fixed blade 33 on the slicing device 3 cooperate to cut several identical reagent slices 5 from the reagent strips 4. The entire production process realizes mechanized and automated production, thereby improving production efficiency.

[0048] In this design, the blocking mechanism 14 includes several blocking blocks 141 disposed on the stacking plate 12 with one end extending into the dispensing hole 121. The free end of the blocking block 141 abuts against the bottom surface of the reagent strip 4, thus preventing the reagent strip 4 from falling through the dispensing hole 121 solely under gravity. Furthermore, the upper surface of the free end of the blocking block 141 is an inclined curved surface or a flat surface. This reduces the resistance encountered when the adsorption and dispensing mechanism 15 adsorbs and removes the reagent, and minimizes the deformation of the reagent strip 4 during dispensing, preventing damage to the reagent strip 4.

[0049] The stacking rack 13 includes several limiting rods 131 spaced apart on the stacking plate 12 and located next to the dispensing hole 121. The several limiting rods 131 form a rectangular area that matches the surface shape of the reagent strip 4, so that the reagent strip 4 can be stacked above the dispensing hole 121 without falling apart.

[0050] In this solution, the first driving device 16 includes a first cylinder 161 mounted on the first support frame 11; the adsorption and material handling mechanism 15 includes a first push plate 151 mounted on the output shaft of the first cylinder 161, a first fixing frame 152 mounted on the first push plate 151, and a vacuum suction cup assembly 153 mounted on the first fixing frame 152 that can adsorb onto the bottom surface of the reagent strip 4 and remove the reagent strip 4 from the material handling hole 121. The vacuum suction cup assembly 153 includes a suction cup base 1531 fixed on the first fixing frame 152, and a plurality of vacuum suction cups 1532 detachably mounted on the suction cup base 1531. The preferred number of vacuum suction cups 1532 is three evenly arranged vacuum suction cups 1532. By suctioning and degassing the vacuum suction cups 1532, the vacuum suction cups 1532 can remove the reagent strip 4 after adsorbing it. After removing the material, the vacuum suction cups 1532 will no longer adsorb the reagent strip 4, which makes it convenient for the material handling mechanism 24 on the feeding device 2 to transfer the reagent strip 4 placed on the surface of the vacuum suction cups 1532.

[0051] In this solution, in order to help staff know whether the material stacked on the stacking plate 12 has been taken out, a first sensor 122 is installed on the stacking plate 12. The probe of the first sensor 122 shines on the reagent strip 4 placed above the material taking hole 121. When the sensor probe can no longer shine on the reagent strip 4, an alarm will be issued to remind the staff and the device will stop working.

[0052] In this scheme, the material handling mechanism 24 includes a second fixed frame 241 mounted on the second support frame 21, several material handling trays 242 mounted on the second fixed frame 241 and movable left and right, and a third driving device 243 for driving the material handling trays 242 to move left and right. The upper surface of the material handling trays 242 is provided with a slot 2421 for transporting the reagent strips 4, and a hook plate is provided at the end of the slot 2421 where the material handling trays 242 extend, so as to facilitate the removal of the reagent strips 4 from the feeding device 1. When the material is picked up by the material picking mechanism 24, when the vacuum suction cup 1532 moves upward in the feeding device 1 to adsorb the reagent strip 4, the third driving device 243 will drive the material picking tray 242 to extend into the feeding device 1. When the vacuum suction cup 1532 adsorbs the reagent strip 4 upward and moves it back to its original position, the reagent strip 4 is just placed on the bottom surface of the slot 2421 of the material picking tray 242. In this way, the third driving device 243 drives the material picking tray 242 to move back to its original position, thereby transferring the reagent strip 4 in the feeding device 1 to the feeding channel 23. The third drive device 243 can be mounted on the second fixed frame 241 with a third cylinder 2431, and the output shaft of the third cylinder 2431 is connected to a first slide plate 244 that slides in cooperation with the second fixed frame 241. A first slide rail 2411 is provided on the second fixed frame 241, and the first slide plate 244 is mounted on the first slide rail 2411 and slides in cooperation with the second fixed frame 241. The material pick-up plate 242 is mounted on the first slide plate 244, so that the third cylinder 2431 can drive the material pick-up plate 242 to move left and right.

[0053] The feeding platform 22 includes several feeding plates 221 spaced apart on the upper part of the second support frame 21. Each feeding plate 221 is provided with a forward or backward feeding channel 23, and a pick-up plate 242 is disposed at the intervals of the feeding plates 221. The width of the feeding channel 23 is not less than the width of the slot 2421. After the pick-up plate 242 is driven back to its original position by the third driving device 243, the slot 2421 is connected to the feeding channel 23. Thus, after the reagent strip 4 located in the feeding device 1 is retrieved by the pick-up plate 242, the reagent strip 4 will be placed on the feeding channel 23.

[0054] In this scheme, the feeding mechanism 25 includes a clamping mechanism 251 disposed on the side of the second support frame 21 and capable of clamping the rear end of the reagent strip 4, and a feeding assembly 252 for driving the clamping mechanism 251 to move back and forth.

[0055] The feeding assembly 252 includes a mounting bracket 2521 mounted on the clamping mechanism 251. The bottom of the mounting bracket 2521 is provided with a slide module 2522 for driving the mounting bracket 2521 to move back and forth. A fifth driving device 2523, which can be a fifth cylinder 25231, is provided on the slide of the slide module 2522 to drive the mounting bracket 2521 to move up and down. The fifth driving device 2523 is used to raise the mounting bracket 2521 and thus the clamping mechanism 251 when it moves back, preventing the reagent strip 4 placed on the feeding channel 23 from being pushed out of the feeding channel 23 during the retraction process. A second sliding plate 2524 is connected to the output shaft of the fifth cylinder 25231 and slides in cooperation with the mounting bracket 2521. The mounting bracket 2521 is provided with a second slide rail 25211. The second sliding plate 2524 is mounted on the second slide rail 25211 and slides in cooperation with the mounting bracket 2521, so that the fifth cylinder 25231 can drive the mounting bracket 2521 to move up and down, thereby realizing the up and down movement of the clamping mechanism 251.

[0056] The clamping mechanism 251 includes a second push plate 2511 disposed on the upper part of the mounting frame 2521, a pressure plate 2512 disposed on the second push plate 2511 and movable up and down to press the reagent strip 4 onto the second push plate 2511, and a fourth driving device 2513 disposed on the second push plate 2511 and driving the pressure plate 2512 to move up and down. The bottom surface of the slot 2421 is not lower than the surface of the feeding channel 23, and the upper surface of the second push plate 2511 is not higher than the bottom surface of the slot 2421. The fourth driving device 2513 may be a fourth cylinder 25131. After the clamping mechanism 251 moves, the bottom surface of the reagent strip 4 will be located on the surface of the second push plate 2511, and then the pressure plate 2512 will move down and press it onto the second push plate 2511. Furthermore, guide grooves are provided on both the feeding channel 23 and the second push plate 2511 for picking up the reagent strip 4. When the clamping mechanism 251 is ready to clamp the reagent strip 4 and push it forward, the push plate is located in the guide groove and moves forward along the guide groove. At the same time, the upper surface of the second push plate 2511 is flush with the bottom surface of the guide groove, so that the bottom surface of the reagent strip 4 is placed on the upper surface of the second push plate 2511.

[0057] In this solution, because the reagent strip 4 was not processed before feeding, the rear end of the reagent strip 4 is not flush. This will make it difficult for the clamping mechanism 251 to clamp the reagent strip 4, and it may not be able to hold the reagent strip 4. Therefore, a clamping component 26 is provided on the feeding table 22 to press the reagent strip 4 against the bottom surface of the feeding channel 23. A tail-cutting mechanism 27 is provided on the rear side of the second support frame 21 to cut the tail of the reagent strip 4 placed on the feeding channel 23, so as to cut the rear end of the reagent strip 4 flat.

[0058] The clamping assembly 26 includes a clamping block 261 disposed on the feeding table 22 and capable of clamping the reagent strip 4 onto the feeding channel 23, and a sixth driving device 262 for driving the clamping block 261 to move up and down. The sixth driving device 262 may be a sixth cylinder 2621. The tail-cutting mechanism 27 includes a pressing knife assembly 28 capable of cutting the rear end of the reagent strip 4 flat, a connecting frame 271 disposed on the pressing knife assembly 28, and a base 272 disposed on the bottom of the connecting frame 271. A seventh cylinder 2621 is provided on the connecting frame 271 to drive the pressing knife assembly 28 to move up and down. The seventh driving device 273 can be a seventh cylinder 2731. The pressure knife assembly 28 includes a third sliding plate 281 mounted on the connecting frame 271 and a pressure knife 282 with its blade inclinedly mounted on the third sliding plate 281, which facilitates the cutting off of the rear end of the reagent strip 4. The third sliding plate 281 is mounted on the output shaft of the seventh cylinder 2731, and the connecting frame 271 is provided with a fourth slide rail 2711. The third sliding plate 281 is slidably mounted on the fourth slide rail 2711 of the connecting frame 271, so that the pressure knife assembly 28 and the connecting frame 271 slide in cooperation. A waste collection box 2712 is also installed at the bottom of the connecting frame 271 to collect the rear end of the reagent strip 4 cut off by the pressure knife assembly 28 for subsequent processing.

[0059] There is also an eighth drive device 274 on the base 272 that drives the connecting frame 271 to move back and forth. The eighth drive device 274 can be an eighth cylinder 2741, and the connecting frame 271 is connected to the output shaft of the eighth cylinder 2741. A third slide rail 2721 is provided on the base 272, and the connecting frame 271 is slidably mounted on the third slide rail 2721 of the base 272.

[0060] In this solution, a second sensor 222 is provided on the feeding platform 22 to detect the feeding status of the reagent strip 4 placed on the feeding channel 23. The probe of the second sensor 222 shines on the feeding channel 23 to reflect the feeding status of the reagent strip 4.

[0061] In this solution, a pad 36 is provided on the slicing stage 32 and at the front end of the fixed blade 33 for receiving the reagent slice 5 after slicing. The pad 36 is provided with a groove 361 to facilitate the removal of the reagent slice 5 from the pad 36.

[0062] In this scheme, the cutting assembly 34 can rotate up and down to cut the reagent strip 4 into slices by shearing with the fixed blade 33. The second driving device 35 is a second cylinder 351. A transmission assembly 37 is connected to the output shaft of the second cylinder 351, and the upper end of the transmission assembly 37 is connected to the free end of the cutting assembly 34 so that the second cylinder 351 can drive the cutting assembly 34 to rotate up and down. The cutting assembly 34 includes a swing arm 341 that is mounted on a third support frame 31 and can rotate up and down. A shearing blade 342 is provided on one side of the swing arm 341. After the swing arm 341 rotates up and down, the shearing blade 342 cuts with the fixed blade 33 to cut the reagent strip 4 into reagent slices 5.

[0063] In this scheme, the transmission assembly 37 includes a fixed seat 371 mounted on the third support frame 31 and a transmission plate 372 mounted on the fixed seat 371 and movable up and down. The lower part of the transmission plate 372 is connected to the output shaft of the second cylinder 351, and the upper part of the transmission plate 372 is movably connected to the free end of the swing arm 341, so that when the second cylinder 351 drives the transmission plate 372 to move up and down, it can drive the swing arm 341 to rotate up and down. Further, the upper end of the transmission plate 372 is provided with a stop post 373 that abuts against the lower end of the swing arm 341, and a follower 374 that presses the swing arm 341 against the stop post 373, so that the transmission plate 372 is movably connected to the free end of the swing arm 341.

[0064] In this design, a waste chute 311 is provided on the third support frame 31 at the bottom of the pad 36, and an air jet nozzle 362 is provided on the pad 36. Simultaneously, a waste trough communicating with the waste chute 311 is provided on the slicing groove 321. Because the front end face of the reagent strip 4 may not be flush, or when slicing the reagent strip 4 to the end, the remaining width of the reagent strip 4 may be insufficient to meet the width of the reagent slice 5, the front end face of the reagent strip 4 needs to be cut flush. The cut waste will fall onto the pad 36, and can then be blown onto the waste chute 311 for recycling via the air jet nozzle 362. Simultaneously, any remaining material that falls due to being blocked by the blocking component 38 will fall into the waste chute 311 for recycling.

The rotary drive device 393 can be a rotary cylinder 3931. The clamping mechanism 392 includes a pneumatic finger cylinder 394 that can clamp the reagent tablets 5 placed on the pad 36, and a tenth drive device 395 that drives the pneumatic finger cylinder 394 to extend or retract. The tenth drive device 395 can be a tenth cylinder 3951. After the pneumatic finger cylinder 394 clamps the reagent tablets 5, the rotary drive device 393 rotates the clamping mechanism 392 to the corresponding workstation to complete the next process.
