Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1 to Figure 2 As shown, the utility model provides a technical solution: a reagent card loading and cutting device, used for reagent plate cutting and forming, comprising: a supply box 1, the supply box 1 is provided with a accommodating cavity for placing the reagent plate, the accommodating cavity is provided with a feeding port, a lifting platform 21 and a plurality of guide rods cooperating with the lifting platform 21 are provided in the supply box 1, the lifting platform 21 drives the supply box 1 to be fixedly connected with a driving motor 22, the output shaft of the driving motor 22 extends to the lower surface of the supply box 1, and cooperates with the lifting platform 21.

[0028] A plurality of guide plates 23 are fixedly connected in the supply box 1, and a plurality of guide plates 23 and the reagent plate lifting platform 21 are provided with guide holes through which the guide plates 23 pass. The guide plates 23 mainly form a storage space for placing the reagent plate with the lifting platform 21 (the supply box 1 is also provided with a swing door, which is also a part of the storage space, and opening the swing door can drive the reagent plate to be placed in the storage space). When the driving motor 22 drives the output shaft to rotate, the lifting platform 21 moves upward, thereby driving the reagent plate to move to the outside of the supply box 1. Since the guide plates 23 are fixed in the supply box 1, when the lifting platform 21 moves upward, the storage space is reduced. A sensor is also provided in the supply box 1 for sensing the distance of the lifting platform 21 moving upward.

[0029] The supply box 1 is fixedly connected with a conveying component and a cutting component, and the conveying component drives the reagent plate at the feeding port to be transported to the cutting component.

[0030] The conveying assembly includes: a fourth cylinder 17 fixedly arranged on the supply box 1, a telescopic rod of the fourth cylinder 17 fixedly connected to a conveying frame 18, a fifth cylinder 19 fixedly connected to the conveying frame 18, and a telescopic rod of the fifth cylinder 19 fixedly connected to two suction cups 20. The supply box 1 is provided with a slide rail (not shown in the figure) cooperating with the conveying frame 18, and the fourth cylinder 17 drives the conveying frame 18 to reciprocate linearly, thereby driving the reagent plate to be transported to the cutting assembly.

[0031] The telescopic rod of the fifth cylinder 19 drives the suction cup 20 downward, so that the suction cup 20 cooperates with the reagent plate to achieve adsorption of the reagent plate, and then the reagent plate is driven by the fourth cylinder 17 to be transported to the cutting assembly.

[0032] like Figure 1 , Figure 4 as well as Figure 5 As shown, the bracket 2 is fixedly connected to a rotating motor 13, the output shaft of the rotating motor 13 is fixedly connected to a driving roller 14, the bracket 2 is rotatably connected to a driven roller 15, and the driven roller 15 is arranged directly above the driving roller 14. The rotating motor 13 cooperates with the driving roller 14 and the driven roller 15, so as to efficiently drive the reagent plate to be transported to the bottom of the cutting assembly. The outer surfaces of the driving roller 14 and the driven roller are wrapped with an anti-slip layer (that is, the existing roller outer surface material), which is mainly used to increase friction and improve the conveying effect.

[0033] The bracket 2 is fixedly connected to a material guide frame 16, which has a feed port and a discharge port, and the feed port is wider than the discharge port.

[0034] In order for the reagent plate to better enter between the main roller and the driven roller 15, the guide rack 16 performs preliminary guidance. Since the width of the feed port is greater than the discharge port, it can be well guided. The position of the reagent plate is corrected in the process of entering the guide rack 16 to ensure that the reagent plate can be in good contact with the active roller 14 and the driven roller 15 at the discharge port.

[0035] like Figure 1 , Figure 3 , Figure 4 as well as Figure 5 As shown, the cutting assembly includes: a bracket 2 fixedly arranged on the supply box 1, the bracket 2 is fixedly connected to a driving assembly, the driving assembly is rotatably matched with a circular knife 3, the circular knife 3 is coaxially connected to a gear, and the bracket 2 is matched with a rack 4.

[0036] The supply box 1 is provided with a driving part 101, and the driving part 101 is fixedly connected to the first hydraulic cylinder 5. The telescopic rod of the first hydraulic cylinder 5 is matched with a frame 6. The frame 6 mainly adopts a base plate and a U-shaped frame. Through grooves matching the U-shaped frame are provided on both sides of the bracket 2. The through grooves mainly play a guiding role. The U-shaped frame passes through the through grooves and is fixedly connected to the base plate. The base plate is fixedly connected to the telescopic rod of the first hydraulic cylinder 5.

[0037] The top of the frame 6 (that is, the U-shaped frame) is fixedly connected to the rack 4, the bracket 2 is fixedly connected to a clamping platform 7, the frame 6 is provided with a clamping portion 601, the first hydraulic cylinder 5 drives the clamping portion 601 of the frame 6 to cooperate with the clamping platform 7 to clamp the reagent plate, and the rack 4 is in contact with the gear.

[0038] The driving assembly drives the gear and the rack 4 to cooperate, and drives the circular knife 3 to cut the reagent plate. The driving assembly includes: a sixth cylinder 24 fixedly arranged on the bracket 2, the telescopic rod of the sixth cylinder 24 is fixedly connected to a driving plate 25, the driving plate 25 is fixedly connected to a moving block 26, the moving block 26 is rotatably connected to the circular knife 3, the driving plate 25 is fixedly connected to a sliding block, and the bracket 2 is fixedly connected to a slide rail that cooperates with the sliding block.

[0039] When the first hydraulic cylinder 5 drives the clamping part 601 of the frame 6 to cooperate with the clamping platform 7, the rack 4 also engages with the rack 4. At this time, the sixth cylinder 24 drives the driving plate 25 and the moving block 26 to move, driving the gear of the circular knife 3 to cooperate with the rack 4. At this time, the gear rotates and drives the circular knife 3 to cut the reagent plate.

[0040] The supply box is fixedly connected to a conveying platform 102, the conveying platform 102 is fixedly connected to a second cylinder 8, and the telescopic rod of the second cylinder 8 is fixedly connected to a clamping assembly.

[0041] The clamping assembly includes: a third cylinder 9 fixedly arranged on the telescopic rod of the second cylinder 8, the telescopic rod of the third cylinder 9 is arranged perpendicular to the telescopic rod of the second cylinder 8, and the telescopic rod of the third cylinder 9 is fixedly connected to a lifting platform 10, the lifting platform 10 is provided with a processing groove 1001, the processing groove 1001 is provided with a plurality of through holes, and the plurality of through holes are connected to a vacuum pump through an air pipe.

[0042] The clamping assembly is mainly operated by the second cylinder 8 driving the third cylinder 9 to catch the cut reagent card, and the vacuum pump drives the through hole to ventilate, thereby driving the reagent card to be adsorbed and transported to the next station.

[0043] After cutting is completed, the tailings need to be recycled, and therefore, the bracket 2 is fixedly connected with a material guide plate 11 , and the conveying platform 102 is fixedly connected with a material receiving box 12 that cooperates with the material guide plate 11 .

[0044] The guide frame 16 is mainly provided with an inclined surface, which guides the tail material when it contacts the guide plate 11, and finally falls into the receiving box 12. Many moving distances of the present application are realized by sensors.

[0045] like Figures 1 to 5 As shown, when working, the reagent plate is placed in the accommodating space. When the driving motor 22 drives the output shaft to rotate, the lifting platform 21 moves upward, thereby driving the reagent plate to move to the outside of the supply box 1. Since the guide plate 23 is fixed in the supply box 1, the accommodating space is reduced when the lifting platform 21 moves upward.

[0046] The telescopic rod of the fifth cylinder 19 drives the suction cup 20 downward, so that the suction cup 20 cooperates with the reagent plate to achieve adsorption of the reagent plate.

[0047] In order for the reagent plate to better enter between the main roller and the driven roller 15, the guide rack 16 performs preliminary guidance. Since the width of the feed port is greater than the discharge port, it can be well guided. The position of the reagent plate is corrected in the process of entering the guide rack 16 to ensure that the reagent plate can be in good contact with the active roller 14 and the driven roller 15 at the discharge port.

[0048] By rotating the motor 13 in cooperation with the active roller 14 and the driven roller 15, the reagent plate is efficiently driven and transported to the bottom of the cutting assembly. When the active roller 14 and the driven roller 15 come into contact with the reagent plate, the suction cup 20 is released from the adsorption of the reagent plate, and the active roller 14 and the driven roller 15 drive the reagent plate to move toward the cutting assembly.

[0049] The rotating motor 13 drives the active roller 14 and the driven roller 15 to stop working. At this time, when the first hydraulic cylinder 5 drives the clamping part 601 of the frame 6 to cooperate with the clamping platform 7, the rack 4 also engages with the rack 4, and the clamping part 601 cooperates with the clamping platform 7 to clamp the reagent plate.

[0050] The sixth cylinder 24 drives the driving plate 25 and the moving block 26 to move, driving the gear and rack 4 of the circular knife 3 to cooperate. At this time, the gear rotates and drives the circular knife 3 to cut the reagent plate. When the sixth cylinder 24 drives the circular knife 3 to move in a straight line, the gear and rack 4 cooperate to drive the circular knife 3 to rotate, thereby improving the cutting efficiency.

[0051] When the reagent plate is cut, the vacuum pump drives the through holes on the lifting platform 10 to absorb the cut reagent card, and transports it to the next station through the second cylinder 8 and the third cylinder 9.

[0052] When only the tailings are left after the reagent plates are cut, the tailings are transported to the material receiving box 12 through the material guide plate 11, and the different reagent plates are processed into reagent cards in this reciprocating manner.

[0053] The embodiments disclosed in the present utility model are preferred embodiments, but are not limited thereto. Ordinary technicians in this field can easily understand the spirit of the present utility model based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present utility model, they are all within the protection scope of the present utility model.
