In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of the features, and are used to distinguish and describe features, without distinction of order or importance.

[0059] Please refer to Figures 1 to 8 The present invention provides a test paper cutting and distributing device, comprising a base 9 and a discharging mechanism 1, a feeding mechanism 2, a cutting mechanism 3, a conveying mechanism 4 and a visual detection mechanism 5 respectively arranged on the base 9;

[0060] The feeding mechanism 1 is used to grab the test paper raw material and place the test paper raw material on the feeding mechanism 2;

[0061] The feeding mechanism 2 is used to feed the test paper raw material to the cutting mechanism 3;

[0062] The cutting mechanism 3 includes a fixed frame 31, a sliding rod 32, an eccentric shaft 33, a rotating motor 35 and a cutting knife 36; the fixed frame 31 is fixed to the base 9 and is located at the output end of the feeding mechanism 2; the rotating motor 35 is arranged on one side of the fixed frame 31, and the movable end of the rotating motor 35 passes through the fixed frame 31 and is rotatably connected to the eccentric shaft 33; the sliding rod 32 is arranged on the other side of the fixed frame 31, and the eccentric shaft 33 is provided with a driving rod 34, one end of the driving rod 34 is provided with a shaft sleeve, the shaft sleeve is sleeved on the outside of the eccentric shaft 33 and is rotatably connected to the eccentric shaft 33, and the other end is hinged to the lower end of the sliding rod 32; the upper end of the sliding rod 32 is slidably connected to the fixed frame 31; the cutting knife 36 is connected to the top end of the sliding rod 32; the upper end of the fixed frame 31 is provided with a cutting groove 37 adapted to the cutting knife 36;

[0063] The conveying mechanism 4 is arranged at the front side of the cutting mechanism 3 and is used to transport the test paper;

[0064] The visual inspection mechanism 5 is used to remove test papers with size errors.

[0065] The cutting and distributing equipment realizes the cutting of the test paper through the discharging mechanism 1, the feeding mechanism 2, the cutting mechanism 3 and the conveying mechanism 4. During the cutting process, the discharging mechanism 1 will grab the test paper raw material and place the test paper raw material on the feeding mechanism 2; the feeding mechanism 2 will then deliver the test paper raw material to the cutting mechanism 3, and the cutting mechanism 3 will be responsible for cutting the test paper. After the cutting is completed, the cutting and distributing equipment will then detect the cut test paper by setting up a visual inspection mechanism 5, and remove the test paper with size error. The staff can adjust the cutting and distributing equipment in time according to the amount of test paper with size error generated, so as to reduce the scrap rate of the test paper during the cutting process.

[0066] by Figure 5 For example, when the cutting machine is working, the rotating motor 35 will rotate at a uniform speed, driving the eccentric shaft 33 to rotate; the axis of the eccentric shaft 33 and the movable end of the rotating motor 35 do not coincide, and the eccentric shaft 33 will rotate eccentrically; because the sleeve is arranged on the outside of the eccentric shaft 33, the driving rod 34 is hinged to the lower end of the sliding rod 32, and when the eccentric shaft 33 rotates, the sliding rod 32 converts the rotation of the eccentric shaft 33 into a regular swing; at the same time, the driving rod 34 rotates with its hinge point with the lower end of the sliding rod 32 as the center, offsetting the left and right directions of the swing of the sliding rod 32 caused by the driving rod 34 when it rotates eccentrically, so that the driving rod 34 drives the sliding rod 32 to move up and down, thereby achieving the purpose of the eccentric shaft 33 driving the sliding rod 32 to move up and down. Through the cooperation of the eccentric shaft 33, the driving rod 34 and the sliding rod 32, the rotation of the output end of the rotating motor 35 is converted into a reciprocating up and down movement, and the distance that the upper end of the sliding rod 32 extends from the fixed frame 31 is periodically changed, so that the cutting knife 36 is driven by the sliding rod 32 to periodically contact the cutting groove 37, thereby achieving the purpose of cutting the test paper.

[0067] The cutting and dividing equipment controls the cutting knife 36 through the eccentric shaft 33 to achieve the purpose of cutting the test paper. Compared with the cutting method using a cylinder to control the cutting knife, the cutting method of controlling the cutting knife 36 through the eccentric shaft 33 has a fixed cutting cycle and is easier to control the production rhythm. Moreover, the eccentric shaft is a circular motion, which is more stable and less prone to impact than the cylinder structure, and the mechanical structure has a longer life.

[0068] The feeding mechanism 2 feeds the front end of the test paper raw material into the cutting mechanism 3. When the test paper raw material enters the cutting mechanism 3, the cutting knife 36 will fall into the cutting groove 37, and then the sliding rod 32 drives the cutting knife 36 to rise, cutting the front end of the test paper raw material into a strip of test paper; the test paper will remain in the cutting groove 37, and the conveying mechanism 4 will move it to the visual inspection mechanism 5; then, the feeding mechanism 2 feeds the new front end of the test paper raw material after cutting into the cutting mechanism 3, and repeats the cutting steps. Since the up and down movement cycle of the cutting knife 36 is fixed, the staff can adjust the actual width of the test paper by changing the length of the test paper raw material entering the cutting mechanism 3.

[0069] Furthermore, the visual inspection mechanism 5 includes an extension frame 51, a visual inspection device 52 and a material return cylinder 53;

[0070] The extension frame 51 is provided with a screening slot 511 and a pressure strip 512; the screening slot 511 is arranged along the test paper conveying direction, and the screening slot 511 is connected to the downstream end of the cutting slot 37, and the bottom of the screening slot 511 is connected to the outside;

[0071] The upstream end of the screening slot 511 is further provided with a first side plate 513 and a second side plate 514, wherein the first side plate 513 is embedded in the front side of the screening slot 511, and the second side plate 514 is embedded in the rear side of the screening slot 511, and the first side plate 513 and the second side plate 514 are both inclined downward toward one side of the screening slot 511; the upper surfaces of the first side plate 513 and the second side plate 514 are respectively provided with reference lines;

[0072] The fixed end of the pressure strip 512 is connected to the upstream end of the extension frame 51, and the free end of the pressure strip 512 extends toward the screening slot 511;

[0073] The visual inspection device 52 is electrically connected to the material-returning cylinder 53 . The visual inspection device 52 is disposed above the first side plate 513 and the second side plate 514 . The material-returning cylinder 53 is disposed at the rear side of the second side plate 514 .

[0074] The conveying mechanism 4 moves the test paper from the cutting groove 37 to the screening groove 511. The bottom of the screening groove 511 is connected to the outside. If the width of the test paper is too narrow, it will fall out directly from the bottom of the screening groove 511. The first side plate 513 and the second side plate 514 act as reference objects. The visual inspection device 52 compares the two sides of the test paper with the reference lines on the first side plate 513 and the second side plate 514 to determine the width of the test paper. If the width of the test paper is too large, the return cylinder 53 is activated by an electrical signal to extend the active end of the return cylinder 53 to push out the test paper. If the size of the test paper meets the requirements, the conveying mechanism 4 moves the test paper out of the visual inspection mechanism 5. The pressure strip 512 acts to press the test paper to prevent the test paper from tilting during transportation.

[0075] Furthermore, the conveying mechanism 4 includes a cutting slot conveying assembly and a screening slot conveying assembly;

[0076] The cutting groove transport assembly includes a driver 41, a connector 42, a guide rod 43, a fixed frame rail 44 and a first push block 45; the fixed frame rail 44 is arranged on the upper surface of the fixed frame 31; the movable end of the driver 41 is connected to the left side of the connector 42; the guide rod 43 is located above the driver 41, one end of the guide rod 43 is connected to the left side of the connector 42, and the other end is connected to the first push block 45; the bottom surface of the first push block 45 is slidably connected to the fixed frame rail 44, and the rear side of the first push block 45 is clamped in the cutting groove 37;

[0077] The screening trough transport assembly includes an extension frame rail 46, a second push block 47, a return spring 48, a rotating plate 49, a baffle 410 and a U-shaped plate 411; the extension frame rail 46 is arranged below the extension frame 51; the second push block 47 is connected to the right side of the connecting member 42, and the rear side of the second push block 47 is slidably connected to the extension frame rail 46; a groove is provided at the upper end of the second push block 47, and the rotating plate 49 is hinged to the left side of the groove; one end of the return spring 48 is connected to the movable end of the rotating plate 49, and the other end is connected to the bottom of the groove; one side wall of the U-shaped plate 411 is connected to the rotating plate 49, and the other side wall extends into the screening trough 511 from below; the baffle 410 is arranged on the lower surface of the upstream end of the extension frame 51, and is arranged corresponding to the position of the rotating plate 49, and the rotating plate 49 gradually tilts downward toward the baffle side.

[0078] The conveying mechanism 4 includes two parts: a cutting slot transport component and a screening slot transport component. The cutting slot transport component moves the test paper from the cutting slot 37 to the screening slot 511, while the screening slot transport component moves the test paper that has passed the size inspection out of the screening slot 511. The cutting slot transport component and the screening slot transport component are both powered by the driver 41. Therefore, the process of moving the test paper from the cutting slot 37 to the screening slot 511 and the process of moving the test paper out of the screening slot 511 are carried out simultaneously. The driver 41 can refer to the existing single-axis robot. The driver 41 is driven by a ball screw and moves with the fixed frame track 44 and the extension frame track 46 as guides.

[0079] by Figure 6For example, when the test paper is cut, the movable end of the driver 41 pushes the connecting member 42 to move to the right. The connecting member 42 drives the guide rod 43 during the movement, so that the guide rod 43 drives the first push block 45 to move to the right on the fixed frame rail 44. Since the rear side of the first push block 45 is engaged in the cutting groove 37, the test paper will be pushed during the movement to the right, so that the test paper enters the screening groove 511. At the same time, the connecting member 42 also drives the second push block 47 during the movement, so that the second push block 47 moves to the right on the extension frame rail 46. The second push block 47 drives the rotating plate 49 and the U-shaped plate 411 to move. Since the other side wall of the U-shaped plate 411 extends from the bottom of the screening groove 511, the other side wall of the U-shaped plate 411 pushes the test paper out of the screening groove 511 and works together with the pressure strip 512 to clamp the test paper.

[0080] Please refer to Figure 8 Before the next cutting, the movable end of the driver 41 pushes the connecting member 42 to move to the left, and the first push block 45 and the second push block 47 are reset through the connecting member 42; during the reset process of the second push block 47, the baffle 410 abuts against the rotating plate 49, and applies pressure to the reset spring 48, so that the rotating plate 49 rotates counterclockwise with the hinge as the center, and the rotating plate 49 drives the U-shaped plate 411 to move downward, so that the other side wall of the U-shaped plate 411 retracts to the bottom of the screening slot 511. When the connecting member 42 moves to the right, the pressure on the reset spring 48 disappears, driving the rotating plate 49 to reset, so that the rotating plate 49 rotates clockwise with the hinge as the center, and drives the U-shaped plate 411 to extend upward into the bottom of the screening slot 511, thereby achieving the purpose of clamping the test paper. The reset spring 48 plays the role of pressing the rotating plate 49 tightly, and the rotating plate 49 has a moderate force when extending, so as to avoid the problem of damaging the test paper when the rotating plate 49 is extended.

[0081] Specifically, the test paper cutting and distributing device further comprises a material receiving mechanism 6, and the material receiving mechanism 6 comprises a movable fixture mechanism and a flattening device;

[0082] The movable fixture mechanism includes a movable cylinder 61 and a test paper placement rack 62; one end of the movable cylinder 61 is arranged at the downstream end of the extension rack 51, and the test paper placement rack 62 is connected to the movable end of the movable cylinder 61; the test paper placement rack 62 is provided with a plurality of test paper slots 621, and the test paper slots 621 are provided with an opening toward the side of the extension rack 51;

[0083] The flattening device includes a transverse cylinder 63 and a longitudinal cylinder 64. The transverse cylinder 63 is arranged at the other end of the movable cylinder 61, and the longitudinal cylinder 64 is arranged on one side of the movable cylinder 61. The heights of the movable ends of the transverse cylinder 63 and the longitudinal cylinder 64 are adapted to the test paper slot 621.

[0084] The receiving mechanism 6 is used to collect and organize the test papers pushed out from the screening slot 511. The movable cylinder 61 can refer to the existing mechanical rodless cylinder. The movable end of the movable cylinder 61 is a piston. The piston is directly connected to the test paper placement rack 62, so that the test paper placement rack 62 follows the piston to achieve reciprocating motion. The horizontal cylinder 63 and the vertical cylinder 64 are used to organize the position of the test paper to avoid the position of the test paper being offset when entering the test paper slot 621, which makes the test paper become messy.

[0085] During the movement, the moving cylinder 61 drives the test paper placement rack 62 to move, so that the opening of the test paper slot 621 is aligned with the outlet of the screening slot 511, and the test paper directly enters the test paper slot 621 after being pushed out of the screening slot 511; then, the moving cylinder 61 moves again, so that the opening of the next test paper slot 621 is aligned with the outlet of the screening slot 511, so that another test paper enters the test paper slot 621; this reciprocating process continues until all the test paper slots 621 are filled with test papers, and the movable end of the moving cylinder 61 is moved. The test paper rack 62 is driven to move toward the other end of the movable cylinder 61; then, the movable end of the longitudinal cylinder 64 extends out, and the test paper is pushed into the test paper slot 621 from the opening direction of the test paper slot 621; at the same time, the movable end of the transverse cylinder 63 also extends out, and the test paper is pushed into the test paper slot 621 from the notch direction of the test paper slot 621; then the movable end of the transverse cylinder 63 and the movable end of the longitudinal cylinder 64 are reset, and at this time, the test paper is removed from the test paper slot 621 to obtain a test paper that meets the required size. Through the cooperation of the movable cylinder 61, the test paper rack 62, the transverse cylinder 63 and the longitudinal cylinder 64, the test papers can be stacked neatly for subsequent processing.

[0086] In a specific embodiment, the material discharging mechanism 1 includes a material discharging support 11, a rodless cylinder 12 and a material discharging manipulator 13;

[0087] The lower end of the material discharging bracket 11 is connected to the base 9, the upper end of the material discharging bracket 11 is connected to the rodless cylinder 12, and the material discharging manipulator 13 is connected to the movable end of the rodless cylinder 12; the bottom surface of the material discharging manipulator 13 is provided with a suction cup.

[0088] The discharge mechanism 1 controls the displacement of the discharge manipulator 13 through the rodless cylinder 12. The rodless cylinder 12 can refer to the existing mechanical rodless cylinder 12. The movable end of the rodless cylinder 12 is a piston. The discharge mechanism 1 directly connects the discharge manipulator 13 with the piston, so that the discharge manipulator 13 follows the piston to achieve reciprocating motion. The discharge manipulator 13 is connected to the external air pipe, and the external air pipe draws air through the suction cup to form a negative pressure, so that the suction cup can absorb the test paper raw material. The discharge bracket 11 plays the role of supporting the rodless cylinder 12 and the discharge manipulator 13, so that the position of the rodless cylinder 12 and the discharge manipulator 13 is higher than the feeding mechanism 2.

[0089] During the working process, the unloading robot 13 absorbs the test paper raw material through the suction cup; then, the movable end of the rodless cylinder 12 moves the unloading robot 13 to the top of the feeding mechanism 2, the suction cup stops suction, the unloading robot 13 no longer absorbs the test paper raw material, and the test paper raw material falls into the feeding mechanism 2.

[0090] Specifically, the discharge mechanism 1 also includes a transfer block 14 and a lifting cylinder 15; the transfer block 14 is in an "L" shape, one end of the transfer block 14 is connected to the movable block of the rodless cylinder 12, and the other end is connected to the lifting cylinder 15; the movable end of the lifting cylinder 15 faces downward and is connected to the discharge robot 13.

[0091] The unloading mechanism 1 also shortens the distance between the unloading manipulator 13 and the feeding mechanism 2 through the lifting cylinder 15, so as to avoid the problem of large position deviation when the test paper raw material falls into the feeding mechanism 2. In the process of placing the test paper raw material, the movable end of the lifting cylinder 15 extends downward, driving the unloading manipulator 13 to move downward, thereby shortening the distance between the unloading manipulator 13 and the feeding mechanism 2; when the test paper raw material falls into the feeding mechanism 2, the movable end of the lifting cylinder 15 retracts upward, driving the unloading manipulator 13 to reset.

[0092] Specifically, it also includes a lifting material storage device 7, which is located below the material discharge mechanism 1 and includes a lifting cylinder 71, a placement plate 72 and a plurality of limit rods 73;

[0093] The lifting cylinder 71 is arranged below the base 9 , and the movable end of the lifting cylinder 71 passes through the base 9 and is connected to the placement plate 72 ; a plurality of limiting rods 73 are arranged around the placement plate 72 .

[0094] The lifting storage device 7 is used to place the test paper raw materials and provide the test paper raw materials for the discharge mechanism 1. The test paper raw materials are placed on the placement plate 72. When the discharge mechanism 1 needs to grab the test paper raw materials, the movable end of the lifting cylinder 71 extends upward, driving the placement plate 72 to move upward, so that the test paper raw materials contact the suction cup of the discharge robot 13; after the discharge robot 13 grabs the test paper raw materials, the movable end of the lifting cylinder 71 retracts downward, driving the placement plate 72 to reset. Several limit rods 73 are used to limit the position of the test paper raw materials to avoid the test paper raw materials being affected by external forces during the upward movement of the placement plate 72, resulting in the test paper raw materials being scattered and the discharge mechanism 1 being unable to grab the test paper raw materials.

[0095] Furthermore, the feeding mechanism 2 includes a receiving plate 21, a receiving bracket 22, a paper pushing slider 23 and a paper pushing cylinder 24;

[0096] The lower end of the receiving bracket 22 is connected to the base 9, the upper end of the receiving bracket 22 is connected to the receiving plate 21, and the front side of the receiving plate 21 is connected to the upstream end of the cutting mechanism 3; the paper pushing cylinder 24 is arranged below the receiving plate 21, and a clearance position 211 is provided in the middle of the receiving plate 21, and slide rails 212 are respectively provided on the left and right sides of the clearance position 211; one end of the paper pushing slider 23 is connected to the output end of the paper pushing cylinder 24, and the other end passes through the clearance position 211 and is slidably connected to the slide rail 212.

[0097] The unloading mechanism 1 places the test paper raw material on the receiving plate 21, and the feeding mechanism 2 drives the paper pushing slider 23 through the paper pushing cylinder 24, and the avoidance position 211 provides a sliding space for the slide rail 212 to slide, so that the paper pushing slider 23 slides on the slide rail 212, thereby pushing the test paper raw material into the cutting mechanism 3 through the paper pushing slider 23. The upstream end of the cutting mechanism 3 is the uncut end of the cutting mechanism 3. The receiving bracket 22 plays the role of supporting the receiving plate 21, so that the height of the receiving plate 21 is adapted to the upstream end of the cutting mechanism 3.

[0098] Furthermore, the paper pushing assembly further includes a left positioning plate 25 and a right positioning plate 26;

[0099] The left positioning plate 25 is arranged on the left side of the paper pushing slider 23, and a left fixed wheel 251 is arranged on the surface of the left positioning plate 25; the right positioning plate 26 is arranged on the right side of the paper pushing slider 23, and a right fixed wheel 261 is arranged on the surface of the right positioning plate 26;

[0100] The left fixed wheel 251 and the right fixed wheel 261 are arranged opposite to each other, and the axes of the left fixed wheel 251 and the right fixed wheel 261 are parallel to the sliding direction of the slide rail 212 .

[0101] The left positioning plate 25 and the right positioning plate 26 play a positioning role, respectively limiting the test paper raw material from the left and right sides, to prevent the test paper raw material from being displaced in the left and right directions when being pushed by the paper pushing slider 23, resulting in errors during cutting. The left fixed wheel 251 and the right fixed wheel 261 play a role in pressing the test paper raw material, to prevent the test paper raw material from protruding before entering the cutting mechanism 3, resulting in dimensional errors during the cutting process.

[0102] Preferably, the test paper cutting and dispensing equipment further comprises a tailing recovery device 8, wherein the tailing recovery device 8 comprises a support frame 81, a steering motor 82, a tailing recovery grabber 83 and a recovery box 84;

[0103] The support frame 81 and the recovery box 84 are arranged on the right side of the feeding mechanism 2; the support frame 81 is connected to the base 9, the fixed end of the steering motor 82 is connected to the support frame 81, and the movable end of the steering motor 82 is connected to the tail material recovery grabbing member 83, and the tail material recovery grabbing member 83 is used to grab the test paper raw material;

[0104] The distance between the recovery box 84 and the support frame 81 is the same as the distance between the tail material recovery grabbing member 83 and the feeding mechanism 2 .

[0105] The tail material recovery device 8 is used to recover the test paper raw materials remaining after cutting. The tail material recovery grabber 83 is provided with an adsorption disk. The tail material recovery grabber 83 is connected to an external air pipe. The external air pipe sucks air through the adsorption disk to generate negative pressure to achieve the purpose of grabbing the remaining test paper raw materials. The support frame 81 plays the role of supporting the steering motor 82 and the tail material recovery grabber 83, so that the height of the tail material recovery grabber 83 is adapted to the height of the receiving plate 21. In a specific embodiment, the movable end of the steering motor 82 is a rotating arm, and the rotating end of the rotating arm is connected to the tail material recovery grabber 83.

[0106] When the remaining test paper raw material needs to be recovered, the active end of the steering motor 82 rotates, and drives the tail material recovery grabbing member 83 to rotate, so that the tail material recovery grabbing member 83 is located above the receiving plate 21 in the feeding mechanism 2; then, the tail material recovery grabbing member 83 grabs the remaining test paper raw material located on the receiving plate 21; after grabbing, the active end of the steering motor 82 rotates in the opposite direction, drives the tail material recovery grabbing member 83 to reset, and rotates the tail material recovery grabbing member 83 to the top of the recovery box 84;

[0107] Finally, the tailings recovery grabbing member 83 releases the remaining test paper raw material, causing the remaining test paper raw material to fall into the recovery box 84, thereby realizing the collection of the tailings.
