[0036] Please see Figures 1-9 As shown, the present invention relates to a medical sampling brush sorting device; comprising a working platform 1, wherein a plurality of spacer bars 7 are arranged at intervals on the working platform 1, and the spacer bars 7 adjacent to each other form a feeding gap 70 for placing a single brush, wherein a position detection sensor is provided at the end of each feeding gap 70; a conveyor belt assembly 6 is provided on the working platform 1, which is located below the plurality of spacer bars 7, wherein the conveyor belt assembly 6 drives the brush located in the feeding gap 70 to move along the length of the feeding gap 70 to the position detection sensor; a roller screening assembly 2 is provided on the working platform 1, which is located above the plurality of spacer bars 7, and the discharge port of the roller screening assembly 2 is aligned with the feeding gap 70; a suction device 5 is provided on the working platform 1, which is located on the side close to the position detection sensor; and a gripping assembly 4 is provided on the working platform 1, which grips the brush located at the end of the feeding gap 70 and conveys it to the suction device 5.

[0037] Please see Figures 7-8As shown, further, the drum screening assembly 2 and the plurality of spacing rods 7 are also provided with a vibrating feeding device 3, wherein the vibrating feeding device 3 comprises a vibrating bracket 31, a receiving hopper 32, and a vibrating motor 33, wherein the vibrating motor 33 and the receiving hopper 32 are arranged on the vibrating bracket 31, and the vibrating bracket 31 is arranged on the working platform 1, and the discharge port of the receiving hopper 32 is provided with a plurality of deviation correction rods 34, and the deviation correction rods 34 adjacent to each other form a deviation correction gap 341 parallel to the feeding gap 70.

[0038] Through the arrangement of the deviation correction gap 341, when the material passes through the vibrating feeding device 3, it tends to move in the longitudinal direction under the action of the vibration force, so that the material can more easily enter the feeding gap 70. The presence of the deviation correction rod 34 can limit the movement of the material in the transverse direction, ensuring that it enters the correct feeding gap 70. Such a design can improve work efficiency and reduce errors, ensuring the correct placement of the material.

[0039] Referring to Figures 7-8 As shown, further, the drum screening assembly 2 comprises a first driving motor 21, a drum screen 22, and a feeding hopper 23, wherein the side wall of the drum screen 22 is provided with a plurality of feeding holes 221, the feeding holes 221 are parallel to the deviation correction gap 341, the feeding hopper 23 is wrapped around the side wall of the drum screen 22, and the discharge port of the feeding hopper 23 is aligned with the inlet of the receiving hopper 32.

[0040] These feeding holes 221 are parallel to the deviation correction gap 341. The arrangement of the feeding holes 221 allows the material to fall into the feeding hopper 23 in a manner as parallel as possible to the deviation correction gap 341 during the rotation of the drum screen 22. The inlet of the feeding hopper 23 is wrapped around the side wall of the drum screen 22 to receive the material discharged from the feeding holes 221 of the drum screen 22. The discharge port of the feeding hopper 23 is aligned with the inlet of the receiving hopper 32 to ensure smooth transmission of the material.

[0041] Referring to Figure 4 As shown, further, the plurality of spacing rods 7 are divided into left spacing rods 7 and right spacing rods 7 from the middle, wherein the surface of the left spacing rods 7 is provided with a plurality of air blowing holes 72 facing the left side, the surface of the right spacing rods 7 is provided with a plurality of air blowing holes 72 facing the left side, and each spacing rod 7 is further provided with an air hole 71 in communication with the plurality of air blowing holes 72, wherein the air hole 71 is circumscribed by an air blowing device.

[0042] The surface of the left spacer rod 7 is provided with air blowing holes 72 facing to the left, and the surface of the right spacer rod 7 is provided with air blowing holes 72 facing to the left. The main function of these air blowing holes 72 is to deal with the possible brush stacking problem. When there are two brushes stacked in the material placing gap 70, the air flow generated by the air blowing holes 72 can blow the upper brush away from the stack and place it in another material placing gap 70. The surface of each spacer rod 7 is also provided with air vents 71 communicating with the air blowing holes 72. The function of the air vents 71 is to connect the air blowing holes 72 with external air blowing equipment to provide the required air flow for the air blowing holes 72. Through the arrangement of the air blowing holes 72 and the air vents 71, the air blowing equipment can provide air flow to the air blowing holes 72 of the left spacer rod 7 and the right spacer rod 7 through the air vents 71. When there is brush stacking, the air flow acts on the upper brush through the air blowing holes 72, blowing it away from the stack and placing it in the appropriate material placing gap 70. In this way, the confusion or error caused by brush stacking can be avoided.

[0043] Please refer to Figure 1 As shown, further, both sides of the work platform 1 are provided with a storage box 10, which is respectively towards the left spacer rod 7 and the right spacer rod 7, and the bottom of the storage box 10 is further provided with a storage drawer 101.

[0044] Specific analysis as follows:

[0045] Storage box 10: The storage box 10 provided on both sides of the work platform 1 is used to collect the brushes blown away by the air blowing holes 72. When the brushes are blown away from the material placing gap 70, they will fall into the corresponding storage box 10, which can prevent the brushes from falling to the ground or other places. The storage box 10 is located on both sides of the work platform 1, corresponding to the left spacer rod 7 and the right spacer rod 7 respectively.

[0046] Storage drawer 101: The storage drawer 101 provided at the bottom of the storage box 10 is to facilitate the removal of the collected brushes from the storage box 10. When a certain amount of brushes accumulate in the storage box 10, the operator can open the storage drawer 101 to easily remove these brushes for further processing or subsequent steps. The arrangement of the storage drawer 101 makes it convenient and fast to remove the brushes and can keep the working area clean.

[0047] Please refer to Figure 5As shown, further comprising a spacing feeding device, the spacing feeding device comprising a first roller brush motor 81, a second roller brush motor 82, a first cross rod 83, a second cross rod 84, wherein the first cross rod 83 and the second cross rod 84 are horizontally arranged above the spacing rod 7, and the first cross rod 83 is close to one side of the in-place detection sensor; wherein a plurality of push brushes 85 are sleeved on the first cross rod 83 and the second cross rod 84, and the push brushes 85 are aligned with the corresponding feeding gap 70, the first roller brush motor 81 drives the first cross rod 83 to rotate, the second roller brush motor 82 drives the second cross rod 84 to rotate, and the rotation speed of the first cross rod 83 is greater than that of the second cross rod 84.

[0048] The rotation speed of the first cross rod 83 is faster than that of the second cross rod 84, so as to push the front brushes faster and let the rear brushes approach the first cross rod 83 slowly. Such design can avoid excessive brushes accumulating at the position of the in-place sensor 9, and provide sufficient operation time for the grabbing assembly 4, similar to the effect of queuing.

[0049] In this way, the spacing feeding device can effectively control the feeding speed and position of the brushes to avoid accumulation and confusion. Pushing the front brushes faster and then pushing the rear brushes slowly can maintain the orderly arrangement of the brushes and provide better operation conditions for subsequent grabbing and processing. The difference in rotation speed of the first cross rod 83 and the second cross rod 84 needs to be reasonably set according to actual needs and design requirements to achieve the best brush feeding effect.

[0050] Please refer to Figure 6 As shown, further, the grabbing assembly 4 comprises a three-axis driving mechanism 41, a rotating mechanism 42, and a mechanical claw 43 arranged on the working platform 1, the three-axis driving mechanism 41 is drivingly connected with the rotating mechanism 42 and drives the rotating mechanism 42 to move along the space XYZ axis direction, and the rotating mechanism 42 is drivingly connected with the mechanical claw 43 and drives the mechanical claw 43 to rotate along the space C axis direction.

[0051] In this specific embodiment, the three-axis driving mechanism 41 is a three-axis driving mechanism 41 in the prior art, so the specific structure of the three-axis driving mechanism 41 will not be repeated here.

[0052] Please refer to Figure 6 As shown, in this specific embodiment, the in-place sensor 9 has the functions of detecting whether the brushes are in place and detecting whether the front end or the rear end of the brushes is in place.

[0053] In the embodiment, the adopted in-place sensor 9 is a matrix diffuse reflection fiber sensor in the prior art. In order to facilitate the understanding of the principle of detecting the in-place and front and rear ends, the working principle of the matrix diffuse reflection fiber sensor is specifically discussed below. The matrix diffuse reflection fiber sensor includes a plurality of optical signal receivers and a plurality of optical fiber heads for emitting light. Moreover, one optical signal receiver and one optical fiber head constitute a basic optical signal unit. Therefore, the in-place sensor 9 actually includes a plurality of optical signal units, and the plurality of optical signal units are arranged in a matrix.

[0054] The principle is discussed as follows. First, if the brush is not initially in place, the total sum of the light signal intensity received by the in-place sensor 9 is less than n (n is a preset value). At this time, the in-place sensor 9 determines that the brush has not moved to the in-place. The total sum of the light signal intensity received by the in-place sensor 9 is greater than or equal to n (n is a preset value). It is determined that the brush is in place.

[0055] The principle of determining the front and rear ends is similar, but the determined value is different. If the front end of the brush is close to the in-place sensor 9, the total sum of the light signal intensity reflected back to the in-place sensor 9 is m. If the rear end of the brush is close to the in-place sensor 9, the total sum of the light signal intensity reflected back to the in-place sensor 9 is f. Since the area of the front end of the brush is larger than that of the rear end, m will be greater than f. Therefore, a range value (m±100) and a range value (f±100) can be preset in the corresponding program.

[0056] Therefore, the complete identification is divided into two steps.

[0057] Step 1: detecting whether the brush is in place. When the total sum of the light signal intensity received by the in-place sensor 9 is less than n (n is a preset value), the in-place sensor 9 determines that the brush has not moved to the in-place. Therefore, the next step is not performed. When the total sum of the light signal intensity received by the in-place sensor 9 is greater than or equal to n (n is a preset value), it is determined that the brush is in place. The next step is performed.

[0058] Step 2: after the brush is determined to be in place, the total sum of the light signal intensity received by the in-place sensor 9 is compared with the range value (m±100) and the range value (f±100). If it falls within the range value (m±100), it is identified as the front end of the brush. If it falls within the range value (f±100), it is identified as the rear end of the brush.

[0059] The design of the rotating mechanism 42 driving the rotation of the mechanical claw 43 is to meet the requirement of sending the tail of the brush to the suction device 5, and to determine the front end and the rear end of the brush according to the signal of the in-place sensor 9. Through the detection of the in-place sensor 9, if the front end of the brush reaches the in-place sensor 9, the rotating mechanism 42 will be triggered to drive the mechanical claw 43 holding the brush to rotate to adjust the direction of the brush. In this way, it can be ensured that the tail of the brush is directed towards the suction device 5, so that it is sent to the suction device 5 for further processing in the preset direction. Such a design ensures the orientation and correctness of the brush during the feeding process. Through the cooperation of the rotating mechanism 42 and the mechanical claw 43, the control and adjustment of the direction of the brush can be realized to meet the requirement of sending the tail of the brush to the suction device 5.

[0060] Please refer to Figure 9 As shown, further, the suction device 5 includes a suction support 51 arranged on the working platform 1, and the surface of the suction support 51 is provided with a number of first suction holes 511 corresponding to the number of the material discharge gaps 70, and each first suction hole 511 is externally connected with a negative pressure device. Further, a control suction device 5 is arranged between the suction holes and the negative pressure device, which includes a control support 52, wherein the control support 52 is provided with a number of second suction holes 521 corresponding to the number of the first suction holes 511, wherein the first suction holes 511 are communicated with the second suction holes 521 through pipelines, and the second suction holes 521 are communicated with the negative pressure device through pipelines; wherein the top of the control support 52 is provided with a number of third communication holes corresponding to the second suction holes 521, and the control support 52 is provided with a number of push air cylinders 53 corresponding to the number of the third communication holes, wherein the movable end of each push air cylinder 53 is connected with a blocking block 54, and the push air cylinder 53 pushes the blocking block 54 into the third communication hole to block the corresponding second suction hole 521.

[0061] The top of the control support 52 is provided with a number of third communication holes corresponding to the number of the second suction holes 521. The control support 52 is also provided with a number of push air cylinders 53 corresponding to the number of the third communication holes. The movable end of each push air cylinder 53 is connected with a blocking block 54. When the push air cylinder 53 is activated, the blocking block 54 will enter the third communication hole and block the corresponding second suction hole 521, so that the suction force of the negative pressure device on each suction hole can be controlled.

[0062] The above embodiments only describe the preferred embodiments of the present application, and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements to the technical solutions of the present application made by ordinary engineering technical personnel in the art shall fall within the protection scope determined by the claims of the present application.
