[0037] For details, please refer to Figure 1 , Figure 2 , Figure 3 This application provides a waiting-type cyclic sample loading device, which includes a horizontal transfer base 1, a magnetic sample holder 2, and a flipping mixing device 3.
[0038] Please see Figure 2 , Figure 3 , Figure 4 The horizontal transfer base 1 includes a translation drive mechanism 11, a magnetic moving tray 12, and a horizontal base plate 13. The magnetic moving tray 12 is connected to the translation drive mechanism 11. The translation drive mechanism 11 drives the magnetic moving tray 12 to move in a first direction or a second direction in the horizontal plane. The first direction and the second direction are perpendicular. The horizontal base plate 13 is arranged parallel above the magnetic moving tray 12. The horizontal base plate 13 is provided with a sample loading waiting area 131, a sample mixing area 132, and a sample unloading area 133 corresponding to the moving area of the magnetic moving tray 12.
[0039] Please see Figure 5 , Figure 6The upper surface of the magnetic sample holder 2 is provided with multiple blood collection tube slots 21. The magnetic sample holder 2 is located on the horizontal base plate 13. The magnetic sample holder 2 is attracted and dragged by the magnetic moving tray 12 and transferred between the sample loading waiting area 131, the sample mixing area 132 and the sample unloading area 133.
[0040] Please see Figure 7 , Figure 8 The flipping mixing device 3 is located in the sample mixing area 132. The flipping mixing device 3 includes a flipping drive mechanism 31 and a flipping bracket 32. The flipping bracket 32 is engaged with the magnetic sample holder 2 from the sample loading waiting area 131. The flipping drive mechanism 31 is connected to the flipping bracket 32 and controls the flipping bracket 32 to flip. After flipping, the flipping bracket 32 is attracted and dragged by the magnetic moving tray 12 to separate from the magnetic sample holder 2 and move to the sample removal area 133.
[0041] The waiting-type cyclic sample loading device integrates the equipment for the blood collection tube sample loading process, reduces the space occupied by the equipment, and automates the waiting-type cyclic sample loading of multiple batches of blood collection tube samples, reducing manual operation and improving processing efficiency.
[0042] Furthermore, the waiting-type cyclic sample loading device has a front end and a rear end, and also includes a scanning module located at the front end. The scanning module scans the QR code on the blood collection tube fixed on the magnetic sample holder 2. The scanning module can scan and acquire multiple batches of blood collection tube samples to control the waiting-type cyclic sample loading.
[0043] In use, the blood collection tube is inserted into the blood collection tube slot 21 of the magnetic sample holder 2. The side of the blood collection tube slot 21 is provided with a spring piece 23 to press the blood collection tube. The magnetic sample holder 2 is placed in the sample loading waiting area 131. The QR code on the blood collection tube fixed on the magnetic sample holder 2 is scanned by the scanning module to obtain the information of the corresponding blood collection tube and the information of the sample inside. Then, the horizontal transfer base 1 drives the magnetic sample holder 2 to be transferred to the sample mixing area 132. The magnetic sample holder 2 is moved and engaged on the flipping support 32 of the flipping mixing device 3 to flip the magnetic sample holder 2 to shake the blood collection tube sample fixed on the magnetic sample holder 2. The sample is then removed by inserting a steel needle into the blood collection tube through an external robotic arm. Then, the magnetic sample holder 2 is attracted and dragged away from the flipping support 32 of the flipping mixing device 3 by the magnetic moving tray 12. The blood collection tube with the sample removed is transferred from the sample mixing area 132 to the sample removal area 133.
[0044] Please see Figure 3 , Figure 9The sample loading waiting area 131, the sample mixing area 132, and the sample unloading area 133 are arranged in a U-shape. The sample loading waiting area 131 and the sample unloading area 133 are arranged side by side at the front end, and the sample mixing area 132 is located at the rear end.
[0045] Please see Figure 3 , Figure 9 The horizontal transfer base 1 further includes a limiting partition 14 and a stop plate 15. The limiting partition 14 is disposed on both sides of the sample loading waiting area 131 and the sample unloading area 133, forming a translation channel between the two limiting partitions 14. The width of the translation channel is equal to the length of the magnetic sample holder 2. The stop plate 15 is disposed between the sample loading waiting area 131 and the sample mixing area 132. A channel is provided between the stop plate 15 and the limiting partition 14. The width of the channel is greater than the width of the magnetic sample holder 2. The flipping drive mechanism 31 is disposed adjacent to the stop plate 15, and the flipping bracket 32 is disposed corresponding to the sample unloading area 133.
[0046] The translational channel formed between the limiting partitions 14 enables the magnetic sample holder 2 to maintain a non-tilted sliding motion. The channel can pass through the magnetic sample holder 2 laterally, facilitating the transfer of the magnetic sample holder 2 to the flipping bracket 32.
[0047] Please see Figure 4The translation drive mechanism 11 includes a base plate 111, a first motor 112, a first drive wheel 113, a second motor 114, a second drive wheel 115, front and rear guide rails 116, left and right guide rails 117, a first driven wheel 118, a second driven wheel 119, and a rack and pinion belt 120. The front and rear guide rails 116 are disposed in the middle of the base plate 111 along a first direction. The left and right guide rails 117 are slidably disposed on the front and rear guide rails 116 along a second direction. The magnetic movable support plate 12 is slidably disposed on the left and right guide rails 117. The first end of the left and right guide rails 117 is provided with a first steering wheel 121 and a second steering wheel 122, and the second end of the left and right guide rails 117 is provided with a third steering wheel 123 and a fourth steering wheel 124. The first drive wheel 113... The first driven wheel 118 and the second driven wheel 119 are spaced apart along the second direction. The first motor 112 is connected to the first driven wheel 113, and the second motor 114 is connected to the second driven wheel 115. The first end of the rack belt 120 is connected to the left side of the magnetic moving tray 12. After being turned by the first steering wheel 121, the rack belt 120 engages with the first driven wheel 113 and the first driven wheel 118 in sequence, then is turned by the second steering wheel 122 and the fourth steering wheel 124, and then engages with the second driven wheel 119 and the second driven wheel 115 in sequence, and then is turned by the third steering wheel 123. The second end of the rack belt 120 is connected to the right side of the magnetic moving tray 12.
[0048] The first direction is the forward and backward direction, and the second direction is the left and right direction. When the first motor 112 and the second motor 114 rotate in opposite directions, they drive the magnetic moving tray 12 to move forward and backward. When the two motors 311 rotate in the same direction, they drive the magnetic moving tray 12 to move left and right.
[0049] Please see Figure 10 When the magnetic moving pallet 12 moves forward, the first motor 112 drives the first drive wheel 113 to rotate clockwise, and the second motor 114 drives the second drive wheel 115 to rotate counterclockwise. In this way, the middle of the rack belt 120 is taut and drags the left and right guide rails 117 to carry the magnetic moving pallet 12 forward along the front and rear guide rails 116. The first motor 112 and the second motor 114 have the same power, so that the magnetic moving pallet 12 is stationary relative to the left and right guide rails 117. The first end and the second end of the rack belt 120 are relaxed to buffer the resistance of the left and right guide rails 117 moving forward.
[0050] Please see Figure 10When the magnetic moving pallet 12 moves backward, the first motor 112 drives the first drive wheel 113 to rotate counterclockwise, and the second motor 114 drives the second drive wheel 115 to rotate clockwise. In this way, the first end and the second end of the rack belt 120 are tightened and drag the left and right guide rails 117 to move backward along the front and rear guide rails 116. The first motor 112 and the second motor 114 have the same power, so that the magnetic moving pallet 12 is stationary relative to the left and right guide rails 117, and the middle part of the rack belt 120 is relaxed to buffer the resistance of the magnetic moving pallet 12 moving backward.
[0051] Please see Figure 10 When the magnetic movable pallet 12 moves to the left, the first motor 112 drives the first drive wheel 113 to rotate counterclockwise, and the second motor 114 drives the second drive wheel 115 to rotate counterclockwise. In this way, the first end of the rack belt 120 is tightened, which drives the magnetic movable pallet 12 to move to the left along the left and right guide rails 117, and the second end of the rack belt 120 is relaxed to buffer the resistance of the magnetic movable pallet 12 moving to the left. The left and right guide rails 117 are limited by the front and rear guide rails 116, so that the left and right guide rails 117 are stationary relative to the front and rear guide rails 116.
[0052] Please see Figure 10 When the magnetic movable pallet 12 moves to the right, the first motor 112 drives the first drive wheel 113 to rotate clockwise, and the second motor 114 drives the second drive wheel 115 to rotate clockwise. In this way, the first end of the rack belt 120 is tightened, which drives the magnetic movable pallet 12 to move to the right along the left and right guide rails 117, and the second end of the rack belt 120 is relaxed to buffer the resistance of the magnetic movable pallet 12 moving to the right. The left and right guide rails 117 are limited by the front and rear guide rails 116, so that the left and right guide rails 117 are stationary relative to the front and rear guide rails 116.
[0053] Please see Figure 4 The first driving wheel 113, the second driving wheel 115, the first driven wheel 118, the second driven wheel 119, the rack belt 120, and the rack belt 120 are all located in the same plane. The first motor 112 is fixed above the first driving wheel 113, and the second motor 114 is fixed above the second driving wheel 115. This ensures that the sample loading waiting area 131, the sample mixing area 132, and the sample unloading area 133 are all relatively large.
[0054] Please see Figure 4 The first end and the second end of the rack belt 120 are fixed to the side of the magnetic movable support plate 12 by a fixing piece 125.
[0055] Please see Figure 4 The substrate 111 further includes a first limiting block 1111, a second limiting block 1112, a third limiting block 1113, a fourth limiting block 1114, and a position sensor 1115. The first limiting block 1111 is located near the first driving wheel 113 and corresponds to the rear end of the front and rear guide rails 116. The second limiting block 1112 is located near the first driven wheel 118 and corresponds to the front end of the front and rear guide rails 116.

The vertical connecting plate 3221 is connected to the snap-fit plate 321 on the side away from the sample removal area 133. The horizontal baffle 3222 is vertically connected to the vertical connecting plate 3221 and extends above the snap-fit plate 321. The horizontal baffle 3222 limits and blocks the blood collection tubes located in the blood collection tube slot 21 of the magnetic sample holder 2. The horizontal baffle 3222 is provided with a needle passage hole 3223 corresponding to the central axis of the blood collection tube slot 21. The outer shell 4 is connected to the horizontal base plate 13 and covers the flipping mixing device 3. The outer shell 4 is provided with a steel needle through hole 41 corresponding to the needle passage hole 3223. The steel needle through hole 41 and the needle groove hole 3223 facilitate the steel needle to be inserted into the blood collection tube slot 21 through the outer shell 4 to extract the sample, and then the steel needle is pulled out. The horizontal baffle 3222 prevents the blood collection tube from falling out of the blood collection tube slot 21.
[0057] Please see Figure 8 The first snap-fit structure 33 includes at least two guide snap-fit blocks 331. Each guide snap-fit block 331 includes a wedge-shaped guide portion 3311 and a snap-fit portion 3312. The width of the snap-fit portion 3312 is greater than the width of the wedge-shaped guide portion 3311.

The second snap-fit structure 22 includes a slide groove 221 and at least two limiting slots 222 located at the edge of the slide groove 221. The limiting slots 222 are correspondingly arranged with the guide snap-fit blocks 331. The guide snap-fit blocks 331 slide in the slide groove 221 so that the limiting slots 222 and the snap-fit portions 3312 engage or disengage with each other.
[0058] In use, after the magnetic sample holder 2 is transferred from the sample waiting area 131 to the sample mixing area 132, the magnetic moving tray 12 is used to attract and drag the magnetic sample holder 2 to move it to the rear end, so that the guide locking block 331 is located in the slide groove 221. The magnetic moving tray 12 is used to attract and drag the magnetic sample holder 2 to move it to the right, so that the guide locking block 331 slides in the slide groove 221 to make the limiting locking groove 222 and the locking part 3312 lock together. After the flipping bracket 32 flips to flip the magnetic sample holder 2 and shake the blood collection tube sample fixed on the magnetic sample holder 2 to mix, the sample is extracted by inserting a steel needle into the blood collection tube slot 21. The magnetic moving tray 12 is used to attract and drag the magnetic sample holder 2 to move it to the left, so that the magnetic sample holder 2 is detached from the flipping bracket 32. The magnetic moving tray 12 is used to attract and drag the magnetic sample holder 2 to move it to the front end to move it to the sample removal area 133, so that the blood collection tube from which the sample was extracted is removed.
[0059] The waiting-type cyclic sample loading device provided in this application embodiment enables the magnetic moving tray 12 to move in the horizontal plane by setting a horizontal transfer base 1 and using a translation drive mechanism 11. A horizontal base plate 13 is set parallel above the magnetic moving tray 12. A magnetic sample holder 2 is set on the horizontal base plate 13 and is attracted and dragged by the magnetic moving tray 12. The position of the magnetic sample holder 2 can be freely controlled. The magnetic sample holder 2 can be movably locked onto the flipping bracket 32 of the flipping mixing device 3 to flip the magnetic sample holder 2 to shake and evenly distribute the blood collection tube samples fixed on the magnetic sample holder 2. The magnetic sample holder 2 can also be attracted and dragged by the magnetic moving tray 12 to separate from the flipping bracket 32 of the flipping mixing device 3. This device can realize the integration of the blood collection tube sample loading process, reduce the space occupied by the equipment, and automate the waiting-type cyclic loading of multiple batches of blood collection tube samples, reducing manual operation and improving processing efficiency.
