Description

Technical Field

[0001] This application relates to the field of cell counter technology, and in particular to a chip transfer mechanism for a cell counter. Background Technology

[0002] As shown in the patent document with publication number CN219545910U, when using a cell counter, a chip containing a cell sample needs to be placed into the counter and then the concentration is detected.

[0003] During the chip transfer process, after the chip is inserted into the transfer channel, the drive component drives the two rotating rollers to rotate. The rotation of the two rotating rollers can drive the chip, thereby transferring the chip from one side of the two rotating rollers to the other side (specifically, for a cell counter, from outside the counter to inside the counter) to improve cell detection efficiency.

[0004] However, in microfluidic systems, the thickness and channel depth of the chip are crucial for fluid control and cell processing. The chip needs to have a specific thickness to accommodate microfabrication techniques such as photolithography and etching during the manufacturing process. Therefore, for chips of different thicknesses, the design limitations of the fixed rotating roller in this transfer mechanism are obvious. It is only suitable for transferring chips of the same thickness, which not only reduces practicality but also affects the cell capture efficiency.

[0005] Therefore, those skilled in the art have provided a chip transfer mechanism for a cell counter to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides a chip transfer mechanism for a cell counter.

[0007] The chip transfer mechanism for a cell counter provided in this application adopts the following technical solution:

[0008] A chip transfer mechanism for a cell counter includes:

[0009] Mounting bracket, and mounting plate fixedly mounted on one side thereof;

[0010] A transfer mechanism is disposed on the inner wall of the mounting frame and includes a rotating rod that passes through the bottom of the mounting frame. The rotating rod is rotatably connected to the mounting frame. A transfer roller and a pressure roller are sleeved on the inner surface of the rotating rod and a driving component is disposed on its top. A driving component is installed through the surface of the mounting frame to drive the transfer roller. A movable component is installed inside the mounting frame to adjust the spacing of the pressure roller. A stabilizing component is installed on one side inside the mounting frame. A chip body is disposed between the transfer roller and the pressure roller.

[0011] By adopting the above technical solution, the chip body can be automatically transferred, so as to maintain the detection efficiency of cells.

[0012] Preferably, the movable component includes a mounting opening on the surface of the mounting frame, a first slider is slidably mounted inside the mounting opening, the inner side of the first slider is fixedly connected to both ends of the pressure roller, a slide rod is fixedly mounted inside the mounting opening, the slide rod passes through the first slider and is slidably connected to it, and a first spring is fixedly mounted on the top of the first slider, the top end of the first spring is fixedly connected to the top of the inner cavity of the mounting opening.

[0013] By adopting the above technical solution, it is possible to transport chip bodies of different thicknesses, so as to avoid the situation where it is difficult to transfer when a specific thickness is required to support microfabrication technology, which would affect the cell capture efficiency.

[0014] Preferably, the driving component includes a motor mounted on the top of the inner side wall of the mounting frame, a reducer fixedly mounted on the output end of the motor, the output end of the reducer passing through the mounting frame and extending to the outside of the mounting frame, and pulleys fixedly mounted on one end of the rotating rod and one end of the reducer. A transmission belt is wound around the surface of the pulleys, and the two pulleys are connected by transmission belt.

[0015] By adopting the above technical solution, power can be provided for the rotation of the transfer roller, so as to facilitate the automated transfer of the chip body.

[0016] Preferably, the stabilizer includes two arc-shaped grooves formed on one side of the inner wall of the mounting bracket. A second spring is fixedly installed inside the arc-shaped groove. A second slider is fixedly installed at one end of the second spring. A clamping block is fixedly installed on one side of the second slider. One side of the clamping block is in contact with the top of the chip body.

[0017] By adopting the above technical solution, the stability of the chip body can be maintained during transfer, avoiding chip body shaking during transfer and affecting cell detection.

[0018] Preferably, a protective shell is fixedly installed on one side of the mounting bracket, and the protective shell is sleeved on the surface of the pulley and the transmission belt.

[0019] Preferably, the surfaces of the transfer roller and the pressure roller are covered with protective sleeves, and the protective sleeves are made of rubber components.

[0020] In summary, this application has the following beneficial technical effects:

[0021] 1. The chip transfer mechanism for the cell counter utilizes the elasticity of the first spring to drive the first slider downward when the chip body enters between the transfer roller and the pressure roller, thereby causing the pressure roller to descend and press the chip body, ensuring that the transfer roller can transfer the chip body when rotating. This enables the transfer of chip bodies of different thicknesses, avoiding the situation where the chip body is difficult to transfer when a specific thickness is required to support microfabrication technology, which would affect the cell capture efficiency.

[0022] 2. In the chip transfer mechanism for the cell counter, during the chip body transfer process, the clamping block can be tightened by the elasticity between the second spring and the second slider, so as to maintain the stability of the chip body during transport and avoid the chip body from tilting up during transfer, which would affect cell capture.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a chip transfer mechanism for a cell counter. (Refer to...) Figure 1-4 A chip transfer mechanism for a cell counter, comprising:

[0030] Mounting bracket 1, and mounting plate 2 fixedly mounted on one side thereof;

[0031] Reference Figure 1 as well as Figure 2 The transfer mechanism 3 is disposed on the inner side wall of the mounting frame 1 and includes a rotating rod 31 that passes through the bottom of the mounting frame 1. The rotating rod 31 is rotatably connected to the mounting frame 1. A transfer roller 32 is sleeved on the inner surface of the rotating rod 31 and a pressure roller 33 is disposed on its top. A driving member 34 is installed through the surface of the mounting frame 1 to drive the transfer roller 32. A movable component 35 is installed inside the mounting frame 1 to adjust the spacing of the pressure roller 33. A stabilizing member 36 is installed on one side inside the mounting frame 1. A chip body 37 is disposed between the transfer roller 32 and the pressure roller 33.

[0032] The drive unit 34 includes a motor 341 mounted on the top of the inner side wall of the mounting frame 1. A reducer 342 is fixedly mounted on the output end of the motor 341. The output end of the reducer 342 passes through the mounting frame 1 and extends to the outside of the mounting frame 1. A pulley 343 is fixedly mounted on one end of the rotating rod 31 and the reducer 342. A transmission belt 344 is wound around the surface of the pulley 343. The two pulleys 343 are connected by the transmission belt 344.

[0033] In this embodiment, the chip body 37 is inserted between the transfer roller 32 and the pressure roller 33, and the motor 341 is driven to work. The motor 341 uses the reducer 342 to drive the pulley 343 to rotate. When the pulley 343 rotates, it uses the transmission belt 344 to drive another pulley 343 to rotate, and simultaneously drives the rotating rod 31 and the transfer roller 32 to rotate, so as to automatically transfer the chip body 37.

[0034] Please continue to refer to Figure 1 A protective shell is fixedly installed on one side of the mounting bracket 1, and the protective shell is fitted onto the surface of the pulley 343 and the transmission belt 344; it can protect the pulley 343 and the transmission belt 344 and prevent dust or impurities from affecting the transmission of the two.

[0035] Reference Figure 2 as well as Figure 3 The active component 35 includes a mounting opening 351 on the surface of the mounting frame 1. A first slider 352 is slidably mounted inside the mounting opening 351. The inner side of the first slider 352 is fixedly connected to both ends of the pressure roller 33. A slide rod 353 is fixedly mounted inside the mounting opening 351. The slide rod 353 passes through the first slider 352 and is slidably connected to it. A first spring 354 is fixedly mounted on the top of the first slider 352. The top end of the first spring 354 is fixedly connected to the top of the inner cavity of the mounting opening 351.

[0036] In this embodiment, the elasticity of the first spring 354 drives the first slider 352 to slide downwards, and drives the pressure roller 33 to descend and press the chip body 37, so as to keep the transfer roller 32 maintaining pressure when rotating, so as to transfer chip bodies 37 of different thicknesses.

[0037] Reference Figure 3 as well as Figure 4 The stabilizer 36 includes two arc-shaped grooves 361 formed on one side of the inner wall of the mounting bracket 1. A second spring 362 is fixedly installed inside the arc-shaped groove 361. A second slider 363 is fixedly installed at one end of the second spring 362. A clamping block 364 is fixedly installed on one side of the second slider 363. One side of the clamping block 364 is in contact with the top of the chip body 37.

[0038] In this embodiment, the clamping block 364 can be tightened by the elasticity between the second spring 362 and the second slider 363, so as to always maintain the stability of the chip body 37 during transportation.

[0039] The surfaces of both the transfer roller 32 and the pressure roller 33 are covered with protective sleeves, and the protective sleeves are made of rubber.

[0040] The implementation principle of a chip transfer mechanism for a cell counter according to an embodiment of this application is as follows: When transferring the chip body 37, the chip body 37 is inserted between the transfer roller 32 and the pressure roller 33, and the motor 341 is driven to work. The motor 341 drives the pulley 343 to rotate using the reducer 342. When the pulley 343 rotates, it drives another pulley 343 to rotate using the transmission belt 344, and simultaneously drives the rotating rod 31 and the transfer roller 32 to rotate, thereby automatically transferring the chip body 37.

[0041] Furthermore, when the chip body 37 is inserted between the transfer roller 32 and the pressure roller 33, the elasticity of the first spring 354 can drive the first slider 352 to slide downwards, and drive the pressure roller 33 to descend and press the chip body 37, so as to keep the transfer roller 32 under pressure when it rotates.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
