Description

Technical Field

[0001] The present invention relates to a disk transfer structure. Background Art

[0002] Due to the convenience of reagent disks in the field of modern medical testing, their importance is increasing. For example, in Chinese patents with publication numbers such as CN111308107A and CN211235880U, there are currently a large number of patents related to reagent disks. In the actual use process, it is necessary to take out a new disk and move it to the working position. When the disk becomes a waste disk after use, it is also necessary to move the waste disk to the waste disk storage position. If an automated disk transfer structure can be designed, it can greatly save the required manpower. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a disk transfer structure that can achieve the automated transfer of actual disks.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A disk transfer structure includes a new disk compartment, a waste disk compartment, a support rod disposed between the new disk compartment and the waste disk compartment, a baffle plate rotatably disposed at the bottom end on the support rod, and a grasping device for grasping the reagent disk; a support portion is provided on the support rod on the side close to the new disk compartment, so that the baffle plate inclines towards the new disk compartment side.

[0006] Further, an upwardly convex arc portion is provided at the lower end of the top surface of the baffle plate.

[0007] Further, the grasping device includes a mounting plate, a position sensing device disposed on the mounting plate, and a grasping mechanism that is in signal communication with the position sensing device for grasping the reagent disk.

[0008] Further, the position sensing device includes an opto-coupler flap rotatably disposed at one end on the mounting plate and a corner opto-coupler disposed above the opto-coupler flap for detecting the position signal of the opto-coupler flap; a torsion spring is provided on the rotating shaft of the opto-coupler flap to keep the opto-coupler flap in contact with the bottom mounting plate; a contact rod for contacting the reagent disk is provided at the other end of the opto-coupler flap.

[0009] Further, a support rod is provided at the upper end of the opto-coupler flap, and the support rod cooperates with the corner opto-coupler to achieve position detection.

[0010] Further, the grasping mechanism includes a central shaft mounted on the mounting plate, two or more struts that are in clearance fit on the mounting plate and surround the outside of the central shaft, and a driving device for moving the bottom ends of the struts inward and outward. The axis lines of the plurality of struts are located on the same circle and are concentric with the central shaft.

[0011] Further, the driving device includes a paddle, paddle holes provided on the paddle and corresponding to the number of struts, and a rotary driving mechanism for driving the paddle to rotate; the center of the paddle is sleeved on the central axis, the paddle holes are oblong, and the long axis of the paddle holes is arranged at an angle to the radial direction of the paddle, and the struts pass through the corresponding paddle holes.

[0012] Further, the rotary driving mechanism includes an electromagnetic push rod installed on the mounting plate, a connecting rod connected to the electromagnetic push rod, and a fitting hole provided on the paddle for cooperating with the connecting rod.

[0013] Further, a base circle is fixedly installed on the central axis, and base circle holes corresponding to the struts are provided on the base circle, and the long axis of the base circle holes gradually extends outward from the center of the base circle.

[0014] Further, a spherical portion for cooperating with the central hole of the reagent tray is provided at the bottom of the central axis, and a relief groove corresponding to the strut is formed on the spherical portion.

[0015] The positive effects of the present invention are as follows: The present invention utilizes the baffle provided before the new tray compartment and the waste tray compartment to play a guiding role. When grasping a new tray upward, the baffle can rotate towards the waste tray compartment side, but will not reach the vertical position of the baffle, so that the baffle is used in a position biased towards the new tray compartment side. When a waste tray needs to be placed, the grasping device directly releases, and the waste tray will fall above the baffle and gradually slide downward under the action of gravity, thereby entering the waste tray compartment, realizing the automatic grasping of new trays and the recycling of waste trays, without manual operation.

[0021] As shown in the atta Figure 1As shown in the figure, the present invention includes a base, a new disc chamber 3 and a waste disc chamber 2 provided on the base, a support rod 7 provided between the new disc chamber 3 and the waste disc chamber 2, a baffle 4 whose bottom end is rotatably mounted on the support rod 7 through a rotating shaft, and a grasping device 1 for grasping the reagent disc. The grasping device 1 is installed on a power source that can move vertically up and down. This power source only needs to be able to complete the vertical up and down movement of the grasping device 1. Such a power source is relatively common at present and will not be elaborated here.

[0022] On one side of the support rod 7 close to the new disc chamber 3, there is a support portion that can resist the baffle 4, making the side of the baffle 4 facing the new disc chamber 3 tilt upward. An arc-shaped opening is provided at the bottom of the baffle 4. When the reagent disc moves upward, the baffle 4 will block the moving direction of the reagent disc. The reagent disc will drive the baffle 4 to rotate towards the waste disc chamber 2 side, but will not completely flip to the waste disc chamber 2 side. After the reagent disc is completely taken out, the baffle 4 will fall back to the initial position, that is, the position in contact with the support portion. An upwardly convex arc-shaped portion 6 is provided at the lower end of the top surface of the baffle 4, making the top surface of the baffle 4 form a slideway. When it is necessary to recycle the waste disc, the grasping device 1 releases the waste disc from above the baffle 4. The waste disc falls onto the baffle 4 and slides down under the action of gravity, passes through the arc-shaped portion 6 and enters the waste disc chamber 2 to realize the recycling of the waste disc. The cross-sections of the new disc chamber 3 and the waste disc chamber 2 are both in a shape corresponding to the reagent disc.

[0023] As shown in the appendix Figure 2 As shown in the figure, the grasping device 1 includes a mounting plate 101, a position sensor provided on the mounting plate 101, and a grasping mechanism that is in signal communication with the position sensor and is used to grasp the reagent disc. When the position sensor senses that the grasping mechanism can grasp the reagent disc, it sends a grasping signal to the grasping mechanism to grasp the reagent disc and then lift it.

[0024] The position sensing device includes an optocoupler baffle 110 rotatably arranged at one end on the mounting plate 101 and a corner optocoupler 111 arranged above the optocoupler baffle 110 to detect the position signal of the optocoupler baffle 110. A torsion spring 112 is arranged on the rotating shaft where the optocoupler baffle 110 cooperates with the mounting plate 101. In the initial state, under the action of the torsion spring 112, the optocoupler baffle 110 deflects downward, so that the optocoupler baffle 110 remains in contact with the bottom mounting plate 101, and the corner optocoupler 111 is separated from the optocoupler baffle 110. When the mounting plate 101 moves downward and the optocoupler baffle 110 touches the reagent tray, as the mounting plate 101 continues to move downward, the optocoupler baffle 110 is forced to deflect upward until the optocoupler baffle 110 blocks the corner optocoupler 111, realizing position detection. At this time, the grasping mechanism is also exactly at the position where it can grasp the reagent tray, and the corner optocoupler 111 sends a grasping signal to the grasping mechanism. As a further improvement of this patent, a downward contact rod is connected to the free end of the optocoupler baffle 110 for contacting the reagent tray, and a vertically upward support rod is arranged at the upper end of the optocoupler baffle 110. The position of the support rod corresponds to that of the corner optocoupler 111. When the optocoupler baffle 110 deflects, the support rod enters the position of the corner optocoupler 111 to trigger a signal.

[0025] As shown in the Figure 2-5 accompanying drawings, the grasping mechanism includes a cross plate fixed on the mounting plate 101, a central shaft 103 fixed on the cross plate, a spherical part 116 arranged at the bottom of the central shaft 103 and used for cooperating with the central hole of the reagent tray, more than two support rods 104 (in this embodiment, the number of support rods 104 is 3) installed on the cross plate with a clearance fit and located around the central shaft 103, and a driving device located at the bottom end of the support rods 104 for moving the bottom ends of the support rods 104 inward and outward; the plurality of support rods 104 are located on the same circle, and the center of this circle is located on the axis of the central shaft 103.

[0026] The driving device includes a dial 106 sleeved on the central shaft 103, dial holes 113 arranged on the dial 106 and corresponding to the number of support rods 104, and a rotary driving mechanism for driving the dial 106 to rotate. The bottom ends of the support rods 104 pass through the dial holes 113. The dial holes 113 are oblong and the long axis thereof is arranged at an angle with the radial direction of the dial 106. That is, when the dial 106 rotates, under the action of the dial holes 113, the plurality of support rods 104 can move inward or outward simultaneously in the dial holes 113. A relief hole corresponding to the support rod 104 is arranged on the spherical part 116. When the plurality of dials 106 rotate in one direction so that the bottom ends of the support rods 104 move to the innermost position, the support rods 104 enter the position of the relief hole and can smoothly pass through the central hole of the reagent tray. Then the dial 106 rotates in the reverse direction to make the support rods 104 move outward simultaneously and fit tightly on the inner wall of the central hole of the reagent tray. By moving the mounting plate 101 upward, the reagent tray can be lifted.

[0027] Those skilled in the art will know that it is necessary to appropriately adjust the deflection trigger position of the optical coupling baffle 110 so that when the corner optical coupling 111 receives the signal, the bottom of the support rod 104 corresponds exactly to the center hole of a reagent disk, so as to facilitate the capture of only one reagent disk at a time.

[0028] The driving mechanism includes an electromagnet push rod 109 fixed on the mounting plate 101, a connecting rod 108 connected to the electromagnet push rod 109, and an assembly hole 114 set on the paddle 106. One end of the connecting rod 108 is hook-shaped and hooked into the assembly hole 114 to achieve connection. The electromagnet push rod 109 drives the connecting rod 108 to move back and forth, thereby realizing the forward and reverse rotation of the paddle 106.

[0029] A base circle 107 is also fixedly mounted on the central axis 103, and a base circle hole 115 corresponding to the strut 104 is provided on the base circle 107. The bottom of the strut 104 passes through the base circle hole 115, and the long axis of the base circle hole 115 gradually extends outward from the center of the base circle 107 (in this embodiment, the long axis of the base circle hole 115 is arranged radially). The strut 104 can only move within the base circle hole 115. The base circle hole 115 is used in conjunction with the paddle hole 113. When the paddle rotates, the strut 104 moves inward or outward at the same time.

[0030] In this embodiment, the base circle 107 is located above the spherical portion 116, the paddle 106 is located above the base circle 107, and a lower pressing plate 105 is provided above the paddle 106 to press the paddle 106 to prevent the paddle 106 from jumping during rotation.

[0031] During use, the gripping device 1 is driven by a power source and moves vertically downward. As the gripping device 1 moves downward, when the optical coupler baffle touches the reagent disk, it deflects upward, triggering a corner optical coupler signal. Upon detecting that the disk is in place, the electromagnet push rod 109 contracts, driving the paddle 106 to rotate, causing the support rod to move outward, supporting the disk. The gripping device 1 then moves upward to its working position. The tray (not shown) in the working position moves to a position below the disk. The electromagnet push rod 109 contracts and extends, causing the paddle 106 to return to its original position, releasing the disk onto the tray. When the disk is used and becomes waste, the gripping device 1 grabs the waste disk, the tray returns to its original position, and the gripping device 1 releases the waste disk. The waste disk then slides along the chute above the baffle 4 into the waste disk compartment 2.
