[0002] In various medical tests, test strips are used for testing, and the test strips are fixed in the card slots of the tray. After the test, the test strips need to be taken out of the tray so that the tray can be reused.

[0003] In the automated testing equipment, the utility model patent with the authorization announcement CN214779145U discloses a structure for automatically separating the reagent strip from the tray. In this structure, the position of the unloading plate is fixed, the tray is grasped by the tray clamp, and the tray grasped by the tray clamp is moved to the unloading plate by the moving mechanism to separate the reagent strip from the tray.

[0004] In this structure, after the blanking plate contacts the reagent strip, it will apply pressure to the tray clamp and the moving mechanism, while the tray clamp is in a suspended state. Therefore, frequent application of pressure will have an adverse effect on the long-term use of the tray clamp and the structure that drives the clamp to flip, increasing the failure rate of the equipment.

[0030] Example 1

[0031] The reagent strip return device disclosed in the utility model is described below in conjunction with the accompanying drawings. Figure 1 As shown, it includes:

[0032] The tray positioning device 100 is used to carry and position the tray 500 containing the reagent strip 400;

[0033] The stripping plate 200 is disposed above the tray positioning device 100 and is used to strip the reagent strip 400 on the tray 500 at the tray positioning device 100;

[0034] The material stripping driving device 300 is connected to the material stripping plate 200 and drives the material stripping plate 200 to move up and down to realize the material stripping of the reagent strip 400 on the tray 500 at the tray positioning device 100 .

[0035] During operation, the tray 500 loaded with the reagent strips 400 is placed on the tray positioning device 100 with the bottom facing upward, and then the material stripping plate 200 is driven downward by the material stripping driving device 300. The material stripping plate contacts the reagent strips 400 on the tray 500 and applies downward pressure to different reagent strips 400 step by step, so that the reagent strips 400 at different positions are separated from the tray 500 in turn to realize material stripping.

[0036] The specific structure of the tray positioning device 100 can be designed as needed, and includes two side panels 110 that are spaced and opposite to each other. The two sides of the two side panels can have inwardly bent portions to support the tray 500. Of course, the tops of the two side panels can also be provided with inwardly bent support plates, and the support plates are provided with limit columns or pins that match the holes or grooves on the tray 500, so as to achieve the positioning of the tray 500. At the same time, a baffle 120 can also be provided on the same side of the two side panels to assist in the positioning of the tray. Further, the tray positioning device 100 includes a feed channel 130 below the tray 500 located thereon, and the feed channel 130 is formed by the two side panels and the baffles vertically arranged on both sides of the two side panels. The reagent strip 400 and the probe assembly 900 separated from the tray 500 can enter the collection tank connected to the feed channel 510 through the feed channel 130.

[0037] Furthermore, a limit plate 140 can be arranged above the two side plates, and the limit plate 140 is located outside the two side plates, and the lower side of each limit plate 140 is connected to the side plate through an inclined plate, so as to play a certain role in limiting and guiding.

[0038] As attached Figure 1 As shown, there are multiple stripping plates 200, preferably two, and their specific installation positions can be designed and adapted according to the specific tray 500, which is not limited here.

The bottom of the stripper plate is formed with steps, and the height of the step surface 220 of the step increases from the middle to both sides. Each stripper protrusion 210 is arranged below a step surface 220, and the height of any two step surfaces is different. In addition, except for the two outermost stripper protrusions 210, the other stripper protrusions are located in the middle of the step surface.

[0041] As attached Figure 1 As shown, the adapter frame 600 is also provided with a push pin plate 700 parallel to the stripper plate 200. The connection method of the push pin plate 700 and the adapter frame 600 is the same as the connection method of the stripper plate 200 and the adapter frame 600, which will not be described in detail here. The push pin plate 700 includes a row of push rods 710 arranged at intervals, and the push rods 710 are arranged at equal intervals, and each push rod corresponds to a probe assembly 900 on the tray.

[0042] As attached Figure 1 , Attachment Figure 2 As shown, the material-removing driving device 300 may be a known device or structure capable of driving the adapter frame 600 to move up and down, for example, it may be a cylinder, a hydraulic cylinder, a linear module, etc. Preferably, in order to reduce costs, the material-removing driving device 300 may adopt a structure in which a motor 310 and a lead screw 320 cooperate, that is, the motor 310 is connected to the lead screw 320, and the movable nut of the lead screw 320 is connected to the adapter frame 600, and the adapter frame 600 is arranged on the stand frame through the sliding frame 330 and the guide rail assembly 340. At the same time, the motor 310 and the lead screw 320 are located between the stand frame and the pallet positioning device 100, and can be better protected.
