[0048] In this embodiment, the carrier 34 is used to carry and install the main circuit board 50. The elastic support member 33 is a spring, and the elastic support member 33 is sandwiched between the needle plate 32 and the carrier 34, so that the carrier 34 can be installed on the needle plate 32 in a floating manner, that is, the carrier 34 can compress the elastic support member 33 to approach the needle plate 32. At this time, the test probe passes through the carrier 34 and abuts against the main circuit board 50, and the test probe forms an electrical connection with the main circuit board 50, so as to facilitate program burning and function testing of the main circuit board 50.

[0049] Specifically, Figure 5 and Figure 6As shown, a placement cavity 341 is provided on the top surface of the carrier 34, and the placement cavity 341 is used to accommodate and install the main circuit board 50. A positioning recess 342 is provided on the top surface of the carrier 34 on one side corresponding to the placement cavity 341, and one end of the positioning recess 342 is connected to the placement cavity 341, and the positioning recess 342 is used to install the key test module 36. A first through hole 343 is provided on the carrier 34 corresponding to the interior of the placement cavity 341; a second through hole 344 is provided in the middle of the needle plate 32, and the second through hole 344 corresponds to the first through hole 343, so that the optical coupler test module 35 can pass through the needle plate 32 and the carrier 34 and then connect to the main circuit board 50.

[0050] The optical coupling test module 35 includes a bracket 351 installed on the bottom surface of the needle plate 32, a lifting element 352 installed on the bracket 351, a support seat 353 connected to one end of the lifting element 352, a guide block 354 connected to the top surface of the support seat 353, and optical coupling stoppers 355 connected to opposite ends of the guide blocks 354. In this embodiment, the lifting element 352 is a cylinder, and the lifting element 352 is used to drive the guide blocks 354 to penetrate the second through hole 344 and the first through hole 343, and the guide blocks 354 and the optical coupling stoppers 355 are both connected to the main circuit board 50.

[0051] Specifically, Figure 7 As shown, the support seat 353 includes a first clamp block 3531 and a second clamp block 3532 which are arranged in parallel and spaced apart, and a lifting buffer 3533 which is clamped between the first clamp block 3531 and the second clamp block 3532. The first clamp block 3531 is connected to one end of the lifting element 352, and the second clamp block 3532 is used to carry and connect the guide block 354; the lifting buffer 3533 is a UR spring. When the guide block 354 and the optical coupling block 355 are connected to the main circuit board 50, the lifting buffer 3533 is squeezed by the second clamp block 3532 and the first clamp block 3531 to prevent the excessive driving force of the lifting element 352 from damaging the main circuit board 50.

[0052] The key test module 36 includes a fixing frame 361 installed on the top surface of the carrier 34, a pushing element 362 passing through the fixing frame 361, a pushing buffer 363 installed at one end of the pushing element 362, and a pushing head 364 connected to one end of the pushing buffer 363; the pushing element 362 is located in the positioning recess 342, and the pushing head 364 is used to abut the main circuit board 50. In this embodiment, the pushing element 362 is a cylinder, and the pushing buffer 363 is a UL5 spring. When the pushing head 364 abuts the main circuit board 50, the pushing buffer 363 can effectively reduce the impact force of the pushing element 362 on the main circuit board 50, so as to avoid the excessive pushing force of the pushing element 362 from damaging the main circuit board 50.

[0053] Furthermore, in this embodiment, if Figure 2 and Fig.10 As shown, the inner surfaces of the two opposite sides of the shield 37 are respectively connected with slide rails 371, the length direction of the slide rails 371 is consistent with the vertical direction, and the slide rails 371 are used for sliding connection with the upper mold assembly 40. In this embodiment, the vertical transmission element 38 is a cylinder; the vertical transmission element 38 includes a vertical transmission element body and a vertical transmission rod movably installed in the vertical transmission element body; wherein the vertical transmission element body is installed on the bottom surface of the panel 31, and the vertical transmission rod is connected to the upper mold assembly 40 after passing through the panel 31 to drive the upper mold assembly 40 to slide vertically.

[0054] like Fig.10 As shown, the upper mold assembly 40 includes a lifting plate 41, sliders 42 installed on opposite sides of the lifting plate 41, two pressure columns 43 connected to the middle of the bottom surface of the lifting plate 41, two limit pins 44 connected to one end of the bottom surface of the lifting plate 41, a clamping module 45 installed on the top surface of the lifting plate 41, and a fixture 46 installed on the bottom surface of the lifting plate 41; wherein, the vertical transmission rod passes through the panel 31 and then connects to the lifting plate 41. The clamping module 45 is used to clamp the reagent kit 60, and the fixture 46 is used to accommodate the reagent kit 60. The slider 42 matches the connecting slide rail 371, so that the lifting plate 41 is slidably connected to the shield 37. The pressure column 43 is used to abut the main circuit board 50, and the limit pin 44 is used to abut the panel 31.

[0055] A through hole 410 having a generally rectangular shape is provided at one end of the lifting plate 41, and the through hole 410 is used for the clamping module 45 to pass through. The clamping module 45 includes a clamping drive 47 mounted on the lifting plate 41, a clamping block 48 connected to one end of the clamping drive 47, and a distance sensor 49 mounted on a side of the clamping drive 47 facing away from the lifting plate 41; the distance sensor 49 is used to detect the position of the clamping block 48 to prevent the clamping block 48 from moving excessively and causing damage to the entire upper mold assembly 40. The clamping block 48 is connected to the reagent kit 60 after passing through the through hole 410.

[0056] In the present embodiment, the clamping drive 47 is a cylinder. The clamping drive 47 includes a clamping drive body mounted on the lifting plate 41, and a clamping piston rod movably mounted in the clamping drive body; the moving direction of the clamping piston rod is consistent with the length direction of the through hole 410. Among them, the end of the clamping piston rod away from the clamping drive body is used to connect the clamping block 48 to drive the clamping block 48 to move. Specifically, a clamping opening 480 is provided on one side of the clamping block 48 facing the reagent kit 60, and the clamping opening 480 is used to accommodate the reagent kit 60. In actual use, the reagent kit 60 is clamped on the clamping block 48, and the clamping drive 47 is started to drive the reagent kit 60 to move toward the jig 46 until the reagent kit 60 is inserted into the jig 46.

[0057] The jig 46 is hollow, and a docking port 461 is provided on one side of the jig 46 facing the reagent kit 60, and the docking port 461 is connected to the interior of the jig 46, and the docking port 461 is used for the reagent kit 60 to pass through, so that the reagent kit 60 is inserted into the interior of the jig 46. Furthermore, a jig slot 462 is provided on one end of the jig 46 away from the docking port 461, and the jig slot 462 is located on the side of the jig facing away from the lifting plate 41, and the jig slot 462 is connected to the interior of the jig 46.

[0058] like Figure 8 and Fig. 9 As shown, the main circuit board 50 is used to be installed in the placement cavity 341, and the main circuit board 50 includes a substrate 51, two optical coupling sensors 52 installed on the bottom surface of the substrate 51, a key module 53 installed on one side of the substrate 51, and a connector 54 installed on the top surface of the substrate 51. Among them, the optical coupling sensor 52 is used for the optical coupling block 355 to be inserted, and the key module 53 is used to abut the push head 364.

[0059] Specifically, a limiting hole 55 is provided in the middle of the substrate 51, and the limiting hole 55 corresponds to the first through hole 343; two optical coupling sensors 52 are located on opposite sides of the limiting hole 55. In actual use, the guide block 354 is correspondingly penetrated by the second through hole 344, the first through hole 343 and the limiting hole 55 to achieve clamping and fixing of the main circuit board 50, and the optical coupling block 355 is correspondingly inserted into the inside of the optical coupling sensor 52. Since the gap inside the optical coupling sensor 52 is small and the thickness of the substrate 51 is small, the optical coupling test module 35 uses a UR spring as a lifting buffer 3533, which can prevent the excessive driving force of the lifting element 352 from causing bending and deformation of the substrate 51, resulting in the breakage of the solder joints of various parts on the substrate 51, so that the function of the main circuit board 50 is damaged.

[0060] In this embodiment, the optical coupling sensors 52 are arranged in an “n” shape.

[0061] like Fig.12 As shown, the reagent kit 60 includes a reagent kit body 61, a reagent kit circuit board (not shown) installed in the reagent kit body 61, and a gold finger (not shown) installed at one end of the reagent kit circuit board. A reagent kit slot 62 is provided at one end of the reagent kit body 61 close to the jig 46. The reagent kit slot 62 is located on the side of the reagent kit body 61 facing away from the lifting plate 41. The reagent kit slot 62 corresponds to the gold finger to expose the gold finger. During the test, the reagent kit 60 is inserted into the jig 46, and the reagent kit slot 62 overlaps with the jig slot 462. Then, the entire upper mold assembly 40 approaches the lower mold assembly 30 until the connector 54 penetrates the jig slot 462 and the reagent kit slot 62 and docks with the gold finger. The connector 54 is electrically connected to the gold finger for electrical performance testing.

[0062] The above-mentioned blood analyzer function test device has a reasonable structure and complete functions. It uses a test probe to abut the main circuit board 50, and moves the reagent box 60 close to the lower mold assembly 30. The reagent box circuit board is connected to the main circuit board 50, which can effectively test the function of the blood analyzer and ensure the quality of the blood analyzer.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
