[0044] The following description sets forth many specific details to facilitate a full understanding of the present invention, but the present invention may also be implemented in other variations or alternatives based on these details. Other possible implementations that may be known to those skilled in the art based on the embodiments described herein are all within the scope of protection of the present invention.

[0045] like Figures 1-3As shown, the reagent kit assembly equipment of the embodiment includes an assembly conveyor belt 10, a lower shell feeding mechanism 21, and an upper shell feeding mechanism 31; wherein, there are preferably two assembly conveyor belts 10, the two assembly conveyor belts are arranged side by side in the Y direction, and the lower shell feeding mechanism 21 and the upper shell feeding mechanism 31 are respectively located at the opposite ends of the assembly conveyor belt 10 in the X direction.

[0046] In the embodiment, Figure 4 As shown, the lower shell feeding mechanism 21 includes a feeding vibration plate 211, a hopper 212 and a lifting conveyor belt 213. The lower shells stored in the hopper 212 are fed into the inner cavity of the feeding vibration plate 211 by the lifting conveyor belt 213, and the lower shells in the inner cavity of the feeding vibration plate 211 are transported along the spiral track 214. The lower shells with set postures (set positive and negative and front and back directions) on the spiral track 214 are output through the feeding outlet of the feeding vibration plate 211 (that is, the feeding outlet of the lower shell feeding mechanism 21), and the lower shells without set postures return to the inner cavity of the feeding vibration plate 211.

[0047] In an optional embodiment, the feeding vibration disk 21 is equipped with a detection camera, and the posture of the lower shell transported by the spiral track 214 can be identified by the detection camera. The lower shell that does not have a set posture is blown / pushed back from the spiral track 214 to the inner cavity of the feeding vibration disk 211, and the lower shell with a set posture can be output from the feeding outlet of the feeding vibration disk 211.

[0048] The structural design of the upper shell feeding mechanism 31 can refer to the lower shell feeding mechanism 21 and will not be described in detail.

[0049] like Figure 5 As shown, the assembly conveyor belt 10 is provided with a test strip installation station 10a and an upper shell installation station 10b, and the lower shell supplied by the lower shell feeding mechanism 21 is sequentially transported by the assembly conveyor belt 10 to the test strip installation station 10a and the upper shell installation station 10b. Preferably, the test strip installation station 10a and the upper shell installation station 10b are both provided with a lifting positioning mechanism, which includes a positioning frame 11 and a lifting drive device (such as a lifting cylinder) connected to the positioning frame 11. The positioning frame 11 is used to position the lower shell on the assembly conveyor belt 10 to facilitate accurate installation of the test strip and the upper shell. In an embodiment, the positioning frame 11 has a positioning hole that is compatible with the lower shell. When the test strip and the upper shell are installed, the positioning frame 11 descends so that the lower shell enters the positioning hole to position the lower shell.

[0050] Further, if Figure 3As shown, the feed outlet of the lower shell feeding mechanism 21 is provided with a lower shell feeding conveyor belt 22, and the feed outlet of the upper shell feeding mechanism 31 is provided with an upper shell feeding conveyor belt 32. The lower shell feeding conveyor belt 22 and the upper shell feeding conveyor belt 32 are both arranged between the two assembly conveyor belts 10. The lower shell on the lower shell feeding conveyor belt 22 can be transferred to the two assembly conveyor belts 10 by the lower shell loading robot 23, and then transported by the assembly conveyor belts 10 to the test strip installation station 10a and the upper shell installation station 10b. The upper shell on the upper shell feeding conveyor belt 32 can be transferred to the upper shell installation station 10b by the upper shell installation robot 33 for installation. Preferably, the test kit assembly equipment is also equipped with a detection camera for detecting the posture of the upper shell on the upper shell feeding conveyor belt 32 and the lower shell on the lower shell feeding conveyor belt 32.

[0051] In the embodiment, Figure 6 As shown, the lower shell loading robot 23 includes two independently working negative pressure adsorption parts 231, and the two negative pressure adsorption parts 231 can move independently in the Y direction and the Z direction to transfer the lower shell on the lower shell feeding conveyor belt 22 to the two assembly conveyor belts 10 respectively. The upper shell installation robot 33 has the same structure as the lower shell loading robot 23 and also includes two independently working negative pressure adsorption parts 331, and the two negative pressure adsorption parts 331 can move independently in the Y direction and the Z direction to transfer the upper shell on the upper shell feeding conveyor belt 32 to the upper shell installation stations 10b of the two assembly conveyor belts 10 respectively, and install the upper shell on the lower shell at the upper shell installation station 10b. In other embodiments of the present invention, the negative pressure adsorption parts 231 and 331 can also be replaced by clamping parts such as claws.

[0052] Further, if Figures 1-3 As shown, the two assembly conveyor belts 10 are each provided with a test strip feeding and cutting mechanism 40, a test strip pan manipulator 50, a test strip intermediate turntable 60, and a test strip installation manipulator 70 on the opposite sides thereof. The test strip intermediate turntable 60 is rotatably disposed between the test strip feeding and cutting mechanism 40 and the assembly conveyor belt 10. The test strip intermediate turntable 60 has a plurality of accommodating slots 61 (see FIG. 1 ) arranged along its circumference for accommodating test strips. Figure 7 ), the test strip pan robot 50 is used to place the test strips cut by the test strip feeding and cutting mechanism 40 into the corresponding receiving slots 61 of the test strip intermediate turntable 60, and the test strip installation robot 70 is used to install the test strips on the test strip intermediate turntable 60 into the lower housing at the test strip installation station 10a. In this embodiment, the test strip installation robot 70 can also be positioned between the test strip feeding and cutting mechanism 40 and the assembly conveyor 10 in the Y direction.

[0053] Further, if Figure 7 and8 As shown, the test strip feeding and cutting mechanism 40 includes a cutting mechanism 42 and a test paper feeding mechanism 41 disposed above the cutting mechanism 42. The test paper feeding mechanism 41 is used to stack and store the test papers 103 to be cut, and the cutting mechanism 42 is used to cut the test paper 103 into test strips for installation in the lower housing. Figure 9 As shown, the test paper feeding mechanism 41 includes a base plate 410 with a feed hole 411. Multiple levers 413 are positioned along the edges of the feed hole 411 on the base plate 410. These levers 413 are used to laterally limit the stored test paper 103 to be cut. Furthermore, horizontal support cylinders 412 are mounted on at least two opposing sides of the feed hole 411. The support cylinders 412 radially protrude into the feed hole 411 to support the test paper 103 stored in the feed mechanism 41. When the test paper 103 enters the cutting mechanism 42 through the feed hole 411, the edges of the test paper 103 are protected from scratches by the support cylinders 412.

[0054] like Figure 10 and 11 As shown, the cutting mechanism 42 includes a feed guide 421, a negative pressure suction nozzle 4221, a pushing mechanism 423, and a cutter 424. The negative pressure suction nozzle 4221 is arranged to be raised and lowered to suck and pull the test paper 103 to be cut in the test paper feeding mechanism 41 onto the supporting step 4211 of the feed guide 421. Specifically, the negative pressure suction nozzle 4221 can be installed on the lifting bracket 4222 located on the opposite sides of the feed guide groove 421, and the lifting bracket 4212 is connected to the lifting cylinder 4223 to perform lifting movement; when working, the lifting bracket 4222 first rises to a predetermined height, so that the negative pressure suction nozzle 4221 can adsorb a piece of test paper 103 stacked at the bottom of the test paper feeding mechanism 41, and then the lifting bracket 4222 descends. When the test paper 103 is supported by the supporting step 4211 of the feed guide groove 421, the negative pressure suction nozzle 4221 releases the adsorption of the test paper 103, and the test paper unloading operation is completed.

[0055] The pushing mechanism 423 is used to push the test paper on the supporting step 4211 toward the cutter 424. In the embodiment, the pushing mechanism 423 includes a clamping portion 4231, a translation bracket 4232, a screw 4233 and a motor 4234. Among them, the clamping portion 4231 can clamp one end of the test paper relative to the cutter 424, and the screw 4233 and the translation bracket 4232 are threadedly connected to form a screw translation mechanism, and the screw 4233 can rotate under the drive of the motor 4234 to move the translation bracket 4232 along the X direction. When the clamping portion 4231 moves toward the cutter 424 together with the translation bracket 4232, the test paper on the supporting step 4211 will be fed toward the cutter 424, and the cutter 424 will cut the test paper into test strips. Further, asFigure 7 As shown, the test strip feeding and cutting mechanism 40 further includes a waste box 43 , which is disposed below the cutter 424 and is used to collect unqualified cut products.

[0056] In the embodiment, Figure 12 As shown, the test strip swing plate robot 50 includes a first test strip pick-up and placement assembly 51 and a swing plate drive mechanism 52. The first test strip pick-up and placement assembly 51 includes two first grippers 511 that can open and close vertically (in the Z direction). The swing plate drive mechanism 52 includes a first mounting base 521, a first movable base 522, a first swing arm 523, and a first motor 524. The first test strip pick-up and placement assembly 51 can also use a negative pressure suction structure that can absorb the test strip, such as a negative pressure suction nozzle or suction cup.

[0057] The first test strip pick-up and placement assembly 51 is mounted on the first movable seat 522 in a liftable manner. Figure 8 As shown, a lifting drive device such as a lifting cylinder 53 is provided on the first movable base 522 , and the first test strip picking and placing assembly 51 is connected to the lifting cylinder 53 to perform lifting motion.

[0058] The first movable base 522 slides with the first mounting base 521 in the X and Y directions, allowing the first test strip pick-and-place assembly 51 to move in a horizontal plane. In an embodiment, a cross-slider connection mechanism 525 may be provided between the first movable base 522 and the first mounting base 521 to enable the first movable base 522 to slide with the first mounting base 521 in the X and Y directions.

[0059] The first swing arm 523 and the first movable seat 522 form a rotational sliding engagement in a horizontal plane. In this embodiment, a first roller 5221 is provided at the bottom of the first movable seat 522, and the first swing arm 523 is provided with a strip groove 5231. The first roller 5221 is disposed within the strip groove 5231, thereby achieving a rotational sliding engagement between the first swing arm 523 and the first movable seat 522.

[0060] Furthermore, a first track groove 5211 is provided on the first mounting base 521, and a first roller 5221 is disposed in the first track groove 5211. The cooperation between the first roller 5221 and the first track groove 5211 can define the motion track of the first movable seat 522. The first track groove 5211 includes a first Y guide groove 5211Y and an X guide groove 5211X disposed at both ends of the first Y guide groove 5211Y. When the first swing arm 523 is driven by the first motor 524 to rotate horizontally, the first movable seat 522 and the first test strip pick-up and placement assembly 51 can move along the first Y guide groove 5211Y and the X guide groove 5211X, so that the first test strip pick-up and placement assembly 51 can be positioned to pick up a test strip from the test strip feeding and cutting mechanism 40 (see FIG. 1 ). Figure 7) and placing the test strip on the test strip turntable 60 (see Figure 8 ) between movements.

[0061] The test strips on the test strip turntable 60 can be placed into the lower housing of the reagent kit by the test strip installation robot 70 at the test strip installation station 10a. Figures 13 to 15 As shown, the test strip installation robot 70 includes a second test strip picking and placing assembly 71 and a test strip installation drive mechanism, and the test strip installation drive mechanism is used to drive the second test strip picking and placing assembly 71 to move between a position for picking up a test strip from the test strip turntable 60 and a position for installing the test strip into the lower shell (i.e., the lower shell installation station 10b).

[0062] In this embodiment, the test strip installation and drive mechanism includes a second mounting base 721 having a box structure, a second movable base 722, a connecting rod 723, a second swing arm 724, and a second motor 725. The second test strip placement assembly 71 is mounted on the second movable base 722. The second movable base 722 is generally L-shaped, with its horizontal portion disposed outside the second mounting base 721 and its vertical portion partially disposed outside the second mounting base 721.

[0063] The second movable seat 722 slides with the second mounting base 721 in the Y and Z directions. In an embodiment, a cross-slider connection mechanism 725 can be provided between the first side wall 7211 of the second mounting base 721 and the second movable seat 722 to achieve sliding cooperation between the second movable seat 722 and the second mounting base 721 in the Y and Z directions.

[0064] Furthermore, a second tracking groove 7213 is formed on the first sidewall 7211 of the second mounting base 721. The second tracking groove 7213 includes a second Y-direction guide groove 7213Y and a Z-direction guide groove 7213Z disposed at either end of the second Y-direction guide groove 7213Y. The second movable base 722 has a second roller 7221 disposed within the second tracking groove 7213. The second roller 7221 cooperates with the second tracking groove 7213 to define the motion trajectory of the first movable base 522.

[0065] In this embodiment, the connecting rod 723 has opposite ends rotatably connected to the second side wall 7212 of the second mounting base 721 and the second movable base 722, respectively. The second side wall 7212 rotatably engages with one end of the connecting rod 723 to form a rotation fulcrum 7231. The second side wall 7212 is disposed opposite the first side wall 7211. The connecting rod 723 and the second rocker arm 724 form a sliding engagement within a vertical plane. For example, the connecting rod 723 may be provided with a slide groove, and the second rocker arm 724 may be provided with a slide rail that engages with the slide groove.

[0066] The second swing lever 724 can be driven by the second motor 725 to rotate in a vertical plane. When the second swing lever 724 rotates, the connecting rod 723 will rotate around the rotating pivot point 7231, so that the second moving seat 722 and the second test strip taking and placing assembly 71 can move along the second Y-direction guide slot 7213Y and the Z-direction guide slot 7213Z, thereby enabling the second test strip taking and placing assembly 71 to move between a position for picking up a test strip from the test strip carousel 60 and a position for installing the test strip into the lower housing.

[0067] As shown in the drawings, Figures 16-18 In one embodiment of the present application, the second test strip taking and placing assembly 71 includes two second clamping jaws 711 that can be opened and closed horizontally, and a pressing member 712 that can be lifted and lowered, the pressing member 712 being arranged between the two second clamping jaws 711, and the lower ends of the second clamping jaws 711 forming clamping portions 7113 for clamping a test strip. The two second clamping jaws 711 each have a sliding shaft 7111 arranged horizontally, and the pressing member 712 has a guide inclined slot 7121 that is in sliding cooperation with the sliding shaft 7111.

[0068] When the two second clamping jaws 711 are moved closer to each other to clamp a test strip, the pressing member 712 will be lifted to a height that does not affect the clamping of the test strip; when the two second clamping jaws 711 are moved away from each other to release the clamped test strip, the pressing portion 7122 of the pressing member 712 presses the test strip downward. In this way, when the test strip is installed into the lower housing, as the two second clamping jaws 711 move away from each other, the pressing portion 7122 of the pressing member 712 presses the test strip downward, so that the test strip can be pressed into the test strip accommodating groove 1011 (see Figure 19 in the lower housing, thereby improving the reliability of the installation of the test strip.

[0069] Further, as shown in the drawings, Figure 18 The two second clamping jaws 711 are arranged to elastically clamp the test strip, and each of the two second clamping jaws 711 is provided with a support shaft 7112, and a torsional spring 713 is sleeved on the support shaft 7112, the torsional spring 713 being used to apply an elastic force to the clamping portion 7113, so as to achieve elastic clamping of the test strip and avoid damage to the test strip.

[0070] As shown in the drawings, Figures 19-20 In another embodiment of the present application, the second test strip taking and placing assembly 71 includes a negative pressure suction head 714, the lower surface of the negative pressure suction head 714 forming a suction surface for suctioning a test strip; opposite sides of the negative pressure suction head 714 are provided with lateral limit members 715, and the lower ends of the two lateral limit members 715 protrude downward beyond the suction surface of the negative pressure suction head 714.
