[0027] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figure 1-9As shown, a front-end loading mechanism of a urine protein analyzer includes a cabinet 1. A sample placement table 2 is provided in the cabinet 1. The sample placement table 2 is used for transferring and placing samples to be tested. A grabbing manipulator 3, a horizontal pushing mechanism 4 and a forward mechanism 5 are respectively connected to the sample placement table 2 in the cabinet 1. The grabbing manipulator 3 can freely extend into or out of the cabinet 1 to grab external samples to be tested to the sample placement table 2. The horizontal pushing mechanism 4 is used to push the samples to be tested on the sample placement table 2 to the forward mechanism 5. A feeding hole 11 is provided on the side wall of the cabinet 1. The forward mechanism 5 can pass through the feeding hole 11. The urine protein analyzer is placed on one side of the cabinet 1. After passing through the feeding hole 11, the forward mechanism 5 can transport the samples to be tested to the urine protein analyzer.

[0029] Before testing, the sample to be tested is pre-placed on the side of the cabinet 1. The grabbing manipulator 3 extends out of the cabinet 1 to grab the sample to be tested and place it on the sample placement table 2. The sample is then pushed to the forward mechanism 5 by the horizontal push mechanism 4. The forward mechanism 5 then transports the sample to the urine protein analyzer, completing the automatic feeding process. The front-end feeding mechanism of the urine protein analyzer can realize automatic feeding of the urine protein analyzer through the cooperation of the grabbing manipulator 3, the horizontal push mechanism 4 and the forward mechanism 5, thereby enabling the urine protein analyzer to achieve fully automatic operation without manual supervision, effectively saving human resources and thus improving testing efficiency.

[0030] like Figure 1 As shown, the cabinet 1 is provided with a protective door 12, which is connected to the cabinet 1 in an openable and closable manner. The provision of the protective door 12 can prevent the user's body from extending into the cabinet 1 during inspection, thereby improving safety. On the other hand, it can also facilitate opening the cabinet 1 and inspecting the internal structure of the cabinet 1.

[0031] like Figure 3 As shown, the grabbing robot 3 includes a robot fixing frame 31, which is fixedly connected to the cabinet 1. The robot fixing frame 31 is provided with a grabbing front and rear module 32, and the output end of the grabbing front and rear module 32 is provided with a grabbing left and right module 33, and the output end of the grabbing left and right module 33 is provided with a grabbing lifting module 34, and the output end of the grabbing lifting module 34 is provided with a clamping component 6. The grabbing front and rear modules 32 are used to drive the clamping assembly 6 to move forward and backward, the grabbing left and right modules 33 are used to drive the clamping assembly 6 to move left and right, and the grabbing lifting module 34 is used to drive the clamping assembly 6 to move up and down. The clamping assembly 6 is used to grab or release the sample to be tested; through the cooperation of the grabbing front and rear modules 32, the grabbing left and right modules 33 and the grabbing lifting module 34, the clamping assembly 6 can be driven to extend out of the cabinet 1 to grab the sample to be tested, and the sample can be transported and placed on the sample placement table 2, thereby realizing the function of transferring the sample placed externally to the sample placement table 2, so that the pushing mechanism 4 can push the sample on the sample placement table 2 to the forward mechanism 5.

[0032] In this embodiment, the front and rear grabbing modules 32, the left and right grabbing modules 33, and the grabbing and lifting modules 34 all employ a motor pulley structure. In other embodiments, the front and rear grabbing modules 32, the left and right grabbing modules 33, and the grabbing and lifting modules 34 may also employ a motor screw structure, a pneumatic cylinder structure, an electric cylinder structure, or other structures capable of driving linear motion.

[0033] like Figure 4 As shown, the clamping assembly 6 includes a clamping fixing plate 61, which is connected to the output end of the grabbing and lifting module 34. The clamping fixing plate 61 is provided with a clamping motor 62, a first clamping plate 63 and a clamping guide rail 64. The output end of the clamping motor 62 is provided with a clamping screw 65, and the clamping screw 65 is sleeved with a second clamping plate 66. The second clamping plate 66 is slidably connected to the clamping screw 65, and the second clamping plate 66 is slidably engaged with the clamping guide rail 64. The clamping motor 62 can drive the second clamping plate 66 to move closer to or away from the first clamping plate 63. When it is necessary to clamp a sample, the clamping motor 62 drives the clamping screw 65 to rotate, driving the second clamping plate 66 to slide, causing the second clamping plate 66 to move closer to the first clamping plate 63, thereby bringing the two clamping plates closer to each other and achieving the function of clamping the sample to be tested. When it is necessary to release the grasped sample, the clamping motor 62 drives the clamping screw 65 to rotate in the opposite direction, driving the second clamping plate 66 to slide, causing the second clamping plate 66 to move away from the first clamping plate 63, thereby separating the two clamping plates and achieving the function of releasing the sample to be tested. By providing a clamping guide rail 64 on the clamping fixed plate 61, the running direction of the second clamping plate 66 can be limited and guided, thereby improving the stability of the transmission.

[0034] like Figure 5 、 6 As shown, the horizontal pushing mechanism 4 includes a horizontal pushing mounting frame 41, which is connected to the cabinet 1. The horizontal pushing mounting frame 41 is equipped with a horizontal pushing motor 42 and a horizontal pushing driven wheel 43. The output end of the horizontal pushing motor 42 is equipped with a horizontal pushing driving wheel 44. The horizontal pushing driving wheel 44 and the horizontal pushing driven wheel 43 are sleeved with a horizontal pushing transmission belt 45. The horizontal pushing transmission belt 45 is equipped with a horizontal pushing slider 46, and the horizontal pushing slider 46 is equipped with a push block 47. During operation, the horizontal pushing motor 42 drives the horizontal pushing driving wheel 44 to rotate, thereby driving the horizontal pushing transmission belt 45 to move the horizontal pushing slider 46, causing the push block 47 to move together. During the movement, the push block 47 pushes the sample on the sample placement table 2 toward the advancing mechanism 5 until the sample is pushed onto the advancing mechanism 5. The horizontal pushing motor 42 then reverses, driving the push block 47 to reset, facilitating the pushing of the next sample.

[0035] Specifically, the sample placement table 2 is fixedly mounted within the cabinet 1 via four support columns 21. Two parallel guide slots 22 are provided on the sample placement table 2. The number of push blocks 47 is the same as the number of guide slots 22, and their positions correspond one to one. One end of each push block 47 passes through the corresponding guide slot 22 and is able to slide within the corresponding guide slot 22. During operation, the gripping robot 3 places the sample to be tested on the sample placement table 2. Then, by controlling the horizontal push motor 42 to operate, the push block 47 is driven to slide within the guide slot 22. The push block 47 contacts the sample and pushes the sample on the sample placement table 2 toward the advancing mechanism 5 until the sample is pushed onto the advancing mechanism 5, completing the transfer and transportation process of the corresponding sample.

[0036] To limit and guide the transport direction of the push block 47, a push guide rail 48 is provided on the push mounting frame 41, and the push slider 46 is slidably engaged with the push guide rail 48. When the push motor 42 is in operation, the push slider 46 slides on the push guide rail 48. The cooperation between the push guide rail 48 and the push slider 46 can limit the movement direction of the slider, thereby allowing the push block 47 to slide in the direction of the guide slot 22, thereby improving the stability of the operation.

[0037] like Figure 7 、 8 As shown, the forward mechanism 5 includes a forward fixing plate 51, which is fixedly connected to the cabinet 1. A forward motor 52 and a transmission assembly are mounted on the forward fixing plate 51. The output end of the forward motor 52 is connected to the transmission assembly, and the forward motor 52 can drive the transmission assembly to move. A tray 53 is provided on the transmission assembly. The forward motor 52 can drive the tray 53 to be flush with the sample placement table 2, thereby facilitating the push block 47 to push the sample to be tested onto the tray 53. The forward motor 52 can also drive the tray 53 to move up and down and forward and backward, thereby facilitating the delivery of the sample to be tested to the urine protein analyzer via the tray 53, thereby achieving an automatic feeding process for the urine protein analyzer.

[0038] Specifically, the transmission assembly includes a forward driven wheel 54, which is rotatably connected to the forward fixed plate 51. A forward driving wheel 55 is provided at the output end of the forward motor 52. A forward transmission belt 56 is sleeved between the forward driving wheel 55 and the forward driven wheel 54. A rotating swing plate 57 is provided on the forward driven wheel 54. During operation, the forward motor 52 drives the forward driving wheel 55 to rotate, thereby driving the forward driven wheel 54 to rotate synchronously via the forward transmission belt 56, and in turn driving the rotating swing plate 57 to rotate and swing. The rotating swing plate 57 has a waist-shaped hole 571, a transmission rod 58 is provided on the tray 53, and a 7-shaped guide hole 511 is provided on the forward fixed plate 51. The transmission rod 58 passes through the 7-shaped guide hole 511 and then extends into the waist-shaped hole 571, and can slide in both the 7-shaped guide hole 511 and the waist-shaped hole 571. During the rotation and swinging process of the rotating swing plate 57, the rotating swing plate 57 will push the transmission rod 58 to slide in the waist-shaped hole 571 and the 7-shaped guide hole 511, and be limited by the 7-shaped guide hole 511, thereby driving the tray 53 and the sample to be tested to rise and fall and move back and forth.

[0039] In the present invention, only one drive motor is needed to simultaneously drive the tray 53 to move up and down and in two directions forward and backward, which not only reduces the manufacturing cost of the equipment, but also reduces the size of the equipment, facilitates the placement of the equipment, and improves versatility.

[0040] To limit and guide the direction of movement of the push tray, a forward guide rail 59 is provided on the forward fixed plate 51. A front and rear slider 510 slides on the forward guide rail 59. A lifting guide rail 512 slides on the front and rear slider 510. A lifting slider 513 slides on the lifting guide rail 512. The lifting slider 513 is connected to the tray 53. When the forward motor 52 drives the rotating swing plate 57, the rotating swing plate 57 first pushes the transmission rod 58 to move upward and downward, thereby causing the tray 53 to move upward and downward, driving the lifting slider 513 to slide on the lifting guide rail 512. The cooperation between the lifting slider 513 and the lifting guide rail 512 limits and guides the direction of the tray 53's upward and downward movement. As the rotating swing plate 57 continues to rotate, when the transmission rod 58 passes the corner position of the 7-shaped guide hole 511, the transmission rod 58 is limited by the 7-shaped guide hole 511 and can only move forward and backward. At this time, it drives the tray 53 to move forward and backward, and drives the lifting slider 513, the lifting guide rail 512 and the front and rear sliders 510 to move forward and backward together; through the cooperation of the front and rear sliders 510 and the front and rear guide rails, the direction of the front and rear movement of the tray 53 can be limited and guided, thereby improving the stability of the transmission.

[0041] like Figure 2 、 9 As shown, the advancing mechanism 5 further includes a pushing mechanism 7, which is used to send the sample to be tested on the tray 53 out of the cabinet 1, so as to transport it to the urine protein analyzer.

[0042] Specifically, the pushing mechanism 7 includes a pushing motor 71 and a pushing driven wheel 72, each of which is connected to the cabinet 11. A pushing driving wheel 73 is provided at the output end of the pushing motor 71. A pushing transmission belt 74 is sleeved on the pushing driving wheel 73 and the pushing driven wheel 72. A pushing slider 75 is provided on the pushing transmission belt 74. A pushing plate 76 is provided on the pushing slider 75. The pushing plate 76 can engage with the sample to be tested on the tray 53. During operation, when the advance motor 52 drives the tray 53 and the sample to be tested to translate to the extreme position within the 7-shaped guide hole 511, the pushing driving wheel 73 is driven by the pushing motor 71 to rotate, driving the pushing transmission belt 74 and the pushing slider 75 to move, thereby driving the pushing plate 76 to translate. During the translation process, the pushing plate 76 will engage with the sample to be tested on the tray 53 and push the sample to be tested to slide horizontally until the sample to be tested is sent out of the feeding hole 11 and transported to the urine protein analyzer on one side of the cabinet 1.

[0043] In order to limit and guide the running direction of the push plate 76, a push guide rod 77 is provided at a position corresponding to the push slider 75 on the cabinet 1, and the push slider 75 is slidably connected to the push guide rod 77; when the push motor 71 is working, the push slider 75 slides on the push guide rod 77, and the movement of the push plate 76 is limited and guided by the cooperation of the push guide rod 77 and the push slider, thereby improving the stability of the transmission.

[0044] Working principle:

[0045] Before testing, the sample to be tested is placed on one side of the cabinet 1 in advance. When testing is required, the front and rear grabbing modules 32, the left and right grabbing modules 33 and the grabbing lifting modules 34 are first controlled to work respectively, driving the clamping assembly 6 to extend out of the cabinet 1 and move to the corresponding position of the sample to be tested; then the clamping motor 62 is controlled to work, driving the second clamping plate 66 to move in the direction close to the first clamping plate 63, so that the two clamping plates grab the sample to be tested; then the front and rear grabbing modules 32, the left and right grabbing modules 33 and the grabbing lifting modules 34 are controlled to work respectively, driving the clamping assembly 6 to retract into the cabinet 1 and move to the corresponding position of the sample placement table 2; then the clamping motor 62 is controlled to work, driving the second clamping plate 66 to move in the direction away from the first clamping plate 63, so that the two clamping plates release the sample to be tested and place the sample to be tested on the sample placement table 2; then the front and rear grabbing modules 32, the left and right grabbing modules 33 and the grabbing lifting modules 34 are controlled to work, driving the clamping assembly 6 to return to its initial position.

[0046] Then, the horizontal push motor 42 is controlled to work, driving the push block 47 to slide in the guide groove 22, so that the push block 47 pushes the sample to be tested on the sample placement table 2 to move toward the advancing mechanism 5 until the push block 47 pushes the sample to be tested onto the tray 53; then, the horizontal push motor 42 is controlled to reverse and drive the push block 47 to return to its initial position.

[0047] Then the forward motor 52 is controlled to work, driving the rotating swing plate 57 to rotate and swing; during the rotation of the rotating swing plate 57, the rotating swing plate 57 will first push the transmission rod 58 to rise, so that the push plate with the sample to be tested will rise; as the rotating swing plate 57 continues to rotate, when the transmission rod 58 passes the corner position of the 7-shaped guide hole 511, the transmission rod 58 is limited by the 7-shaped guide hole 511 and can only move forward and backward, at this time driving the tray 53 and the sample to be tested to move forward; when it moves to the limit position, the pushing motor 71 is controlled to work, driving the push plate 76 to translate, and the push plate 76 will push the sample to be tested on the tray 53 through the feeding hole 11, thereby outputting the sample to be tested to the urine protein analyzer on one side of the cabinet 1, realizing the process of automatically feeding the urine protein analyzer.

[0048] The above-mentioned specific implementation manner is a preferred implementation manner of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation manner. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
