[0025] The embodiments of this utility model will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement them after reading this specification. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] This invention provides a streamlined sample intake buffer module compatible with emergency sample administration. Please refer to... Figure 1 , 2 The present invention includes a sample inlet track and an emergency sample inlet unit and a buffer unit respectively disposed on both sides of the sample inlet track.

[0027] The sample loading track includes a sample loading conveyor belt 10 and a sample rack detection sensor 40. The sample loading conveyor belt 10 is a small belt conveyor driven by a motor; the sample rack detection sensor 40 is used to detect whether there are sample racks on the sample loading conveyor belt 10, determining whether the sample loading conveyor belt 10 is occupied. The sample rack detection sensor 40 can be a through-beam photoelectric sensor, with its transmitter and receiver respectively located at both ends of the sample loading conveyor belt 10, and its detection direction as follows: Figure 1 The diagram shows a straight line L connecting the transmitter and receiver, forming an angle with the sample feed conveyor 10 to cover the entire sample feed conveyor 10. In other embodiments, the sample holder detection sensor 40 may also employ other types of proximity sensors.

[0028] The emergency sample loading unit includes an emergency sample loading tray 20 disposed on one side of the sample loading conveyor belt 10, a sample rack detection sensor 40 for detecting whether there is a sample rack on the emergency sample loading tray 20, and a sample rack pusher 50 for pushing the sample rack from the emergency sample loading tray 20 to the sample loading conveyor belt 10. The emergency sample loading tray 20 is used to support the emergency sample rack, and its upper surface is generally flush with the sample loading conveyor belt 10; since the number of emergency sample racks is generally small, the length of the emergency sample loading tray 20 is shorter than that of the sample loading buffer tray 30. The sample rack detection sensor 40 can also be a through-beam photoelectric sensor, with its transmitter and receiver respectively disposed at both ends of the emergency sample loading tray 20, and its detection direction forming an angle with the length direction of the emergency sample loading tray 20 to cover the entire area above the emergency sample loading tray 20. When the emergency sample rack is placed on the emergency sample loading tray 20, it is pushed onto the sample loading conveyor belt 10 by the sample rack pusher 50.

[0029] Specifically, in one embodiment, please refer to Figure 4 The sample rack pusher 50 includes a pusher base 51, a slide rail 52 disposed on the pusher base 51, a U-shaped bracket 53 slidably connected to the slide rail 52, and a drive device 54 for pushing the U-shaped bracket 53 to slide. The drive device 54 may adopt a synchronous belt transmission structure, connecting the U-shaped bracket 53 to the synchronous belt, and driving the U-shaped bracket 53 to slide linearly by the movement of the synchronous belt; the drive device 54 may also adopt other linear modules.

[0030] Both ends of the U-shaped bracket 53 are provided with push handles 55. The middle of the push handle 55 is rotatably connected to the U-shaped bracket 53. One end of the push handle 55 protrudes from the sample injection buffer tray 30 or the emergency sample injection tray 20. The emergency sample injection tray 20 is provided with a straight through groove corresponding to the push handle 55, so that one end of the push handle 55 extends above the emergency sample injection tray 20 and makes physical contact with the sample holder. The other end of the push handle 55 extends towards the push handle base 51, and the U-shaped bracket 53 is provided with a stop 56 to limit the rotation range of the push handle 55. Figure 3 As shown, when the pusher 55 pushes the sample rack to the left under the drive of the drive device 54, the sample rack exerts a force in the opposite direction on the pusher 55, causing the pusher 55 to tend to rotate clockwise. However, the stop 56 prevents the clockwise rotation, allowing the pusher 55 to complete the pushing operation. When the pusher 55 returns to the right and encounters another sample rack, it rotates counterclockwise after being subjected to force, passes through the bottom of the sample rack to the other side of the sample rack, and then resets under its own gravity, causing the pusher 55 to flip over and be placed above the emergency sample tray 20, thus enabling it to continue pushing the other sample rack to the right. Furthermore, the other end of the pusher 55 is also provided with a bolt hole 57, and a counterweight is connected to the bolt hole 57 to strengthen the gravity at the other end of the pusher 55.

[0031] In another embodiment, please refer toFigure 5 The sample holder pusher 50 includes a pusher base 51, a slide rail 52 mounted on the pusher base 51, a U-shaped bracket 53 slidably connected to the slide rail 52, and a drive device 54 for pushing the U-shaped bracket 53 to slide. The drive device 54 also uses a synchronous belt drive structure or other linear module to complete the transmission. Pushers 55 are provided at both ends of the U-shaped bracket 53. The middle part of the pusher 55 is rotatably connected to the U-shaped bracket 53. One end of the pusher 55 extends upward from the side of the emergency sample tray 20 and bends to the top of the emergency sample tray 20. A tension spring 58 is provided between the other end of the pusher 55 and the U-shaped bracket 53. The U-shaped bracket 53 is also provided with a stop 56. Its working principle for pushing the sample holder is the same as... Figure 3 The embodiment shown is similar, but the reset is achieved by the elastic force of spring 58 instead of by its own weight.

[0032] Furthermore, a retraction pusher 60 is provided at the bottom of the emergency sample tray 20 facing the sample conveyor belt 10 to prevent the sample holder on the emergency sample tray 20 from getting too close to the sample conveyor belt 10 and interfering with the detection of the sample holder detection sensor 40 on the sample conveyor belt 10. Specifically, please refer to... Figure 3 The retraction pusher 60 includes a retraction sheet metal bracket 61, a retraction shaft 62 rotatably connected to the retraction sheet metal bracket 61, a retraction hook 63 disposed on the retraction shaft 62, and an electric push rod 64 disposed on the retraction sheet metal bracket 61. The retraction hook 63 is provided with a drive arm 65 corresponding to the electric push rod 64, and the retraction hook 63 is provided with a protrusion 66 extending towards the emergency sample tray 20. The emergency sample tray 20 is provided with a through groove corresponding to the protrusion 66. After the electric push rod 64 extends, it contacts the drive arm 65, thereby pushing the retraction hook 63 to rotate, causing the protrusion 66 to extend out of the through groove and push the sample holder away from the sample delivery conveyor belt 10. The drive arm 65 also acts as a counterweight. After the electric push rod 64 retracts, the protrusion 66 returns to its original position under the action of gravity, returning to the bottom of the emergency sample tray 20.

[0033] Preferably, a roller 67 is rotatably connected to the end of the drive arm 65 to reduce wear during contact between the drive arm 65 and the electric push rod 64. The retracting sheet metal bracket 61 is also equipped with a position sensor 68, and the retracting hook 63 is equipped with a position sensing head 69 to detect whether the protrusion 66 has reset. The position sensor 68 can be a photoelectric sensor.

[0034] The buffer unit includes a sample buffer tray 30 disposed on the other side of the sample delivery conveyor belt 10, a sample rack pusher 50 for pushing the sample rack from the sample buffer tray 30 to the sample delivery conveyor belt 10, and a sample rack detection sensor 40 for detecting whether there is a sample rack on the sample buffer tray 30. The sample buffer tray 30 is used to buffer sample racks that are being delivered normally. The sample rack detection sensor 40 can be a through-beam photoelectric sensor, with its transmitting and receiving ends respectively disposed at both ends of the sample buffer tray 30, and its detection direction forming an angle with the length direction of the sample buffer tray 30. The sample rack pusher 50 can be referenced as follows: Figure 4 or Figure 5 The sample rack pusher shown is further provided with a retraction pusher 60 at the bottom of the sample buffer tray 30 facing the sample conveyor belt 10, to prevent the sample rack on the sample buffer tray 30 from getting too close to the sample conveyor belt 10 and interfering with the detection of the sample rack detection sensor 40 on the sample conveyor belt 10.

[0035] The control unit includes a controller electrically connected to the sample rack detection sensor 40, sample rack pusher 50, and retraction pusher 60. The controller can be a programmable logic controller (PLC). When the sample rack detection sensor 40 in the buffer unit detects the presence of a sample rack on the sample buffer tray 30, the controller commands the sample rack pusher 50 to push the sample racks one by one onto the sample conveyor belt 10 and transport them to the sampling area. During this process, if the sample rack detection sensor 40 in the emergency sample delivery unit detects the presence of an emergency sample rack on the emergency sample delivery tray 20, the controller further determines whether the sample conveyor belt 10 is occupied by the sample rack detection sensor 40 on the sample delivery track. Once the sample conveyor belt 10 is unoccupied, the sample rack pusher of the buffer unit stops sample delivery, and the sample rack pusher of the emergency sample delivery unit is given priority to push the emergency sample racks one by one onto the sample conveyor belt 10 and then transport them to the sampling area. After the emergency sample racks have been delivered, the sample delivery of the buffer unit is restarted.

[0036] The above describes one or more embodiments of this utility model in a relatively specific and detailed manner, but it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
