Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] The overall structure of the drawer-type automatic sample feeding device provided in this embodiment is as follows: Figure 1 and Figure 2 As shown, it includes a power unit and a sample delivery unit.

[0021] The power component includes parallel left and right drive rails 2 and a guide rod assembly mounted on and moving along the drive rails. The guide rod assembly includes a left rail guide rod 3, a right rail guide rod 6, and a connecting rod 8 connecting the left and right rail guide rods. In this embodiment, the structure of the drive rails is as follows: Figure 3 As shown, the device includes a support 21 and a guide rail 22 mounted on the support. A sliding block 24 that moves along the guide rail is provided on the guide rail. Further, the guide rail is a lead screw driven to rotate by a motor 23. The sliding block is threaded onto the lead screw, and the rotation of the lead screw causes the sliding block to move linearly. Preferably, the motor is electrically connected to a controller, which remotely controls the motor's start. The two sliding blocks slide synchronously, and the controller controls the synchronous start of the two motors. Further, the support has a groove 26 parallel to the guide rail. The sliding block 24 has a guide block 25 installed in the groove and able to slide along the groove, ensuring stable movement of the sliding block. Further, the support has front and rear photoelectric limit switches 27. Both photoelectric limit switches are connected to the controller. When the sliding block passes the photoelectric limit switch, an electrical signal is generated and sent to the controller via a wire. The controller controls the start of the two motors, thereby limiting the sliding range of the power component (i.e., the sliding range is located between the two photoelectric limit switches). The left and right slide rail guide rods are fixedly connected to the sliding blocks on the left and right drive slide rails, respectively. The sliding blocks drive the left and right slide rail guide rods to slide back and forth.

[0022] In this embodiment, one end of the connecting rod is fixedly connected to one of the left slide rail guide rod and the right slide rail guide rod, and the other end of the connecting rod is connected to the other of the left slide rail guide rod and the right slide rail guide rod through the coupling 7, so as to ensure that the left slide rail guide rod and the right slide rail guide rod move smoothly.

[0023] The sample delivery component includes a sample drawer 1 and a sample tray 11. The sample drawer is fixedly connected to a connecting rod, thus moving synchronously with the connecting rod. The sample drawer has a groove, into which the sample tray is placed. Specifically, the edges of the groove and the bottom of the sample tray are both chamfered at 45°. Figure 4 As shown, ensure the sample tray is centered within the groove. Preferably, the sample drawer is made of high-strength stainless steel, which is resistant to deformation during processing.

[0024] Specifically, the sample delivery drawer includes a horizontally connected drawer bottom plate and a vertically connected drawer cover plate 4. A groove is located on the drawer bottom plate, and the drawer cover plate is connected to a connecting rod. Specifically, a pressure sensor 5 is installed between the drawer cover plate and the connecting rod, and the pressure sensor is connected to a controller. Further, the connecting rod is composed of two rods connected together. A pressure sensor connector 9 and a drawer connector 10 are respectively fixed at the connection point of the two rods. Both the pressure sensor connector and the drawer connector have mounting grooves. The two ends of the pressure sensor are respectively fixed into the mounting grooves on the pressure sensor connector and the drawer connector, thereby connecting the two rods together. The drawer connector is fixed against the drawer cover plate. If the sample delivery drawer is obstructed due to a sample jamming or other reasons, the pressure monitored by the pressure sensor increases and transmits the monitored pressure to the controller. The controller then stops the motor to prevent damage to components.
