Technical Field

The present invention relates to a multiple sample loading system.

Background

In many industrial fields, a sample to be measured is often required to be sent to a specified point to be measured for detection, single measurement is gradually changed into multiple measurements, and the process from manual measurement to semi-automatic measurement to full-automatic measurement is gradually changed.

The working principle of the existing sample loading system is as follows: the sample exchanger places the desired sample 1 on the loading elevator 2. The loading elevator 2 brings the sample cartridge or sample 1 into the sample holder 3, the loading elevator 2 is further lowered, the conveyor removes the sample holder 3 and the sample cartridge from the sample chamber 4, the sample cartridge or sample 1 is moved into the spectroscopic cell, and the sample cartridge or sample 1 is ejected into the analysis position.

Referring to fig. 1, fig. 1 is a simplified schematic diagram of a conventional sample loading system. As shown in fig. 1, the sample loading system of the prior art requires a plurality of motors to ensure the object to be measured reaches the measurement position, such as: a conveyor motor 5, a loading lift motor 6, a sample room gate motor 7, a spectrographic room lift lever motor 8, a sample rotation motor, and the like. Therefore, the object to be measured needs to move for many times to reach the point to be measured, and the existing transfer piece (the sample frame 3) has no specific positioning part, so that the in-place precision of the sample cannot be ensured, and the more the transfer times are, the more the offset is easy to occur. When the sample reaches the spectrum chamber, mechanisms such as a sample rotating motor and the like are needed to be matched to adjust the position of the sample, and the action of position debugging is carried out for multiple times.

Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.

The multiple sample loading system of the present application is fixed to the mounting deck 9. The multiple sample loading system includes a carousel 10, a transport mechanism 11, and a jacking mechanism 12. The detailed structure is shown in fig. 2 to fig. 4.

The carousel 10 of the present application may be adjacent to the sample chamber or directly in place within the sample chamber. The turntable 10 is mainly used for smoothly conveying the sample bottles a out of the sample chamber and transferring the sample bottles a to the conveying mechanism 11. The rotary table 10 is fixed on the fixed base 102 through four height adjusting bolts 101, and is locked by a fixing nut after being adjusted to a proper height. The rotary table 10 is arranged on the mounting table 9 through a fixing seat 102, and is connected with a driving motor 103 through a rotating shaft, and the rotary table 10 is rotated through the driving motor 103. As shown in fig. 3, the turntable 10 is provided with a plurality of sample wells 104 that are open toward its edge. The rotary disc 10 rotates half a turn from the sample chamber to reach a sampling position B, and is right opposite to the conveying mechanism 11 and the jacking mechanism 12.

As shown in fig. 3 and 4, the conveying mechanism 11 of the present application includes a conveying wheel 111, a conveying belt 112, a guide rail 113, and a tray 114. The two conveying wheels 111 cooperate with the conveying belt 112 to form a main conveying structure. The conveying wheel 111 is respectively arranged at the fixed seat 14 and the jacking mechanism 12, the conveying belt 112 is sleeved on the conveying wheel 111, and the conveying wheel 111 is driven by a horizontal motor 15. The guide rail 113 is laid below the turntable 10 to the jacking mechanism. The tray 114 is fixed on the guide rail 113 by a bracket 115 and a slider. The tray 114 moves along the guide rail 113 by the driving of the conveyor belt 112. The conveying of this application is linear orbit, has reduced the risk that many times turning of transportation process leads to the skew relative prior art.

Referring to FIG. 5, a close-up view of a portion of the tray 114 of the present application is shown. The tray 114 is an annular body with an opening facing the jacking mechanism 12, and the tray 114 is concentric with the sample cup a, so that the problem of offset of the tray 114 when the sample cup a is received is avoided, and the precision in the transportation process is ensured. A liftable guide column 117 is arranged in the annular body of the tray 114, a limiting column 116 with a convex surface is arranged on the annular body, and the guide column 117 and the limiting column 116 are distributed at two opposite ends of the opening. The height of the limiting column 116 is flush with the upper surface of the rotary disk 10, and when the tray 114 moves to the sampling position B, the limiting column 116 is located at the opening of the sample slot 104. The limiting columns 116 are mainly used for accurately limiting and stably receiving the sample cup a in the sample tank 104. The liftable guiding column 117 gradually moves downwards when the tray 114 moves to the sampling position B, and gradually moves upwards when the tray 114 removes the sampling position B until the height of the liftable guiding column is consistent with that of the limiting column 116. During transportation, the limiting column 116 and the lifting guide column 117 limit the sample cup a therebetween, so that the sample cup a is ensured not to shake during movement and is in a concentric state with the tray 114.

In addition, spring balancing devices are uniformly distributed between the annular body and the support, each spring balancing device is a guide post and a spring sleeved on the guide post, the guide post penetrates through the annular body, and the springs are clamped between the annular body and the support. The spring balancing devices are uniformly distributed, share stress and can increase relative stability in the transportation process.

Referring again to fig. 2, 3 and 4, the jacking mechanism 12 of the present application is fixed on the mounting platform 9. The jacking mechanism is used for jacking the sample cup A to reach a measuring point in the spectrum chamber. As shown in the figure, the jacking mechanism 12 of the present application includes a screw rod 122 with a screw rod motor 121 connected to the bottom, a cup holder 123 is fixedly connected to the top end of the screw rod, and the cup holder 123 is lifted under the pushing of the screw rod 122. Referring to fig. 6, the bottom of the cup holder 123 is provided with an annular clamping groove 1231, and the bottom of the sample cup a is provided with a raised clamping ring, so that the annular clamping groove and the sample cup are matched with each other, and accurate positioning can be ensured.
