Detailed Description
The following describes embodiments of the present utility model in detail with reference to the accompanying drawings, and the embodiments and specific working procedures of the present utility model are given by implementing the present embodiment on the premise of the technical solution of the present utility model, but the protection scope of the present utility model is not limited to the following embodiments.
As shown in fig. 1-4, the sample rack lifting and translating mechanism provided by the utility model is composed of a lifting assembly, a translating assembly and a clamping assembly.
The lifting assembly comprises a supporting vertical plate 1, wherein a lifting mechanism 11, a vertical guide rail 12 and a sample frame lifting table 13 connected with the lifting mechanism are arranged on the supporting vertical plate 1. The lifting mechanism 11 is a synchronous belt, a screw rod or a double guide rod driven by a motor, and after the motor is started, the transmission mechanism operates, so that the sample frame lifting table 13 ascends or descends along with the motor. In this embodiment, the synchronous belt mechanism shown in fig. 2 is adopted, one side of the synchronous belt mechanism is provided with a vertical guide rail 12, and the sample rack lifting table 13 is slidably connected with the synchronous belt mechanism, so that not only can the vertical movement be ensured, but also the lifting and descending actions are smoother. The sample rack lifting table 13 is provided with a mounting position contoured with the sample rack, and a avoidance trigger is arranged at the rear side of the mounting position. The avoidance trigger is a pair of upwardly extending uprights 141, each of which has a roller 142 mounted on top of each upright 141 below the translation assembly. A sensor blocking piece 15 is also mounted on the back side of the sample rack lifting table 13, and when the sensor blocking piece triggers a sensor 16 mounted on the support vertical plate 1, a reset signal is sent out.
The translation assembly comprises a supporting platform 21 which is slidably arranged in a mounting hole formed in the supporting vertical plate 1. A pair of linear bearings 22 are vertically installed on the supporting vertical plate 1 above the installation hole, a pair of guide rods 23 penetrating through the linear bearings 22 in a sliding manner are installed on the top of the supporting platform 1, and an elastic return piece is installed on each guide rod 23. In this embodiment, the elastic return member is a compression spring 24, which is disposed on the guide rod 23 in a penetrating manner, and both ends of the compression spring are respectively in contact with the linear bearing 22 and the mounting plate of the guide rod 23. When the support platform 21 moves backward to perform the avoidance operation, the compression spring 24 deforms, and the accumulated deformation can help the support platform 21 to reset. The avoidance action of the support platform 21 is initiated by virtue of its engagement of the bottom ramp structure 25 with the avoidance trigger. The inclined surface structure 25 at the bottom of the supporting platform 21 is inclined downwards from front to back and is correspondingly arranged above each roller 142. When the sample frame lifting table 13 ascends, the upright rod 141 and the roller 142 ascend along with the upright rod, and after the roller 142 touches the inclined surface structure 25, a backward thrust is generated on the supporting platform 21, so that the supporting platform 21 moves backward to avoid the position, and the sample frame can be lifted in place smoothly. The front of the support platform 21 is also fitted with a sample rack pusher 26. When the support platform 21 is reset, the sample rack pusher 26 pushes the sample rack forward to translate, pushing it away from the test site.
In order to match the translation of the sample rack, clamping assemblies are also mounted on both sides of the sample rack lifting table 13. The clamping assembly comprises support rods 31 arranged on two sides of a sample frame lifting table 13, a first telescopic clamping tongue 32 connected with the top of the sample frame is arranged on one side of the support rod 31, and a second telescopic clamping tongue 33 connected with the bottom of the sample frame is arranged on the other side of the support rod 31. The first telescopic clamping tongue 32 and the second telescopic clamping tongue 33 have the same structure, are connected with the supporting rod 31 through the rotating shaft 34, the plane at the top of the first telescopic clamping tongue can be used as a horizontal supporting table, the bottom of the first telescopic clamping tongue is provided with a limiting block 35, and a reset spring 36 is arranged between the back and the supporting rod 31. When the sample frame rises and touches the first telescopic clamping tongue 32 and the second telescopic clamping tongue 33, the two telescopic clamping tongues turn around the rotating shaft 34 to one side of the supporting rod 31, so that a avoidance position is formed, and the sample frame rises smoothly; when the sample frame passes through the first telescopic clamping tongue 32 and the second telescopic clamping tongue 33, the telescopic clamping tongues return under the action of the return springs 36, and when the sample frame has a descending trend, the telescopic clamping tongues cannot overturn to avoid positions due to the action of the limiting blocks 35, so that clamping and supporting are formed on the sample frame.
When the device works, firstly, a sample rack is placed on a sample rack lifting table 13, and then a lifting mechanism 11 is started to enable the sample rack to ascend; in the process, the roller 142 (i.e. the avoidance trigger) on the sample rack lifting platform 13 is gradually connected with the inclined surface structure 25 at the bottom of the supporting platform 21; along with the lifting of the sample rack, the supporting platform 21 gradually retreats to realize the avoidance of the sample rack; in addition, when the sample rack passes through the first telescopic clamping tongue 32 and the second telescopic clamping tongue 33, the first telescopic clamping tongue and the second telescopic clamping tongue rotate to avoid the position, so that the sample rack ascends smoothly. After the sample rack is lifted in place, detecting; after the detection is finished, the motor of the lifting mechanism 11 is reversed, the sample rack lifting table 13 is lowered, and the sample rack is still left at the detection position under the clamping action of the first telescopic clamping tongue 32 and the second telescopic clamping tongue 33; in the process of lowering the sample rack lifting platform 13, the roller 142 of the avoidance trigger gradually breaks away from the inclined surface structure 25 at the bottom of the supporting platform 21, at this time, the supporting platform 21 resets under the action of the compression spring 24, and the sample rack pushing hand 26 at the front side moves synchronously to push the sample rack away from the detection position.
It should be noted that, in the description of the present utility model, terms such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the device or element to be referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
