Detailed Description

The present invention will be further described with reference to the following examples and the accompanying drawings.

As shown in fig. 3, a bottom push-pull mechanism of a sample rack structurally comprises a support base plate 1, a buffer area a and a sample sending channel B are distributed on the support base plate 1, and the buffer area a and the sample sending channel B are arranged in parallel along the length direction of the support base plate 1. The support base plate 1 is provided with a buffer bracket 2, a transfer bearing platform 3 and an execution assembly 4 which is arranged on the transfer bearing platform 3 in a sliding manner.

As can be seen from fig. 1, the lower portion of the buffer bracket 2 is supported above the buffer area a in a suspended manner by the upright 2 a. The transfer bearing platform 3 is positioned in the sample feeding channel B and is arranged opposite to the buffer bracket 2. Both the relay platform 3 and the buffer carriage 2 may be used for placing the sample rack 5. The executive component 4 includes colludes part 4a, and the front end that colludes part 4a can collude in 5 bottoms of sample frame, along with executive component 4 is reciprocal to slide on transfer plummer 3, can realize sample frame 5 at the transfer between transfer plummer 3 and buffer bracket 2 to the realization is got to buffer A and is put sample frame 5.

In this embodiment, the specific implementation structure of the hooking part 4a dragging the bottom of the sample rack 5 to move is as follows:

referring to fig. 1, the executing assembly 4 further includes a base 4b, an elastic element 4c, a cam 4d, and a motor 4e, wherein the base 4b is slidably assembled in the length direction of the transfer platform 3 through a linear guide rail a, the left end of the hooking member 4a is rotatably mounted on the base 4b, the right end is provided with an upward protruding hook stop portion 4a1, the elastic element 4c is a tension spring and is connected between the left end of the hooking member 4a and the base 4b, the motor 4e is fixed on the base 4b, the cam 4d is mounted on an output shaft of the motor 4e, and the motor 4e can drive the cam 4d to rotate when operating.

As can be seen from fig. 2, the sample rack 5 is provided with a notch 5a, and based on the above implementation structure of the executing component 4, the working process of the hooking component 4a for transferring the sample rack 5 from the buffer bracket 2 to the transfer plummer 3 is as follows: at the beginning, the hook stop part 4a1 of the hooking part 4a is rotated downwards by the pulling force of the elastic element 4c, then the executing component 4 is integrally slid rightwards, the hook stop part 4a1 is positioned below the notch 5a of the sample rack 5, then the motor 4e drives the cam 4d to rotate, the cam 4d forces the hooking part 4a to overcome the resistance of the elastic element 4c to rotate anticlockwise, so that the hook stop part 4a1 enters the notch 5a, and finally the executing component 4 is integrally slid leftwards, so that the sample rack 5 can be transferred from the buffer bracket 2 to the transfer bearing table 3.

By reversing the above procedure, the sample rack 5 can be transferred from the transfer stage 3 to the buffer carriage 2.

Further, referring to fig. 4, a belt transmission device 7 is installed between the actuating assembly 4 and the transfer platform 3, and the belt transmission device 7 can drive the actuating assembly 4 to slide on the transfer platform 3 in a reciprocating manner. The working principle of the belt transmission 7 is a means of the ordinary skill in the art and will not be described in detail here.

As shown in fig. 3, the buffer holders 2 are distributed in an array along the length direction of the buffer area a, and the transfer platform 3 is slidably disposed along the length direction of the sample feeding passage B through the linear moving module 6. So design, linear movement module 6 drives transfer plummer 3 and removes in the length direction who send kind passageway B, can realize getting to each buffer memory bracket 2 and put the sample frame, and buffer memory A has bigger temporary storage capacity.

As shown in fig. 1 again, in order to facilitate the entry and exit of the sample rack 5 into and from the buffer bracket 2, the buffer bracket 2 has an open end near the transfer platform 3, and the open end is provided with a guiding bevel 2b. Further, buffer memory bracket 2 is close to the one end bottom of transfer plummer 3 and establishes bar breach 2c, and bar breach 2c can play the effect of dodging, ensures to collude the part 4a horizontal migration in-process of getting, ends colluding portion 4a1 and can drag out sample frame 5. Furthermore, the lower end of the cam 4d is provided with a roller 4f, and in the process that the cam 4d drives the hooking part 4a to rotate anticlockwise, the roller 4f is supported on the hooking part 4a in a rolling manner, so that the friction force can be reduced, and the movement is smoother.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
