Detailed Description
The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.
Referring to fig. 1-4, a rotary tube dropping mechanism according to an embodiment of the present invention is shown. As shown in fig. 1, the rotary test tube dropping mechanism includes two support carrier vertical plates 101, a multi-channel carrier 102 and a plurality of test tube output assemblies 103, the multi-channel carrier uses a high-precision numerically controlled milling machine to process a conveying guide groove 403 (as shown in fig. 4), the top of the support carrier vertical plate 101 is an inclined guide surface, and the carrier 102 is fixed on the top of the support carrier vertical plate 101 and is parallel to the inclined guide surface. The outlet of the conveying guide slot 403 is located at the lowest drop nozzle 404 of the inclined guide surface, and the outlet of each conveying guide slot 403 is provided with the test tube output assembly 103.
As shown in fig. 2, the test tube output assembly 103 includes a rotating arm 201, a rotating arm stopper 202, a motor 205, and a fixing plate 204 of the motor. The transmission shaft of motor 205 is connected through leading to groove 305 in fig. 3 with rotatory arm 201, and motor 205 is fixed on the fixed plate 204 of motor, and the fixed plate 204 of motor is fixed on supporting carrier pipe frame riser 101, and rotatory arm 201 includes U type groove 301 for hold the U type space of single test tube 405, the opening both sides in U type groove 301 are for being a scarf 302 of taking the acute angle, and the effect is for better cutting into in the test tube gets into U type groove 301.
Specifically, this embodiment rotation type test tube mechanism that drops, as shown in fig. 2, under motor 205 power drive, the swinging arm 201 runs anticlockwise (or runs clockwise) to realize single test tube 405 of single output, wherein, the width of carrying pipe support 102's transport guide slot 403 is greater than test tube 405 body diameter and is less than test tube 405 tube cap diameter, is used for holding the test tube. The guide surface 408 acts as a cap for the test tube 402 to be held in order, and the test tube 405 can slide along the inclined guide surface 408 toward the lower end of the inclined guide surface 408 by gravity.
The specific process operation is as follows, as shown in fig. 3 and fig. 4, a first test tube 409 at the lowest enters a U-shaped groove 301 in a rotating arm 201, because only one test tube 405 can be accommodated in the U-shaped groove 301, a test tube of the same conveying guide 403 behind the first test tube 409 is blocked outside the U-shaped groove 301, when the rotating arm 201 is driven by a motor 205 to rotate, the rotating arm rotates counterclockwise, when the U-shaped groove 301 rotates counterclockwise, the position of the opening of the U-shaped groove 301 changes along with the rotation of the motor 205, when the opening of the U-shaped groove 301 faces a tube dropping opening 404, the first test tube 405 slides downward by gravity, and because the diameter of the tube dropping opening 404 is larger than the maximum diameter of a tube cap 402, the test tube 405 drops. Test tube 405 drops and slides down funnel-shaped test tube guide surface 407 to a specified position.
