Problems solved by technology

[0003] 1. The reciprocating motion of the tray is driven by a motor, which consumes a lot of power and is not suitable for applications with low-power portable devices;
[0004] 2. The reciprocating motion of the tray is a uniform motion, and the insertion and withdrawal process is driven by a motor, which takes a long time and low work efficiency
[0005] 3. In order to realize the linear and smooth movement of the pallet, the linear motion mechanism of the prior art often needs to be equipped with parallel slide rails and a design to reduce friction. high cost

Embodiment 1

[0062] like Figure 1 to Figure 11 As shown, a motion mechanism includes a drive assembly and a moving part. The drive assembly includes a base 1, a linear motion motor 2, a motor seat 3, a pressure column 4, a spring leaf 5 and a spring leaf 2 6, and the moving part For the test card 7. The test card 7 can be a chromatography test card or other test cards.

[0063] The base 1 is provided with a linear chute 8 for inserting the detection card 7 , and the detection card 7 is slidably matched with the linear chute 8 . One end of the spring piece 1 is fixed on the base 1, and the other end is a free end extending obliquely to the top surface of the base 1. The motor base 3 is installed on the spring piece 5, and the linear motion motor 2 is fixed on the motor base 3. The motor The front end of the seat 3 extends forward from the pressure plate 9, and the spring piece 15 is in a deformed state to press the pressure plate 9 tightly on the top surface of the base 1. At this time, ...

Embodiment 2

[0076] see Figure 12 to Figure 14 The difference between this embodiment and the first embodiment is that the moving part is a tray 14, and the tray 14 is slidably fitted in the linear chute 8, and a limiting structure is correspondingly provided in the tray 14 and the linear chute 8 (in the figure not shown), prevent the pallet 14 from coming out of the linear chute 8. The top surface of the tray 14 is provided with a placement slot 15 matched with the test card. A thread groove 11 matching the output shaft 10 of the linear motion motor is provided on the top surface of the tray 14 along the axis from the front end surface.

[0077] see Figure 14 , the front end of the tray 14 is provided with a boss 14-1, there are flanges for lifting the pressure column on both sides of the boss 14-1, and there are flanges on both sides of the rear end of the tray 14 that are used to squeeze the spring leaf 2 6 to extend outwards. The protruding portion 14-2. The flange includes a fro...

Embodiment 3

[0082] see Figure 15 to Figure 26 , the difference between this embodiment and the first embodiment is that no spring piece 2 is installed in the linear chute 8, but a spring piece 3 16 is installed at the inner bottom of the linear chute 8, corresponding to both sides of the top of the spring piece 3 16 The pressing column 4 extends forward out of the support piece 16-1. The end of the support piece 16 - 1 extends to the bottom of the pressure column 4 , and the support piece 16 - 1 has a certain amount of elastic deformation, so that its end is in close contact with the pressure column 4 .

[0083] see Figure 26 , the front end of the detection card 7 is provided with a boss 7-1, and there are flanges for lifting the pressure column 4 on both sides of the boss 7-1, and the front end plane 7-2 of the detection card 7 is an extruded spring piece Tri-16 extrusion structure. The flange includes a front inclined surface 7-3, a transition surface 7-5 and a rear inclined surface...

Abstract

The invention discloses a movement mechanism which comprises a base, wherein the base is provided with a linear sliding chute used for being inserted by a moving part, and the moving part is slidably matched with the linear sliding chute; a linear motion motor is fixed on a motor base, the motor base is arranged on the base through an elastic part, the front end part of the motor base is provided with a pressure plate in a forwards extending way, and an output shaft of the linear motion motor is a threaded shaft; and the moving part is correspondingly provided with a thread groove. The movement mechanism disclosed by the invention has the advantages of convenience for operation, high speed and high working efficiency.

Description

technical field [0001] The invention relates to a movement mechanism, which is mainly applied to the movement mechanism of small-scale inspection and detection equipment, and is especially suitable for the requirement of linear movement coordinated by manual and motor drive. Background technique [0002] At present, many devices have linear motion mechanisms. For example, when the chromatography card is detected on the detector, the chromatography detection card is carried by the linear motion mechanism, so that the detection window on the chromatography detection card passes through the detector once from the beginning to the end. , the linear motion mechanism drives the tray through a motor, so that the tray realizes linear reciprocating motion, and the detection card is carried on the tray. The defective that this linear motion mechanism exists is: [0003] 1. The reciprocating motion of the tray is driven by a motor, which consumes a lot of power and is not suitable for...
