Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] figure 1 An embodiment of the quantitative suction method of the powder bottle of the present invention is shown. In this example, if figure 1 As shown, the dose bottle quantitative suction method comprises the following steps:

[0050] Step S1, weighing to obtain a first weight value W1 of the powder bottle.

[0051] During the quantitative suction of the powder bottle, first weigh to obtain the weight value of the powder bottle. The first weight value W1 is the weight obtained when the powder bottle is placed on an electronic scale after the bottle cap is removed.

[0052] Step S2, in...

Abstract

The invention discloses a powder bottle quantitative suction method and a powder bottle quantitative suction device. The powder bottle quantitative suction method comprises the following steps of weighing to obtain a first weight value W1 of a powder bottle; injecting solution into the powder bottle; weighing to obtain a second weight value W2 of the powder bottle after solution injection; according to the required suction amount L, sucking the solution in the powder bottle, wherein L is equal to (W2-W1)*a%, and a% is a preset value; weighing to obtain a third weight value W3 of the powder bottle after suction; when an error e is controlled within the preset accuracy range, quantitatively sucking, wherein e is shown in the attached figure. The powder bottle quantitative suction method has the advantage that the solution in the powder bottle can be sucked according to the required suction amount, so that the suction frequency is reduced, and the weighing frequency of the powder bottle after suction is also reduced, thereby improving the suction efficiency, and avoiding the pricking damage of a rubber cork.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a quantitative suction method for a powder bottle and a quantitative suction device for a powder bottle. Background technique [0002] In the automatic dispensing process, when the dispensing robot is used to quantitatively suck the solution in the powder bottle, the syringe is held by the manipulator and inserted into the powder bottle, and the dispensing robot controls the syringe to suck the solution in the powder bottle. The weight value of the powder bottle and the weight value of the powder bottle after suction obtain the actual suction amount. [0003] Due to the low controllability of each suction volume of the syringe, frequent suction and frequent weighing are prone to occur when quantitatively suctioning the solution in the powder bottle. However, frequent suction and frequent weighing not only lead to low suction efficiency, but also frequent puncture of the rubber s...
