Abstract
The utility model discloses an electronic weighing device, which is mainly used to weigh soldering flux used in soldering electronic products. The electronic weighing device is mainly formed by placing an electronic weigher on a cart, wherein a limit device inside which the electronic weigher is fixed is arranged on the cart; and a protective cover is covered on the cart. Compared with the prior art, the electronic weighing device adopts a limit frame and the protective cover of the locating electronic weigher to lower the influence of the outside factors such as air flow rate, wind force of an air conditioner, static electricity and the like to the lowest point due to the fact that weighing precision can be directly influenced by subtle changes of the outside environment, and the precise value of the soldering flux can be tested by a simple weighing operation. The electronic weighing device can be used not only to weigh soldering flux, but also to weigh resin adhesive and coating oil and can achieve the purpose of weighing accurately.
Description
Technical field
The utility model relates to a kind of weighing-appliance, refers in particular to the weighing device of the scaling powder that uses in a kind of weighing electronic product welding process.
Background technology
Scaling powder is one of important element in the electronic product welding process, and control scaling powder amount is the key of whole processing procedure in the production run, and the many and few of scaling powder amount will directly influence the welding effect of product, so we need do strict management and control to this parameter.
The management and control scaling powder at first will accurately be measured the weight of scaling powder under the certain parameter condition, convert by formula again and obtain scaling powder weight in this product welding region, the repeated meter of process is calculated the mean value under each parameter condition again, find parameter to change the rule that the back scaling powder changes, thereby can make detailed scaling powder buret control curve map.
Do you how to guarantee the precision measured? because in measuring process, electronic scales is open in air, and the scaling powder amount is to be unit with the microgram, the delicate variation that is to say external environment all will directly influence the degree of accuracy of measurement, for example, the wind-force of air velocity, air-conditioning, static all can quicken the volatilization of scaling powder, and the speed of scaling powder volatilization is directly reacted the variation of output.How to overcome these external environment factors, we need design promptly rationally convenient and practical again safeguard and formulate rationally strict operating process and reach.
The utility model content
At the deficiencies in the prior art part, the utility model provides a kind of electronic-weighing equipment simple in structure, and it can promote the degree of accuracy of weighing scaling powder.
For achieving the above object, technical solutions of the utility model are:
Electronic-weighing equipment, it mainly is positioned over a go-cart by an electronic scales forms, and described go-cart is provided with the stop means of an electronic scales, and electronic scales is fixed in the stop means, also covers in the go-cart and establishes a protective cover.
The usefulness of technique scheme is:
The utility model electronic-weighing equipment is mainly used in the scaling powder that uses in the weighing electronic product welding process, the delicate variation of considering external environment will directly influence the degree of accuracy of measurement, this electronic-weighing equipment has adopted the limitting casing and the protective cover of localized electron scale, the influence of extraneous factors such as the wind-force of air velocity, air-conditioning, static is dropped to minimum, just can measure the accurate numerical value of scaling powder by simple measuring operation once.
Description of drawings
Fig. 1 is the utility model structural representation one;
Fig. 2 is the utility model structural representation two.
Embodiment
The utility model now is described in conjunction with the accompanying drawings and embodiments.
Electronic-weighing equipment as shown in Figure 1, 2, it mainly is positioned over a go-cart 2 by an electronic scales 1 and forms.Described go-cart 2 table tops are provided with the limitting casing 3 of restriction electronic scales 1 displacement, and electronic scales 2 is fixed in the limitting casing 3.Be the influence of extraneous factors such as the wind-force that prevents air velocity, air-conditioning, static to measuring process, the utility model electronic-weighing equipment is a hinged protective cover 4 in go-cart 2 edges, and this protective cover 4 is covered on the electronic scales 1.Also offer a through hole that supplies electronic scales 1 power lead to place on the described go-cart table top, the utility model electronic scales 1 uses 3M along long line, and is easy to operate, is not subjected to the restriction of distance.This equipment is not only used with scaling powder and is weighed, and also can be used for weighing of resin glue, Coating oil, can reach the measurement purpose accurately.
