[0001] The invention relates to the technical field of glue or paste sampling, in particular to a quantitative glue sampling method and device. Background Art

[0002] At present, some pastes and glues are sampled or multi-component glues are mixed by mass ratio using electronic balance weighing method. However, there is no specific scale marking on the syringe, and the extrusion amount cannot be guaranteed, which will cause material waste.

[0003] Therefore, it is necessary to propose a quantitative glue taking method and device to solve the above technical problems existing in the prior art. Summary of the invention

[0004] In order to solve the above technical problems, the present invention proposes a method and device for quantitatively taking glue. The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0006] Step 1: Take a cylinder that matches the inner diameter of the syringe;

[0007] Step 2: Calculate the basic unit column push height according to the glue sampling requirements;

[0008] Step 3: Set limit components on the column with equal spacing according to the height calculated in step 2;

[0009] Step 4: Calculate the column pushing height according to the sampling volume, and set a locking component at the corresponding limit component;

[0010] Step 5: Push the column to drive the syringe piston to move until the locking part and the syringe are in contact, and the calculated quantitative colloid is obtained.

[0011] Furthermore, in the second step:

[0012] The calculation formula for sampling based on the colloid mass is as follows: m = ρV = ρ*πR 2 *h;

[0013] Where m is mass, ρ is density, V is volume, R is inner diameter, and h is basic unit height;

[0014] The height calculation formula according to the different densities of the materials is as follows: hx = h1 / ρx;

[0015] Where hx is the height of glue of other density, ρx is the known density of glue, and h1 is the basic unit height.

[0016] As another improvement of the present invention, a quantitative glue extraction device is proposed, comprising a cylinder adapted to the inner diameter of a syringe, wherein the outer side surface of the cylinder is provided with a plurality of limiting components distributed in a direction parallel to the axis of the cylinder, and further comprising a locking component cooperating with the limiting component, wherein the locking component can control the pushing height of the cylinder by abutting against the syringe when the cylinder is pushed.

[0017] Furthermore, the limiting component is a limiting groove arranged on the circumference of the cylinder.

[0018] Furthermore, the locking component is a limiting wedge that cooperates with the limiting groove.

[0019] The beneficial effects of the present invention are:

[0020] (1) The solution of the present invention can measure the volume or the mass, which is fast and convenient;

[0021] (2) The solution of the present invention does not need to use an electronic balance or a measuring cylinder for multiple measurements, thus avoiding material waste and improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be explained more clearly and completely below in conjunction with the drawings in the embodiments. Of course, the described embodiments are only a part of the present invention but not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative labor are all within the protection scope of the present invention.

[0032] A method for quantitatively taking glue, the method comprising the following steps:

[0033] Step 1: Take a cylinder that matches the inner diameter of the syringe;

[0034] Step 2: Calculate the basic unit column push height according to the glue sampling requirements;

[0035] Step 3: Set limit components on the column with equal spacing according to the height calculated in step 2;

[0036] Step 4: Calculate the column pushing height according to the sampling volume, and set a locking component at the corresponding limit component;

[0037] Step 5: Push the column to drive the syringe piston to move until the locking part and the syringe are in contact, and the calculated quantitative colloid is obtained.

[0038] In the second step:

[0039] The calculation formula for sampling based on the colloid mass is as follows: m = ρV = ρ*πR 2 *h;

[0040] Where m is mass, ρ is density, V is volume, R is inner diameter, and h is basic unit height. There is no scale on the surface of the American syringe packaging, so you need to measure the amount yourself.

[0041] like Figure 1 The following are the different sizes of American syringes; ρ = 1g / cm 3 For example, different volume syringes squeeze out 1g or 1mL, the required height is Figure 2 As shown;

[0042] The height calculation formula according to the different density of the material is as follows: hx = h1 / ρx; the spacing of the limit components is adjusted by the formula, and the specific adjustment is as follows: Figure 3 As shown;

[0043] Where hx is the height of glue of other density, ρx is the known density of glue, and h1 is the basic unit height;

[0044] like Figures 4 to 7 As shown, the column shown in the figure is 1 and the limiting groove is 2.

[0045] The present invention proposes a quantitative glue extraction device, which includes a column adapted to the inner diameter of a syringe, wherein the outer side surface of the column is provided with a plurality of limiting components distributed in a direction parallel to the axis of the column, and also includes a locking component cooperating with the limiting component. When the column is pushed, the locking component can control the pushing height of the column by abutting against the syringe.

[0046] Specifically, the limiting component is a limiting groove arranged on the circumference of the column; in the present invention, the limiting groove passes through the column.

[0047] The locking component is a limiting wedge matched with the limiting groove, and the cross section of the limiting wedge is the same as that of the limiting groove;

[0048] In specific applications, different glue taking devices are manufactured according to the size of the limiting groove, with limiting wedges having a length longer than the outer diameter of the syringe, and are inserted into different limiting grooves according to the amount taken out each time.

[0049] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
