Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a syringe filling auxiliary tool for laboratory use. Background Art

[0002] Today's adhesive technology itself has been very advanced, and it is widely used in the fields of electronics, communication and new energy. The ratio, mixing and application of adhesives have a great impact on their bonding performance. Therefore, it is crucial to select the correct cartridge system. Only with the correct application system and bubble-free filling technology can good adhesives give full play to their excellent performance. Considering the existing conditions in the laboratory, how to stably hold the cartridge upright without tilting is an important factor affecting the success of filling.

[0003] Chinese Patent CN202320360177.7 discloses a two-component cartridge placement rack, which relates to the technical field of cartridge brackets. It includes a housing, an opening is provided at the top of the housing, a layered body is provided inside the housing, the layered body is used to divide the top and bottom spaces inside the housing, and a receiving groove for placing the cartridge is provided on the layered body; a first covering part is provided at the top of the layered body inside the housing, and the first covering part is slidably arranged inside the housing. The first covering part corresponds to the receiving groove and is used to cover the opening of the cartridge placed in the receiving groove. The two-component cartridge placement rack described in this utility model can improve the stability of the cartridge during glue filling and can also improve the problem that the glue solution splashes onto other liquid storage tubes during the glue injection process. However, the size of the receiving groove is not limited in this patent. The described placement rack can only achieve the function of cartridge filling. If the depth of the receiving groove is too large, the entire cartridge will be buried in it, making it difficult to observe the height of the filled colloid. If the depth of the receiving groove is too small, the exposed part of the cartridge will be too high, resulting in an unstable and tilted situation during placement. Summary of the Utility Model

The first placement groove, the second placement groove, the third placement groove, the fourth placement groove and the fifth placement groove are used for placing glue cylinders.

[0007] In an embodiment of the present utility model, the first base, the second base, the third base and the fourth base are integrally formed into a cube solid base. The side length of the cube solid base is 12 cm - 13 cm, and the height is 20 cm - 22 cm, which is convenient for placing the cube solid base on an electronic balance for weighing.

[0008] The distance from the bottom ends of the first placement groove, the second placement groove, the third placement groove, the fourth placement groove and the fifth placement groove to the bottom end of the cube solid base is greater than 4 cm. The 4 cm thick solid part will buffer the force brought by the impact and play a protective role for the glue cylinder.

[0009] In an embodiment of the present utility model, the material of the cube base is selected from soft foam plastics or semi-rigid foam plastics. The soft foam plastics include materials such as polystyrene and elastic polyurethane. The soft foam plastics are light in texture and elastic, and can act as a bracket and protect the glue cylinder.

[0010] In an embodiment of the present utility model, the first placement groove and the second placement groove are obliquely arranged on the first base along the 45° direction.

[0011] In an embodiment of the present utility model, the opening diameter range of the first placement groove is 22.2 mm - 24.2 mm, and the opening height range of the first placement groove is 90 mm - 100 mm. The first placement groove is used for placing a 30 cc glue cylinder.

[0012] In an embodiment of the present utility model, the opening diameter range of the second placement groove is 22.2 mm - 24.2 mm, and the opening height range of the second placement groove is 145 mm - 155 mm. The second placement groove is used for placing a 55 cc glue cylinder.

[0013] In an embodiment of the present utility model, the maximum distance between the two ends of the third placement groove is 38 mm - 41 mm, and the opening height range of the third placement groove is 90 mm - 100 mm. The third placement groove is used for placing a 50 ml 1:1 two-component glue cylinder.

[0014] In an embodiment of the present utility model, the third placement groove is composed of two slot holes of equal size. There is a first separation groove between the two slot holes. The width of the first separation groove is 5 mm, and the opening height range of the first separation groove is 90 mm - 100 mm, which is convenient for the positioning of the two-component glue cylinder.

[0015] In an embodiment of the present utility model, the maximum distance between the two ends of the fourth placement groove is 38 mm - 41 mm, the opening height range of the fourth placement groove is 90 mm - 100 mm, and the fourth placement groove is used for placing a 50 ml 1:10 two-component glue cylinder.

[0016] In an embodiment of the present utility model, the maximum distance between the two ends of the fifth placement groove is 38 mm - 41 mm, the opening height range of the fifth placement groove is 92 mm - 102 mm, and the fifth placement groove is used for placing a 50 ml 1:2 two-component glue cylinder.

[0017] In an embodiment of the present utility model, the fifth placement groove is composed of two slot holes with a volume ratio of 2:1. There is a second separation groove between the two slot holes. The width of the second separation groove is 5 mm, and the opening height range of the second separation groove is 92 mm - 102 mm, which is convenient for the positioning of the two-component glue cylinder.

[0018] The principle of the syringe filling auxiliary tooling of the present utility model is as follows:

[0019] The depth of the holes opened in the first placement groove, second placement groove, third placement groove, fourth placement groove and fifth placement groove of the present utility model is about 2 cm lower than the height of the corresponding glue cylinder, that is, about 2 - 3 cm of the glue cylinder is exposed after being placed. One is to ensure the stability of the glue cylinder after being placed, and the other is to better observe the liquid level height during the glue filling process, which is convenient for observation. If the depth is too large, the whole glue cylinder will be buried in it, and it is difficult to observe the height of the filled colloid. If the depth is too small, the exposed part of the glue cylinder will be too high, and it will be inclined and unstable during the placement process.

[0020] In the present utility model, when opening the holes in the third placement groove for placing the 1:1 two-component glue cylinder and the fifth placement groove for placing the 1:2 two-component glue cylinder, a separation groove with the same height and a width of 5 mm is opened at the connection of the two glue cylinders, which is convenient for the positioning of the glue cylinders.

[0021] For the first placement groove, the second placement groove, the third placement groove, the fourth placement groove, and the fifth placement groove of the present utility model, the opening size matches the outer diameter size of the rubber cylinder or is 1 - 3 mm smaller than its outer diameter size, so as to facilitate the better upright and fixation of the rubber cylinder, play a role of a bracket, and facilitate the canning of the colloid. An opening size that is too small means that additional force needs to be applied during the process of placing the rubber cylinder, which may cause damage to the material, etc.; an opening size that is too large will cause the rubber cylinder to be not tightly clamped and will shake after being placed. Generally speaking, 1 - 3 mm smaller is the most suitable opening size.

[0022] For some special colloids during the canning process, they need to impact downward by inertia. Using elastic foam plastic, firstly, it plays a buffering role to protect the rubber cylinder, and secondly, it can discharge the air bubbles inside the colloid. For the entire cube base, the deepest point of the opening is more than 4 cm thick solid part away from the lowest point of the cube base. For some colloids or other fluids with poor fluidity and high viscosity, they will stick to the wall of the rubber cylinder during the filling process. At this time, the entire base needs to be held by hand and impacted with a tabletop or other hard objects to achieve the purpose of filling. And the present utility model will buffer the force brought by the impact through the 4 cm thick solid part provided, playing a protective role for the rubber cylinder.

[0023] Compared with the prior art, the present utility model has the following beneficial effects:

[0024] 1. The syringe filling auxiliary tooling of the present utility model uses soft foam plastic or semi - rigid foam plastic, which is light in texture, has good buffering effect, is convenient to use, and the required materials are cheap in cost;

[0025] 2. The syringe filling auxiliary tooling of the present utility model can simultaneously place single - component and two - component rubber cylinders with different ratios, improving work efficiency;

[0026] 3. The syringe filling auxiliary tooling of the present utility model is applicable to the filling of fluids or colloids that can only be defoamed by inertia, and is convenient to operate;

[0027] 4. The syringe filling auxiliary tooling of the present utility model can weigh while filling, achieving the purpose of quantification. Description of the Drawings
