[0001] The utility model relates to the technical field related to material transfer, in particular to a shaping module. Background Art

[0002] The rapid development of molecular biology has brought about many new technologies, one of which is the eight-tube PCR technology. PCR (polymerase chain reaction), as an important molecular biology tool, is widely used in DNA amplification and detection. As a variant of PCR technology, the eight-tube PCR technology provides scientists with a more efficient and accurate DNA amplification and analysis method, which greatly promotes the research in the field of molecular biology.

[0003] The PCR tube (also known as PCR reaction tube or test tube) used in PCR technology adopts medical grade highly transparent polypropylene as raw material. Its smooth surface ensures high efficiency and uniformity between samples, and meets the requirements of accurate and efficient PCR reaction. It is used in genetic testing, disease diagnosis, drug development and other fields.

[0004] This type of special-shaped tube faces many difficulties in transportation on the assembly line due to its bottle diameter-to-height ratio, light weight and non-flat bottom. Moreover, this type of special-shaped tube is generally made of plastic-like materials, which are easy to deform and the bottle mouth positioning is not accurate, which brings many problems to subsequent filling and other links.

[0005] The existing special-shaped pipe conveying system is prone to deformation when conveying special-shaped pipes. Qualified special-shaped pipes are usually multi-tubes, and the openings of each small tube should be flush, such as Figure 1 The eight-tube shown in the figure can easily become Figure 2 and Figure 3 state, which leads to filling errors in the subsequent filling process. Utility Model Content

[0006] The utility model aims to provide a shaping module which can be applied to a special-shaped pipe conveying system to solve the problem that the special-shaped pipe is easily deformed when conveying the special-shaped pipe in the existing special-shaped pipe conveying system.

[0007] In order to solve the above technical problems, the utility model provides a shaping module.

[0008] The shaping module of the utility model comprises a base and at least one constraint assembly arranged on the base, wherein a plurality of positioning holes adapted to the special-shaped tubes are arranged at intervals on the base, and the constraint assembly is used to press the special-shaped tubes into the positioning holes to eliminate deformation of the special-shaped tubes.

[0009] Furthermore, the constraint assembly includes a limiter and a pressure rod, the limiter is fixed on the base, one end of the pressure rod is hinged on the base, and the pressure rod can be inserted into the limiter so that the pressure rod limits the special-shaped tube.

[0010] Furthermore, the limiting member includes a fixing portion and a clamping portion, the fixing portion is fixed on the base, and the clamping portion has a limiting groove for the pressure rod to be clamped into.

[0011] Furthermore, the clamping portion includes a supporting section and a guiding section, the supporting section and the guiding section are at an acute angle to form the limiting groove, and the guiding section is arranged obliquely to guide the pressure rod.

[0012] Furthermore, the support section and the fixing portion form a right angle.

[0013] Furthermore, the constraint assembly also includes a reset member arranged on the base, and the reset member is used to reset the pressure rod.

[0014] Furthermore, the reset element is a reset torsion spring.

[0015] Furthermore, the base is a rectangular block, and the plurality of positioning holes are arranged in sequence and at intervals along the length direction of the base.

[0016] Furthermore, after the pressure rod is inserted into the limiting member, its extension direction is perpendicular to the arrangement direction of the plurality of positioning holes.

[0017] Furthermore, after the pressure rod is inserted into the limiting member, the projection of the pressure rod on the base is located in the gap between two adjacent positioning holes.

[0018] Compared with the prior art, the utility model has at least the following beneficial effects:

[0019] When in use, since the small tubes of the special-shaped tube are pressed into the positioning holes, the deformation of the special-shaped tube is corrected under the pressing action of the constraint component, so that the tube mouths of the small tubes are restored to the same horizontal plane, and the subsequent filling process is smoother and more convenient, and filling errors are less likely to occur, which can greatly improve production efficiency and product quality, and also help to reduce labor costs and improve the level of automation.

[0020] Furthermore, the setting of the reset member can reset the pressure rod.

[0021] Furthermore, the plurality of positioning holes are sequentially spaced apart along the length direction of the base, so that the space of the base can be more reasonably utilized and the volume of the shaping module can be reduced as a whole.

[0022] Furthermore, after the pressure rod is inserted into the limiting member, its extension direction is perpendicular to the arrangement direction of the plurality of positioning holes. This arrangement can reduce the contact area between the pressure rod and the special-shaped tube, thereby avoiding contamination of the special-shaped tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0034] The shaping module of the utility model is used in a special-shaped tube conveying system to solve the problem that the special-shaped tubes are easily deformed when conveying special-shaped tubes in the existing special-shaped tube conveying system. The deformation refers to the bending of the special-shaped tube as a whole, and the pipe openings of each small tube are not on the same horizontal plane, which leads to the problem of easy filling errors in the subsequent filling process.

[0035] The following is attached to the instruction manual Figure 4 and Figure 5 , the shaping module of the utility model is introduced.

[0036] In one embodiment, if Figure 4As shown, the shaping module includes a base 311 and at least one constraint component arranged on the base 311, and a plurality of positioning holes 312 adapted to the special-shaped tube 101 are arranged at intervals on the base 311, and the constraint component is used to press the special-shaped tube 101 into the positioning hole 312 to eliminate the deformation of the special-shaped tube 101.

[0037] Since each small tube of the special-shaped tube 101 is pressed into the positioning hole 312, under the pressing action of the constraint component, the deformation of the special-shaped tube 101 is corrected, so that the tube openings of each small tube are restored to the same horizontal plane, and the subsequent filling process is smoother and more convenient, and filling errors are less likely to occur, which can greatly improve production efficiency and product quality, and also help to reduce labor costs and improve the level of automation.

[0038] Preferably, the number of the positioning holes 312 can be determined according to the number of small tubes in the special-shaped tube 101. For example, if the special-shaped tube 101 is an eight-tube, the number of the positioning holes 312 can be eight; if the special-shaped tube 101 is a six-tube, the number of the positioning holes 312 can be six. Of course, the number of the positioning holes 312 can be greater than the number of small tubes in the special-shaped tube 101.

[0039] The number of the constraint components may be one or more. When the number of tubes in the special-shaped tube 101 is small, a small number of constraint components, such as one or two, may be provided. When the number of tubes in the special-shaped tube 101 is large, the number of constraint components may be appropriately increased. Preferably, in order to more stably constrain the special-shaped tube 101, a plurality of constraint components are arranged at equal intervals.

[0040] In order to better constrain the special-shaped tube 101 , the diameter of the positioning hole 312 is slightly larger than the outer diameter of each small tube in the special-shaped tube 101 .

[0041] In one embodiment, the constraint assembly includes a limit member 315 and a pressure rod 314, the limit member 315 is fixed on the base 311, one end of the pressure rod 314 is hinged on the base 311, and the pressure rod 314 can be inserted into the limit member 315 so that the pressure rod 314 limits the special-shaped tube 101, thereby eliminating the deformation of the special-shaped tube 101.

[0042] Further, in one embodiment, if Figure 5 As shown, the stopper 315 includes a fixing portion 3151 and a clamping portion, and the fixing portion 3151 is fixed to the base 311, for example, the fixing portion 3151 can be fixed to the base 311 by welding. In other embodiments, the fixing portion 3151 can also be fixed to the base 311 by a threaded connector.

[0043] Preferably, the clamping portion has a limiting groove 3154 for the pressure rod 314 to be clamped into. After the pressure rod 314 is pressed into the limiting groove 3154, the special-shaped tube 101 can be pressed, thereby eliminating the deformation of the special-shaped tube 101, so that the tube openings of each small tube are restored to the same horizontal plane, and the subsequent filling process is smoother and more convenient, and filling errors are less likely to occur.

[0044] Specifically, the clamping portion includes a support section 3152 and a guide section 3153, wherein the support section 3152 and the guide section 3153 are at an acute angle to form the limiting groove 3154, and the guide section 3153 is arranged obliquely to guide the pressing rod 314. The clamping portion can be made of a metal sheet with elasticity, and the pressing rod 314 can slide along the inclined outer side surface of the guide section 3153. During the sliding process, the guide section 3153 is squeezed and leans against the support end. When the pressing rod 314 passes over the guide section 3153, the guide section 3153 is reset, and the pressing rod 314 enters the limiting groove 3154 and is constrained.

[0045] Furthermore, in order to occupy the space of the stopper 315, the support section 3152 and the fixing portion 3151 are at a right angle. Of course, in other embodiments, the angle between the support section 3152 and the fixing portion 3151 can also be an obtuse angle.

[0046] Furthermore, the constraint assembly further comprises a reset member disposed on the base 311 , and the reset member is used to reset the pressure rod 314 . Preferably, the reset member is a reset torsion spring 313 .

[0047] When in use, when the pressing rod 314 is pressed, the pressing rod 314 swings toward the direction close to the clamping portion, and the reset torsion spring 313 is elastically deformed. When the pressing rod 314 is removed from the limiting groove 3154 of the clamping portion, the elastic potential energy in the reset torsion spring 313 is released, so that the pressing rod 314 is reset.

[0048] In one embodiment, the base 311 is a rectangular block, and the plurality of positioning holes 312 are arranged in sequence and spaced apart along the length direction of the base 311, so that the space of the base 311 can be more reasonably utilized and the volume of the shaping module can be reduced as a whole.

[0049] In one of the embodiments, after the pressure rod 314 is inserted into the limiting member 315, its extension direction is perpendicular to the arrangement direction of the plurality of positioning holes 312. This arrangement can reduce the contact area between the pressure rod 314 and the special-shaped tube 101, thereby avoiding contamination of the special-shaped tube 101 and ensuring the quality and safety of the special-shaped tube 101.

[0050] Furthermore, after the pressure rod 314 is inserted into the limiting piece 315, the projection of the pressure rod 314 on the base 311 is located in the gap between two adjacent positioning holes 312. When the special-shaped tube 101 is located on the base 311, the pressure rod 314 will be pressed on the connection position between two adjacent small tubes of the special-shaped tube 101, so that the special-shaped tube 101 will not interfere with the subsequent operation process.

[0051] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
