[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] The inventors of the present application have discovered that the sealing of bottle caps used for filling strongly acidic liquid reagents has always been a pain point in the industry. With the development of prefabricated tube reagents in recent years, the requirements for the sealing of bottle caps have become increasingly higher. Not only must the test tubes not leak at room temperature, but they must also not leak at high temperatures. For example, the standard for digestion of colorimetric reagent tubes (bottles) is that there must not be any leakage even at 150 degrees for 120 minutes or 165 degrees for 20 minutes. At the same time, the gaskets must not be damaged. However, the current common cap-gasket combination technology has the opportunity for the gasket to come into contact with the highly corrosive liquid or gas in the reagent tube (bottle), resulting in unstable quality of prefabricated tube reagents.

[0043] For example, the current common gaskets are made of a composite material of silicone and polytetrafluoroethylene film. The size of the gasket is made slightly larger than the bottom of the bottle cap, and the gasket is clamped by the threads on the inner wall of the bottle cap to complete the integration of the cap and gasket. The sealing gasket cap designed in this way has a loose cap-gasket combination, and there is always a chance that the silicone gasket will come into contact with the highly corrosive gas or liquid in the reagent tube (reagent bottle). On the one hand, the sealing of the reagent tube (bottle) cannot be guaranteed, and on the other hand, the silicone gasket is easily corroded, resulting in unstable quality of prefabricated tube reagents.

[0044] Based on this, in the embodiment of the present application, the bottom of the bottle cap is surface treated and blow-dried to make it easy to bond with the gasket, so that the bonding effect of the adhesive is better; the gasket and the test tube cap are bonded with an adhesive to form a cap-gasket integration, ensuring that the gasket fits flatly to the bottom of the bottle cap; the gasket is made of suitable material, which can not only meet the anti-corrosion requirements, but also ensure sealing at room temperature and high temperature.

[0045] refer to Figure 1-4 As shown, Figure 1-4 The present invention provides a cap and gasket combination loading machine structure, which includes a main frame 100, a cap sorting mechanism 1, a surface treatment unit 2, a glue dispensing mechanism 4, a gasket sorting mechanism 5, a tablet pressing mechanism 6 and a turntable assembly 7. The glue dispensing mechanism 4, the tablet pressing mechanism 6 and the turntable assembly 7 are installed on the main frame 100. The function of the present invention is to combine the gasket with the bottle cap.

[0046] like Figure 2 , 5 As shown, the cap sorting mechanism 1 includes an outer cap vibration plate 11, a bottle cap conveying trough 12, a bottle cap guide rail 13 and a bottle cap conveyor belt 14. The bottle cap conveyor belt 14 is installed on the main frame 100, the bottle cap guide rail 13 is located above the bottle cap conveyor belt 14, the bottle cap conveying trough 12 is connected to the outer cap vibration plate 11, and it extends to the bottle cap conveyor belt 14, and the surface treatment unit 2 is located above the bottle cap guide rail 13.

[0047] After the bottle caps are sorted in the outer cap vibration plate 11, they enter the bottle cap conveying slot 12, with the bottle cap opening facing upward, so as to facilitate the subsequent processing. The bottle caps can be made of PC or PP. The number of bottle cap conveying slots 12 and bottle cap guide rails 13 is the same, and the number is preferably 2. In this way, two bottle caps can be processed at the same time, that is, a double-head cap and pad combination loading machine is formed.

[0048] like Figure 2 , 6As shown, the turntable assembly 7 includes a rotating disk 71, and a plurality of limiting notches 72 are provided on the rotating disk 71. One end of the bottle cap guide rail 13 is connected to the rotating disk 71; the glue dispensing mechanism 4 includes a glue dispensing tube 41 and a moving unit. The glue dispensing tube 41 is installed on the moving unit, and the glue dispensing tube 41 is arranged above the rotating disk 71. The moving unit includes a horizontal moving cylinder 42 and a vertical moving cylinder 43; in actual use, the glue dispensing mechanism 4 includes a container containing adhesive, which is placed on the rotating disk 71. When glue dispensing is required, the glue dispensing tube 41 is moved to the top of the adhesive container under the action of the horizontal moving cylinder 42, and then, under the action of the vertical moving cylinder 43, it moves downward, and the surface of the glue dispensing tube 41 is coated with adhesive, and then moves downward to the top of the limiting notch 72, and continues to move downward to contact the bottom of the bottle cap at the limiting notch 72 to achieve glue coating, and this reciprocating cycle is repeated.

[0049] like Figure 3 , 7 As shown, the pad arrangement mechanism 5 includes a pad vibration plate 51, a pad conveying groove 52 and a pad guide rail 53 which are connected in sequence. The pad guide rail 53 extends to the sheet pressing mechanism 6. The sheet pressing mechanism 6 includes a vacuum suction pipe 61 and a first lifting cylinder 62. The vacuum suction pipe 61 is driven by the first lifting cylinder 62 to move up and down. The number of the vacuum suction pipe 61 can be 2.

[0050] The function of the sheet pressing mechanism 6 is to absorb the gasket delivered from the gasket arrangement mechanism 5 through the vacuum pipette 61. After absorption, the gasket is located at the bottom of the vacuum pipette 61. When the vacuum pipette 61 moves downward, the gasket is attached to the bottom wall of the bottle cap with adhesive. After that, the vacuum pipette 61 releases the suction force, the gasket is separated from the vacuum pipette 61, and the vacuum pipette 61 moves upward again, and the cycle is repeated.

[0051] In this embodiment, Figure 4 As shown, the cap sorting mechanism 1 also includes a cap sorting bracket 15 and a main roller 18, an auxiliary roller 19 and a first motor 190 installed on the cap sorting bracket 15. The bottle cap conveyor belt 14 is sleeved on the main roller 18 and the auxiliary roller 19. The first motor 190 drives the main roller 18 to rotate; specifically, the first motor 190 transmits power to the main roller 18 through the first gear transmission assembly, and the specific structure of the first gear transmission assembly is not described here. The cap sorting bracket 15 is provided with a first horizontal frame 16 and a second horizontal frame 17, and the bottle cap guide rail 13 is fixedly connected to the first horizontal frame 16.

[0052] In this embodiment, Figure 1As shown, the surface treatment unit 2 includes a nozzle 21 and a peristaltic pump 22, the peristaltic pump 22 is connected to the nozzle 21 through a conduit, and the nozzle 21 is installed on the second horizontal frame 17. In the present application, the peristaltic pump 22 is installed on a pump frame, and the conduit is not shown. In actual application, the nozzle 21 can move up and down to spray the chemical substance (i.e., surface treatment liquid) on the inner wall of the bottle cap for surface treatment. The surface treatment liquid can be a mixed solvent of heptane and hexane, and its purpose is to increase the adhesion between the bottle cap and the adhesive and the gasket.

[0053] In this embodiment, a blowing mechanism 3 is also included, and the blowing mechanism 3 includes a blowing pipe 33, and the blowing pipe 33 is located above the bottle cap guide rail 13, and the blowing pipe 33 is installed on the second cross frame 17. The number of the blowing pipes 33 is preferably 2, and the blowing power of the blowing pipes 33 comes from a blowing pump, and the blowing pump is directly selected from the prior art. The function of the blowing mechanism 3 is to dry the inner surface treatment liquid of the bottle cap so that the bottle cap can be better bonded to the gasket through the adhesive.

[0054] In this embodiment, Figure 4 As shown, the turntable assembly 7 further includes a second motor 73 , which is located at the bottom of the rotating disk 71 . The second motor 73 is connected to the rotating disk 71 through a transmission mechanism to drive the rotating disk 71 to rotate.

[0055] In this embodiment, Figure 3 and 5 As shown, the feeding mechanism 8 is also included, and the feeding mechanism 8 includes a guide plate 81, a telescopic cylinder 82 and a feeding inclined plate 83. The guide plate 81 and the telescopic cylinder 82 are fixedly connected, and the feeding inclined plate 83 is located at the edge of the rotating disk 71. The height of the feeding inclined plate 83 is lower than the rotating disk 71. The function of the feeding mechanism 8 is to discharge the material for standby use or enter the next process after the bottle cap and gasket bonding process is completed.

[0056] In the above embodiment, if Figure 7-8 As shown, the vacuum suction tube 61 of the pressing mechanism 6 is installed below the first lifting cylinder 62, and realizes up and down movement under the action of the first lifting cylinder 62; the first lifting cylinder 62 is fixedly installed on a guard plate 63; a through hole 531 is provided at the end of the gasket guide rail 53, and the vacuum suction tube 61 is located directly above the through hole 531.

[0057] After being sorted by the pad arrangement vibration plate, the gasket enters the gasket conveying groove 52. Both ends of the gasket guide are connected to the gasket conveying groove 52 and the pressing mechanism 6 respectively. When the gasket passes through the pressing mechanism 6, the vacuum suction pipe 61 of the pressing mechanism 6 absorbs the gasket and then fits it with the bottle cap under the action of the first lifting cylinder 62. The fitted bottle cap is pressed to ensure that the gasket fits flatly on the bottom of the bottle cap.

[0058] In another embodiment, a filming mechanism 9 is further included, which is arranged on one side of the turntable assembly 7. The filming mechanism 9 includes a second lifting cylinder 91, a position adjustment plate 92 and a pressure column 93. The position adjustment plate 92 is connected to the second lifting cylinder 91. The pressure column 93 is installed below the position adjustment plate 92 and is located directly above the limiting notch 72 of the rotating disk 71. The filming mechanism 9 is used to further press the bottle cap and the gasket that are attached after passing through the pressing mechanism 6 through the pressure column 93.

[0059] In the above embodiment, the pad arrangement mechanism 5 is further provided with an infrared sensing component and an air blowing component, and the infrared sensing component is arranged at a preceding station of the air blowing component.

[0060] The gasket used in the gasket arrangement mechanism 5 is a composite of polytetrafluoroethylene film and silicone. The size of the gasket is smaller than the bottom size of the bottle cap, or in other words, the diameter of the gasket is smaller than the diameter of the inner wall of the bottle cap. The silicone can cover the polytetrafluoroethylene film on one side or both sides. When the silicone and the polytetrafluoroethylene film are combined, the gasket has a front and back side. When it is fitted with the bottle cap, the side covered with the polytetrafluoroethylene film should face upward to achieve an anti-corrosion effect. In this case, an infrared sensor is needed to identify the front or back side. The principle is: the surface of the gasket covered with the polytetrafluoroethylene film and the surface not covered with the polytetrafluoroethylene film have different roughnesses, so as to distinguish the front and back sides. When the gasket has an orientation that does not meet the requirements, the gasket is removed by the blowing component.

[0061] In the above embodiment, the limiting notch 72 is in the shape of an arc, a square or a triangle.

[0062] The present application provides a cover-pad combination wafer loading machine, such as Fig. 9 As shown, after the bottle caps are sorted by the cap sorting mechanism 1, they follow the movement of the turntable assembly 7 and enter the surface treatment unit 2, the blowing mechanism 3, the dispensing mechanism 4 and the sheet pressing mechanism 6 in sequence, and are fitted with the gaskets that have passed through the gasket sorting mechanism 5 and the sheet pressing mechanism 6 in sequence. The fitted bottle caps can be pressed again by the film shooting mechanism 9 to increase the fit of the gaskets. The fitted bottle caps are integrated caps and gaskets. The gaskets are made of silicone with suitable hardness and polytetrafluoroethylene film with a specific thickness. The appropriate gasket size is controlled to meet the anti-corrosion requirements and ensure sealing at room temperature and high temperature. After the surface treatment, the bottle caps are bonded to the gaskets with an adhesive to form an integrated cap and gasket, which can ensure that the gaskets fit the bottom of the bottle caps evenly, achieve high-quality installation of the gaskets and bottle caps, and avoid the silicone gaskets from contacting with the highly corrosive gases or liquids in the reagent tubes (bottles), so as to achieve stable quality of prefabricated tube trial production.
