Description

Technical Field

[0001] The invention relates to the technical field of detection equipment and instruments, in particular to a film penetration detection pretreatment device. Background Art

[0002] Thin film materials are now very common polymer materials, and they can be applied in a wide range of fields and scenarios, such as packaging and protective films. In general, although these polymer film materials have good barrier properties, due to the thin thickness of the film materials themselves, they cannot achieve absolute barrier properties. Under certain conditions, they can still produce a certain degree of permeability. For special applications of thin film materials, especially in some environments with high precision requirements, there are correspondingly higher requirements for the special permeability of thin film materials. Therefore, it is necessary to detect the permeability of thin film materials. The detection operation mode of existing thin film material permeability equipment is generally to detect the permeability dynamic curve of the film to be tested in real time until the permeability dynamic curve tends to be flat, and then calculate the final permeability detection parameter value. An important defect of this integrated permeability detection device is that the time from the start of detection to the dynamic equilibrium of the film material is generally quite long, so the cycle of completing a permeability detection of the film to be tested is long and the efficiency is low; on the other hand, during the permeation treatment of the film to be tested, it is not important to detect the change in its permeability when it has not reached the permeation equilibrium. Generally, the permeability dynamic equilibrium can be reached when the permeation treatment of the film to be tested reaches the predetermined time corresponding to the corresponding material. At this time, the permeability detection of the film material can obtain its final permeability parameter value. There is no technical solution for this type of pretreatment device in the prior art. It can be seen that it is necessary to study and design a film permeability detection pretreatment device, which is specifically used to pretreat the film to be tested, and then perform the permeability detection of the film, so as to improve the permeability detection efficiency of the film material.

DETAILED DESCRIPTION

[0021] Example:

[0022] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] As attached Figure 1-5 As shown, a film permeation detection pretreatment device comprises a body 1, a pretreatment gas circuit system and a modular fixture 2, wherein the pretreatment gas circuit system is arranged in the body 1 for performing permeation pretreatment on the modular fixture 2; the body 1 is provided with a plurality of fixture cavities into which the modular fixture 2 can be placed, and the modular fixture 2 is provided with a film detection cavity 5 for placing a film to be tested; the modular fixture 2 is provided with a detection medium inlet 6, a detection medium outlet 7, a permeate inlet 8 and a permeate outlet 19, and the detection medium inlet 6, the detection medium outlet 7, the permeate inlet 8 and the permeate outlet 19 are all connected to the film detection cavity 5; a membrane cavity sealing groove 9 is provided along the periphery of the film detection cavity 5, and a membrane cavity sealing ring 10 for sealing the film detection cavity 5 is provided in the membrane cavity sealing groove 9. The film permeability detection pretreatment device of the present embodiment is a device specially used for the permeability pretreatment of the film material to be tested. Its principle and advantage are that the film to be tested can be sealed and assembled and fixed in the film detection cavity 5 of the modular fixture 2 to form a whole. A single pretreatment device can simultaneously place multiple modular fixtures 2 to perform permeability pretreatment of the film to be tested. After the film to be tested reaches permeability equilibrium after running for a set period of time, the pretreated modular fixture 2 can be directly transferred as a whole to the film permeability detection device to directly detect the permeability of the film to be tested, which greatly facilitates the user's detection operation. In addition, based on the matching of the film permeability detection pretreatment device of the present invention with different pretreatment gas sources, it is possible to achieve a permeability pretreatment detection method in which one film permeability detection device matches multiple pretreatment devices, multiple film permeability detection devices match a single pretreatment device, or multiple film permeability detection devices match multiple pretreatment devices with the same permeate or different combinations of different permeates, which effectively improves the efficiency and flexibility of the permeability detection of the film to be tested.

[0025] It is easy to understand that the modular fixture 2 of the present invention is not limited to a specific shape and structure. In practical applications, as long as it can be compatible with the fixture cavity of the film permeation detection pretreatment device, it can be connected to the pretreatment gas source through the pretreatment gas path system to achieve permeation pretreatment of the film to be tested placed in the film detection cavity 5 of the modular fixture 2. For example, see the attached Figure 2In the embodiment shown, the modular fixture of this embodiment includes an upper mold component 3 and a lower mold component 4. In actual application, the upper mold component 3 and the lower mold component 4 are assembled to form a film detection cavity 5. That is, in actual application of the modular fixture of this structure, a single modular fixture can only be placed in a film to be tested for permeation pretreatment. When the entire film permeation detection pretreatment device is running at full load, the number of films to be tested pretreated is the same as the number of modular fixtures 2 placed. Based on similar pretreatment principles, see Appendix Figure 5 Another modular fixture 2 structure is shown. In this embodiment, the modular fixture includes an upper mold component 3, a middle mold component 301 and a lower mold component 4. After the upper mold component 3, the middle mold component and the lower mold component 4 are assembled, a first film detection cavity 501 is formed between the upper mold component 3 and the middle mold component, and a second film detection cavity 502 is formed between the middle mold component and the lower mold component 4. In this way, the modular fixture 2 of the structure of this embodiment can be used to place two films to be tested at a time for penetration pretreatment at the same time, which can greatly improve the pretreatment efficiency of the film penetration detection pretreatment device. In practical applications, it is only necessary to set the fixture cavity of the film penetration detection pretreatment device to be compatible with the above two or even more modular fixture 2 structures, so that the modular fixture 2 can be connected to the pretreatment gas source through the pretreatment gas path system after being placed in the fixture cavity. Based on the pretreatment detection principle of the film permeation detection pretreatment device of the present invention, the film permeation detection pretreatment device can even be set as other pretreatment devices, such as those used to detect the sealing of containers or bags, as long as the corresponding modular fixture 2 is configured to be connected to the pretreatment gas source through the pretreatment gas path system after being connected to the fixture cavity.

[0026] As a feasible implementation method, specifically referring to the accompanying drawings, in this embodiment, the fixture chamber is a drawer-type fixture chamber 11, which is arranged on several fixture drawers 12 of the body 1, so that the fixture drawer 12 can be opened by pulling, and the modular fixture 2 with the film to be tested is placed in the fixture drawer 12, and the fixture drawer 12 is closed again to perform the permeation pretreatment of the film to be tested. When the equipment is running, the pretreatment gas circuit system of the equipment is connected to the permeate inlet 8 of the modular fixture 2, and the permeate is input according to the parameter conditions set by the equipment system and a constant pressure is maintained. The permeate will penetrate from one side of the film to be tested to the other side under a certain concentration difference or pressure. After maintaining the established permeation conditions for a certain period of time, the film to be tested will reach permeation equilibrium. Since the modular fixture 2 of the present embodiment is configured to be common to both the film permeability detection pretreatment device and the film permeability detection device, the entire modular fixture 2 can be taken out at any time and transferred to the film permeability detection device for final permeability parameter detection of the film to be tested after the film to be tested is permeated pretreated in the film permeability detection pretreatment device and reaches permeation equilibrium, thereby realizing a detection method in which one film permeability detection device matches multiple pretreatment devices, thereby effectively improving the permeability detection efficiency of the film to be tested.

[0027] In order to facilitate operation and improve the efficiency of pretreatment, the film penetration detection pretreatment device of this embodiment is provided with more than two fixture drawers 12, which are specifically adapted to the size of the body 1 corresponding to the device model, and can reasonably and fully utilize the space of the body 1. For example, referring to an embodiment shown in the accompanying drawings, the film penetration detection pretreatment device is specifically provided with 6 fixture drawers 12, which are arranged in two columns and three rows on the front side of the body 1. It is easy to understand that these fixture drawers 12 can be set to open individually or in a unified manner, and are designed according to the actual application needs of the pretreatment device.

[0028] As a preferred embodiment, referring to the accompanying drawings, the film penetration detection pretreatment device of this embodiment further includes an operation display 13 provided on the body 1, and the operation display 13 is used to operate and display the working state of the film penetration detection pretreatment device, so as to facilitate the operation control and pretreatment parameter display of the working state in each fixture drawer 12, etc., and facilitate the user to operate and intuitively understand the operation of the film penetration detection pretreatment device. In this embodiment, a storage groove 14 is provided on the upper side of the body 1, and the operation display 13 is installed in the storage groove 14 through a hinge shaft. When the equipment needs to be operated, the operation display 13 can be flipped up and opened for convenient operation and viewing. When not needed, the operation display 13 can be covered and stored to save space.

[0029] In a preferred embodiment, see the attached Figure 2 and attached Figure 3 As shown, the modular jig 2 of this embodiment is provided with a plurality of first positioning grooves 15 on its side surface, and correspondingly, a plurality of positioning protrusions 16 are correspondingly provided on the inner side surface of the jig drawer 12. When the jig drawer 12 is opened and the modular jig 2 is placed in, the first positioning grooves 15 are aligned with the positioning protrusions 16 on the jig drawer 12 to achieve the positioning and fixation of the modular jig 2, so that the relative position of the modular jig 2 and the jig drawer 12 is fixed, ensuring that the pretreatment gas path system in the equipment can be accurately connected to the permeate inlet, the detection medium inlet, and the detection medium outlet of the modular jig 2 when the equipment is pretreatment running, avoiding leakage, and ensuring that the film permeation detection pretreatment device can perform permeation pretreatment on the film to be tested according to the set parameters.

[0030] Furthermore, the bottom surface of the modular fixture 2 is provided with a second positioning groove 17, and the bottom surface of the fixture drawer 12 is provided with a corresponding hollow hole 18, and the pretreatment gas path system includes a positioning rod corresponding to the second positioning groove 17. It is feasible, as shown in the accompanying drawings, that the second positioning groove 17 includes a long groove section and an end tapered groove, and the shape of the positioning rod is adapted to the shape of the second positioning groove 17. The modular fixture 2 is further positioned by the mutual positioning and cooperation between the second positioning groove 17 and the positioning rod, so as to ensure the accuracy of the position of the modular fixture 2 and the normal operation of the film penetration detection pretreatment device.

[0031] As an implementation mode, referring to the accompanying drawings, the permeate outlet 19 of the modular fixture 2 of this embodiment is arranged on the front side of the lower mold assembly 4, and the permeate inlet 8, the detection material inlet 6 and the detection material outlet 7 are arranged on the upper side of the upper mold assembly 3. Specifically, as described above, the modular fixture 2 of this embodiment is assembled by the upper mold assembly 3 and the lower mold assembly 4. After assembly, the film to be tested is sealed and fixed in the middle and the film detection cavity 5 is divided into two upper and lower chambers. In this embodiment, the lower side of the film to be tested is used as the permeate side, and the upper side is used as the detection material side. The permeate outlet 19 is specially arranged on the front side of the lower mold assembly 4, and its opening and closing is controlled by the switch valve; the permeate inlet 8, the detection material inlet 6 and the detection material outlet 7 are arranged on the upper side of the upper mold assembly 3, so that each inlet and outlet is conveniently connected with the corresponding chamber of the modular fixture 2 and the pretreatment gas path system of the pretreatment device, so that the equipment can be operated to perform corresponding pretreatment and detection tests.
