Referring to fig. 1 and fig. 2, a method for detecting a degree of balance of a pressure maintaining device according to an embodiment of the present invention includes the following steps:
pre-attaching the adhesive tape 10 to the surface of the article 20 to be pressure-maintained and placing the article 20 to be pressure-maintained on a pressure-maintaining device;
and (3) applying pressure maintaining equipment on the adhesive tape 10 and maintaining the pressure of the object 20 to be maintained, so that the adhesive tape 10 and the object 20 to be maintained have different surface fitting tightness and present different states, and judging the balance degree between the pressure maintaining equipment and the object 20 to be maintained according to the state presented by the adhesive tape.
Referring to fig. 1, specifically, the adhesive tape 10 is pre-attached to the surface of the object 20 to be pressure-maintained, the object 20 to be pressure-maintained and the attached adhesive tape 10 are placed in a pressure-maintaining device (or the object 20 to be pressure-maintained is placed in the pressure-maintaining device first, and then the adhesive tape 10 is pre-attached, and certainly, the adhesive tape 10 may also be attached to the pressure-maintaining device), and after applying a certain pressure to the object to be pressure-maintained, the adhesive tape 10 will present different states according to the degree of balance of the pressure-maintaining device, and an operator can determine the degree of balance between the pressure-maintaining device and the object 20 to be pressure-maintained according to the state of the adhesive tape 10, thereby calibrating the pressure-maintaining device. Compared with the prior art, the balance degree condition of the pressure maintaining equipment is judged by adopting a large amount of pressure-maintained products, or the balance degree condition of the pressure maintaining equipment is judged by matching white paper and carbon paper, the detection method adopted by the embodiment can be realized by only one layer of adhesive paper 10, the adhesive paper 10 is provided with back adhesive, when the adhesive paper is attached to the surface of the object 20 to be subjected to pressure maintaining, other tools or devices are not needed, the adhesive paper 10 can be adhered to the surface of the object 20 to be subjected to pressure maintaining, and compared with the white paper and the carbon paper in the prior art, the detection method is simpler and more convenient to use, and has better reliability.
In addition, for some pressure maintaining equipment under the conditions of low temperature and low pressure, the detection method of the copy paper and the white paper in the prior art cannot effectively detect the balance degree of the pressure maintaining equipment under the conditions of low temperature and low pressure due to the characteristics of the detection method, but the detection method adopting the adhesive paper 10 provided by the embodiment has better adaptability to temperature and pressure, can effectively detect under the conditions of low temperature and low pressure, and effectively overcomes the limitations of the copy paper and the white paper.
With reference to fig. 1 and fig. 2, as an alternative implementation manner of this embodiment, the adhesive paper 10 may be a common adhesive paper, the adhesive paper 10 is attached to the surface of the object 20 to be held, and the adhesive paper 10 may be in a dark color state and a light color state, where the dark color state indicates that the adhesive tightness between the adhesive paper 10 and the surface of the object 20 to be held is high, and the light color state indicates that the adhesive tightness between the adhesive paper 10 and the surface of the object 20 to be held is not tight. Specifically, if the gummed paper 10 has the light color part 101, the distance between the pressure holding device and the article to be pressure-held 20 at the position of the light color part 101 is adjusted to be reduced, so that the pressure holding device can sufficiently hold pressure on the article to be pressure-held 20. It should be noted that the light color part 101 and the dark color part 102 in this embodiment both refer to the color of the adhesive paper 10 appearing on the surface of the article 20 to be held, and the color of the adhesive paper 10 on the area is always unique for the vacancy 201, such as a through hole, an opening, etc., on the surface of the article 20 to be held, and this embodiment will not be described in detail.
Further, as one optional implementation manner of this embodiment, the original adhesive paper 10 is torn off, and the adhesive paper 10 with the same thickness is used for pressure maintaining again. In the concrete application, after the object 20 to be subjected to pressure maintaining is subjected to pressure maintaining, the light color part 101 presented on the surface of the adhesive tape 10 indicates that a gap exists between the pressure maintaining device and the surface of the object 20 to be subjected to pressure maintaining, the gap between the corresponding position of the pressure maintaining device and the object 20 to be subjected to pressure maintaining can be adjusted, and then the gap between the corresponding position of the pressure maintaining device and the object 20 to be subjected to pressure maintaining is reduced, and the detection is carried out again until the light color part 101 does not appear on the surface of the object 20 to be subjected to pressure maintaining on the adhesive tape 10.
Preferably, the adhesive paper 10 may be an elastic adhesive paper. In the concrete application, the elastic adhesive tape has certain elasticity (or compressibility), after the pressure maintaining operation, if the adhesive tape 10 has the light color part 101 on the surface of the object 20 to be maintained, it indicates that the distance between the position of the pressure maintaining device corresponding to the light color part 101 and the object 20 to be maintained is greater than the thickness of the adhesive tape 10, and the adhesive tape 10 with the appropriate thickness can be reasonably selected according to different size structures of the product to be maintained, and the embodiment is not limited. Therefore, the gap between the pressure maintaining equipment and the surface of the object to be maintained 20 can be determined by using the adhesive tapes 10 with different thicknesses or laminated sheets, the equipment can be further accurately calibrated, and the product yield is improved.
Referring to fig. 2, specifically, as an optional implementation manner of this embodiment, if the adhesive tapes 10 are all dark color portions 102, the original adhesive tape 10 can be torn off from the surface of the object 20 to be pressure-maintained, the adhesive tapes 10 with different thicknesses are attached to the surface of the object 20 to be pressure-maintained, and then the object is placed in the pressure-maintaining equipment again for pressure maintaining. Specifically, after pressure maintaining, the gap between the dark color part 102 on the surface of the adhesive tape 10 and the article 20 to be maintained at the corresponding position of the pressure maintaining device is smaller than the thickness of the adhesive tape 10, otherwise, it indicates that the gap between the article 20 to be maintained at the corresponding position of the pressure maintaining device is larger than the thickness of the adhesive tape 10. In the specific application, if the gummed paper 10 after pressure maintaining is the dark color part 102, the gummed paper 10 can be torn off, the gummed paper 10 with the thinner thickness is selected to be attached to the surface of the object 20 to be subjected to pressure maintaining, the pressure maintaining operation is performed again, the color of the gummed paper 10 after pressure maintaining is observed again, and if the light color part 101 appears, the pressure maintaining equipment is correspondingly adjusted to reduce the distance between the parts. So, can adjust the pressurize equipment according to the part of different colours on the adhesive tape 10 to detect repeatedly, thereby reach the purpose of accurate regulation pressurize equipment.
Referring to fig. 1, as an alternative embodiment of the present embodiment, the detection method further includes cutting the adhesive tape 10 into a shape that is the same as the contour of the surface of the article 20 to be held. In this way, the adhesive tape 10 can completely cover the surface of the article 20 to be subjected to pressure maintaining, so as to determine whether the distance between the positions of the pressure maintaining device is accurate, and of course, the size of the adhesive tape 10 can be larger than the surface of the article 20 to be subjected to pressure maintaining, and only the adhesive tape 10 can completely cover the positions of the surface of the article 20 to be subjected to pressure maintaining. In the concrete application, can cut into the unit module of standard size with the adhesive tape 10, to the great article 20 that waits to pressurize of size, can be with the continuous laminating of many adhesive tapes 10 of standard size on waiting to pressurize the article 20, improve application scope.
Preferably, the adhesive paper 10 may be a blue transparent adhesive paper 10. In a specific application, the color of the adhesive tape 10 can be selected according to the color of the article 20 to be maintained, and only the adhesive tape 10 can present a dark color part 102 and a light color part 101 on the surface thereof, which is not limited in this embodiment.
As an alternative embodiment of the present embodiment, the adhesive paper 10 may be a pressure color-changing adhesive paper, and the pressure color-changing adhesive paper may exhibit different colors according to different pressures. Specifically, the pressure-chromic adhesive paper may include an adhesive layer for conforming to the surface of the article 20 to be pressurized, and a color-changing layer that may be coated with a pressure-chromic indicator that may include a color-forming reactant pair including a color activator, also referred to as a developer, and a color precursor. Typically, the color-changing layer is colorless until associated and/or reacted with a color-activating agent, such that the color-changing layer may exhibit a different color depending on the pressure to which it is subjected, e.g., colorless, transparent or white when unstressed, blue or red when stressed, and darker colors when stressed with greater pressure. Therefore, after the pressure is maintained on the object 20 to be maintained, the color presented by the pressure color-changing gummed paper is different, so as to judge the balance degree condition of the pressure maintaining equipment, specifically, for the position where the color is not changed or the color is lighter, the distance between the pressure maintaining equipment and the object 20 to be maintained can be reduced, and for the color distortion depth, the pressure at the position is too large, so that the distance can be adaptively adjusted.
Further, the pressure gummed paper that discolours can also include the isolation layer, and the discoloration layer is located between bonding layer and the isolation layer, avoids the discoloration layer because of the pressurized adhesion on pressurize equipment or treat pressurize article 20.
As one of the alternative embodiments of the present embodiment, the article 20 to be maintained may be an electronic product, such as a watch, a bracelet, a mobile phone, and the like. Referring to fig. 1 and fig. 2 together, in fig. 1, a dial of an intelligent watch is taken as an example, (a) is a gummed paper 10 consistent with the contour of the dial, (b) is the dial, a display screen groove for observing a display screen and a camera shooting through hole for allowing light of a camera to enter are arranged on the dial, and (c) after the gummed paper 10 is attached to the dial, the gummed paper 10 is a light-colored part 101 on the surface of the dial. After pressure maintaining, if the adhesive tape 10 appears in two different colors on the surface of the dial, namely the situation of (d) in fig. 1 appears, the light color part 101 shows that the pressure maintaining is insufficient here, the pressure maintaining is sufficient here on the surface of the dark color part 102, so that the pressure maintaining equipment can be adjusted, and the adhesive tape 10 with the same thickness is reused for pressure maintaining until the adhesive tape 10 appears in the dark color part 102 on the surface of the dial (the upper display screen groove and the camera shooting through hole of the dial are always light color and are out of discussion). Then, if the adhesive tape 10 with the thinner thickness exists, the adhesive tape 10 with the thinner thickness can be used to be attached to the surface of the dial, the pressure maintaining operation is continued, and the above steps are repeated until the adhesive tape 10 with the thinnest thickness (within the set thickness range) is used for maintaining the pressure, the light color part 101 does not appear on the adhesive tape 10, and at this time, the calibration of the pressure maintaining equipment is completed.
The embodiment of the invention also provides a pressure maintaining device, which comprises pressure maintaining equipment and the adhesive tape 10, wherein the adhesive tape 10 can be pre-attached to the object 20 to be maintained, and the adhesive tape 10 can be in different states according to different attaching tightness with the surface of the object 20 to be maintained. Thus, the adhesive tape 10 is attached to the surface of the object 20 to be pressure-maintained and the pressure maintaining operation is performed, so that the adhesive tape 10 presents different states according to different attaching tightness degrees with the surface of the object 20 to be pressure-maintained, and the balance degree of the pressure maintaining equipment is detected. In the specific application, the adhesive tape 10 may be a common transparent adhesive tape (may be colorless and transparent, and may also be non-colorless and transparent), and may also be a pressure color-changing adhesive tape, so as to more accurately detect the balance degree of the pressure maintaining device.
According to the method and the device for detecting the balance degree of the pressure maintaining equipment, provided by the embodiment of the invention, the adhesive paper 10 is attached to the surface of the object 20 to be subjected to pressure maintaining, then the object is placed into the pressure maintaining equipment for pressure maintaining, after the object to be subjected to pressure maintaining is taken out, the adhesive paper 10 presents a dark color part 102 and/or a light color part 101 (or changes color by using pressure color-changing adhesive paper), the dark color part 102 shows that the pressure maintaining at the position is sufficient, the light color part 101 shows that the pressure maintaining is insufficient, whether the pressure maintaining equipment is balanced is judged, and relevant parameters of the pressure maintaining equipment can be correspondingly adjusted according to the dark color part 102 and the light color part 101, so. In addition, elastic adhesive paper can be adopted, and the balance degree of the pressure maintaining equipment is further accurately measured by using the adhesive paper 10 with different thicknesses, so that the accurate correction of the pressure maintaining equipment is facilitated.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents or improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
