Detailed Description
In one aspect of the present application, a method of hardening a surface of a composite board is provided. With reference to fig. 1, it can be understood that the surface of the composite board 10 has a first area 100 and a second area 200 (in the description of the present application, it is to be noted that the terms "first" and "second" are only used for descriptive purposes, and are not understood to indicate or imply relative importance or implicitly indicate the number of indicated technical features, therefore, the feature defined as "first" and "second" may explicitly or implicitly include one or more of the features, and will not be repeated in the following description), the second area 200 has a camera accommodating area 210 therein, and a forward projected contour line of the camera accommodating area 210 in the thickness direction of the composite board 10 has a gap d with an edge of the second area 200, and with reference to fig. 2, it can be understood that the method may include the following steps:
s100: performing a first curtain coating process on the first region 100 of the composite board, wherein the first curtain coating process is performed under a condition that the composite board is placed in a horizontal direction.
Since the first region 100 of the composite board 10 does not have a camera accommodating region, the first region 100 has a high flatness as a whole, and there is no position where liquid accumulation is likely to occur in the entire first region 100, so that the first region 100 is first subjected to the first curtain coating process, and the first curtain coating process can form a hardening liquid on the surface of the first region 100.
Specifically, referring to fig. 3a, it can be understood that the first curtain coating process may have a first curtain coating line 11, and the first curtain coating line 11 may extend from one side of the composite board to the other side of the composite board and span the edge of the composite board. Through the above-mentioned curtain coating method, the whole first curtain coating process can be uniformly coated, and it should be noted that, after the hardening liquid is formed on the surface of the composite board 10, the hardening liquid can automatically level on the surface of the composite board 10 due to the surface tension thereof, and therefore, as can be understood by those skilled in the art, although the first curtain coating line 11 does not pass through each part of the first area 100, as can be seen from fig. 3b, after the first curtain coating process, the hardening liquid L can be formed on the whole surface of the first area 1001。
S200: and performing second curtain coating treatment on the second area of the composite board, wherein at least part of curtain coating sites of the second curtain coating treatment are located in the camera accommodating area, and the second curtain coating treatment is performed under the condition that the composite board is placed in the horizontal direction.
As can be seen from FIG. 3b, the second flow coating process has a second flow coating line 22, and the aforementioned flow coating sites are referred to as the flow coating linesAt a certain point on the second curtain coating line 22, at least part of the curtain coating sites of the second curtain coating process are located in the camera accommodating area 210, that is, the second curtain coating line 22 passes through the camera accommodating area 210. Thus, in the above-described curtain coating method, the surface of the first region 100 is completely covered with the curing liquid L during the first curtain coating process1Then, after the first curtain coating treatment is finished, second curtain coating treatment is carried out in the second area 200, so that the whole surface of the whole composite board 10 can be favorably curtain coated; in addition, since at least part of the second curtain coating sites of the second curtain coating process are also located in the camera accommodating area 210, the hardening liquid of the second curtain coating process also has a leveling effect, and the camera accommodating area 210 can be better curtain coated; meanwhile, when the hardening liquid for the second curtain coating process is leveled to the edge of the camera accommodating area 210, because the composite board 10 is horizontally placed, the hardening liquid automatically flows to the outer edge of the camera accommodating area 210 due to the self gravity effect of the hardening liquid, further flows to other parts of the second area 210, and finally forms the hardening liquid L with the first curtain coating process1Are in contact.
Specifically, referring to fig. 3b, it can be understood that the second flow coating line 22 of the second flow coating process may pass through the camera receiving area 210 from one side of the second area 200, extend to the other side of the second area 200, and span the edge of the composite board 10. By performing the second curtain coating process in the above-described manner, the hardening liquid of the second curtain coating process can be formed relatively uniformly in the second region 200 (see the hardening liquid L shown in fig. 3 c)2) Of course, it is also formed more uniformly in the camera accommodating area 210 (refer to the hardening liquid L shown in fig. 3 c)3) And the outer edge of the camera receiving area 210, thereby forming a hardening liquid on the entire surface of the composite board 10. Therefore, the method is simple and convenient to operate, easy to realize, easy to industrialize, low in cost and high in efficiency, and the edge of the camera accommodating area 210 of the composite board 10 is not easy to generate the shower coating effusionWhen the composite board 10 is used for manufacturing a housing of an electronic device, the composite board is not prone to cracking caused by excessive stress due to liquid loading by shower coating in the process after hardening, so that the yield of the method for manufacturing the housing of the electronic device is high, and the strength of the manufactured housing of the electronic device is also high.
In addition, further, the applicant has conducted further investigation and extensive experimental verification on the process parameters of the first curtain coating treatment and the second curtain coating treatment, and the first curtain coating treatment and the second curtain coating treatment can respectively and independently satisfy the following conditions:
it can be understood that the UV energy of the first curtain coating treatment and the second curtain coating treatment can be 550-650 mj/cm independently2Specifically, the UV energy may be 550mj/cm2、575mj/cm2、600mj/cm2、625mj/cm2Or 650mj/cm2And the like, so that the first curtain coating treatment and the second curtain coating treatment can be well cured after the hardening liquid is curtain coated by the UV energy within the range, and meanwhile, the UV energy is not too low in the range, so that incomplete curing is caused, the curtain coating hardness is not too low, and cracking is not caused in a crater area due to too high UV energy, so that the performance of the manufactured electronic equipment shell is poor.
It is understood that the IR leveling temperatures of the first and second curtain coating processes may each independently be 55 ℃ to 65 ℃, and specifically, the IR leveling temperature may be 55 ℃, 60 ℃, or 65 ℃, and the like. From this, through the IR levelling temperature in above-mentioned range, it neither can be too low and lead to the solvent to volatilize incompletely, also can not too high and lead to the diluent to volatilize too fast, and then makes first curtain coating handle and second curtain coating handle the flow mark or hydrops that appear curtaining.
It is to be understood that the leveling time of the first flow coating process and the second flow coating process may be each independently 360s to 480s, specifically 360s, 400s, 440s, 480s, or the like. From this, through the leveling time in the above-mentioned within range, it neither can be too short and lead to the flow mark, also can not be too long and lead to the hydrops, and then makes first curtain coating handle and second curtain coating handle the leveling effect that realizes the preferred.
It is to be understood that the linear speed of the first curtain coating process and the second curtain coating process may be 15Hz to 21Hz, and specifically, may be 15Hz, 18Hz, 21Hz, or the like, independently. From this, through the linear velocity in above-mentioned within range, it neither can be short excessively and lead to the flow mark, also can not be overlength and lead to the hydrops, and then makes first curtain coating handle and second curtain coating handle the leveling effect that realizes the preferred.
In addition, the cleaning manner of the first curtain coating process and the second curtain coating process and the specific type of the used hardening liquid may be a conventional cleaning manner and a conventional type of the hardening liquid, and a person skilled in the art may flexibly select the cleaning manner and the hardening liquid according to actual needs, and redundant description is not repeated herein. Therefore, the method is simple and convenient to operate, easy to realize and easy for industrial production.
The hardening liquid may have a solid content of 28% to 32%, and specifically, the hardening liquid may have a solid content of 28%, 29%, 30%, 31%, 32%, or the like. Therefore, the solid content of the hardening liquid is appropriate, the flow coating effect of the first flow coating treatment and the second flow coating treatment is good, and a stable hardening layer is formed on the surface of the composite board 10.
It is understood that, in the first curtain coating process and the second curtain coating process, conventional process conditions and parameters may be further included, and the process conditions and parameters that are not mentioned above may be performed according to corresponding process conditions and parameters in the conventional curtain coating process, and are not described in detail herein again.
In another aspect of the present application, a jig for hardening a surface of a composite board is provided. It is understood that the jig may include: the supporting part and the clamping part are suitable for fixing the composite board; the isolation part is positioned on one side, facing the composite board, of the support part. The jig has simple structure and lower cost, and is suitable for implementing the method for hardening the surface of the composite board.
Further, with reference to fig. 4a and 4b, it can be understood that the jig 5 may include a plurality of the clamping portions, and the jig may include: at least two first linear members 51, two of the first linear members 51 being disposed at intervals, and the first linear members 51 being configured as the support portion; a plurality of second linear members 52, the second linear members 52 being perpendicular to the first linear members 51, each of the first linear members 51 being connected to two of the second linear members 52, and two of the second linear members 52 connected to the same one of the first linear members 51 being configured as one of the clamping portions; a plurality of third linear members 53, wherein the third linear members 53 are configured as the isolation portion, each of the first linear members 51 is connected with at least one of the third linear members 53 (it should be noted that, as shown in fig. 4a and 4b, each of the first linear members 51 is connected with two of the third linear members 53, but it is understood by those skilled in the art that each of the first linear members 51 may be connected with only one of the third linear members 53 as long as the third linear member 53 supports the composite board 10), and the third linear member 53 is positioned between two of the second linear members 52 connected to and disposed adjacent to the same first linear member 51, the third linear member 53 having a length smaller than that of the second linear members 52. Therefore, the jig 5 is simple in structure and easy to produce, when the jig 5 is used for hardening the composite board 10, because the contact area between the jig 5 and the composite board 10 is small, hardening liquid is not easy to flow to the other surface of the composite board along the jig during curtain coating, and a protective layer is not required to be covered on the other surface of the composite board 10 during curtain coating, so that the process cost for hardening the composite board 10 is further reduced; meanwhile, the jig 5 can better enable the first curtain coating treatment and the second curtain coating treatment to be carried out under the condition that the composite board is placed along the horizontal direction, so that the phenomenon of liquid accumulation in curtain coating cannot be caused, and the curtain coating effect is better.
Further, with reference to fig. 5, it can be understood that the jig 5 may further include: a fourth linear member 54, said fourth linear member 54 being for fixing two of said first linear members 51. Specifically, the fourth linear member 54 may be a member directly connecting two first linear members 51 (the schematic structure is shown in fig. 5); the first linear component 51 may also be connected indirectly, for example, referring to fig. 6, the jig 5 may further include at least two fifth linear components 55, where the fifth linear components 55 are parallel to the first linear component 51; and a sixth linear member 56, the sixth linear member 56 connecting the fifth linear member 55 and the first linear member 51, the fourth linear member 54 fixing the two first linear members 51 by connecting the two fifth linear members 55. Furthermore, when the jig 5 is used to harden the composite board, the fourth linear member 54 does not contact with the composite board, so that the hardening liquid can be prevented from flowing from the edge of the composite board 10 to the other surface of the composite board 10 along the fourth linear member 54, and the other surface of the composite board 10 does not need to be covered with a protective layer during the coating process, thereby further saving the cost.
Additionally, still further, with reference to fig. 4a, 4b, 5 and 6, it can be understood that the two first linear members 51 are parallel to each other and form a first plane, and the second linear member 52 and the third linear member 53 are both perpendicular to the first plane, and the directions in which the second linear member 52 and the third linear member 53 extend are parallel to each other. Therefore, the jig is easy to form, the second linear component 52 can have a better supporting effect on the composite board 10, and the third linear component 53 can have a better fixing effect on the composite board 10, so that the effect of the curtain coating treatment is further improved.
Still further, it will be appreciated that a protective jacket may also be provided on the outer surface of the partition, for example, on the third linear member 53, to prevent damage to the composite panel 10 when the hardening process is performed.
In addition, it can be understood that the material forming the jig 5 may include a metal material, and the jig 5 may be manufactured through the steps of blanking, bending, and welding, so that the operation is simple and convenient, the implementation is easy, and the industrial production is easy.
It can be understood that, before the jig 5 is put into use, the jig 5 may be calibrated to make products of different batches have better consistency, and after the jig 5 is used to harden the composite board 10, the conventional operation steps of removing the composite board 10 from the jig 5, performing full inspection, covering a protective film, and the like may also be included, which are not described herein again.
