Description

Technical Field

[0001] The present application relates to the technical field of a protective film preparation device, and more specifically, to a production system of a hardening liquid for a hardened film. Background Art

[0002] In recent years, with the continuous development of electronic products in the mobile phone industry, various new electronic products have emerged one after another. Electronic products are generally covered with a protective film. The general structure of the protective film is that the top layer is a PET coated 3μm hardened coating, the middle layer is a 45μm semi-cured coating, and the bottom layer is a 25μm silicone layer and a fluorine film.

[0003] The hardened coating is formed by coating the hardening liquid on the semi-cured coating. Due to different surface tensions during the coating process, the resin of the hardening liquid is not fully dispersed, resulting in more and larger crystal points in the hardened coating. Utility Model Content

[0004] The purpose of the present application is to provide a production system of a hardening liquid for a hardened film, so as to improve the technical problem that a hardened coating formed by coating the existing hardening liquid has many large crystal points.

[0005] In the first aspect, an embodiment of the present application provides a production system for a hardening liquid for a hardening film, including a dispersion device and a filtering device. The dispersion device includes a dispersion barrel, a dispersion component and a driving component. The bottom of the dispersion barrel is an arc-shaped structure. The dispersion component is arranged in the dispersion barrel. The dispersion component includes a plurality of dispersion disks stacked up and down, and each dispersion disk has a plurality of dispersion blades arranged circumferentially at the edge. The driving component is connected to the dispersion component and drives the dispersion component to rotate. The filtering device is arranged at the rear end of the dispersion device. The filtering device is connected to the dispersion barrel, and is used to filter the hardening liquid after dispersion treatment by the dispersion device.

[0006] In the above implementation process, the driving component drives the multiple dispersion disks stacked up and down to rotate so as to disperse the hardening liquid more efficiently. At the same time, the dispersion barrel with an arc-shaped structure at the bottom can avoid dead corners and assist in dispersing the hardening liquid more completely. The hardening liquid after sufficient and efficient dispersion treatment is then filtered through a filtering device to filter out particulate matter and bubbles in the hardening liquid, thereby reducing the appearance of crystal points in the hardened coating formed by the hardening liquid coating.

[0007] In a possible implementation, the filtering device includes at least three levels of filters, which are connected in sequence, the pore size of the first filter is 8-10 μm, the pore size of the second filter is 1-2 μm, and the pore size of the third filter is 0.1-0.2 μm. The three-stage filtration can filter out larger particles, smaller particles and bubbles in sequence, and the filtration is more complete, making the hardening liquid cleaner, and further reducing the appearance of crystal points in the hardened coating formed by the subsequent hardening liquid coating.

[0008] In a possible implementation, the dispersion leaves include a plurality of first dispersion leaves and a plurality of second dispersion leaves, the first dispersion leaves and the second dispersion leaves are arranged alternately at intervals; the first dispersion leaves are bent upward, and the second dispersion leaves are bent downward. By alternately arranging a plurality of first dispersion leaves bent upward and a plurality of second dispersion leaves bent downward, the dispersion area of ​​the hardening liquid can be increased, and the dispersion effect of the hardening liquid can be further improved.

[0009] In a possible implementation, the first dispersing leaf includes a first connecting leaf and a first extending leaf, the first connecting leaf is connected to the edge of the dispersing disk and extends outward, the first extending leaf is connected to an end of the first connecting leaf away from the dispersing disk, and the first dispersing leaf is bent upward at the first connecting leaf and the first extending leaf, and the extending direction of the first extending leaf forms an angle of 100°-160° with the horizontal direction of the dispersing disk. By extending the first extending leaf to form an angle of 100°-160° with the horizontal direction of the dispersing disk, the dispersing area is further increased, and the dispersing effect on the hardening liquid is improved.

[0010] In a possible implementation, the second dispersing leaf includes a second connecting leaf and a second extending leaf, the second connecting leaf is connected to the edge of the dispersing disk and extends outward, the second extending leaf is connected to an end of the second connecting leaf away from the dispersing disk, and the second dispersing leaf is bent downward at the second connecting leaf and the second extending leaf, and the extending direction of the second extending leaf forms an angle of 100°-160° with the horizontal direction of the dispersing disk. By extending the second extending leaf to form an angle of 100°-160° with the horizontal direction of the dispersing disk, the dispersing area is further increased, and the dispersing effect on the hardening liquid is improved.

[0011] In a possible implementation, the lengths of the first extension leaf and the second extension leaf are both 3-8 cm. An appropriate length is conducive to efficient dispersion of the hardening liquid and avoids excessive resistance.

[0012] In a possible implementation, the connection between the first connecting leaf and the first extension leaf is defined as a first connecting line, and the connection between the second connecting leaf and the second extension leaf is defined as a second connecting line. The first connecting line and the second connecting line both have a first end and a second end. Along the circumference of the dispersion disk, in each of the first connecting line and the second connecting line, the distance between the first end and the edge of the dispersion disk is smaller than the distance between the second end and the edge of the dispersion disk. The dispersion disk and the plurality of first dispersion leaves and the plurality of second dispersion leaves rotate to disperse the hardening liquid. The first connecting leaf and the first extension leaf can disperse the hardening liquid along the rotation direction of the hardening liquid, thereby reducing resistance and improving the dispersion effect of the hardening liquid.

[0013] In a possible implementation, along the circumference of the dispersion disk, the width of the first dispersion leaf and the second dispersion leaf are both 10-20 cm. Appropriate widths can be used to set an appropriate number of first dispersion leaves and second dispersion leaves, which is conducive to efficient dispersion of the hardening liquid.

[0014] In a possible implementation, the diameters of the multiple stacked dispersion discs decrease from top to bottom, and the diameter of the dispersion barrel is adapted to the diameters of the multiple dispersion discs and decreases from top to bottom. This facilitates all-round dispersion of the hardening liquid in the dispersion barrel, avoids dead corners, and disperses the hardening liquid more completely and efficiently.

[0015] In a possible implementation, the dispersion barrel is a hemispherical structure or a hemispherical structure, which can avoid dead corners and facilitate complete dispersion of the hardening liquid. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] A protective film is usually attached to electronic products. The top layer of the protective film is a 3μm hardened PET coating, the middle layer is a 45μm semi-cured coating, and the bottom layer is a 25μm silicone layer and a fluorine film.

[0030] The hardened coating is formed by coating the hardening liquid on the semi-cured coating. Due to different surface tensions during the coating process, the resin of the hardening liquid is not fully dispersed, resulting in more and larger crystal points in the hardened coating.

[0031] The present application intends to improve the technical problem that the hardened coating formed by the existing hardening liquid coating has many large crystal points, and proposes a production system of hardening liquid for hardening film, such as Figure 1 As shown, a production system of hardening liquid for hardening film includes: a dispersion device 1 and a filtering device 2. The dispersion device 1 includes a dispersion barrel 10, a dispersion component 11 and a driving component 12. The bottom of the dispersion barrel 10 is an arc-shaped structure. The dispersion component 11 is arranged in the dispersion barrel 10. The dispersion component 11 includes a plurality of dispersion disks 111 stacked up and down, and each dispersion disk 111 is circumferentially provided with a plurality of dispersion leaves; the driving component 12 is connected to the dispersion component 11 and drives the dispersion component 11 to rotate. The filtering device 2 is arranged at the rear end of the dispersion device 1. The filtering device 2 is connected to the dispersion barrel 10 and is connected to the dispersion barrel 10 for filtering the hardening liquid after dispersion treatment by the dispersion device 1.

[0032] The driving component 12 drives the multiple dispersion disks 111 stacked up and down to rotate so as to disperse the hardening liquid more efficiently. At the same time, the dispersion barrel 10 with an arc-shaped structure at the bottom can avoid dead corners and assist in dispersing the hardening liquid more completely. The hardening liquid after sufficient and efficient dispersion treatment is then filtered through the filtering device 2 to filter out particulate matter and bubbles in the hardening liquid, thereby reducing the appearance of crystal points in the hardened coating formed by the hardening liquid coating.

[0033] In some embodiments, at least four dispersion discs 111 are provided. As an example, the dispersion discs 111 may be provided in a number that is not limited to 4, 5, 6, 7, or 8. A plurality of dispersion discs 111 can improve the dispersion effect and efficiency of the hardening liquid.

[0034] In some embodiments, the interval between each two dispersion disks 111 is 3-4 cm. It should be noted that the interval between the two dispersion disks 111 can be set according to actual needs. It avoids the contact between the two dispersion disks 111 and is convenient to set a suitable number of dispersion disks 111, so that the dispersion effect and efficiency are higher.

The pore size of the first filter 20 is 8-10 μm, the pore size of the second filter 21 is 1-2 μm, and the pore size of the third filter 22 is 0.1-0.2 μm. It should be noted that in other embodiments, the filter device 2 may also include a four-stage filter or a five-stage filter. The three-stage filtration can filter and remove larger particles, smaller particles and bubbles in sequence, and the filtration is more complete to make the hardening liquid cleaner, further reducing the appearance of crystal points in the hardening coating formed by the subsequent application of the hardening liquid. At the same time, clogging can be reduced by at least three-stage filtration.

The plurality of first dispersing leaves 112 bent upward and the plurality of second dispersing leaves 113 bent downward arranged alternately at intervals can increase the dispersing area of ​​the hardening liquid and further improve the dispersing effect of the hardening liquid.

[0038] In some embodiments, the number of the first dispersing leaves 112 and the second dispersing leaves 113 are 10-30. As an example, the number of the first dispersing leaves 112 and the second dispersing leaves 113 can be, but are not limited to, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30.

[0039] In some embodiments, the first dispersing leaf 112 includes a first connecting leaf 1121 and a first extending leaf 1122, the first connecting leaf 1121 is connected to the edge of the dispersing disk 111 and extends outward, the first extending leaf 1122 is connected to the end of the first connecting leaf 1121 away from the dispersing disk 111, and the first dispersing leaf 112 is bent upward at the first connecting leaf 1121 and the first extending leaf 1122, and the extending direction of the first extending leaf 1122 forms an angle of 100°-160° with the horizontal direction of the dispersing disk 111. As an example, the extending direction of the first extending leaf 1122 and the horizontal direction of the dispersing disk 111 may form, but is not limited to, an angle of 100°, 110°, 120°, 130°, 140°, 150°, or 160°. The first extending leaf 1122 extends to form an angle of 100°-160° with the horizontal direction of the dispersing disk 111, further increasing the dispersing area and improving the dispersing effect on the hardening liquid.

[0040] In some embodiments, the second dispersing leaf 113 includes a second connecting leaf 1131 and a second extending leaf 1132, the second connecting leaf 1131 is connected to the edge of the dispersing disk 111 and extends outward, the second extending leaf 1132 is connected to the end of the second connecting leaf 1131 away from the dispersing disk 111, and the second dispersing leaf 113 is bent downward at the second connecting leaf 1131 and the second extending leaf 1132, and the extending direction of the second extending leaf 1132 forms an angle of 100°-160° with the horizontal direction of the dispersing disk 111. As an example, the extending direction of the second extending leaf 1132 and the horizontal direction of the dispersing disk 111 may form, but is not limited to, an angle of 100°, 110°, 120°, 130°, 140°, 150°, or 160°. The second extending leaf 1132 extends to form an angle of 100°-160° with the horizontal direction of the dispersing disk 111, further increasing the dispersing area and improving the dispersing effect on the hardening liquid.

[0041] In some embodiments, the lengths of the first extension leaf 1122 and the second extension leaf 1132 are both 3-8 cm. As an example, the lengths of the first extension leaf 1122 and the second extension leaf 1132 can be, but are not limited to, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, and 8 cm. An appropriate length is conducive to efficient dispersion of the hardening liquid and avoids excessive resistance.

[0042] In some embodiments, Figure 3-Figure 4As shown, the connection between the first connecting leaf 1121 and the first extension leaf 1122 is defined as the first connecting line 1123, and the connection between the second connecting leaf 1131 and the second extension leaf 1132 is defined as the second connecting line 1133. The first connecting line 1123 and the second connecting line 1133 both have a first end 114 and a second end 115. Along the circumference of the dispersion disk 111, in each of the first connecting line 1123 and the second connecting line 1133, the distance h1 between the first end 114 and the edge of the dispersion disk 111 is smaller than the distance h2 between the second end 115 and the edge of the dispersion disk 111. The dispersion disk 111 and the plurality of first dispersion leaves 112 and the plurality of second dispersion leaves 113 rotate to disperse the hardening liquid. The first connecting leaf 1121 and the first extension leaf 1122 can disperse the hardening liquid along the rotation direction of the hardening liquid, reduce resistance, and improve the dispersion effect of the hardening liquid.

[0043] In some embodiments, along the circumference of the dispersion disk 111, the width of the first dispersion leaf 112 and the second dispersion leaf 113 are both 10-20 cm. As an example, the width of the first dispersion leaf 112 and the second dispersion leaf 113 can be, but not limited to, set to 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 15 cm, 16 cm, 17 cm, 18 cm, 19 cm, 20 cm. It should be noted that the width of the first dispersion leaf 112 and the second dispersion leaf 113 is actually adjusted according to the diameter of different dispersion disks 111. The appropriate width can be set to an appropriate number of first dispersion leaves 112 and second dispersion leaves 113, which is conducive to the efficient dispersion of the hardening liquid.

[0044] In some embodiments, the diameters of the multiple stacked dispersion plates 111 decrease from top to bottom, and the diameter of the dispersion barrel 10 is adapted to the diameters of the multiple dispersion plates 111 and decreases from top to bottom.

[0046] The hardening liquid is introduced into the dispersion barrel 10, and the driving assembly 12 is started to drive the multiple dispersion discs 111 to rotate to disperse the hardening liquid. The multiple first dispersion leaves 112 and the multiple second dispersion leaves 113 on each dispersion disc 111 disperse the hardening liquid efficiently. At the same time, since the bottom of the dispersion barrel 10 is an arc-shaped structure, the diameters of the multiple stacked dispersion discs 111 decrease from top to bottom. The diameter of the dispersion barrel 10 is adapted to the diameter of the multiple dispersion discs 111 and decreases from top to bottom, which can avoid dead angles and make the multiple dispersion discs 111 The hardening liquid in the dispersion barrel 10 can be dispersed more completely in all directions; the completely dispersed hardening liquid is pumped into the filtering device 2 through the liquid pump 3 for filtration, first filtered through a first filter 20 with a pore size of 8-10μm to remove larger particles, then filtered through a second filter 21 with a pore size of 1-2μm to remove smaller particles, and then filtered through a third filter 22 with a pore size of 0.1-0.2μm to remove bubbles, and finally stored in the coating barrel 4, so that the hardening liquid is cleaner, so as to reduce the appearance of crystal points in the hardened coating formed by the hardening liquid coating.
