[0044] like Figure 1 As shown, Figure 1FIG. 1 shows the process of the protective film attaching method 1000 in the embodiment of the present disclosure. Figures 2 to 9 The protective film attaching method 1000 provided in the embodiment of the present disclosure includes the following steps S102 to S106.

[0045] Step S102, bonding the first surface of the base film 202 to the bonding connection surface 11 of the first fixture 10. The second surface of the base film 202 is bonded with a protective film 201. Exemplarily, the second surface of the base film 202 is bonded with a plurality of protective films 201, the plurality of protective films 201 are arranged in an array, and the arrangement positions of the plurality of protective films 201 are set corresponding to the arrangement positions of the plurality of lenses.

[0046] In step S103 , the bonding end 232 of the second fixture 20 is used to bond the side of the protective film 201 facing away from the base film 202 .

[0047] Step S104 , separating the protective film 201 from the base film 202 by using the adhesive end 232 . The adhesiveness of the adhesive end 232 is greater than the adhesiveness between the protective film 201 and the base film 202 .

[0048] Step S105 : using the second fixture 20 to bond the protective film 201 to the lens.

[0049] Step S106 , using the movable portion 22 and the lens to clamp the protective film 201 , and separating the adhesive end 232 from the protective film 201 .

[0050] In the protective film attaching method 1000 provided in the embodiment of the present disclosure, the protective film 201 is bonded to the base film 202, and the bonding connection surface 11 of the first fixture 10 is fully in contact with the base film 202 and bonded to the base film 202. The bonding end 232 of the second fixture 20 is fully in contact with the protective film 201 and bonded to the protective film 201. A force is applied to the second fixture 20 to separate from the first fixture 10. Since the viscosity of the bonding end 232 of the second fixture 20 is greater than the viscosity between the base film 202 and the protective film 201, the protective film 201 is separated from the base film 202. The base film 202 remains on the bonding connection surface 11 of the first fixture 10, and the protective film 201 is bonded to the bonding end 232 and moves with the second fixture 20. The protective film 201 of the bonding end 232 of the second fixture 20 is fully contacted with the lens so that the protective film 201 is bonded to the lens, and a force to separate the lens is applied to the contact portion 23 . The protective film 201 is pressed by the movable portion 22 so that the bonding end 232 is separated from the protective film 201 .

[0051] Exemplarily, when a plurality of second jigs 20 are operating, when a second jig 20 that has completed steps S103 to S104 is performing step S105 , other second jigs 20 may be performing S103 at the same time.

[0052] The protective film attaching method 1000 provided in the embodiment of the present disclosure makes the second jig 20 contact the first jig 10, so that the adhesive end 232 of the second jig 20 is attached to the protective film 201, and the protective film 201 at the adhesive end 232 is directly attached to the lens through the second jig 20. The protective film 201 will not cause wrinkles during the attachment process, and the operation is simple, which reduces the difficulty of manual attachment of the protective film 201.

[0053] See also Figure 2 In some embodiments, the protective film attaching method 1000 further includes step S101 : forming a roll material 200 using a base film 202 and a plurality of protective films 201 .

[0054] The coil 200 is sleeved on the auxiliary tool, wherein the bottom film 202 is provided with positioning holes 203 corresponding to the positioning posts 121 of the first fixture 10 ; and a plurality of protective films 201 are provided corresponding to a plurality of lenses.

[0055] With such a configuration, the coil 200 is easy to fix and convenient to use, and the positioning holes 203 of the bottom film 202 cooperate with the positioning posts 121 of the first fixture 10 for positioning, thereby improving the accuracy of attaching the protective film 201. Multiple protective films 201 are arranged corresponding to multiple lenses, so that multiple lenses can be attached to the film at the same time in one operation, which is conducive to improving the attachment efficiency of the protective film 201 and saving time and human resources.

[0056] In the protective film attaching method 1000 provided in the embodiment of the present disclosure, step S101 is performed first, and then steps S102 to S106 are performed.

[0057] Exemplarily, the edge portion 12 of the first fixture 10 is provided with a cutter head 122 for cutting the coil 200 .

[0058] Exemplarily, the process of attaching the protective film 201 is as follows: the base film 202 is provided with a positioning hole 203 that cooperates with the positioning column 121 of the first fixture 10, and multiple protective films 201 are pasted on the base film 202 according to the lens arrangement method. The protective film 201 and the base film 202 form a coil 200 that is sleeved on the auxiliary tool. The coil 200 can rotate along the axis on the auxiliary tool, which is convenient for cutting and use. The positioning column 121 of the first fixture 10 is manually embedded in the positioning hole 203 of the base film 202 of the coil 200, so that the bonding connection surface 11 is in full contact with the base film 202, and then the coil 200 is cut using the cutter head 122 of the first fixture 10. The bonding end 232 of the second fixture 20 is fully contacted with the protective film 201 and the protective film 201 is bonded. A force is applied to the second jig 20 to separate from the first jig 10. Since the viscosity of the bonding end 232 of the second jig 20 is greater than the viscosity between the base film 202 and the protective film 201, the protective film 201 is separated from the base film 202. The base film 202 remains on the bonding connection surface 11 of the first jig 10, and the protective film 201 is bonded to the bonding end 232 and moves with the second jig 20. The protective film 201 at the bonding end 232 of the second jig 20 is fully contacted with the lens so that the protective film 201 is bonded to the lens, and a force is applied to the contact portion 23 to separate from the lens. Since the movable portion 22 presses the lens, the bonding end 232 is separated from the protective film 201.

[0059] In some embodiments, the step of using the bonding end 232 of the second fixture 20 to bond the side of the protective film 201 facing away from the base film 202 includes: pressing the pressing end 231 along the first direction.

The second pressing of the pressing end 231 is conducive to the full contact between the protective film 201 and the lens, and a force is applied to the pressing end 231 in the first direction away from the protective film 201, so that the movable part 22 presses the lens module, and the bonding end 232 moves in the first direction away from the protective film 201, ensuring the separation of the bonding end 232 and the protective film 201.

[0063] Exemplarily, the process of attaching the protective film 201 is as follows: the base film 202 is provided with a positioning hole 203 that cooperates with the positioning column 121 of the first fixture 10, and multiple protective films 201 are pasted on the base film 202 according to the lens arrangement method, and the protective film 201 and the base film 202 form a coil 200 that is sleeved on the auxiliary tool. The coil 200 can rotate along the axis on the auxiliary tool, which is convenient for cutting and use. The positioning column 121 of the first fixture 10 is manually embedded in the positioning hole 203 of the base film 202 of the coil 200, so that the bonding connection surface 11 is in full contact with the base film 202, and then the cutter head 122 of the first fixture 10 is used to cut the coil 200. The bonding end 232 of the second fixture 20 is brought into contact with the protective film 201, and the pressing end 231 is pressed along the first direction so that the bonding end 232 is bonded to the protective film 201. A force is applied to the fixing portion 21 in the first direction away from the base film 202. Since the viscosity of the bonding end 232 of the second jig 20 is greater than the viscosity between the base film 202 and the protective film 201, the protective film 201 is separated from the base film 202. The base film 202 remains on the bonding connection surface 11 of the first jig 10, and the protective film 201 is bonded to the bonding end 232 and moves with the second jig 20. The protective film 201 of the bonding end 232 of the second jig 20 is brought into contact with the lens, the pressing end 231 is pressed in the first direction so that the protective film 201 is bonded to the lens, and a force is applied to the pressing end 231 in the first direction away from the protective film 201. Since the movable portion 22 presses the lens, the bonding end 232 is separated from the protective film 201.

[0064] See also Figures 3 to 8 The embodiment of the present disclosure provides a protective film attaching jig set 100, which includes a first jig 10 and a second jig 20.

By pressing the pressing end 231 of the contact part 23, the adhesion between the adhesive end 232 and the protective film 201 is strengthened, which is beneficial to the separation of the protective film 201 and the base film 202.

[0079] Exemplarily, the process of attaching the protective film 201 is as follows: the bottom film 202 is provided with a positioning hole 203 that cooperates with the positioning column 121 of the first fixture 10, and multiple protective films 201 are pasted on the bottom film 202 according to the lens arrangement. The protective film 201 and the bottom film 202 form a coil 200 and are sleeved on the auxiliary tool. The coil 200 can rotate along the axis on the auxiliary tool, which is convenient for cutting and use. The positioning column 121 of the first fixture 10 is manually embedded in the positioning hole 203 of the bottom film 202 of the coil 200, so that the bonding connection surface 11 is fully in contact with the bottom film 202, and then the cutter head 122 of the first fixture 10 is used to cut the coil 200. The first fixture 10 is installed in the first groove 31 and the lens module tray 300 is installed in the second groove 32. The side of the first fixture 10 with the bottom film 202 and the side of the lens module tray 300 with the lens are both placed upward along the first direction. The bonding connection surface 11 is located in the first groove 31, and the depth of the bonding connection surface 11 is less than the thickness of the protective film 201. The second jig 20 is placed on the surface of the first jig 10 so that the bonding end 232 contacts the protective film 201, and the pressing end 231 is pressed along the first direction so that the bonding end 232 adheres to the protective film 201. A force is applied to the fixing portion 21 in the first direction away from the base film 202. Since the viscosity of the bonding end 232 of the second jig 20 is greater than the viscosity between the base film 202 and the protective film 201, the protective film 201 is separated from the base film 202. The base film 202 remains on the bonding connection surface 11 of the first jig 10, and the protective film 201 adheres to the bonding end 232 and moves with the second jig 20. The lenses are arranged in order in the lens module tray 300, the second jig 20 is placed on the surface of the lens module tray 300, the protective film 201 of the bonding end 232 of the second jig 20 is brought into contact with the lens, the pressing end 231 is pressed along the first direction so that the protective film 201 is bonded to the lens, a force is applied to the pressing end 231 away from the protective film 201 along the first direction, and the bonding end 232 is separated from the protective film 201 because the movable part 22 presses the lens. The protective film 201 is attached to the lens.

[0080] See again Fig. 9 In some embodiments, the third fixture 30 further includes a plurality of fixing blocks 33, which are rotatably connected to the third fixture 30, and the plurality of fixing blocks 33 are distributed along a third direction on both sides of the first groove 31 for fixing the first fixture 10, and the third direction is perpendicular to the first direction and perpendicular to the second direction.

[0081] With such a configuration, the rotation of the fixing block 33 is conducive to placing the first fixture 10 into the first groove 31 , and is also convenient for fixing the first fixture 10 in the first groove 31 .

[0082] Exemplarily, the four fixing blocks 33 are divided into two pairs and distributed along the third direction on both sides of the first groove 31 for fixing the first fixture 10. In other embodiments, the number of the fixing blocks 33 may be two, six or more.

[0083] Exemplarily, the shape of the fixing block 33 is an angle formed by connecting two rectangles, and the fixing block 33 can rotate around the connection. When the angle of the fixing block 33 faces away from the first groove 31, it is used to place the first fixture 10; when the angle of the fixing block 33 points to the first groove 31, it is used to fix the first fixture 10.

[0084] See again Fig. 9 In some embodiments, the third fixture 30 is further provided with a plurality of first vacancies 34 and a plurality of second vacancies 35, and each pair of the plurality of pairs of first vacancies 34 is symmetrically distributed on both sides of the first groove 31 along the second direction; each pair of the plurality of pairs of second vacancies 35 is symmetrically distributed on both sides of the second groove 32 along the second direction; and the second fixture 20 is placed in a pair of first vacancies 34 or a pair of second vacancies 35.

[0085] In this configuration, a pair of first vacancies 34 or a pair of second vacancies 35 are used to place the second fixture 20 , which is beneficial to improving the accuracy of attaching the protective film 201 and making the attaching effect of the protective film 201 better.

[0086] It can be understood that the shape of the first vacancy 34 is the same as the shape of the second vacancy 35 , and both correspond to the shapes of the two ends of the third fixture 30 .

[0087] Exemplarily, the enclosed portion of the first space 34 and the enclosed portion of the second space 35 are both higher than the surface of the third fixture 30 .

[0088] For example, a second jig 20 is placed in a pair of first spaces 34 to bond the protective film 201, and then placed in a pair of second spaces 35 to bond the protective film 201 to the lens. Multiple second jigs 20 can be placed in multiple pairs of first spaces 34 to bond the protective film 201 at the same time, and at the same time, multiple second jigs 20 can be placed in multiple pairs of second spaces 35 to bond the protective film 201 to the lens at the same time.

[0089] See again Fig. 9 In some embodiments, the third fixture 30 is provided with a plurality of pick-and-place portions 36, and the plurality of pick-and-place portions 36 are distributed along the third direction on both sides of the first groove 31 for picking up and placing the first fixture 10; and the plurality of pick-and-place portions 36 are distributed along the third direction on both sides of the second groove 32 for picking up and placing the lens module tray 300.

[0090] With such arrangement, the pick-and-place portion 36 facilitates manual pick-and-place of the first fixture 10 and the lens module tray 300 , thereby improving the efficiency of attaching the protective film 201 .

[0091] Exemplarily, the taking and placing portion 36 is hollowed out to facilitate manual operation.

[0092] Exemplarily, a pick-and-place portion 36 is provided in the middle portion where the first groove 31 and the second groove 32 are arranged in parallel along the third direction, and pick-and-place portions 36 are provided at both end edges 12 of the third fixture 30 along the third direction.

[0093] In other embodiments, the pick-and-place portion 36 may also be snap-connected, clamped, or bolted for pick-and-place.

[0094] Exemplarily, the process of attaching the protective film 201 is as follows: the bottom film 202 is provided with a positioning hole 203 that cooperates with the positioning column 121 of the first fixture 10, and multiple protective films 201 are pasted on the bottom film 202 according to the lens arrangement method. The protective film 201 and the bottom film 202 form a roll 200 and are sleeved on the auxiliary tool. The roll 200 can rotate along the axis on the auxiliary tool, which is convenient for cutting and use. The positioning column 121 of the first fixture 10 is manually embedded in the positioning hole 203 of the bottom film 202 of the roll 200, so that the bonding connection surface 11 is fully in contact with the bottom film 202, and then the cutter head 122 of the first fixture 10 is used to cut the roll 200. The first jig 10 is installed in the first groove 31 through the pick-and-place part 36, the lenses are arranged in order in the lens module tray 300, and the lens module tray 300 is installed in the second groove 32 through the pick-and-place part 36. The first jig 10 with the bottom film 202 and the lens module tray 300 with the lens are both placed upward along the first direction. The bonding connection surface 11 is located in the first groove 31, and the depth of the bonding connection surface 11 is less than the thickness of the protective film 201. The first jig 10 is fixed to the first groove 31 by rotating the fixing block 33. The second jig 20 is placed in a pair of first vacancies 34 so that the bonding end 232 contacts the protective film 201, and the protective film 201 will lift the contact part 23 and the movable part 22 along the first direction, and the surface of the pressing end 231 of the contact part 23 will protrude from the surface of the fixed end. The protruding part of the pressing end 231 is gently pressed manually along the first direction so that the bonding end 232 is fully bonded to the protective film 201. A force is applied to the fixing portion 21 in the first direction away from the base film 202. Since the viscosity of the bonding end 232 of the second jig 20 is greater than the viscosity between the base film 202 and the protective film 201, the protective film 201 is separated from the base film 202. The base film 202 remains on the bonding connection surface 11 of the first jig 10, and the protective film 201 is bonded to the bonding end 232 and moves with the second jig 20. The second jig 20 is placed in a pair of second vacancies 35 so that the protective film 201 at the bonding end 232 contacts the lens. The lens will lift the contact portion 23 and the movable portion 22 in the first direction, and the surface of the pressing end 231 of the contact portion 23 will protrude from the surface of the fixing end. The protruding portion of the pressing end 231 is gently pressed manually in the first direction so that the protective film 201 is fully bonded to the lens. The contact part 23 is pulled up by the protruding part of the contact part 23. Since the movable part 22 presses the lens and the movable part 22 has no stickiness, when the contact part 23 is pulled up, the protective film 201 is separated from the contact part 23 due to the contact part with the movable part 22, so that the protective film 201 and the lens are bonded. At this time, the contact part 23 is continued to be pulled up. When the contact part 23 contacts the bottom of the first mounting groove 211 of the fixing part 21, the second fixture 20 will be lifted up as a whole, and the bonding operation of the protective film 201 is completed.
