For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] This embodiment provides a film attaching jig 100, as Figures 1 to 4 shown, including a base 110, a roller 120, a first positioning piece 130, a second positioning piece 140, and a positioning block 150 arranged on the base 110. A first positioning groove 131 is provided on the surface of the first positioning piece 130, and a second positioning groove 141 symmetrically arranged with the first positioning groove 131 is provided on the surface of the second positioning piece 140. The first positioning groove 131 and the second positioning groove 141 are used to respectively position two substrates 200 to be film-attached. A first positioning through groove and a second positioning through groove are provided on the first surface 153 of the positioning block 150. The first positioning through groove and the second positioning through groove are used to respectively position the film layer 300 to be attached on the substrate 200 to be film-attached. The roller 120 rolls along the film layer 300 to be attached and pushes the positioning block 150 to slide, so that the notch of the first positioning through groove is aligned with the notch of the first positioning groove 131, or the notch of the second positioning through groove is aligned with the notch of the second positioning groove 141.

[0030] The upper surface of the first positioning piece 130 is provided with a first positioning groove 131, and the lower surface is fixed on the base 110. The upper surface of the second positioning piece 140 is provided with a second positioning groove 141, and the lower surface is fixed on the base 110. The surface of the base 110 is divided into a C direction and a D direction perpendicular to each other. The first positioning piece 130 and the second positioning piece 140 are distributed along the C direction and are respectively located at opposite ends of the base 110. The edges of the first positioning piece 130 and the second positioning piece 140 that are close to each other have a connecting line along the C direction. The center line of the base 110 is a straight line passing through the midpoint of the connecting line and extending along the D direction. The first positioning groove 131 and the second positioning groove 141 are symmetric with respect to the center line of the base 110. The first surface 153 of the positioning block 150 is sequentially provided with a first positioning through groove and a second positioning through groove along the C direction. The second surface 154 opposite to the first surface 153 is slidably arranged on the base 110. The sliding direction of the positioning block 150 is the same as or opposite to the C direction. By sliding the positioning block 150, the notch of the first positioning through groove can be aligned with the notch of the first positioning groove 131, or the notch of the second positioning through groove can be aligned with the notch of the second positioning groove 141 in the E direction. The roller 120 is in a free state and can be in any position and move in any direction under manual operation. After the substrate 200 to be pasted with a film and the film layer 300 to be bonded are positioned, the roller 120 can roll along the film layer 300 to be bonded under manual drive to remove the air between the film layer 300 to be bonded and the substrate 200 to be pasted with a film, so that the film layer 300 to be bonded is completely bonded to the surface of the substrate 200 to be pasted with a film. During the rolling process, the roller 120 also drives the positioning block 150 to slide, preparing for positioning the film layer 300 to be bonded on another substrate 200 to be pasted with a film.

[0031] The above-mentioned film pasting fixture 100 includes two film pasting stations. The two film pasting stations can be used separately or cooperate with each other and be used alternately. For two symmetric film layers 300 to be bonded, they can be bonded in pairs to improve the operation efficiency. At the same time, the positioning block 150 can reciprocate along a fixed path and can move together with the roller 120 during use. During the forward movement of the roller 120, the film layer 300 to be bonded is pressed against the surface of the substrate 200 to be pasted with a film, and the positioning block 150 is driven to disengage from the film layer 300 to be bonded. The structure is simple, the cost is low, and the operation is convenient, reducing the influence of human factors and improving the accuracy of film pasting.

[0032] Taking the case where the two film pasting stations cooperate with each other and are used alternately as an example, such as Figure 2As shown, during use, two substrates 200 to be film - pasted can be respectively placed in the first positioning groove 131 and the second positioning groove 141. Then, slide the positioning block 150 to align the notch of the first positioning through - groove on the positioning block 150 with the notch of the first positioning groove 131. After alignment, place a film layer 300 to be bonded on the first positioning through - groove, with the film layer 300 to be bonded located above the substrate 200 to be film - pasted. The roller 120 rolls from one end of the film layer 300 to the other end (along the C direction), and at the same time, push the positioning block 150 to slide, as Figure 3 shown. When the roller 120 moves to the other end of the film layer 300 to be bonded, the notch of the second positioning through - groove just aligns with the notch of the second positioning groove 141. Then, place another film layer 300 to be bonded in the second positioning through - groove, move the roller 120 to one end of the other film layer 300 to be bonded, and the roller 120 rolls from one end of the other film layer 300 to the other end (along the direction opposite to the C direction), and at the same time, push the positioning block 150 to slide. When the roller 120 moves to the other end of the other film layer 300 to be bonded, the notch of the first positioning through - groove just aligns with the notch of the first positioning groove 131. Thus, the film - pasting of the two substrates 200 to be film - pasted is completed.

[0033] Optionally, in an implementable way of the embodiment of the present invention, as Figure 1 and Figure 2 shown, one end of the first positioning through - groove is located in the middle of the first surface 153 of the positioning block 150, and the other end extends to the first edge 1531 of the first surface 153. One end of the second positioning through - groove is located in the middle of the first surface 153 of the positioning block 150, and the other end extends to the second edge 1532 of the first surface 153 opposite to the first edge 1531. The inner walls of the first positioning through - groove and the second positioning through - groove for positioning the positioning part of the film layer 300 to be bonded cooperate with the edge of the film layer 300 to be bonded.

[0034] The openings of the first positioning through slot and the second positioning through slot both have opposite ends. Among them, one end of the opening of the first positioning through slot is located in the middle of the first surface 153, and the other end is located at the first edge 1531 of the first surface 153. One end of the opening of the second positioning through slot is located in the middle of the first surface 153, and the other end is located at the second edge 1532 of the first surface 153 opposite to the first edge 1531. The first positioning through slot and the second positioning through slot both include positioning portions. For the convenience of description, the positioning portion on the first positioning through slot is defined as the first positioning portion 1511, and the positioning portion on the second positioning through slot is defined as the second positioning portion 1521. The shapes and sizes of the inner walls of the first positioning portion 1511 and the second positioning portion 1521 are the same as the shapes and sizes of the edges of the film layer 300 to be adhered. After the film layer 300 to be adhered enters the first positioning portion 1511 or the second positioning portion 1521, it can be aligned with the substrate 200 to be pasted with the film. The first positioning through slot and the second positioning through slot are both semi-slots with side openings. Such a setting can not only position the film layer 300 to be adhered, but also facilitate the roller 120 to roll along the surface of the film layer 300 to be adhered and drive the positioning block 150 to slide.

[0035] Optionally, in an implementable manner of the embodiment of the present invention, the first positioning through slot and the second positioning through slot further include guiding portions connected to the positioning portions. The inner walls of the guiding portions are inclined, and the guiding portions are used to increase the openings of the first positioning through slot and the second positioning through slot.

[0036] The first positioning through slot and the second positioning through slot both include guiding portions connected to the positioning portions. For the convenience of description, the guiding portion on the first positioning through slot is defined as the first guiding portion 1512, and the guiding portion on the second positioning through slot is defined as the second guiding portion 1522. The first guiding portion 1512 is connected to the first positioning portion 1511, and the second guiding portion 1522 is connected to the second positioning portion 1521. The inner walls of the first guiding portion 1512 and the second guiding portion 1522 are both in an inclined state, and the inclined direction is the direction in which the openings of the first positioning through slot and the second positioning through slot are increased. The film layer 300 to be adhered enters the first positioning through slot or the second positioning through slot from the first guiding portion 1512 or the second guiding portion 1522 and slides along the inner wall of the first guiding portion 1512 or the second guiding portion 1522, and then enters the first positioning portion 1511 or the second positioning portion 1521. The setting of the guiding portion facilitates the placement and positioning of the film layer 300 to be adhered.

[0037] Optionally, in an implementable manner of the embodiment of the present invention, the inner walls of the first positioning groove 131 and the second positioning groove 141 respectively cooperate with the edges of the substrate 200 to be pasted with the film.

[0038] The shapes and sizes of the inner walls of the first positioning groove 131 and the second positioning groove 141 are respectively the same as the shapes and sizes of the edges of the substrate 200 to be film-attached. During use, the substrate 200 to be film-attached is placed into the first positioning groove 131 or the second positioning groove 141, and the positioning of the substrate 200 to be film-attached can be completed.

[0039] Optionally, in an implementable manner of the embodiment of the present invention, as Figure 1 and Figure 5 shown, the depths of both the first positioning groove 131 and the second positioning groove 141 are less than the thickness of the substrate 200 to be film-attached. A relief groove 155 is provided on the second surface 154 of the positioning block 150 opposite to the first surface 153. The bottom of the relief groove 155 is connected to the bottoms of the first positioning through groove and the second positioning through groove, and the bottom edges of the first positioning through groove and the second positioning through groove are located inside the bottom edge of the relief groove 155. The depth of the relief groove 155 is equal to the height by which the substrate 200 protrudes from the openings of the first positioning through groove and the second positioning through groove.

[0040] The first positioning piece 130 and the second positioning piece 140 have the same thickness, and the depths of the first positioning groove 131 and the second positioning groove 141 are equal. After the substrate 200 to be film-attached is placed into the first positioning groove 131 and the second positioning groove 141, its surface protrudes from the upper surfaces of the first positioning piece 130 and the second positioning piece 140. To avoid interference between the positioning block 150 and the substrate 200 to be film-attached, a relief groove 155 is provided on the second surface 154 of the positioning block 150. The depth of the relief groove 155 is equal to the difference between the depth of the substrate 200 and the depth of the first positioning through groove. When the first positioning through groove is aligned with the first positioning groove 131, the bottom of the relief groove 155 contacts the upper surface of the substrate 200, and the substrate 200 is limited in the E direction. The two ends of the opening of the relief groove 155 respectively extend to the opposite two side walls of the positioning block 150, and the bottoms of the first positioning through groove and the second positioning through groove are both located inside the bottom edge of the relief groove 155. With such a setting, it not only does not affect the reciprocating sliding of the positioning block 150 and the positioning of the film layer 300 to be attached, but also enables the relief groove 155 to limit the two substrates 200 to be film-attached at the same time.

[0041] Optionally, in an implementable manner of the embodiment of the present invention, as Figure 3 and Figure 4As shown, a stop groove 156 is provided on the second surface 154 of the positioning block 150 opposite to the first surface 153. A stop bar 111 is provided on the base 110. The stop bar 111 is located within the stop groove 156. The stop bar 111 abuts against the first side wall 1561 of the stop groove 156. The notch of the first positioning through groove is aligned with the notch of the first positioning groove 131. The stop bar 111 abuts against the second side wall 1562 of the stop groove 156. The notch of the second positioning through groove is aligned with the notch of the second positioning groove 141.

[0042] A stop groove 156 is provided on the second surface 154 of the positioning block 150 that contacts the base 110. Correspondingly, a stop bar 111 is fixedly provided on the upper surface of the base 110. The upper part of the stop bar 111 extends into the stop groove 156. The groove width of the stop groove 156 in the C direction is greater than the width of the stop bar 111 in the C direction. In this way, the positioning block 150 can slide back and forth on the base 110 and will no longer move along the current movement direction after the side wall of the stop groove 156 abuts against the side wall of the stop bar 111. The opposite first side wall 1561 and second side wall 1562 of the stop groove 156 respectively limit the two extreme positions of the positioning block 150 in the C direction. When the stop bar 111 abuts against the first side wall 1561 of the stop groove 156, the positioning block 150 is in the first extreme position. When the stop bar 111 abuts against the second side wall 1562 of the stop groove 156, the positioning block 150 is in the second extreme position. By adjusting the distance between the first side wall 1561 and the second side wall 1562, when the positioning block 150 is in the two extreme positions, the notch of the first positioning through groove is aligned with the notch of the first positioning groove 131, or the notch of the second positioning through groove is aligned with the notch of the second positioning groove 141. During use, only need to push the positioning block 150 to the extreme position, the operation is simple, not affected by human factors, effectively improving the film sticking accuracy and film sticking efficiency.

[0043] Optionally, in an implementable manner of the embodiment of the present invention, it further includes a bolt and a nut. A first installation groove 112 is provided on the base 110. A strip-shaped hole is provided at the bottom of the first installation groove 112. The extending direction of the strip-shaped hole is the same as the sliding direction of the positioning block 150. The stop bar 111 is arranged in the first installation groove 112. An installation hole corresponding to the strip-shaped hole is provided on the stop bar 111. The bolt sequentially passes through the installation hole and the strip-shaped hole and is threadedly connected to the nut.

[0044] The strip-shaped hole is located in the first installation groove 112 of the base 110. The groove width of the first installation groove 112 along the C direction is greater than the width of the stop bar 111 along the C direction. A strip-shaped hole is provided at the bottom of the first installation groove 112. The strip-shaped hole penetrates through two opposite surfaces of the base 110, and the length direction of the strip-shaped hole is the same as the C direction. When fixing the stop bar 111, the bolt sequentially passes through the installation hole and the strip-shaped hole from the upper surface of the stop bar 111, and then is threadedly connected to the nut below the strip-shaped hole. By changing the position of the stop bar 111 in the C direction, the two limit positions of the positioning block 150 can be adjusted to finely adjust the positioning block 150 and ensure the position accuracy of the first positioning through groove and the second positioning through groove in the C direction.

[0045] Optionally, in an implementable manner of the embodiment of the present invention, two second installation grooves 113 are further provided on the base 110. The first positioning piece 130 and the second positioning piece 140 are respectively located in the two second installation grooves 113, and the surfaces of the first positioning piece 130 and the second positioning piece 140 are flush with the surface of the base 110.

[0046] The first positioning piece 130 and the second positioning piece 140 are respectively located in the two second installation grooves 113 on the base 110. The groove depth of the second installation groove 113 is the same as the thickness of the first positioning piece 130 and the second positioning piece 140. The first positioning piece 130 and the second positioning piece 140 are installed in the second installation groove 113, and their upper surfaces are flush with the surface of the base 110. In this way, interference between the first positioning piece 130 and the second positioning piece 140 and the positioning block 150 can be avoided, and the positioning block 150 can slide reciprocally on the surface of the base 110.

[0047] Optionally, in an implementable manner of the embodiment of the present invention, there is a gap between the inner wall of the second installation groove 113 and the first positioning piece 130 and the second positioning piece 140.

[0048] The size of the second installation groove 113 is larger than the size of the first positioning piece 130 and the second positioning piece 140. After the first positioning piece 130 and the second positioning piece 140 are installed in the second installation groove 113, there are gaps between each edge of the first positioning piece 130 and the second positioning piece 140 and the inner wall of the second installation groove 113, so that the positions of the first positioning piece 130 and the second positioning piece 140 in the second installation groove 113 can be adjusted to ensure the position accuracy of the first positioning groove 131 and the second positioning groove 141 in the C direction and the D direction.

[0049] Optionally, in an implementable manner of the embodiment of the present invention, as Figure 1As shown, two side rail bars 114 are oppositely arranged on the base 110.
