DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0049] In the related art, the manual dot screen jig used for dot screen detection needs to manually align the screen. This method completely relies on manual judgment of the position of the screen, which has two disadvantages. On the one hand, it is necessary to manually pre-judge the alignment, and it takes a long time to crimp each screen, which wastes production capacity. On the other hand, the screen crimping easily causes the electrical connection point between the screen and the crimping head on the dot screen jig to be misaligned, resulting in abnormal dot screen display or screen burn problems. In order to solve this technical problem, the present application provides a dot screen jig.

[0050] The present application is described in detail below with reference to the accompanying drawings and implementation methods.

[0051] See also Figure 1 and Figure 2 , Figure 1 is a top view of an embodiment of the point screen fixture provided by the present application, Figure 2 It is a schematic diagram of the process of positioning the screen on the dot screen fixture provided in the present application. The dot screen fixture 10 includes a dot screen carrier 100 and a positioning plate 200.

[0052] Combination Figure 3 , Figure 3 yes Figure 1 The top view of the screen dot platform in the screen dot fixture, the screen dot platform 100 has a bearing surface 101, and the bearing surface 101 is provided with a crimping head 110 for crimping the screen body 20.

[0053] The screen 20 may be a component with display function in various electronic products (mobile phones, tablet computers, televisions, smart watches, etc.). Optionally, the screen 20 is an OLED (Organic Light-Emitting Diode) display screen. The crimping head 110 is crimped to the screen 20 so that the crimping head 110 is in contact with the electrical connection point of the screen 20, so that the screen-lighting stage 100 provides various electrical signals to the screen 20 to light up the screen 20.

[0054] Combination Figure 4 , Figure 4 yes Figure 1 A top view of the positioning plate in the dot screen fixture, the positioning plate 200 is stacked with the dot screen carrier 100 and positioned on the dot screen carrier 100, the positioning plate 200 is provided with a notch 201, the contour line 202 of the notch 201 close to the bearing surface 101 is used to adapt to the outer contour of the screen body 20, the notch 201 includes a first side wall 211, and the first side wall 211 is located on the side of the notch 201 away from the crimping head 110 in the first direction. Figure 5 , Figure 5 yes Figure 1 In the AA cross-sectional view, a first angle α is formed between the first side wall 211 and the portion of the bearing surface 101 located outside the notch 201. The first angle α is an acute angle, so that the screen body 20 slides into the notch 201 along the first direction from the side of the first side wall 211 away from the crimping head 110. The process of the screen body 20 sliding from the first side wall 211 into the notch 201 can be seen in Figure 2 .

[0055] It can be seen that the present application sets a positioning plate 200 positioned on the dot screen carrier 100. Since the positioning plate 200 is pre-positioned on the dot screen carrier 100, as long as the screen body 20 slides into the notch 201 of the positioning plate 200, the outer contour of the screen body 20 is aligned with the contour line 202 on the side of the notch 201 close to the bearing surface 101, the positioning plate 200 is accurately positioned. The present application uses the positioning plate 200 to accurately align the position of the screen body 20 on the dot screen carrier 100, thereby avoiding the problem of misalignment between the screen body 20 and the crimping joint 110, which may cause abnormal dot screen detection display or burns of the screen body 20. In addition, the dot screen fixture 10 of the present application can achieve rapid positioning of the screen body 20 through the positioning plate 200, thereby increasing the dot screen efficiency.

[0056] In addition, the third side wall 213 of the present application forms a slope structure, and the screen body 20 can more easily slide into the notch 201 along the third side wall 213, and the positioning speed of the screen body 20 is faster. In the related art, when the screen body 20 is aligned, the screen body 20 is aligned by sliding the entire surface of the screen body 20 against the bearing surface 101 of the point screen carrier 100. The friction between the screen body 20 and the bearing surface 101 is relatively large, and the sliding of the screen body 20 is relatively laborious. In the present application, the screen body 20 slides into the notch 201 along the slope formed by the third side wall 213, and a section of suspension is formed between the front end of the screen body 20 and the edge of the third side wall 213 away from the bearing surface 101. Therefore, the screen body 20 does not slide against the bearing surface 101 on its entire surface, which reduces the friction between the screen body 20 and the bearing surface 101 and is also conducive to the rapid sliding of the screen body 20 to achieve positioning. The front end of the screen body 20 refers to an end of the screen body 20 that faces the crimping head 110 when the screen body 20 slides into the notch 201 .

[0057] It should be noted that the outer contour of the screen body 20 is aligned with the contour line 202 on the side of the notch 201 close to the bearing surface 101, which does not mean that the contour line 202 on the side of the notch 201 close to the bearing surface 101 needs to be completely consistent with the outer contour of the screen body 20. The contour line 202 and the outer contour of the screen body 20 may also be partially misaligned (the misaligned part requires the contour line 202 to be located outside the outer contour of the screen body 20), for example Figure 2 As shown, the outer contour of the screen body 20 has chamfers at the corners, while the contour line 202 is not provided with chamfers at the corners, but the positioning of the screen body 20 can still be achieved.

[0058] Furthermore, the first angle α is between 25° and 35°.

[0059] When the first angle α is small, it will be more difficult for the screen body 20 to slide into the notch 201 through the first side wall 211, and the time to slide into the notch 201 will increase, which will lead to a decrease in the efficiency of point screen detection. However, at the same time, when the screen body 20 slides into the notch 201 through the first side wall 211, the front end of the screen body 20 and the edge of the screen body 20 that contacts the first side wall 211 are in a suspended state. When a person presses the screen body 20 into the notch 201 with his hand, it will cause the screen body 20 to bend. When the first angle α is small, the first side wall 211 can support the screen body 20 to ensure that the bending degree of the screen body 20 is not too large, so the screen body 20 is not easy to break. In other words, the smaller the first angle α, the more difficult it is for the screen body 20 to slide into the notch 201 through the first side wall 211, but the screen body 20 is also less likely to break.

[0060] When the first angle α is large, the screen body 20 does not need to work hard when sliding into the notch 201 through the first side wall 211, and the screen body 20 can quickly slide into the notch 201, but at the same time, the supporting effect of the first side wall 211 on the screen body 20 disappears, and the screen body 20 is easy to break when sliding into the notch 201 through the first side wall 211. In other words, the larger the first angle α is, the easier it is for the screen body 20 to slide into the notch 201 through the first side wall 211, but the screen body 20 is also more likely to break.

[0061] The present application limits the size of the first angle α to a special range of 25° to 35°, while taking into account the speed of the screen 20 when sliding in and the screen 20 not breaking, thereby achieving the effect that the screen 20 slides in at a faster speed while the screen 20 is not easily broken.

[0062] Therefore, the screen dot fixture of the present application is particularly suitable for performing screen dot detection on a flexible screen.

[0063] Furthermore, the first angle α is between 30° and 35°. 30° to 35° is the optimal range of the first angle α. It only takes a few seconds for the screen body 20 to slide into the notch 201 through the first side wall 211 and achieve accurate positioning. In the prior art, the position of the screen body 20 is completely dependent on manual judgment for crimping and alignment, which usually takes more than ten seconds or even twenty seconds. The present application greatly improves the efficiency of screen tapping by setting a special range of values ​​for the slope of the first side wall 211. It has been verified through experiments that when the first angle α of the present application is in the range of 30° to 35°, it can ensure that the screen body 20 reaches the maximum sliding speed without breaking.

[0064] Further, see again Figure 1 and Figure 4 The notch 201 also includes a second side wall 212 and a third side wall 213, the second side wall 212 and the third side wall 213 are spaced apart, the first side wall 211 is connected between the second side wall 212 and the third side wall 213, and the first side wall 211 is located on the side of the second side wall 212 and the third side wall 213 away from the crimping head 110 in the first direction.

[0065] Combination Figure 6 and Figure 7 , Figure 6 and Figure 7 yes Figure 1 In two different situations of the BB cross-sectional view, the second side wall 212 and the third side wall 213 respectively form a second angle β and a third angle γ with the portion of the bearing surface 101 located outside the notch 201, the second angle β is greater than the first angle α, and the third angle γ is greater than the first angle α.

[0066] In one embodiment, the first side wall 211 extends along a second direction perpendicular to the first direction, and the second side wall 212 and the third side wall 213 both extend along the first direction.

[0067] When the screen body 20 slides into the notch 201, the screen body 20 can slide along the extension direction of the second side wall 212 and the third side wall 213, that is, the second side wall 212 and the third side wall 213 can guide the sliding of the screen body 20 in the first direction. In addition, the second angle β formed by the second side wall 212 and the third angle γ formed by the third side wall 213 are both greater than the first angle α formed by the first side wall 211. When the screen body 20 slides into the notch 201, it is not easy to deviate in the second direction, and the positioning of the screen body 20 is more accurate.

[0068] Furthermore, the second angle β and the third angle γ are both between 70° and 90°.

[0069] If the second angle β and the third angle γ are too small, when the screen 20 slides into the notch 201, the screen 20 is likely to move along the second side wall 212 or the third side wall 213, that is, when the screen 20 slides into the notch 201, it is likely to deviate in the second direction. The present application limits the second angle β and the third angle γ to a special range of 70° to 90°, so that when the screen 20 slides into the notch 201, it is unlikely to deviate in the second direction, and the positioning of the screen 20 is more accurate.

[0070] It can be understood that when the second angle β and the third angle γ are both 90°, that is, when the second side wall 212 and the third side wall 213 are both vertical side walls, the width between the second side wall 212 and the third side wall 213 is exactly the width of the screen body 20. When the screen body 20 slides into the notch 201, the screen body 20 needs to be accurately inserted between the second side wall 212 and the third side wall 213, which will cause the positioning speed of the screen body 20 to slow down. At the same time, during the sliding of the screen body 20 in the notch 201, the second side wall 212 and the third side wall 213 will also produce a certain friction on the outer wall of the screen body 20, slowing down the sliding speed of the screen body 20 in the notch 201, and the screen body 20 may also be damaged to a certain extent during the insertion of the screen body 20 into the second side wall 212 and the third side wall 213.

[0071] When the second angle β and the third angle γ are less than 90°, the width between the edges of the second side wall 212 and the third side wall 213 away from the bearing surface 101 is greater than the width of the screen body 20. Therefore, it is not necessary to accurately insert the screen body 20 between the second side wall 212 and the third side wall 213, and the tolerance for the insertion position of the screen body 20 is increased. The screen body 20 can quickly slide between the second side wall 212 and the third side wall 213. The slope formed by the second side wall 212 and the third side wall 213 can also guide the screen body 20 to automatically align to a certain extent. The second side wall 212 and the third side wall 213 are not in complete contact with the outer wall of the screen body 20, which can reduce the friction on the outer wall of the screen body 20 and facilitate the screen body 20 to quickly slide and position in the notch 201.

[0072] Furthermore, the second angle β and the third angle γ are both between 70° and 75°. 70° to 75° is the optimal range of the second angle β and the third angle γ. Within this range, the screen body 20 is not likely to deviate in the second direction when sliding into the notch 201, and the second side wall 212 and the third side wall 213 will not affect the sliding speed of the screen body 20 in the notch 201.

[0073] Optionally, the second angle β is the same as the third angle γ; or, the second angle β is different from the third angle γ. Figure 6 It shows the case where the second angle β is the same as the third angle γ, Figure 7 The second angle β and the third angle γ are different. The second angle β and the third angle γ can be the same or different. Preferably, the second angle β and the third angle γ are the same, which can further avoid the problem of the screen 20 shifting in the second direction.

[0074] See again Figure 1 and Figure 4 The opening of the notch 201 is toward the crimping head 110 in the first direction. The notch 201 has an opening, which can prevent the positioning plate 200 from occupying the area directly below the crimping head 110, ensuring that the crimping head 110 can crimp the screen body 20 after the screen body 20 is positioned.

[0075] Furthermore, the first side wall 211 , the second side wall 212 and the third side wall 213 are all planes, which of course does not exclude the possibility that the first side wall 211 , the second side wall 212 and the third side wall 213 are curved surfaces such as concave or convex surfaces.

[0076] Furthermore, in order to prevent the screen body 20 from being scratched by the edge of the first side wall 211 away from the bearing surface 101 when the screen body 20 slides along the first side wall 211 in the first direction, the edge of the first side wall 211 away from the bearing surface 101 can be chamfered with an arc to prevent the screen body 20 from being scratched, and at the same time, it can make it easier for the screen body 20 to slide along the first side wall 211. The edges of the second side wall 212 and the third side wall 213 away from the bearing surface 101 can also be chamfered with an arc.

[0077] Furthermore, the positioning plate 200 is detachably positioned on the dot screen stage 100, so that different positioning plates 200 can be easily replaced for performing dot screen detection on screen bodies 20 of different models and sizes. Specifically, one of the dot screen stage 100 and the positioning plate 200 is provided with a positioning protrusion 102, and the other is provided with a positioning hole 203. The positioning protrusion 102 and the positioning hole 203 are correspondingly plugged in and matched to limit the movement of the positioning plate 200 relative to the dot screen stage 100 in a first direction and a second direction perpendicular to the first direction. Figures 1 to 4 The figure shows the situation where the positioning protrusion 102 is arranged on the dot screen stage 100, and the positioning hole 203 is arranged on the positioning plate 200. Optionally, the positioning protrusion 102 is a cylinder, and correspondingly, the positioning hole 203 is a round hole. Through the plug-in cooperation between the cylindrical positioning protrusion 102 and the round hole-type positioning hole 203, the positioning plate 200 on the dot screen stage 100 can be quickly positioned. It can be understood that the plug-in cooperation between the round hole and the cylinder can quickly achieve plug-in alignment compared with the plug-in cooperation structure of the square hole and the square column. And there are at least two positioning protrusions 102 and positioning holes 203, and it can also be as follows Figures 1 to 4 As shown, multiple positioning plates 200 are provided along the extended plane to increase the positioning accuracy of the positioning plate 200 on the dot screen stage 100 and reduce the shaking of the positioning plate 200 on the dot screen stage 100. It can be understood that in other embodiments, the detachable positioning method of the positioning plate 200 relative to the dot screen stage 100 can also be other methods besides the positioning protrusion 102 of the present embodiment cooperating with the positioning hole 203.

[0078] The positioning plate 200 may be made of plastic, metal or other materials. Considering the cost, the positioning plate 200 is preferably made of plastic.

[0079] The thickness of the positioning plate 200 may be 5 mm, or other thickness values ​​may be used.

[0080] See again Figure 1In this embodiment, the number of the crimping joints 110 on the dot screen stage 100 and the number of the notches 201 on the positioning plate 200 are both at least two, which can be used for dot screen detection of at least two screen bodies 20. Furthermore, the number of the crimping joints 110 on the dot screen stage 100 and the number of the notches 201 on the positioning plate 200 are both at least three, which can be used for dot screen detection of at least three screen bodies 20. The crimping joints 110 on the dot screen stage 100 and the notches 201 on the positioning plate 200 are distributed along a second direction perpendicular to the first direction, which can avoid mutual influence when multiple screen bodies 20 are detected simultaneously.

[0081] See also Figure 8 , Figure 8 It is a top view of another embodiment of the dot screen fixture 10 provided by the present application. In this embodiment, the sizes of the notches 201 on the positioning plate 200 are different, and can be used for dot screen detection of screens 20 of different models and sizes. The sizes of the notches 201 on the positioning plate 200 can also be the same, and can be used for dot screen detection of screens 20 of the same model and size. When dot screen detection is required for screens 20 of different models and sizes, different positioning plates 200 can be replaced.

[0082] See also Fig. 9 , Fig. 9 It is a top view of another embodiment of the dot screen fixture 10 provided by the present application. In this embodiment, the number of positioning plates 200 on the same dot screen carrier 100 is at least two. Optionally, each positioning plate 200 is distributed in a straight line along a second direction perpendicular to the first direction. Of course, each positioning plate 200 can also be distributed in a straight line along the first direction, or distributed in a matrix along the first direction and the second direction. The size of the notch 201 of each positioning plate 200 is the same; or, the size of the notch 201 of each positioning plate 200 is different. At least two positioning plates 200 are set on the same dot screen carrier 100. Multiple positioning plates 200 can be used for the detection of at least two screen bodies 20 of the same model, and can also be used for the detection of at least two screen bodies 20 of different models, which is more flexible.

[0083] The present application also provides a screen-pointing method of the screen-pointing fixture 10, and the screen-pointing method comprises:

[0084] Step S10 : pre-positioning the positioning plate 200 on the carrying surface 101 of the dot screen stage 100 .

[0085] Step S20: placing the screen body 20 on the surface of the positioning plate 200 away from the bearing surface 101, and gradually sliding the screen body 20 into the notch 201 along the first direction from the first side wall 211 until the outer contour of the screen body 20 is aligned with the contour line 202 of the notch 201;

[0086] Step S30 : crimping the crimping head 110 to the screen body 20 .

[0087] Preferably, the screen-dotting method of the present application is used to dot the flexible screen body 20 .

[0088] The present application provides a positioning plate 200 that can be positioned on the screen dot platform 100. As long as the screen body 20 slides into the notch 201 of the positioning plate 200, the outer contour of the screen body 20 is aligned with the contour line 202 on the side of the notch 201 close to the bearing surface 101, and the positioning plate 200 is accurately positioned. The present application uses the positioning plate 200 to accurately align the position of the screen body 20 on the screen dot platform 100, thereby avoiding the problem of misalignment between the screen body 20 and the crimping joint 110, which may cause abnormal screen dot detection display or burns of the screen body 20. In addition, the screen dot fixture 10 of the present application can realize rapid positioning of the screen body 20, thereby increasing screen dot efficiency.

[0089] In addition, the third side wall 213 of the present application forms a slope structure, and the screen body 20 can more easily slide into the notch 201 along the third side wall 213, and the positioning speed of the screen body 20 is faster. In the related art, when the screen body 20 is aligned, the screen body 20 is aligned by sliding the entire surface of the screen body 20 against the bearing surface 101 of the point screen carrier 100. The friction between the screen body 20 and the bearing surface 101 is relatively large, and the sliding of the screen body 20 is relatively laborious. In the present application, the screen body 20 slides into the notch 201 along the slope formed by the third side wall 213, and a section of suspension is formed between the front end of the screen body 20 and the edge of the third side wall 213 on the side away from the bearing surface 101. Therefore, the screen body 20 does not slide against the bearing surface 101 on the entire surface, which reduces the friction between the screen body 20 and the bearing surface 101 and is also conducive to the rapid sliding of the screen body 20 to achieve positioning.
