Description

Technical Field

[0001] This utility model relates to the field of display module technology, specifically to an anti-offset fixing structure for an optical cover plate with graduations in a display module. Background Technology

[0002] As a core component of various electronic devices (such as smartphones, tablets, automotive displays, industrial control screens, etc.), the optical cover plate of the display module not only protects the display panel but also directly affects key performance aspects such as display clarity and light transmittance. During the production and assembly of display modules, precise alignment between the optical cover plate and the main body of the display module (including the display panel, backlight assembly, driver circuit board, etc.) is a crucial step in ensuring product quality.

[0003] Traditional fixing methods lack intuitive positioning references, and operators rely solely on experience for alignment. This can easily lead to optical cover plate misalignment due to visual errors, resulting in obstruction of the display area edges and misalignment of the display image, affecting the product's appearance and performance.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a scaled anti-displacement fixing structure for the optical cover of the display module. Utility Model Content

[0005] The purpose of this invention is to provide a scaled anti-offset fixing structure for the optical cover plate of a display module, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a graduated anti-offset fixing structure for an optical cover plate of a display module, comprising a support assembly and a fixing frame. The support assembly includes a support platform and a placement cavity, with the placement cavity located on the top of the support platform. The fixing frame is fixed to the right side of the support platform surface, and a servo motor is mounted on the top of the fixing frame. The output end of the servo motor is connected to a bidirectional lead screw, and a lead screw nut is connected to the outside of the bidirectional lead screw. A mounting block is connected to the outside of the lead screw nut. A crossbeam is connected to the upper mounting block, and a second crossbeam is connected to the lower mounting block. A servo motor 2 is installed on the top left side of the crossbeam 1, and the output end of the servo motor 2 is connected to a drive shaft. The other end of the drive shaft is connected to a transmission shaft via a telescopic rod, and a bevel gear 2 is installed at the end of the transmission shaft. A bevel gear 1 is provided on the outside of the drive shaft, and bevel gear 3 and bevel gear 4 are respectively meshed on the outside of bevel gear 1 and bevel gear 2. The right ends of bevel gear 3 and bevel gear 4 are respectively connected to a double-acting lead screw 2 and a double-acting lead screw 3, and a lead screw nut 2 is connected to both double-acting lead screw 2 and double-acting lead screw 3. A vertical plate is connected to the outside of the lead screw nut 2. The surface of the support platform is provided with a first scale line and a second scale line.

[0007] Furthermore, the support assembly also includes a material placement seat, and the material placement seat is installed inside the placement cavity.

[0008] Furthermore, the drive shaft is vertically inserted into the bearing at the bottom left opening of the first crossbeam, and the transmission shaft is vertically inserted into the bearing at the top left opening of the second crossbeam, with the first crossbeam and the second crossbeam being parallel to each other.

[0009] Furthermore, the ratio of the number of lead screw nut one, lead screw nut two, and vertical plate is 1:2:2, and there are four vertical plates. The horizontal frame one and the vertical plates are perpendicular to each other.

[0010] Furthermore, the first and second bidirectional lead screws are perpendicular to each other, and the third and second bidirectional lead screws are parallel to each other.

[0011] Furthermore, the end of the bidirectional lead screw two away from the bevel gear three is rotatably connected to the cross frame one, and the end of the bidirectional lead screw three away from the bevel gear four is rotatably connected to the cross frame two.

[0012] Furthermore, the first scale line is distributed along the length direction of the support platform, and the second scale line is distributed along the width direction of the support platform, with two of each scale line.

[0013] This utility model provides a graduated anti-displacement fixing structure for the optical cover plate of a display module, which has the following advantages:

[0014] 1. This utility model uses a servo motor to drive a bidirectional lead screw, which can adjust the vertical spacing of the first and second horizontal frames. This, combined with the intuitive positioning of the second scale line, adapts to the width of the optical cover plate, preventing compression of the optical cover plate. The second servo motor drives the drive shaft, telescopic rod, and transmission shaft, which can adjust the horizontal spacing of the four vertical plates. This, combined with the intuitive positioning of the first scale line, adapts to the length of the optical cover plate. By coordinating horizontal and vertical movements, the displacement of the optical cover plate is limited, resulting in good anti-deviation effect and reduced production errors.

[0015] 2. The dimensions of the material placement base of this utility model are perfectly matched with the display module body. After the display module body is placed in, it fits tightly with the placement cavity, quickly restricts horizontal displacement, and directly completes the initial positioning, reducing the amount of correction for subsequent alignment. Moreover, the depth of the placement cavity is greater than the height of the material placement base, and the top edge of the display module body is higher than the cavity wall, leaving unobstructed space for the optical cover plate to cover, avoiding collision and displacement. At the same time, it is convenient to directly pinch the edge to remove it after assembly without auxiliary tools. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 3As shown, a graduated anti-offset fixing structure for an optical cover plate of a display module includes a support assembly 1 and a fixing frame 2. The fixing frame 2 is fixed to the right side of the surface of the support platform 101, and a servo motor 3 is mounted on the top of the fixing frame 2. The output end of the servo motor 3 is connected to a bidirectional lead screw 4, and a lead screw nut 5 is connected to the outside of the bidirectional lead screw 4. A mounting block 6 is connected to the outside of the lead screw nut 5. A crossbeam 7 is connected to the upper mounting block 6, and a crossbeam 8 is connected to the lower mounting block 6. The top left of the crossbeam 7... A servo motor 2 9 is mounted on the side, and the output end of the servo motor 2 9 is connected to a drive shaft 10. The other end of the drive shaft 10 is connected to a transmission shaft 12 via a telescopic rod 11, and a bevel gear 2 14 is mounted on the end of the transmission shaft 12. A bevel gear 13 is provided on the outside of the drive shaft 10, and bevel gear 13 and bevel gear 2 14 are respectively meshed with bevel gear 3 15 and bevel gear 4 16. The right ends of bevel gear 3 15 and bevel gear 4 16 are respectively connected to a double-acting lead screw 2 17 and a double-acting lead screw 3 18, and the double-acting lead screw 2 17... Both the first and second lead screws 18 are connected to lead screw nuts 29. Vertical plates 20 are connected to the outside of the lead screw nuts 219. The surface of the support platform 101 has a first scale line 21 and a second scale line 22. The drive shaft 10 is vertically inserted into the bearing at the bottom left opening of the cross frame 7, and the transmission shaft 12 is vertically inserted into the bearing at the top left opening of the cross frame 28. The cross frame 7 and cross frame 28 are parallel to each other. The ratio of the number of lead screw nuts 15, lead screw nuts 219, and vertical plates 20 is 1:2:2, and four vertical plates 20 are provided. The first frame 7 and the vertical plate 20 are perpendicular to each other. The first double-acting screw 4 and the second double-acting screw 17 are perpendicular to each other, and the second double-acting screw 17 and the third double-acting screw 18 are parallel to each other. The end of the second double-acting screw 17 away from the bevel gear 15 is rotatably connected to the first horizontal frame 7. The end of the third double-acting screw 18 away from the bevel gear 16 is rotatably connected to the second horizontal frame 8. The first scale line 21 is distributed along the length direction of the support platform 101, and the second scale line 22 is distributed along the width direction of the support platform 101. There are two of each of the first scale line 21 and the second scale line 22.

[0022] The specific operation is as follows: Servo motor 3 drives bidirectional lead screw 4, which can drive crossbeam 7 and crossbeam 8 to adjust the vertical spacing. This, combined with the intuitive positioning of the second scale line 22, adapts to the width of the optical cover plate and avoids squeezing the optical cover plate. Servo motor 9 drives drive shaft 10, telescopic rod 11, and transmission shaft 12, which can drive the four vertical plates 20 to adjust the horizontal spacing. This, combined with the intuitive positioning of the first scale line 21, adapts to the length of the optical cover plate. By coordinating horizontal and vertical movements, the displacement of the optical cover plate is limited, resulting in good anti-displacement effect and reducing production errors.

[0023] like Figure 2As shown, the support assembly 1 includes a support platform 101 and a placement cavity 102, and the support platform 101 is provided with a placement cavity 102 on its top. The support assembly 1 also includes a material placement seat 103, and the material placement seat 103 is installed in the placement cavity 102.

[0024] The specific operation is as follows: the size of the material holder 103 is perfectly matched with the display module body. After the display module body is placed in, it fits tightly with the placement cavity 102, quickly restricting horizontal displacement and directly completing the initial positioning, reducing the amount of correction for subsequent alignment. Moreover, the depth of the placement cavity 102 is greater than the height of the material holder 103, and the top edge of the display module body is higher than the cavity wall, reserving unobstructed space for the optical cover plate to cover, avoiding collision and displacement. At the same time, it is convenient to directly pinch the edge to remove it after assembly without auxiliary tools.

[0025] In summary, the graduated anti-displacement fixing structure for the optical cover of the display module allows the operator to first place the display module body to be assembled on the placement seat 103. The length and width of the placement seat 103 inside the cavity are perfectly matched with the display module body. After the display module body is placed in, its side wall fits tightly against the inner wall of the placement seat 103, which can quickly limit the horizontal displacement of the module and directly complete the initial positioning. At the same time, the depth of the placement cavity 102 is greater than the height of the placement seat 103, and the top edge of the display module body is higher than the cavity wall. This not only makes it convenient for the operator to directly pinch the edge of the module to remove it after subsequent assembly, but also leaves unobstructed fitting space for the optical cover to cover it.

[0026] The operator then places the optical cover plate over the main body of the display module. Precise alignment is not required. The servo motor 3 is then started, which drives the bidirectional lead screw 4 to rotate. This causes the two sets of lead screw nuts 5 to drive the crossbeams 7 and 8 to move in opposite directions through the upper and lower mounting blocks 6, gradually reducing the vertical distance between the crossbeams 7 and 8. At the same time, the operator observes the second scale line 22 and adjusts the vertical distance between the crossbeams 7 and 8 to match the width of the optical cover plate. The servo motor 3 is then paused to avoid squeezing the optical cover plate.

[0027] Next, servo motor 29 is started, which drives drive shaft 10, telescopic rod 11, transmission shaft 12, bevel gear 13, and bevel gear 24 to rotate. Bevel gear 13 and bevel gear 2 mesh with bevel gear 3 15 and bevel gear 4 16 respectively, driving double-acting lead screw 2 17 and double-acting lead screw 3 18 to rotate. This causes lead screw nut 2 19 to drive vertical plate 20 to move towards each other in the horizontal direction, gradually reducing the horizontal distance between vertical plates 20. At the same time, the operator observes the first scale line 21. When the horizontal distance between vertical plates 20 is adjusted to match the length of the optical cover plate, servo motor 29 is paused.

[0028] At this time, the four vertical plates 20 restrict the lateral displacement of the optical cover plate, and the horizontal frame 7 and the horizontal frame 8 restrict the vertical displacement of the optical cover plate. The optical cover plate is positioned in the center area of ​​the material placement seat 103, completing the alignment and anti-offset fixation with the main body of the display module.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
