Technical Field

[0001] This utility model relates to the technical field of LCM module assembly equipment, specifically to an LCD and backlight lamp assembly based on an LCM module. Background Technology

[0002] LCM modules, also known as liquid crystal display modules, are core components of various electronic devices. Their assembly quality directly affects the display effect. Among them, the assembly of LCD and backlight is a key step, where LED beads on the FPC are pressed into the backlight slots to form a complete display system.

[0003] In the current technology, there is no mature, stable and efficient backlight assembly equipment without light source in the market. Almost all assembly is done by workers by hand. There is no equipment that is compatible with both backlight and backlight assembly products with and without light source. The flip assembly uses mechanical correction, which is slow. The use of mechanical correction to align the position of the LCD and the backlight leads to misalignment of the LED beads and the LED slot, resulting in a high defect rate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an LCD and backlight lamp assembly based on an LCM module, which has the advantages of high efficiency, automation, and strong compatibility, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an LCD and backlight pressing assembly based on an LCM module, comprising a vision alignment module and an assembly module. The vision alignment module consists of two sets of industrial cameras mounted on an external mounting frame, an external planar open-aperture light source, and an image processing unit. The assembly module includes a robotic arm, a backlight support platform, and an LCD support platform. A backlight body is placed on the upper surface of the backlight support platform, and an LCD body is placed on the upper surface of the LCD support platform. The output end of the robotic arm is equipped with a pressure strip and a suction cup. In use, the external robotic arm places the backlight body on the upper surface of the backlight support platform and the LCD body on the upper surface of the LCD support platform. When pressing down, the robotic arm presses down through the pressure strip to press the FPC on the LCD and the backlight body.

[0006] Furthermore, an FPC is provided on the upper surface of the LCD body, and the FPC corresponds to the slot opened on the surface of the backlight body.

[0007] The above method completes the lamp pressing operation between the LCD body and the backlight body by pressing the LEDs on the FPC into the lamp slot of the backlight body.

[0008] Furthermore, the assembly module also includes a longitudinal moving component, a lateral moving component, and a vertical moving component mounted on an external platform. The longitudinal moving component is connected to the external platform, the lateral moving component is mounted on the upper surface of the longitudinal moving component, the vertical moving component is mounted on the top of the lateral moving component, and the side of the vertical moving component is connected to the robotic arm.

[0009] The above scheme utilizes longitudinal, lateral, and vertical movement components to drive the robotic arm to achieve three-dimensional spatial position adjustment.

[0010] Furthermore, a movable adjustment component is provided below the backlight carrying platform, and the output end of the movable adjustment component is connected to the backlight carrying platform.

[0011] The above scheme uses a movable adjustment component to move the backlight carrier platform, allowing the backlight carrier platform to bring the backlight body closer to the LCD body on the LCD carrier platform.

[0012] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0013] This is an LCD and backlight pressing assembly based on an LCM module. By visually photographing the feature points of the backlight body and the LCD body, the positions of the backlight body and the LCD body are corrected.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of an LCD and backlight pressing assembly based on an LCM module includes a vision alignment module 1 and an assembly module 2. The vision alignment module 1 consists of two sets of industrial cameras 101 mounted on an external mounting frame, an external planar open-aperture light source, and an image processing unit. The assembly module 2 includes a robotic arm 201, a backlight support platform 202, and an LCD support platform 203. A backlight body 204 is placed on the upper surface of the backlight support platform 202, and an LCD body 205 is placed on the upper surface of the LCD support platform 203. A pressure bar 206 and a suction cup 207 are installed at the output end of the robotic arm 201. In use, the external robotic arm 201 places the backlight body 204 on the upper surface of the backlight support platform 202 and the LCD body 205 on the upper surface of the LCD support platform 203. When pressing down, the robotic arm 201 presses down through the pressure bar 206 to press the FPC 208 and the backlight body 204 together.

[0026] Please see Figure 2 , Figure 3 and Figure 4 Please see Figure 1 , Figure 2 and Figure 3 An FPC208 is provided on the upper surface of the LCD body 205. The FPC208 corresponds to the slot opened on the surface of the backlight body 204. By pressing the LEDs on the FPC208 into the LED slot of the backlight body 204, the LED pressing operation between the LCD body 205 and the backlight body 204 is completed.

[0027] Please see Figure 2 , Figure 3 and Figure 5 Assembly module 2 also includes a longitudinal moving component 209, a lateral moving component 210, and a vertical moving component 211 installed on an external platform. The longitudinal moving component 209 is connected to the external platform, the lateral moving component 210 is installed on the upper surface of the longitudinal moving component 209, the vertical moving component 211 is installed on the top of the lateral moving component 210, and the side of the vertical moving component 211 is connected to the robotic arm 201. The longitudinal moving component 209, the lateral moving component 210, and the vertical moving component 211 can drive the robotic arm 201 to achieve three-dimensional spatial position adjustment.

[0028] Please see Figure 2 , Figure 3 and Figure 6 A movable adjustment component 3 is provided below the backlight carrier platform 202. The output end of the movable adjustment component 3 is connected to the backlight carrier platform 202. The movable adjustment component 3 drives the backlight carrier platform 202 to move, so that the backlight carrier platform 202, along with the backlight body 204, moves closer to the LCD body 205 on the LCD carrier platform 203.

[0029] It should be noted that before use, ensure that the industrial camera 101 is directly above the LCD support platform 203 and the backlight support platform 202. Depending on whether the product type has no light source or a light source, select the corresponding mode on the external control system.

[0030] The working principle of the above embodiment is as follows: First, the backlight body 204 is sent to the backlight support platform 202 by the robot arm, and the LCD body 205 is placed on the LCD support platform 203 by the robot arm. The two are initially on the same horizontal plane. The industrial camera 101 captures the feature points of the backlight body 204 and the features of the LCD body 205 respectively. The image processing unit calculates the X / Y / D axis deviation of the two and corrects the position of the backlight body 204 and the LCD body 205.

[0031] Next, the lamp pressing operation is performed. When FPC208 needs to be folded, LCD support platform 203 drives LCD body 205 to descend 5-10mm vertically. Backlight body 204, driven by backlight support platform 202, moves to the position above LCD body 205 where FPC208 is flipped. LCD support platform 203 rises vertically, with a height 5-10mm higher than backlight body 204. At this point, FPC208 is bent. Then, backlight body 204 moves to directly below the lamp beads of FPC208. LCD support platform 203 moves to the lamp pressing position. When robotic arm 201 picks up the material, the pressing block at the output end of robotic arm 201 will press the lamp on FPC208 into the lamp slot of backlight body 204, completing the lamp pressing operation.

[0032] FPC208 does not require folding: LCD support platform 203 drives LCD body 205 to rise 5-10mm in the vertical direction, backlight body 204 moves to below FPC208 lamp beads, LCD body 205 moves in the vertical direction to lamp pressing height, when robotic arm 201 picks up the material, the pressing block at the output end of robotic arm 201 will press the lamp on FPC208 into the lamp slot of backlight body 204, completing the lamp pressing operation.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
