Description

Technical Field

[0001] This utility model relates to the field of processing fixtures, and in particular to a dispensing fixture for the inner frame of a display module. Background Technology

[0002] As the internal frame of the display module, it is responsible for connecting the PCB and various connectors, as well as fixing the display modules. This inner frame structure is mainly composed of metal (or hard plastic) frame plates of various sizes, which are welded or directly cut into one piece. Before fixing the PCB and various components, glue needs to be applied.

[0003] Current methods involve manually marking and then applying glue, or using specialized fixtures for fixation before application. However, manual glue application inevitably suffers from inconsistent quality and missed spots, and is inefficient. Furthermore, existing fixtures have complex structures and fixation methods, and setting up the glue-applying robot is cumbersome.

[0004] In view of this, this technical solution proposes an inner frame dispensing fixture for display modules. It adopts a simple fixed limiting structure, which can not only limit the frame plates of various widths in multiple directions, but also is equipped with a dispensing head that can move in multiple axes. It can perform manual dispensing or automatic dispensing after being connected to automated equipment, and has strong adaptability. Utility Model Content

[0005] The present invention aims to at least partially solve one of the technical problems in the related art. Therefore, the main objective of this invention is to provide a dispensing fixture for the inner frame of a display module, aiming to solve the problems of complex dispensing structures, low efficiency of manual dispensing, and poor adaptability in the existing display module inner frame.

[0006] To achieve the above objectives, this utility model provides a dispensing fixture for the inner frame of a display module, comprising a fixture body consisting of a base, a platform, and a multi-axis dispensing assembly located above the platform.

[0007] The platform is provided with a rectangular carrier plate for placing products, and through holes are evenly distributed in four directions on the carrier plate. Clamping pieces are provided in the through holes, and a stop block is provided on the side near the clamping pieces.

[0008] The multi-axis dispensing assembly includes Y-axis slide rails disposed on both sides of the platform, Y-axis slide blocks disposed on the Y-axis slide rails, the tops of the Y-axis slide blocks on both sides being connected to the X-axis slide rails, X-axis slide blocks disposed on the X-axis slide rails, and a dispensing head that can be raised and lowered disposed on one side of the bottom of the X-axis slide block.

[0009] As a further embodiment of this utility model, the dispensing head is detachably and replaceably connected to the X-axis slide via a mounting base. The mounting base is L-shaped and has a lifting device on its back for driving the dispensing head to rise and fall.

[0010] As a further improvement of this utility model, the mounting base is also provided with an air blowing device for quickly drying the colloid and blowing out debris.

[0011] As a further embodiment of this invention, the air blowing device is a rotating nozzle connected to an air blowing pipe.

[0012] As a further embodiment of this utility model, the clip is a metal spring structure with spring-loaded properties.

[0013] As a further embodiment of this utility model, the carrier plate is also provided with a positioning part for cooperating with the platform at the bottom. The positioning part is concave and is stacked and limited by the concavity of the corresponding positions of the carrier plate and the platform.

[0014] The beneficial effects of this utility model are as follows:

[0015] This technical solution addresses the problems of low efficiency, uneven glue application, poor fixture compatibility, and complex structure in traditional display module inner frame dispensing processes. Existing technologies rely on manual marking for dispensing, which is prone to missed spots and glue overflow. Furthermore, the fixtures are difficult to adapt to different frame sizes, resulting in time-consuming adjustments. This solution utilizes a dual-limiting design with four-way through-holes on a rectangular carrier plate incorporating metal spring clips and stops. The clips automatically conform to the edges of frame panels of different sizes due to their spring-loaded properties, while the stops restrict displacement, preventing surface scratches and ensuring stable clamping, significantly improving compatibility and positioning efficiency. The multi-axis dispensing assembly uses Y-axis slide rails on both sides to drive the slide block, which in turn links the X-axis slide rail and slide block, allowing the dispensing head to move freely in the plane. Combined with a lifting device, the height can be precisely adjusted to ensure uniform glue coverage of all areas of the inner frame, greatly improving dispensing accuracy and path flexibility. The L-shaped mounting base supports quick disassembly and replacement of the dispensing head, adapting to diverse dispensing needs. It also integrates a rotary air nozzle to accelerate glue drying and remove debris from the work area, reducing rework rates. The carrier plate and stage are stacked and limited by a recessed positioning part, achieving rapid and accurate alignment and avoiding assembly misalignment. The overall structure simplifies the debugging process of traditional complex fixtures, improving production efficiency and finished product yield while reducing manual intervention and equipment maintenance costs. It is suitable for automated or semi-automated dispensing scenarios for multi-specification products. Attached Figure Description

[0023] as follows:

[0024] Please see the appendix Figure 1-5 ,

[0025] The main structure includes a fixture body (1) consisting of a base (10), a platform (11), and a multi-axis dispensing assembly (13) located above the platform (11). The platform (11) is provided with a carrier plate (12) for placing products. The carrier plate (12) is rectangular and has through holes (120) evenly distributed in four directions. Clamping pieces (121) are provided in the through holes (120). A stop (122) is provided on one side. The multi-axis dispensing assembly (13) includes a Y-axis slide rail (135) provided on both sides of the platform (11). A Y-axis slide block (134) is provided on the Y-axis slide rail (135). The top of the Y-axis slide blocks (134) on both sides is connected to the X-axis slide rail (130). An X-axis slide block (131) is provided on the X-axis slide rail (130). A dispensing head (133) that can be raised and lowered is provided on one side of the bottom of the X-axis slide block (131).

[0026] The working principle is as follows:

[0027] This technical solution effectively solves the problems of low efficiency, poor accuracy, and insufficient adaptability in the traditional dispensing process for the inner frame of display modules. In existing technologies, manual dispensing relies on manual marking, which is prone to missed spots or uneven glue application, and the fixing fixture has a complex structure that is difficult to adapt to frame plates of different sizes.

[0028] This solution uses a rectangular carrier plate (12) combined with a four-way through-hole (120) structure. A spring-loaded metal clip (121) with rebound properties is installed inside the through-hole (120). A stop (122) is added on the side closest to the clip (121) to form a double limit. The clip (121) and stop (122) are distributed on two opposite sides of the carrier plate (12), with at least one pair of opposite sides having two or more limit structures to ensure the product is securely clamped on the carrier plate (12) and cannot shift, making it particularly suitable for rapid positioning of various frame sizes. The multi-axis dispensing assembly (13) drives the Y-axis slide (134) to move via two Y-axis slide rails (135), enabling flexible movement of the X-axis slide rail (130) and slide (131) within a plane. Combined with a liftable dispensing head (133), it can accurately cover all areas of the inner frame, significantly improving the freedom and consistency of the dispensing path. The dispensing head (133) adopts a detachable L-shaped mounting base (132) design, which facilitates quick replacement of different models of dispensing heads (133). It also integrates a lifting device (136) and a rotary air nozzle blowing device (137), which can adjust the dispensing height to meet different glue volume requirements, and can dry the glue and remove debris from the work area in real time, further shortening the production cycle. The carrier plate (12) and the stage (11) are stacked and limited by the recessed positioning part (123) to ensure assembly accuracy and repeatability.

[0029] This technical solution simplifies the fixture structure while achieving efficient, high-precision, and highly adaptable dispensing operations, significantly reducing manual intervention and equipment debugging costs.

[0030] The assembly and disassembly process can be,

[0031] During assembly, first fix the base (10) to the platform (11), ensuring that the recessed part of the positioning part (123) on the platform (11) is aligned with the corresponding position of the base (10). Then, install the Y-axis slide rails (135) on both sides of the platform (11) and insert the Y-axis slide block (134) into the slide rails (135). Subsequently, connect the X-axis slide rail (130) laterally to the top of the Y-axis slide blocks (134) on both sides and install the X-axis slide block (131). Move to the X-axis slide rail (130), then fix the L-shaped mounting base (132) to the bottom of the X-axis slide (131) in a detachable manner, and connect the dispensing head (133) and the lifting device (136). Finally, insert the metal spring clips (121) into the four directional through holes (120) of the carrier plate (12), and install the stop block (122) next to the clip (121) to complete the stacking limit of the carrier plate (12) and the platform (11).

[0032] Disassembly is performed in reverse order. First, remove the clips (121) and the stop (122) on the carrier plate (12), separate the carrier plate (12) from the platform (11), loosen the connection between the mounting base (132) and the X-axis slide (131), remove the dispensing head (133), and then remove the X-axis slide (131), X-axis slide rail (130), and both Y-axis slides (134) in sequence. Finally, release the fixation between the Y-axis slide rail (135) and the platform (11), and separate the base (10) from the platform (11).

[0033] Reference Appendix Figure 3 , 5 In a preferred embodiment of this utility model, the dispensing head (133) is detachably and replaceably connected to the X-axis slide (131) through the mounting base (132). The mounting base (132) is L-shaped and has a lifting device (136) on its back for driving the dispensing head (133) to rise and fall.

[0034] The dispensing head (133) is connected to the X-axis slide (131) via the L-shaped mounting bracket (132), enabling quick disassembly and replacement of dispensing heads (133) of different specifications, facilitating adaptation to diverse dispensing needs. The lifting device (136) on the back of the mounting bracket (132) can precisely adjust the height of the dispensing head (133), ensuring consistent contact pressure between the adhesive and the inner frame, avoiding uneven adhesive application or overflow, and improving operational stability and flexibility.

[0035] Reference Appendix Figure 5 In a preferred embodiment of this utility model, the mounting base (132) is further provided with an air blowing device (137) for quickly drying the colloid and blowing out debris. The air blowing device (137) is a rotating nozzle connected to an air blowing pipe.

[0036] The air blowing device (137) added to the mounting base (132) in this technical solution continuously blows air through the rotating air nozzle, which accelerates the drying of the colloid, shortens the production time, and blows away the dust or debris in the working area in time, so as to avoid the adhesion of impurities and affect the dispensing quality.

[0037] Reference Appendix Figure 2 In a preferred embodiment of this utility model, the clip (121) is a metal spring structure with spring-loaded properties.

[0038] The metal spring clip (121) can automatically fit the edge of the frame plate of different sizes, firmly clamp the product and avoid scratching the surface. It can adapt to slight deformation through elastic adjustment to ensure the stability and reliability of the clamping force during long-term use.

[0039] Reference Appendix Figure 2 In a preferred embodiment of this utility model, the carrier plate (12) is further provided with a positioning part (123) for cooperating with the bottom platform (11). The positioning part (123) is concave and is stacked and limited by the concavity of the corresponding positions of the carrier plate (12) and the platform (11).

[0040] The use of convex and concave mating achieves rapid and accurate alignment, ensuring that the carrier plate (12) is completely aligned with the stage (11) each time it is placed, avoiding offset or misalignment, simplifying assembly steps, shortening adjustment time, and improving repeatability positioning accuracy.
