[0033] like Figures 1 to 4 As shown in the figure, this is an embodiment of the present invention, which relates to a light guide plate oblique insertion assembly device, including a device body 10. The device body 10 includes a processing turntable 20, a positioning fixture 30, and a gripping unit 40. The upper surface of the processing turntable 20 is provided with a plurality of bearing stations 21. The bearing stations 21 are detachably connected to the positioning fixture 30 and are used to support the positioning fixture 30. The positioning fixture 30 is used to fix the plastic shell 11 to be assembled. The gripping unit 40 is used to grip the light guide plate (not shown in the figure) and insert it obliquely into the plastic shell 11 on the positioning fixture 30 at a preset tilt angle.
[0034] Specifically, the overall device, through the configuration of a processing turntable 20, a positioning fixture 30, and a gripping unit 40, enables the assembly operation of the light guide plate (not shown in the figure) being obliquely inserted into the housing 11. Compared with traditional manual assembly, this significantly improves assembly efficiency and accuracy, and achieves an automated assembly process, reducing labor costs. In this embodiment, the preset tilt angle is 45 degrees.
[0035] like Figure 1 As shown, the processing turntable 20 is a circular turntable, and the multiple bearing stations 21 are evenly distributed along the circumference of the processing turntable 20. Specifically, by designing the processing turntable 20 as a circular turntable and the multiple bearing stations 21 being evenly distributed along its circumference, this design allows each bearing station 21 to smoothly and accurately switch to the designated position when the processing turntable 20 rotates, ensuring the stability of the positioning fixture 30 supporting the housing 11, and improving the stability and continuity of the overall assembly.
[0036] like Figure 1As shown, the bottom of the machining turntable 20 is connected to an indexing drive mechanism 22, which drives the machining turntable 20 to rotate intermittently to switch the positioning fixtures 30 on different bearing positions 21 to below the gripping unit 40. Specifically, the indexing drive mechanism 22 drives the machining turntable 20 to rotate intermittently, which can precisely control the timing of the positioning fixtures 30 switching to below the gripping unit 40, realizing assembly work according to the rhythm, facilitating collaborative operation with other production links, and improving the controllability of the production rhythm. In this embodiment, the indexing drive mechanism 22 is an existing drive mechanism, and its structure and model will not be described in detail.
[0037] like Figure 2 As shown, the positioning fixture 30 includes a fixture body 31 and a plurality of positioning components 50. The surface of the fixture body 31 is provided with through holes 32 arranged in an array. The plurality of positioning components 50 are arranged along the edge of the fixture body 31. Each positioning component 50 includes an extension piece 51 and a fastening screw 52, the fastening screw 52 passing through the extension piece 51 and detachably connected to the through hole 32. Specifically, by arranging the plurality of positioning components 50 along the edge of the fixture body 31 and by detachably connecting the fastening screw 52 to the through hole 32, the position of the positioning components 50 can be flexibly adjusted to adapt to the fixing requirements of different sized housings 11, thus improving the versatility of the positioning fixture 30.
[0038] like Figure 2 As shown, the extension piece 51 has an elongated hole 53 in the center, and the elongated hole 53 is connected to the fastening screw 52. Specifically, the connection between the elongated hole 53 and the fastening screw 52 allows the positioning component 50 to be finely adjusted within a certain range, further enhancing its adaptability to different sizes of the housing 11 and improving positioning accuracy.
[0039] like Figure 2 As shown, the number of positioning components 50 is set to four sets, which are symmetrically distributed circumferentially along the fixture body. Two sets of positioning components 50 are evenly arranged along the length direction of the fixture body 31, and the other two sets are arranged along the width direction. Specifically, the four sets of positioning components 50 are symmetrically distributed circumferentially along the fixture body, with two sets arranged along the length direction and two sets along the width direction. This enables stable positioning of the housing 11 from multiple directions, ensuring that the housing 11 will not shift or shake during assembly, thus improving assembly quality.
[0040] like Figure 3As shown, the gripping unit 40 includes a vertical drive module 60, a rotary drive module 41, and a gripping module 70. The vertical drive module 60 drives the rotary drive module 41 to perform lifting and lowering movements. The rotary drive module 41 is fixedly connected to the output end of the vertical drive module 60 and drives the gripping module 70 to rotate to form a preset tilt angle. The gripping module 70 is installed on the output end of the rotary drive module 41 and is used to adsorb the light guide plate (not shown in the figure). Specifically, through the coordinated work of the vertical drive module 60, the rotary drive module 41, and the gripping module 70, the gripping unit 40 can precisely control the gripping, lifting, and tilting angle of the light guide plate (not shown in the figure), ensuring that the light guide plate (not shown in the figure) can be accurately inserted into the housing 11 at a preset tilt angle, thereby improving the accuracy and reliability of assembly.
[0041] like Figure 3 As shown, the vertical drive module 60 includes a vertical linear guide rail 61, a lifting slider 62 that slides with the vertical linear guide rail 61, and a vertical cylinder 63 that drives the lifting slider 62. The rotary drive module 41 is a rotary cylinder or a servo rotary motor, with its fixed end connected to the lifting slider 62 and its output end fixedly connected to the gripping mechanism. Specifically, the vertical drive module 60 uses a vertical linear guide rail 61, a lifting slider 62, and a vertical cylinder 63, while the rotary drive module 41 uses a rotary cylinder or a servo rotary motor. This combination of mature drive components has the advantages of simple structure, stable operation, and high control precision, ensuring the reliability and efficiency of the gripping unit 40.
[0042] like Figure 3 As shown, the gripping module 70 includes an X-shaped adsorption plate 71 and several adsorption disks 72. An external air source (not shown) is connected to the X-shaped adsorption plate 71. The several adsorption disks 72 are equidistantly connected to the bottom of the X-shaped adsorption plate 71. Specifically, the gripping module 70 uses an X-shaped adsorption plate with an external air source (not shown) and multiple adsorption disks 72 equidistantly connected to the bottom, which can uniformly adsorb the light guide plate (not shown), ensuring that the light guide plate (not shown) is subjected to uniform force during gripping and moving, preventing deformation and improving the gripping stability of the light guide plate (not shown). In this embodiment, the air source (not shown) can be a vacuum pump.
[0043] like Figure 4As shown, the bottom of the housing 11 has several positioning grooves 12 along its length. The positioning grooves 12 are connected to the top of the fastening screws 52. The side of the housing 11 facing away from the positioning grooves 12 abuts against the corresponding fastening screws 52 to support one side of the housing 11. Specifically, the positioning grooves 12 at the bottom of the housing 11 are connected to the top of the fastening screws 52, and one side of the housing 11 abuts against the fastening screws 52 to support the housing 11. This connection method further stabilizes the position of the housing 11 on the positioning fixture 30, ensuring the stability of the housing 11 when the light guide plate (not shown in the figure) is inserted at an angle.
[0044] The working principle of this utility model is as follows:
[0045] During operation, the indexing drive mechanism 22 drives the processing turntable 20 to rotate intermittently, sequentially switching the positioning fixture 30 carrying the plastic shell 11 to below the gripping unit 40. The positioning fixture 30, through the positioning component 50 on the fixture body 31, uses the fastening screw 52 to engage with the positioning groove 12 at the bottom of the plastic shell 11 and abut against one side of the plastic shell 11 to stably fix the plastic shell 11. The vertical drive module 60 in the gripping unit 40 drives the rotary drive module 41 to move to the appropriate position, and the gripping module 70 connects to an external air source (not shown in the figure) through the X-shaped adsorption plate, using the adsorption plate 72 at the bottom to adsorb the light guide plate (not shown in the figure). Then, the rotary drive module 41 drives the gripping module 70 to rotate to a preset tilt angle of 45°. The vertical drive module 60 then drives the rotary drive module 41 and the gripping module 70 to descend, inserting the light guide plate (not shown) at a preset tilt angle of 45° into the housing 11 on the positioning fixture 30. After insertion, the rotary drive module 41 rotates again, changing the light guide plate (not shown) from an angled state to a state parallel to the housing 11, and performs parallel pressing on the light guide plate (not shown) to ensure a tight fit between the light guide plate (not shown) and the housing 11. Afterward, the processing turntable 20 rotates again, switching to the next positioning fixture 30 carrying the housing 11 below the gripping unit 40, and repeating the above operation to achieve continuous automated assembly.
[0046] This utility model, through multifaceted structural design and the coordination of drive components, has many beneficial effects, such as improving assembly efficiency, enhancing assembly accuracy, increasing the versatility of the positioning fixture 30, ensuring the stability of the housing 11 and the light guide plate (not shown in the figure) during the assembly process, and ensuring reliable and efficient equipment operation. It can well meet the needs of industrial production for the oblique insertion assembly of the light guide plate (not shown in the figure) and the housing 11, and helps to improve the production quality and efficiency of related products and reduce production costs.
[0047] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
