Description

Technical Field

[0001] This utility model relates to the technical field of liquid crystal module processing equipment, and in particular to an automatic alignment and bonding equipment for liquid crystal modules. Background Technology

[0002] As a core component of display devices, the precise alignment and bonding of various structural layers (such as the LCD panel, backlight layer, and polarizer) during the production process of LCD modules is crucial for ensuring display quality and product yield. Automatic alignment and bonding equipment, as an important piece of equipment on the LCD module production line, is responsible for quickly and stably aligning and bonding different structural layers according to preset precision, directly impacting the production efficiency and product quality of LCD modules. If the alignment deviation exceeds the allowable range, it will not only lead to defects in the display image (such as image retention, light leakage, and uneven display), but may also damage components and increase production costs.

[0003] Currently, the traditional method for bonding LCD modules relies heavily on manual operation using a simple control panel: the LCD module is temporarily fixed by placing it in a control panel with a groove of a fixed size, and then the panel to be bonded is positioned against the edge of the groove to complete the bonding. However, this method has significant limitations: when adapting to LCD modules of different sizes, a control panel of the corresponding size must be replaced. This is not only cumbersome and time-consuming, but also leads to decreased production efficiency due to frequent equipment changes. Furthermore, it is difficult to meet the flexible production needs of diverse products, resulting in poor applicability. Utility Model Content

[0004] The main objective of this invention is to provide an automatic alignment and bonding device for LCD modules, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic alignment and bonding device for a liquid crystal module, including an operation panel, a limit bar is provided on the front left side of the operation panel, a plurality of mounting holes are provided at equal intervals on the upper part of the operation panel, and a plurality of limiting mechanisms are provided on the upper part of the operation panel, the limiting mechanisms being connected to the mounting holes;

[0006] The limiting mechanism includes a connecting plate, a first connecting seat, a limiting rod, a baffle, a second connecting seat, a worm gear and a support frame, a worm, a threaded rod, and a knob. The lower part of the connecting seat is fixedly connected to the left and right sides of the upper part of the connecting plate. The outer periphery of the limiting rod is slidably connected to the inside of the first connecting seat. The front end of the first connecting seat is fixedly connected to the lower left and right sides of the baffle. The lower part of the second connecting seat is fixedly connected to the middle of the upper part of the connecting plate. The outer periphery of the threaded rod is slidably connected to the inside of the second connecting seat. The front end of the threaded rod is fixedly connected to the middle side of the upper part of the baffle. The front side of the worm gear is rotatably connected to the rear side of the second connecting seat. The outer periphery of the threaded rod is threadedly connected to the middle of the worm gear. The support frame is installed on the rear side of the connecting plate. The upper and lower ends of the worm are rotatably connected to the middle of the support frame. The worm and the worm gear mesh with each other. The upper end of the worm passes through the upper end of the support frame and is fixedly connected to the middle of the knob.

[0007] Preferably, a limit block is provided at the rear end of the limit rod.

[0008] Preferably, the operation panel has multiple grooves on its outer periphery.

[0009] Preferably, the lower four corners of the connecting plate are provided with connecting posts, and the outer periphery of the connecting posts is disposed inside the mounting holes.

[0010] Preferably, a permanent magnet is provided at the lower part of the connecting column, and a permanent magnet is provided on the bottom wall of the mounting hole.

[0011] Preferably, there are at least two limiting mechanisms.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The position of the limiting mechanism can be adjusted through the mounting holes on the control panel. The magnetic attraction between the connecting column and the permanent magnet in the mounting hole ensures the stable fixation of the limiting mechanism, facilitating quick adjustment of the overall limiting range according to the size of the LCD module. Simultaneously, rotating the knob drives the threaded rod to move the baffle through the meshing transmission of the worm gear and worm wheel. Combined with the guiding action of the limiting rod, the position of the baffle can be precisely adjusted. In conjunction with the limiting stop bar on the control panel, the LCD module can be limited in multiple directions, ensuring accurate alignment. The adjustment process is convenient and suitable for bonding LCD modules of various sizes, improving the versatility and operational efficiency of the equipment. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-3 As shown, an automatic alignment and bonding device for an LCD module includes an operation panel 1. A limit bar 2 is provided on the front left side of the operation panel 1. Several mounting holes 5 are provided at equal intervals on the upper part of the operation panel 1. Multiple limiting mechanisms 4 are provided on the upper part of the operation panel 1, and the limiting mechanisms 4 are connected to the mounting holes 5.

[0020] In this embodiment, the limiting mechanism 4 includes a connecting plate 401, a first connecting seat 402, a limiting rod 403, a baffle 404, a second connecting seat 405, a worm gear 406, a support frame 407, a worm 408, a threaded rod 409, and a knob 410. The lower part of the first connecting seat 402 is fixedly connected to the upper left and right sides of the connecting plate 401. The outer periphery of the limiting rod 403 is slidably connected to the inside of the first connecting seat 402. The front end of the first connecting seat 402 is fixedly connected to the lower left and right sides of the baffle 404. The lower part of the second connecting seat 405 is fixedly connected to the upper middle part of the connecting plate 401. The outer periphery of the threaded rod 409 is slidably connected to the second connecting seat 405. Inside 05, the front end of the threaded rod 409 is fixedly connected to the upper middle side of the baffle 404, the front side of the worm gear 406 is rotatably connected to the rear side of the connecting seat 405, the outer circumference of the threaded rod 409 is threadedly connected to the middle of the worm gear 406, the support frame 407 is installed on the rear side of the connecting plate 401, the upper and lower ends of the worm 408 are rotatably connected to the middle of the support frame 407, the worm 408 and the worm gear 406 mesh with each other, the upper end of the worm 408 passes through the upper end of the support frame 407 and is fixedly connected to the middle of the knob 410, the rear end of the limit rod 403 is provided with a limit block, the outer circumference of the operating plate 1 is provided with multiple grooves 3, and there are at least two limit mechanisms 4.

[0021] Specifically, firstly, based on the size of the LCD module, the position of the limiting mechanism 4 is adjusted through the mounting hole 5 on the operation panel 1. Rotating the knob 410 drives the worm gear 408 to rotate. Because the worm gear 408 meshes with the worm wheel 406, the worm wheel 406 rotates accordingly, causing the threaded rod 409, which is threaded into the middle of the worm wheel 406, to slide back and forth within the connecting seat 2 405. This, in turn, pushes the baffle 404 to move. Simultaneously, the limiting rods 403 within the connecting seats 1 402 on both sides of the baffle 404 slide synchronously for guidance. The limiting block at the rear end of the limiting rod 403 prevents it from dislodging. By adjusting the positions of the baffles 404 of the multiple limiting mechanisms 4, and in conjunction with the limiting stop bar 2 on the front left side of the operation panel 1, the LCD module is automatically aligned by multi-directional limiting. Afterward, the bonding operation can be repeated for LCD modules of the same size. When bonding operations are required for LCD modules of other sizes, the position of the limiting mechanism 4 can be readjusted according to the above steps.

[0022] In this embodiment, connecting posts 411 are provided at the four corners of the lower part of the connecting plate 401. The outer periphery of the connecting posts 411 is provided inside the mounting hole 5. A permanent magnet 412 is provided at the lower part of the connecting posts 411. A permanent magnet 412 is provided on the bottom wall of the mounting hole 5.

[0023] Specifically, the connecting posts 411 at the four corners of the connecting plate 401 of the limiting mechanism 4 are inserted into the corresponding mounting holes 5. The permanent magnets 412 at the bottom of the connecting posts 411 and the permanent magnets 412 on the bottom wall of the mounting holes 5 attract each other magnetically, thereby achieving stable fixation of the limiting mechanism 4.

[0024] Working principle:

[0025] First, based on the size of the LCD module, the position of the limiting mechanism 4 is adjusted through the mounting holes 5 on the operation panel 1. The connecting posts 411 at the four corners of the connecting plate 401 of the limiting mechanism 4 are inserted into the corresponding mounting holes 5. The permanent magnets 412 at the bottom of the connecting posts 411 and the permanent magnets 412 on the bottom wall of the mounting holes 5 are magnetically attracted to each other, thus achieving stable fixation of the limiting mechanism 4. Then, the knob 410 is rotated to drive the worm gear 408 to rotate. Because the worm gear 408 meshes with the worm wheel 406, the worm wheel 406 rotates accordingly, causing the threaded rod 409, which is threaded to the middle of the worm wheel 406, to be connected to the connecting seat 405. The baffle 404 moves by sliding back and forth, while the limiting rods 403 in the connecting seats 402 on both sides of the baffle 404 slide synchronously to guide it. The limiting block at the rear end of the limiting rod 403 prevents it from coming out. By adjusting the position of the baffle 404 of the multiple limiting mechanisms 4, and in conjunction with the limiting stop bar 2 on the front left side of the operation panel 1, the LCD module is automatically aligned by limiting it in multiple directions. Then, the bonding operation of LCD modules of the same size can be repeated. When bonding operation of LCD modules of other sizes is required, the position of the limiting mechanism 4 can be readjusted according to the above steps.
