Description

Technical Field

[0001] This utility model relates to the field of backlight module processing technology, and in particular to a backlight module coating device. Background Technology

[0002] In the manufacturing process of backlight modules, a protective film is typically applied to the module surface to ensure its safety and cleanliness during transportation and subsequent processing. This protective film effectively prevents foreign matter from entering and guarantees module quality. Existing laminating equipment usually includes a machine for conveying backlight modules, as well as a pressing assembly and a cutting assembly mounted on the machine. A specific example is an automatic laminating device for backlight modules disclosed in Chinese Patent Publication No. CN220924637U.

[0003] However, existing film coating equipment has certain shortcomings. Particularly in the design of the film feeding cylinder, it is typically mounted above the conveyor roller table, resulting in a high position for the cylinder. Changing the cylinder requires operators to climb or use other auxiliary equipment, which not only increases the difficulty of replacement and reduces production efficiency but also poses certain safety hazards.

[0004] Based on this, in order to further optimize the ease of replacing the film tube of the existing coating device, we propose a backlight module coating device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the high position of the film tube increasing the difficulty of replacement, and to propose a backlight module coating device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The support assembly includes a first arm fixed to the end of the lifting assembly and a second arm movably connected to the first arm, with positioning elements on both sides of the positioning membrane tube provided between the first arm and the second arm.

[0010] Furthermore, the lifting assembly includes a sleeve and a lifting rod that is movably inserted into the sleeve, the lifting rod being circumferentially locked to the sleeve;

[0011] The inner bottom of the sleeve is fixedly connected to a drive component that moves the lifting rod.

[0012] Furthermore, the bottom outer side of the sleeve is provided with an installation port communicating with its inner cavity, and the installation port is located at the drive component;

[0013] The outer side of the sleeve is fixedly connected to a cover plate that covers the installation port by a locking member.

[0014] Furthermore, the base assembly includes a base, the bottom end of the sleeve extends through the inner hole of the base and is rotatably connected to the base, and a motor is fixedly connected to the top of the base, the shaft end of the motor extends through the inner cavity of the base and is driven by the sleeve through gears.

[0015] Furthermore, the positioning element on the first arm is threadedly connected to the first arm, and the positioning element on the second arm is fixedly connected to the second arm;

[0016] A locking structure is also provided between the first arm and the second arm.

[0017] Furthermore, the locking structure includes a drive rod inserted into the second arm, and a spring is fixedly connected between the drive rod and the inner hole of the second arm;

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-5 As an embodiment of this utility model, a backlight module coating device is disclosed. The coating device includes a conveyor table 1, a pressing mechanism 2 and a cutting mechanism 3 mounted on the conveyor table 1. The specific structure and principle of the conveyor table 1, the pressing mechanism 2 and the cutting mechanism 3 have been disclosed in the prior art and will not be described in detail here.

[0029] Specifically, this device also includes a base assembly 4 installed on the side of the conveyor table 1;

[0030] A lifting assembly 5 is rotatably connected above the base assembly 4, and a support assembly 7 for carrying the membrane cylinder 6 is fixedly connected to the top of the lifting assembly 5.

[0031] The support assembly 7 includes a first arm 71 fixed to the end of the lifting assembly 5 and a second arm 72 movably connected to the first arm 71. Positioning members 73 on both sides of the positioning membrane cylinder 6 are provided between the first arm 71 and the second arm 72.

[0032] In some embodiments, the lifting assembly 5 of the present invention includes a sleeve 51 and a lifting rod 52 that is movably inserted into the sleeve 51. The lifting rod 52 is circumferentially locked to the sleeve 51. In a preferred embodiment, a guide groove can be opened on the outside of the lifting rod 52, and a protrusion can be provided in the inner hole of the sleeve 51. The sliding limit between the sleeve 51 and the lifting rod 52 can be realized through the sliding cooperation between the protrusion and the guide groove.

[0033] The inner bottom of the sleeve 51 is fixedly connected to a drive component 53 that pushes the lifting rod 52 to move. In this embodiment, the drive component 53 is preferably a hydraulic cylinder. The lifting rod 52 is raised and lowered by the hydraulic cylinder to adjust the height of the membrane cylinder 6. When adjusted to a lower height, it is convenient to disassemble and replace the membrane cylinder 6 to improve the efficiency of the operation.

[0034] Based on the above embodiments, in this embodiment, the bottom outer side of the sleeve 51 is provided with an installation port that communicates with its inner cavity. The installation port is located at the drive member 53. By opening the installation port, it is convenient to install and disassemble the internal drive member 53.

[0035] Of course, in order to protect the internal drive component 53, in this embodiment, the outer side of the sleeve 51 is fixedly connected with a cover plate 54 covering the installation port by a locking member. Specifically, in this embodiment, the locking member is set as a bolt.

[0036] Furthermore, in this embodiment, the base assembly 4 includes a base 41, which is fixed to the ground by fasteners such as expansion bolts. The bottom end of the sleeve 51 passes through the inner hole of the base 41 and is rotatably connected to the base 41. A motor 42 is fixedly connected to the top of the base 41, and the shaft end of the motor 42 passes through the inner cavity of the base 41 and is driven by the sleeve 51 through gears.

[0037] It should be noted that the base 41 in this embodiment has a cavity inside. Gears are fixedly connected to the shaft end of the motor 42 and the bottom end of the sleeve 51. The two gears mesh with each other. When it is necessary to adjust the rotation angle of the membrane tube 6, the motor 42 works to drive the sleeve 51 to rotate through the gears, thereby adjusting the circumferential position of the membrane tube 6. The purpose of this circumferential angle adjustment is to avoid the top of the frame when moving up and down, and at the same time, to achieve more operating angles, so as to further optimize the ease of disassembling the membrane tube.

[0038] It should be noted that in this embodiment, the positioning member 73 on the first arm 71 is threadedly connected to the first arm 71, and the positioning member 73 on the second arm 72 is fixedly connected to the second arm 72.

[0039] A locking structure is also provided between the first arm 71 and the second arm 72.

[0040] In other words, since the second arm 72 and the first arm 71 are interlocked in this embodiment, the distance between the two positioning members 73 can be changed by adjusting the position of the threaded positioning member 73 on the first arm 71 and the position of the second arm 72, depending on the width of the membrane tube 6. This allows for adaptation to membrane tubes 6 of different widths within a certain range. Of course, the positioning member 73 in this embodiment is set as a disc-shaped member.

[0041] Based on the above embodiments, the locking structure in this embodiment includes a drive rod 74 inserted into the second arm 72, and a spring 75 is fixedly connected between the drive rod 74 and the inner hole of the second arm 72;

[0042] A limiting bead 76 is movably connected to the outer side of the second arm 72. Of course, a through hole should be opened on the outer side of the second arm 72. The diameter of the through hole is smaller than the diameter of the limiting bead 76, so as to prevent the limiting bead 76 from sliding outward from the through hole. An annular groove 77 for accommodating the limiting bead 76 is opened on the outer side of the drive rod 74.

[0043] In addition, a plurality of locking ring grooves 78 are provided in the inner hole of the first arm 71 along the axial direction, and the limiting bead 76 is engaged with the locking ring grooves 78.

[0044] In this embodiment, the design of the push-type drive rod 74 allows for adjustment or disassembly of the second arm 72 when the drive rod 74 is pressed. When the outer annular groove 77 aligns with the limiting bead 76, the limiting bead 76 has a certain amount of room to move in the annular groove 77. At this time, the limiting bead 76 separates from the locking annular groove 78 in the first arm 71, allowing the second arm 72 to be pulled outwards freely to adjust its length or position. Alternatively, the second arm 72 can be pulled directly out of the first arm 71, thus completing the adjustment or disassembly of the second arm 72.

[0045] In summary, by employing a rotatable lifting assembly 5, when replacing the membrane cylinder 6, the membrane cylinder 6 can be first rotated to the side of the conveyor table 1 to avoid it. After adjustment, the membrane cylinder 6 can be adjusted to a low position, thereby improving the ease of disassembly and replacement of the membrane cylinder 6. Secondly, the membrane cylinder 6 is supported by a first arm 71 and a second arm 72, and the second arm 72 is fixed by a locking structure, which improves the efficiency of adjustment and disassembly, further optimizing the ease of operation of the membrane cylinder 6.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
