Description

Technical Field

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

[0002] Backlights are widely used in industries such as touch screens, LCD / LCM, mobile phones, tablets, GPS, and solar cells. Currently, traditional manual or semi-manual coating methods not only result in poor coating quality and unevenness, but also have low production efficiency and high labor costs.

[0003] A backlight coating machine is disclosed in patent application CN 207497029 U, comprising an infeed conveyor belt, an outfeed conveyor belt, a film supply device, a pushing device, a pressing device, a film cutting device, and a feeding device. The backlight is conveyed to the film supply device via the infeed conveyor belt. After the pushing device detects the backlight's arrival, it pushes the backlight to the film. As the pushing device continues to advance the backlight, the film wraps around the front and bottom surfaces of the backlight. The film-wrapped backlight then enters the pressing device, which presses the backlight and film together, resulting in a better fit of the film to the backlight. After pressing, the backlight enters the film cutting device, which detects the backlight's arrival and cuts the film. After cutting, the feeding device delivers the film-wrapped backlight to the outfeed conveyor belt. This backlight coating machine requires no manual intervention during the coating process, resulting in high-quality, neat coating with high efficiency.

[0004] However, in the existing technology, the feeding conveyor belt and the discharging conveyor belt require a large amount of space, which is not convenient for installation and use in places with limited space, resulting in low practicality of the device. Utility Model Content

[0005] The purpose of this invention is to provide a backlight coating machine, which aims to solve the problem that in the prior art, the feeding conveyor belt and the discharging conveyor belt require a large length of space, making it inconvenient to install and use in places with limited space, resulting in low practicality of the device.

[0006] To achieve the above objectives, this utility model provides a backlight coating machine, including a coating mechanism, a base, and a operating mechanism. The operating mechanism includes a rotating seat, a rotating block, a rotating plate, multiple fixed frames, multiple sliding components, and fixed components. The rotating seat is fixedly connected to the base and located above the base. The rotating plate is fixedly connected to the rotating block and located below the rotating plate. The rotating block is rotatably connected to the rotating seat and located inside the rotating seat. The multiple fixed frames are fixedly connected to the rotating plate and located above the rotating plate. The coating mechanism is disposed at one end of the base. The multiple sliding components are disposed below the rotating plate. The fixed components are disposed on the base.

[0007] The sliding assembly includes a support frame, a rotating roller, and a pulley. The support frame is fixedly connected to the rotating plate and is located below the rotating plate. The rotating roller is rotatably connected to the support frame and the pulley and is located inside the support frame.

[0008] The base has an annular groove located above it, and one end of the pulley is slidably connected to the base and located within the annular groove.

[0009] The fixing component includes a mounting plate, a limiting rod, and a telescopic kit. The rotating plate has multiple limiting holes. The mounting plate is fixedly connected to one end of the base. The limiting rod is slidably connected to the mounting plate and extends into the limiting holes. The telescopic kit is disposed between the limiting rod and the mounting plate.

[0010] The telescopic kit includes a movable block and a telescopic spring. The movable block is fixedly connected to the limiting rod. Both ends of the telescopic spring are fixedly connected to the mounting plate and the movable block, respectively, and the limiting rod is located inside the telescopic spring.

[0011] This utility model discloses a backlight coating machine. The coating mechanism consists of a film supply device, a pushing device, a pressing device, and a film cutting device, all based on existing technology. When coating backlights, the operator places multiple backlights into multiple fixed frames. The operator rotates the rotating plate. When the fixed frame rotates to a position below the coating mechanism, the fixing component secures the rotating plate. The coating mechanism then coats the backlights. After coating, the operator rotates the rotating plate again, moving the uncoated backlights below the coating mechanism. Simultaneously, the operator removes the coated backlights and replaces them with uncoated ones. This method of coating backlights occupies a small space, allowing for installation and use in confined spaces, thus improving the device's practicality. Attached Figure Description

Detailed Implementation

[0018] Please see Figures 1 to 4 ,in, Figure 1 This is a structural schematic diagram of the backlight coating machine of this utility model. Figure 2 This is a front view of the backlight coating machine of this utility model. Figure 3 This is the utility model Figure 2 Enlarged view of the local structure at point A. Figure 4 This is a top view of the backlight coating machine of this utility model.

[0019] This utility model provides a backlight coating machine, including a coating mechanism 106, a base 101, and a running mechanism. The running mechanism includes a rotating seat 102, a rotating block 103, a rotating plate 104, multiple fixed frames 105, multiple sliding components, and a fixing component. The sliding component includes a support frame 107, a rotating roller 108, and a pulley 109. The base 101 has an annular groove 110. The fixing component includes a mounting plate 111, a limiting rod 114, and a telescopic assembly. The rotating plate 104 has multiple limiting holes 115. The telescopic assembly includes a moving block 112 and a telescopic spring 113. The aforementioned solution solves the problem in the prior art where the feeding conveyor belt and the discharging conveyor belt require a large amount of space, making it inconvenient to install and use in places with limited space, resulting in low practicality of the device.

[0020] In this embodiment, the rotating seat 102 is fixedly connected to the base 101 and located above the base 101; the rotating plate 104 is fixedly connected to the rotating block 103 and located below the rotating plate 104; the rotating block 103 is rotatably connected to the rotating seat 102 and located inside the rotating seat 102; multiple fixing frames 105 are fixedly connected to the rotating plate 104 and located above the rotating plate 104; the coating mechanism 106 is disposed at one end of the base 101; multiple sliding components are disposed below the rotating plate 104; and the fixing components are disposed on the base 101. When coating the backlight, the operator... Multiple backlights are placed within multiple fixed frames 105. The operator rotates the rotating plate 104. When the fixed frame 105 rotates to a position below the coating mechanism 106, the fixing component secures the rotating plate 104. The coating mechanism 106 then coats the backlights. After coating, the operator rotates the rotating plate 104 again and moves the uncoated backlight below the coating mechanism 106. Simultaneously, the operator removes the coated backlight and replaces it with an uncoated one. By using the aforementioned method to coat the backlights, the device occupies a small space and can be installed and used in confined spaces, thus improving its practicality.

[0021] Furthermore, the support frame 107 is fixedly connected to the rotating plate 104 and is located below the rotating plate 104. The rotating roller 108 is rotatably connected to the support frame 107 and the pulley 109 and is located inside the support frame 107.

[0022] Furthermore, the annular groove 110 is disposed above the base 101, and one end of the pulley 109 is slidably connected to the base 101 and located within the annular groove 110.

[0023] In this embodiment, when the operator rotates the rotating plate 104, the rotating block 103 rotates on the rotating seat 102, and at the same time, the multiple pulleys 109 slide within the annular groove 110. The multiple pulleys 109 provide auxiliary support for the rotating plate 104, ensuring that the rotating plate 104 will not tip over during operation. In addition, the contact area between the multiple pulleys 109 and the base 101 is small, making the rotating plate 104 rotate more easily and improving the structural rationality of the device.

[0024] Furthermore, the mounting plate 111 is fixedly connected to one end of the base 101, the limiting rod 114 is slidably connected to the mounting plate 111 and extends into the limiting hole 115, and the telescopic kit is disposed between the limiting rod 114 and the mounting plate 111.

[0025] Furthermore, the movable block 112 is fixedly connected to the limiting rod 114, and the two ends of the telescopic spring 113 are fixedly connected to the mounting plate 111 and the movable block 112 respectively, and the limiting rod 114 is located inside the telescopic spring 113.

[0026] In this embodiment, when coating the backlight, the operator places multiple backlights into multiple fixed frames 105 respectively, pulls the limiting rod 114 outward, causing the limiting rod 114 to move away from the limiting hole 115. At this time, the telescopic spring 113 is in a stretched state. The operator rotates the rotating plate 104. When the fixed frame 105 rotates to below the coating mechanism 106, the corresponding limiting hole 115 is aligned with the limiting rod 114. The operator then releases the moving block 112, and the telescopic spring 113 returns to its original position. The mechanism retracts and drives the limiting rod 114 into the limiting hole 115, fixing the rotating plate 104. The coating mechanism 106 then coats the backlight. After coating, the operator rotates the rotating plate 104 again and moves the uncoated backlight below the coating mechanism 106. Simultaneously, the operator removes the coated backlight and replaces it with an uncoated one. By using the aforementioned method to coat the backlight, the device occupies a small space and can be installed and used in confined spaces, thus improving its practicality.

[0027] When using this invention to coat backlights, the operator places multiple backlights into the multiple fixed frames 105, pulls the limiting rod 114 outward to move it away from the limiting hole 115, at which point the telescopic spring 113 is in a stretched state. The operator rotates the rotating plate 104, and when the fixed frame 105 rotates below the coating mechanism 106, the corresponding limiting hole 115 is aligned with the limiting rod 114. The operator then releases the moving block 112, and the telescopic spring 113 returns to its original position. The rotating plate 104 is fixed by rotating the limiting rod 114 into the limiting hole 115. The coating mechanism 106 coats the backlight. After coating, the operator rotates the rotating plate 104 again and moves the uncoated backlight below the coating mechanism 106. At the same time, the operator removes the coated backlight and replaces it with an uncoated one. By coating the backlight using the above method, the device occupies little space and can be installed and used in a small space, thus improving the practicality of the device.
