Description

Technical Field

[0001] This invention relates to the field of light guide plate processing technology, and in particular to a cleaning and drying device for light guide plate processing. Background Technology

[0002] During the processing of light guide plates, cleaning equipment is required to clean them. In the existing technology, the cleaning of light guide plates is generally done manually by holding a water hose to rinse the light guide plate and brushing it with cleaning tools. This manual cleaning method is not only inefficient, but also does not have the function of drying the light guide plate, which cannot meet the production requirements of light guide plates.

[0003] To address the above issues, some light guide plate cleaning and drying equipment has emerged on the market. The basic structure of existing equipment typically includes: a sealed or semi-sealed enclosure, a conveyor mechanism (such as rollers or belts) inside the enclosure, a spray pipe assembly above the conveyor mechanism, and a hot air drying device located at the rear of the cleaning area. The workflow is as follows: the conveyor mechanism sends the light guide plate into the enclosure, the spray pipes spray cleaning fluid for rinsing, and then the light guide plate is sent to the hot air drying area, where hot air generated by a fan and heater dries it.

[0004] However, existing light guide plate cleaning and drying equipment can only clean and dry the upper surface of the light guide plate in actual use, while the lower surface of the light guide plate suffers from problems such as incomplete cleaning and uneven drying due to being blocked by the conveying mechanism. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning and drying device for light guide plate processing, which aims to solve the technical problem that existing light guide plate cleaning and drying devices can only clean and dry the upper surface of the light guide plate in actual use, while the lower surface of the light guide plate is blocked by the conveying mechanism, resulting in incomplete cleaning and uneven drying.

[0006] To achieve the above objectives, the present invention provides a cleaning and drying equipment for light guide plate processing, including a frame, a stainless steel mesh belt conveyor line, a cleaning box, a drying box, two adjustable baffle mechanisms, and multiple support seats. The stainless steel mesh belt conveyor line is arranged on the frame, and the cleaning box and the drying box are arranged sequentially on the frame along the material conveying direction of the stainless steel mesh belt conveyor line.

[0007] The top of the frame is equipped with adjustable baffle mechanisms on both sides. Each adjustable baffle mechanism has a limit baffle at its output end. Both limit baffles are located above the stainless steel mesh belt conveyor. Multiple carrier seats are placed on the stainless steel mesh belt conveyor. The multiple carrier seats are located between the two limit baffles. Each carrier seat has a slot for vertically placing the light guide plate to be cleaned. High-pressure spray systems are provided on both sides of the interior of the cleaning box. Hot air channels are provided on both sides of the interior of the drying box.

[0008] Each of the adjustable baffle mechanisms further includes a mounting frame, a limiting shaft, a threaded rod, a drive assembly, a connecting bearing, and multiple limiting rods. The mounting frame is installed on the outside of the frame, and the limiting shaft is rotatably mounted on the mounting frame. The threaded rod is internally threaded to the limiting shaft. The end of the threaded rod near the stainless steel mesh belt conveyor is connected to the limiting baffle through the connecting bearing. Multiple limiting rods are provided on the side of the limiting baffle away from the stainless steel mesh belt conveyor. The end of each limiting rod away from the limiting baffle passes through the side of the frame. The drive assembly is also provided on the mounting frame, and a transmission gear is provided on the outside of the limiting shaft. The output end of the drive assembly meshes with the transmission gear.

[0009] Each of the drive components includes a servo motor, a gear reducer, and an output gear. The servo motor is mounted on the mounting bracket, the output end of the servo motor is provided with the gear reducer, and the output gear is provided with the output end of the gear reducer. The output gear meshes with the transmission gear.

[0010] Each of the limiting rotating shafts is provided with two limiting rings on its exterior, and the two limiting rings are respectively located on the front and rear sides of the mounting point of the mounting bracket.

[0011] In each of the limiting shafts, the two limiting rings facing each other are provided with an annular groove, and multiple balls are arranged inside the annular groove.

[0012] The cleaning and drying equipment for light guide plate processing also includes two protective shells, and each of the mounting brackets is also provided with a protective shell. The protective shells are disposed outside the output gear and the corresponding transmission gear.

[0013] Each of the protective shells includes a first half-shell and a second half-shell, which are located on both sides of the corresponding output gear. One side of the first half-shell is connected to the mounting bracket via a fixed foot, and the other side of the first half-shell is fitted with the second half-shell.

[0014] This invention discloses a cleaning and drying device for processing light guide plates, comprising a frame, a stainless steel mesh belt conveyor, a cleaning chamber, a drying chamber, two adjustable baffle mechanisms, and multiple support seats. By vertically placing the light guide plate to be cleaned on the support seats, both main surfaces of the light guide plate are fully exposed to the cleaning and drying environment. The high-pressure spray system located on both sides inside the cleaning chamber can simultaneously and symmetrically spray both surfaces of the vertically positioned light guide plate, achieving synchronous rinsing of both surfaces. This solves the problem of the lower surface being blocked by the support surface and unable to be cleaned during traditional horizontal conveying. Similarly, the hot air channels located on both sides inside the drying chamber can simultaneously blow hot air from both sides of the light guide plate, forming a double-sided airflow, ensuring uniform drying of both sides of the light guide plate, and completely eliminating the problem of incomplete drying and water residue on the lower surface caused by single-sided heating or uneven airflow.

Detailed Implementation

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] First embodiment:

[0025] Please see Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the cleaning and drying equipment for processing light guide plates according to the first embodiment. Figure 2 yes Figure 1 A magnified view of the local structure at point A. Figure 3 This is a schematic diagram of the internal structure of the washing box and drying box in the first embodiment. Figure 4 This is a schematic diagram of the limiting rotating shaft in the first embodiment.

[0026] This invention provides a cleaning and drying device for light guide plate processing: it includes a frame 101, a stainless steel mesh belt conveyor 102, a cleaning box 103, a drying box 104, two adjustable baffle mechanisms, and multiple support seats 105. Each adjustable baffle mechanism further includes a mounting frame 106, a limiting shaft 107, a threaded rod 108, a drive assembly, a connecting bearing 109, and multiple limiting rods 110. Each drive assembly includes a servo motor 111, a gear reducer 112, and an output gear 113. This solution solves the problem that existing light guide plate cleaning and drying equipment can only clean and dry the upper surface of the light guide plate during actual use, while the lower surface of the light guide plate suffers from incomplete cleaning and uneven drying due to obstruction by the conveying mechanism. Therefore, the aforementioned solution can be applied to the structure of a cleaning and drying device for light guide plate processing.

[0027] In this specific embodiment, the frame 101 is equipped with the stainless steel mesh belt conveyor line 102. The frame 101 is sequentially equipped with the cleaning box 103 and the drying box 104 along the material conveying direction of the stainless steel mesh belt conveyor line 102. Adjustable baffle mechanisms are provided on both sides of the top of the frame 101. Each adjustable baffle mechanism has a limit baffle 114 at its output end. Both limit baffles 114 are located above the stainless steel mesh belt conveyor line 102. Multiple support seats 105 are placed on the stainless steel mesh belt conveyor line 102, located between the two limit baffles 114. Each support seat 105 has a slot 115 for vertically placing the light guide plate to be cleaned. High-pressure spray systems 116 are provided on both sides of the interior of the cleaning box 103, and hot air channels 117 are provided on both sides of the interior of the drying box 104.

[0028] In this embodiment, by placing the light guide plate to be cleaned vertically on the support 105, the main surfaces on both sides of the light guide plate are fully exposed to the cleaning and drying environment. The high-pressure spray system 116 provided on both sides inside the cleaning box 103 can simultaneously spray the two surfaces of the vertical light guide plate symmetrically, thereby achieving synchronous rinsing of the two surfaces and solving the problem that the lower surface cannot be cleaned when the traditional horizontal conveyor is blocked by the support surface. Similarly, the hot air channels 117 arranged on both sides inside the drying chamber 104 can blow hot air from both sides of the light guide plate simultaneously, forming a double-sided airflow to ensure that both sides of the light guide plate are dried evenly. This completely eliminates the problem of incomplete drying and water stains on the lower surface caused by single-sided heating or uneven airflow. Furthermore, the adjustable baffle mechanism can adjust the distance between the two limiting baffles 114, thereby providing lateral constraint to the support seat 105. This prevents the support seat 105 from shifting under force when the light guide plate is being cleaned or dried, ensuring that the light guide plate always passes smoothly through the cleaning chamber 103 and the drying chamber 104 in a stable vertical posture.

[0029] Secondly, the mounting bracket 106 is mounted on the outside of the frame 101. The limiting shaft 107 is rotatably mounted on the mounting bracket 106. The threaded rod 108 is internally threaded to the limiting shaft 107. One end of the threaded rod 108 near the stainless steel mesh belt conveyor 102 is connected to the limiting baffle 114 through the connecting bearing 109. A plurality of limiting rods 110 are provided on the side of the limiting baffle 114 away from the stainless steel mesh belt conveyor 102. The end of each limiting rod 110 away from the limiting baffle 114 passes through the side of the frame 101. The mounting bracket 106 is also provided with the driving assembly. A transmission gear 118 is provided on the outside of the limiting shaft 107. The output end of the driving assembly meshes with the transmission gear 118.

[0030] In this embodiment, the drive assembly is activated, and the transmission gear 118 drives the limiting shaft 107 to rotate. Since the limiting shaft 107 does not shift during rotation, the threaded rod 108 rotates while simultaneously driving the limiting baffle 114 to translate under the cooperation of the connecting bearing 109 and the limiting rod 110. This completes the adjustment of the position of the limiting baffle 114, and the limiting baffle 114 provides lateral constraint to the carrier 105, preventing the carrier 105 from shifting under force when the light guide plate is being cleaned or dried.

[0031] Furthermore, the servo motor 111 is mounted on the mounting bracket 106, and the output end of the servo motor 111 is provided with the gear reducer 112. The output end of the gear reducer 112 is provided with the output gear 113, and the output gear 113 meshes with the transmission gear 118.

[0032] In this embodiment, the servo motor 111 is started, and the output speed is reduced by the gear reducer 112, which drives the output gear 113 to rotate. Since the output gear 113 meshes with the transmission gear 118, the limiting shaft 107 is driven to rotate on the mounting bracket 106.

[0033] Furthermore, each of the limiting shafts 107 is provided with two limiting rings 119 on its exterior. The two limiting rings 119 are located on the front and rear sides of the mounting point of the mounting bracket 106, respectively. Each of the two limiting rings 119 on the limiting shaft 107 is provided with an annular groove 120 facing each other. The annular groove 120 is provided with a plurality of balls 121 inside.

[0034] In this embodiment, the two limiting rings 119 make the structure more stable when the limiting shaft 107 rotates on the mounting frame 106, and the ball bearings 121 make the rotation of the limiting shaft 107 on the mounting frame 106 smoother.

[0035] When using the cleaning and drying equipment for light guide plate processing according to this embodiment, the light guide plate to be cleaned is placed vertically on the support 105, so that the main surfaces on both sides of the light guide plate are fully exposed to the cleaning and drying environment. The high-pressure spray system 116 arranged on both sides inside the cleaning box 103 can simultaneously spray symmetrically on both sides of the vertical light guide plate, realizing synchronous rinsing of the two surfaces, thereby solving the problem that the lower surface cannot be cleaned when the traditional horizontal conveyor is blocked by the support surface. Similarly, the hot air channels 117 arranged on both sides inside the drying chamber 104 can simultaneously blow hot air from both sides of the light guide plate, forming a double-sided airflow to ensure that both sides of the light guide plate are dried evenly. This completely eliminates the problem of incomplete drying and water stains on the lower surface caused by single-sided heating or uneven airflow. Furthermore, the drive assembly is activated, and the transmission gear 118 drives the limiting shaft 107 to rotate. Since the limiting shaft 107 does not shift during rotation, the threaded rod 108 rotates while the connecting bearing 109 and the limiting rod 110 cooperate to drive the limiting baffle 114 to move horizontally, thereby adjusting the position of the limiting baffle 114. The limiting baffle 114 provides lateral constraint to the support seat 105, preventing the support seat 105 from shifting under force during cleaning or drying of the light guide plate, and ensuring that the light guide plate always passes smoothly through the cleaning chamber 103 and the drying chamber 104 in a stable vertical posture.

[0036] Second embodiment:

[0037] Based on the first embodiment, please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the cleaning and drying equipment for processing light guide plates according to the second embodiment. Figure 6 for Figure 5 A magnified view of the local structure at point B.

[0038] The present invention provides a cleaning and drying device for processing light guide plates, which further includes two protective shells, each of which includes a first half-shell 201 and a second half-shell 202.

[0039] In this specific embodiment, each mounting bracket 106 is also provided with a protective shell. The protective shell is disposed outside the output gear 113 and the corresponding transmission gear 118. By providing the protective shell, the output gear 113 and the transmission gear 118 are protected, and the external environment is prevented from affecting the meshing of the output gear 113 and the transmission gear 118.

[0040] The first half-shell 201 and the second half-shell 202 are respectively located on both sides of the corresponding output gear 113. One side of the first half-shell 201 is connected to the mounting bracket 106 via a fixing foot 203, and the second half-shell 202 is installed on the other side of the first half-shell 201. After placing the first half-shell 201 and the second half-shell 202 on both sides of the corresponding output gear 113, the fixing foot 203 is fixed on the mounting bracket 106, and the second half-shell 202 is fixed on the first half-shell 201, thereby completing the installation of the protective shell.

[0041] When using the cleaning and drying equipment for light guide plate processing according to this embodiment, after placing the first half-shell 201 and the second half-shell 202 on both sides of the corresponding output gear 113, the fixing foot 203 is fixed on the mounting bracket 106, and the second half-shell 202 is fixed on the first half-shell 201, thereby completing the installation of the protective shell. The protective shell protects the output gear 113 and the transmission gear 118, preventing the external environment from affecting the meshing of the output gear 113 and the transmission gear 118.

[0042] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
