Description

Technical Field

[0001] This invention relates to the field of diffusion plate processing technology, and more specifically, to an automatic loading and unloading device for diffusion plates. Background Technology

[0002] As a functional material with special optical or acoustic properties, diffuser plates are widely used in fields such as liquid crystal displays, LED lighting, and imaging display systems due to their ability to uniformly disperse molecules. In the production and processing of diffuser plates, subsequent processing such as drilling and cutting is often required on batches of stacked diffuser plates.

[0003] However, in existing technologies, the processing and feeding of diffusion plates largely relies on manual operation, whereby the diffusion plates are manually stacked one by one onto the processing table of the forming machine. This method not only suffers from low production efficiency, making it difficult to meet the needs of large-scale production; more importantly, manual stacking makes it difficult to ensure the neatness of the diffusion plates, easily leading to large errors in plate positioning, which in turn affects the accuracy of subsequent processing and may ultimately have an adverse impact on the product quality of the diffusion plates.

However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential.

They are merely used to distinguish components or operations described using the same technical terms, and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

If a combination of technical solutions is contradictory or impossible to implement, such a combination should be considered nonexistent and not within the scope of protection claimed by this invention.

[0018] See Figures 1-4 , Figure 1 This is a schematic diagram of the automatic loading and unloading equipment for the diffuser plate in the embodiment. Figure 2 This is a schematic diagram of the material handling device in the embodiment. Figure 3 This is a schematic diagram of the material handling device in the embodiment. Figure 4 This is a schematic diagram of the conveying unit structure in the embodiment. An automatic diffusion plate loading and unloading device in this example includes: a loading device 1, a conveying device 2, and an unloading device 3. The loading device 1 includes an adjacent lifting and stacking device 11 and a balancing device 12. The loading device 1 also includes a picking device 13, which is mounted above the loading device 11 and the balancing device 12 and reciprocates above them. The balancing device 12 includes a balancing section 121 and a first conveying section 122. The balancing section 121 is driven at one end of the first conveying section 122, and the other end of the first conveying section 122 extends outward. The conveying device 2 is located on one side of the other end of the second conveying section 122 and includes a conveying section 21 and a second conveying section 22. The second conveying section 22 is perpendicular to the first conveying section 122, and the conveying section 21 is driven at the second conveying section 22. The unloading device 3 is located beside the conveying device 2 and has an unloading transport mechanism 31. The conveying section 21 can rotate towards the second conveying section 22 or the unloading transport mechanism 31. In this example, the lifting and stacking device 11 adopts a scissor lift platform, and both the first conveying section 122 and the second conveying section 22 adopt synchronous belt linear drive modules.

[0019] In practice, the diffuser plate processing equipment is positioned on the side of the first conveyor section 122 facing away from the second conveyor section 22 and directly opposite the handling section 21. During operation, workers use a forklift to transport the diffuser plate stack to the lifting and stacking device 11. At this time, the picking device 13 picks up the diffuser plates one by one from the lifting and stacking device 11 and stacks them into the assembling device 13. After the assembling device 13 neatly arranges the stacked diffuser plates, the first conveyor section 122 transports the assembling device 12 between the processing equipment and the second conveyor section 22. Then, the second conveyor section 122 drives the handling device 2 towards the assembling device 12 and lifts the diffuser plate stack within it. The assembling device 12 then returns to its original position, and the handling device 2 continues to move towards... The device moves toward the processing equipment and places the diffuser plate stack on the loading platform of the processing equipment. The conveying device 2 then retracts, and the processing equipment begins processing. After processing is completed, the conveying device 2 moves toward the processing equipment and lifts the processed diffuser plate stack. It then retracts to its original position and rotates toward the unloading conveyor 31, placing the diffuser plate stack onto the unloading conveyor 31. At this point, the unloading conveyor 31 can transport the processed diffuser plate stack away. This completes the automatic loading and unloading process for diffuser plate processing, which not only greatly improves loading and unloading and ensures processing accuracy, but also greatly reduces the labor intensity of workers.

[0020] Furthermore, the material handling unit 121 includes a machine base 1211 and a lifting and bearing mechanism 1212 and multiple material handling mechanisms 1213 disposed on the machine base 1211. The lifting and bearing mechanism 1212 is disposed at the center of the machine base 1211, and the multiple material handling mechanisms 1213 are disposed around the lifting and bearing mechanism 1212. The material handling mechanisms 1213 can be close to or far away from the lifting and bearing mechanism 1212. In this example, the lifting and bearing mechanism 1212 includes a material lifting module 12121 and a material bearing platform 12122. The material lifting module 12121 is a screw lifting module, and the material bearing platform 12122 is connected to the material lifting module 12121. The material bearing platform 12122 includes a bearing plate 121221 and multiple support platforms 121222. The multiple support platforms 121222 are arranged sequentially along the length of the bearing plate 121221. Thus, when the diffusion plate is stacked on the support platform 121222, the clearance space formed between the multiple support platforms 121222 facilitates transportation.

[0021] The material aligning mechanism 1213 includes a horizontal drive module 12131 and a material aligning baffle 12132. The horizontal drive module 12131 is mounted on the machine base 1, with one end facing the lifting and supporting mechanism 1212. One end of the material aligning baffle 12132 is driven onto the horizontal drive module 12131, and the other end extends vertically upward. The horizontal drive module 12131 is a linear screw module. In this example, there are four sets of material aligning mechanisms 1213, which are respectively arranged around the lifting and supporting mechanism 1212. That is, when the diffuser plates are stacked on the lifting and supporting mechanism 1212, the horizontal drive modules 12131 of the four sets of material aligning mechanisms 12133 simultaneously drive their corresponding material aligning baffles 12132 toward the diffuser plate stack, thereby aligning the diffuser plates in the stack.

[0022] Furthermore, the material handling device 13 includes a transfer bracket 131 and two sets of material handling mechanisms 132. The transfer bracket 131 is mounted above the lifting and stacking device 11 and the balancing device 12. The transfer bracket 131 is provided with two sets of sliding components 1311. The two sets of sliding components 1311 are arranged along the width direction of the transfer bracket 131 and are respectively arranged along the length direction of the transfer bracket 131. The two sets of material handling mechanisms 132 include a material handling part 1321 and a material handling drive part 1322. The two sets of material handling parts 1321 are slidably disposed on the sliding components 1311 and are arranged along the length direction of the transfer bracket 131. The two sets of material handling drive parts 1322 are respectively disposed on the outside of the two sets of sliding components 1311 and are respectively connected to the material handling part 1321. Understandably, by setting up two sets of material handling mechanisms 132, during operation, one set of material handling mechanisms 132 will pick up the diffuser plate inside the lifting and stacking device 12, and then the other set of material handling mechanisms 132 will transport it to the material handling device 12, so as to avoid the air pressure between the diffuser plates affecting the working efficiency.

[0023] Specifically, the material handling unit 1321 includes a transfer plate 13211, multiple mounting brackets 13212, and multiple sets of material handling components 13213. The transfer plate 13211 is slidably mounted on the sliding component 1311 and is drively connected to the material handling drive unit 1322. The multiple mounting brackets 13212 are arranged along the length of the transfer plate 13211 on its lower surface. The multiple sets of material handling components 13213 are mounted on the bottom ends of the mounting brackets 13212. The mounting brackets 13212 in the two sets of material handling units 1321 protrude towards each other and interweave, thus enabling the two sets of material handling units to... When the material handling mechanisms 132 are close to each other, the material handling components 13213 are closest in position and do not affect each other. The material handling components 13213 include a push drive 132131, a mounting plate 132132 and multiple material handling heads 132133. One end of the push drive 1302131 is fixed to the bottom end of the mounting frame 13212, and its drive end is set vertically downward. The mounting plate 132132 is installed on the drive end of the push drive 132131 and is set along the length direction of the transfer bracket 131. The multiple material handling heads 132133 are arranged along the length direction of the mounting plate 132132. Among them, the material picking head 132133 adopts a pneumatic suction head, and the downward drive 132131 adopts a cylinder. It can be understood that when it is necessary to pick up the diffuser plate from the stacking device 12 during operation, along the length direction of the diffuser plate, the downward drive 132131 of multiple sets of material picking components 13213 sequentially drives the material picking head 132133 to pick up the diffuser plate and lift it. In this way, the diffuser plate can be lifted from one end to the other in sequence, thereby avoiding the air pressure between the diffuser plates from affecting the material picking.

[0024] Furthermore, the conveying unit 21 includes a rotating mechanism 211 and a conveying mechanism 212. The rotating mechanism 211 is mounted on the second conveying unit 22, and the conveying mechanism 212 is driven by the rotating mechanism 211. The rotating mechanism 211 adopts a servo rotating platform.

[0025] The handling mechanism 212 includes a stand 2121, a lifting drive module 2122, and a handling module 2123. The stand 2121 is mounted on and driven to the rotating mechanism 211. The lifting drive module 2122 is located at the center of the stand 2121 and extends from the top to the bottom of the stand 2121. The handling module 2123 is located on the side wall of the stand 2121 and driven to the lifting drive module 2122. In this example, the lifting drive module 2122 is a screw-driven lifting module.

[0026] The handling module 2123 includes a connecting frame 21231, a telescopic drive module 21232, and two transfer arms 21233. The connecting frame 21231 is slidably connected to three adjacent side walls of the upright frame 2121 and is drive-connected to the lifting drive module 2122. The telescopic drive module 21232 is located on one side of the connecting frame 21231, and the two transfer arms 21233 are located on both sides of the telescopic drive module 2122 and are slidably connected to both sides of the connecting frame 21231. The telescopic drive module 21232 includes a telescopic drive 212321 and a dual-output reduction gearbox 212322. The telescopic drive 212321 is driven to the dual-output reduction gearbox 212322. The dual-output reduction gearbox 212322 has output teeth at both ends. The inner sides of the two transfer arms 21233 are respectively provided with meshing teeth 212331. The transfer arms 21233 are driven to the output teeth of the dual-output reduction gearbox 212322 through the meshing teeth 212331. That is, during operation, the two transfer arms 21233 lift the diffuser plate stack. At the same time, the telescopic drive module 21232 enables the transfer arms 21233 to extend and retract, allowing them to extend into the shelter to lift the diffuser plate stack, and vice versa, allowing them to retract from the shelter after the diffuser plate stack is placed.

[0027] Furthermore, the unloading and transport mechanism 31 includes an unloading trolley 311, which includes a trolley body 3111 and multiple sets of first roller assemblies 31111. The multiple sets of first roller assemblies 31111 are arranged along the length of the trolley body 3111 and are spaced apart to form multiple clearance positions 31112. That is, after the diffuser plate is processed, the transport unit 21 transports the diffuser plate stack onto the unloading trolley 311, and the worker can push the processed diffuser plate out for collection. It can be understood that the first roller assembly 31111 can be used to reduce the friction between the diffuser plate and the unloading trolley 311, which facilitates subsequent transfer. The clearance positions 31112 are used to avoid the clearance of the transfer arm 21233, and also facilitate subsequent transfer by workers using forklifts.

[0028] Preferably, the unloading device 3 further includes a tray storage mechanism 32, which includes a support frame 321 and two support platforms 322. The support frame 321 is mounted on one side of the unloading trolley 311, and the two support platforms 321 are arranged along the width of the support frame 321 on one side of the support frame 321 and are located directly above the unloading trolley 311. Each support platform 321 has a second roller assembly 3211 on its upper surface along its length. It can be understood that during operation, trays are used to stack the diffusion plates to prevent uneven stress and deformation of the diffusion plates during transport. Therefore, after the conveying unit 21 stacks the diffusion plates of the material assemblies into the processing equipment, it moves to the tray storage mechanism 32 and removes the trays from the tray storage mechanism 32 and places them into the material assemblies 12.

[0029] In summary, in this example, the automated loading and unloading of the diffusion plate is achieved through the cooperation of the loading device, the handling device, and the unloading device. This not only greatly improves the loading and unloading process and ensures the processing accuracy, but also significantly reduces the labor intensity of workers.

[0030] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
