Description

Technical Field

[0001] The utility model belongs to the technical field of feeding equipment for diffusion plate production, and particularly relates to a three-robot simultaneous feeding device. Background Technique

[0002] The biggest feature of the diffusion plate is that it causes great interference to light. Some of them will also produce light filtering, making some wavelengths unable to penetrate, resulting in color deviation. For example, if secondary light interference treatment (such as frosting, embossing) is carried out on the surface, the light transmittance is even lower due to the natural phenomenon of geometric optics. Therefore, the substrate used to make the diffusion plate should preferably have a lower refractive index, and the interference to light will be lower. Therefore, the diffusion plate is also relatively common in life. At present, when processing the diffusion plate, multiple layers of optical plates are usually laminated. Generally, the diffusion plate is composed of 2-3 optical plates respectively, and the multiple layers of plates are fed manually. However, when stacking the plates, it needs to be stacked multiple times to complete. This process is cumbersome, and the surface of the optical plate is easily damaged during the stacking process, resulting in low production efficiency of the diffusion plate. Moreover, this stacking method requires multiple employees to feed, resulting in high labor costs. Based on this, we propose a device that can feed simultaneously.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1-6 The utility model provides the following technical solutions: a three-manipulator simultaneous feeding device, comprising three parallel workbenches 1, each of which is equipped with two conveyor belts 2, and the conveyor belts 2 on the three workbenches 1 form two long conveying devices, and a feeding assembly 3 is installed on the top of each workbench 1, and a lifting device is installed at one end of the workbench 1, and a lifting plate 5 is installed on the lifting device, and a bakelite jig 6 for stacking optical plates is installed on the top of the lifting plate 5;

[0022] The lifting device is composed of two lifting components 4 , a lifting plate 5 is installed between the two lifting components 4 , and a paging component 7 is installed on the top of the lifting component 4 .

[0023] In this embodiment, the lifting assembly 4 includes a fixed plate 41 installed at the end of the workbench 1, a motor frame 42 is installed on the inner side of the fixed plate 41, a servo motor 43 is installed on the motor frame 42, a lifting screw 44 is rotatably installed on the outer side of the fixed plate 41, a first synchronous pulley 45 is installed on the top of the lifting screw 44, the output shaft of the servo motor 43 is fixedly connected to the second synchronous pulley 46, a synchronous belt 47 is transmission-connected between the first synchronous pulley 45 and the second synchronous pulley 46, a screw nut 48 is installed on the surface of the lifting screw 44, two guide rails 49 are also installed on the inner side of the fixed plate 41, a carrying plate 410 is slidably installed on the surface of the guide rail 49, the carrying plate 410 is connected to the screw nut 48, and the lifting plate 5 is installed on the surface of the carrying plate 410.

[0024] Specifically, the second synchronous pulley 46 is driven to rotate by the servo motor 43. Since the first synchronous pulley 45 and the second synchronous pulley 46 are driven by the synchronous belt 47, the first synchronous belt 47 will drive the lifting lead screw 44 to rotate. Therefore, the lead screw nut 48 will drive the carrying plate 410 to lift and lower. The guide rail 49 provided can improve the stability of the lifting of the carrying plate 410. The material lifting plate 5 is installed on the surface of the carrying plate 410. Therefore, the material lifting plate 5 will drive the bakelite jig 6 stacked with optical plates to be lifted to a high place and be loaded by the loading component 3.

[0025] In this embodiment, the loading component 3 includes a fixed frame 31 installed at the top end of the workbench 1. A first linear lead screw module 32 is installed at the top end of the fixed frame 31. A first driving motor 33 is installed at one end of the first linear lead screw module 32. A slide plate 34 is slidably installed on the surface of the first linear lead screw module 32. A second linear lead screw module 35 is installed on one side of the slide plate 34. A second driving motor 36 is installed at one end of the second linear lead screw module 35. A connecting frame 37 is slidably installed on the surface of the second linear lead screw module 35. A suction cup frame 38 is installed at the bottom end of the connecting frame 37.

[0026] Specifically, the first driving motor 33 and the first linear lead screw module 32 cooperate to adjust the position of the slide plate 34, so that the suction cup frame 38 moves to the top of the bakelite jig 6. Then, the second driving motor 36 and the second linear lead screw module 35 cooperate to make the connecting frame 37 drive the suction cup frame 38 to descend and adsorb the optical plates stacked on the surface of the bakelite jig 6. The optical plates adsorbed by the suction cup frame 38 will move to a high place with the connecting frame 37. Then, the slide plate 34 moves the suction cup frame 38 to the top of the conveyor belt 2. After that, the second linear lead screw module 35 makes the suction cup frame 38 descend and places the optical plates on the surface of the conveyor belt 2, thus completing the loading operation.

[0027] In this embodiment, the sheet separating component 7 includes a back plate 71 installed at the top of the outer side surface of the fixed plate 41. The top end of the back plate 71 is fixedly connected with a top plate 72. A connecting plate 73 is installed on one side of the top plate 72. A cylinder 74 is installed at the bottom of the connecting plate 73. The telescopic end of the cylinder 74 is connected with an ultrasonic sensor 75. Mounting frames 76 are installed on the opposite sides of the two top plates 72 in the lifting device. Ion air nozzles 77 are installed on the mounting frames 76.

[0028] Specifically, after the suction cup holder 38 adsorbs the optical sheet and moves it to a high place, the cylinder 74 pushes the ultrasonic sensor 75 to move to the position of the optical sheet, and the thickness of the adsorbed sheet is detected by the ultrasonic sensor 75. If the detected thickness of the sheet is not the thickness of a single sheet, the ion air nozzle 77 blows air on the sheet to separate the sheets, ensuring that the sheets fed each time are single sheets. When the ion air nozzle 77 blows air, it can clean the surface of the sheet, thereby improving the subsequent bonding effect of the sheet.

[0029] In this embodiment, several stoppers 8 are installed on the surface of the bakelite jig 6, and a slot 9 is formed on the surface of the bakelite jig 6, and a fiber optic material detection device is installed in the slot 9.

[0030] Specifically, the arranged stoppers 8 can improve the stacking neatness effect of the optical sheets on the surface of the bakelite jig 6, and the fiber optic material detection device installed in the slot 9 can detect the optical sheets on the surface of the bakelite jig 6. If it is detected that all the sheets on the surface of the bakelite jig 6 have been adsorbed and fed, the staff can be reminded in time to replenish the sheets on the surface of the bakelite jig 6.

[0031] In this embodiment, a belt cleaning device is installed at the top of the workbench 1 under the bottom of the conveyor belt 2.

[0032] Specifically, the belt cleaning device is a prior art and can clean the surface of the conveyor belt of the conveyor belt 2, thereby preventing dust on the surface of the conveyor belt 2 from affecting the subsequent bonding effect of the sheets.

[0033] Working principle: The arranged bakelite jig 6 facilitates the placement of stacked optical sheets, and the lifting assembly 4 can drive the lifting plate 5 to rise, thereby lifting the bakelite jig 6 on which the optical sheets are stacked. The second linear screw module 35 and the second driving motor 36 are used to make the suction cup holder 38 descend to suck up the sheets. After sucking up the sheets, the cylinder 74 drives the ultrasonic sensor 75 to detect the thickness of the sucked-up sheets. If it is detected that two sheets are sucked up, the ion air nozzle 77 blows air on the sheets to separate the sheets, thereby ensuring that each feeding is a single sheet. When the ion air nozzle 77 blows air, it can also clean the surface of the sheets to prevent dust on the surface of the sheets from affecting the stacking effect of the sheets. The first linear screw module 32 and the first driving motor 33 can move the suction cup holder 38 to the corresponding surface of the conveyor belt 2. The above-mentioned electrical equipment is all controlled by an external PLC controller. The device sucks up the sheets at the position of the lifting assembly 4 through three feeding components 3, separates the sheets by blowing air with the ion air nozzle 77, and after double-sheet detection by the ultrasonic sensor 75, feeds the sheets to the conveyor belt 2. The staff can also select two of the lifting devices and the feeding components 3 for simultaneous feeding of multiple sheets, and the staff can flexibly select a suitable feeding method.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
