[0030] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0031] 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 of 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.
[0032] Please refer to Figures 1 to 9 The utility model provides a convenient polarizer loading device. The preferred embodiment of the convenient polarizer loading device of the utility model includes a base 1 and a loading platform 2.
[0033] The loading table 2 is used for stacking polarizers. A loading limit mechanism for aligning the polarizers and a driving mechanism for driving the loading limit mechanism to move so as to align the polarizers are provided on the base 1 and the loading table 2. A material upper limit sensor 3 is provided on the top of the loading limit mechanism, a material shortage sensor 4 is provided on the base 1, and a blowing mechanism 5 for separating the polarizers is also provided on the top of the loading limit mechanism.
[0034] In this embodiment, after the polarizers are stacked and placed on the loading platform 2, the driving mechanism drives the loading limit mechanism to move to align the polarizers, and then the driving mechanism drives the loading platform 2 to rise. When the material upper limit sensor senses that the polarizer has risen to the specified position, it will send a signal to the material picking robot (shown in the figure) to let the material picking robot grab the polarizer. At the same time, the blowing mechanism 5 will blow compressed air between the polarizers to separate the stuck polarizers. The polarizer below falls to the position to be picked up under the action of gravity, ensuring that the material picking robot grabs only one polarizer.
[0035] This embodiment uses the material upper limit sensor to ensure that the material picking position of the material picking robot is at the same position each time, thereby reducing the risk of collision with the machine caused by inconsistent material picking heights each time.
[0036] When the material taking robot has taken away multiple polaroids, the material upper limit sensor 3 cannot sense the position of the polaroids, and the driving mechanism drives the loading platform 2 to rise until the material upper limit sensor 3 senses the polaroids again and stops. This action is repeated until the material taking robot has taken the last polaroid. At this time, the material shortage sensor 4 senses that the polaroids have been taken from the loading platform 2 and alarms, and reminds manual intervention to reload the material.
[0037] Furthermore, in this embodiment, the loading limit mechanism includes a plurality of loading limit plates 6 arranged around the base 1 and the loading platform 2, a first loading limit plate 6 adjustment groove is arranged on both sides of the base 1 and the loading platform 2, and a second loading limit plate 6 adjustment groove is arranged at both ends of the base 1 and the loading platform 2.
[0038] Among them, the adjustment range of the loading limit plate 6 in the first loading limit plate 6 adjustment groove and the second loading limit plate 6 adjustment groove is 10 mm.
[0039] Furthermore, in this embodiment, the driving mechanism includes an X-axis motor 7 arranged on the base 1 for driving the loading limit plate 6 to move along the X-axis direction in the adjustment groove of the first loading limit plate 6, a Y-axis motor 8 arranged at the bottom of the base 1 for driving the loading limit plate 6 to move along the Y-axis direction in the adjustment groove of the second loading limit plate 6, and a Z-axis screw motor 9 arranged at the bottom of the base 1 for driving the loading table 2 to move up and down.
[0040] The top surface of the base 1 is provided with an X-axis lead screw 10 and an X-axis guide rail 11 , and the bottom surface of the base 1 is provided with a Y-axis lead screw 12 and a Y-axis guide rail 13 .
[0041] A forward-rotating screw nut 14 and a reverse-rotating screw nut 15 are arranged at intervals in the middle of the X-axis screw 10 .
[0042] A forward-rotating screw nut 14 and a reverse-rotating screw nut 15 are arranged at intervals in the middle of the Y-axis screw 12 .
[0043] This embodiment greatly improves the accuracy of adjusting the preset size of the polarizer and the convenience of material discharge by controlling the X-axis motor 7 and the Y-axis motor 8. At the same time, a forward-rotating screw nut 14 and a reverse-rotating screw nut 15 are used on one screw to achieve movement in opposite directions with one screw, which greatly simplifies the overall structure.
[0044] Furthermore, in the present embodiment, a scraper plate 16 is provided on the top of the loading limit plate 6 , and a serrated structure 18 is provided on the scraper plate 16 , which is in a stepped serrated shape and shrinks inwards.
[0045] In this embodiment, the scraper plate 16 is combined with air blowing to avoid the polarizer from sticking when taking out the material.
[0046] Furthermore, in this embodiment, the convenient polarizer loading device also includes an operating table, on which a loading button and a discharge completion button are provided.
[0047] In this embodiment, the convenient polarizer loading device also includes a material picking robot for grabbing the polarizer.
[0048] In this embodiment, Z-axis guide rods 17 are provided at the four corners of the base 1 and the loading platform 2 .
[0049] The working principle of the convenient polarizer feeding device of the utility model is described in detail below.
[0050] When the polarizer needs to be placed on the loading table 2, first press the loading button on the operating table. The loading table 2 is driven by the Z-axis screw motor 9 to descend to the lowest end, and then the loading limit plate 6 is driven by the X-axis motor 7 and the Y-axis motor 8 to open 10 mm each, so as to leave a loose space for manual discharge.
[0051] After manual feeding is completed, press the feeding completion button on the operating table, and the feeding limit plate 6 is tightened by 10mm under the drive of the X-axis motor 7 and the Y-axis motor 8 to reach the preset polarizer size, and the polarizers that are not neatly arranged during manual feeding are aligned, and then the feeding table 2 moves upward under the drive of the Z-axis screw motor 9. When the material upper limit sensor 3 senses the polarizer, the feeding table 2 stops moving. During the up and down movement of the feeding table 2, the Z-axis guide rod 17 plays a guiding role to ensure that the feeding table 2 is level and will not tilt.
[0052] After the material upper limit sensor 3 senses that the polarizer has risen to the specified position, it will send a signal to the material picking robot to let the material picking robot come and grab the polarizer. When the robot sucks up and lifts the polarizer, the edge of the polarizer will first pass through the scraper plate 16. The step-shaped serrations and inward contraction design of the scraper plate 16 will separate the adhered polarizer from the edge. At this time, the blowing mechanism 5 behind the scraper plate 16 will blow the compressed air along the gap scraped by the scraper plate 16 to the middle of the entire material, so that air isolation is formed between the two adhered polarizers, so that the adhered polarizers are separated, and the lower polarizer will fall to the position to be picked up under the action of gravity, ensuring that the robot grabs only one polarizer.
[0053] When the robot has taken away multiple polaroids, the material upper limit sensor 3 cannot sense the position of the polaroids, and the Z-axis screw motor 9 will drive the loading platform 2 to rise until the material upper limit sensor 3 senses the polaroid again and stops. This action is repeated until the robot has taken the last polaroid. At this time, the material shortage sensor 4 senses that the polaroid has been taken from the loading platform 2 and alarms, and reminds manual intervention to reload the material.
