[0033] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] This embodiment provides a paper storage mechanism 1, such as Figure 1-3 As shown, it includes a support assembly 10 for storing paper and driving the paper to move up and down, and a monitoring assembly 20 for monitoring the number of stacked paper and the inclination. Among them, the support assembly 10 includes a stand 12 surrounded by a space for storing paper, a tray 11 placed inside the stand 12 and used to support and place paper, a base 13 for fixing the stand 12, and a motor for driving the tray 11 to drive the paper to move up and down in the vertical direction, and the motor is arranged below the base 13. In this embodiment, two sets of stand 12 are arranged in opposite positions, and adjacent stand 12 are arranged with a gap, so as to place the base 13 and surround a storage bin with an open structure for placing paper, and all stand 12 are fixed to the base 13 by connecting members.

[0035] like Figure 1-2 As shown, the monitoring component 20 includes a limit sensor for monitoring the number of paper stacks and a monitoring component for monitoring the inclination of paper. All sensors and monitoring components are constructed on the outer wall surface of the stand 12 and are arranged toward the side of the paper in the inner space of the stand 12.

[0036] Among them, the limit sensor for monitoring the number of stacked sheets includes a high position sensor 21 and a low position sensor 22. Only two sensors are needed for monitoring the limit height of stacked sheets, which can be arranged on the same side or on different sides along the height direction of the stand 12. That is, the high position sensor 21 and the low position sensor 22 can be arranged on the outer wall surface of the same stand 12, or on the outer wall surface of the stand 12 arranged in opposite positions, or on the outer wall surfaces of the stand 12 adjacent to each other on different sides.

[0037] Regardless of whether the configuration is on the same side, in alignment, or on the opposite side, the position of the high-position sensor 21 and the low-position sensor 22 is always located on the center axis of the paper, that is, both are located at the center line of the width of the stand 12, so as to facilitate the observation of the accuracy of the paper placement position. When the top or bottom paper is tilted, if the high-position sensor 21 and the low-position sensor 22 are located at a non-center axis position of the stand 12, the height they monitor may not be consistent with the limit position, and the number of papers cannot be accurately determined.

[0038] When the number of reserve papers is initially placed, the height of the topmost paper generally does not exceed the upper limit, but should be between the upper limit and the lower limit. As the papers are separated and used, the number of papers will gradually decrease. Each time the paper suction mechanism moves to the paper storage mechanism 1 to take paper, the tray 11 will drive the paper to move up and move the topmost paper to a preset fixed paper taking position. Each time a paper is taken away, the number of corresponding papers will decrease. Accordingly, the tray 11 will drive the paper to rise one by one and rise to the preset fixed paper taking position.

[0039] If the high-level sensor 21 detects paper, it means that the amount of paper is sufficient and there is no need to add paper, and the system can continue to work. When the low-level sensor 22 detects that the position of the paper above has reached the minimum limit, it notifies the system that it needs to stop and add paper to the storage bin to increase the amount of paper buffer. Only when the amount of paper is between the positions of the high-level sensor 21 and the low-level sensor 22, the amount of paper buffer is qualified and the paper suction operation can continue.

[0040] like Figure 1-2 As shown, at least two monitoring components are provided for monitoring the tilt of the paper, which are used to monitor the tilt of the paper along its length direction and along its width direction respectively. Of course, there can be one or two monitoring components for monitoring the tilt of the paper along the same direction. All monitoring components for monitoring the tilt of the paper are arranged between the high position sensor 21 and the low position sensor 22 along the height direction of the stand 12. Because the height of the stacked paper will not exceed the upper and lower limits, if the height of the tilt of the paper exceeds the upper and lower limits, the position monitoring of the paper will have no guiding significance.

[0041] Furthermore, the monitoring components for monitoring the tilt of the paper are all located at non-central axis positions of the paper in the direction along the periphery of the paper. That is, all monitoring components for monitoring the tilt of the paper cannot be set on the central axis in the width or length direction of the paper. When the paper is tilted, monitoring the root of the central axis position cannot monitor whether the paper is tilted. Only when monitoring the non-central axis position in the length or width direction of the paper, that is, the position of its two side wings, can it be accurately determined whether the paper is tilted.

[0042] The monitoring components for monitoring the tilt of the paper in different directions are arranged adjacently on the different sides along the periphery of the paper, that is, the monitoring components for monitoring the tilt along the length direction of the paper and the monitoring components for monitoring the tilt along the width direction of the paper are arranged on different sides, and are arranged on adjacent stands 12. That is, the monitoring components for monitoring the tilt along the length direction of the paper are all arranged on the stands 12 arranged along the length direction of the paper; the monitoring components for monitoring the tilt along the width direction of the paper are all arranged on the stands 12 arranged along the width direction of the paper.

[0043] The monitoring components used to monitor the same tilt direction of the paper are staggered along the height direction of the stand on the same stand 12 or on the stand arranged in opposite positions. That is, the monitoring components used to monitor the tilt along the length direction of the paper are all constructed on the stand 12 arranged along the length direction of the paper. The monitoring components can be all arranged on the same stand 12 in the length direction, or on the stand 12 arranged in opposite positions in the length direction. For the monitoring components that monitor the tilt along the length of the paper, whether they are arranged on the same side stand or the stand arranged in opposite positions, their heights are different, that is, one is high and the other is low, so that the range of monitoring the tilt of the paper along its length direction can be expanded, and they cannot be arranged on the central axis of the length direction of the paper.

[0044] Correspondingly, the monitoring components for monitoring the tilting along the width direction of the paper are all arranged on the stand 12 arranged along the width direction of the paper. The monitoring components can be arranged on the same stand 12 arranged along the width direction of the paper, or on the counter stand 12 arranged along the width direction of the paper. The height position of the monitoring components for monitoring the tilting of the width of the paper has a certain height difference, that is, the height is staggered, and the monitoring components cannot be arranged on the central axis of the width direction of the paper in order to expand the range of monitoring the tilting of the paper along its width direction.

[0045] like Figure 2 As shown, there are only two monitoring components for monitoring the inclination of paper, namely, monitoring component 1 23 for monitoring the inclination of paper length and monitoring component 2 24 for monitoring the inclination of paper width. Monitoring component 1 23 is arranged on the outer wall surface of one of the stands 12 arranged along the length direction of paper, and monitoring component 2 24 is arranged on the outer wall surface of one of the stands 12 arranged along the width direction of paper, and the position heights of monitoring component 1 23 and monitoring component 2 24 are both located between the high position sensor 21 and the low position sensor 22. Among them, the height positions of monitoring component 1 23 and monitoring component 2 24 can be arranged at the same height or staggered, which is not specifically limited here and can be determined based on actual conditions, all within the protection scope of this case.

[0046] like Figure 1As shown, there are four monitoring components for monitoring the inclination of paper, namely, monitoring component 1 23 and monitoring component 3 25 for monitoring the inclination of paper length, and monitoring component 2 24 and monitoring component 4 26 for monitoring the inclination of paper width. Monitoring component 1 23 and monitoring component 3 25 are both arranged on the outer wall surface of the same stand 12 arranged along the length direction of paper, and the position height of monitoring component 1 23 is higher than the position height of monitoring component 3 25. Monitoring component 2 24 and monitoring component 4 26 are both arranged on the outer wall surface of the same stand 12 arranged along the width direction of paper, and the position height of monitoring component 2 24 is higher than the position height of monitoring component 4 26. The position heights of monitoring component 1 23, monitoring component 2 24, monitoring component 3 25 and monitoring component 4 26 are all located between the high position sensor 21 and the low position sensor 22. Preferably, the position heights of monitoring component 1 23 and monitoring component 2 24 are the same, and the position heights of monitoring component 3 25 and monitoring component 4 26 are the same, in order to ensure that the monitoring range of the inclination of paper length is consistent with the monitoring range of the inclination of paper width, so as to improve the consistency and stability of monitoring.

[0047] like Figure 3 As shown, the tray 11 is embedded in the groove 15 on the base 13 through four guide pillars, and the stand 12 is fixed to the base 13 through a connecting piece. A long hole 14 is provided on the bottom mounting surface of the stand 12, and a mounting hole matching the long hole 14 is provided on the base 13. The long holes 14 are all arranged along the length or width direction of the base 13. By adjusting the position of the long hole 14 on the alignment stand 12, the distance between the alignment stands 12 can be adjusted, so that paper of different width or length can be adapted, and then silicon wafers of different sizes and specifications can be loaded and packaged.

[0048] The tray 11 is constructed as an I-shaped structure and is provided with outwardly inclined wings at its four corners, wherein the inclination angle of the wing is 30-75°, preferably 45°. The wing can be placed as a guide card in the gap between the uprights 12, and its strength and stability in supporting the paper can be adjusted based on the different sizes of paper, and it can also be positioned along the gaps between the four uprights 12.

[0049] In order to ensure the stability of the lifting and lowering of the packaging tray 11 , a groove 15 adapted to the structure of the tray 11 is provided on the base 13 , and the groove 15 is adapted to the structure of the tray 11 .

[0050] When any monitoring device detects that the paper is tilted, the monitor will transmit the information to the system. The system will directly determine that the paper is tilted, immediately notify the paper feeding mechanism to stop, manually assist in straightening the paper, and then notify the system to reset and continue the paper picking or feeding operation.

[0051] The paper storage mechanism designed by the present application can monitor the tilt of the paper accurately and quickly to ensure the flatness of the paper and optimize the storage structure. It can be used to place paper of various sizes. It has a simple structure, is easy to install, and is safe and convenient to disassemble. The present application also proposes a packaging or unpacking device provided with the paper picking mechanism.

[0052] The above detailed description of the embodiments of the present application is only a preferred embodiment of the present application and cannot be considered to limit the scope of implementation of the present application. All equivalent changes and improvements made within the scope of the present application should still fall within the scope of the patent coverage of the present application.
