Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0033] Example 1:

[0034] like Figure 1-2 As shown, the utility model provides a technical solution:

[0035] A rubbing paper loading container, comprising a silo 1, a lifting plate 101 movable up and down is installed at the bottom of the silo 1, and a power device for driving the lifting plate 101 to move up and down is installed below the lifting plate 101;

[0036] The power device includes a ball screw 2, a motor 3 and a first synchronous belt mechanism 4. The motor 3 drives the ball screw 2 through the first synchronous belt mechanism 4. The slider on the ball screw 2 is connected to the lifting plate 101 to drive the lifting plate 101 to move up and down inside the silo 1; through the rotation of the ball screw 2, the silo 1 can be automatically lifted upward to facilitate the robot to grab the material.

[0037] The rubbing paper loading container in this embodiment integrates a vertically movable lifting plate 101 and a ball screw 2 power system driven by a motor 3, effectively achieving automatic lifting and feeding of the rubbing paper. This design effectively reduces the physical burden of rubbing paper while improving the speed and accuracy of rubbing paper feeding. The motor-driven automatic control system ensures an efficient circulation of rubbing paper within the silo 1, reducing the frequency of manual feeding and improving the automation and production efficiency of the entire rubbing process.

[0038] Example 2:

[0039] Based on Example 1, Figure 1-2 A plurality of brushes 5 are provided on the top of the silo 1, and the brush heads of the brushes 5 are facing the inner side of the silo 1; the brushes 5 can gently scrape the edge of the rubbing paper, so that the second piece of paper that may be adhered can be moved down and remain in the silo; when the robot absorbs the rubbing paper and leaves the silo, the edge of the paper passes through the brush, avoiding the adhesion of two pieces of rubbing paper on the upper and lower sides due to humid weather or electrostatic adsorption.

[0040] Furthermore, four brushes 5 are provided, and the four brushes 5 are symmetrically arranged on both sides of the silo 1 .

[0041] Furthermore, an optical fiber sensor 6 is installed on the top of the silo 1 to detect whether there is rubbing paper at the robot material taking position of the silo 1;

[0042] The motor 3 is a servo motor, and the rubbing paper is automatically fed upwards by the servo motor, which can ensure the smooth feeding action;

[0043] When the optical fiber sensor 6 detects that there is no rubbing paper, the servo motor drives the first synchronous belt mechanism 4 to rotate the ball screw 2 to lift the feed, and the optical fiber sensor 6 stops when it detects that there is rubbing paper.

[0044] Furthermore, two infrared sensing gratings are provided on the periphery of the silo 1. If someone puts his hand or body into this area during operation, an audible and visual alarm signal will be generated.

[0045] Furthermore, the first synchronous belt mechanism 4 includes a first protective cover and a first synchronous belt installed inside the first protective cover, and the first synchronous belt is connected to the ball screw 2 .

[0046] Furthermore, the rubbing papers in the silo 1 are put in by the operator, and more than or equal to 800 sheets of rubbing papers can be put in at one time.

[0047] On the basis of Example 1, Example 2 further introduces a brush 5 and a fiber optic sensor 6 on the top of the hopper 1; the setting of the brush 5 can effectively prevent the phenomenon of multiple sheets of rubbing paper sticking together due to problems such as static electricity or moisture, ensuring that only a single sheet of rubbing paper is taken each time, which directly improves the quality and accuracy of the rubbing operation; the use of the fiber optic sensor 6 further intelligentizes the entire paper supply process, and can monitor and adjust the position of the lifting plate in real time to ensure that the rubbing paper is always at the optimal access height, greatly enhancing the convenience and reliability of the operation.

[0048] Example 3:

[0049] like Figure 3-4 As shown, the utility model provides a technical solution:

[0050] An automatic feeding device for rubbing paper is provided, wherein the automatic feeding device for rubbing paper is provided with a rubbing paper loading container 7, and the rubbing paper loading container 7 adopts the aforementioned rubbing paper loading container.

[0051] Example 3 integrates the aforementioned rubbing paper loading container into a more comprehensive rubbing paper automatic feeding device, expanding the application range of the device. The automated design of the entire system effectively reduces the need for manual operation, reduces production costs, and improves the safety of the working environment.

[0052] Example 4:

[0053] Based on Example 3, Figure 3-4 ,

[0054] Furthermore, the automatic feeding device for rubbing paper further comprises a driving device 8 and a frame 10, wherein the driving device 8 is mounted in the middle of the frame 10;

[0055] There are two rubbing paper loading containers 7 , which are respectively installed on both sides of the driving device 8 . The driving device 8 is configured to drive the two rubbing paper loading containers 7 to move horizontally.

[0056] Furthermore, the driving device 8 includes a second protective cover and a rodless cylinder arranged inside the second protective cover; the use of the rodless cylinder to drive can ensure high-precision positioning of the start and end positions, making it easier for the robot to grab the rubbing paper stably;

[0057] Openings are provided on both sides of the second protective cover along the moving direction of the rubbing paper loading container 7, and a second synchronous belt mechanism 9 is provided near the opening in the second protective cover. The second synchronous belt mechanism 9 is connected to the rubbing paper loading container 7, and the rodless cylinder drives the second synchronous belt mechanism 9 to alternately feed the rubbing paper loading container 7; the two rubbing paper loading containers 7 are pushed and used alternately by the rodless cylinder, so that the robot material picking and manual feeding operations are separated.

[0058] Furthermore, a rubbing paper static removal and dehumidification device is provided on one side of the rubbing paper automatic feeding device to prevent the rubbing paper from sticking together; the rubbing paper static removal and dehumidification device here is specifically a heating and blowing device.

[0059] Example 4 incorporates a drive device 8 and a frame 10 equipped with two rubbing paper loading containers 7, enabling efficient bidirectional feeding. A second synchronous belt mechanism 9, precisely controlled by a rodless cylinder, enables alternating use of the two rubbing paper loading containers. This not only improves the paper supply stability of the feeding system but also ensures uninterrupted paper supply during continuous production, significantly enhancing production efficiency and system reliability. Furthermore, the addition of an air blower effectively addresses the problem of rubbing paper sticking due to environmental factors, ensuring consistent rubbing quality.
