Description

Technical Field

[0001] The utility model belongs to the technical field of trough-type cleaning equipment for solar cell production, and particularly relates to a basket-carrying cantilever-type manipulator. Background Art

[0002] With the increasing global demand for renewable energy, the solar photovoltaic industry has experienced rapid growth. During the solar cell manufacturing process, silicon wafers undergo cleaning, diffusion, annealing, coating, and screen printing. This cleaning process typically utilizes tank-type cleaning equipment. Silicon wafers are placed in a basket, which is then moved through various process tanks by a cantilevered robotic arm.

[0003] The cantilever robot mainly consists of a column and a horizontal arm perpendicular to the column. One end of the horizontal arm is rotatably connected to the column through bolts and a rotating shaft. The other end of the cantilever is used to extract the flower basket. However, as the equipment production capacity continues to increase, the number of flower baskets and silicon wafers driven by the robot is also increasing. Especially after long-term high-frequency work, the connecting bolts of the robot's horizontal arm loosen, causing the horizontal arm to sag. It is necessary to stop the machine for manual tightening, which affects production efficiency. If the tightening is not timely, it may also cause the basket to be crushed, break, and collide with the machine.

[0004] The utility model patent with application number CN221391046U discloses a cantilevered manipulator and cleaning equipment, and proposes adding an adjustment component behind the manipulator cantilever and using a support bolt to support the manipulator cantilever to prevent it from sagging. Although this solution can prevent it from sagging to a certain extent, the support bolt still becomes loose after a period of use, and cannot completely solve the problem.

[0005] Therefore, in order to solve the technical problem of how to prevent the cross arm of the manipulator from sagging, it is urgent to provide a cantilever manipulator.

[0006] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them.

[0044] Research has found the shortcomings of the existing technology: the cantilever manipulator mainly includes a column and a horizontal arm perpendicular to the column. One end of the horizontal arm is rotatably connected to the column through bolts and a rotating shaft, and the other end of the cantilever is used to extract the flower basket. However, as the production capacity of the equipment continues to increase, the number of flower baskets and silicon wafers driven by the manipulator is also increasing. Especially after long-term high-frequency work, the connecting bolts of the manipulator horizontal arm loosen, causing the horizontal arm to sag, and the machine needs to be stopped for manual tightening, affecting production efficiency. If the tightening is not timely, it may also cause the basket to be crushed, break, and collide with the machine.

[0045] The utility model patent with application number CN221391046U discloses a cantilevered manipulator and cleaning equipment, and proposes adding an adjustment component behind the manipulator cantilever and using a support bolt to support the manipulator cantilever to prevent it from sagging. Although this solution can prevent it from sagging to a certain extent, the support bolt still becomes loose after a period of use, and cannot completely solve the problem.

[0046] Therefore, in order to solve the technical problem of how to prevent the cross arm of the manipulator from sagging, it is urgent to provide a cantilever manipulator.

[0047] The defects in the above solutions are the results obtained by the utility model inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article should be the contributions made by the utility model inventor to the present invention during the disclosure process.

[0048] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe the technical content.

[0049] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0050] See Figure 1 and Figure 2At least one embodiment provides a basket cantilever manipulator, comprising: a cross arm 1 and a column 2; wherein the column 2 is provided with a pair of rotating shafts 4; and the arm plates 3 on both sides of the cross arm 1 are rotatably connected to the column 2 through the corresponding rotating shafts 4. The cross arm 1 is provided with a limiting groove 7; the limiting groove 7 fixes the cross arm 1 to the column 2 through a limiting bolt 8, and the cross arm 1 is suitable for rotating around the rotating shaft 4. The limiting groove 7 and the limiting bolt 8 cooperate to limit the rotation angle of the cross arm 1. The cross arm 1 rotates around the rotating shaft 4 to adjust the angle of the cross arm 1 relative to the column 2 until the cross arm 1 is perpendicular to the column 2. At this time, the cross arm 1 is in a horizontal state, and the cross arm 1 is limited by screwing the limiting bolt 8 to prevent the cross arm 1 from sagging away from one end of the column 2. A reinforcement component 5 and a limiting block 6 are also provided on the column 2; two limiting blocks 6 correspond to the two arm plates 3 respectively. The limit block 6 is wedge-shaped, with a sloped front surface that abuts against the lower rear slope of the arm plate 3, and the back surface of the limit block 6 abuts against the reinforcement component 5 to limit the arm plate 3 from rotating around the rotation axis 4. The limit block 6 can be placed in different positions according to the angle adjustment of the cross arm 1, but no matter what position, the front surface of the limit block 6 always abuts against the lower rear slope of the arm plate 3, and the back surface always abuts against the reinforcement component 5. The end of the cross arm 1 away from the column 2 is subject to the weight of the vehicle for a long time, which can easily cause the cross arm 1 to sag. The arm plates 3 on both sides of the cross arm 1 are rotatably connected to the column 2 through the rotation axis 4. The sagging of the cross arm 1 causes the lower part of the arm plate 3 to rotate counterclockwise around the rotation axis 4. The reinforcement component 5 cooperates with the limit block 6 to limit the arm plate 3, preventing the arm plate 3 from rotating counterclockwise around the rotation axis 4, thereby preventing the arm plate 1 from sagging, thereby enhancing the stability of the manipulator.

[0051] In some embodiments, see Figures 1 to 3 The reinforcement assembly 5 includes: a fixed plate 51, on which a pair of adjustment slots 52 are provided. The end surface of the fixed plate 51 close to the column 2 abuts against the back of the limit block 6. An adjusting bolt 53 is threadedly connected to the column 2 and passes through the adjustment slot 52 to fix the fixed plate 51 on the column 2. When the adjusting bolt 53 is loosened, the fixed plate 51 can move up and down through the adjustment slot 52 until the end surface of the fixed plate 51 close to the column 2 covers the back of the limit block 6. At this time, the adjusting bolt 53 is tightened to limit the fixed plate 51. A fixed top screw plate 54 is located below the fixed plate 51 and is fixed to the column 2 by bolts. A pair of bolt holes are provided on the lower end surface of the fixed top screw plate 54, and the bolt holes pass through the fixed top screw plate 54; a fixed top screw 55 is threadedly adapted to the bolt holes of the fixed top screw plate 54, and the length of the fixed top screw 55 is greater than the height of the fixed top screw plate 54. The fixed top screw 55 is screwed to pass through the fixed top screw plate 54 and abut against the lower end surface of the fixed plate 51. The fixed top screw 55 and the fixed top screw plate 54 cooperate to support the fixed plate 51 to prevent the fixed plate 51 from sliding down.

[0052] In some embodiments, see Figures 4 to 6The cross arm 1 is provided with a plurality of hanging plates 9, on which a plurality of hooks 10 are provided, and the hooks 10 are suitable for hanging carriers 11. Optionally, the carrier can be a flower basket suitable for placing silicon wafers, and the flower basket is driven by a cantilever manipulator to clean the silicon wafers in each process tank.

[0053] See also Figure 1 Some embodiments further provide a basket cantilever manipulator, comprising: a cross arm 1, with arm plates 3 on both sides thereof rotatably connected to a column 2 via corresponding rotating shafts 4. A column 2, on which a limit block 6 is fixedly provided; two limit blocks 6, corresponding to the two arm plates 3 respectively. The limit block 6 is wedge-shaped, and its front surface is an inclined surface that abuts against the lower rear inclined surface of the arm plate 3. Optionally, the limit block 6 can be welded and fixed to the column 2. The drooping of the cross arm 1 causes the lower part of the arm plate 3 to rotate counterclockwise around the rotating shaft 4, and the limit block 6 welded to the column 2 abuts against the lower rear inclined surface of the arm plate 3 to limit the arm plate 3 from rotating counterclockwise around the rotating shaft 4, thereby preventing the cross arm 1 from sagging.

[0054] In summary, this embodiment provides a basket cantilever manipulator, which provides a limit block 6 and a reinforcement assembly 5. The fixed plate 51 in the reinforcement assembly 5 abuts against the back of the limit block 6, and the front of the two limit blocks 6 abuts against the lower rear inclined surfaces of the arm plates 3 on both sides of the cross arm 1 to limit the arm plates 3 and prevent them from rotating counterclockwise around the rotating shaft 4, thereby preventing the cross arm 1 from sagging. Furthermore, a fixed top screw plate 54 and a fixed top screw 55 are provided below the fixed plate 51. The fixed top screw 55 passes through the fixed top screw plate 54 and abuts against the lower end surface of the fixed plate 51 to prevent the fixed plate 51 from sliding down, thereby playing a multi-directional reinforcement role.

[0055] Compared with the prior art, the utility model patent with application number CN221391046U discloses a cantilever manipulator and cleaning equipment, which uses a top bolt to support the cantilever of the manipulator to prevent it from sagging. Although this solution can prevent the cross arm from sagging to a certain extent, the top bolt is in direct contact with the arm plate, and the force-bearing surface of the arm plate is small, which is easy to deform and damage. Moreover, the top bolt will become loose if it is compressed by the cross arm and the arm plate for a long time, and there is still a risk of the cross arm sagging. In this embodiment, a cantilever manipulator with a basket is provided, in which the limit block 6 is in surface-to-surface contact with the arm plate 3 and the fixing plate 51, and the force-bearing surface is wide, which is more firm.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0057] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0058] Spatially relative terms, such as "inside," "outside," "below," "beneath," "down," "above," "on," etc., may be used herein to describe the relationship of one element or feature to another element or feature as illustrated in the figures. In addition to the orientations depicted in the figures, spatially relative terms may be intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as being "below" or "below" other elements or features will be oriented to be "above" the other elements or features. Thus, the example term "below" may encompass both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0059] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention.
