Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of silicon wafer production, and particularly relates to a robotic arm hanging plate with an anti-floating mechanism. Background Technique
[0002] The alkali polishing process of silicon wafers is a key step in the production process of solar modules. Its main purpose is to improve the photoelectric conversion efficiency of the modules, reduce the power generation cost, and enhance the anti-pollution performance of the silicon wafers.
[0003] The principle of the alkali polishing process is to chemically treat the surface of the battery wafers with an alkaline solution, remove the surface impurities and oxide layers through chemical reactions, make the surface of the battery wafers smoother and cleaner, and facilitate the absorption and conversion of light.
[0004] In the alkali polishing process, the robotic arm drives the carrier basket containing silicon wafers to move through the hanging plate, so as to put the carrier basket into or take it out of the tank. The connecting mechanism on the hanging plate needs to be docked with the designated position of the carrier basket to connect to the carrier basket. Moreover, the hanging plate is liftable. Thus, when the docking position between the hanging plate and the carrier basket is incorrect, the hanging plate has a certain upward movement space to avoid damage to the hanging plate or the carrier basket. However, a problem arises at this time, that is, after the hanging plate extends into the tank, the liquid in the tank will apply an upward force to the hanging plate, so that the hanging plate will move upward, and further, when the hanging plate is correctly docked with the carrier basket, the proximity sensor can still detect the hanging plate, and the robotic arm is controlled to stop working through the controller. At this time, manual intervention is required, which affects the efficiency. Content of the Utility Model
[0005] The main purpose of the utility model is to provide a robotic arm hanging plate with an anti-floating mechanism. The elastic component applies a downward pressure to the hanging plate. After the hanging plate enters the tank under the action of the robotic arm, the hanging plate will be subjected to an upward force due to contact with the liquid in the tank. At this time, the upward force received by the hanging plate cannot overcome the downward pressure applied by the elastic component to the hanging plate, so the hanging plate will not move upward, and further ensure that the proximity sensor cannot detect the hanging plate in this state, so that the robotic arm can drive this mechanism to move normally.
[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0007] A robotic arm hanging plate with an anti-floating mechanism, including a connecting piece and a hanging plate. The hanging plate is connected to the connecting piece through at least two groups of connecting components so as to be able to move up and down. A proximity sensor for detecting the position of the hanging plate is fixed on one side of the hanging plate. An elastic component is further arranged on one side of the connecting piece. The elastic component presses down the hanging plate to prevent the hanging plate from floating upward due to the buoyancy of the liquid in the tank.
[0008] Further, the elastic component includes a fixing piece, and a spring piece is connected to the bottom of the fixing piece.
[0009] Further, the proximity sensor is fixed to the connecting member by a clamp, and the fixing member is connected to the clamp by a screw.
[0010] Further, the connection assembly includes a positioning plate fixed to one side of the connecting member and a positioning groove formed on the surface of the hanging plate. The positioning plate is located within the positioning groove, and a limiting plate is fixed to one end of the positioning plate and is located outside the positioning groove.
[0011] Further, a hanging rod is fixed to the bottom of one side of the hanging plate.
[0012] Further, a protrusion matching the proximity sensor is fixed to the top of the hanging plate.
[0013] Further, the elastic sheet is made of polypropylene material.
[0014] Compared with the prior art, the present utility model has the following beneficial effects:
[0015] The elastic component of the present utility model applies a downward pressure to the hanging plate. When the hanging plate enters the groove body under the action of the robotic arm, the hanging plate will receive an upward force due to contact with the liquid in the groove body. At this time, the upward force received by the hanging plate cannot overcome the downward pressure applied by the elastic component to the hanging plate, so the hanging plate will not move upward, thereby ensuring that the proximity sensor cannot detect the hanging plate in this state, so that the robotic arm can drive the mechanism to move normally.
[0016] The positioning plate of the present utility model cooperates with the connecting member to limit the positioning plate within the positioning groove, and the positioning plate can move up and down within the positioning groove. Therefore, the hanging plate can move up and down relative to the connecting member, so that there is a certain upward displacement space for the hanging plate when it descends and contacts the frame of the flower basket.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] As Figures 1-3 shown, a robotic arm hanging plate with an anti-floating mechanism includes a connecting member 1 and a hanging plate 2. The hanging plate 2 is connected to the connecting member 1 through at least two sets of connecting components 3 so as to be movable up and down. A proximity sensor 5 for detecting the position of the hanging plate 2 is fixed on one side of the hanging plate 2. An elastic component 6 is also arranged on one side of the connecting member 1. The elastic component 6 presses down the hanging plate 2 to prevent the hanging plate 2 from floating upward due to the buoyancy of the liquid in the tank.
[0023] In this embodiment, as Figure 1 and Figure 3 shown, the elastic component 6 includes a fixing member 601. A spring piece 602 is connected to the bottom of the fixing member 601. The spring piece 602 is made of polypropylene material. The spring piece 602 made of polypropylene is acid and alkali resistant, has good elasticity and a long service life. The proximity sensor 5 is fixed to the connecting member 1 through a clamp 7, and the fixing member 601 is connected to the clamp 7 through a screw.
[0024] The connecting member 1 is connected to the robotic arm. When the robotic arm drives this mechanism to reach the correct position in the tank, the hanging plate 2 will be subjected to an upward force due to contact with the liquid in the tank. At this time, since the end of the spring piece 602 presses down the hanging plate 2, and the upward force received by the hanging plate 2 cannot overcome the downward pressure exerted by the spring piece 602 on the hanging plate 2, the hanging plate 2 will not move upward, thereby ensuring that the proximity sensor 5 cannot detect the hanging plate 2, so that the robotic arm can normally drive this mechanism to move.
[0025] When the position where the robotic arm drives this mechanism to reach the tank is deviated, the hanging plate 2 will contact the frame of the flower basket. As the hanging plate 2 continues to descend, the frame of the flower basket will exert a reaction force on the hanging plate 2, so that the hanging plate 2 overcomes the force exerted by the spring piece 602 and moves upward, thereby enabling the proximity sensor 5 to detect the hanging plate 2, so as to transmit a signal to the controller to make the controller control the robotic arm to stop working (this is the prior art and will not be elaborated here too much), to avoid damage to the hanging plate 2 or the flower basket caused by the continued descent of this mechanism.
[0026] Among them, as Figure 1 and Figure 2As shown in the figure, the connecting component 3 includes a positioning plate 301 fixed to one side of the connecting piece 1 and a positioning groove 302 formed on the surface of the hanging plate 2. The positioning plate 301 is located within the positioning groove 302. One end of the positioning plate 301 is fixed with a limiting plate 303, and the limiting plate 303 is located outside the positioning groove 302. The limiting plate 303 cooperates with the connecting piece 1 to limit the positioning plate 301 within the positioning groove 302, and the positioning plate 301 can move up and down within the positioning groove 302. Therefore, the hanging plate 2 can move up and down relative to the connecting piece 1, so that when the hanging plate 2 descends to contact the frame of the flower basket, the hanging plate 2 has a certain upward displacement space.
[0027] Among them, as Figure 1 shown, a hanging rod 4 is fixedly installed at the bottom of one side of the hanging plate 2. When the robotic arm drives the mechanism to descend, when there is no deviation in the descending position, the hanging rod 4 will enter the L-shaped connecting groove of the flower basket. At this time, the robotic arm drives the mechanism to move horizontally, so that the hanging rod 4 enters the horizontal groove of the L-shaped connecting groove, and thus through the cooperation of multiple such mechanisms and the L-shaped connecting groove of the flower basket, the flower basket is moved up and down.
[0028] Among them, as Figure 1 shown, a protrusion 8 matching the proximity sensor 5 is fixed to the top of the hanging plate 2. When the hanging plate 2 moves up, it will drive the protrusion 8 to move up. The position of the protrusion 8 corresponds to the position of the proximity sensor 5. Therefore, the proximity sensor 5 can accurately detect the approach of the protrusion 8, thereby improving the detection accuracy.
[0029] Working principle: Connect multiple such mechanisms to the robotic arm through connecting pieces, and connect the proximity sensor to the controller. When the robotic arm drives the mechanism to probe down to the correct position in the groove, the hanging plate 2 will receive an upward force due to contact with the liquid in the groove. At this time, since the end of the elastic piece 602 presses down on the hanging plate 2, and the upward force received by the hanging plate 2 cannot overcome the downward pressure exerted by the elastic piece 602 on the hanging plate 2, the hanging plate 2 will not move upward. Furthermore, it is ensured that the proximity sensor 5 cannot detect the hanging plate 2, so that the robotic arm can normally drive the mechanism to move. When the position where the robotic arm drives the mechanism to probe down to the groove deviates, the hanging plate 2 will contact the frame of the flower basket. As the hanging plate 2 continues to descend, the frame of the flower basket will exert a reaction force on the hanging plate 2, so that the hanging plate 2 overcomes the force exerted by the elastic piece 602 and moves upward, and then the proximity sensor 5 can detect the hanging plate 2, so as to transmit a signal to the controller to make the controller control the robotic arm to stop working, avoiding damage to the hanging plate 2 or the flower basket caused by the continued descent of the mechanism.
