Description

Technical Field

[0001] The present application relates to the technical field of flip shaft protection, and in particular to a copper sleeve for a flip shaft of a full basket flip mechanism. Background Art

[0002] Silicon wafers are commonly used raw materials in the photovoltaic field. After the silicon rods are cut into silicon wafers, there are silicon material impurities on the surface of the silicon wafers. In order to keep the surface of the silicon wafers clean, the silicon wafers are generally cleaned by a silicon wafer cleaning machine. When cleaning the silicon wafers, multiple silicon wafers are generally inserted into a flower basket through a wafer inserter, and the silicon wafers are placed in the silicon wafer cleaning machine through the flower basket for cleaning.

[0003] When the flower basket is in the conveying state, the flower basket is generally in a horizontal state, and when the flower basket is in the inserting state, it is generally in a vertical state. When the flower basket is flipped between the horizontal state and the vertical state, in order to facilitate the flipping of the flower basket, the flower basket is generally fixed on the flip shaft, and the two ends of the flip shaft are matched with the frame for rotation.

[0004] When the flower basket is flipped by the flip shaft, in order to reduce the wear of the flip shaft during frequent flipping, a copper sleeve is generally embedded in the frame. The copper sleeve is arranged in a circular ring shape, and the end of the flip shaft is inserted into the copper sleeve. The flip shaft and the copper sleeve rotate in coordination, and the flip shaft is protected and positioned by the copper sleeve.

[0005] The copper sleeve is prone to wear during long-term operation. In order to ensure the stability of the flower basket during the flipping process, the copper sleeve is generally replaced regularly. However, the existing copper sleeve is generally embedded in the frame, which has the defect of being inconvenient to install and replace the copper sleeve. Utility Model Content

[0032] The following is combined with Figure 1-Figure 7This application is described in further detail.

[0033] The embodiment of the present application discloses a copper sleeve for a turning shaft of a full basket turning mechanism.

[0034] Example 1

[0035] A copper sleeve for a turning shaft of a full basket turning mechanism comprises a mounting tube 2 and a mounting seat 3. The mounting seat 3 comprises a positioning portion 31 and a connecting portion 32, and the mounting tube 2 is fixedly mounted on the positioning portion 31. A mounting hole 11 is provided on a frame 1, and the mounting tube 2 is located inside the mounting hole 11. The connecting portion 32 mounts the mounting tube 2 inside the mounting hole 11 through the positioning portion 31.

[0036] When installing the copper sleeve, the installation tube 2 is inserted into the installation hole 11, and the connection part 32 fixes the installation tube 2 in the installation hole 11 through the positioning part 31, and the end of the flip shaft 4 is located in the installation tube 2, so that the flip shaft 4 and the installation tube 2 are rotatably matched. When the copper sleeve needs to be removed, the connection part 32 is disconnected from the installation tube 2 and the frame 1 through the positioning part 31, thereby improving the convenience of replacing the copper sleeve.

[0037] The positioning portion 31 includes a positioning ring. The positioning ring is coaxial with the mounting tube 2, and the inner wall of the positioning ring is connected to the outer wall of the mounting tube 2, and the end face of the positioning ring is flush with the end face of the mounting tube 2. After the end of the mounting tube 2 away from the positioning ring is inserted into the mounting hole 11, the side wall of the positioning ring is in contact with the frame 1, so that the mounting tube 2 is positioned.

[0038] The length of the mounting tube 2 is longer than the width of the frame wall of the frame 1. When the flip shaft 4 is placed inside the mounting tube 2, there is a larger contact area between the flip shaft 4 and the mounting tube 2. When the flip shaft 4 is working, the working stability of the flip shaft 4 is further improved.

[0039] The frame 1 is provided with a plurality of first connection holes 12, which are evenly distributed along the axial direction of the mounting hole 11. In the embodiment of the present application, there are four first connection holes 12. The side wall of the positioning ring is provided with a plurality of second connection holes 311, which are evenly distributed along the axial direction of the positioning ring. In the embodiment of the present application, there are four second connection holes 311, each of which is a through hole, and the four first connection holes 12 correspond to the four second connection holes 311 one by one.

[0040] The connecting portion 32 includes a plurality of connecting bolts. In the embodiment of the present application, four connecting bolts are provided, and the four connecting bolts correspond to the four second connecting holes 311 one by one, and each connecting bolt passes through the corresponding second connecting hole 311 , and each connecting bolt is threadedly connected to the corresponding first connecting hole 12 .

[0041] The implementation principle of a copper sleeve for a flipping shaft of a full basket flipping mechanism according to an embodiment of the present application is as follows: when installing the copper sleeve, the mounting tube 2 is inserted into the mounting hole 11, and the end of the flipping shaft 4 is located inside the mounting tube 2, so that the positioning ring and the side wall are in conflict with the side wall of the frame 1, and then, the connecting bolt is passed through the corresponding second connecting hole 311, and the connecting bolt is threadedly connected to the frame 1 through the corresponding first connecting hole 12, so that the mounting tube 2 is fixedly installed in the mounting hole 11; when the copper sleeve needs to be replaced, the connecting bolt is screwed to disconnect the connection between the connecting bolt and the frame 1, and the mounting tube 2 can be pulled out through the positioning ring, thereby improving the convenience of installing and removing the copper sleeve.

[0042] Example 2

[0043] The difference between this embodiment and embodiment 1 is that a plurality of guide grooves 21 are provided on the outer circumferential surface of the installation tube 2 along the axial direction of the installation tube 2, and each guide groove 21 penetrates the end of the installation tube 2 close to the positioning ring. In the embodiment of the present application, four guide grooves 21 are provided, and the four guide grooves 21 are evenly distributed circumferentially along the axial direction of the installation tube 2. A limiting hole 22 is provided on the inner wall of each guide groove 21 close to the axial direction of the installation tube 2.

[0044] A guide hole 312 is formed on the inner wall of each second connection hole 311 toward the axis of the positioning ring, and the four guide holes 312 correspond to the four limiting holes 22 one by one.

[0045] The limiting portion 33 includes a limiting rod, which can be a square rod or a round rod. In the embodiment of the present application, the limiting rod is a round rod. The limiting rod and the guide hole 312 are slidably matched, and the limiting rod and the limiting hole 22 are plug-fitted. In order to facilitate the insertion of the limiting rod into the limiting hole 22, a chamfer is provided on one end of the limiting rod close to the positioning tube.

[0046] An arc surface is provided at one end of the limiting rod away from the positioning cylinder. After the limiting rod is inserted into the limiting hole 22, the arc surface at the end of the limiting rod away from the positioning cylinder is coaxial with the inner wall of the corresponding second connecting hole 311, and the radius of the arc surface is consistent with the radius of the corresponding second connecting hole 311.

[0047] The implementation principle of Example 2 is as follows: when installing the copper sleeve, the installation tube 2 is inserted into the positioning ring, the installation tube 2 is initially positioned through the inner ring wall of the positioning ring, and the limiting rod is inserted into the guide hole 312, and the installation tube 2 and the positioning ring are rotated relatively, and the limiting rod falls into the guide groove 21. The inner wall of the guide groove 21 further limits the positioning ring through the limiting rod, and then, the installation tube 2 is further inserted into the positioning ring. During the insertion of the installation tube 2, the positioning ring drives the limiting rod to slide inside the guide groove 21. When the limiting rod moves to the limiting hole 22, the limiting rod is inserted into the limiting hole 22, and then, the connecting bolt is inserted into the second connecting hole 311, so that the connecting bolt limits the limiting rod, thereby improving the stability of the connection between the installation tube 2 and the positioning ring; when the installation tube 2 needs to be replaced, after the connecting bolt is pulled out of the second connecting hole 311, the limiting rod is poured out from the guide hole 312, so as to disconnect the connection between the installation tube 2 and the positioning ring, thereby improving the convenience of replacing the installation tube 2.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
