Description

Technical Field

[0001] The utility model belongs to the technical field of electrolytic aluminum, and in particular relates to a multifunctional terminal ferrophosphorus cleaning mechanism. Background Art

[0002] In the anode assembly workshop of an electrolytic aluminum production enterprise, there are still excess ferrophosphorus blocks on the surface of the cast anode carbon blocks. These ferrophosphorus blocks cannot be brought into the next production link and need to be cleaned. The current cleaning is mainly done by hammering the ferrophosphorus sheets with the air hammer at the end of the six-axis industrial robot, so that the ferrophosphorus sheets can be separated from the surface of the carbon block. Due to the limitations of the air hammer structure and the carbon block catenary system structure, the air hammer’s degree of freedom is not enough to completely cover the ferrophosphorus area, especially the overflowing ferrophosphorus sheets around the carbon bowl cannot be cleaned, so the ferrophosphorus sheets cannot be completely removed. The most critical problem is that due to the uneven thickness of the ferrophosphorus, the force of the air hammer is also uneven, which increases the difficulty of teaching the robot's movements. At the same time, there is also a continuous impact reaction force on the robot structure itself, which has an adverse effect on the normal operation of the entire robot workstation system.

[0007] The floating base is connected to the angle grinder body through a fixed bracket, the rotating shaft of the angle grinder body is connected to the vibration wheel, the outer ring of the rotating shaft seat of the angle grinder body is connected to the vibration bracket, the vibration bracket is connected to the bolt in the form of a thread, the bolt is axially provided with a thread section and a positioning section, the cross-sectional projection of the positioning section is smaller than the cross-sectional projection of the thread section and is located within the cross-sectional projection of the thread section;

[0008] The positioning section is plugged into the blade base, and the blade base is provided with a positioning hole adapted to the positioning section. The blade base is provided with a vibration cavity for cooperating with a vibration wheel, and the vibration wheel is located in the vibration cavity.

[0043] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0044] like Figure 1-7 As shown, a multifunctional terminal ferrophosphorus cleaning mechanism of the utility model comprises a frame 1 for providing a mounting surface;

[0045] The frame 1 is provided with a guide rail 2, which is slidably connected to a floating base 4. The outer ring of the guide rail 2 is sleeved with a compression spring 3. One end of the compression spring 3 abuts against the floating base 4, and the other end abuts against the frame 1. The movement of the floating base 4 along the axis direction of the guide rail 2 changes the compression amount of the compression spring 3.

[0046] The floating base 4 is connected to the angle grinder body 5 through a fixed bracket, the rotating shaft of the angle grinder body 5 is connected to the vibration wheel 7, the outer ring of the rotating shaft seat of the angle grinder body 5 is connected to the vibration bracket 6, the vibration bracket 6 is connected to the bolt 8 in the form of a thread, and the bolt 8 is provided with a thread section and a positioning section 81 along the axial direction, and the cross-sectional projection of the positioning section 81 is smaller than the cross-sectional projection of the thread section and is located within the cross-sectional projection of the thread section;

[0047] The positioning section 81 is plugged into the blade base 9. The blade base 9 is provided with a positioning hole 92 adapted to the positioning section 81. The blade base 9 is provided with a vibration cavity 91 for cooperating with the vibration wheel 7. The vibration wheel 7 is located in the vibration cavity 91. The vibration wheel 7 hits the cavity wall of the vibration cavity 91 when rotating. A vibration column 93 is provided on the surface of the blade base 9. The vibration column 93 of the blade base 9 is plugged into the semicircular blade 10. The vibration column 93 transmits the vibration impact from the vibration wheel 7 to the semicircular blade 10.

[0048] In this embodiment:

[0049] A multifunctional terminal ferrophosphorus cleaning mechanism of the utility model is installed at the operating end of the robot body 18, and realizes position transfer under the drive of the robot body 18. The robot body 18 carries the semicircular scraper 1 to peel off the ferrophosphorus sheets on the carbon block in a motion trajectory set by the program. The peeling action includes the radial pressure provided by the motion direction of the robot body 18 and the axial pressure provided by the inclined surface of the semicircular scraper 1. Under the action of these two forces, the ferrophosphorus sheets will be separated from the surface of the carbon block;

[0050] Under the elastic force of the compression spring 3, the floating base 4 moves along the axial direction of the guide rail 2, and the blade surface of the semicircular scraper 10 contacts the surface of the carbon block, generating a reaction force for balancing the elastic force. The reaction force presses the semicircular scraper 10 and the scraper base 9 at the step transition of the bolt 8. The bolt 8 is axially provided with a threaded section and a positioning section 81. The positioning section 81 is smaller than the threaded section, and a limit step is formed at the junction of the threaded section and the positioning section 81. In order to adapt to the change in the thickness of the ferrophosphorus, the compression spring 3, the floating base 4 and the guide rail 2 ensure that the blade surface of the semicircular scraper 1 is in close contact with the surface of the carbon block. Because when the thickness of the ferrophosphorus changes, the compression spring 3 will be compressed or reset, so that the position of the floating base 4 and the semicircular scraper 10 is adaptively changed;

[0051] The semicircular scraper 10 realizes the stripping of the ferrophosphorus sheet on the carbon block by high-frequency vibration. The specific vibration transmission is as follows: the rotating shaft of the angle grinder body 5 rotates, thereby driving the vibration wheel 7 to hit the vibration cavity 91 of the scraper base 9, forcing the scraper base 9 to vibrate, and the vibration column 93 of the scraper base 9 transmits the vibration to the semicircular scraper 10, so that the semicircular scraper 10 follows the vibration;

[0052] In summary, the utility model 1. scrapes the ferrophosphorus sheets by means of high-frequency vibration of the semicircular scraper 10, thereby solving the problem of the scraping angle and the scraping area fully covering the surface of the carbon block; 2. while the semicircular scraper 10 vibrates at a high frequency, it has an up and down floating function, which can ensure that the contact force between the semicircular scraper 10 and the surface of the carbon block is uniform, fundamentally eliminating the unfavorable factors of the robot motion program teaching.

[0053] Preferably, the cross-sectional shape of the positioning segment 81 is composed of a major arc and a chord connecting the two end points of the major arc. With such a structural design, the plane where the chord connecting the two end points of the major arc lies limits the rotational freedom of the blade base 9. In fact, other structural shapes of the positioning segment 81 can also be considered according to specific circumstances.

[0054] Preferably, the semicircular scraper 10 is provided with a plug hole 101 that is plugged into the vibration column 93. With such a structural design, the plug hole 101 is used to achieve the connection between the semicircular scraper 10 and the vibration column 93 and receive the vibration of the vibration column 93. In fact, other structural shapes for the semicircular scraper 10 to cooperate with the vibration column 93 can also be considered according to specific circumstances.

[0055] Preferably, it also includes a motor 11 and a steel brush roller 13, wherein the motor 11 is fixedly connected to the frame 1, and the steel brush roller 13 is rotatably connected to the frame 1, and the output end of the motor 11 is connected to the rotating end of the steel brush roller 13 through a coupling 12. With such a structural design, the coupling 12 transmits the torque of the motor 11 to the steel brush roller 13, driving the steel brush roller 13 to rotate, thereby further cleaning the phosphorus iron flakes that have been separated from the carbon block and still remain on the surface of the carbon block, thereby integrating the stripping of the phosphorus iron flakes with the cleaning function, and improving the phosphorus iron cleaning efficiency. In fact, other cleaning structures can also be considered according to specific circumstances.

[0056] Preferably, the frame 1 is further connected to a flange 15, which is located between the steel brush roller 13 and the angle grinder body 5. With this structural design, the flange 15 is used to achieve connection with the robot body 18, and the flange 15 is located between the steel brush roller 13 and the angle grinder body 5, so that the steel brush roller 13 and the angle grinder body 5 can be prevented from interfering with each other due to being too close to each other. In fact, other structural shapes that can avoid interference due to being too close in space can also be considered according to specific circumstances.

[0057] Preferably, the frame 1 is connected to a guard plate 14 for protecting the guide rail 2, the compression spring 3, the floating base 4, and the motor 11. With such a structural design, the guard plate 14 is used to provide protection to prevent people or objects in the external environment from interfering with or damaging the guide rail 2, the compression spring 3, the floating base 4, and the motor 11. In fact, other protective structures can also be considered according to specific circumstances.

[0058] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
