Technical Field
[0001] This utility model relates to the field of welding technology, specifically to an oxide film removal device. Background Technology
[0002] Welding, also known as fusion welding, is a manufacturing process and technology that combines metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure.
[0003] Modern welding utilizes a variety of energy sources, including gas flames, electric arcs, lasers, electromagnets, friction, and ultrasound. Besides its use in factories, welding can also be performed in diverse environments, such as outdoors, underwater, and in space.
[0004] Metals such as aluminum alloys are easily oxidized in containers, forming a hard and dense oxide film, such as aluminum oxide. The melting point of this oxide film is much higher than that of the base metal. During welding, if the oxide film is not removed, it is difficult to melt, thus hindering the transfer of molten metal droplets, affecting the fusion of the filler metal and the base metal, and potentially leading to incomplete fusion defects.
[0005] Therefore, to ensure welding quality, appropriate measures must be taken to remove the oxide film before welding. This is usually achieved through methods such as mechanical grinding, chemical cleaning, or flame burning. Current technology typically involves workers using handheld grinders to polish the surface of metals such as aluminum alloys to ensure welding quality. However, this requires workers to hold the grinder for extended periods, leading to high labor intensity. Furthermore, during manual grinding, aluminum shavings can easily enter the worker's body through the mouth and nose, potentially impacting their health.
[0006] Therefore, how to provide a method for automatically polishing the surfaces of metals such as aluminum alloys is a technical problem that urgently needs to be solved. Utility Model Content

Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0033] The oxide film removal device of this application can be applied to the removal of oxide films from bulk or plate-shaped metals, and can also be used in other similar applications. The oxide film removal device is described in detail below.
[0034] See appendix Figure 1 — Figure 9 The diagram shown illustrates a preferred embodiment of an oxide film removal device according to this application. The oxide film removal device includes a base frame 1, a grinding chamber 2 mounted on the base frame 1, a grinding assembly 3 mounted on the grinding chamber 2, a conveying assembly 4 mounted on the base frame 1, a clamping structure 5 mounted on the conveying assembly 4, and a dust collection assembly 6 mounted on the grinding chamber 2.
[0035] This invention utilizes a grinding component 3 to grind the surface of metal parts, removing the oxide film and improving the quality of subsequent welding. A conveying component 4 transports the metal parts into the grinding chamber 2 for oxide film removal. A clamping structure 5 holds the metal parts in place, preventing them from moving during the process of oxide film removal and thus preventing them from flying out of the grinding chamber 2. This ensures proper grinding of the metal parts and guarantees the safety of the equipment during operation.
[0036] See appendix Figure 8 and Figure 9 As shown, in this utility model, the dust collection component 6 includes a dust collection chamber 61 installed on the side of the grinding chamber 2, an air pump 62 installed on the top of the dust collection chamber 61, a dust baffle 63 installed on the dust collection chamber 61, and a dust collection frame 64 installed on the dust collection chamber 61; the air inlet of the air pump 62 is connected to the inside of the dust collection chamber 61; the dust baffle 63 is located between the air pump 62 and the dust collection frame 64.
[0037] This invention utilizes a dust collection chamber 61 to collect metal dust generated during the grinding of metal parts; an air pump 62 provides the power source for airflow, causing the gas in the grinding chamber 2 to move into the dust collection chamber 61, thus allowing the metal dust generated during the removal of the oxide film from the metal block to move into the dust collection chamber 61 for collection; a dust baffle 63 blocks the metal dust entering the dust collection chamber 61, preventing it from entering the air pump 62 with the airflow, thereby protecting the air pump 62 and extending its service life; and a dust collection frame 64 collects the metal dust entering the dust collection chamber 61 for subsequent unified processing.
[0038] See appendix Figure 6 and Figure 7 As shown, in this utility model, the grinding chamber 2 has a communicating groove 21 on its wall that communicates with the dust collection chamber 61, a sliding plate 22 that is movably installed in the communicating groove 21, a connecting plate 23 installed on the sliding plate 22, and a control cylinder 24 that is installed on the base frame 1 and connected to the connecting plate 23; the communicating groove 21 is located between the dust baffle 63 and the dust collection frame 64.
[0039] This invention utilizes a connecting slot 21 to connect the grinding chamber 2 and the dust collection chamber 61, allowing technical dust from the grinding chamber 2 to enter the dust collection chamber 61. The connecting slot 21 is positioned between the dust-blocking component 63 and the dust collection frame 64, ensuring that the dust-blocking component 63 can block metal dust while the dust collection frame 64 can collect it. A connecting plate 23 controls the opening and closing of the connecting slot 21. It should be noted that the connecting plate 23 is composed of two horizontal plates, one with a hole and the other with a post, the post and hole being interference-fitted. The connecting plate 23 connects the sliding plate 22 to the control cylinder 24, allowing the control cylinder 24 to move the sliding plate 22 up and down.
[0040] See appendix Figure 8 and Figure 9 As shown, in this utility model, the dust collection bin 61 is provided with a first disassembly groove 611 and a second disassembly groove 612, the dust blocking component 63 is movably installed in the first disassembly groove 611, and the dust collection frame 64 is installed in the second disassembly groove 612.
[0041] The present invention provides an installation position for the dust-blocking component 63 through the first disassembly groove 611, and allows the dust-blocking component 63 to be disassembled, cleaned or replaced; and provides an installation position for the dust collection frame 64 through the second disassembly groove 612, and allows the dust collection frame 64 to be disassembled for unified treatment of the collected metal dust.
[0042] See appendix Figure 8 and Figure 9 As shown, in this utility model, the dustproof component 63 includes a dustproof frame 631 movably installed in the first disassembly groove 611, a dustproof net 632 installed on the dustproof frame 631, a first handle 633 installed on the dustproof frame 631, and a first rubber strip 634 that contacts the first disassembly groove 611 is installed on the outer wall of the dustproof frame 631.
[0043] This utility model provides an installation position for the dust filter 632 through the dust filter frame 631; the dust filter 632 blocks metal dust and prevents it from entering the air pump 62; the first handle 633 facilitates the installation and removal of the dust filter frame 631 by the operator; and the first rubber strip 634 increases the friction between the dust filter frame 631 and the first disassembly groove 611, preventing the dust filter frame 631 from sliding out of the first disassembly groove 611.
[0044] See appendix Figure 8 and Figure 9 As shown, in this utility model, a second handle 641 is installed on the dust collection frame 64, and a second rubber strip 642 that contacts the second disassembly groove 612 is installed on the outer wall of the dust collection frame 64.
[0045] The present invention facilitates the installation and disassembly of the dust collection frame 64 by the provision of the second handle 641; and increases the friction between the dust collection frame 64 and the second disassembly groove 612 by the provision of the second rubber strip 642, preventing the dust collection frame 64 from sliding out of the second disassembly groove 612.
[0046] See appendix Figure 1 and Figure 2 As shown, in this utility model, the conveying assembly 4 includes a rodless cylinder 41 mounted on the base frame 1 and a placement plate 42 mounted on the rodless cylinder 41. The placement plate 42 is provided with a mounting groove 421, and a T-shaped block 422 for clamping structure 5 is installed in the mounting groove 421.
[0047] This invention provides a power source through the rodless cylinder 41, which drives the placement plate 42 to move, thereby moving the metal block on the placement plate 42. The placement plate 42 provides an installation position for the clamping structure 5 and the metal block. The installation groove 421 provides an installation position for the T-block 422 and provides conditions for the movement of the clamping plate 52. The T-block 422 provides an installation position for the clamping structure 5 and limits the movement of the clamping plate 52, preventing the clamping plate 52 from separating from the installation groove 421.
[0048] See appendix Figure 2 and Figure 3 As shown, in this utility model, the clamping structure 5 includes a clamping electromagnet 51 mounted on a T-block 422, a clamping plate 52 movably mounted on a mounting groove 421, a guide post 53 mounted on the clamping plate 52, a through hole 54 on the T-block 422 corresponding to the guide post 53, and a spring 55 fitted on the guide post 53.
[0049] This utility model uses a clamping electromagnet 51 to control the movement and clamping of the clamping plate 52; the clamping plate 52 is used to clamp the metal block; the guide post 53, in conjunction with the through hole 54, guides the movement of the clamping plate 52; and the spring 55 pushes the clamping plate 52 to move, ensuring that the clamping plate 52 can clamp the metal block.
[0050] See appendix Figure 3 As shown, in this utility model, the clamping plate 52 is H-shaped and is made of magnetic material; the two ends of the spring 55 are in contact with the clamping plate 52 and the T-block 422 respectively.
[0051] This invention ensures that the clamping plate 52 will not fall out of the mounting groove 421 and can only move along the mounting groove 421 by setting the clamping plate 52 to an H shape; the clamping plate 52 is made of magnetic material so that the clamping electromagnet 51 can control the movement of the clamping plate 52.
[0052] See appendix Figure 4 — Figure 6 As shown, in this utility model, the polishing assembly 3 includes a lifting cylinder 31 installed on the top of the polishing chamber 2, a U-shaped mounting bracket 32 installed on the lifting cylinder 31, a power source 33 installed on the side of the U-shaped mounting bracket 32, and a polishing roller 34 movably installed on the U-shaped mounting bracket 32 and connected to the power source 33.
[0053] This invention utilizes a lifting cylinder 31 as a power source to drive the U-shaped mounting bracket 32 to move up and down, thereby driving the polishing roller 34 to move up and down, allowing the polishing roller 34 to contact the surface of the metal block. The U-shaped mounting bracket 32 provides a mounting position for the power source 33 and the polishing roller 34. The power source 33 drives the polishing roller 34 to rotate. The polishing roller 34 can remove the oxide film from the surface of the metal block.
[0054] See appendix Figure 4 — Figure 6 As shown, in this utility model, the lifting cylinder 31 is connected to the middle position of the top of the grinding chamber 2; the power source 33 is a motor; the top of the C-shaped mounting bracket 32 is provided with multiple sliding rods 321; the top of the grinding chamber 2 is provided with sliding holes 25 corresponding to the sliding rods 321; a PLC controller 7 is installed on the base frame 1; and an infrared distance sensor 322 connected to the PLC controller 7 is provided on the C-shaped mounting bracket 32.
[0055] This utility model guides the lifting and lowering movement of the U-shaped mounting bracket 32 through the sliding rod 321 and the sliding hole 25; and monitors the distance between the U-shaped mounting bracket 32 and the base frame 1 through the setting of the infrared distance sensor 322, thereby controlling the moving distance of the telescopic rod of the lifting cylinder 31.
[0056] See appendix Figure 1 — Figure 9 As shown, the usage process of this utility model is as follows:
[0057] First, the operator controls the clamping electromagnet 51 to be energized via PLC controller 7. This generates a magnetic force between the clamping electromagnet 51 and the clamping plate 52, causing the clamping plate 52 to move towards the clamping electromagnet 51 until they are in close contact. The operator then places the metal block requiring oxide film removal in the center of the placement plate 42. After placement, the operator controls the clamping electromagnet 51 to be de-energized via PLC controller 7. At this point, spring 55 pushes the clamping plate 52 along the mounting groove 421 to clamp the metal block, ensuring it is positioned in the center of the placement plate 42. The operator then inputs the extension length of the lifting cylinder 31's telescopic rod via PLC controller 7. Subsequently, the operator begins removing the oxide film from the metal block via PLC controller 7, controlling the extension rod of the lifting cylinder 31 to extend until it reaches the designated position. Simultaneously, the PLC controller... The PLC controller 7 controls the power source 33 to start working, driving the polishing roller 34 to rotate. Then, the PLC controller 7 controls the rodless cylinder 41 to reciprocate. During the movement, the top surface of the metal block contacts the polishing roller 34, and the polishing roller 34 removes the oxide film. After the oxide film is removed, the operator controls the clamping electromagnet 51 to be energized through the PLC controller 7, so that the clamping electromagnet 51 is in contact with the clamping plate 52. The operator removes the metal block, completing the removal of the oxide film on the metal block, which can then be welded. It should be noted that when the PLC controller 7 controls the power source 33 to start working, the PLC controller 7 will also control the air pump 62 to start working and control the extension rod of the cylinder 24 to retract. After the oxide film is removed and all components are reset for a specified time, the PLC controller 7 will control the extension rod of the cylinder 24 to extend, driving the slide plate 22 to rise and closing the connecting groove 21. At the same time, the air pump 62 is turned off, and the metal dust begins to settle freely into the dust collection frame 64.
[0058] The above embodiments are illustrative of this application and are not intended to limit this application. Any simple modifications to this application are within the protection scope of this application.
