Description

Technical Field

[0001] The present invention belongs to the technical field related to copper and aluminum plate grinding, and more specifically, relates to a precision surface grinding device for copper and aluminum plate production. Background Art

[0002] With the growing demand for copper and aluminum plate materials in the power, electronics, rail transportation and other industries, the requirements for dimensional accuracy and surface finish of the materials are becoming increasingly higher. Traditional manual polishing methods are difficult to meet high-precision requirements, easily resulting in material waste and poor consistency. Therefore, the development of precision polishing equipment can significantly improve material utilization and ensure processing accuracy. However, the copper and aluminum plate production and polishing devices in the existing technology have the following defects:

[0003] In existing technology, copper and aluminum plate production and polishing equipment typically produces a large amount of water-gouache mixture. If impurities in this mixture enter the polishing interface of the copper and aluminum plates, it may affect their surface roughness. The presence of large amounts of water-gouache mixture in copper and aluminum plate production and polishing equipment can affect the normal operation of the polishing equipment and reduce processing accuracy. For example, the mixture may adhere to the polishing tool or the copper and aluminum plate surface, affecting the polishing effect and even causing surface defects such as scratches and pits.

[0004] Existing copper and aluminum plate production and polishing equipment typically generates heat. While copper and aluminum have good thermal conductivity, overheating can cause microstructural changes, such as grain growth, which can affect the material's mechanical properties (such as strength and ductility) and electrical conductivity. For copper or aluminum foil used in the electronics industry, this can severely impact the performance of the final product.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention provides a precision surface polishing device for copper and aluminum plate production. The device is equipped with an extrusion water collection chamber. When the rotary motor starts rotating, it first drives the central gear, which in turn drives the polishing devices on both sides to move. Simultaneously, the drive motor is also started, driving the third rotating shaft to rotate, which in turn drives the conveyor belt for transmission. Subsequently, the copper and aluminum plates are placed on the surface of the conveyor belt and driven into the interior of the device to contact the drive device. During the movement of the polishing device, the drive gear shaft and the central gear cooperate to rotate, causing the second connecting shaft to rotate and driving the first connecting shaft to swing. The swinging of the first connecting shaft drives the piston plate to reciprocate, and the reciprocating motion of the piston plate further drives the piston push plate to squeeze the water collection chamber. After the water collection chamber is squeezed, the cooling water inside is squeezed out and transported to the inside of the circular nozzle through a drain pipe. Finally, water is sprayed out through the drain port to cool the copper and aluminum plates, preventing deformation of the copper and aluminum plates during processing. The movement of the polishing device can effectively polish the copper and aluminum plates and improve their surface quality. This is especially important for the processing of copper and aluminum plates that require high precision and high surface quality. Through the operation of the cooling water system, the copper and aluminum plates can be cooled during the processing process, which not only prevents the deformation of the copper and aluminum plates caused by the increase in temperature, but also extends the service life of equipment and tools.

[0020] The present invention provides a precision surface polishing device for copper and aluminum plate production. The device is provided with an ash-collecting scraper. When the driving gear shaft starts to rotate, it drives the polishing plate to rotate synchronously. Once the polishing plate contacts the copper and aluminum plates, it begins to polish them. During this polishing process, a large amount of water-gouache mixture is generated on the surface of the copper and aluminum plates. In order to collect this water-gouache mixture, the ash-collecting scraper plays a key role when rotating. The first scraper and the second scraper on the ash-collecting scraper work together. The first scraper is designed to be shorter than the second scraper, so that the water-gouache mixture can enter the space between the two through the opening gap of the first scraper. When the water-gouache mixture enters the area between the two, it will first be collected by the lower baffle plate through rotation and then the rotation acts again to adsorb the water-gouache mixture onto the baffle plate set on the upper side. On these two baffle plates, the water-gouache mixture will be effectively intercepted and effectively filtered by the design of the oblique flow channel. The design of the ash-collecting scraper solves the problem of collecting the water-gouache mixture generated during the polishing process. The collaboration between the first and second scrapers, along with the unique opening of the first scraper, allows the water-powder mixture to flow smoothly into the space between the dust-collecting scraper and the baffle plate, preventing splashing and scattering of the mixture. The lower and upper baffle plates together form an effective filtration system. The water-powder mixture is first collected by the lower baffle plate and then further adsorbed onto the upper baffle plate through rotation. This dual barrier not only improves collection efficiency but also effectively filters the water-powder mixture through the oblique flow channels on the baffle plate, separating the water and powder in the mixture for subsequent processing.

[0039] As attached Figure 1 To the attached Figure 11 As shown:

[0040] The present invention provides a precision surface grinding device for copper and aluminum plate production, comprising a mounting frame 11, a secondary frame 12 is mounted above the mounting frame 11, a top cover plate 14 is mounted on the upper side of the secondary frame 12, a conveying device 13 is mounted between the top cover plate 14 and the secondary frame 12, the top cover plate 14 comprises a top cover shell 21, a dust collecting device 22, a driving device 23 and a dust collecting box 45 are mounted inside the top cover shell 21, the driving device 23 is arranged in the middle of the top cover shell 21, and the two sides of the driving device 23 are respectively opposite to each other. It is said to be equipped with a dust collecting device 22 and a dust collecting box 45. The driving device 23 includes a middle gear 37. A polishing device 57 is symmetrically provided on the outside of the middle gear 37. A rotating motor 58 is installed on the top of the middle gear 37. The polishing device 57 includes a driving gear shaft 34 meshing with the middle gear 37 and a polishing assembly 48. A connecting column 35 is connected below the driving gear shaft 34. The lower end of the connecting column 35 is connected to an adsorption disk 36. A dust cover 38 is installed at the bottom of the adsorption disk 36. A polishing plate 42 is connected below the dust cover 38. The outer array of the polishing plate 42 is provided with a plurality of dust collecting scrapers 39, the driving gear shaft 34 is rotatably connected to the inner wall of the top cover shell 21 with a fixing rod, the driving gear shaft 34 is eccentrically provided with a second connecting shaft 33, the end of the second connecting shaft 33 is hinged with a first connecting shaft 32, the first connecting shaft 32 is connected to the dust collecting device 22, the dust collecting device 22 includes a box body 28, a fixed partition 52 and a piston plate 31 fixedly connected to the first connecting shaft 32, the box body 28 is provided with a cavity, the cavity is provided with a fixed partition 52, the fixed The partition 52 divides the cavity into a water collecting chamber 50 and a dust suction chamber 51. The dust suction chamber 51 is arranged on one side of the piston plate 31. A connecting rod 59 is connected to the inner side of the piston plate 31. The end of the connecting rod 59 passes through the fixed partition 52 and is connected to a piston push plate 60. The piston push plate 60 moves in the water collecting chamber 50. A side air duct 44 is connected to the outside of the box body 28. One end of the side air duct 44 is communicated with the dust suction chamber 51, and the other end of the side air duct 44 is connected to the adsorption plate 36. The lower side of the water collecting chamber 50 has a water nozzle that can spray water to the product.

[0041] In this embodiment, when the middle gear 37 starts to rotate, a large amount of water-powder mixture will be generated on the surface of the copper-aluminum plate when the copper-aluminum plate is polished. In order to collect this water-powder mixture, the dust collecting scraper 39 will rotate. Under the centrifugal force generated by the rotation, the water-powder mixture is further sent to the adsorption disk 36 and the dust shielding cover 38 for collection. At the same time, the piston plate 31 is performing reciprocating motion. A cavity is formed between the adsorption disk 36 and the dust shielding cover 38. When the piston plate 31 moves in a certain direction, it will suck air into the cavity, thereby forming a negative pressure between the cavities. When the piston plate 31 moves in the opposite direction and the cavity, the volume of the cavity becomes smaller. At this time, the accumulated dust is discharged to the outside through the second one-way valve 56. The dust eventually enters the dust collecting cavity 46. During the process of resetting the piston plate 31, the air pressure inside the cavity decreases, generating adsorption force. At this time, the side air duct 44 will guide the dust inside the cavity into the cavity. As the piston plate 31 is squeezed again, the dust in the cavity is discharged again, and the driving gear shaft drives the polishing plate to rotate, thereby realizing efficient grinding of the copper and aluminum plates and improving work efficiency. The first scraper and the second scraper on the dust collecting scraper work together to effectively collect the water-powder mixture generated during the grinding process, avoiding the problem of dust flying and environmental pollution. Moreover, through the centrifugal force generated by rotation, the water-powder mixture is sent into the adsorption chamber for aggregation, which not only improves the dust collection efficiency, but also makes subsequent processing more convenient. The reciprocating motion of the piston plate generates negative pressure and adsorption force in the dust collection chamber, further enhancing the dust collection effect and ensuring the cleanliness of the working environment.

[0051] Specific use of the present invention:

[0052] When using the present invention, first move the present invention to the polishing workshop, and connect the external cooling water pipe to the water inlet pipe 27. After the connection is completed, the power supply of the present invention can be connected. Then, after the connection is completed, the drive motor 16 of the present invention will be started with the rotating motor 58, so that the drive motor 16 and the rotating motor 58 will move.

[0053] When the rotary motor 58 starts rotating, it first drives the central gear 37, which in turn drives the polishing devices 57 on both sides. Simultaneously, the drive motor 16 is also activated, rotating the third rotating shaft 26, which in turn drives the conveyor belt 24. Subsequently, a copper-aluminum plate is placed on the surface of the conveyor belt 24 and driven into the interior of the device, where it comes into contact with the drive device 23. During the movement of the polishing device 57, the drive gear shaft 34 and the central gear 37 cooperate, causing the second connecting shaft 33 to rotate and the first connecting shaft 32 to oscillate. The oscillation of the first connecting shaft 32 propels the piston plate 31 to reciprocate, which in turn pushes the piston push plate 60 to squeeze the water collection chamber 50. After the water collection chamber 50 is squeezed, the cooling water inside is squeezed out and transported through the drain pipe 29 to the interior of the circular nozzle 30. Finally, it is sprayed out through the drain port 43 to cool the copper-aluminum plate, preventing deformation during processing. The movement of the polishing device effectively polishes the copper-aluminum plate, improving its surface quality. This is especially important for the processing of copper and aluminum plates that require high precision and high surface quality. Through the operation of the cooling water system, the copper and aluminum plates can be cooled during the processing process, which not only prevents the deformation of the copper and aluminum plates caused by the increase in temperature, but also extends the service life of equipment and tools.

[0054] When the drive gear shaft 34 begins to rotate, it drives the polishing plate 42 to rotate synchronously. Once the polishing plate 42 contacts the copper-aluminum plate, it begins to polish it. During this polishing process, a large amount of water-gouache mixture will be produced on the surface of the copper-aluminum plate. In order to collect this water-gouache mixture, the ash-collecting scraper 39 plays a key role during rotation. The first scraper 40 and the second scraper 41 on the ash-collecting scraper 39 work together, wherein the first scraper 40 is designed to be shorter than the second scraper 41, so that the water-gouache mixture can enter the space between the two through the opening gap of the first scraper 40. When the water-gouache mixture enters the area between the two, it will first be collected by the lower baffle plate 47 through rotation and then the rotation will act again to adsorb the water-gouache mixture onto the baffle plate 47 set on the upper side. On these two baffle plates 47, the water-gouache mixture will be effectively intercepted and effectively filtered by the design of its oblique flow channel. The design of the ash-collecting scraper 39 cleverly solves the problem of collecting the water-gouache mixture generated during the polishing process. The collaboration between the first and second scraping blades 40, as well as the unique opening of the first scraping blade, allows the water-powder mixture to smoothly enter the space between the dust-collecting scraper and the baffle plate, preventing splashing and scattering of the mixture. The lower and upper baffle plates 47 together form an effective filtration system. The water-powder mixture is first collected by the lower baffle plate 47 and then further adsorbed onto the upper baffle plate 47 through rotation. This dual barrier not only improves collection efficiency but also effectively filters the water-powder mixture through the oblique flow channels on the baffle plates, separating the water and powder in the mixture for easier subsequent processing.

[0055] The drive gear shaft rotates the polishing plate, achieving efficient polishing of the copper and aluminum plates. This process not only improves work efficiency but also ensures uniform polishing quality. Simultaneously, the first and second scrapers on the dust collection scraper work in tandem to effectively collect the water-powder mixture produced during the polishing process. Furthermore, through the centrifugal force generated by the rotation, the water-powder mixture is fed into the adsorption chamber 53 for collection. Meanwhile, the piston plate 31 reciprocates. When the piston plate 31 moves in a certain direction, it evacuates the interior of the dust collection chamber 51, thereby creating a negative pressure state within the dust collection chamber 51 to facilitate absorption of the water-powder mixture.

[0056] The present invention provides a precision surface polishing device for copper and aluminum plate production. The device is equipped with an extrusion water collection chamber. When the rotary motor starts rotating, it first drives the central gear, which in turn drives the polishing devices on both sides to move. Simultaneously, the drive motor is also started, driving the third rotating shaft to rotate, which in turn drives the conveyor belt for transmission. Subsequently, the copper and aluminum plates are placed on the surface of the conveyor belt and driven into the interior of the device to contact the drive device. During the movement of the polishing device, the drive gear shaft and the central gear cooperate to rotate, causing the second connecting shaft to rotate and driving the first connecting shaft to swing. The swinging of the first connecting shaft drives the piston plate to reciprocate, and the reciprocating motion of the piston plate further drives the piston push plate to squeeze the water collection chamber. After the water collection chamber is squeezed, the cooling water inside is squeezed out and transported to the inside of the circular nozzle through a drain pipe. Finally, water is sprayed out through the drain port to cool the copper and aluminum plates, preventing deformation of the copper and aluminum plates during processing. The movement of the polishing device can effectively polish the copper and aluminum plates and improve their surface quality. This is especially important for the processing of copper and aluminum plates that require high precision and high surface quality. Through the operation of the cooling water system, the copper and aluminum plates can be cooled during the processing process, which not only prevents the deformation of the copper and aluminum plates caused by the increase in temperature, but also extends the service life of equipment and tools.

[0057] The present invention provides a precision surface polishing device for copper and aluminum plate production. The device is equipped with an ash-collecting scraper. When the drive gear shaft begins to rotate, it drives the polishing plate to rotate synchronously. Once the polishing plate contacts the copper and aluminum plates, it begins polishing them. During this polishing process, a large amount of gouache mixture is generated on the surface of the copper and aluminum plates. The ash-collecting scraper plays a key role in collecting this gouache mixture during rotation. The first scraper and the second scraper on the ash-collecting scraper work together, with the first scraper being shorter than the second scraper, allowing the gouache mixture to enter the space between the first scraper and the second scraper through the opening of the first scraper. When the gouache mixture enters the area between the first and second scrapers, it is first collected by the lower baffle plate through rotation. Then, the rotation acts again, adsorbing the gouache mixture onto the upper baffle plate. The gouache mixture is effectively intercepted on these two baffle plates, and the gouache is effectively filtered through the design of their oblique flow channels. The design of the ash-collecting scraper cleverly solves the problem of collecting the gouache mixture generated during the polishing process. The collaboration between the first and second scrapers, along with the unique opening of the first scraper, allows the water-powder mixture to flow smoothly into the space between the dust-collecting scraper and the baffle plate, preventing splashing and scattering of the mixture. The lower and upper baffle plates together form an effective filtration system. The water-powder mixture is first collected by the lower baffle plate and then further adsorbed onto the upper baffle plate through rotation. This dual barrier not only improves collection efficiency but also effectively filters the water-powder mixture through the oblique flow channels on the baffle plate, separating the water and powder in the mixture for subsequent processing.

[0058] The present invention provides a precision surface grinding device for the production of copper and aluminum plates. By providing a dust suction chamber and driving the polishing plate to rotate via a gear shaft, efficient grinding of the copper and aluminum plates is achieved. This process not only improves work efficiency but also ensures the uniformity of grinding quality. At the same time, the first scraper and the second scraper on the dust collecting scraper work together to effectively collect the water-powder mixture generated during the grinding process. This design avoids the flying of dust, thereby protecting the cleanliness of the environment. Furthermore, through the centrifugal force generated by the rotation, the water-powder mixture is sent into the adsorption chamber for aggregation, which not only improves the dust collection efficiency but also brings convenience to subsequent processing work. On the other hand, the piston plate is performing reciprocating motion. When the piston plate moves in a certain direction, it will perform a vacuum operation on the inside of the dust suction chamber, thereby forming a negative pressure state in the dust suction chamber to facilitate the absorption of the water-powder mixture.
