[0001] The present invention relates to the technical field of grinding devices, and in particular to an integrated device for positioning, conveying and grinding metal plates. Background Art

[0002] Sheet metal processing is a crucial step in modern manufacturing, particularly in applications requiring high precision and surface finish, such as automotive, furniture, and electronic device casings. Traditional sheet metal polishing methods often rely on manual labor, which is not only inefficient but also difficult to ensure consistent polishing quality. With the rapid development of automation technology, automated devices that integrate the positioning, conveying, and polishing of metal sheets have emerged. These devices significantly improve polishing efficiency and quality through mechanization and automation.

[0003] However, existing automated systems that integrate metal sheet positioning, conveying, and grinding still have some shortcomings. In particular, when processing sheets of varying thicknesses, tedious manual adjustments are often required to ensure proper contact between the grinding device and the sheet surface. This not only increases operational difficulty but also reduces production efficiency and flexibility. Furthermore, some systems lack sufficient stability and precision during the grinding process, resulting in suboptimal results and even potential damage to the sheet. Summary of the Invention

DETAILED DESCRIPTION

[0028] The present invention is described below with specific examples, but is not intended to be limiting of the invention.

[0029] Example 1

[0030] like Figure 1-Figure 7 As shown, in this embodiment, a device integrating positioning, conveying and grinding of metal plates is provided, which includes a workbench 1 and a support frame 2. A conveying device, a positioning device and a grinding device are installed on the workbench 1.

[0031] The conveyor is mounted on a workbench 1. Above the conveyor is a conveyor channel for panels. Panels are placed above the conveyor and then, driven by the conveyor's force, travel smoothly through the channel. During this dynamic movement, the panels' surfaces are polished to ensure they meet the required quality standards. The conveyor also includes a conveyor belt 3, an inner support plate 13, and drive rollers 14 that drive the conveyor belt 3. The inner support plate 13 is connected between the two drive rollers 14 to provide support for the conveyor belt 3.

[0032] The positioning device includes multiple positioning rollers 4 aligned in a straight line. These rollers 4 are able to move synchronously up and down above a conveyor channel. The conveyor channel is defined between the positioning rollers 4 and the conveyor device, forming a stable travel path with an infeed and a discharge. Panels are arranged within this channel. When the conveyor device is activated as a driving source, the panels begin to move smoothly along the conveyor channel, guided by the positioning rollers 4. During this process, the conveyor device not only provides the necessary power for the panel movement but also ensures the stability of the entire conveying process.

[0033] The grinding device includes a grinding belt 12 and multiple groups of grinding rollers for supporting the grinding belt 12. The grinding belt 12 is made of a soft material and has a surface of grinding particles. When passing over the surface of the product, the surface of the product will be polished. The multiple groups of grinding rollers include a first grinding roller group, a second grinding roller group, and a third grinding roller group that are horizontally arranged. The three groups of grinding rollers are all arranged horizontally, but each is at a different height level. Specifically, the first roller group is located at the bottom, close to the grinding channel. Immediately above the first roller group, the second roller group is located, with a height increase and a relatively narrow width. Finally, the third roller group is located at the highest point, with a height higher than the second roller group and a width consistent with that of the first roller group. The first grinding roller group includes two first guide rollers 16 arranged at the feed end and the discharge end of the conveying channel. The grinding belt 12 passes around the first guide rollers 16 and forms a grinding position at the lower end of the first guide roller 16. In the grinding channel, two key grinding positions are set, located at the feed end and the discharge end of the channel respectively. These two grinding positions each grind the surface of the plate. The grinding position at the feed end serves as the initial processing point for the plate entering the channel and can perform preliminary or preparatory grinding on its surface. The grinding position at the discharge end is responsible for grinding the plate that has passed through the entire channel to ensure that its surface achieves the required smoothness and finish.

[0034] Among them, the positioning roller 4 is connected to the grinding device through a linkage device. When the height of the positioning roller 4 increases, the height of the grinding position will increase along with the increase of the positioning roller 4. The positioning roller 4 can adjust the height according to the thickness of the plate. The higher the thickness of the plate, the higher the height of the positioning roller 4, and the grinding position on the grinding device will increase along with the increase of the positioning roller 4, but the height of the grinding position will not exceed the height of the positioning roller 4, ensuring that the grinding position can contact the surface of the plate.

[0035] Example 2

[0036] like Figure 1-Figure 7 As shown, based on the first embodiment, this embodiment provides a grinding device, which is specifically as follows:

[0037] The third grinding roller assembly includes two third guide rollers 11, each positioned above the two first guide rollers 16. The second grinding roller assembly includes two second guide rollers 15 positioned inward of the first guide rollers 16. The grinding belt 12 passes over multiple first guide rollers 16, second guide rollers 15, and third guide rollers 11, forming a moving track with a notch at the bottom. This moving track allows a single grinding belt 12 to flexibly create two independent grinding positions. A single drive mechanism can easily drive any guide roller to rotate. In this process, the multiple guide rollers not only provide precise guidance but also ensure stable support for the grinding belt 12 during operation.

[0038] There are three positioning rollers 4, two of which are located outside the two first guide rollers 16. When a panel enters the conveyor channel, it first contacts one of the positioning rollers 4. Fixing ears 5 are fixed to the workbench 1. Guide posts 17 are fixed to the ends of the positioning rollers 4 and rotatably mounted on the connecting plate 6. The connecting plate 6 is slidably mounted on the fixing ears 5 via first elastic members 19. The first elastic members 19 apply downward pressure to the connecting plate 6, ensuring its vertical movement. Two of the three positioning rollers 4 are specifically positioned outside the two first guide rollers 16 to provide initial guidance and positioning for the panel. When a panel is about to enter the conveyor channel, it first contacts one of the three positioning rollers 4, providing precise guidance. Fixing ears 5 are securely mounted on the workbench 1 as a support structure. A connecting plate 6 is attached to each end of the three positioning rollers 4. These connecting plates 6 not only synchronously drive the positioning rollers 4 up and down but also allow the positioning rollers 4 to rotate freely on the connecting plates 6 to accommodate the transport needs of different panels. At the same time, the connecting plate 6 is designed to be slidably mounted on the fixed ear 5. This design enables the entire positioning roller 4 system to be fine-tuned according to the size and shape of the plate, ensuring that the plate always maintains a stable and correct position in the conveying channel.

[0039] Both ends of the second grinding roller group are connected to support plates 9. The second grinding roller group includes two second guide rollers 15. The two ends of the two second guide rollers 15 are rotatably mounted on the two support plates 9 respectively. The support plates 9 are connected to the guide columns 17 through the drive rod 8. The drive rod 8 is slidably mounted on the support frame 2. In the structure of the second grinding roller group, both ends are connected to support plates 9 to provide a stable foundation. This group of rollers consists of two second guide rollers 15. The two ends of these two guide rollers are respectively mounted on the corresponding support plates 9 and allowed to rotate freely, thereby realizing the grinding function. These support plates 9 are tightly connected to the connecting plate 6 through the drive rod 8. This connection method not only ensures the stability of the second grinding roller group, but also enables it to be flexibly adjusted in movement through the connecting plate 6 and the drive mechanism when necessary to adapt to different grinding needs.

[0040] Example 3

[0041] like Figure 1-Figure 7 As shown, based on the first and second embodiments, this embodiment provides a method for installing the first guide roller 16, which is as follows:

[0042] Upper positioning blocks 10 are rotatably mounted on both ends of the third guide roller 11 . The upper positioning blocks 10 are fixed on the support frame 2 . The third guide roller 11 can only rotate on the support frame 2 and cannot move up and down.

[0043] The support frame 2 is provided with a lower positioning block 7 fixed to the end of the first guide roller 16. A slider 18 is slidably mounted inside the lower positioning block 7 via a second elastic body 20. A center shaft 21 is fixed to the end of the first guide roller 16. The center shaft 21 is inserted into the interior of the slider 18. The lower positioning block 7 is firmly mounted on the end of each first guide roller 16 at a specific position of the support frame 2. The intervention of the second elastic body 20 enables the slider 18 to move smoothly therein. At the same time, the end of the first guide roller 16 is equipped with a center shaft 21, which is accurately inserted into the interior of the slider 18, achieving a stable connection between the guide roller and the slider 18. This structural design not only ensures the stable operation of the guide roller, but also through the buffering effect of the elastic body.

[0044] Support frame 2 is equipped with a feed inlet and a discharge inlet, located at the feed and discharge ends of the conveyor channel, respectively. The design of support frame 2 clearly demarcates the positions of the feed inlet and discharge inlet, respectively, at the feed and discharge ends of the conveyor channel. This layout ensures that panels can smoothly enter the conveyor channel for processing and smoothly exit the discharge inlet after polishing, ensuring the continuity of the entire processing process.

[0045] A motor for driving the third guide roller 11 to rotate is fixed inside any upper positioning block 10 , and the motor can drive the corresponding third guide roller 11 to rotate.

[0046] Working principle:

[0047] The panels are placed on top of the conveyor and are driven by the conveyor to move smoothly through the conveyor channel. The conveyor not only provides the power for the movement of the panels, but also ensures a smooth conveying process through its stability and precision.

[0048] The positioning device includes multiple positioning rollers 4 that move synchronously up and down along a straight line, defining a stable conveying path together with the conveyor. The positioning rollers 4 are connected to the support frame 2 via a combination of elastic members and sliders 18. They automatically adjust their height based on the thickness of the panel, ensuring that the panel remains in the correct position during conveyance.

[0049] The grinding device consists of a grinding belt 12 and multiple grinding roller groups. The grinding belt 12 passes over multiple guide rollers and forms a grinding station below the first guide roller 16. As the plate passes through the grinding station, the grinding belt 12 polishes the plate surface. The multiple grinding roller groups are located at different height levels and connected to the positioning roller 4 via a linkage mechanism, which automatically adjusts the height of the grinding station according to changes in plate thickness.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
