Description

Technical Field

[0001] This utility model relates to the field of optical lens processing equipment technology, and in particular to a flat grinding machine. Background Technology

[0002] In the process of processing optical lenses, large pieces of glass are first cut into small pieces using diamond tools according to different uses and needs. After the small pieces are beveled, they enter the grinding and polishing process. Then, a flat grinder is used to grind and polish the glass pieces on both sides.

[0003] Existing surface grinders (such as the glass surface grinder disclosed in application number 201320435739.6) grind and polish glass sheets by placing a glass clamp on a rotating grinding wheel and engaging the teeth on the glass clamp with the teeth on the inner column and outer ring. The glass sheet is then placed into the glass placement slot on the glass clamp, and a cylinder drives the upper grinding disc to move down so that the upper grinding disc comes into contact with the glass sheet. The polishing powder and water supply is turned on to add polishing powder and water to the upper grinding disc, and the motor is turned on to drive the rotating grinding wheel to grind and polish both sides of the glass sheet. However, surface grinders with this structure can only grind and polish a small batch of glass sheets at a time, and the efficiency is low when grinding and polishing large batches of glass sheets.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] This utility model provides a surface grinder, the structure of which is as follows: Figure 1 - Figure 3As shown, the device includes a polishing mechanism 100, a first driving mechanism 200, and a second driving mechanism 300. The polishing mechanism 100 includes a polishing base 110, multiple polishing wheels 120, and multiple carriers 130. The polishing base 110 has a polishing cavity 111 with a top opening. Each polishing wheel 120 is built into the polishing cavity 111 from bottom to top. Each carrier 130 is placed on the top surface of each polishing wheel 120, and a placement slot on the carrier 130 is used to place glass slides. The first driving mechanism 200 is connected to each polishing wheel 120 and is used to drive each polishing wheel 120 to move up and down to adjust the height of each polishing wheel 120. The second driving mechanism 300 is connected to each polishing wheel 120 and is used to drive each polishing wheel 120 to rotate synchronously and to cause relative movement between the carrier 130 and the polishing wheel 120.

[0028] In use, the polishing chamber 111 contains a certain amount of polishing liquid. Each carrier 130 is placed on the top surface of each polishing wheel 120, and each glass slide is placed in the placement slot on the carrier 130. By operating the first drive mechanism 200, the first drive mechanism 200 can drive each polishing wheel 120 to move up and down, thereby adjusting the height of each polishing wheel 120 so that all polishing wheels 120 enter the polishing chamber 111, and the upper polishing wheel 120... The bottom surface of the glass plate abuts against the glass plate on the polishing wheel 120 below it. By operating the second drive mechanism 300, the second drive mechanism 300 can drive each polishing wheel 120 to rotate synchronously and cause the carrier 130 to move relative to the polishing wheel 120. Thus, the glass plate on the carrier 130 can be polished by the polishing wheels 120 above and below. This flat grinder can not only polish both sides of the glass plate, but also increase the number of glass plates polished at one time, making it suitable for use when polishing large batches of glass plates.

[0029] As a preferred embodiment, please refer to Figure 3 and Figure 4The polishing mechanism 100 further includes multiple inner rings 140 and multiple internal toothed rings 150. Each inner ring 140 is coaxially fixed to the top surface of each polishing wheel 120. Each internal toothed ring 150 is coaxially fixed to the polishing cavity 111 from bottom to top. The outer wall of the carrier 130 abuts against the outer wall of the inner ring 140, and the teeth on the outer wall of the carrier 130 mesh with the internal toothed rings 150. Each carrier 130 is placed on the top surface of each polishing wheel 120, and the mechanism is operated... The first driving mechanism 200 can drive each of the polishing wheels 120 to move up and down, thereby adjusting the height of each polishing wheel 120 so that all polishing wheels 120 enter the polishing chamber 111, and the bottom surface of the upper polishing wheel 120 abuts against the glass sheet on the lower polishing wheel 120. At this time, except for the topmost polishing wheel 120, each of the other polishing wheels 120 corresponds one-to-one with the inner toothed ring 150 of each layer. The outer walls of each of the carriers 130 on the wheel 120 abut against the outer walls of the corresponding inner rings 140. The teeth on the outer walls of each carrier 130 on each layer of the polishing wheel 120 mesh with the corresponding inner toothed rings 150. By operating the second drive mechanism 300, the second drive mechanism 300 can drive each polishing wheel 120 to rotate synchronously. During the rotation of the polishing wheel 120, the inner rings 140 fixedly connected to the polishing wheel 120 will rotate accordingly. The carrier 130 on the grinding wheel 120 will rotate. Since the outer wall of the carrier 130 on the grinding wheel 120 abuts against the inner ring 140, and the teeth on the outer wall of the carrier 130 mesh with the inner toothed ring 150, the carrier 130 is limited by the inner ring 140 and the inner toothed ring 150. The carrier 130 will rotate, thereby moving relative to the grinding wheels 120 above and below it. Thus, the glass sheet on the carrier 130 can be ground and polished by the grinding wheels 120 above and below.

[0030] As a preferred embodiment, please refer to Figure 6 A receiving groove 121 is coaxially formed on the bottom surface of the polishing wheel 120. The receiving groove 121 is used for the inner ring 140 on the lower polishing wheel 120 to slide into, thereby facilitating the upper polishing wheel 120 to approach the lower polishing wheel 120, so that the upper polishing wheel 120 can abut against the glass sheet on the lower polishing wheel 120.

[0031] As a preferred embodiment, please refer to Figure 3 and Figure 5The first driving mechanism 200 includes a mounting assembly 210, multiple connecting assemblies 220, a hook 234 assembly 230, and a telescopic driving member 240. The mounting assembly 210 is disposed above the topmost polishing wheel 120 and is fixedly connected to the top surface of the topmost polishing wheel 120. Each connecting assembly 220 is disposed between adjacent polishing wheels 120 and connects adjacent polishing wheels 120. The connecting assembly 220 is deformable. The hook 234 assembly 230 is disposed above the mounting assembly 210 and is used to hook or release the mounting assembly 210. The output end of the telescopic driving member 240 is connected to the hook 234 assembly 230 for driving. The gripper hook 234 assembly 230 moves up and down to adjust its height. Initially, all polishing wheels 120 are located within the polishing chamber 111, and adjacent polishing wheels 120 abut against each other. When it is necessary to place the carrier 130 and glass slides onto the polishing wheels 120, the telescopic drive 240 is operated. The telescopic drive 240 drives the gripper hook 234 assembly 230 downwards, thereby adjusting its height so that it reaches the mounting assembly 210. Then, the gripper hook 234 assembly 230 hooks onto the mounting assembly 210. Further adjustments are made by operating the telescopic drive 240... The telescopic drive component 240 can drive the gripper hook 234 assembly 230 to move upward, thereby driving the mounting assembly 210 and the topmost polishing wheel 120 to move upward until the topmost polishing wheel 120 and the polishing wheel 120 below it reach a preset distance. Then the lower polishing wheel 120 begins to move upward until the polishing wheel 120 of this layer reaches a preset distance with the polishing wheel 120 below it. This process continues until the top surface of the bottommost polishing wheel 120 is removed from the polishing cavity 111. Then the carrier 130 and the glass plate are placed on the bottommost layer. On the polishing wheel 120, by manipulating the telescopic drive 240, the grab hook 234 assembly 230 can be driven to move downwards until the bottom polishing wheel 120 enters the polishing chamber 111 and reaches a preset position. The teeth on the outer wall of the carrier 130 on the bottom polishing chamber 111 engage with the bottom inner toothed ring 150. Then, the carrier 130 and a glass plate are placed on the next upper polishing wheel 120. By manipulating the telescopic drive 240, the grab hook 234 assembly 230 can be driven to move downwards until the next upper polishing wheel 120 enters the polishing chamber 111 and reaches a preset position.The teeth on the outer wall of the carrier 130 on the uppermost grinding and polishing chamber 111 engage with the inner toothed ring 150 of the uppermost layer, repeating this process to place the carrier 130 and glass slides onto the grinding and polishing wheels 120 of each layer.

[0032] As a preferred embodiment, please refer to Figure 5 The mounting assembly 210 includes a mounting plate 211, a plurality of vertical rods 212, and two horizontal rods 213. The top of each vertical rod 212 is fixedly connected to the mounting plate 211, and the bottom of each vertical rod 212 is fixedly connected to the top surface of the top-level polishing wheel 120. The two horizontal rods 213 are arranged opposite to each other on both sides of the mounting plate 211, and there is a first gap between each horizontal rod 213 and the mounting plate 211. Both ends of each horizontal rod 213 are fixed to the mounting plate 211. The hook 234 assembly 230 is used to hook or release the two horizontal bars 213. When the topmost polishing wheel 120 enters the polishing chamber 111, the mounting assembly 210 is located outside the polishing chamber 111, which facilitates the hook 234 assembly 230 to hook or release the mounting assembly 210. When the hook 234 assembly 230 hooks or releases the two horizontal bars 213, it achieves connection and separation with the topmost polishing wheel 120, so that the rotation of each layer of polishing wheels 120 is not disturbed.

[0033] As a preferred embodiment, please refer to Figure 3 The connecting assembly 220 includes multiple connecting ropes 221. One end of each connecting rope 221 is fixedly connected to the bottom surface of the upper polishing wheel 120, and the other end of each connecting rope 221 is fixedly connected to the top surface of the lower polishing wheel 120. This allows adjacent polishing wheels 120 to abut against each other and separate, facilitating the placement of the carrier 130 and the glass sheet on the polishing wheel 120, and facilitating the polishing of both sides of the glass sheet through adjacent polishing wheels 120.

[0034] As a preferred embodiment, please refer to Figure 3 The connection points of each of the connecting ropes 221 to the upper polishing wheel 120 are all located within the receiving groove 121, and the connection points of each of the connecting ropes 221 to the lower polishing wheel 120 are all located within the inner ring 140. When adjacent polishing wheels 120 are close to each other, the connecting ropes 221 can be located within the inner ring 140 to prevent the connecting ropes 221 from entering the carrier 130 and interfering with the polishing of the glass sheet.

[0035] As a preferred embodiment, please refer to Figure 5The gripper hook 234 assembly 230 includes a support plate 231, a guide rod 232, two drive shafts 233, two grippers 234, and two rotation drive components 235. The guide rod 232 is vertically arranged, and its lower end is fixedly connected to the support plate 231. The two drive shafts 233 are arranged horizontally on both sides of the support plate 231, and there is a second distance between each drive shaft 233 and the support plate 231. Both ends of the two drive shafts 233 are rotatably connected to the support plate 231. The upper ends of the two grippers 234 are fixedly connected to the two drive shafts 233 one-to-one. The fixed ends of the two rotation drive components 235 are fixedly connected to the support plate 231. The output end of the drive component 235 is coaxially and fixedly connected to one end of each of the two drive shafts 233, and is used to drive the two drive shafts 233 to rotate synchronously in opposite directions so that the lower ends of the two hooks 234 hook or release the two horizontal bars 213. The output end of the telescopic drive component 240 is fixedly connected to the support plate 231, and is used to drive the support plate 231 to move up and down to adjust the height of the two hooks 234. By operating the two rotation drive components 235, the two rotation drive components 235 can drive the two drive shafts 233 to rotate synchronously in opposite directions, so that the lower ends of the two hooks 234 hook or release the two horizontal bars 213. The hook 234 assembly has a simple structure and is safe and effective.

[0036] As a preferred embodiment, please refer to Figure 3 The second drive mechanism 300 includes a rotating shaft 310 and a drive assembly 320. The rotating shaft 310 is vertically arranged and coaxial with each of the polishing wheels 120. The rotating shaft 310 has a splined section 311 and a smooth rod section 312 from top to bottom. The polishing wheels 120 have a first perforated hole 122 coaxially formed on them. Each polishing wheel 120 is sleeved on the splined section 311 through the first perforated hole 122. The drive assembly 320 is connected to the smooth rod section 312 and is used to drive the rotating shaft 310. Rotation: By manipulating the drive assembly 320, the drive assembly 320 can drive the rotating shaft 310 to rotate. Since each of the polishing wheels 120 is sleeved on the spline segment 311 through the corresponding first flower hole 122, when the rotating shaft 310 rotates, it can drive each of the polishing wheels 120 to rotate synchronously. Furthermore, the rotating shaft 310 can guide each of the polishing wheels 120, allowing each of the polishing wheels 120 to move up and down along the length direction of the rotating shaft 310.

[0037] In a preferred embodiment, the drive assembly 320 can be directly connected to the guide rod section 312 using a suitable type of motor, or it can be indirectly connected to the guide rod section 312 using a belt drive assembly.

[0038] As a preferred embodiment, please refer to Figure 3 and Figure 4 The mounting plate 211 has a second perforated hole 2111 coaxially formed on it, and is spring-loaded onto the spline segment 311 through the second perforated hole 2111. This allows the mounting plate 211 to rotate synchronously when the rotating shaft 310 rotates, and the rotating shaft 310 can guide the mounting plate 211 so that the mounting plate 211 can move up and down along the length of the rotating shaft 310.

[0039] As a preferred embodiment, please refer to Figure 1 and Figure 2 The aforementioned flat grinder also includes a frame 400, a polishing base 110 disposed on the frame 400, a guide rod 232 slidably connected to the frame 400, and a fixed end of the telescopic drive component 240 fixedly connected to the frame 400. The frame 400 can provide support for the polishing base 110, the guide rod 232, and the telescopic drive component 240.

[0040] In a preferred embodiment, the polishing base 110 has a drain port that communicates with the polishing chamber 111 to facilitate the discharge of polishing liquid from the polishing chamber 111. The drain port is not shown in the figure.

[0041] In a preferred embodiment, the surface grinder further includes a polishing fluid addition mechanism. Each of the polishing wheels 120 has an overflow hole. The polishing fluid addition mechanism is used to add polishing fluid into the overflow hole on the top polishing wheel 120. The polishing fluid flows into each layer of polishing wheels 120 along each overflow hole. The overflow hole and the polishing fluid addition mechanism are not shown in the figure.

[0042] In a preferred embodiment, the polishing fluid adding mechanism includes a polishing fluid conduit and a polishing fluid provider. One end of the polishing fluid conduit is placed on the topmost polishing wheel 120. The polishing fluid provider is used to store polishing fluid. The outlet end of the polishing fluid provider is connected to the other end of the polishing fluid conduit and is used to provide polishing fluid into the polishing fluid conduit, thereby providing polishing fluid to each layer of the polishing wheels 120.

[0043] To better understand this utility model, the following is combined with... Figure 1 - Figure 6 The working principle of the technical solution of this utility model will be described in detail below:

[0044] In the initial position, each of the polishing wheels 120 is located within the polishing chamber 111, and adjacent polishing wheels 120 abut against each other. When it is necessary to place the carrier 130 and glass slides onto each of the polishing wheels 120, by manipulating the telescopic drive member 240, the telescopic drive member 240 can drive the hook 234 assembly 230 to move downward, thereby adjusting the height of the hook 234 assembly 230 so that the hook 234 assembly 230 reaches the mounting assembly 210. Then, by manipulating the two rotation drive members 235, the two rotation drive members 235 can drive the two drive shafts 233 to rotate synchronously in opposite directions, so that the lower ends of the two hooks 234 hook the two corresponding objects. The horizontal bar 213, through the operation of the telescopic drive component 240, can drive the hook 234 assembly 230 to move upward, thereby driving the mounting plate 211 and the topmost polishing wheel 120 to move upward until the topmost polishing wheel 120 and the polishing wheel 120 below it reach a preset distance. At this time, the connecting ropes 221 between the topmost polishing wheel 120 and the polishing wheel 120 below it are taut. Then, the lower polishing wheel 120 begins to move upward until the polishing wheel 120 of this layer and the polishing wheel 120 below it reach a preset distance. At this time, the polishing wheel 120 of this layer and the polishing wheel 120 below it reach a preset distance. The connecting ropes 221 between the polishing wheels 120 are taut, and then the lower polishing wheel 120 begins to move upward, and so on, until the top surface of the bottom polishing wheel 120 is removed from the polishing cavity 111. Then the carrier 130 and the glass plate are placed on the bottom polishing wheel 120. By operating the telescopic drive 240, the telescopic drive 240 can drive the hook 234 assembly 230 to move downward until the bottom polishing wheel 120 enters the polishing cavity 111 and reaches a preset position. The teeth on the outer wall of the carrier 130 on the bottom polishing cavity 111 engage with the bottom inner toothed ring 150, and then move to the next upper polishing wheel. The carrier 130 and glass sheet are placed on the 120. By operating the telescopic drive 240, the telescopic drive 240 can drive the hook 234 assembly 230 to move downward until the next uppermost polishing wheel 120 enters the polishing chamber 111 and reaches a preset position. The bottom surface of the next uppermost polishing chamber 111 abuts against the glass sheet on the bottommost polishing wheel 120. The teeth on the outer wall of the carrier 130 on the next uppermost polishing chamber 111 engage with the next uppermost internal toothed ring 150. This process is repeated to place the carrier 130 and glass sheet on each layer of polishing wheels 120, so that the bottom surface of the upper polishing wheel 120 abuts against the glass sheet on the lower polishing wheel 120.By manipulating the drive assembly 320, the drive assembly 320 can drive the rotating shaft 310 to rotate. Since each of the polishing wheels 120 is sleeved on the spline segment 311 via the corresponding first flower hole 122, the rotation of the rotating shaft 310 can drive each of the polishing wheels 120 to rotate synchronously. During the rotation of the polishing wheel 120, the inner ring 140 fixedly connected to the polishing wheel 120 will rotate accordingly, and at the same time, the carrier 130 on the polishing wheel 120 will rotate accordingly. Since the outer side of the carrier 130 on the polishing wheel 120... The wall of the carrier 130 abuts against the inner ring 140, and the teeth on the outer wall of the carrier 130 mesh with the inner toothed ring 150. The carrier 130 is limited by the inner ring 140 and the inner toothed ring 150, causing it to rotate and move relative to the polishing wheels 120 above and below it. This allows the polishing wheels 120 to polish the glass sheets on the carrier 130. This flat grinder can polish both sides of the glass sheet and increases the number of glass sheets polished in a single pass, making it suitable for large-scale polishing of glass sheets.

[0045] The surface mill provided by this utility model has the following beneficial effects:

[0046] (1) Since each of the polishing wheels 120 is sleeved on the spline section 311 through the corresponding first flower hole 122, when the rotating shaft 310 rotates, it can drive each of the polishing wheels 120 to rotate synchronously, and the rotating shaft 310 can guide each of the polishing wheels 120 so that each of the polishing wheels 120 can move up and down along the length direction of the rotating shaft 310;

[0047] (2) During the rotation of the polishing wheel 120, the inner ring 140 fixedly connected to the polishing wheel 120 will rotate along with it, and the carrier 130 on the polishing wheel 120 will also rotate along with it. Since the outer wall of the carrier 130 on the polishing wheel 120 abuts against the inner ring 140, and the teeth on the outer wall of the carrier 130 mesh with the inner toothed ring 150, the carrier 130 is limited by the inner ring 140 and the inner toothed ring 150, and the carrier 130 will rotate, thereby moving relative to the polishing wheels 120 above and below it. Thus, the glass sheet on the carrier 130 can be polished by the polishing wheels 120 above and below it.

[0048] (3) This flat grinder can not only grind and polish both sides of the glass sheet, but also increases the number of glass sheets that can be ground and polished in a single batch, making it suitable for use when grinding and polishing glass sheets in large batches.

[0049] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
