[0030] The rubber product is moved to the grinding mechanism 3 by the transport mechanism 2. Then, the grinding mechanism 3 grinds and removes the aging layer, oxide scale or residual deposits on the top surface and edges of the rubber product. After the grinding process is completed, the transport mechanism 2 continues to move the ground rubber product forward until it is transported to the placement table 4 for temporary storage. Finally, the unloading mechanism 5 clamps and unloads the rubber product temporarily stored on the placement table 4. In this embodiment, the coordinated operation of the transport mechanism 2, the grinding mechanism 3 and the unloading mechanism 5 replaces the traditional manual operation of loading, positioning, grinding and unloading, which greatly reduces labor intensity and improves grinding efficiency. The grinding process is controlled by a mechanical structure, which effectively improves the grinding accuracy. Moreover, the placement table 4 and the transport mechanism 2 can effectively make the grinding, temporary storage and unloading processes of this embodiment smooth and reduce the waiting time between processes.

The first moving plate 205 is provided with a first clamping part 206 and a second clamping part 207 for clamping rubber products. The first clamping part 206 and the second clamping part 207 drive the rubber products to move on the workbench 201 through the first moving plate 205.

[0032] The first movable plate 205 is provided with a lifting cylinder 208 on its front side. The free end of the lifting cylinder 208 drives the L-shaped lifting platform 209 connected to it. The lifting cylinder 208 drives the L-shaped lifting platform 209 to rise and fall simultaneously on the top and front side of the first movable plate 205. The first clamping part 206 and the second clamping part 207 are located on the left and right sides of the top of the L-shaped lifting platform 209, respectively. The L-shaped lifting platform 209 drives the first clamping part 206 and the second clamping part 207, together with the rubber product, to rise and fall on the worktable 201.

[0033] The first clamping part 206 includes a first clamping cylinder 210 and a second clamping cylinder 211 arranged back to back, and the free ends of the first clamping cylinder 210 and the second clamping cylinder 211 are respectively driven to be connected to a first clamping block 212 and a second clamping block 213, and a first pad 214 and a second pad 215 are respectively provided on the side of the first clamping block 212 and the second clamping block 213 near the rubber product;

[0034] The second clamping part 207 includes a third clamping cylinder 216 and a fourth clamping cylinder 217 arranged back to back, and the free ends of the third clamping cylinder 216 and the fourth clamping cylinder 217 are respectively driven to connect a third clamping block 218 and a fourth clamping block 219, and a third pad 220 and a fourth pad 221 are respectively provided on the side of the third clamping block 218 and the fourth clamping block 219 near the rubber product;

[0035] A first sensing unit is provided between the first movable plate 205 and the worktable 201. The first sensing unit includes a first sensing plate 222 installed on the front side of the first movable plate 205, a first slotted sensor 223 installed from right to left on the front side of the worktable 201 for positioning the starting point of the first movable plate 205, a second slotted sensor 224 for positioning the position of the first clamping part 206, a third slotted sensor 225 for positioning the grinding position, and a fourth slotted sensor 226 for positioning the ending point of the first movable plate 205. The first movable plate 205 drives the first sensing plate 222 to sense and cooperate with the first slotted sensor 223, the second slotted sensor 224, the third slotted sensor 225 and the fourth slotted sensor 226 respectively.

[0036] Two rubber products to be polished are placed on the top of the workbench 201, and then the two rubber products are respectively located in the first clamping part 206 and the second clamping part 207. Then, the first clamping cylinder 210 and the second clamping cylinder 211 drive the first clamping block 212 together with the first pad 214 and the second clamping block 213 together with the second pad 215 to move closer to each other, so that the rubber product located in the first clamping part 206 can be clamped and fixed. The third clamping cylinder 216 and the fourth clamping cylinder 217 drive the third clamping block 218 together with the third pad 220 and the fourth clamping block 219 together with the fourth pad 221 to move closer to each other, so that the rubber product located in the second clamping part 207 can be clamped. At this time, the first moving plate 205 is at the starting point of movement, and the first sensing plate 222 is in sensing engagement with the first slot-shaped sensor 223.

[0037] After both rubber products are clamped, the first moving plate 205, together with the first clamping part 206, the second clamping part 207, and the two rubber products, can be driven by the first driving cylinder 204 to move synchronously to the left side of the worktable 201 until the first sensing plate 222 leaves the first slot-shaped sensor 223 and senses and engages with the second slot-shaped sensor 224. At this time, the rubber product in the first clamping part 206 is located at the grinding mechanism 3, and the second clamping part 207 will be in the original position of the first clamping part 206. Finally, the grinding mechanism 3 can be used to grind the rubber product inside the first clamping part 206.

[0038] After the grinding work in the first clamping part 206 is completed, the first driving cylinder 204 continues to drive the first moving plate 205, along with the first clamping part 206, the second clamping part 207, and the two rubber products, to move synchronously to the left side of the worktable 201 until the first sensing plate 222 leaves the second slotted sensor 224 and engages with the third slotted sensor 225. At this time, the rubber products in the first clamping part 206 are located at the top of the placement table 4, and the first clamping part 206 is in the open state. The rubber product inside the second clamping part 207 is located at the grinding mechanism 3. The grinding mechanism 3 can then grind the rubber product inside the second clamping part 207. In addition, during the grinding process of the rubber product inside the second clamping part 207, the first clamping part 206 releases the ground rubber product inside it, and at the same time, the unloading mechanism 5 moves and inserts between the first clamping part 206 and the rubber product inside it, and clamps and removes the left and right sides of the rubber product on the placement table 4, thereby completing the unloading action.

[0039] After the grinding work in the second clamping part 207 is completed, the first driving cylinder 204 continues to drive the first moving plate 205, together with the first clamping part 206, the second clamping part 207, and the rubber product in the second clamping part 207, to move synchronously to the left side of the worktable 201 until the first sensing plate 222 leaves the third slot-shaped sensor 225 and senses and engages with the fourth slot-shaped sensor 226. At this time, the first moving plate 205 is at the end point of the movement, and the rubber product in the second clamping part 207 is located at the top of the placement table 4. The second clamping part 207 is in the open state, and the second clamping part 207 will release the ground rubber product inside. At the same time, the unloading mechanism 5 moves and inserts between the second clamping part 207 and the rubber product inside, and clamps and removes the left and right sides of the rubber product on the placement table 4, thereby completing the second unloading action.

[0040] After both rubber products have been ground and cut, the first moving plate 205, together with the first clamping part 206 and the second clamping part 207, can be reset by the first driving cylinder 204 to continue the next round of work. In addition, the L-shaped lifting platform 209, together with the first clamping part 206 and the second clamping part 207, can be raised or lowered at the top of the worktable 201 by the lifting cylinder 208. The height can be adjusted according to the height of the workpiece being clamped so that the first clamping part 206 and the second clamping part 207 can clamp the middle position of the workpiece as much as possible.

[0043] The grinding motor 307 drives the grinding wheel 308 through the synchronous wheel assembly 309 and causes the grinding wheel 308 to rotate within the grinding mounting frame 306, so that the rotating grinding wheel 308 can perform grinding action on the rubber product when it comes into contact with it. The drive motor 304 drives the first lifting frame 302 through the lead screw assembly 305, so that the first lifting frame 302, together with the grinding motor 307 and the grinding wheel 308, moves up or down on the gantry frame 301, thereby adjusting the distance between the grinding wheel 308 and the rubber product and achieving grinding of the rubber product to different depths.

The connecting block 504 drives the second sensing plate 513 to sense and cooperate with the fifth slot-shaped sensor 514 and the sixth slot-shaped sensor 515 respectively.

[0047] The fifth clamping cylinder 507 drives the fifth clamping block 509 together with the fifth pad block 511 and the sixth clamping cylinder 508 drives the sixth clamping block 510 together with the sixth pad block 512 to be located on the left and right sides of the rubber product on the placement platform 4 respectively. Then they move closer to each other to clamp and fix the rubber product located on the top of the placement platform 4. At this time, the second moving plate 503 is at the starting point of movement, and the second sensing plate 513 is in sensing cooperation with the fifth slot-shaped sensor 514.

[0048] Finally, the second driving cylinder 502 drives the second moving plate 503, together with the third clamping part and the rubber product clamped in the third clamping part, to move towards the back of the mounting base 501 until the second sensing plate 513 leaves the fifth slot-shaped sensor 514 and senses and engages with the sixth slot-shaped sensor 515. At this time, the second moving plate 503 is at the end point of the movement, thus completing the unloading action of the polished rubber product on the placement table 4. In addition, the linear drive module 505 drives the second lifting frame 506 together with the third clamping part to rise or fall on the mounting base 501. It can be adjusted according to the height of the workpiece clamped on the placement table 4 so that the third clamping part can clamp the middle position of the workpiece clamped on the placement table 4 as much as possible.
