Detailed Implementation

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Example 1

[0046] Please see Figures 1-6 The present invention provides the following technical solution: a polishing machine production line, comprising: a polishing machine assembly 1 and a loading / unloading machine assembly 2, wherein the loading / unloading machine assembly 2 cooperates with the polishing machine assembly 1 to realize automated workpiece production, the polishing machine assembly 1 is used to perform surface polishing treatment on the workpiece, wherein the loading / unloading machine assembly 2 comprises: a machine body 20, a feeding unit 21, a loading unit 22 and an unloading unit 23.

[0047] Furthermore, by Figures 1-3 , Figure 5 and Figure 6 As shown, in this embodiment, the machine body 20 is located beside the polishing machine assembly 1. The feeding unit 21 is disposed on the machine body 20 and is used to store the workpiece to be processed and transfer it to the preset loading position. The loading unit 22 is disposed at the top of the polishing machine assembly 1 and is used to transfer the workpiece to be processed output by the feeding unit 21 to the processing position of the polishing machine assembly 1. The unloading unit 23 is disposed on the machine body 20 and is used to receive, position and store the workpiece processed by the polishing machine assembly 1. The unloading unit 23 includes components fixed on the machine body 20. The positioning table 232 and the positioning clamping mechanism 239 disposed on the positioning table 232 for clamping the workpiece. The positioning clamping mechanism 239 includes two sets of clamping rods 2391 distributed in a "cross" and a driving mechanism 2392 that drives the two clamping rods 2391 in the same set to move in opposite directions or in the opposite direction. After adopting the above scheme, when in use, firstly, the feeding unit 21 starts to operate, and smoothly transports the stored workpieces to be processed to the preset feeding position according to the preset transmission rhythm, waiting for the feeding unit 22 to grab them.

[0048] When the workpiece to be processed reaches the preset loading position, the loading unit 22 starts, moves precisely to the position and grabs the workpiece to be processed. Then, the loading unit 22 accurately transfers the workpiece to be processed to the processing position of the polishing machine assembly 1 according to the set path, and completes the loading operation.

[0049] Once the polishing machine assembly 1 detects a workpiece at the processing station, it immediately starts the surface polishing process to automate the processing of the workpiece.

[0050] After the workpiece is processed, the unloading unit 23 starts working. At this time, the loading unit 22 transports the processed workpiece to the position that the unloading unit 23 can receive. The relevant mechanism of the unloading unit 23 will accurately receive the workpiece and transfer it to the positioning table 232.

[0051] Next, the positioning and clamping mechanism 239 starts to operate. The two sets of drive mechanisms 2392 drive the two sets of clamping rods 2391 distributed in a "cross" shape. The two clamping rods 2391 in the same set will move towards each other according to the size and shape of the workpiece. During the movement, the clamping rods 2391 gradually approach the workpiece until they firmly clamp the workpiece, achieving accurate positioning of the workpiece and correcting the workpiece posture at the same time.

[0052] Once the workpiece is securely positioned, the storage mechanism of the unloading unit 23 will activate, removing the positioned workpiece from the positioning clamping mechanism 239 and neatly storing it according to the preset storage rules.

[0053] Then, the drive mechanism 2392 drives the two clamping rods 2391 in the same group to move in the opposite direction, so that the clamping rods 2391 return to the initial position, preparing for the positioning and clamping of the next machined workpiece. This cycle repeats to achieve continuous and automated production of workpieces.

[0054] Optionally, by Figures 1-4 As shown, in this embodiment, the feeding unit 21 includes a feeding bin 211, a conveyor belt 212, a loading tray 213, a first picking claw 214, a first multi-directional linear module 215, a second picking claw 216, and a second multi-directional linear module 217. The feeding bin 211 is used to store workpieces to be processed. The first picking claw 214 uses a vacuum suction cup to pick up the workpieces to be processed and moves them in three-dimensional space through the first multi-directional linear module 215 to transfer the workpieces to the conveyor belt 212 and deliver them to the picking position. The second picking claw 216 uses a vacuum suction cup to pick up the workpieces to be processed at the picking position and moves them in three-dimensional space through the second multi-directional linear module 217 to transfer the workpieces to the loading tray 213. With the above scheme, the feeding bin 211 stores a large number of workpieces to be processed during use, providing raw material guarantee for the subsequent feeding process.

[0055] Once the production line is started, the first multi-directional linear module 215 begins to operate, driving the first picking claw 214 to move in three-dimensional space, so that the first picking claw 214 accurately reaches the top of the workpiece to be picked in the feeding bin 211. Subsequently, the vacuum suction cup of the first picking claw 214 is activated, generating negative pressure and firmly picking up a workpiece to be processed.

[0056] Next, the first multi-directional linear module 215 drives the first picking claw 214 to move again, smoothly transferring the picked-up workpiece to the starting end of the conveyor belt 212 and stopping at a suitable position. At this time, the vacuum suction cup of the first picking claw 214 releases the negative pressure, and the workpiece is placed on the conveyor belt 212.

[0057] After receiving the workpiece, the conveyor belt 212 operates at a set speed to transport the workpiece to the picking position. When the workpiece reaches the picking position, the conveyor belt 212 stops running and waits for the second picking claw 216 to grab it.

[0058] Subsequently, the second multi-directional linear module 217 drives the second picking claw 216 to move above the workpiece at the picking position, and the vacuum suction cup of the second picking claw 216 is activated to pick up the workpiece to be processed.

[0059] Subsequently, the second multi-directional linear module 217 drives the second picking claw 216 to move in three-dimensional space, accurately transferring the workpiece to the designated position on the loading tray 213. After reaching the position, the vacuum suction cup of the second picking claw 216 releases the negative pressure, and the workpiece is placed stably on the loading tray 213, completing the entire feeding process of the feeding unit 21 and preparing for the loading unit 22 to pick up the workpiece.

[0060] As production continues, the feeding unit 21 repeats the above actions continuously to provide workpieces to be processed for subsequent processes, ensuring the continuous operation of the production line until a suitable number of workpieces are placed on the loading tray 213.

[0061] Optionally, by Figures 1-4 As shown, in this embodiment, the loading unit 22 includes a third picking claw 221 and a third multi-directional linear module 222, and the unloading unit 23 also includes an unloading tray 231, a loading platform 233, a receiving rack 234 fixed to the top of the loading platform 233, a fourth picking claw 235, a fourth multi-directional linear module 236, a fifth picking claw 237, and a fifth multi-directional linear module 238; wherein the third picking claw 221 uses a vacuum suction cup to pick up the workpiece to be processed on the loading tray 213 or the processed workpiece on the polishing machine assembly 1, and moves in three-dimensional space through the third multi-directional linear module 222 to transfer the workpiece to be processed to the polishing machine assembly 1 or to move the processed workpiece from the polishing machine assembly 1. The processed workpiece is fed to the unloading tray 231; the fourth picking claw 235 uses a vacuum suction cup to pick up the processed workpiece on the unloading tray 231, and moves in three-dimensional space through the fourth multi-directional linear module 236 to transfer the processed workpiece to the positioning stage 232; the fifth picking claw 237 uses a vacuum suction cup to pick up the processed workpiece on the loading stage 233, and moves in three-dimensional space through the fifth multi-directional linear module 238 to transfer the processed workpiece to the receiving rack 234 for storage. After adopting the above scheme, when using the workpiece, during loading, the third multi-directional linear module 222 drives the third picking claw 221 to move above the loading tray 213, and the vacuum suction cup of the third picking claw 221 is activated to pick up the loading tray 213.

[0062] Subsequently, the third multi-directional linear module 222 drives the third picking claw 221 to move precisely in three-dimensional space, transferring the loading tray 213 along with the workpiece to be processed on it to the processing position of the polishing machine assembly 1. After reaching the position, the vacuum suction cup of the third picking claw 221 releases the negative pressure, and the loading tray 213 is placed stably at the processing position, completing the loading operation.

[0063] After the workpiece is processed by the polishing machine assembly 1, the third multi-directional linear module 222 drives the third picking claw 221 to move to the processing position of the polishing machine assembly 1. The vacuum suction cup of the third picking claw 221 is activated to pick up the loading plate 213. Then, the third multi-directional linear module 222 drives the third picking claw 221 to move above the unloading plate 231. The vacuum suction cup releases the negative pressure and places the loading plate 213 on the unloading plate 231.

[0064] Subsequently, the fourth multi-directional linear module 236 drives the fourth picking claw 235 to move above the unloading tray 231. The vacuum suction cup of the fourth picking claw 235 is activated to pick up the processed workpiece on the unloading tray 231. Then, the fourth multi-directional linear module 236 drives the fourth picking claw 235 to move above the positioning table 232, releasing the processed workpiece and letting it fall onto the positioning table 232. At this time, the positioning and clamping mechanism 239 starts to work, and the driving mechanism 2392 drives the two sets of clamping rods 2391 distributed in a "cross" to move towards each other to clamp and position the workpiece.

[0065] After positioning is completed, the fourth picking claw 235 resets, and the fifth picking claw 237 moves. When the fifth picking claw 237 approaches the workpiece, the drive mechanism 2392 is activated to drive the two sets of clamping rods 2391, which are distributed in a "cross" shape, to move in opposite directions to move away from the workpiece. At the same time, the fifth picking claw 237 moves in three-dimensional space through the fifth multi-directional linear module 238 to pick up the positioned and processed workpiece from the positioning table 232 and transfer it to the loading table 233. The processed workpiece is then transferred to the designated position in the receiving rack 234. The vacuum suction cup releases the negative pressure, completing the storage of the processed workpiece.

[0066] As the production line continues to operate, the loading unit 22 and the unloading unit 23 repeatedly perform the above actions to achieve continuous loading, processing, transfer, positioning and storage of workpieces, ensuring the automated and efficient operation of the entire polishing machine production line.

[0067] Optionally, by Figures 1-3 , Figure 5 and Figure 6As shown, in this embodiment, the drive mechanism 2392 includes: a mounting plate 23921 fixed to the bottom surface of the positioning platform 232, a fixing frame 23922 symmetrically fixed to the bottom surface of the mounting plate 23921, a synchronous pulley 23923 rotatably mounted on the fixing frame 23922, a synchronous belt 23924 tensioned by the two synchronous pulleys 23923, fixing blocks 23925 fixed to both sides of the synchronous belt 23924, and a clamping rod 2391 fixed to the top of the fixing block 23925 and passing through a guide sliding hole 2 opened on the positioning platform 232 and the mounting plate 23921. 321 and a drive motor 23926 for driving the synchronous pulley 23923 to rotate. The drive motor 23926 is fixed to the fixed frame 23922. With the above solution, when it is necessary to position and clamp the processed workpiece on the positioning table 232, the drive motor 23926 starts, and its output shaft drives the synchronous pulley 23923 connected to it to rotate. Under the transmission action of the synchronous belt 23924, the other synchronous pulley 23923 rotates synchronously, so that the synchronous belt 23924 tensioned between the two synchronous pulleys 23923 circulates.

[0068] Since the fixing blocks 23925 are fixed on both sides of the timing belt 23924, when the timing belt 23924 is running, the fixing blocks 23925 on both sides will move in opposite directions under the drive of the timing belt 23924. At this time, the clamping rod 2391 fixed on the top of the fixing block 23925 will slide along the guide sliding hole 2321 opened on the positioning table 232 and the mounting plate 23921 as the fixing block 23925 moves.

[0069] For the two clamping rods 2391 in the same group, driven by the synchronous belt 23924, they will move towards each other, gradually approach and finally clamp the workpiece located on the positioning stage 232, thus completing the positioning and clamping operation of the workpiece.

[0070] When it is necessary to release the workpiece, the drive motor 23926 rotates in the opposite direction. Through the transmission of the synchronous pulley 23923 and the synchronous belt 23924, the fixed block 23925 and the clamping rod 2391 move in the opposite direction. That is, the two clamping rods 2391 in the same group move away from each other, thereby releasing the workpiece and preparing for the next positioning and clamping.

[0071] Two sets of clamping rods 2391 arranged in a "cross" configuration are independently driven by corresponding drive mechanisms 2392, which can clamp and position the workpiece from different directions, ensuring that the workpiece is accurately and stably positioned on the positioning table 232, providing a reliable guarantee for subsequent transfer and storage processes.

[0072] Optionally, by Figures 1-3As shown, in this embodiment, the loading tray 213 is rotatably mounted on the machine body 20 and driven by a servo motor fixed inside the machine body 20. The unloading tray 231 is rotatably mounted on the machine body 20 and driven by a servo motor fixed inside the machine body 20. The loading platform 233 is provided with multiple sets of receiving racks 234 evenly distributed along the circumferential direction. The loading platform 233 is rotatably mounted on the machine body 20 and driven by a servo motor fixed inside the machine body 20. With the above scheme, when the second picking claw 216 transfers the workpiece to be processed to the loading tray 213, the servo motor drives the loading tray 213 to rotate at a preset angle and speed, accurately rotating the position carrying the workpiece to the range that the third picking claw 221 can easily grasp. In this way, multiple workpieces can be continuously supplied on the loading tray 213, improving the loading efficiency and avoiding the impact on the production line rhythm due to untimely supply from a single position. Multiple workpieces can be loaded on the loading tray 213 at the same time.

[0073] The unloading tray 231 is also driven to rotate by a servo motor inside the machine body 20. Similar to the working principle of the loading tray 213, the rotation function ensures the reliability of the fourth picking claw 235 in picking up the workpiece, providing a basic guarantee for subsequent neat storage.

[0074] The loading platform 233 rotates under the drive of a servo motor. Its top is equipped with multiple sets of receiving racks 234 evenly distributed along the circumference. After the fifth picking claw 237 transfers the processed workpiece to one of the receiving racks 234 for storage, the servo motor drives the loading platform 233 to rotate by a preset angle, so that the next empty receiving rack 234 can be moved into the working range of the fifth picking claw 237, making it convenient for the fifth picking claw 237 to continue placing workpieces. This design can make full use of the space of the loading platform 233, realize the continuous storage of multiple receiving racks 234, improve storage efficiency, reduce the frequency of production line shutdown due to full receiving racks 234, and ensure the continuous and stable operation of the entire production line.

[0075] Example 2

[0076] See also the appendix Figure 7 This embodiment is largely the same as Embodiment 1, except that the positioning clamping mechanism 239 in this embodiment adopts a different scheme.

[0077] Specifically, in this embodiment, the positioning and clamping mechanism 239 includes two sets of adjacent or oppositely distributed positioning clamps 2395. A placement groove 2322 for placing workpieces is provided on the top surface of the positioning platform 232, and a guide hole 2323 adapted to the positioning clamp 2395 is provided on the positioning platform 232 at a position corresponding to the placement groove 2322. The positioning clamp 2395 can slide along the guide hole 2323 to move closer to or away from the workpiece.

[0078] In addition, a fixing plate 2393 is fixed on the bottom surface of the positioning table 232, and a dual-axis cylinder 2394 is installed on the fixing plate 2393. The piston rod of the dual-axis cylinder 2394 is fixedly connected to the positioning clamping plate 2395 to drive the positioning clamping plate 2395 to move closer to or away from the workpiece. At the same time, a rubber block 2396 is provided on the clamping surface of the positioning clamping plate 2395. With the above scheme, when in use, the fourth picking claw 235 places the processed workpiece in the placement groove 2322. The placement groove 2322 can play a preliminary limiting role for the workpiece and avoid large displacement of the workpiece in the initial placement stage.

[0079] Subsequently, the dual-axis cylinder 2394 installed on the fixed plate 2393 is activated. The piston rod of the dual-axis cylinder 2394 will extend or retract accordingly. Since the piston rod is fixedly connected to the positioning clamping plate 2395, under the drive of the piston rod, the two sets of adjacent or oppositely distributed positioning clamping plates 2395 will slide along the guide holes 2323 on the positioning platform 232 that are adapted to each other.

[0080] When the piston rod extends, the positioning clamp 2395 moves towards the workpiece along the guide hole 2323. As the movement continues, the two sets of positioning clamps 2395 will gradually come into contact with the workpiece. At this time, the rubber block 2396 on the clamping surface of the positioning clamp 2395 will first come into contact with the workpiece. The rubber block 2396 has a certain elasticity and friction. On the one hand, it can avoid hard contact between the positioning clamp 2395 and the workpiece, prevent the workpiece surface from being scratched or crushed, and play a role in protecting the workpiece. On the other hand, its good friction can enhance the clamping stability of the workpiece.

[0081] Once the positioning clamp 2395 firmly clamps the workpiece, the dual-axis cylinder 2394 stops operating, and the workpiece is stably positioned in the placement slot 2322, achieving precise positioning and posture correction of the workpiece.

[0082] Finally, when the fifth picking claw 237 approaches the workpiece, the dual-axis cylinder 2394 is activated to retract the positioning clamp 2395 to its initial position. At the same time, the fifth picking claw 237 moves to pick up the positioned processed workpiece from the positioning table 232 and transfer it to the loading table 233. The processed workpiece is then transferred to the designated position in the receiving rack 234. The vacuum suction cup releases the negative pressure, completing the storage of the processed workpiece.

[0083] It should be noted that the electrical components involved in this utility model are all commercially available conventional equipment with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0084] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0085] Components not described in detail in this article are existing technologies.

[0086] The working principle and usage process of this utility model: When the polishing machine of this utility model is in use, the feeding bin 211 stores a large number of workpieces to be processed, providing raw material guarantee for the subsequent feeding process;

[0087] Once the production line is started, the first multi-directional linear module 215 begins to operate, driving the first picking claw 214 to move in three-dimensional space, so that the first picking claw 214 accurately reaches the top of the workpiece to be picked in the feeding bin 211. Then, the vacuum suction cup of the first picking claw 214 is activated, generating negative pressure and firmly picking up a workpiece to be processed.

[0088] Next, the first multi-directional linear module 215 drives the first picking claw 214 to move again, smoothly transferring the picked-up workpiece to the starting end of the conveyor belt 212 and stopping at a suitable position. At this time, the vacuum suction cup of the first picking claw 214 releases the negative pressure, and the workpiece is placed on the conveyor belt 212.

[0089] After receiving the workpiece, the conveyor belt 212 runs at a set speed to transport the workpiece to the picking position. When the workpiece reaches the picking position, the conveyor belt 212 stops running and waits for the second picking claw 216 to grab it. Then, the second multi-directional linear module 217 drives the second picking claw 216 to move above the workpiece at the picking position. The vacuum suction cup of the second picking claw 216 is activated to pick up the workpiece to be processed.

[0090] Then, the second multi-directional linear module 217 drives the second picking claw 216 to move in three-dimensional space, accurately transferring the workpiece to the designated position of the loading tray 213. After reaching the position, the vacuum suction cup of the second picking claw 216 releases the negative pressure, and the workpiece is placed stably on the loading tray 213, completing the entire feeding process of the feeding unit 21 and preparing for the loading unit 22 to pick up the workpiece.

[0091] During loading, the third multi-directional linear module 222 drives the third picking claw 221 to move above the loading plate 213, and the vacuum suction cup of the third picking claw 221 is activated to pick up the loading plate 213.

[0092] Subsequently, the third multi-directional linear module 222 drives the third picking claw 221 to move precisely in three-dimensional space, transferring the loading tray 213 along with the workpiece to be processed on it to the processing position of the polishing machine assembly 1. After reaching the position, the vacuum suction cup of the third picking claw 221 releases the negative pressure, and the loading tray 213 is placed stably in the processing position, completing the loading operation.

[0093] After the workpiece is processed by the polishing machine assembly 1, the third multi-directional linear module 222 drives the third picking claw 221 to move to the processing position of the polishing machine assembly 1. The vacuum suction cup of the third picking claw 221 is activated to pick up the loading plate 213. Then, the third multi-directional linear module 222 drives the third picking claw 221 to move above the unloading plate 231. The vacuum suction cup releases the negative pressure and places the loading plate 213 on the unloading plate 231.

[0094] Subsequently, the fourth multi-directional linear module 236 drives the fourth picking claw 235 to move above the unloading tray 231. The vacuum suction cup of the fourth picking claw 235 is activated to pick up the processed workpiece on the unloading tray 231. Then, the fourth multi-directional linear module 236 drives the fourth picking claw 235 to move above the positioning table 232, releasing the processed workpiece and letting it fall onto the positioning table 232. At this time, the positioning and clamping mechanism 239 starts to work. The driving mechanism 2392 drives two sets of clamping rods 2391 distributed in a "cross" to move towards each other, clamping and positioning the workpiece, while simultaneously correcting the workpiece's posture.

[0095] After positioning is completed, the fourth picking claw 235 moves again to pick up the positioned processed workpiece from the positioning table 232 and transfer it to the loading table 233, and then transfer the processed workpiece to the designated position in the receiving rack 234. The vacuum suction cup releases the negative pressure to complete the storage of the processed workpiece.

[0096] As the production line continues to operate, the loading unit 22 and the unloading unit 23 repeatedly perform the above actions to achieve continuous loading, processing, transfer, positioning and storage of workpieces, ensuring the automated and efficient operation of the entire polishing machine production line.
