[0052] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0053] Example: See Figure 1 - Fig. 9 , a component assembly processing platform for metal product processing, comprising a base 1 and a laser cutting machine 2, and also comprising:

[0054] An auxiliary support frame 3 is installed on the top of the base 1, and a whole metal plate is placed on the top of the auxiliary support frame 3;

[0055] The lifting frame 4 is arranged on the inner side of the auxiliary support frame 3. Four cylinders 5 are installed inside the base 1. The cylinders 5 are located at the corners of the base 1. The elongated ends of the cylinders 5 are fixedly connected with connecting blocks 6. The top of the connecting block 6 is fixedly connected with the bottom of the lifting frame 4. In the initial state, the upper edge of the auxiliary support frame 3, the upper edge of the lifting frame 4 and the upper edge of the sword grid bar 31 are at the same horizontal height;

[0056] By controlling the air cylinder 5, the lifting frame 4 can be driven to rise and fall, thereby driving the supporting mechanisms inside the lifting frame 4 to rise and fall synchronously. When the lifting frame 4 descends, the metal plate is still located on the top of the auxiliary supporting frame 3, and only the small parts cut off will descend with the supporting mechanism.

[0057] The supporting mechanism is provided with multiple ones and all are installed inside the lifting frame 4, which is used to support the small parts cut by the laser. The supporting mechanism includes two fixed blocks 7 and multiple sword bars 31 fixed between the two fixed blocks 7; the insides of the two fixed blocks 7 are fixed with driven shafts 8, and the driven shafts 8 are rotatably connected to the inside of the lifting frame 4;

[0058] The small parts cut from the whole metal plate are supported by the sword bars 31. When the lifting frame 4 descends, the sword bars 31 and the small parts on the top of the sword bars 31 are driven to move downward synchronously through the driven shaft 8 and the fixed block 7. In addition, when the driven shaft 8 is driven to rotate, the sword bars 31 are driven to flip 180° synchronously through the fixed block 7 to guide the small parts on the top of the sword bars 31 downward.

[0059] A directional material guiding mechanism is installed inside the base 1 and is used to drive the small parts on the supporting mechanism to move in a set direction after the lifting frame 4 drives the supporting mechanism to move downward. The directional material guiding mechanism includes two screw rods 9 rotatably connected to the inside of the base 1, a driving block 10 screwed to the outside of the two screw rods 9 and a lifting block 11 arranged above the driving block 10; a plurality of hydraulic cylinders 12 are installed inside the driving block 10, and the extended end of the hydraulic cylinder 12 is fixedly connected to the bottom of the lifting block 11; a plurality of push blocks 13 are fixedly connected to the top of the lifting block 11, and the distance between two adjacent sword bars 31 is the same as the width of the push block 13. A motor 14 is installed on the outer wall of one side of the base 1, and one end of the two screw rods 9 extends to the outside of the base 1, and the output shaft of the motor 14 is connected to the screw rod 9 through a transmission member 15; the transmission member 15 includes two synchronous wheels fixedly sleeved on the outside of the output shaft of the motor 14 and the outside of the screw rod 9, and a synchronous belt connected to the outside of the two synchronous wheels;

[0060] Whenever small parts in one-third of the area are cut out of the entire metal plate, the lifting frame 4 is first driven to rise and fall by controlling the air cylinder 5, thereby driving the small parts on the top of the sword grating 31 to descend synchronously, and then the motor 14 is controlled to drive its output shaft to rotate forward, and through the transmission connection of the two transmission members 15, the two screw rods 9 are driven to rotate synchronously, thereby driving the driving block 10 to move to the right, thereby driving the multiple push blocks 13 to move to the right synchronously through each hydraulic cylinder 12 and the lifting block 11. When the push block 13 moves to the bottom of the sword grating 31, the hydraulic cylinder 12 is controlled to extend and drive The lifting block 11 and multiple push blocks 13 move upward synchronously, so that each push block 13 abuts between two adjacent sword bars 31, and the upper edge of the push block 13 is higher than the upper edge of the sword bar 31, and then continues to drive the push block 13 to move right, thereby pushing the small parts on the top of the sword bar 31 to the right, until the small parts are pushed to the right side of the top of the sword bar 31, and then control the hydraulic cylinder 12 to drive the push block 13 to move down and reset, and control the motor 14 to drive its output shaft to reverse, thereby driving the drive block 10 to move left and reset through the screw rod 9, and then driving the push block 13 to reset synchronously.

[0061] The transfer mechanism is connected to the support mechanism and is used to transfer the small parts that have moved in the set direction downward. The transfer mechanism includes a baffle 16 installed on the inner wall of one side of the base 1, a plurality of racks 17 fixedly connected to the top of the baffle 16, and a plurality of gears 18 respectively fixedly sleeved on the outside of the plurality of driven shafts 8; the gears 18 cooperate with the racks 17; a plurality of through slots 19 are opened through the interior of the lifting frame 4, and the through slots 19 are used to pass the racks 17;

[0062] After the push block 13 is reset by moving to the left, the lifting frame 4 and the sword bars 31 are driven to continue to move downward by controlling the cylinder 5. In this process, the gear 18 is meshed with the rack 17, driving the driven shaft 8 to rotate 180°, and then driving the multiple sword bars 31 to flip 180° through the fixed block 7. Among them, when the entire support mechanism flips 90°, that is, when the support mechanism stands up, the distance between the two adjacent support mechanisms is large, and the small parts fall from the gap between the two support mechanisms to the top of the right side of the first belt conveyor mechanism 20, that is, the area inside the first limit plate 22 and the first guide platform 32;

[0063] After the small parts on the top of the sword bar 31 are transferred to the top of the first belt conveyor mechanism 20, the lifting frame 4 and the sword bar 31 are driven to move up and reset by controlling the cylinder 5. In this process, the sword bar 31 is driven to rotate and reset through the meshing effect between the gear 18 and the rack 17.

[0064] A primary polishing mechanism is arranged below the supporting mechanism, and is used to receive the small parts transferred downward at a limited position, and drive the small parts to be automatically laid flat on the top thereof and polish the small parts on one side. The primary polishing mechanism includes a first belt conveyor mechanism 20 installed inside the base 1 and a plurality of first polishing brush rollers 21 installed inside the base 1; the plurality of first polishing brush rollers 21 are all located above the first belt conveyor mechanism 20; a first limit plate 22 is also fixedly connected inside the base 1, the first limit plate 22 is located above the first belt conveyor mechanism 20, and the first limit plate 22 is located on the side of the first polishing brush roller 21 close to the baffle 16, and the input end of each first polishing brush roller 21 is connected to a driving motor, and the driving motor is installed on the back of the base 1; a first material guide table 32 is fixedly connected to the outer wall of the baffle 16 on the side close to the first polishing brush roller 21;

[0065] After the small parts fall into the area between the first limit plate 22 and the first material guide platform 32, the first belt conveyor mechanism 20 is controlled to drive the small parts on its top to move to the left. Through the limiting effect of the first limit plate 22, the small parts can only pass through the bottom of the first limit plate 22 in a single layer and will not be stacked together, thereby ensuring that each small part can be polished subsequently. When the small parts pass through the bottom of each first polishing brush roller 21 in turn, the rotating first polishing brush roller 21 polishes the top of each small part to remove the oxide layer on the surface of the small parts and the burrs generated by laser cutting.

[0066] The face-changing mechanism is arranged on one side of the primary polishing mechanism, and automatically turns over the small parts after single-side polishing. The face-changing mechanism includes a vertical plate 23 installed inside the base 1, a direction-changing platform 24 fixed to the top of the vertical plate 23, and a second material guide platform 25 fixed to the bottom of the vertical plate 23; the vertical plate 23 is located on the side of the first belt conveyor mechanism 20 away from the first material guide platform 32;

[0067] After the small parts are polished once, they continue to move to the left. When the top of one end of the small parts abuts against the inclined bottom of the turning table 24, the small parts begin to be driven to move obliquely downward. Then, the bottom end of the current small parts abuts against the inclined surface of the top of the second material guide table 25, and then slides downward along the inclined surface of the top of the second material guide table 25. When the bottom end of the small parts contacts the top of the second belt conveyor mechanism 26, the second belt conveyor mechanism 26 drives the small parts to move to the right. At this time, the surface changing process of the small parts is completed, that is, the top of the small parts when polished at the top of the first belt conveyor mechanism 20 becomes the bottom when transferred to the top of the second belt conveyor mechanism 26, and the unpolished bottom becomes the top.

[0068] A secondary polishing mechanism is arranged below the primary polishing mechanism and is used for secondary polishing of the small parts after turning over. The secondary polishing mechanism includes a second belt conveying mechanism 26 installed inside the base 1 and a plurality of second polishing brush rollers 27 installed inside the base 1; the second polishing brush rollers 27 are located above the second polishing brush rollers 27, and the input ends of the second polishing brush rollers 27 are connected to drive motors, and the drive motors are installed on the back of the base 1; the second belt conveying mechanism 26 is located below the second material guide platform 25; a second limit plate 28 is also fixedly connected to the inside of the base 1, and the second limit plate 28 is located above the second belt conveying mechanism 26 and between the second material guide platform 25 and the second polishing brush rollers 27; a discharge port 29 is provided on the outer wall on the other side of the base 1, and a third material guide platform 30 is installed inside the discharge port 29;

[0069] When the second belt conveyor mechanism 26 drives the small parts after the face change to move to the right, the second limiting plate 28 continues to limit the small parts, so that the small parts pass through the bottom of the second limiting plate 28 in a single layer. When the second small parts pass through the bottom of each second polishing brush roller 27 in turn, each second polishing brush roller 27 performs a secondary polishing treatment on each small part. After the secondary polishing treatment, the small parts are continued to be conveyed to the right by the second belt conveyor mechanism 26. When the small parts are conveyed to the right end of the second belt conveyor mechanism 26, the small parts automatically fall to the top of the third guide table 30 and are discharged through the discharge port 29 along the third guide table 30. Therefore, the small parts obtained by laser cutting are automatically unloaded after passing the polishing process, and there is no need to manually pick out the cut small parts one by one from the top of the sword bar 31.

[0070] Working principle: When in use, the staff places the whole metal plate on the top of the auxiliary support frame 3, controls the laser cutting machine 2 to cut the left third area of ​​the metal plate in sequence, and obtains multiple small parts, and then controls the cylinder 5 to drive the lifting frame 4 to rise and fall, thereby driving the small parts on the top of the sword grid bar 31 to descend synchronously, and then controls the motor 14 to drive its output shaft to rotate forward, and through the transmission connection of the two transmission parts 15, drives the two lead screws 9 to rotate synchronously, and then drives the driving block 10 to move to the right, thereby driving the multiple push blocks 13 to move to the right synchronously through each hydraulic cylinder 12 and the lifting block 11. When the push block 13 moves to the bottom of the sword grid bar 31, the lifting block 11 and the multiple push blocks 13 are driven to move upward synchronously by controlling the extension of the hydraulic cylinder 12. Make each push block 13 respectively abut between two adjacent sword bars 31, and the upper edge of the push block 13 is higher than the upper edge of the sword bar 31, and then continue to drive the push block 13 to move right, so as to push each small part on the top of the sword bar 31 to the right, until the small part is pushed to the right side of the top of the sword bar 31, and then control the hydraulic cylinder 12 to drive the push block 13 to move down and reset, and control the motor 14 to drive its output shaft to reverse, so as to drive the drive block 10 to move left and reset through the screw rod 9, and then drive the push block 13 to reset synchronously, and then control the cylinder 5 to drive the lifting frame 4 and the sword bar 31 to continue to move downward. In this process, the gear 18 is meshed with the rack 17, driving the driven shaft 8 to rotate 180°, and then driving the multiple sword bars 31 to flip 180° through the fixed block 7. When the entire support mechanism flips 90°, that is, when the support mechanism stands up, the distance between the two adjacent support mechanisms is larger, and the small parts fall from the gap between the two support mechanisms to the top of the right side of the first belt conveyor mechanism 20, that is, inside the area between the first limiting plate 22 and the first material guide platform 32. The first belt conveyor mechanism 20 is controlled to drive the small parts on its top to move to the left. Through the limiting effect of the first limiting plate 22, the small parts can only pass through the bottom of the first limiting plate 22 in a single layer, and will not be stacked together, thereby ensuring that each small part can be polished later. When the small parts pass through the bottom of each first polishing brush roller 21 in turn, the rotating first polishing brush roller 21 polishes the top of each small part. Polishing treatment is performed to remove the oxide layer on the surface of the small parts and the burrs generated by laser cutting. After the small parts are polished once, they continue to move to the left. When the top of one end of the small parts abuts against the inclined bottom of the turning platform 24, the small parts are driven to move obliquely downward. Then, the bottom end of the current small parts abuts against the inclined surface of the top of the second material guide platform 25, and then slides downward along the inclined surface of the top of the second material guide platform 25. When the bottom end of the small parts contacts the top of the second belt conveyor mechanism 26, the second belt conveyor mechanism 26 drives the small parts to move to the right. At this time, the surface changing treatment of the small parts is completed, that is, the top of the small parts when polished at the top of the first belt conveyor mechanism 20 becomes the bottom when transferred to the top of the second belt conveyor mechanism 26.The unpolished bottom becomes the top, and when the second belt conveyor mechanism 26 drives the small parts after the face change to move to the right, the second limit plate 28 continues to limit the small parts, so that the small parts pass through the bottom of the second limit plate 28 in a single layer. When the second small parts pass through the bottom of each second polishing brush roller 27 in turn, each second polishing brush roller 27 performs a secondary polishing process on each small part. After the secondary polishing process, the small parts are continued to be conveyed to the right by the second belt conveyor mechanism 26. When the small parts are conveyed to the right end of the second belt conveyor mechanism 26, the small parts automatically fall to the top of the third guide table 30 and are discharged through the discharge port 29 along the third guide table 30. Therefore, the small parts obtained by laser cutting are automatically unloaded after passing the polishing process, and there is no need to manually pick out the cut small parts one by one from the top of the sword bar 31.
