Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically to an automatic workpiece flipping device for a four-station environmentally friendly intelligent polishing machine. Background Technology

[0002] Polishing machines use high-speed rotating polishing wheels or abrasive belts, along with polishing wax, polishing fluid, or other media, to remove tool marks, oxide scale, or injection-molded burrs from workpiece surfaces in a short time, achieving different finishes such as mirror, matte, or brushed. With the rapid pace of product updates in the consumer market, manufacturers have placed higher demands on polishing efficiency, consistency, and yield rates, leading to the development of multi-station, continuous-operation rotary polishing machines.

[0003] However, existing four-station rotary polishing machines generally employ two solutions for workpieces requiring double-sided polishing: manual flipping or independent robotic flipping. Manual flipping is not only labor-intensive but also poses a health threat to operators due to the dusty environment. While independent robotic flipping can automatically complete the flipping, it requires additional equipment such as a six-axis robot, a vision positioning system, and safety railings around the rotary table, resulting in increased footprint, significantly higher costs, and more complex control logic.

[0020] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0021] Please see Figure 1-5 An automatic workpiece flipping device for a four-station environmentally friendly intelligent polishing machine includes a processing table 1, a dustproof shell 2 fixed on the top of the processing table 1, a first motor 3 fixed on the bottom of the processing table 1, an output shaft of the first motor 3 passing through the processing table 1 and fixed to a rotating disk 4, four clamping and flipping mechanisms 5 fixed on the top of the rotating disk 4, a polishing mechanism 6 fixed on the top of the processing table 1, a dust removal mechanism 7 set on the top of the dustproof shell 2, a door 8 hinged to the surface of the dustproof shell 2, a controller 9 fixed on the surface of the dustproof shell 2, and transparent observation windows 10 fixed on both the front and rear surfaces of the dustproof shell 2.

[0022] Through the above technical solution, the processing table 1 serves as the basic frame of the whole machine, forming a semi-enclosed space through the dustproof shell 2. The first motor 3 drives the rotating disk 4 to rotate intermittently. Every 90 degrees of rotation, the next clamping and flipping mechanism 5 is sent to the polishing mechanism 6 station. The dust removal mechanism 7 continuously sucks in the negative pressure at the top, causing the dust to rise with the airflow and be collected. The box door 8 can be opened for inspection and maintenance and to put in and take out workpieces. The transparent observation window 10 allows real-time viewing of the internal working conditions. The controller 9 centrally processes all signals to achieve rhythmic production. This device integrates rotation, polishing, and dust removal functions into the same table, occupying a compact space. The operator can monitor the entire process through the observation window and start operating quickly as soon as the door is opened, significantly reducing labor intensity and improving the environmental friendliness of the workshop.

[0023] The clamping and flipping mechanism 5 includes a vertical plate 501, the bottom of which is fixedly connected to the top of the rotating disk 4. A rotary cylinder 502 is fixedly mounted on the surface of the vertical plate 501. A pneumatic gripper 503 is fixedly mounted on the surface of the moving part of the rotary cylinder 502. A clamping plate 504 is fixedly mounted on the surface of the moving part of the pneumatic gripper 503.

[0024] Through the above technical solution, the vertical plate 501 in the clamping and flipping mechanism 5 lifts the rotary cylinder 502 away from the top surface of the rotary disk 4. After receiving the signal, the rotary cylinder 502 drives the pneumatic gripper 503 and its clamping plate 504 to rotate 180 degrees as a whole, so that the workpiece is flipped. After flipping, the pneumatic gripper 503 continues to hold the workpiece, ensuring that the positioning reference remains unchanged when polishing the second side. Automatic flipping is completed through the rotation-reset cycle of the rotary cylinder 502. No additional robotic arm is required. The structure is simple and reliable. Maintenance only requires replacing the seals. The flipping angle is constant, the workpiece has high repeatability and positioning accuracy, significantly reduces manual intervention and downtime, and improves the overall production line cycle time.

[0025] Two extension blocks 505 are fixed to the surface of the clamping plate 504. A lead screw 506 is rotatably connected to the surface of the extension block 505. One end of the lead screw 506 passes through the extension block 505 and is fixed with a handwheel. A sliding sleeve 507 is threaded to the surface of the extension block 505. A sliding groove 508 is opened on the surface of the clamping plate 504. A lateral clamping block 509 is fixed to the surface of the sliding sleeve 507. The lateral clamping block 509 is slidably connected to the surface of the sliding groove 508.

[0026] With the above technical solution, the extension block 505 is fixed to the clamping plate 504, the handwheel drives the lead screw 506 to rotate, and the sliding sleeve 507 moves along the axial direction of the lead screw 506 under the action of the thread, which drives the lateral clamping block 509 to slide in the sliding groove 508 of the clamping plate 504, thereby adjusting the clamping width to adapt to workpieces of different sizes.

[0027] The polishing mechanism 6 includes an extension frame 601, which is fixed to the top of the processing table 1. A lifting cylinder 602 is fixed to the top of the extension frame 601. One end of the lifting cylinder 602 passes through the extension frame 601 and is fixed to a mounting plate 603. A linear module 604 is fixed to the bottom of the mounting plate 603. A mounting frame 605 is fixed to the surface of the moving part of the linear module 604. A pushing cylinder 606 is fixed to the top of the mounting frame 605. A sliding plate 607 is fixed to one end of the pushing cylinder 606. A second motor 608 is fixed to the top of the sliding plate 607. The output shaft of the second motor 608 passes through the sliding plate 607 and is fixed to a connecting shaft 609. A long through groove is opened on the surface of the mounting frame 605 to accommodate the connecting shaft 609. A polishing block 610 is fixed to the bottom of the connecting shaft 609.

[0028] Through the above technical solution, the extension frame 601 of the polishing mechanism 6 is fixed to the processing table 1, the lifting cylinder 602 drives the mounting plate 603 to move up and down to achieve height adjustment, the linear module 604 drives the mounting frame 605 to move horizontally, and pushes the cylinder 606 to drive the sliding plate 607 to feed slightly. The second motor 608 makes the polishing block 610 rotate at high speed through the connecting shaft 609. The long through groove provides the stroke margin, so that the polishing block 610 can accurately fit the workpiece surface in three-dimensional space.

[0029] The dust removal mechanism 7 includes a collection shell 701 and an exhaust fan 702. Both the collection shell 701 and the exhaust fan 702 are fixed to the top of the dustproof shell 2. The exhaust fan 702 is connected to the collection shell 701. An exhaust pipe 703 is connected to the surface of the collection shell 701. One end of the exhaust pipe 703 is connected to the top of the dustproof shell 2. A cleaning door 704 is hinged to the top of the collection shell 701. A connecting ring 705 is fixed to the inner wall of the collection shell 701. A filter element 706 is threadedly connected to the inner wall of the connecting ring 705.

[0030] Through the above technical solution, the exhaust fan 702 of the dust removal mechanism 7 establishes negative pressure in the collection shell 701, and the exhaust pipe 703 guides the suspended dust in the dustproof shell 2 into the collection shell 701. The dust-laden airflow is filtered by the filter element 706 and then discharged cleanly. The connecting ring 705 adopts a threaded quick-release design, and the filter element 706 can be unscrewed out for cleaning by opening the cleaning door 704.

[0031] The top of the extension frame 601 has two guide rods 611 that slide through it. The bottom of the guide rods 611 is fixedly connected to the top of the mounting plate 603. The top of the mounting frame 605 has two slide rails fixedly attached, and the surface of the sliding plate 607 is slidably connected to the surface of the slide rails.

[0032] Through the above technical solution, the guide rod 611 slides with the extension frame 601 during the extension and retraction of the lifting cylinder 602 to prevent the mounting plate 603 from swaying. The slide rail and the sliding plate 607 cooperate to transmit the thrust of the pushing cylinder 606 in a straight line, reducing the impact of lateral force on the connecting shaft 609.

[0033] A circular slide rail 11 is fixed on the top of the processing table 1. A slider 12 is slidably connected to the surface of the circular slide rail 11. The top of the slider 12 is fixedly connected to the bottom of the rotary disk 4. The first motor 3 is a servo motor and a brake device is installed at the tail.

[0034] Through the above technical solution, the circular slide rail 11 and the slider 12 form a rolling support to share the weight of the rotating disk 4 and the workpiece, avoid the radial bending moment of the output shaft of the first motor 3, and the brake device locks the motor shaft at the moment of stopping to prevent inertial slippage.

[0035] Working principle: First, open the box door 8, then the operator places the workpiece into the clamping and flipping mechanism 5 located at the loading station. The pneumatic gripper 503 clamps the workpiece with the clamping plate 504. The first motor 3 drives the rotating disk 4 to rotate 90 degrees along the circular slide rail 11, so that the workpiece enters below the polishing mechanism 6. The lifting cylinder 602 descends, and the linear module 604 and the pushing cylinder 606 work together to make the polishing block 610 fit against the surface of the workpiece. The second motor 608 rotates at high speed and continuously feeds to complete the first side polishing. Then the first motor 3 rotates 90 degrees again, and the workpiece reaches the flipping station. The rotating cylinder 5... 02 drives the pneumatic gripper 503 to rotate 180 degrees. After the workpiece is flipped, it enters the polishing station again with the rotating disk 4 for a second polishing. Throughout the process, the exhaust fan 702 runs continuously. Dust enters the collection shell 701 through the exhaust pipe 703 and is filtered by the filter element 706. The transparent observation window 10 monitors in real time, and the controller 9 coordinates the rhythm of each actuator. After the workpiece has completed double-sided polishing, the box door 8 can be opened manually to remove the workpiece. This device achieves continuous double-sided polishing and simultaneous environmentally friendly dust removal, solving the problems of traditional flipping requiring an external robotic arm, large footprint, high cost, and dust escape.
