Description

Technical Field

[0001] This utility model relates to the field of loading and unloading technology, specifically an automatic loading and unloading device for a milling machine. Background Technology

[0002] A milling machine is a piece of equipment used for high-precision, high-efficiency grinding or polishing. It is mainly used for processing thin and brittle metals or non-metals such as piezoelectric crystals, optical crystals, optical glass, sapphire, ceramic wafers, neodymium iron boron wafers, silicon wafers, quartz wafers, piston rings, molybdenum wafers, cemented carbide cutting tools, ferrite, and lithium niobate. Its working principle typically involves the upper and lower plates rotating in opposite directions, while the workpiece undergoes planetary motion within a planetary gear, resulting in simultaneous and uniform grinding or polishing of both the upper and lower surfaces of the workpiece. The application of automatic loading and unloading in milling machines can significantly improve production efficiency, reduce manual intervention, lower labor intensity, and simultaneously improve processing accuracy and product quality. Existing automatic loading and unloading devices use a robotic arm structure in conjunction with a suction cup structure to pick up the workpiece to be processed and deliver it to the milling area. After milling, the workpiece is retrieved and stored using the same robotic arm structure and suction cup structure.

[0003] However, after milling, some abrasive, debris or other substances remain on the surface of the workpiece. These residues do affect the adsorption effect of the automatic loading and unloading device, which causes the workpiece to fall off when the robot moves the workpiece, damaging the workpiece and causing losses. Therefore, an automatic loading and unloading device for milling machines is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic loading and unloading device for milling and grinding machines, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic loading and unloading device for a milling machine, comprising:

[0006] The base has a storage cavity at its upper end and a side strip at its left end.

[0009] The third drive motor is located on the front right side of the base. A rotating rod is installed at the output end of the third drive motor. A fifth drive motor is installed on both the front and rear sides of the rotating rod. A self-cleaning adsorption mechanism is installed at the output end of the fifth drive motor and the front lower end of the slider. The self-cleaning adsorption mechanism includes a fixing block.

[0010] An electric telescopic rod is installed inside a fixed block. One end of the electric telescopic rod has a three-way housing, the output end of which has a suction cup. The upper end of the three-way housing has a suction pipe, inside which is a first solenoid valve. One end of the suction pipe has a vacuum generator. The lower end of the three-way housing has a blowing pipe, inside which is a second solenoid valve. A high-speed fan is installed on one side of the blowing pipe.

[0012] Preferably, a clamping block is provided at one end of the electric push rod, and the clamping block is connected to the electric push rod. The electric push rod is used to control the clamping block to clamp the workpiece.

[0013] Preferably, a rack is provided at the lower end of the side strip, and a first drive motor is provided inside the side sliding shell near the rack. A drive gear is installed at the output end of the first drive motor, and the drive gear is connected to the rack for transmission. The first drive motor is used to drive the drive gear.

[0014] Preferably, a second drive motor is provided on one side of the upper end of the L-shaped side frame, and a drive screw is installed at the output end of the second drive motor.

[0017] This invention utilizes a three-way housing with two solenoid valves to open and close the suction pipe and the blowing pipe. When a freshly milled workpiece needs to be adsorbed, the first solenoid valve of the suction pipe is closed, and the second solenoid valve of the blowing pipe is opened. A high-speed blower generates a high-speed airflow that passes through the three-way housing and is ejected from the suction cup to clean the workpiece, thereby cleaning the adsorption area on the outside of the workpiece. After cleaning, the second solenoid valve of the blowing pipe is closed and the first solenoid valve of the suction pipe is opened, activating the vacuum generator to adsorb the workpiece through the suction cup.

[0029] An electric telescopic rod 14 is installed inside the fixed block 13. A three-way housing 15 is installed at one end of the electric telescopic rod 14.

A high-speed fan 22 is installed on one side of the air blowing pipe 18. The output end of the fifth drive motor 33 and the lower front side of the slider 12 are both connected to the fixed block 13.

[0030] Please see Figure 1 The clamping mechanism includes a round box 30, and electric push rods 31 are provided on both sides of the inside of the round box 30, and the electric push rods 31 are connected to the round box 30.

[0031] Please see Figure 1 The electric push rod 31 has a clamping block 32 at one end, and the clamping block 32 is connected to the electric push rod 31. The electric push rod 31 is used to control the clamping block 32 to clamp the workpiece.

[0032] Please see Figure 1 and Figure 2 A rack 5 is provided at the lower end of the side strip 4. A first drive motor 6 is provided inside the side sliding housing 8 near the rack 5. A drive gear 7 is installed at the output end of the first drive motor 6, and the drive gear 7 is connected to the rack 5 for transmission. The first drive motor 6 is used to drive the drive gear 7.

[0033] Please see Figure 1 A second drive motor 10 is provided on one side of the upper end of the L-shaped side frame 9.

[0036] This solution: The material plate is placed inside the storage cavity 3. The first drive motor 6 controls the rotation of the drive gear 7, which engages with the rack 5, thus converting the rotational motion of the drive gear 7 into the linear motion of the side sliding shell 8. This causes the self-cleaning adsorption mechanism at the lower end of the slider 12 to move back and forth. The second drive motor 10 controls the rotation of the drive screw 11. With the screw engagement between the slider 12 and the drive screw 11, and the sliding connection between the slider 12 and the L-shaped side frame 9, the rotational motion of the drive screw 11 is converted into the left and right linear motion of the slider 12. This causes the self-cleaning adsorption mechanism at the lower end of the slider 12 to move left and right, thereby adsorbing the workpiece and placing it inside the round box 30. The electric push rod 31 is activated to clamp the workpiece through the clamping block 32. The fourth drive motor 28 is activated to rotate the connecting rod 29, thereby flipping the workpiece to the right end. The electric telescopic rod 14 of the self-cleaning adsorption mechanism at the front end of the rotating rod 27, in conjunction with the suction cup 16, adsorbs the workpiece. The fifth drive motor 33 causes the workpiece to flip backward and be sent to the milling area. After milling, the suction cup 16 approaches the workpiece, closes the first solenoid valve 19, and opens the second solenoid valve 20 and the high-speed fan 22. The high-speed fan 22 generates a high-speed airflow that is guided to the suction cup 16 through the air pipe 18 and the three-way shell 15 and sprayed out, thereby cleaning the surface of the workpiece. Then, the second solenoid valve 20 is closed and the high-speed fan 22 is opened, and the first solenoid valve 19 and the vacuum generator 21 are opened, and the workpiece is adsorbed by the suction cup 16. When the self-cleaning adsorption mechanism at one end of the rotating rod 27 is unloading, the self-cleaning adsorption mechanism at the other end of the rotating rod 27 can perform the loading work. The workpiece is placed in the round box 30 and flipped to the right end by the self-cleaning adsorption mechanism at the lower end of the slider 12 in advance. Then, the self-cleaning adsorption mechanism at the other end is used to adsorb the workpiece for later use. The third drive motor 26 is used to make the rotating rod 27 rotate to replace the workpiece.
