[0002] During the processing of saw blades used for cutting, the sides and front and rear corners of the saw blade need to be ground. When grinding the saw blade, it is necessary to transfer the saw blade between different grinding stations.

Rotary arm robots are mostly driven by synchronous belts, which have large backlash and are not easy to adjust. Moreover, this robot is not equipped with X-axis movement. Utility Model Content

[0022] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of at least two components or the interaction relationship of at least two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. The embodiments of this invention are further described in detail below with reference to the accompanying drawings:
[0023] Please see Figure 1-5 This utility model provides an embodiment including a double-sided grinding station 2 for a saw blade, a front angle grinding station 3, a rear angle grinding station 4, a cantilever flipping mechanism 5 for transferring the saw blade, and a multi-directional linkage transfer mechanism 1. During the cutting process, the saw blade needs to be ground on both sides and at its front and rear angles. When switching from grinding the sides to grinding the front and rear angles, the saw blade needs to be changed from a vertical position to a horizontal position. The cantilever flipping mechanism 5 for transferring the saw blade is located between the double-sided grinding station 2 and the front angle grinding station 3. It flips the saw blade, which has been ground vertically on both sides, to a horizontal position on one side of the front angle grinding station 3, facilitating grinding at the front angle. At this time, the multi-directional linkage transfer mechanism 1 transfers the horizontally positioned saw blade from the cantilever flipping mechanism 5 to the grinding position on the front angle grinding station 3. Simultaneously, it also facilitates convenient transfer between the grinding positions on the front angle grinding station 3 and the rear angle grinding station 4.
[0024] Specifically, the multi-directional linkage transfer mechanism 1 includes a base plate 10. A slide table 15 is slidably mounted on the upper surface of the base plate 10 via two guide rails 13. A rack 14 is installed between the two guide rails 13. A horizontal servo motor 28 is fixedly mounted on the upper surface of the slide table 15. The output end of the horizontal servo motor 28 meshes with the rack 14 via a gear, so that when the horizontal servo motor 28 is driven to rotate, the slide table 15 moves horizontally along the guide rails 13, thereby achieving horizontal adjustment. A rotational adjustment mechanism is also installed on the upper surface of the slide table 15. A mounting plate 18 is detachably mounted on the rotating end of the rotating assembly. An adsorption fixing plate 22 is mounted on the bottom of the mounting plate 18 via a lifting assembly. The adsorption end of plate 22 uses an electromagnet 24 to grip the saw blade and uses lifting to pick up and put down the saw blade. The center of the electromagnet 24 is through, making the electromagnet 24 ring-shaped. The adsorption fixing plate 22 has a through groove corresponding to the through hole of the electromagnet 24. A positioning post 23 is slidably connected in the groove. The bottom end of the positioning post 23 is directly opposite the center position of the electromagnet 24. A return spring is connected between the top end cap of the positioning post 23 and the upper end face of the adsorption fixing plate 22. An extension 26 is fixedly installed on the front end face of the adsorption fixing plate 22. A buffer slide post 27 is slidably connected through the extension 26. A buffer ring 25 is fixedly installed at the bottom of the buffer slide post 27. A compression spring is connected between the top end cap of the buffer slide post 27 and the extension 26.
[0025] When the electromagnet 24 is used to attract and grip the saw blade, the saw blade will first come into contact with the buffer ring 25 for cushioning, preventing the saw blade from impacting the electromagnet 24 due to the attraction force, which would cause wear on the saw blade. After cushioning, the center hole of the saw blade passes through the bottom end of the positioning post 23 to form a position. By adjusting the horizontal position and the rotation of the rotating component, the saw blade is transferred to the position to be ground on the front angle grinding station 3 or the rear angle grinding station 4. Then, the lifting component is driven to lower the saw blade to the corresponding position to be ground. At this time, the bottom of the positioning post 23 will abut against the round shaft of the position to be ground, thus pushing the positioning post 23 upward, allowing the center hole of the saw blade to fall into the round shaft position of the position to be ground. The power output of the electromagnet 24 is then disconnected, releasing the saw blade.
[0026] It should be noted that, in this embodiment, the rotating assembly includes a servo rotary table 16 fixedly installed on the upper surface of the slide table 15, and a buffer slide column 27 is fixedly connected to the rotation output end of the servo rotary table 16. The mounting plate 18 is detachably installed on the upper surface of the rotating column 17.
[0027] It is worth mentioning that, in this embodiment, the lifting assembly includes a lifting cylinder 19 fixedly installed on the upper surface of the mounting plate 18. The telescopic end of the lifting cylinder 19 is fixedly connected to the adsorption fixing plate 22. Guide cylinders 21 are respectively installed on both sides of the upper surface of the mounting plate 18 and the lifting cylinder 19. A guide post 20 is slidably passed through each guide cylinder 21. The bottom of both guide posts 20 is fixedly connected to the upper surface of the adsorption fixing plate 22. The guide posts 20 on both sides cooperate with the guide cylinders 21 to make the vertical lifting more stable.
[0028] In another embodiment, a dustproof baffle 11 is fixedly connected to the upper surface of the base plate 10, and a telescopic dustproof cover 12 is installed on the dustproof baffle 11. The telescopic dustproof cover 12 covers the guide rail 13, and the telescopic dustproof cover 12 is used to prevent the debris from saw blade grinding from affecting the sliding adjustment of the guide rail.
[0029] In specific implementation, when the cantilever tilting mechanism 5 tilts the saw blade that has been polished at the double-sided grinding station 2 to a horizontal position, firstly, the horizontal servo motor 28 is controlled to rotate to drive the slide table 15 to move to one side of the saw blade position. The electromagnet 24 is aligned with the center position of the saw blade to be grasped. The lifting cylinder 19 is activated to drive the adsorption fixing plate 22 to move downward, so that the electromagnet 24 adsorbs and grasps the saw blade. After the saw blade is adsorbed, the horizontal servo motor 28 is controlled to adjust the position of the slide table 15. At the same time, the servo rotating table 16 is activated to rotate and move the saw blade to the corresponding corner position to be polished. At the same time, the lifting cylinder 19 drives the adsorption fixing plate 22 to move downward and place the saw blade in the corresponding corner position to be polished. The material handling of the saw blade is controlled by a three-axis PLC numerical control system, which can realize the setting of the working position at any point in a limited space, and has great flexibility.
[0030] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
