[0002] With the development of technology, the grinding machine currently uses a dedicated automatic feeding device and a robotic arm to feed the material. When feeding, the material is first fed into the grabbing side of the robotic arm through the feeding device, and then the workpiece is grabbed by the equipped robotic arm and placed on the fixed fixture of the grinder to complete a loading operation.

[0003] The Chinese utility model patent application number 202322760326.1 provides a grinding machine feeder. Through the setting of the motor, moving block and clamping plate, the distance between the two sets of clamping plates can be adjusted by the motor and the moving block, so that workpieces of different sizes can be clamped, thereby conveying workpieces of different specifications.

[0004] However, during the use of the above-mentioned equipment, it was found that when the staff placed the workpiece on the conveyor belt, the placement of the workpiece was prone to deviation and tilt, resulting in inaccurate clamping position of the clamping plate during subsequent clamping, making the workpiece difficult to clamp and prone to loosening or even falling during the clamping process.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] See also Figure 1-Figure 4 A grinding machine feeder includes a base 1, a conveyor belt 2 is provided in the middle of the base 1, a feeding box 4 is provided on one end of the base 1, a correction component 3 is provided inside the base 1, and the correction component 3 includes a rotating groove 37. The rotating groove 37 is opened on both sides of the conveyor belt 2, and a rotating rod 32 is rotatably installed in the rotating groove 37. The rotating rod 32 is connected to the output end of the first motor 31, and a worm 33 is provided on both ends of the rotating rod 32. The spiral directions of the worms 33 at both ends of the rotating rod 32 are opposite, and the worm 33 is meshed with the worm gear 34. The worm gear 34 is rotatably set in the rotating groove 37, and a connecting rod 35 is fixedly installed on the top of the worm gear 34. The connecting rod 35 passes through the top of the rotating groove 37 and is rotatably connected to the top of the rotating groove 37. A baffle 36 is fixedly installed on the top of the connecting rod 35, and the baffle 36 is arranged above the top of the conveyor belt 2.

[0025] Specifically, by setting up the correction component 3, the correction component 3 is used to correct the workpiece that is placed tilted, so that it maintains the correct posture when entering the feed box 4. Before the correction, the baffles 36 on both sides of the conveyor belt 2 are set perpendicular to the output direction of the conveyor belt 2. At the same time, the two baffles 36 are closed to form a blockage on the conveyor belt 2. When the workpiece placed on the conveyor belt 2 moves to the baffle 36, it is blocked by the baffle 36, and one end of the tilted workpiece rests on the baffle 36. Due to the continuous movement of the conveyor belt 2, the workpiece is pushed by the conveyor belt 2, causing it to rotate around the end in contact with the baffle 36, so that one side of the workpiece is fitted with the baffle 36 to achieve the correction posture.

[0026] The worms 33 disposed at both ends of the rotating rod 32 have opposite spiral directions, and the worm wheels 34 meshing with the two worms 33 are disposed on the same side of the worms 33 . This allows the two worm wheels 34 to rotate in opposite directions when the worms 33 rotate, thereby controlling the opening and closing of the two baffles 36 .

[0027] After the correction is completed, the first motor 31 is used to drive the rotating rod 32 to rotate, thereby driving the worm 33 at both ends of the rotating rod 32 to rotate, and the engagement of the worm 33 with the worm wheel 34 is used to make the worm 33 drive the worm wheel 34 to rotate, and then the worm wheel 34 controls the connecting rod 35 fixedly connected to its top to rotate, thereby controlling the baffle 36 to rotate, so that the baffle 36 can be turned from a closed state to an open state, so that the corrected workpiece can be moved to the feed box 4 along the conveyor belt 2.

[0028] Example 2:

[0029] To achieve stable clamping of the workpiece and control its movement to the placement table 41, please refer to Figure 1-Figure 4 On the basis of Example 1, a feeding assembly 5 is installed on the top of the feeding box 4, a placement table 41 is provided on one side of the feeding box 4, and the side of the feeding box 4 close to the placement table 41 is connected to the grinding machine;

[0030] The feeding assembly 5 includes a cylinder 51, the output end of the cylinder 51 is connected to a moving block 53, the moving block 53 is slidably arranged on a slide rod 52, and a clamping assembly 6 is installed at the bottom of the moving block 53;

[0031] The slide bar 52 passes through both ends of the moving block 53 and is fixedly mounted on the top of the feeding box 4. The slide bar 52 is perpendicular to the conveying direction of the conveyor belt 2.

[0032] The clamping assembly 6 includes an electric telescopic rod 61, the output end of which is fixedly connected to a clamping frame 62. The clamping frame 62 is arranged parallel to the slide bar 52. A movable groove 67 is formed inside the clamping frame 62. A bidirectional threaded rod 64 is rotatably mounted inside the movable groove 67. The bidirectional threaded rod 64 is connected to the output end of the second motor 63.

[0033] Both ends of the bidirectional threaded rod 64 are spirally connected with a clamping plate 65 , the top of the clamping plate 65 fits in the inside of the moving groove 67 , and the bottom of the clamping plate 65 is fixed with an anti-slip pad 66 .

[0034] Specifically, when the corrected workpiece moves into the feed box 4, the electric telescopic rod 61 in the clamping assembly 6 is extended to control the clamping frame 62 to drive the clamping plate 65 to descend, so that the clamping plate 65 is located on both sides of the workpiece, and the second motor 63 drives the bidirectional threaded rod 64 to rotate. The bidirectional threaded rod 64 is spirally connected to the clamping plate 65, so that the clamping plates 65 at both ends of the bidirectional threaded rod 64 can move toward each other along the moving groove 67, thereby achieving stable clamping of the workpiece. The anti-slip pad 66 on the clamping plate 65 is a rubber layer, which can increase the friction between the workpiece and the clamping plate, so as to prevent the workpiece from falling when the workpiece is moved;

[0035] After the clamping assembly 6 completes clamping, the electric telescopic rod 61 contracts, driving the workpiece to move upward, and the feeding assembly 5 is used to move the workpiece to the placement table 41. When the cylinder 51 in the feeding assembly 5 is working, the moving block 53 is fixedly connected to the piston rod and is restricted on the slide bar 52. The piston rod extends, causing the moving block 53 to move linearly along the direction of the slide bar 52, thereby driving the clamping assembly 6 to control the workpiece to move to the placement table 41. The electric telescopic rod 61 is extended to control the clamping assembly 6 to drive the workpiece to fit the surface of the placement table 41, and the second motor 63 drives the bidirectional threaded rod 64 to rotate in the opposite direction, so that the workpiece can be placed on the placement table 41, which is convenient for the subsequent robotic arm in the grinder to move the workpiece to the fixed table for processing.

[0036] Working principle: When the equipment is in use, the staff places the workpiece on the conveyor belt 2 and uses the conveyor belt 2 to move the workpiece. Under normal conditions, the baffles 36 on both sides of the conveyor belt 2 are in a closed state. Then, when the workpiece moves to the baffle 36, one end of the workpiece is in contact with the baffle 36. Under the continuous movement of the conveyor belt 2, the workpiece is affected by the conveyor belt 2 and rotates around the end in contact with the baffle 36, so that one side of the workpiece is in contact with the baffle 36, achieving posture correction;

[0037] After the correction is completed, the first motor 31 drives the rotating rod 32 to rotate. When the rotating rod 32 rotates, the worm 33 at both ends of the rotating rod 32 drives the worm wheel 34 to rotate, thereby controlling the connecting rod 35 to drive the baffle 36 to open, so that the workpiece can be moved to the inside of the feeding box 4 under the drive of the conveyor belt 2;

[0038] The second motor 63 in the clamping assembly 6 drives the bidirectional threaded rod 64 to rotate, and then controls the clamping plate 65 to move toward each other along the moving groove 67, so that the clamping plate 65 clamps the workpiece. After clamping, the workpiece moves upward under the contraction of the electric telescopic rod 61, and the piston rod in the cylinder 51 is extended to push the moving block 53 to move along the slide rod 52, thereby driving the workpiece to move above the placement table 41. The electric telescopic rod 61 is extended to make the workpiece fit the surface of the placement table 41. The reverse rotation of the second motor 63 is used to enable the clamping assembly 6 to release the clamping of the workpiece, so that the workpiece can be completely placed on the placement table 41, completing the feeding of the workpiece.
