Therefore, they should not be construed as limitations on the utility model.

[0019] In this embodiment, as Figure 2 , Figure 6 As shown, insert 1 is ring-shaped, and the top surface of insert 1 is annular surface 2; Figure 1 , Figure 2As shown, an insert 1 feeding mechanism includes: a directional conveying component, an insert receiving and lifting component, and a clamping component. The directional conveying component is used to output the insert 1 in a preset posture along a straight line. In this embodiment, the preset posture is: the axial direction of the insert 1 is vertical, and the annular surface 2 of the insert 1 is on top; the directional conveying component outputs the insert 1 along a first direction. The receiving module includes a receiving plate 3 adjacent to the feeding port of the directional conveying component, and a first driving component that drives the receiving plate 3 to reciprocate along a second direction perpendicular to the first direction. In this embodiment, the first driving component is a first cylinder 5. Figure 1 As shown, the first direction is the X-axis, and the second direction is the Y-axis. Figure 2 As shown, the directional conveying assembly includes a vibratory feeder 6, and a linear guide is provided at the outlet of the vibratory feeder 6. The linear guide includes a linear U-shaped groove 7 arranged along a first direction in the length direction, and a cover plate 8 covering the linear U-shaped groove 7. The bottom of the linear U-shaped groove 7 is flush with the bottom of the receiving groove 4 in the horizontal direction. In this embodiment, the vibratory feeder 6 continuously vibrates to feed the material, and the insert 1 is output in a preset posture along a straight line through the vibratory feeder 6, which is simple and efficient in structure.

[0020] like Figure 4 , Figure 5 As shown, the insert receiving and lifting assembly includes a receiving module, a lifting module, and a detection component. The receiving module is used to receive insert 1 from the outlet of the directional conveying assembly and drive insert 1 to move along a preset direction, while blocking the output of subsequent inserts 1 from the directional conveying assembly. The lifting module is used to lift the moved insert 1 vertically. The detection component is used to detect whether insert 1 has completely entered the predetermined position of the receiving module.

[0021] like Figure 4 , Figure 5As shown, the receiving plate 3 has a receiving groove 4 for accommodating the insert 1 at the outlet of the directional conveying component; the insert receiving and lifting component includes a side stop 9 fixedly installed on the side of the directional conveying component; when the receiving plate 3 moves away from the outlet of the conveying component along the second direction, the side stop 9 blocks the groove of the receiving groove 4 that is biased towards the directional conveying component, preventing the insert 1 from dislodging from the receiving groove 4 when the receiving plate 3 moves, and at the same time, it cooperates with the receiving groove 4 to position the insert 1 in the receiving groove 4 so that the top rod 10 can accurately lift the insert 1 in the receiving groove 4. The receiving plate 3 is provided with a through hole that penetrates the bottom of the receiving groove 4 and corresponds to the movement trajectory of the top rod 10 so that the top rod 10 can complete the lifting action. In this embodiment, the receiving plate 3 is configured to move along the Y-axis, which allows the receiving plate 3 to receive the insert 1 conveyed from the directional conveying component and simultaneously block the output of subsequent inserts 1 from the directional conveying component. If the receiving plate 3 is not configured to move along the Y-axis, since the vibratory feeder 6 continuously vibrates to supply material, a blocking mechanism is required at the outlet of the directional conveying component to prevent subsequent inserts 1 from moving forward, thus avoiding interference caused by the lifting of inserts 1 in the receiving trough 4, which would make the structure more complex.

[0022] like Figure 4 , Figure 5 As shown, the lifting module includes a lifting rod 10 and a second driving component that drives the lifting rod 10 to rise and fall. The second driving component is fixed to the bottom end surface of the receiving plate 3. In this embodiment, the second driving component is a second cylinder 14; Figure 6 As shown, the push rod 10 is multi-segmented with varying diameters, including a conical portion 11, a first cylindrical portion 12, and a second cylindrical portion 13 from top to bottom. The cross-sectional area of ​​the conical portion 11 gradually changes from small to large at the bottom. The maximum diameter of the conical portion 11 is equal to the diameter of the inner ring of the annular surface 2. The diameter of the first cylindrical portion 12 is equal to the diameter of the inner ring of the annular surface 2. The diameter of the second cylindrical portion 13 is larger than the diameter of the inner ring of the annular surface 2. In this embodiment, when the push rod 10 lifts the insert 1 in the receiving groove 4, the insert 1 is fitted onto the first cylindrical portion 12. The conical portion 11 and the first cylindrical portion 12 are used to precisely position the insert 1, which facilitates the subsequent clamping of the clamping assembly.

[0023] The detection component is a through-beam sensor 18 (e.g.) Figure 4 As shown, the receiving plate 3 has a detection channel along a direction parallel to the second direction, located on the side of the receiving groove 4 away from the directional conveying assembly, for allowing the optical signal of the through-beam sensor 18 to pass through. The detection channel is a through groove, and the through groove is connected to the receiving groove 4. In this embodiment, when the insert 1 is fully inserted into the receiving groove 4, the optical path of the through-beam sensor 18 is blocked, thereby driving the first cylinder 5 to move the receiving plate 3 along the second direction away from the discharge port of the conveying assembly.

[0024] like Figure 3As shown, the gripping assembly is used to grip the lifted insert 1 on the lifting module and transfer it to the next workstation. The gripping assembly includes a robot arm 15 and multiple gripping units with identical structures located at the end of the robot arm 15. Each gripping unit includes a gripper cylinder 16 and a pair of gripping members 17 fixed on the gripper of the gripper cylinder 16. There are two gripping units. The free ends of the pair of gripping members 17 are horizontally inverted V-shaped notches arranged opposite each other. In this embodiment, the V-shaped notches form a geometric constraint with the outer circle of the insert 1 through line contact, which can automatically correct the radial position deviation of the insert 1 and ensure concentricity during gripping.

[0025] The working principle of the insert 1 feeding mechanism in this utility model is as follows: In the initial state, the piston rod of the first cylinder 5 retracts, the receiving groove 4 of the receiving plate 3 is directly opposite the discharge port of the directional conveying component, the piston cylinder of the second cylinder 14 retracts, and the push rod 10 is at the lowest point of its lifting stroke. Upon starting the operation, the vibratory feeder 6 begins continuous feeding, and the linear guide outputs an insert 1. When the through-beam sensor 18 detects that the insert 1 has completely entered the receiving groove 4, the first cylinder 5 drives the receiving plate 3 to move along the Y-axis away from the discharge port of the conveying component (i.e., towards...). Figure 4 (Using the orientation as a reference, the receiving plate 3 moves to the left). At the same time, the receiving plate 3 blocks the subsequent insert 1 in the linear guide from moving forward. After the receiving plate 3 stops moving, the second cylinder 14 drives the push rod 10 to rise, lifting the insert 1 from the receiving groove 4. One gripping unit of the robot arm 15 grips the insert 1 on the push rod 10. Then the piston rod of the second cylinder 14 retracts, driving the push rod 10 to fall. At the same time as the push rod 10 falls, the piston rod of the first cylinder 5 retracts, driving the receiving plate 3 to reset, so that the receiving groove 4 is directly opposite the outlet of the directional conveying component. Repeat the previous steps to receive the second insert 1 and lift it. Another gripping unit of the robot arm 15 grips the second insert 1 on the push rod 10. Then the robot arm 15 places the two inserts 1 in the predetermined position, and repeats the feeding process.
