Figure 1 The diagram illustrates a preferred embodiment of an automatic bushing feeding device for automatically gripping supports from the support feeding area 1 and bushings from the bushing feeding area 2 into the pressing area 3 for pressing. The device includes a feeding robot 4, a first gripping mechanism 5, and a second gripping mechanism 6. The feeding robot 4 has a mounting frame 41 at its execution end. The support feeding area 1, bushing feeding area 2, and pressing area 3 are distributed circumferentially along the feeding robot 4. Both the first gripping mechanism 5 and the second gripping mechanism 6 are mounted on the mounting frame 41. When the feeding robot… When robot 4 moves the first gripping mechanism 5 to the bushing feeding area 2, the first gripping mechanism 5 grips the bushing located in the bushing feeding area 2. When the feeding robot 4 moves the second gripping mechanism 6 to the bracket feeding area 1, the second gripping mechanism 6 grips the bracket located in the bracket feeding area 1. When the feeding robot 4 moves the first gripping mechanism 5 and the second gripping mechanism 6 to the pressing area 3, the second gripping mechanism 6 places the gripped bracket in the pressing area 3, and the first gripping mechanism 5 places the gripped bushing at the corresponding assembly hole of the bracket.

[0023] In actual production, the loading robot 4 moves circumferentially through the mobile mounting frame 41, passing through the bracket loading area 1, the bushing loading area 2, and the pressing area 3 in sequence. When passing through the bracket loading area 1, the second gripper drive grips the bracket in the bracket loading area 1. When passing through the bushing loading area 2, the first gripper mechanism 5 grips the bushing in the bushing loading area 2. The second gripper mechanism 6 passes through the pressing area 3 first and places the bracket in the pressing area 3. Then the first gripper mechanism 5 passes through the pressing area 3 again and makes a part of the bottom of the bushing coaxially inserted into the assembly hole on the bracket. Finally, the bushing is pressed into the bracket by the pressing equipment 9 in the pressing area 3.

[0024] In this application, the automatic gripping and placement of brackets and bushings is realized by the feeding robot 4 and the first and second gripping mechanisms 6 installed on the mounting frame 41 at its execution end. The bracket feeding area 1, bushing feeding area 2 and pressing area 3 are distributed around the feeding robot 4, making the entire feeding process more compact and smooth, improving production efficiency, reducing manual operation, reducing labor costs, and increasing production cycle time.

[0025] Furthermore, as a preferred embodiment, the first gripping mechanism 5 includes: a first pneumatic two-finger gripper 51, one of which has a first clamping block 52, and the other gripper has two first clamping blocks 52, with the three first clamping blocks 52 arranged in a triangular pattern. The first pneumatic two-finger gripper 51, with its three triangularly arranged first clamping blocks 52, can grip the bushing from multiple directions, increasing the stability and accuracy of the gripping and effectively preventing the bushing from slipping or shifting during gripping and movement.

[0026] Furthermore, in a preferred embodiment, one of the first clamping blocks 52 is located on the vertical line between the other two first clamping blocks 52. When the first gripping mechanism 5 moves to the bushing feeding area 2, the two jaws of the first pneumatic two-finger gripper 51 are located on both sides of the bushing. By the mutual approach of the two jaws, the three first clamping blocks 52 are clamped on the outer circumferential surface of the bushing respectively.

[0027] Furthermore, as a preferred embodiment, each first clamping block 52 has an arc-shaped clamping groove 521, which matches the curvature of the outer circumferential surface of the bushing. The matching of the arc-shaped clamping groove 521 with the curvature of the outer circumferential surface of the bushing allows for better contact with the bushing surface, increasing the clamping area, improving clamping stability and reliability, reducing damage to the bushing during the gripping process, and ensuring product quality.

[0028] Furthermore, as a preferred embodiment, each arc-shaped clamping groove 521 has friction patterns 522 on its inner arc surface. The friction patterns 522 on the inner arc surface of the arc-shaped clamping groove 521 can further increase the friction between the clamping block and the bushing, preventing the bushing from slipping due to vibration or external force during gripping and movement, thereby improving the working stability and reliability of the gripping mechanism.

[0029] Furthermore, as a preferred embodiment, the second gripping mechanism 6 includes a second pneumatic two-finger gripper 61, the two grippers of the second pneumatic two-finger gripper 61 respectively gripping the two sides of the bracket.

[0030] Furthermore, as a preferred embodiment, two second clamping blocks 62 are provided on the opposite end faces of the two jaws of the second pneumatic two-finger gripper 61, and the two second clamping blocks 62 respectively clamp the two sides of the bracket side. Providing two second clamping blocks 62 on the opposite end faces of the two jaws of the second pneumatic two-finger gripper 61 further increases the clamping points on the bracket, improves the stability and accuracy of clamping, and can better adapt to brackets of different sizes and shapes, enhancing the versatility of the gripping mechanism.

[0031] Furthermore, as a preferred embodiment, the bushing feeding area 2 is located between the support feeding area 1 and the pressing area 3. This layout makes the path of the feeding robot 4 more reasonable during movement, reduces unnecessary movement distance, improves feeding efficiency, and also contributes to the compactness and continuity of the entire production process, further improving the production cycle time.

[0032] Furthermore, as a preferred embodiment, the first gripping mechanism 5 and the second gripping mechanism 6 are on the same horizontal plane and form an angle. When the first gripping mechanism 5 moves to the bushing feeding area 2, the second gripping mechanism 6 is located between the bushing feeding area 2 and the pressing area 3.

[0033] Furthermore, as a preferred embodiment, robot 4 is a six-axis robot 4. The six-axis robot 4 has six degrees of freedom, enabling flexible and precise movement in three-dimensional space. It can better adapt to the gripping and placement operations of supports and bushings at different positions and angles, improving the flexibility and versatility of the entire automatic feeding device, and further enhancing production efficiency and product quality.

[0034] Based on the above, this utility model also has the following embodiments: The bushing feeding area 2 is equipped with a vibratory plate 8 for automatically feeding the bushings. The width of the discharge end of the vibratory plate 8 matches the diameter of the bushing, and the height matches the axial length of the bushing.

[0035] More preferably, the discharge end of the vibratory feeder 8 extends outward to a discharge plate 81, and the discharge plate 81 has baffles on both sides. When the bushing is placed in the vibratory feeder 8, the vibration of the vibratory feeder 8 causes the bushing to move one by one from the discharge end to the discharge plate 81. Then the first gripping mechanism 5 grips the bushing located on the discharge plate 81. The purpose of setting the baffles is to limit the two sides of the bottom of the bushing to prevent the bushing from tipping over.

[0036] More specifically, the first gripping mechanism 5 first grips the bushing located at the first end of the discharge plate 81. In order to keep the gripping position unchanged each time, a limiting plate (not shown in the figure) can be set at the first end of the discharge plate 81. On the one hand, this prevents the bushing from falling off the first end of the discharge plate 81. On the other hand, it ensures that the gripping position of the first gripping mechanism 5 remains unchanged each time.

[0037] The bracket placement area has a support frame 7 for array placement of several brackets. More specifically, several hanging rods 71 ​​are arrayed on the support frame 7, and several brackets are respectively hung on several hanging rods 71. These brackets are hung manually.

[0038] The pressing area 3 has a pressing device 9 (existing equipment) for pressing the bushing downward into the mounting hole of the bracket.

[0039] Even better, in order to improve the gripping and placement accuracy of the first gripping mechanism 5 and the second gripping mechanism 6, a vision inspection module can be set on the mounting frame 41. The vision inspection module is connected to the first gripping mechanism 5, the second gripping mechanism 6 and the robot 4 by signal, and is used to detect the position of the bracket and bushing. The vision inspection module can be a 3D camera.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
