It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present utility model and are not used to limit the present utility model.

[0021] As Figures 1 to 3As shown in the figure, an automatic feeding device for a wafer bonding ring according to this embodiment includes a driving rod 1, a sliding seat 2, a clamping device 3, and a slide rail 4. The driving rod 1 is pivotally connected to the sliding seat 2, and the sliding seat 2 is driven to move by the driving rod 1. The sliding seat 2 is arranged on the slide rail 4 and can slide relative to the slide rail 4. The clamping device 3 is arranged on the sliding seat 2 and can thus slide with the sliding seat 2. The clamping device 3 includes a clamping arm 5 and an actuating rod 6. The clamping arm 5 is pivotally connected to the sliding seat 2. The clamping arm 5 has a clamping opening 51. The actuating rod 6 is slidably arranged on the sliding seat 2 and is arranged perpendicular to the slide rail 4. A spring 7 is provided between the actuating rod 6 and the clamping arm 5. One end of the actuating rod 6 is provided with a roller 61, and the roller 61 abuts against a stop bar 8. The stop bar 8 is parallel to the slide rail 4. Thus, when the sliding seat 2 moves, the roller 61 moves on the stop bar 8. The stop bar 8 is provided with a notch 81, and the notch 81 is correspondingly arranged with the roller 61. When the roller 61 enters the notch 81, the clamping opening 51 opens. When the roller 61 disengages from the notch 81, the clamping opening 51 clamps. A placement area 9 is provided on one side of the slide rail 4, and the clamping arm 5 is located in the placement area 9. In the above technical solution, the workpiece 10 is placed in the placement area 9 and at the position of the clamping opening 51; then the driving rod 1 is pushed to make the sliding seat 2 slide inward along the slide rail 4. When the roller 61 is at the position of the notch 81, the driving rod 1 is subjected to the thrust of the spring 7 and drives the roller 61 to move towards the notch. Thus, the clamping opening 51 of the clamping arm 5 is released, enabling the workpiece 10 to reach the specified position for processing. Through the above technical solution, the workpiece can be automatically clamped, released, and displaced in the placement area by the driving rod, thus facilitating the conveyance of the material to the specified position.

[0022] In this embodiment, the clamping arm 5 includes a first clamping component 52 and a second clamping component 53. The first and second clamping components are pivotally connected by a connecting arm 54. The spring 7 presses against the connecting arm 54, enabling the roller 61 to closely abut against the stop bar 8. The first clamping component 52 includes a first clamping arm 521, a first connecting rod 522, and a first mating rod 523. The two ends of the first connecting rod 522 are respectively pivotally connected to the first clamping arm 521 and the first mating rod 523. The second clamping component 53 includes a second clamping arm 531, a second connecting rod 532, and a second mating rod 533. The two ends of the second connecting rod 532 are respectively pivotally connected to the second clamping arm 531 and the second mating rod 533. The first mating rod 523 and the second mating rod 533 are respectively pivotally connected to the connecting arm 54. The first and second clamping arms are pivotally connected to the sliding seat through a fixed arm 55. Through the above technical solution, when the connecting arm 54 moves towards the notch, the first mating rod 523 pulls the first connecting rod 522 to rotate, and the first connecting rod 522 pulls the first clamping arm 521 to rotate and open. Similarly, the second clamping arm can also rotate and open, thus releasing the clamping opening 51.

[0023] In this embodiment, there are two slide rails 4, and the sliding seat 2 is arranged between the two slide rails 4, so that the sliding seat 2 can slide smoothly. The sliding seat 2 includes a main body 21 and a plurality of pulleys 22. The pulleys 22 are arranged on the periphery of the main body 21 and abut against the slide rails 4. By rolling the pulleys 22 on the slide rails 4, the main body 21 can move smoothly. One end of the driving rod 1 is pivotally connected to the main body 21, and the other end is pivotally connected to the protective door 20. Thus, by opening or closing the protective door 20, the driving rod 1 can be driven to move, and then the sliding seat can be driven to move. There are at least two notches 81, and the two notches 81 are arranged at intervals. When in the notch position, the clamping jaws open to release the workpiece. The placement area 9 includes a feeding position 91 and a processing position 92. The two notches 81 correspond to the feeding position and the processing position respectively. Thus, when at the feeding position 91 and the processing position 92, the clamping jaws 51 open, which is convenient for placing and taking the workpiece. Just place the material at the feeding position 91. After closing the protective door, the sliding seat automatically drives the workpiece to slide to the processing position, without the need for workers to place the material at the processing position, and the operation is safer.

[0024] An automatic feeding device for a wafer bonding ring in this embodiment can automatically clamp, release and displace the workpiece in the placement area, so as to facilitate the conveying of the material to the designated position, improve the feeding safety and be convenient to operate.

As long as it does not deviate from the scope of the claims, various deformations or changes can be made. The present invention includes various deformations and changes within the scope of the claims.
