DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] The present application discloses a feeding device for a circuit board placement machine, such as Figure 1 and Figure 2As shown, it includes a frame 1 arranged on a circuit board placement machine, two support shafts 2 for supporting the tape roll, a plurality of partition plates 3 and a plurality of top covers 4. An opening is arranged at the upper end of the frame 1, and the tape roll is placed in the frame 1 through the opening of the frame 1. The partition plates 3 are arranged in the frame 1 in a horizontal direction, and a gap for placing the tape roll is left between two adjacent partition plates 3. By placing the tape roll between two partition plates 3, the partition plates 3 can be effectively limited to reduce the occurrence of entanglement. The partition plate 3 is provided with a tray opening 35, which is in an arc shape, so that it is convenient for manual use to take the used tape roll out of the frame 1 through the tray opening 35.

[0034] Both ends of the support shaft 2 are fixedly connected to the inner wall of the frame 1, and the two support shafts 2 are connected to the partition plate 3. The two support shafts 2 are arranged perpendicular to the partition plate 3. Two rotating parts 21 are arranged between two adjacent partition plates 3. The two rotating parts 21 are respectively sleeved on the two support shafts 2. The rotating parts 21 and the support shafts 2 are rotatably connected. After the belt roll is placed in the frame 1, the belt roll is downwardly abutted against the two rotating parts 21 under the action of gravity. During the rotation of the belt roll, the rotating part 21 rotates synchronously with the belt roll, which effectively reduces the friction between the belt roll and the support shaft 2.

[0035] like Figure 2 and Figure 3 As shown, a notch 31 is provided on one side adjacent to the partition plate 3, and an extrusion block 33 for extruding both sides of the tape roll is provided in the notch 31. The extrusion block 33 is slidably provided in the notch 31 along a length direction parallel to the support shaft 2, and a spring 32 is provided on the side of the extrusion block 33 away from the tape roll. The extrusion block 33 is pushed outward by the spring 32 to extrude part of the extrusion block 33 out of the notch 31. The part of the extrusion block 33 extending out of the notch 31 is tapered. When the tape roll enters between the partition plates 3 along the upper end opening of the frame 1, the tape roll moves downward. The extrusion block 33 is abutted against the extrusion block 33, and the extrusion block 33 is retracted into the groove 31 under the force. The extrusion block 33 is divided into a sliding part 331 and a rotating part 332 rotatably connected to the sliding part 331. The rotating part 332 abuts against the tape, and the sliding part 331 is fixedly connected to the spring 32. When the tape rotates, the rotation axis of the rotating part 332 coincides with the rotation axis of the tape. The spring 32 drives the sliding part 331 to move so that the rotating part 332 squeezes the rotation axis position of the tape to ensure the stability of the tape during rotation.

[0036] like Figure 2As shown, the top cover 4 is arranged between two adjacent partition plates 3, and is used to seal the upper end opening between the two adjacent partition plates 3. The top cover 4 is provided with a discharge port 41 connected to the inner cavity of the frame 1. The carrier tape in the tape is extended through the discharge port 41 and connected to the patch gun. A guide wheel 44 rotatably connected to the discharge port 41 is arranged on the upper side of the discharge port 41. The two ends of the guide wheel 44 are rotatably connected to the side wall of the discharge port. The rotation axis of the guide wheel 44 is parallel to the support shaft 2. The carrier tape in the tape abuts against the guide wheel 44, reducing the friction between the carrier tape and the top cover 4, and playing a protective role for the carrier tape. One side of the top cover 4 is rotatably connected to the upper end surface of the frame 1. The frame 1 is provided with a first torsion spring 42 for driving the top cover 4 away from the frame 1. The two ends of the first torsion spring 42 are respectively fixedly connected to the frame 1 and the top cover 4. There is at least a gap between the top cover 4 and the frame 1 for the tape to be placed inside the frame 1.

[0037] like Figure 2 and Figure 4 As shown, the frame 1 is provided with a limiting assembly 5 for enabling the top cover 4 to overcome the force of the first torsion spring 42 and abut against the frame 1 . The limiting assembly 5 includes a connecting portion 51, a limiting portion 52 rotatably connected to the outer end surface of the frame 1 and a second torsion spring 53 for driving the limiting portion 52 to reset. The connecting portion 51 is arranged on a side of the top cover 4 away from the first torsion spring 42. The connecting portion 51 is provided with a barb 511, and the barb 511 is located on both sides of the discharge port 41. The rotation axis of the limiting portion 52 is parallel to the rotation axis of the top cover 4. A notch is provided at the upper end of the limiting portion 52 to match the barb 511. The barb 511 abuts against the notch under the action of the first torsion spring 42. By pressing the lower end of the limiting portion 52, the limiting portion 52 rotates to make the notch away from the barb 511, and the first torsion spring 42 drives the top cover 4 to rotate upward. The two ends of the second torsion spring 53 are respectively fixedly connected to the frame 1 and the limiting portion 52. When the top cover 4 is manually rotated downward, the second torsion spring 53 drives the upper end of the limiting portion 52 to approach the connecting portion 51, so that a stable connection is formed between the barb 511 and the notch.

[0038] The implementation principle of this embodiment is:

[0039] First, move the limiting part 52 to make the notch of the limiting part 52 and the hook 511 of the connecting part 51 move away from each other. The top cover 4 rotates upward under the action of the first torsion spring 42, and the belt roll is placed between two adjacent partition plates 3. The belt roll is downwardly abutted against the two rotating parts 21. The two extrusion blocks 33 squeeze the belt roll under the action of the spring 32, and the carrier tape in the belt roll is passed out along the discharge port 41. Then the top cover 4 is closed, and the second torsion spring 53 drives the limiting part 52 to abut against the connecting part 51 to fix the top cover 4.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
