The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Some embodiments of the present application are described in detail. In the following embodiments, features of the embodiments may be combined with each other without conflict.

Referring to fig. 1 and fig. 2, a feeding device 1 provided in this embodiment includes a frame 11, a material belt 12, a film 13, and a separating assembly 14. One side surface of the material tape 12 is recessed along the thickness direction thereof to form a groove 121. The film 13 is applied to the strip of material 12 to cooperate with the recesses 121 to form a cavity 122, the cavity 122 being used to receive the part 15 to be assembled. A separating assembly 14 is mounted to the frame 11, the separating assembly 14 being adapted to separate the strip 12 from the film 13 along the length of the strip 12 to fully expose the parts 15 to be assembled.

The parts 15 to be assembled may be relatively small sized parts 15, such as foam, snaps or other sheet-like resilient parts 15. The size of the component 15 is within 20mm (length) × 20mm (width) × 5mm (thickness), for example, foam with a thickness of 5mm or 1mm, a snap with a thickness of 0.8mm, a metal spring with a thickness of 0.2mm, etc.

The recess 121 is shaped to follow the shape of the element 15, for example a rectangular recess 121 for securing the element 15 within the recess 121.

The feeding device 1 fixes the position of the part 15 to be assembled with the material belt 12 by placing the part 15 to be assembled in the cavity 122 of the material belt 12, so that the ordered arrangement of the part 15 can be realized, and then the material belt 12 is separated from the film 13 by the separating component 14, so that the part 15 is completely exposed out of the groove 121 for taking and assembling the part 15, and the feeding and assembling position precision of the part 15 is improved.

Referring to fig. 3, in the present embodiment, there are a plurality of grooves 121, and the grooves 121 are arranged at intervals along the length direction of the material tape 12. The plurality of grooves 121 are used to feed the parts 15 in batches while being arranged in order.

The width of the film 13 may be greater than or equal to the size of the opening of the recess 121, so that the film 13 covers the opening of the recess 121 completely to form a sealed chamber 122, which facilitates long-term storage of the parts 15 in the strip of material 12.

The width of the film 13 may also be smaller than the opening size of the groove 121 so that the film 13 does not completely close the groove 121. The tape 12 and the groove 121 form a semi-closed chamber 122, so that the atmospheric pressure inside and outside the chamber 122 is the same, which facilitates the separation of the film 13 from the tape 12 by reducing the pressure difference inside and outside the chamber 122, and facilitates the separation of the film 13 from the tape 12, so as to reduce the influence on the position accuracy of the part 15 in the tape 12 when the film 13 is separated.

Referring to fig. 4, the frame 11 includes a guide post 118, a material tray 111, a rotating shaft 112, and an adjusting block 113. The roll tray 111 is used for winding the supply tape 12.

The adjusting block 113 is movably connected with the rotating shaft 112, and the adjusting block 113 can adjust the pressure of the winding tray 111 on the material tape 12 along the axial direction of the rotating shaft 112. The guide posts 118 are used to maintain the strip of material 12 in a tangential direction with respect to the take-up reel 111 when the strip of material 12 is being rotated out of the take-up reel 111. Two guide posts 118 may be used, one on each side of the strip of material 12, to maintain the direction of movement of the strip of material 12.

Referring to fig. 5, in the present embodiment, the adjusting block 113 includes a main shaft 114, a pressing block 115, and an elastic member 116. The main shaft 114 passes through the rotating shaft 112, and one end of the main shaft 114 abuts against one side of the coil tray 111. The pressing block 115 is provided at the other end of the main shaft 114 and presses the other side of the coil tray 111 in the axial direction of the main shaft 114. The elastic member 116 is inserted through the main shaft 114, and the elastic member 116 is disposed between the pressing block 115 and the material winding tray 111 to adjust the pressing force. The elastic force can be calculated according to the elastic deformation of the elastic member 116, so as to control the pressure of the pressing block 115 on the coil tray 111. The pressure of the pressing block 115 on the material winding tray 111 is adjusted to be beneficial to keeping the material strip 12 in a roll shape when the material strip 12 is wound in the material winding tray 111, so that the material strip 12 is prevented from being changed into a messy and scattered strip in the moving process, and the position of the part 15 in the material strip 12 is kept.

The adjusting block 113 further comprises a concentric ring 117, the rotating shaft 112 is sleeved with the concentric ring 117, and the concentric ring 117 and the pressing block 115 are arranged on the same side of the coil tray 111, so that the direction of the pressing force is axially aligned with the main shaft 114. The concentric rings 117 are used to fix the shaft 112 firmly, so that the shaft 112 and the spindle 114 are kept on the same axis, and the material belt 12 is prevented from driving the material winding disc 111 to shake during rotation. The concentric rings 117 further stabilize the take-up reel 111 to maintain the position of the parts 15 in the strip of material 12.

The resilient member 116 controls the amount of compression force, the concentric rings 117 control the direction of the compression force, and the resilient member 116 and the concentric rings 117 maintain the strip of material 12 in a roll at a certain compression force.

The film 13 is torn from the strip of material 12 by the discrete pieces 149, the film 13 is blocked by the discrete pieces 149 and moves away from the structural frame 119, and the strip of material 12 passes between the discrete pieces 149 and the structural frame 119 and continues to move along the structural frame 119. When the film 13 is torn from the tape 12, the separating block 149 presses the tape 12 to prevent the tape 12 from being pulled by the film 13, thereby reducing the positional deviation of the component 15 in the groove 121.

The tape strip adjuster 124 is connected to the frame 119, and after the tape 12 passes through the separation block 149, the tape 12 continues to move along the frame 119 and passes through the tape strip adjuster 124.

The tape press plate 125 is connected to the tape frame 119, and after the tape 12 passes through the tape control plate 124, the tape 12 continues to move along the tape frame 119 and passes through the tape press plate 125. The tape press 125 is aligned with the separator block 149 and the tape adjuster plate 124, and the tape press 125 is used to maintain the linear movement of the tape 12.

The strip receiving plate 126 is connected to the frame 119, and after the strip 12 passes through the strip pressing plate 125, the strip 12 continues to move along the frame 119 and passes through the strip receiving plate 126.
