Description

Technical Field

[0001] The utility model relates to the technical field of feeder feeding equipment, in particular to a feeder stripping mechanism. Background Art

[0002] Feida is the transliteration of Feeder, which is generally translated as feeder or feeder. Its function is to install SMD chip components on the feeder, and the feeder provides components to the placement machine for placement.

[0003] The working principle of the current feeder feeder is as follows: the material tape is fixed to the feeder unwinding shaft of the placement machine. The upper tape and the SMD components are separated by a separation plate. The upper tape is then wound onto the take-up reel. The SMD components are picked up by the SMD machine's retrieving device for placement processing. The rotation of the take-up reel winds the upper tape, thus separating the material tape and the SMD components on the separation plate.

[0004] When the feeder is peeling off the chip devices on the material tape, the material tape is bent at the front edge of the separation plate, thereby tearing the chip devices off on the upper tape. However, in the above method, when the material tape is bent and conveyed along the front edge of the separation plate, the chip devices are easily bent and conveyed along with the upper tape, resulting in poor tearing effect of the chip devices, affecting the feeding efficiency of the feeder.

[0037] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0038] like Figure 1-5 As shown, an embodiment of the utility model provides a flyer stripping mechanism, in which a stripping plate 200 is slidably set on the vertical plate 100, and is driven to slide in a straight line by a stripping drive device 220, while driving the pulling rod 210 to move, so that the material belt 001 wound on the stripping plate 200 can be moved on the stripping plate 200, so that the patch device can be torn off on the upper belt by slow movement.

[0039] Specific examples Figure 1-5 As shown, the embodiment of the present invention provides a feeder stripping mechanism, which includes a vertical plate 100, a stripping plate 200, a pulling rod 210, a stripping drive device 220 and a pulling roller group 230, wherein the vertical plate 100 includes two mutually opposed stripping plates 200; the two ends of the stripping plate 200 are respectively slidably connected to the vertical plate 100 along the length direction of the vertical plate 100; the pulling rod 210 is specially provided on the lower surface of the stripping plate 200, and a stripping roller 220 is provided between the pulling rod 210 and the lower surface of the stripping plate 200. A spacing space; the stripping drive device 220 is fixedly installed on any one of the vertical plates 100 and is in transmission connection with the stripping plate 200 to drive the stripping plate 200 to move back and forth in a straight line; the traction roller group 230 is arranged on the lower side of the stripping plate 200, which includes an active roller 231 and a driven roller 232 opposed to each other up and down, and a traction motor 233 fixedly installed on any one of the vertical plates 100, the traction motor 233 is in transmission connection with the active roller 231, and drives the active roller 231 to rotate around the axis.

[0040] In the process of tearing off the SMD components on tape 001, Figure 6 This is a schematic diagram of the structure of the stripping mechanism provided by the embodiment of the utility model installed on the feeder. Figure 7 A schematic diagram of the stripping mechanism provided for the material strip 001 to pass around an embodiment of the present invention, wherein the material strip 001 is pre-wound on the unwinding shaft 310, and the end of the material strip 001 passes around the tensioning wheel 320 and the pressing mechanism 330, passes around the upper surface of the stripping plate 200, and is bent toward the rear along the front edge of the stripping plate 200 before passing around the pulling rod 210. It can be imagined that by setting the position and angle between the pressing mechanism 330 and the stripping plate 200, the material strip 001 located on the stripping plate 200 can be tightly attached to the stripping plate 200, wrapped along the circumferential surface of the pulling rod 210 and extended to the direction of the traction roller group 230, passed between the active roller 231 and the driven roller 232, and then wrapped around the receiving shaft 340.

[0041] During the tearing operation, one end of the material strip 001 is pressed by the pressing mechanism 330, and the other end is fixed by the receiving shaft 340. The stripping drive device 220 drives the stripping plate 200 to move in a straight line on the vertical plate 100. At this time, since the material strip 001 bypasses the pulling rod 210, the material strip 001 located on the upper surface of the stripping plate 200 is pulled by the pulling rod 210. 1 moves toward the front side relative to the upper surface of the stripping plate 200. At this time, when the material strip 001 flips and moves along the front end surface of the stripping plate 200, the SMD components on the material strip 001 are torn off. It can be imagined that by driving the stripping plate 200 to move along a straight line, the movement stroke is small, and the material strip 001 is in a tight and fixed state, so that the SMD components on the material strip 001 can be accurately torn off, thereby ensuring the efficiency of the feeder feeding.

[0042] In this embodiment, since the material strip 001 passes around the pull rod 210, in order for the material strip 001 to move along the circumferential surface of the pull rod 210, the stripping plate 200 is further provided with two mutually opposed mounting seats 211. The mounting seats 211 are fixedly mounted on the underside surface of the stripping plate 200, and the ends of the pull rod 210 are rotatably connected to the mounting seats 211. By rotatably mounting the pull rod 210 on the riser 100, the material strip 001 can be smoothly moved along the circumferential surface of the pull rod 210.

[0043] In this embodiment, in order to adapt to the conveying of the material strip 001 with different thicknesses, Figure 2 As shown, two vertical plates 100 are each provided with a chute 101 in the vertical direction. The traction roller assembly 230 also includes a bearing seat 234 and an adjustment cylinder 235. Two bearing seats 234 are provided, each slidably connected within the chute 101. The driven roller 232 is rotatably connected to the bearing seats 234 at both ends. Two adjustment cylinders 235 are provided, corresponding to the two bearing seats 234, and are respectively connected to the bearing seats 234 for driving the bearing seats 234 to reciprocate in a straight line. By adjusting the cylinders 235, the gap between the active roller 231 and the driven roller 232 can be changed, thereby accommodating the conveyance of material strips 001 of varying thicknesses.

[0044] In this embodiment, to accurately and stably drive the stripping plate 200, the stripping drive device 220 includes a drive motor 221, a synchronous pulley 222, a synchronous belt 223, and a connecting block 224. Specifically, the drive motor 221 is fixedly mounted on the riser 100; the synchronous pulley 222 is rotatably connected to the riser 100 and is located in a section where the stripping plate 200 is disposed; the synchronous belt 223 is transmission-connected between the drive motor 221 and the synchronous pulley 222, allowing the drive motor 221 to drive the synchronous belt 223 to rotate; and the connecting block 224 has one end fixedly mounted on the synchronous belt 223 and the other end fixedly connected to the stripping plate 200. The drive motor 221 drives the stripping plate 200 to move via the synchronous belt 223 and the synchronous pulley 222, thereby providing stable and accurate drive for the stripping plate 200 and improving the reliability of the stripping process.

[0045] In this embodiment, the stripping plate 200 includes a plate body 201, a light source plate 203 and an upper side plate 204204. Specifically, the two ends of the plate body 201 are respectively slidably connected to the vertical plate 100, and a mounting groove 202 is provided on the upper surface of the plate body 201; the light source plate 203 is arranged in the mounting groove 202 and is electrically connected to an external power supply to provide a light source; it is stacked on the light source plate 203, and a stripping portion 205 extending out of the range of the light source plate 203 is provided at its front end. In this embodiment, the upper side plate 204 is made of a translucent material, which can ensure that the light source of the light source plate 203 can pass through the upper side plate 204 to illuminate the material strip 001 and the patch device.

[0046] During the stripping process, the light source plate 203 and the upper side plate 204 are provided, so that the lower side of the material strip 001 can be illuminated to the material strip 001 and the SMD device. The above-mentioned structural design can facilitate the SMD machine to provide a light source for the material picking mechanism of the SMD machine during the process of grabbing the SMD device, so that the material picking mechanism can position the SMD device and accurately grab the SMD device. At the same time, a stripping portion 205 is provided at the front end of the upper side plate 204, and the stripping portion 205 extends out of the periphery of the light source plate 203. At this time, Figure 7 As shown, in the process of bending and moving the material strip 001 along the stripping portion 205 of the upper side plate 204, since the thickness of the stripping portion 205 is smaller than the overall thickness of the stripping plate 200, the bending radius of the material strip 001 at the stripping portion 205 is smaller, thereby improving the stripping effect of the material strip 001.

[0047] In this embodiment, in order to further improve the stripping effect, the front end surface of the stripping portion 205 is provided with a guide surface 206 inclined in the direction of the pull rod 210, and a stripping blade 207 is defined between the guide surface 206 and the upper surface of the stripping portion 205. It can be imagined that the stripping portion 205 is provided with a guide surface 206, so that the material strip 001 can be bent along the guide surface 206. In the process of moving along the surface of the guide surface 206, the material strip 001 is bent along the stripping blade 207, further reducing the bending radius of the material strip 001. At the same time, in the process of bending and moving along the blade 207, the material strip 001 will be scraped by the blade 207, so that the surface mount components can be separated from the material strip 001, thereby improving the stripping effect.
