Description

Technical Field

[0001] The utility model relates to the technical field of feeder feeding equipment, in particular to a feeder pressing 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 feeding, the Feida feeder usually feeds intermittently, that is, the receiving wheel rotates intermittently, and the upper belt and the patch device are also separated intermittently, so that it can adapt to the picking component on the placement machine to complete accurate feeding and picking.

[0005] However, during the rotation of the take-up wheel, the material tape will generate a momentary large pulling force on the unwinding shaft used by the feeder to roll the material tape, causing the unwinding shaft to rotate, thereby pulling the material tape out of the material tape roll. The unwinding shaft and the material tape roll continue to rotate under the action of inertia, causing the length of the material tape between the unwinding shaft and the separation plate to be too long, resulting in loose material tape. Due to the excessive length and looseness of the material tape, the separation of the upper tape and the SMD device is affected, which will cause the feeder feeding accuracy and efficiency to decrease.

DETAILED DESCRIPTION

[0027] 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.

[0028] like Figure 2-4 As shown, the embodiment of the present invention provides a feeder pressing mechanism 200, which is used to be installed on the feeder feeder. When the feeding is stopped, the material strip is clamped in advance to prevent the part of the material strip located on the separation plate 320 from being in a loose state, ensuring that the material strip is continuously tightened, so that the upper tape and the patch device can be separated more accurately, ensuring the feeding accuracy. Figure 1The structural state diagram of the material pressing mechanism 200 installed on the feeder feeder is as follows: the material tape is wound on the unwinding shaft 310, and the material tape passes through the material pressing mechanism 200 and the separation plate 320 in sequence and is then wound on the take-up wheel 330. During the rotation of the take-up wheel 330, the material tape can be pulled to move along the separation plate 320, thereby separating the upper tape and the patch device from each other at the edge of the separation plate 320. During this process, the material pressing mechanism 200 clamps the material tape to prevent the material tape from loosening and affecting the separation of the patch device and the upper tape.

[0029] like Figure 2-4 As shown, an embodiment of the present invention provides a feeder pressing mechanism 200, which includes a vertically arranged frame 100, on which are arranged: a first guide rod 110, a base plate 120 and a clamping assembly 130. Specifically, one end of the first guide rod 110 is arranged on the frame 100, and the other end extends toward the outside; the base plate 120 is arranged on the downstream side of the first guide rod 110 along the feeder conveying direction, and the base plate 120 is arranged in an inclined state relative to the horizontal plane; the clamping assembly 130 is arranged above the base plate 120, and includes a clamping plate 131 and a clamping drive device 132, wherein the clamping plate 131 and the base plate 120 are arranged parallel to each other, and the clamping drive device 132 is transmission-connected to the clamping plate 131, driving the clamping plate 131 to move back and forth toward or away from the base plate 120.

[0030] The first guide rod 110 is provided with a first pressing member 131 and a second pressing member 132 is provided with a first pressing member 133 which is provided with a first pressing member 134. The first guide rod 110 is provided with a first pressing member 134 which is provided with a first pressing member 134 and a second pressing member 135.

[0031] In this embodiment, to facilitate installation of the compression assembly 130, a crossbeam 133 is fixedly mounted on the frame 100. The crossbeam 133 is disposed above the base plate 120, and the compression drive device 132 is fixedly mounted on the crossbeam 133. In other words, the compression assembly 130 can be suspended above the base plate 120 via the crossbeam 133, thereby facilitating compression of the material strip.

[0032] In this embodiment, to increase the tension of the material strip during compression, the end of the bottom plate 120 adjacent to the first guide rod 110 is located at the upper side, the end of the bottom plate 120 distal from the first guide rod 110 is located at the lower side, and the height of the upper end of the bottom plate 120 is located below the height of the lower side of the circumferential surface of the first guide rod 110. It is conceivable that when the material strip is pressed against the bottom plate 120 by the compression plate 131, the material strip bends along the inclination of the bottom plate 120, thereby increasing the tension of the material strip.

[0033] In this embodiment, in order to allow the material strip to be smoothly conveyed along the first guide rod 110 , the first guide rod 110 includes a rod 111 fixedly mounted on the frame 100 , and also includes a roller 112 rotatably connected to the rod 111 .

[0034] To prevent the strip from slipping while being conveyed along the first guide rod 110, at least two fixed rings 113 are fixedly mounted on the roller 112, spaced evenly apart. As the strip passes through the first guide rod 110, it is conveyed by the at least two fixed rollers. The smaller contact area with the fixed rings 113 reduces friction between the strip and the first guide rod 110, and also mitigates the impact of roller pressure on the SMD components.

[0035] In order to increase the pressure of the material belt when it passes through the bottom plate 120, a number of air ducts are arranged inside the bottom plate 120. At least one exhaust hole 121 connected to the air duct is opened on one end surface of the bottom plate 120. The exhaust hole 121 is used to be connected to an external exhaust device through a pipeline. A number of suction holes 122 connected to the air duct are opened on the end surface of the bottom plate 120 corresponding to the clamping plate 131.

[0036] By providing the upper surface of the bottom plate 120 with suction holes 122 , the material strip can be adsorbed by negative pressure when passing through the bottom plate 120 , thereby increasing the resistance to the material strip and further ensuring the tension of the material strip.

[0037] In this embodiment, a second guide rod 140 is further disposed on the frame 100, located downstream of the base plate 120 along the flyer conveying direction. More specifically, an extension arm 141 is disposed on the end of the base plate 120 away from the frame 100. One end of the extension arm 141 is fixedly mounted on the base plate 120, and the other end extends horizontally away from the base plate 120. The ends of the second guide rod 140 are respectively mounted on the extension arm 141 and the frame 100. During the conveying process, the material strip passes through the first guide rod 110, then the base plate 120, and then around the bottom side of the second guide rod 140. This allows the material strip to be held in close contact with the base plate 120 under the second guide rod 140. It is worth noting that if the clamping assembly 130 malfunctions, the material strip, guided by the second guide rod 140, can remain in close contact with the base plate 120. The suction force of the suction holes 122 can thus ensure that the material strip is kept in close contact with the base plate 120. It can be understood that the second guide rod is installed with the base plate through an extension arm, that is, the second guide rod and the end of the base plate away from the first guide rod are located on the same horizontal plane. At this time, the material strip can be in contact with the base plate as a whole under the guidance of the second guide rod, ensuring the adsorption effect of the base plate on the material strip.

Although the present invention is disclosed as above in terms of preferred embodiments, they are not intended to limit the present invention. Any technician familiar with the profession can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical content disclosed above.
