Description

Technical Field

[0001] The invention relates to the field of tape braiding machine devices, and in particular to a feeding mechanism and a tape braiding machine. Background Art

[0002] The fully automatic taping machine is used to place bulk component products into carrier tape after passing through inspection, reversing, testing and other stations. With the continuous upgrading, refinement and high integration of electronic products, electronic components have also been transformed from plug-in type to surface mount type to save installation space of circuit boards and expand product functions.

[0003] The manufacturing process of MLCC generally includes: selecting ceramic dielectric powder to make slurry - casting ceramic dielectric film - internal electrode printing - multi-layer stacking - lamination - cutting - high temperature sintering - ball milling - dip-capped electrode - end sintering and surface treatment - test taping. Taping is to weave the tested MLCC into a carrier tape and roll it into a plastic reel according to a fixed number. Taping is to facilitate the large-scale high-speed automatic mounting production in the SMT process, and it can also prevent problems such as collision and cracking of MLCC caused by transportation and other processes.

[0004] In order to facilitate the grabbing and use of chip capacitors, the chip capacitors on the rubber disc need to be placed in the same direction, that is, the stacking direction of the chip capacitors is consistent and upward during taping. Existing MLCC taping machines usually use a vibration plate for automatic loading. Although the vibration plate can automatically arrange disordered workpieces in an orderly manner through vibration, it cannot ensure that the stacking direction of the chip capacitors is consistent and upward.

[0005] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

[0006] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a feeding mechanism and a tape braiding machine.

[0007] The present invention can be implemented by the following technical solutions: The present invention discloses a feeding mechanism, comprising a frame, a vibrating table is fixed on the frame, a vibrating plate is fixed on the vibrating table, a screw rod and a sliding rod are arranged on the frame above the vibrating plate, the screw rod is driven to rotate by a feeding motor, a slide is also arranged above the vibrating plate, the screw rod passes through the slide and is threadedly connected to the slide, the sliding rod passes through the slide and is slidably connected to the slide, a suction plate is arranged below the slide, a lifting cylinder is also fixed on the slide, the piston rod end of the lifting cylinder is fixed to the suction plate, a plurality of electromagnets are also evenly fixed in the suction plate, a conveying belt is arranged on the frame on one side of the vibrating plate, the conveying belt is driven to rotate by a conveying motor, a feeding belt is also arranged on the frame on one side of the feeding belt, the feeding belt is driven to rotate by a feeding motor, and baffles are fixed on the frames on both sides of the feeding belt. The chip capacitor has a flat structure. When the chip capacitor is placed on a flat plate, it is either facing up with its front side facing up or with its back side facing up, which is opposite to the front side. The inner electrode of the chip capacitor is generally made of metal material. Since the chip capacitor has magnetic inner electrodes stacked inside, the capacitor is poured into the vibration plate, and the vibration plate is driven to vibrate by the vibration table. The capacitor is laid flat on the vibration plate and moves toward the bottom of the suction plate. After the capacitor is laid flat on the vibration plate under the suction plate, the lifting cylinder is started, the piston rod on the lifting cylinder is extended, and the suction plate descends. After the suction plate contacts the capacitor on the vibration plate, the electromagnets in the suction plate are energized. After the electromagnets are energized, magnetism is generated, and the capacitor with the correct direction is attracted to the suction plate. After the capacitor with the front side facing up is attracted to the suction plate, the lifting cylinder is started, and the piston on the lifting cylinder is extended. The rod is shortened, the suction plate rises, the capacitor is adsorbed on the suction plate and rises with the suction plate, the feeding motor drives the screw rod to rotate, and the slide moves in the direction of the screw rod when the screw rod rotates. After the slide reaches the top of the conveyor belt, the feeding motor stops, the lifting cylinder starts again, the piston rod on the lifting cylinder extends, the suction plate descends, and after the suction plate reaches the conveyor belt, the electromagnet is powered off, the magnetism of the electromagnet disappears, the lifting cylinder starts again, the suction plate is separated from the capacitor, and the conveying motor drives the conveyor belt to rotate, the capacitor moves with the conveyor belt, the capacitor moves toward the feeding conveyor belt, the capacitor reaches the feeding conveyor belt and is blocked by the baffle, and the capacitor is transported forward on the feeding conveyor belt as the feeding conveyor belt rotates. This device can form a row of capacitors for forward transportation after the orientation is correctly placed, which is convenient for the use of the subsequent taping machine.

[0008] Preferably, a fence is fixed on the vibration plate.

[0009] Preferably, guide rods are symmetrically fixed to the frames on both sides above the conveyor belt.

[0010] Preferably, a limit plate is fixed on the frame above the feeding conveyor belt and the conveying conveyor belt. By setting the limit plate, the capacitor can be prevented from turning over when it reaches the feeding conveyor belt from the conveying conveyor belt, ensuring the correct direction.

[0011] Preferably, the vibration plate is also provided with a positioning groove, a push plate is provided in the positioning groove, a plurality of positioning rods are fixed on the push plate, the positioning rods pass through the vibration plate below the positioning groove and are slidably connected with the vibration plate, the bottoms of the positioning rods are fixed on the positioning plate, a plurality of springs are fixed between the positioning plate and the vibration plate, a plurality of lifting cylinders are fixed on the frame below the positioning plate, and the piston rod ends of the lifting cylinders are fixed to the lifting plate. After the capacitors that are not attracted and grabbed reach the push plate position, the lifting cylinder is started, the piston rod on the lifting cylinder is extended, the lifting plate rises, and the lifting plate pushes the positioning plate to move after contacting with the positioning plate, and the push plate rises with the positioning plate, and pushes the capacitor to flip after contacting with the capacitor. After flipping, the capacitor is grabbed by the suction plate again, and the ones with the correct direction are sucked for loading, and the rest stay on the vibration plate again, and are pushed by the push plate for multiple times until the direction is correct and then they are sucked for loading.

[0012] A tape braiding machine comprises any one of the feeding mechanisms described above.

[0013] Compared with the prior art, the present invention has the following advantages: The device can place the capacitors in the correct orientation to form a row for forward transportation, making it convenient for the subsequent taping machine to use. BRIEF DESCRIPTION OF THE DRAWINGS

The inner electrode of the chip capacitor is generally made of metal material. Since the chip capacitor has a magnetic inner electrode stacked inside, the capacitor is poured into the vibration disk 3, and the vibration table 2 drives the vibration disk 3 to vibrate. The capacitor is laid flat on the vibration disk 3 and moves under the suction plate 10. After the capacitor is laid flat on the vibration disk 3 under the suction plate 10, the lifting cylinder 9 is started, the piston rod on the lifting cylinder 9 is extended, and the suction plate 10 is lowered.
