Background technology
Chip mounter, claim placement equipment, " surface mount system " (Surface Mount System) again, in production line, chip mounter is a kind of special equipment that surface mount elements mounts, utilize the walking of control system control mounting head, finish chip pickup by the mounting head suction nozzle from feeder, and automatically with chip attachment on the corresponding pad locations of specified circuit plate, finally realize mounting automatically of circuit chip on board.The loader of general large-scale chip mounter is mainly independently to fly reaching (feeder) structure, flies independently that Danone is finished the accurate feeding of strip, feed, useless nylon tape such as peel off at function automatically.But often based on the integrated form loader, this structure makes useless nylon tape peel off with removal process and can not independently finish, and can not well realize peeling off and reclaiming in the limited small table formula chip mounter of volume and cost.
The utility model content
In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of nylon automatic stripper of chip mounter strip, can come nylon tape on the rolling strip according to a constant material stripping moment, in chip mounter, have good realizability and applicability.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of nylon automatic stripper of chip mounter strip comprises drive unit, power transmission shaft and is arranged at some rolling wheels on the described power transmission shaft that described drive unit and power transmission shaft are connected.
As preferably, described drive unit comprises drive motors and synchronizing wheel, and drive motors one end is connected by belt with synchronizing wheel.
As preferably, described rolling wheel comprises bearing, bearing stator, rubber ring and the clamping stator that arranges with one heart successively, and bearing is arranged in the bearing stator, and the bearing stator other end is fixed on by rubber ring and clamps stator one side.
As preferably, described rubber ring arranges friction plate up and down respectively, and described friction plate is radially vertical with rubber ring.
As preferably, described clamping stator is provided with the vertical U-shaped groove at the center of passing, and clamps stator outer lateral edges two ends V-type groove breach is set respectively, is provided with two pressure jackscrews in the described U-shaped groove.
The beneficial effects of the utility model are, simple in structure, process easy to assembly, cost of manufacture is low and autgmentability is strong, independently material stripping structure has been simplified the design of integrated form feeder greatly, adopts one to drive many designs, and making only needs a drive source that the material stripping moment of all nylon rolling wheel can be provided, greatly reduce the production cost of material stripping drive source, improved production efficiency.

Embodiment:
Be easy to understand understanding in order to make creation characteristic of the present utility model, technological means and to reach purpose, further set forth the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1~Fig. 2, a kind of nylon automatic stripper of chip mounter strip comprises drive unit, power transmission shaft 4 and is arranged at some rolling wheels 5 on the described power transmission shaft 4 that described drive unit and power transmission shaft 4 are connected.Drive unit comprises drive motors 1 and synchronizing wheel 2, and drive motors 1 one ends are connected by belt 3 with synchronizing wheel 2.Rolling wheel 5 comprises bearing 7, bearing stator 8, rubber ring 9 and the clamping stator 11 that arranges with one heart successively, and bearing 7 is arranged in the bearing stator 8, and bearing stator 8 other ends are fixed on by rubber ring 9 and clamp stator 11 1 sides.Rubber ring 9 arranges friction plate 10 up and down respectively, and friction plate 10 is radially vertical with rubber ring 9.Described clamping stator 11 is provided with the vertical U-shaped groove 12 at the center of passing, and clamps the breach that stator 11 outer lateral edges two ends arrange V-type groove 13 respectively, is provided with two pressure jackscrews 14 in the described U-shaped groove 12.
Bearing 7 is in order to support whole rolling wheel 5 and to guarantee the upright position of rolling wheel 5 relative power transmission shafts 4.Clamp stator 11 in order to carry damping structure, damping rubber circle 9 in its inner chamber and friction plate 10, damping rubber circle 9 is held tightly on power transmission shaft 4 and by two friction plates 10 and is compressed, and produces a damping frictional force therebetween, and drives whole rolling wheel 5 rotations by this frictional force.Each friction plate 10 vertically is pressed on the damping rubber circle 9 by a pressure jackscrew 14, thereby the dynamic friction that the degree of depth of regulating this pressure jackscrew can be controlled between friction plate 10 and the rubber ring 9 is regulated the material stripping moment that rolling wheel 5 strips nylon tape 6.
Material stripping moment to strip in the chip mounter has requirement, if moment too the young pathbreaker cause material stripping failure to make can't successfully taking out materials and parts; Get the material precision if will tear the position influence of strip too greatly.The utility model is by increasing pressure jackscrew parts, and the damping force of regulating the pressure jackscrew is regulated the size of moment, and these parts have very strong adaptability, can adjust the strip of different dynamics.The V-type groove makes things convenient for nylon tape to be fixed on the rolling wheel at first in order to block the nylon tape tieing.
The material stripping moment of all rolling wheels attached to it is provided by power transmission shaft during work, is one and drives many structures with one.Each rolling wheel provides a fixing pulling force to nylon tape separately, and because rolling wheel is that string is on power transmission shaft, so independently be independent of each other mutually between each rolling wheel.
The strip of chip mounter will provide suitable dynamics that nylon tape is separated strip and recovery by retracting device after entering feeder.When drive motors turns round, the mechanical energy that drive motors produces sends synchronizing wheel to by belt, and then the power transmission shaft rotation that is connected of drive and synchronizing wheel, drive motors and power transmission shaft provide its enough big moment make rolling wheel rotate and drive nylon rolling wheel attached on it, the nylon rolling wheel will come nylon tape on the rolling strip according to a constant material stripping moment, so, nylon tape namely is recovered and spools on rolling wheel.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
