Abstract

The utility model discloses a glue supplying device which includes a pedestal and a glue base. The pedestal includes a rotatable glue disk and a spreading device, wherein, the glue disk is disposed on the pedestal, and the spreading device is disposed above the glue disk; the pedestal comprises a motor, an output wheel and a rotary wheel, wherein the output wheel connected with the output end of the motor drives the rotary wheel to rotate, and a slot is set on the pedestal and adapt to the bottom of the glue base which can be embodied on or detached from the slot, so that the pedestal and the glue base can be assembled or detached. In the combining status, the glue disk can be driven to rotate by contacting and connecting the rotary wheel of the pedestal with the glue disk of the glue base. The rotary wheel of the utility model drive the glue disk by friction, in this manner, the assembly and the detaching of the glue base and the pedestal can be easily achieved. The glue base can be taken out at any moment, and can be easily washed, assembled and freezing stored, i.e. the glue base can be operated alone. Further, one pedestal can be used corresponding to multiple glue bases, thereby reducing the device cost and the storage space, so that the device can be easily and flexibly operated.

Description

A kind of glue feeder

Technical field

The utility model relates to a kind of electronic device processing unit (plant), and a kind of fixing glue feeder with viscose glue that is used to provide is provided.

Background technology

In the electronics process, as the making processing of LED, need carry out a glue fixed operation usually, promptly at first chip or crystal grain are fixed on the LED cup, give carrying out follow-up bonding wire operation again after a glue is fixed by a glue operation then.In addition, in actual applications, also have and put glue earlier and then carry out solid brilliant bonding wire.

Used this glue can be conducting resinl, is also referred to as " elargol ", be conducting metal (as silver of trickle sheet etc.) is mixed with sticker, and the colloid with conduction state that forms after evenly being in harmonious proportion.Usually, this glue is very expensive, and in the time need not after must preserve at low temperatures, otherwise can go bad, and to put the glue consumption very few at every turn, so when some glue operation,, be the problem that people particularly pay close attention to for the quality of glue particularly key.In addition, also having and use other viscose glue, can be that to conduct electricity also can be nonconducting.

The present glue feeder that adopts, normally drive and scrape lacquer disk(-sc) and rotate by the mode of motor by belt pulley, so that motor and scrape the binding that is necessary for hardware between the lacquer disk(-sc), this mode can cause the difficulty in the assembling naturally, and rubber base can not dismantle separation easily, brought inconvenience for freezing preservation.In addition, lacquer disk(-sc) lid protection area is less, the problem that sizing material overflows occurs through regular meeting, and is not easy to observe and adjust for the thickness of glue.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can dismantle the separation rubber base easily, is convenient to the freezing preservation of sizing material, and configuration and glue feeder flexible and convenient to use.

The purpose of this utility model is achieved by the following technical programs:

A kind of glue feeder that the utility model provides comprises support and rubber base, and described rubber base comprises base, rotating lacquer disk(-sc) and frictioning mechanism, and wherein lacquer disk(-sc) is arranged on the base, and frictioning mechanism is arranged on the top of lacquer disk(-sc); Described support comprises motor, output wheel and runner, and wherein output wheel is connected the output of motor, and drives the runner rotation, and support is provided with the corresponding adaptive seat groove of base with rubber base; The base of described rubber base can embed and separate this groove, makes can to make up mutually and separate between rubber base and the support, and the contact of the runner of assembled state lower support and the lacquer disk(-sc) of rubber base is connected and drives the lacquer disk(-sc) rotation.The utility model drives lacquer disk(-sc) by motor by output wheel and runner and rotates, and the sizing material on the lacquer disk(-sc) is obtained to have the sizing material of uniform thickness by the strickling of frictioning mechanism, carry out follow-up some glue operation then.Runner and lacquer disk(-sc) are by friction transmission power, and its connected mode is convenient to realize the combination of rubber base and support and separate.Rubber base can take out at any time, is convenient to clean, the freezing preservation of assembling or sizing material, and can with the rubber base separately operative goals promptly.In addition, a support can use by corresponding a plurality of rubber bases, has reduced the cost and the storage area of device, flexible and convenient operation.

For ease of frictional drive, runner described in the utility model can be made by rubber or plastic material.It is skewed that the contact-making surface of described output wheel and runner can be, promptly with non-perpendicular, appropriateness is oblique be good, with raising transmission effect.

Also be provided with the runner governor motion on the support described in the utility model, comprise wheel frame, elastic component and threaded adjusting bar, runner is via its rotating shaft location at two ends up and down, and the rotating shaft of top is fixed in the wheel frame of rectangular turnover, and wheel frame and runner are done as a whole can moving in the groove of support; The wheel frame links the threaded adjusting bar by elastic component, and this adjusting lever is arranged on the screw of machine wall.Rotation threaded adjusting bar can be regulated the position of runner, and then adjusts the friction of runner.

Be fixing rubber base better, the seat groove of support described in the utility model is made of antetheca, rear wall and support bottom surface, and its antetheca is provided with tapped through hole, and this through hole is provided with tommy; Its lateral surface of the base of described rubber base is provided with the groove corresponding with swing arm.The screw-in of tommy can prop up the groove in base of rubber base, and rubber base can be stable on the support.Its right-hand end of seat groove of support described in the utility model is provided with stop part, can locate rubber base better.

The top seat of honour that also is provided with of its lacquer disk(-sc) of rubber base described in the utility model, described frictioning mechanism comprises tool rest, scraper, scraper fixed block, slide bar, spring and screw rod, wherein tool rest is arranged on the seat of honour, slide bar vertically is fixed in the tool rest, one end of scraper fixed block is located on the slide bar with guide hole, and scraper then is fixed on the other end of scraper fixed block; Spring-loaded is in tool rest between scraper fixed block and the seat of honour; A threaded adjustment hole is opened at the top of tool rest, screw rod pass this threaded adjustment hole and be against the scraper fixed block above.The screw rod rotation then moves up and down, and in conjunction with the effect of spring, the scraper fixed block is moved up and down along slide bar, and then drives scraper lifting thereupon, thereby adjusts the distance between scraper and the lacquer disk(-sc), and the thickness of sizing material is provided for a glue as required.

The seat of honour described in the utility model part covers lacquer disk(-sc), covers area at least 60%.Sizing material is difficult for overflowing the lacquer disk(-sc) surface like this, is convenient to observe operation simultaneously.

For preventing overflowing of sizing material in the frictioning process, the nearly outer rim place of rubber base described in the utility model is provided with Pan Gou.

The utlity model has following beneficial effect:
