Qie Xi send tin integrated chip machine feeding equipment
Technical field
The utility model relates to and is applied to electron surface and mounts (that is: SMT mounts)/welding technology field, more particularly, is to relate to a kind of tin of cutting to send tin integrated chip machine feeding equipment, and it is mainly chip mounter or other mount/the welding equipment supply shape tin grain that looses.
Background technology
In the SMT industry, the components and parts on a lot of PCB (printed circuit board) for guaranteeing welding quality, need add the tin grain at weld when welding; The tin grain is placed into the position that needs through chip mounter or other mounting devices; Yet the way in the current industry is to buy the tin grain of import, therefore, has been packaged into the strip form during supplied materials, and this strip can directly use ready-made chip mounter feeder (being called for short " flying to reach " in the industry) to be supplied to chip mounter to mount; Yet there is following weak point in it: (1) makes cheap originally tin grain unit price become very expensive in view of its packing is complicated; (2) there is not Qie Xi to send tin integrated chip machine feeding equipment yet, therefore, both can't have used tin insulating material on the market, restricted production efficiency again to a certain extent; (3) certain limitation is installed, can only achieves a butt joint, can not satisfy other and mount/the welding equipment requirement with corresponding chip mounter.
The utility model content
The purpose of the utility model is to overcome all deficiencies that exist in the above-mentioned prior art, and provides a kind of simple and reasonable for structure, can select for use the tin volume as raw material; Sending tin/cut tin to cooperate synchronously accomplishes; Transmitting range is short, speed is fast, efficient is high, the tin particle size, send tin speed to adjust arbitrarily, and tin grain positioning accuracy is high; Can obviously reduce use cost, and the Qie Xi that does not produce the packaging material waste material send tin integrated chip machine feeding equipment.
The purpose of the utility model is achieved in that

Qie Xi send tin integrated chip machine feeding equipment; Comprise main mounting panel and control electronic box; It is characterized in that; Be respectively arranged with volume tinware, solder drive, guide pipe, cut tinware, tin grain gathering sill and tin grain alignment sensor by forward and backward order on the said main mounting panel, the solder drive is connected with the drive motor, and guide pipe is crossed on the solder drive and cuts between the tinware; Cut between tinware and the tin grain alignment sensor and be provided with tin grain gathering sill, the control electronic box respectively with the drive motor, cut tinware and tin grain alignment sensor and electrically connect; This kind of is cut tin and send tin integrated chip machine feeding equipment, and tin is reeled on the volume tinware, and the solder delivery wheel directly rolls solder flat to setting thickness and being sent in the middle guide pipe; Solder is sent to guide pipe and extends to cuts tinware, cuts tinware solder is cut into the tin grain of preseting length, and tin grain first place joins and gets into the gathering sill of tin grain; When if tin grain alignment sensor is sensed the tin grain; Show that the tin grain arrives position to be inhaled, tin grain alignment sensor feedback signal is to control system, and everything stops to wait for the chip mounter suction; After treating that chip mounter siphons away a tin; Tin grain alignment sensor loses induction, then the solder drive with cut the tinware startup that cooperatively interacts, next tin grain is sent to tin grain alignment sensor sensed position.So circulation can realize repeating to mount.
The purpose of the utility model can also adopt following technical measures to solve:
As scheme more specifically, the said tinware of cutting comprises Qie Xi mechanism and cuts the tin drive motors, and Qie Xi mechanism drives and advises by cutting the tin motor, realizing the cutting tin function, and cuts the tin drive motors and electrically connects with the control electronic box, to realize automatic control.
Be the convenient tin grain that receives, also be provided with on the main mounting panel of the discharging opening below of said tin grain gathering sill and connect the tin box that tin grain alignment sensor is positioned at the said top that connects the tin box.
Also be provided with forward and backward feeder detent mechanism on the said main mounting panel.
As better scheme, said forward and backward feeder detent mechanism is arranged on the bottom of main mounting panel.
The feeder detent mechanism is positioned at the below of guide pipe before said, and back feeder detent mechanism then is arranged on the below of tin grain alignment sensor.

Said solder drive comprises wheel and lower whorl, leaves solder between upper and lower the wheel and rolls flat gap, and last wheel is installed in the output shaft of drive motor, and lower whorl is a free state, and the said tube chamber inlet that rolls flat gap alignment guide pipe; Upper and lower take turns with solder directly roll flat to set thickness and be sent in the middle of guide pipe in, solder is sent to guide pipe and extends to cuts tinware, cuts the tin grain that tinware is cut into solder preseting length again.
Said volume tinware comprises rolling wheel, spool and rolling wheel frame thereof, and the rolling wheel frame is installed on the main mounting panel, and rolling wheel is arranged on the spool and through spool and is installed on the rolling wheel frame, and it is on the rolling wheel that solder is reeled.
Said main mounting panel is provided with the polylith supporting bracket, and guide pipe is arranged on the polylith supporting bracket.
The beneficial effect of the utility model is following:
(1) Qie Xi of the utility model send tin integrated chip machine feeding equipment, and tin is reeled on the volume tinware, and the solder delivery wheel directly rolls solder flat to setting thickness and being sent in the middle guide pipe; Solder is sent to guide pipe and extends to cuts tinware, cuts tinware solder is cut into the tin grain of preseting length, and tin grain first place joins and gets into the gathering sill of tin grain; When if tin grain alignment sensor is sensed the tin grain; Show that the tin grain arrives position to be inhaled, tin grain alignment sensor feedback signal is to control system, and everything stops to wait for the chip mounter suction; After treating that chip mounter siphons away a tin; Tin grain alignment sensor loses induction, then the solder drive with cut the tinware startup that cooperatively interacts, next tin grain is sent to tin grain alignment sensor sensed position; So circulation can realize repeating to mount, and it is simple and reasonable for structure, can select for use the tin volume as raw material, and in view of it can carry independent control electronic box, convenient and any chip mounter is installed and docked;
(2) have again, accomplish owing to send tin/cut tin to cooperate synchronously, transmitting range is short, speed is fast, efficient is high, the tin particle size, send tin speed to adjust arbitrarily, and tin grain positioning accuracy is high, can obviously reduce use cost, and does not produce advantage such as packaging material waste material.
