Description
Technical field
The present invention relates to chip mounter technical field, and in particular to a kind of chip mounter with anti-azido functional.
Background technology
Chip mounter is also known as placement equipment or surface mount system, is a kind of equipment being fixed to chip on lead frame.Patch
Piece owner will be made up of framework container, transmission track and mounting head.Lead frame is stacked and is stored in framework container.It is raw
During production, framework container is fallen on transmission track one by one by its internal lead frame, and by transmission track by lead
Framework is sent to the lower section of mounting head, and chip is accurately placed by mobile mounting head the patch sites progress of lead frame
Paster.Chip carrier of the lead frame as integrated circuit is a kind of by means of bonding material (spun gold, aluminium wire, copper wire) realization
The electrical connection of chip internal circuits exit and outer lead, the key structure part of electric loop is formed, it is served and outside
The function served as bridge of wire connection, is required for using lead frame in most semiconductor integrated blocks, is electronics and information industry
In important basic material.With the development trend of miniature semiconductor, existing lead frame is constantly thinning, and its thickness is general
No more than lmm.And the lead frame of this thickness is under framework container when falling on transmission track, it is easy to stick together existing
As, and there is two panels lead frame while situation about dropping on transmission track.When there is two panels lead frame to overlap,
It can make to be bonded between chip and lead frame unstable, and cause product unqualified, and ultimately result in lead frame and chip wave
Take.
The content of the invention
To be solved by this invention is that existing chip mounter lead frame overlapping phenomenon easily occurs, caused by product do not conform to
A kind of the problem of lattice and wastage of material, there is provided chip mounter with anti-azido functional.
To solve the above problems, the present invention is achieved by the following technical solutions：
A kind of chip mounter with anti-azido functional, including framework container, transmission track and mounting head；Transmission track is located at
The front end of framework container, mounting head are located at the rear end of transmission track；It is except that still further comprise anti-stacked framework inspection
Survey mechanism；The anti-stacked framework testing agency includes fixed support, active lever, detection disk roller, sensor, controller and alarm
Composition；Wherein fixed support is fixed on the edge of transmission track；The fulcrum of active lever is connected with fixed support, and to live
Dynamic lever is vertically arranged in the surface of transmission track；The lower end that disk roller is arranged on active lever is detected, and detects the lower end of disk roller
Certain gap is left between face and transmission track, the height in the gap is equal to the thickness of lead frame to be sent；Sensor
With active lever face, the output end of sensor is connected with the input of controller, and the output end of controller is connected with alarm.
When the thickness of the lead frame transmitted on transmission track is more than the gap between the lower surface of detection disk roller and transmission track, inspection
Survey disk roller to be lifted up, active lever rises therewith, and now sensor detects the ascending motion of active lever, sends signal
Alarm is controlled to send alarm to controller, and by controller.
In such scheme, the sensor is photoelectric sensor, the photoelectric sensor include optical transmitting set, optical receiver and
Detect circuit composition；Have one wherein between level height residing for the upper surface of level height residing for optical transmitting set and active lever
Fixed difference in height, the difference in height are less than the thickness of lead frame to be sent；Optical receiver is in same level with optical transmitting set
Highly, the input of circuit and controller connects the output end of the optical receiver after testing.
In such scheme, the halt switch connection of the controller and chip mounter.
In such scheme, the alarm is audible-visual annunciator.
Compared with prior art, the present invention can be examined effectively by installing anti-stacked framework testing agency additional on existing chip mounter
Find two panels and two panels above framework is overlapping is sent to track, equipment downtime is alarmed, reminding employees processing, so directly improve
Welding quality, raw material loss is reduced, so as to reducing production cost.

Embodiment
A kind of chip mounter with anti-azido functional, as shown in figure 1, including framework container 1, transmission track 2 and mounting head
3.Transmission track 2 is located at the front end of framework container 1, and mounting head 3 is located at the rear end of transmission track 2.It is characterized in that：Also enter one
Step includes anti-stacked framework testing agency.The anti-stacked framework testing agency includes fixed support 6-1, active lever 6-2, detection disk roller
6-3, sensor 6-4, controller and alarm composition.Wherein fixed support 6-1 is fixed on the edge of transmission track 2.Activity
Lever 6-2 fulcrum is connected with fixed support 6-1, and causes active lever 6-2 to be vertically arranged in the surface of transmission track 2.Inspection
The lower end that disk roller 6-3 is arranged on active lever 6-2 is surveyed, and detects and is left between disk roller 6-3 lower surface and transmission track 2 necessarily
Gap, the height in the gap is equal to the thickness of lead frame 4 to be sent.Sensor 6-4 and active lever 6-2 faces, are passed
Sensor 6-4 output end is connected with the input of controller, and the output end of controller is connected with alarm.When on transmission track 2
When the thickness of the lead frame 4 of transmission is more than the gap between detection disk roller 6-3 lower surface and transmission track 2, disk roller is detected
6-3 is lifted up, and active lever 6-2 rises therewith, and now sensor 6-4 detects active lever 6-2 ascending motion, hair
Go out signal to controller, and control alarm to send alarm by controller.
In order to be detected to active lever 6-2 state, the sensor 6-4 can be height sensor 6-4,
Displacement transducer 6-4 or other be capable of detecting when the sensor 6-4 of active lever 6-2 liftings.But in view of easy implementation and into
This reason for, in a preferred embodiment of the invention, the sensor 6-4 are photoelectric sensor.The photoelectric sensor is sent out including light
Emitter, optical receiver and detection circuit composition.Wherein residing for the upper surface of level height residing for optical transmitting set and active lever 6-2
Certain difference in height between level height be present, the difference in height is less than the thickness of lead frame 4 to be sent.Optical receiver and light
Transmitter is in same level height, and the input of circuit and controller connects the output end of the optical receiver after testing.Light is sent out
Emitter persistently sends out optical signal：When active lever 6-2 is under non-lifting state, the optical signal that optical transmitting set is sent is not
It is blocked, optical receiver can not receive the optical signal reflected, and detection circuit can not detect what optical receiver returned
Signal, therefore do not send signal or send non-lamination signal to controller；When active lever 6-2 is under lifting state, light
The optical signal that transmitter is sent reflects because being blocked by active lever 6-2, and optical receiver receives this and reflected
Optical signal and be sent to detection circuit, the signal that is returned to optical receiver of detection electric circuit inspection, and send lamination signal to controlling
Device processed.
The controller and alarm can be the controller and alarm specially set, can also directly use former paster
The controller and alarm that machine carries in itself.Life is informed in time in order to which chip mounter to the lamination phenomenon of lead frame 4 to occur
Worker is produced, the alarm is audible-visual annunciator.But the report that alarm is sent may be ignored because busy in view of direct labor
Alert signal, the controller is also connected with the halt switch of chip mounter, so when anti-stacked framework testing agency detects lead frame
When lamination occurs in frame 4, controller sends signal and goes to control chip mounter to shut down, to avoid the appearance of substandard product, and therefore
The waste of caused lead frame 4 and chip 5.
