Technical field
The present invention relates to sucker by the fixed technical field of object, and in particular to a kind of sucker fixed structure and sucker are solid
Determine method.
Background technology
Currently, generally there are two types of fixing means for sucker：1, body surface is directly attached to by glue etc.；2, single sucker is worn
Hole allows sucker to show outside product, and sucker bottom stays in inside product, is then pushed down with briquetting；
The shortcomings that prior art is：The first scheme：Sucker is bonded in body surface by adhesives such as glue, exists
Two problems:First, it is easy to be torn, detach；Second, the time is grown, and glue is done, it is easier to fall；Absorption is not achieved
Effect.Second scheme：Add man-hour requirement that single sucker is passed through preformed hole one by one, efficiency is very low, is not easy to produce, and
It is easy to generate injury to sucker.
Chinese patent CN 207206250U disclose a kind of multi-sucker formula workpiece fixed mechanism, including a sucker fixes machine
Structure, sucker fixing mechanism include a fixed plate, and sucker is equipped in fixed plate, and sucker is equipped at least nine；At least nine suckers
In a sucker be located at the center of fixed plate, with positioned at the sucker in fixed plate center for the first sucker, the first sucker and the first suction
The air entry of pneumatic module is connected；At least nine suckers further include the second sucker group positioned at the first sucker periphery, the second sucker group
Sucker be connected with the air entry of the second getter assembly；At least nine suckers further include that the third positioned at the second sucker group periphery is inhaled
Disk group, the sucker of third sucker group are led by third air intake duct across fixed plate and the air entry of third getter assembly respectively
It is logical.The technical solution controls different suckers by multiple independent getter assemblies, convenient for the size for different workpiece, fits
When the fixed workpiece of adjustment sucker number.However batch sucker in the multi-sucker formula workpiece fixed mechanism be required for
Air intake duct connects, and structure is complex, and using also not convenient enough.
Chinese patent CN 105972043A disclose a kind of sucker fixing, including sucker disk seat and setting in sucker disk seat
Interior sucker ontology, sucker ontology include negative pressure seat and sucker rubber panel, and the negative pressure cavity of bottom opening is equipped in negative pressure seat,
