A kind of plate grabbing device
Technical field
The utility model belongs to manipulator technical field more particularly to a kind of plate grabbing device.
Background technology
Various plates are had in automobile production workshop, and all need to carry out Thickness sensitivity there are many plate.Exist at present
It is main that plate crawl is got up using the manipulator with big sucker when carrying out Thickness sensitivity to plate, then utilize sensing contact
Device carries out sheet thickness detection.Wherein when capturing plate, manipulator is moved to above plate, is then dropped to and is allowed big sucker
Manipulator is contacted, then big sucker is vacuumized, to draw plate.But, plate is being captured and is being examined at present
When survey, since sucker structure is single, in addition equipment itself will produce the factors such as vibrations, it is easy to cause the plate that crawl is got up and occurs
It tilts, moreover, because being easily adhered between plate, it is also possible to will appear the situation for capturing extra quality (two pieces of plate material), influence follow-up
Production and processing.
Utility model content
The utility model be in order to overcome deficiency in the prior art, provide it is a kind of simple in structure, can be effectively to plate
It being captured and is detected, crawl process is stablized, and can ensure that the horizontality of plate is good and can carry out sheet thickness detection, to prevent
Only capture extra quality plate grabbing device.
To achieve the goals above, the utility model uses following technical scheme:
A kind of plate grabbing device, including mainframe, be arranged mainframe bottom mounting disc and it is several setting installing
Pumping sucker on disk, the pumping sucker include sucker, the sucker disk seat being connect with sucker and be arranged on sucker disk seat and
The adsorption plane of air extraction connector for being docked with pumping tracheae, sucker is in below mounting disc, is set on the adsorption plane of sucker
There are bleeding point, air extraction connector to be connected to bleeding point by the bleed-off passage being arranged on sucker disk seat, mounting disc is equipped with contact and passes
Sensor.For contact sensor for detecting whether crawl has played plate, can be used for detection sheet thickness etc. (can replace sensing
The form of device, as long as detection function can be realized).Plate is adsorbed from three using three suckers, can ensure suction
Attached effect and the stability and level that plate can be maintained.Air extraction connector is taken out for docking pumping tracheae, pumping tracheae for connecting
Gas equipment, such as aspiration pump.
Preferably, the mounting disc is connected and fixed by several attachment screws with mainframe.It is connected with attachment screw,
Easy to disassemble and installation.
Preferably, the mounting disc is equipped with centre bore, at the centrally disposed hole of contact sensor, it is evacuated sucker number
It is three.Contact sensor, which is at center, to be more conducive to improve testing result precision.
Preferably, respectively pumping sucker is in sustained height, each sucker that is evacuated is along the uniform annular distribution of centre bore.Each pumping
The uniform annular distribution of sucker can ensure that absorption position is uniform, and adsorption effect can be improved and ensure testing result precision.
Preferably, the mounting disc is equipped with several sliding slots corresponding with pumping sucker, inhaled in pumping in correspondence with each other
In disk and sliding slot:Sucker disk seat is in sliding fit with the sliding chute, and the slidably direction of sucker disk seat is horizontal, and sucker disk seat is equipped with fixing screws,
Fixing screws include with the stud of sucker disk seat screw-thread fit and with the co-axially fixed head of screw of stud, head of screw is in mounting disc
Side and compression mounting disc.
Preferably, the slidably angular separation of two neighboring sucker disk seat is at 120 degree.It is such then can ensure three sliding slots
It is cyclic annular uniformly distributed, facilitates balance when adjusting and adsorbed after being adjusted conducive to guarantee plank.
The utility model has the beneficial effects that:It is simple in structure, can effectively plate be captured and be detected, be captured
Cheng Wending can ensure that the horizontality of plate is good and ensure that testing result accuracy is high.

Specific implementation mode
The utility model is further described with reference to the accompanying drawings and detailed description.
Embodiment 1:In embodiment as shown in Figure 1 to Figure 2, a kind of plate grabbing device, including mainframe 1, setting exist
The mounting disc 2 of mainframe bottom and several pumping suckers 3 being arranged in mounting disc, the pumping sucker include sucker 31,
The sucker disk seat being connect with sucker and the air extraction connector 33 for being arranged on sucker disk seat 32 and being used to dock with pumping tracheae, sucker
Adsorption plane be in below mounting disc, the adsorption plane of sucker is equipped with bleeding point, and air extraction connector is by being arranged on sucker disk seat
Bleed-off passage be connected to bleeding point, mounting disc be equipped with contact sensor 34.Contact sensor is for detecting whether capture
Plate can be used for (form of sensor can be replaced, as long as detection function can be realized) such as detection sheet thicknesses.
The mounting disc is connected and fixed by several attachment screws 4 with mainframe.It is connected with attachment screw, it is easy to disassemble
And installation.The mounting disc is equipped with centre bore, and at the centrally disposed hole of contact sensor, pumping sucker number is three.It connects
Tactile sensor, which is at center, to be more conducive to improve testing result precision.Each pumping sucker is in sustained height, each to be evacuated sucker edge
The uniform annular distribution of centre bore.Each pumping uniform annular distribution of sucker can ensure that absorption position is uniform, can be improved adsorption effect
And ensure testing result precision.
When work, mechanical hand-motion the utility model is moved to above plate, and the utility model declines, the suction of each sucker
Attached face contacts panel surface, starts to be evacuated.When starting pumping, contact sensor can start to detect plate with the presence or absence of (whether having
Plate can be crawled) and detection sheet thickness (, detection thickness is primarily to detect whether to have captured extra quality, i.e. two boards.It lifts
Example:Thickness can be detected according to the falling head of the induction end of contact sensor, if without plate, declining setpoint distance will not
Object is touched, if there is one piece of plate, plate will be contacted by declining setpoint distance, if there is two pieces of plate material, be had not degraded
Setpoint distance will touch plate).After the completion of vacuumizing, the utility model rising can take up plate.
Embodiment 2:The basic structure of the present embodiment with embodiment with embodiment 1, the difference is that, in Fig. 3
Shown, the mounting disc is equipped with several sliding slots 5 corresponding with pumping sucker, in pumping sucker and sliding slot in correspondence with each other:
Sucker disk seat is in sliding fit with the sliding chute, and the slidably direction of sucker disk seat is horizontal, and sucker disk seat is equipped with fixing screws, and fixing screws include
With the stud of sucker disk seat screw-thread fit and with the co-axially fixed head of screw of stud, head of screw is in above mounting disc and compresses installation
Disk.The slidably angular separation of two neighboring sucker disk seat is at 120 degree.It is such then can ensure three sliding slots be also it is cyclic annular uniformly distributed,
Facilitate balance when adjusting and adsorbed after being adjusted conducive to guarantee plank.
When fixing screws are tightened, sucker disk seat can not slide, and when fixing screws are unscrewed, sucker disk seat can be slided to adjust
Position, to which the utility model adapts to the crawl of a variety of size plates.
