Disclosure of Invention

The design purpose is as follows: the defects in the background art are avoided, and the gantry plane type grabbing structure capable of automatically selecting the grabbing force of the grabbing head according to the weight of the grabbed workpiece is designed.

The design scheme is as follows: in order to achieve the above design objectives. The utility model discloses in structural design: firstly, the cut workpiece waits for the automatic grabbing machine to grab on the exchange platform; secondly, the vacuum suckers or the electromagnetic suckers are distributed along the circumference of the rotating large disc, and the corresponding vacuum suckers or the corresponding electromagnetic suckers are respectively selected according to the size parameters of the shapes and the sizes of different workpieces; thirdly, after a corresponding vacuum sucker or electromagnetic sucker is selected, the sliding table is lowered to the position of the workpiece to suck or grab the workpiece; fourthly, according to the characteristic requirements of a subsequent polishing host machine, angle adjustment can be carried out on the grabbed workpiece; and fifthly, adjusting the ascending sliding table, moving the portal frame to place on the conveying platform after the workpiece ascends, and entering the host machine for processing.

1. The rotary large disc is connected with the lower ends of the upper sliding frame and the lower sliding frame and is driven by a servo motor to rotate, and the rotary large disc is one of the technical characteristics of the utility model. The purpose of this design is: the weight of the cut metal workpiece is different due to different thicknesses and sizes, and if the same sucking disc or electromagnetic sucking disc is adopted for grabbing, the weight of the cut workpiece is higher than the technical parameters set by the sucking disc or the electromagnetic sucking disc, and the cut workpiece is not sucked; if the weight of the cut workpiece is less than the technical parameters set by the suction disc or the electromagnetic suction disc, the size is small, and the energy consumption is wasted; if the weight of the cut workpiece is between the technical parameters set by the suction disc or the electromagnetic suction disc, no safety system exists, and the accident of grabbing and dropping is easy to happen. For this reason, the utility model discloses the equidistant or unequal interval of lower terminal surface at rotatory big dish is equipped with the sucking disc of variation in size or the electromagnetic chuck of variation in size, and the suction diverse of the sucking disc of this variation in size or the electromagnetic chuck of variation in size all is controlled by the PLC controller, and the PLC controller converts weight parameter according to receiving the parameter automation by the cutting work piece, and after selecting corresponding sucking disc or electromagnetic chuck according to weight parameter, make by the rotation of servo motor's rotatory big dish under the rotatory big dish correspond sucking disc or electromagnetic chuck rotate the face top of being snatched the work piece on the terminal surface, and then from having avoided the weak point that the background art exists according to last. 2. The design of the universal adjustable angle of the vacuum chuck or the electromagnetic chuck is the second technical characteristic of the utility model. The purpose of this design is: when the vacuum chuck or the electromagnetic chuck on the lower end surface of the large rotating disc is in universal fit with the lower end surface of the large rotating disc, the vacuum chuck or the electromagnetic chuck can be reliably matched with a cut workpiece surface, so that the situation that the suction force of the vacuum chuck or the suction force of the electromagnetic chuck cannot lose efficacy is ensured; secondly, according to the characteristic requirement of the follow-up polishing host, the angle of the grabbed workpiece can be adjusted.

The technical scheme is as follows: the utility model provides a planer-type planar snatchs structure, includes the PLC controller, the PLC controller embeds there is parameter weight conversion computational formula, and upper and lower carriage assembly is on the gantry carriage, and rotatory big dish is connected and is rotated by the servo motor drive with upper and lower carriage lower extreme, and servo motor is controlled by PLC, and a plurality of vacuum chuck or electromagnet distribute under rotatory big dish terminal surface and a plurality of vacuum chuck or electromagnet work whether be controlled by the PLC controller.

Compared with the prior art, the utility model, avoided the weak point that the background art exists, realized according to by the vacuum chuck or the electronic chuck of cutting work piece weight safety, selecting different suction automatically.

Detailed Description

Example 1: reference is made to figures 1-6. The utility model provides a planer-type planar snatchs structure, includes the PLC controller, the PLC controller embeds there is parameter weight conversion computational formula, and upper and lower carriage 3 assembles on longmen carriage 2, and rotatory big dish 5 is connected and is rotated by the servo motor drive with upper and lower carriage 3 lower extreme, and servo motor is controlled by PLC, and a plurality of vacuum chuck or electromagnetic chuck 4 distribute terminal surface and a plurality of vacuum chuck or electromagnetic chuck 4 work under rotatory big dish 5 and whether be controlled by the PLC controller.

The sucking/gripping disk 4 is a vacuum chuck or an electromagnetic chuck, and the manufacturing of the vacuum chuck or the electromagnetic chuck is prior art and will not be described herein.

The sizes of the vacuum suckers or the electromagnetic suckers 4 distributed on the lower end surface of the large rotating disc 5 are different, namely the sizes of the vacuum suckers or the electromagnetic suckers 4 are different to represent that the respective suction forces are different, and the suckers are large and the suction forces are large; the sucking disc is little, suction is little.

The angle of the vacuum chuck or the electromagnetic chuck is universally adjustable, namely, the angle of the grabbed workpiece can be adjusted according to the characteristic requirement of a subsequent polishing host.

A grabbing method of a gantry type plane grabbing structure comprises the steps that when a plate on an exchange platform 7 needs to be cut, required cutting parameters are input into a PLC (programmable logic controller), the PLC instructs a cutting machine to cut to obtain a cut workpiece 6 with a required size, the weight of the cut workpiece 6 is calculated according to a calculation formula arranged in the PLC, the PLC automatically selects the size of a vacuum chuck or the size of an electromagnetic chuck needed for grabbing the cut workpiece 6 according to the weight of the cut workpiece 6, a servo motor is instructed to drive a rotary large disc 5 to rotate, the selected vacuum chuck or electromagnetic chuck 4 is rotated to the cut workpiece 6, then an upper sliding frame 3 and a lower sliding frame 3 are instructed to slide downwards to enable the selected vacuum chuck or electromagnetic chuck 4 on the lower end face of the rotary large disc 5 to be matched with the face of the cut workpiece 6, and the PLC instructs a vacuum generator to work, the vacuum sucker connected with the vacuum generator is combined with the surface of the cutting workpiece by negative pressure to achieve the purpose of grabbing the workpiece, or the PLC instructs the electromagnetic sucker on the lower end surface of the rotary large disc 5 to be electrified to generate suction force to grab the cutting workpiece 6.
