The utility model discloses save the mode that micro-gap switch wiring was to the control grillage, like this, both saved the space greatly, also simplified the structure, more reduceed manufacturing cost, be fit for being extensively promoted and used.
Description
Technical Field
The utility model relates to a mechanical equipment technical field, in particular to arm zero point coordinate location structure.
Background
Along with the development of novel unmanned automatic retail equipment, the mode that the arm got goods shipment is also more and more popularized, the arm is in the production equipment, it needs to have a zero coordinate in order to raise the efficiency to debug the upgrading in-process, and present arm limit structure at zero point is the micro-gap switch of direct installation on the arm structure, but this kind of structural style has very big limitation, need great structural space, have to realize with the mode of sacrificing structural strength or increasing the structure even, cause the waste in space and cost, for this reason, we propose an arm zero coordinate location structure.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides a mechanical arm zero coordinate location structure, the turned angle of the transmission shaft of forearm motor and big arm motor corresponds the shift position of arm, therefore when the arm moves to zero coordinate position, the opto-coupler inductive switch contact on corresponding motor drive shaft angle and the control grillage, thereby produce electronic signal, confirm zero coordinate, this structure omits the mode that micro-gap switch wired to the control grillage, and thus, the space has both been saved greatly, and the structure has also been simplified, and more reduced manufacturing cost, can effectively solve the problem in the background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
The utility model provides an arm zero point coordinate location structure, includes mounting panel, control grillage and opto-coupler inductive switch, install the control grillage through the mounting bracket in the mounting panel, opto-coupler inductive switch is installed through the bolt in control grillage bottom, mounting panel one side is connected with the forearm motor through the link, the mounting panel opposite side is connected with big arm motor through the connecting seat, the mounting panel bottom is connected with big arm through the pivot, the forearm is connected through the pivot in big arm bottom.
Furthermore, the transmission shafts of the small arm motor and the large arm motor are both positioned at the bottom end of the control plate frame, and the distances between the transmission shaft of the small arm motor and the transmission shaft of the large arm motor and the optical coupling induction switch are both 5-10 mm.
Further, a transmission shaft of the large arm motor is in transmission connection with the large arm.
Further, a transmission shaft of the small arm motor is in transmission connection with the small arm.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. The rotation angles of the transmission shafts of the small arm motor and the large arm motor correspond to the moving positions of the mechanical arm, so that when the mechanical arm is operated to the zero-point coordinate position, the corresponding motor transmission shaft angle is in contact with the optical coupling induction switch on the control plate frame, an electronic signal is generated, and the zero-point coordinate is confirmed.
2. The structure omits the mode that the microswitch is connected to the control plate frame, thus greatly saving space, simplifying the structure and reducing production cost.
