Detailed Description

The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The utility model is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

The utility model aims to provide a steel back placing mistake proofing device for a friction plate, aiming at the defects of the prior art.

Example one

The embodiment provides a steel backing mistake proofing device is put to friction disc, as shown in fig. 1, including manipulator 1, mould 2, steel backing 3 places on mould 2 through manipulator 1.

As shown in fig. 2-3, which are schematic structural diagrams of the mold, the mold 2 is a box structure, a position for placing the steel back 3 is preset on a platform on the upper surface of the mold, a positioning block 21 for positioning is arranged on the platform, and the positioning block 21 is used for determining the position for placing the steel back 3; in this embodiment, two positions for placing the steel back 3 are provided on the platform, and each position is positioned by 4 positioning blocks 21.

As shown in fig. 4-5, which are schematic structural diagrams of the manipulator, the manipulator 1 includes a mounting plate 11, a cylinder 12, a sensor 13, a probe 14, and an electromagnet 15.

The mounting plate 11 has a square structure and is used for mounting other components in the robot 1.

The electromagnet 15 is arranged below the mounting plate 11, two electromagnets 15 are arranged below the mounting plate 11 in this embodiment, and the mounting position of the electromagnets 15 corresponds to the position of the steel back 3 on the mold 2, so that the steel back 3 adsorbed on the electromagnet 15 can be accurately placed at a proper position of the mold 2.

The number of the sensors 13 is 4, and the 4 sensors are respectively arranged at the periphery (four corners) of the square structure of the mounting plate 11; the number of the probes 14 is 4, the 4 probes 14 are respectively arranged at the periphery (four corners) of the square structure of the mounting plate 11, and one probe 14 is electrically connected with one sensor 13; in this embodiment, a spring is provided at the top end of each probe 14, and the spring is used for assisting the probe 14 to move up and down; the sensor 13 is combined with the probe 14 to detect whether the position of the steel back 3 adsorbed on the electromagnet 15 is in place, if so, the processing is not carried out, and the next procedure is continued; if not, the device is suspended and gives an alarm to wait for the handling of the operator.

In this embodiment, the mounting plate 11 has mounting holes near four corners, and the top ends of the probes 14 are disposed in the mounting holes; the bottom end of the probe 14 is arranged outside the mounting hole, and the length of the bottom end of the probe extending out of the mounting hole is larger than or equal to the total thickness of the electromagnet and the steel backing.

The cylinder 12 is arranged above the mounting plate 11, preferably at the middle position above; the piston rod of cylinder 12 and mounting panel 11 fixed connection to make cylinder 12 drive mounting panel 11 up-and-down motion under the up-and-down motion of piston rod, and then make mounting panel 11 drive electro-magnet 15 up-and-down motion, so that adsorb steel backing 3 on electro-magnet 15 and place corresponding position in mould 2 in.

The steel backing mistake proofing device is put to friction disc of this embodiment's concrete implementation mode does:

when the steel back needs to be pressed, the steel back is adsorbed on the electromagnet, then the controller connected with the air cylinder controls the air cylinder to move, the air cylinder drives the mounting plate to enable the mounting plate to drive the steel back on the electromagnet to move downwards so as to enable the steel back to be placed on the mold, the sensor and the probe detect the position of the steel back at the moment, whether the position of the steel back adsorbed on the electromagnet is in place or not is judged according to a detection result, if not, the device is paused and gives an alarm to wait for an operator to process the steel back; if yes, the device continues to work without processing.

The detection of whether the sensor and the probe are in place is specifically as follows: storing an accurate probe distance value in advance, when the steel backing is placed on a mold, acquiring a retraction distance when the probe is contacted with the surface of the mold by using a sensor, and if the retraction distance is the same as a preset distance value, considering that the position is in place; if the retracting distance is different from the preset distance value, the position is not in place.

The explanation is given with specific numerical values:

assuming that the preset distance value is 10mm, when the steel backing is arranged at the position corresponding to the mold, the sensor acquires the retraction distance when the probe contacts the surface of the mold, and if the retraction distance is 10mm, the position is in place; if the retraction distance is not 10mm (e.g., 6mm), it is considered to be out of position.

It is to be noted that the foregoing description is only exemplary of the utility model and that the principles of the technology may be employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the utility model. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
