In some production lines with high automation degree, screws are conveyed to the positions of the chucks through the automatic feeding mechanisms and then are screwed by the electric screwing guns, and the situation that a plurality of screws are conveyed once or the screws are not conveyed to the chucks exists in automatic screw feeding. The existing detection method can not detect the condition of putting more screws generally, and the electric tightening gun is still tightened, so that beat waste and unnecessary reworking are caused.
Therefore, a mistake proofing device for automatic screw feeding needs to be designed to prevent the situation that the screws are placed more and more in a missing manner.
Disclosure of Invention
The utility model aims at overcoming the not enough of prior art, providing an automatic change mistake proofing device of screw material loading to prevent that the screw from putting more, leaking the condition of putting.
In order to achieve the aim, the utility model provides an automatic change mistake proofing device of screw material loading, the loach carrying platform comprises a supporting fram, servo electric jar, electronic rifle of screwing up, criticize the head, a spring, detect the ring, detect the sensor, servo electric jar, it installs on the support frame to detect the sensor, the axle and the electronic rifle of screwing up of servo electric jar are connected, install on the rifle head of electronic rifle of screwing up and criticize the head, detect the ring and fix the periphery of criticizing the head, the spring housing is established outside criticizing the head to be located the rifle head of electronic rifle of screwing up and detect between the ring, detect the mounting height of sensor and the position matching that detects the ring.
The shaft of the servo electric cylinder is connected with one end of the connecting plate, and the electric tightening gun is installed on the connecting plate.
The detection sensor is a proximity switch, and the model is BES001J.
A chuck is arranged below the screwdriver head, and a screw is placed in the chuck.
The batch head is coaxial with the chuck.
The electric tightening gun is one of an elbow type electric tightening gun, a straight type electric tightening gun or a gun type electric tightening gun.
Compared with the prior art, the utility model, detect whether have the screw to put more, leak the condition of putting through detecting the sensor, detecting the ring, avoid causing the beat extravagant, reduce the rework. The utility model has the advantages of compact structure and convenient use.
Drawings
Fig. 1 is a schematic view of the present invention.
Detailed Description
The present invention will now be further described with reference to the accompanying drawings.
Referring to fig. 1, the utility model provides an automatic change mistake proofing device of screw material loading, which comprises a supporting rack, servo electric jar, electronic rifle of screwing up, criticize the head, a spring, detect the ring, detect the sensor, servo electric jar 1, it installs on support frame 9 to detect sensor 5, servo electric jar 1's axle and electronic rifle 2 of screwing up are connected, install on the rifle head of electronic rifle 2 of screwing up and criticize head 6, detect ring 4 and fix the periphery at criticizing head 6, 3 covers of spring are established outside criticizing head 6, and lie in electronic rifle 2's of screwing up rifle head and detect between the ring 4, detect sensor 5's mounting height and the position matching that detects ring 4.
The utility model discloses in, in order to facilitate the connection, servo electric cylinder 1's axle is connected with the one end of connecting plate, and electronic rifle 2 of screwing up is installed on the connecting plate.
The detection sensor 5 is a proximity switch and has a model number BES001J. The detection ring 4 is matched with the detection sensor 5, when the detection ring 4 and the detection sensor 5 are at the same horizontal height, the detection sensor 5 outputs signals, and the equipment normally operates; when the positions of the detection ring 4 and the detection sensor 5 are staggered, the detection sensor 5 outputs no signal, the equipment stops running and gives an alarm, and the number of screws is checked manually.
In order to guarantee the accuracy of the detection, the batch head 6 is coaxial with the collet 8.
The utility model discloses in, electronic rifle 2 of screwing up is the electronic rifle of screwing up of elbow formula, the electronic rifle of screwing up of straight formula or one of the electronic rifle of screwing up of rifle formula.
During debugging, the servo electric cylinder 1 drives the electric tightening gun 2 to move downwards, so that the end part of the batch head 6 descends to the processing hole b from the batch head position a in the chuck 8, the position of the detection sensor 5 is adjusted to be at the same horizontal height with the detection ring 4, and the detection sensor 5 detects the detection ring 4 and sends a signal; meanwhile, a verification test can be performed in which the detection sensor 5 cannot output a signal when the batch head 6 moves downward by a distance exceeding or shorter than the distance from the batch head a to the processing hole b.
The utility model discloses at the during operation, the below of criticizing head 6 is provided with chuck 8, has placed screw 7 in the chuck 8. The screw 7 is delivered to the chuck 8 by an automatic feeding mechanism. Servo electric cylinder 1 drive is electronic screws up rifle 2 and is reachd operating position, if place in the chuck 8 is a screw 7, criticize head 6 and can push up screw 7 from criticizing head a to the processing hole department b, criticize head 6 atress compression, drive and detect 4 relative upward movements of ring, the spring 3 degree of compression is the same with the debugging degree, thereby make detection sensor 5 and detection ring 4 make detection sensor 5 detect detection ring 4 and send out the signal at same level, equipment normal operating.
If screw 7 is not placed in chuck 8, the distance of batch head 6 downstream can exceed from batch head a to the distance of processing hole department b, and the force that spring 3 received is less during than debugging, and the distance that drives the relative upward movement of detection ring 4 is also little, and the position of detection ring 4 and detection sensor 5 can stagger, no signal output, and equipment stop operation and warning are examined the quantity of screw 7 by the manual work.
If two or more screws 7 are placed in the chuck 8, the distance of the downward movement of the batch head 6 is shorter than the distance from the batch head a to the processing hole b, the force applied to the spring 3 is larger than that in debugging, the distance of the relative upward movement of the detection ring 4 is also larger, the positions of the detection ring 4 and the detection sensor 5 are staggered, no signal is output, the equipment stops running and gives an alarm, and the number of the screws 7 is checked manually.
The utility model discloses a detect the sensor, detect the ring and detect whether have the screw to put more, leak the condition of putting, avoid causing the beat extravagant, reduce the rework. The utility model has the advantages of compact structure and convenient use.
