As shown in fig. 1 and 2, the storage battery G is a lithium storage battery of type 12V/10Ah, the charging socket CZ is a coaxial power socket, the power switch S1 is a coaxial power switch, and the jack of the charging socket CZ and the operating handle of the power switch S1 are located outside the two openings at the front end of the element box 8. Among a plurality of photoelectric switches of the multi-directional probe, a plurality of photoelectric switches A, A1 are connected with the positive power supply input end 1 of the AN, a plurality of photoelectric switches A, A1 are connected with the negative power supply input end 2 of the AN, the photoelectric switches A, A1 and the AN are PNP type reflective photoelectric switch sensor finished products with the model E3F-DS30C4, the photoelectric switches A, A1 and the AN are provided with two power supply input ends 1 and 2 and a high level output end 3, infrared light beams emitted by a transmitting head of a detecting head at the front end of the photoelectric switches are blocked by AN article when the photoelectric switches work, the high level or no high level is output when a receiving head at the front end of the detecting head receives rear high level output end 3, and the high level or no high level is output when no article blocks; the photoelectric switch A, A1 and AN have a maximum detection distance of 50cm (35 cm in this embodiment), and AN adjusting knob is provided in the housing, wherein the detection distance of the adjusting knob is closer when the adjusting knob is adjusted to the left and farther when the adjusting knob is adjusted to the right. The inner diameter of the inner ring of the ring magnet 72 is larger than the outer diameter of the six-axis robot arm 101. The control circuit comprises a plurality of relays K, K1, KN and K2 (seven relays in the embodiment), a plurality of relays K, K1, KN and K2, wherein the relays K, K1 and the KN control power supply input ends are connected, the relays K, K1, KN and K2 are connected with the negative power supply input ends, and the normally open contact ends of the relays K, K1 and KN are connected with the positive power supply input end of the last relay K2.
As shown in fig. 1 and 2, two poles of the storage battery G and two ends of the charging socket CZ are respectively connected through leads (when the storage battery G is out of power, an external 12V power charger plug can be inserted into the charging socket CZ to charge the storage battery G). The positive electrode of the storage battery G is connected with one end of a power switch S1 through a lead. The other end of the power switch S1, the cathode of the storage battery G, and power input ends 1 and 2 pins of the photoelectric switches A, A1 and A2 of the multi-directional probe, and the control power input ends of the power input end relays K, K1 and KN and the cathode power input end of the control circuit are connected through leads. Pins 3 of the photoelectric switches A1, A2 and AN at the multi-path signal output end of the multi-direction probe and the positive power supply input ends of the relays K, K1 and KN at the multi-path signal input end of the control circuit are respectively connected through leads. The trigger signal output end relay K, K1 and the KN normally open contact end of the control circuit are respectively connected with the cathode of the storage battery and the power input end of the annunciator B through leads. Two control power input ends of a signal input end relay K2 of the control circuit are connected with a main power switch (220V input power) of the six-axis robot body through leads, and a control signal output end relay K2 of the control circuit is connected with a main power input end of the six-axis robot body M through leads. The main power input end of the six-axis robot body M is connected with the main power input end through a main power switch SK through a lead, and the power switch SK is in an open circuit state during normal work at ordinary times.
As shown in fig. 1 and 2, other using methods and processes of the novel six-axis robot body are completely consistent with those of the existing six-axis robot, and the six-axis robot body clamps, carries or stacks goods through forearms by self functions under the action of internal programming or manual and wireless control modes. Before the robot is used, technicians adjust the positions of the multi-directional probes on the robot arm to enable the forearms of the six-axis robot body to move, and when the probes collide with a discharge station or a stacking station at risk, the probes of one or more photoelectric switches can detect the probes. During actual work, when the six-axis robot body works, the distance between the goods which are clamped and carried by the front-end forearms of the six-axis robot body and a carriage or a stacking station exceeds a certain time (for example, exceeds 35cm), and due to the fact that no obstacle exists in front of the detection heads of the photoelectric switches (A, A1 and AN) and 3 pins of the photoelectric switches cannot be blocked by the obstacle, the high level cannot be output, the relays K, K1 and KN cannot be electrified to attract the control power supply input end and the normally open contact end of the control power supply to be open, and the buzzer B and the relay K2 cannot be electrified to work.
As shown in fig. 1 and 2, in AN actual situation, when the six-axis robot body grips and carries goods, no matter the six-axis robot body approaches other articles leftwards, rightwards, upwards or downwards or is too close to a goods loading and unloading station, the distance is less than a certain time (for example, less than 35cm), after the 3 feet of the corresponding photoelectric switch a or a1 or AN output high level, one or more of the relays K or K1 or KN are powered and closed. Because the normally open contact ends of the relays K or K1 and KN are connected with the positive power input end of the annunciator B and the relay K2, under the actual condition, as long as any position of the forearm of the six-axis robot is close to an object, the buzzer B and the relay K2 are powered. After the relay K2 is electrified and closed, the two control power supply input ends and the two normally closed contact ends are opened, and the buzzer B is electrified to work and then gives out a loud prompt sound. Because, two normally closed contact ends of relay K2 are connected with six axis robot body M's total power input end, so, six axis robot body press from both sides and get the certain distance before the transport goods is close to object or the loading and unloading station, and six axis robot body M all can lose the electricity and no longer work, has prevented that the goods of pressing from both sides or getting or transport from being close to and then leading to the collision near other objects, causes the damage of the goods of pressing from both sides and getting the transport or six axis robot body. After the sounder B sounds, a worker can intuitively know that the forearms of the six-axis robot body and the clamped goods are close to other objects at the first time by hearing the sound, and then subsequently perform targeted operation to reduce the probability of damage of the goods or the six-axis robot body (if the worker manually controls the working mode of the six-axis robot body, the worker can control the operation in the opposite direction to prevent the six-axis robot body or the goods from being damaged), if the six-axis robot body is in programming control, a technician can temporarily turn on a main power switch SK connected with a main power input end of the six-axis robot body M, then perform targeted operation to enable the forearms or the goods of the six-axis robot body to be separated from other objects to a safe distance, and finally turn off the power switch SK). This novel technical personnel carry on need close switch S1 when to the operation, adjust six robot body forearms and goods or loading and unloading station position after, open switch S just before next use. In fig. 2, the buzzer B is an active continuous audible alarm finished product of a model SF-12, and the relays K, K1, K2 and KN are DC12V relays.
