Wherein, the vibrating disc 11 and the orbital vibrator 12 are conventionally arranged in the field, the vibrating disc 11 vibrates and rotates so as to transport the screws into the orbital vibrator 12 one by one, and the orbital vibrator 12 transports the screws through vibration and a certain inclination to the discharge end of the orbital oscillator 12 .

A discharge turntable 131 is provided at the discharge end of the orbital vibration straightener 12 . The discharge turntable 131 is a preferred arrangement, and its function is to arrange a plurality of screws in an orderly manner, so as to facilitate the access of the screw locking assembly 2 .

The discharge turntable 131 is a part of the discharge mechanism 13 .

Referring to FIG. 3 , the discharge mechanism 13 includes a discharge turntable 131 and a discharge motor 132 that drives the discharge turntable 131 to rotate. A plurality of screw insertion holes 1311 are provided on the outer peripheral side of the discharge turntable 131 . The inner diameter of the screw insertion hole 1311 is approximately equal to the diameter of the screw portion of the screw, so the screw rod of the screw can be clamped in the screw insertion hole 1311 .

In other technical solutions, the screw insertion holes 1311 can also be arranged not on the outer peripheral side of the discharge turntable 131, but on the disk surface of the discharge turntable 131, and the discharge end of the orbital oscillator 12 is placed on the discharge turntable. 131 above the plate surface, so that the screws fall into the screw insertion holes 1311.

Referring to FIG. 2 , the discharge turntable 131 and the discharge motor 132 in FIG. 3 are placed in the housing 15 in FIG. 2 . A retainer 14 is provided on the top of the housing 15 .

As shown in FIG. 8 and FIG. 9 , the elastic connection between the guide rod 223 and the guide cylinder 221 is shown as a second spring 228 disposed between the guide rod 223 and the guide cylinder 221 . Specifically, the outer periphery of the front end of the guide rod 223 is provided with a second spring 228 in the guide cylinder 221 . And due to the functions of the above-mentioned latch 229 and the elongated hole, the guide rod 223 and the guide cylinder 221 will not be separated.

When the screw is locked, the guide rod 223 and the guide cylinder 221 move downward together. When the screw adsorbed under the magnetic member 222 contacts the workpiece, the guide cylinder 221 contacts the back plate and stops moving downward, and the guide rod 223 continues to move down and the bit The portion 2231 is clamped with the screw, and then the locking motor 225 rotates to drive the batch head 2231 to rotate, thereby driving the screw to rotate to complete the locking of the screw.

After the screw locking is completed, the guide rod 223 moves upward due to the action of the first spring 227 (see below for details), and the guide cylinder 221 does not move temporarily due to the action of the second spring 228 until the guide rod 223 retracts into the guide cylinder 221 Afterwards, the guide cylinder 221 moves upward away from the back plate.

Therefore, the main function of the second spring 228 is to ensure that the guide rod 223 can be retracted into the guide cylinder 221 to prepare for the next screw locking.

In addition, as shown in FIG. 8 , in conjunction with FIGS. 6 and 7 , a first spring 227 is further provided between the guide rod 223 and the upper surface of the locking turntable 226 . As shown in FIG. 5 , when the steering rod 224 drives the guide rod 223 to move down, the first spring 227 is compressed. After the locking screw is completed, the switching rod 224 moves up, and the guide rod 223 rises due to the resilience of the first spring 227 Shift reset. Therefore, the main function of the first spring 227 is to enable the guide rod 223 to return.

As shown in FIG. 5 , the screw locking assembly 2 further includes a translation mechanism 24 . The function of the translation mechanism 24 is to enable the toggle lever 224 to move downward or upward.

The limiting sleeve 245 limits and guides the toggle lever 224 , so that the lower end of the toggle lever 224 can more accurately engage with the engaging portion 2232 of the guide lever 223 . Through the above structure, the air cylinder 242 can drive the locking motor 225 to indirectly drive the toggle rod 224 to move up and down, so that the screw locking operation can be better achieved.

Its working principle is to take Mark points on the product, that is, feature points, and the Mark points are calibrated and generated when the machine is imported. Formula, determine the model before production and switch to the corresponding formula. After the machine is ready, the vision sends the coordinates of the Mark point to the robot. After the robot obtains the coordinates, it starts to move after a series of judgments. After moving to the specified position, the coordinates are sent back Give the vision system and notify it that it can take pictures. After visually taking the Mark point, it calculates the position of the screw hole according to the product size and sends its coordinates to the robot. After the robot obtains the coordinates, it starts to move after a series of judgments. After moving to the designated position, it will be in place. The signal is sent to the PLC. At this time, the PLC controls the screw locking component to perform the screw locking action. After the tightening is completed, the PLC sends the completion signal to the robot, and the robot moves to the next screw hole position after receiving it, and so on.
