Each floating block 502 is connected with the blanking transfer beam plate 501 in a vertical sliding manner. The compression spring 503 is used for driving the slider 502 to slide downwards relative to the blanking transfer beam plate 501. The blanking transfer jaw assemblies 504 are mounted to the bottom of the corresponding slider 502. The photoelectric sensor 505 is located above the corresponding slider 502, and is used for detecting the up-down position of the slider 502. An L-shaped connection plate 506 is mounted and secured to the blanking transfer jaw assembly 504. The pressing needle 507 is mounted on the L-shaped connection plate 506 and protrudes downward. The driving end of the discharging transfer driving mechanism 508 is connected with the discharging transfer beam plate 501, so as to drive the discharging transfer beam plate 501 to reciprocate between the rotary positioning mechanism 4 and the discharging mechanism 6.
In this embodiment, the discharge mechanism 6 comprises a discharge tray (not shown in the drawings) and a discharge conveyor for conveying the discharge tray.
The rotary positioning feeding mechanism provided by the embodiment has the following working process:
s10: the initial state is as follows:
(1) a plurality of full-load trays loaded with workpieces are stacked and placed at the feeding lifting assembly 202a, specifically, the lower ends of the workpieces are inserted into the trays, and the upper ends of the workpieces are higher than the trays so as to be clamped in step S30;
(2) a plurality of qualified workpieces are placed on the material supplementing frame 8.
S20: the feeding lifting assembly 202a places the full-load trays on the feeding conveyor belt 201 layer by layer from bottom to top, and the feeding conveyor belt 201 conveys the full-load trays to a position close to the feeding transfer mechanism 3 so that the feeding transfer mechanism 3 takes workpieces;
when all the workpieces are removed, the loading conveyor 201 sends the empty trays to the tray lifting assembly 202b, and the tray lifting assembly 202b lifts and stores the empty trays layer by layer.
S30: the material transfer mechanism clamps each workpiece; specifically:
s301: the feeding transfer clamping jaw cylinder 3012 drives the two feeding transfer clamping plates 3011 to separate;
s302: the feeding transfer driving mechanism 304 drives the two feeding transfer clamping plates 3011 to move to the side positions of the upper end of the workpiece;
s303: the feeding transfer clamping jaw cylinder 3012 drives the two feeding transfer clamping plates 3011 to be close to each other and clamp the upper ends of the workpieces;
at this time, the top surface of each workpiece is slightly higher than the top surface of the feeding transfer clamping plate 3011, but the top surface of each workpiece is still lower than the bottom surface of the corresponding pressing plate 302;
s304: the lower pressure cylinder 303 extends downwards to drive each pressure plate 302 to push the top surface of the corresponding workpiece downwards, so as to ensure that the upper end surfaces of the workpieces are in a flush state.
S40: the feeding transfer driving mechanism 304 drives the feeding transfer clamping mechanism 301 to move above the carrier 401, and the feeding transfer clamping mechanism 301 releases the workpieces, so that each workpiece can be placed into the corresponding carrier 401.
S50: the blanking transfer driving mechanism 508 is matched with the rotary positioning mechanism 4 to perform angle correction on each workpiece; specifically:
s501: the blanking transfer driving mechanism 508 drives the pressing needle 507 to move to the upper part of the carrier 401 and downwards presses the workpiece;
it should be noted that, the contact area between the pressing needle 507 and the workpiece can be reduced, and correspondingly, a positioning hole matched with the pressing needle 507 can be arranged on the top surface of the workpiece, so that the pressing needle 507 can be prevented from scraping the top surface of the workpiece when the subsequent workpiece rotates;
s502: detecting whether each workpiece has been completely engaged with the corresponding carrier 401 (e.g., the protrusion 101 of the oil cup 1 does not just fall into the positioning notch 4013) by the photoelectric sensor 505;
it should be noted that, when the workpiece is not completely engaged with the corresponding carrier 401 (for example, the protrusion 101 of the oil cup 1 is located on the annular boss 4012 and cannot fall into the positioning notch 4013), the position of the workpiece is higher, and the elastic force of the pressing spring 503 must be overcome, so that the slider 502 slides upward to a higher position relative to the blanking transfer beam plate 501, and therefore, when the position of the slider 502 detected by the photoelectric sensor 505 is higher, the workpiece corresponding to the slider 502 cannot be considered to be completely engaged with the carrier 401;
similarly, when the workpiece is not completely engaged with the corresponding carrier 401, the position of the workpiece is lower, and the slider 502 slides down to a lower position relative to the blanking transfer beam plate 501 under the action of the elastic force of the pressing spring 503, so when the position of the slider 502 detected by the photoelectric sensor 505 is lower, the workpiece corresponding to the slider 502 can be considered to be completely engaged with the carrier 401, and at this time, the rotation of the carrier 401 to a specific angle is equivalent to the rotation of the workpiece to a specific angle.
S60: the rotating motor 402 drives each carrier 401 to synchronously rotate through the transmission belt 405, and in the process:
(1) at the beginning, if the workpiece is not completely engaged with the corresponding carrier 401, the carrier 401 will rotate relative to the workpiece first until the workpiece is completely engaged with the corresponding carrier 401 (for example, as the carrier 401 rotates continuously, the protrusion 101 of the oil cup 1 will fall into the positioning notch 4013 at a certain moment), and the workpiece will rotate synchronously with the carrier 401;
(2) initially, if the workpiece is already completely engaged with the corresponding carrier 401, the workpiece always rotates synchronously with the carrier 401.
S70: when all the photoelectric sensors 505 detect that the corresponding floating blocks 502 are at a lower position and each carrier 401 is at a preset angle, the rotating motor 402 can stop working;
it should be noted that, if after each carrier 401 has been rotated many times (for example, 2, 3, 4 or more times), some of the photoelectric sensors 505 still detect that the corresponding sliders 502 are at the higher positions, it can be considered that the workpiece in the carrier 401 is abnormal, and at this time, after each carrier 401 is rotated to a predetermined angle, the rotating motor 402 is stopped, and the abnormal workpiece is marked as a defective product.
S80: the blanking transfer driving mechanism 508 drives the blanking transfer clamping jaw assembly 504 to take out the workpiece from the carrier 401, and after the workpiece marked as defective is put into the recovery box 7, the qualified workpiece is put into a discharge tray of the discharge mechanism 6.
S90: if defective products exist, the discharge tray should be in a state of being not full, at this time, the blanking transfer driving mechanism 508 drives the blanking transfer clamping jaw assembly 504 to feed part of the workpieces (the angles are already placed) on the feed supplement frame 8 into the discharge tray, so that the discharge tray is fully loaded, and finally, the discharge conveyor belt sends all the workpieces meeting the placing angle requirement to downstream automatic assembly equipment.
To sum up, the rotary positioning feeding mechanism provided by the embodiment has the following advantages: the blanking transfer driving mechanism 508 can be matched with the rotary positioning mechanism 4 to perform angle correction on each workpiece, so that each workpiece can be conveyed downstream at the same angle, and the completed angle correction mechanized operation can be performed, so that the labor cost is reduced, and the production efficiency is improved.
