Description

Technical Field

[0001] The invention relates to the technical field of automatic glue dispensing, and in particular to a full-automatic continuous screw glue dispensing machine. Background Art

[0002] In the final assembly process of satellites, the dispensing of screws is a key step. The thread dispensing machine uses a rotating threaded shaft to squeeze glue out of the hose and moves the glue nozzle through pneumatic or electric drive to evenly apply the glue on the screw threads. The role of this layer of glue is to significantly reduce the loosening of the screws due to strong vibration and impact during the launch process. At the same time, it can evenly disperse stress and enhance the durability and fatigue resistance of the connection points. Through this fine dispensing technology, the structural components of the satellite can be more firmly combined together, improving the resistance to extreme temperature changes and micrometeoroid impacts in long-term space environments.

[0003] Although the existing screw dispensing equipment can realize automatic dispensing, in order to ensure the center alignment of the screws during the dispensing process, manual installation and disassembly are still required. For screws that require a large number of dispensing, manual installation operations are not only labor-intensive, but also lead to low dispensing efficiency. Summary of the invention

[0107] Working principle of the present invention:

[0108] First, the position of the dispensing head 800 is adjusted according to the diameter of the screw 400, and the knob 720 is turned to rotate the screw rod 710, and the screw rod 710 drives the threaded hole 731 to move forward or backward, so that the nozzle of the dispensing head 800 is close to the thread of the screw 400, so that the colloid sprayed by the dispensing head 800 can adhere to the thread of the screw 400. Fig.16 As shown, at this time, the motor 1 310 is started, and the motor shaft of the motor 1 310 drives the gear 1 320, the gear 2 330, and the large rotating disk 340 to rotate together in sequence. At this time, the clamping mechanism 500 is as shown in FIG. Fig.17 As shown, the electromagnet 523 is energized in the positive direction to attract the magnet 534, so that the drop hole 521 is in an unobstructed state. When the large turntable 340 rotates to the specified position (such as Figure 3 The clamping mechanism 500 is located at the position shown in the figure), the screw 400 is released by the screw feeder (existing technology), and when the screw 400 falls into the drop hole 521, the electromagnet 523 is energized in the reverse direction, and the magnet 534 is pushed to move toward the drop hole 521 by the magnetic repulsion force, and the limit hole 3 533 is threadedly connected with the screw rod 1 525, so that the screw rod 1 525 rotates, and the rotation of the screw rod 1 525 drives the moving clamp 530 on the other side to move toward the drop hole 521, and the moving clamps 530 on both sides are kept moving the same distance, so that when the clamping surface 531 finally clamps the screw 400, the center of the screw 400 can coincide with the center of the drop hole 521, and the mark Figure 3 The clamping mechanism 500 is located at position 1, and clockwise positions 2, 3, and 4 (positions 1, 2, 3, and 4 are fixed, and the clamping mechanism 500 is rotating). Repeat the above process. When the multiple screws 400 move to positions 2 and 3 respectively, the motor 3 620 is started in the positive direction, so that the motor shaft of the motor 3 620 drives the screw 2 630 to rotate. The rotation of the screw 2 630 causes the connecting frame 650 to move upward. Since the circular hole 3 653 is connected to the bearing 661, the motor 4 660 The dispensing head 800 moves upward with the connecting frame 650, and the motor 4 660 is started at the same time. The motor shaft of the motor 4 660 is fixedly connected to the limiting cylinder 671. The motor 4 660 drives the moving frame 670, the dispensing head 800, and the screw limiting group 900 to rotate together, so that the 2nd and 3rd screws 400 can be dispensed with glue by the dispensing head 800 at the same time during the rotation process. At the same time, when the dispensing head 800 dispenses glue, the top surface 911 of the screw limiting group 900 abuts against the lower end surface of the screw 400 (such as Fig.18As shown), during the continuous upward movement of the screw limiting group 900, the top head 910 is still pressed against the screw 400 under the elastic force of the spring 920, and the screw 400 is limited to prevent the screw 400 from deviating from the center during the dispensing process. After the dispensing head 800 rotates a certain distance and the screw 400 has been glued, the screw 400 continues to rotate to the next position. At this time, the motor three 620 and the motor four 660 are started in reverse, so that the dispensing head 800 moves downward and rotates back to the original position in the opposite direction. When new screws 400 appear at positions 2 and 3, the above process is repeated to realize the uninterrupted dispensing process of the screw 400. When the screw 400 after the dispensing is completed reaches the 4th position, the moving clamp 530 controlled by the electromagnet 523 opens and falls below the drop hole 521, so that the screw 400 is detached.
