Description

Technical Field

[0001] The invention relates to the technical field of automatic conveying equipment, in particular to a special automatic conveying device for capacitors and a working process. Background Art

[0002] Capacitors are components that store electrical charge and electrical energy (potential energy). A conductor surrounded by another conductor, or where all the electric field lines emitted by one conductor terminate in the conductor system of another conductor, is called a capacitor.

[0003] During the processing of capacitors, one of the key process steps is painting. In the prior art, manual or power-assisted balance arms are usually used to transport and paint capacitors, and the overall work efficiency is low and cannot meet the use requirements.

[0004] At present, in order to improve work efficiency, especially for larger capacitors (greater than 150kg), a combination of robots and suction cups is used to automatically load and unload materials. Since the robot's polar axis has a certain angular acceleration when moving, if the surface of the capacitor is uneven, it is very easy to fall, which poses a great safety hazard during the work process. In addition, this method cannot achieve automated production. Summary of the invention

[0005] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a capacitor-specific automatic conveying device and work flow, which can eliminate safety hazards, greatly improve work efficiency, and meet usage requirements.

[0015] The second suspension rod is a telescopic rod.

[0067] The workpiece is a capacitor 11 , and symmetrical ears 1102 are provided on both sides of the capacitor 11 . The cross section of the ears 1102 is a “┗┛” structure. An oblong hole 1103 is opened in the middle of the ears 1102 , and symmetrical circular holes 1101 are opened on both sides of the ears 1102 .

[0068] The loading platforms are fixed on the ground, and there are three of them, namely, the NG piece loading platform 3, the lower piece loading platform 4 and the upper piece loading platform 5.

[0069] The workflow of the capacitor-specific automatic conveying device of this embodiment includes the following steps:

[0070] Step 1: Preparation;

[0071] Put the capacitor 11 to be processed in the stage;

[0072] Step 2: Grab the work;

[0073] The servo mobile trolley 6 works, moves to the vicinity of the capacitor 11 to be grasped, and then uses the lifting mechanism 7 to adjust the height position, and uses the displacement grasping mechanism 8 to adjust the width position, and grasps the capacitor 11 to be processed after adjustment;

[0074] Step 3: Lifting work;

[0075] The servo mobile trolley 6 continues to work, moves the capacitor 11 that has been grabbed to the vicinity of the hanger 10, and then places the capacitor 11 on the hanger 10;

[0076] Step 4: The trolley returns to work;

[0078] Step 5: The workpiece returns to work;

[0079] The capacitor 11 that has completed the work on the accumulation line 9 is grabbed again by the displacement grabbing mechanism 8, and then placed back on the designated loading platform by the servo mobile car 6.

[0080] In actual working process:

[0081] First, the capacitor 11 to be processed is placed on the upper workpiece loading platform 5, and the motor 602 of the servo mobile trolley 6 is started, the gear 603 rotates, and the cooperation between the gear 603 and the servo slide 2 drives the entire servo mobile trolley 6 to slide to the position of the capacitor 11. Then the lifting mechanism 7 works, and the position of the lifting plate 701 is adjusted by the lifting cylinder 703, thereby adjusting the height position of the entire displacement grasping mechanism 8. After the height position is adjusted, the position of the fixing seat 804 is adjusted by the adjusting cylinder 806, thereby adjusting the width between the two sliders 807, and the width matches the width of the capacitor 11. Then, the motor 802 works to drive the chain transmission mechanism 803 to work and drive the screw rod 808 to rotate, thereby adjusting the relative position of a pair of sliders 807 on the screw rod 808, thereby adjusting the action of the clamp 809, and the clamp 809 is extended into the circular hole 1101 of the ear 1102 by the fixed head 810, that is, the grasping work is realized.

[0082] After the grabbing is completed, the lifting mechanism 7 rises, and then the servo mobile trolley 6 is started to transport the already grabbed capacitor 11 to the direction of the hanger 10, until the oblong hole 1103 on the lifting ear 1102 of the capacitor 11 is placed in the chuck 1006 of the hanger 10. At this time, the hanger 10 has successfully lifted the capacitor 11, the screw rod 808 rotates in the opposite direction, the clamping claw 809 is released from the circular hole 1101, and the displacement grabbing mechanism 8 withdraws, and it is transported back by the servo mobile trolley 6 to grab the next capacitor 11 to be processed; and the capacitor 11 currently on the hanger 10 is transported to the next process (usually painting) through the accumulation line 9. When the work is completed in the next process, the capacitor 11 is returned to the position of the accumulation line 9 by the original route, and then the displacement grabbing mechanism 8 is continued to be used to grab the capacitor 11 that has completed the next process and place it on the next piece loading platform 4. If the grabbed product is a defective product, it is placed on the NG piece loading platform 3, and the cycle can be repeated.

[0083] The design of the lifting lug 1102 described in the present invention can be used in both grabbing and hanging operations, and has a compact structure and reliable connection.

[0084] A cam mechanism (not shown in the figure), a rack and pinion mechanism (not shown in the figure) or a four-bar linkage mechanism (not shown in the figure) can also be installed inside the No. 2 suspension rod 1004 in the sling 10 described in the present invention, so that the No. 2 suspension rod 1004 becomes an adjustable suspension rod structure, which can conveniently adjust the position of the clamping rods 1005 on both sides, thereby adjusting the width of the two clamps 1006, which can conveniently adapt to the width requirements of different products and work flexibly and reliably.

[0085] The regulating cylinder 806 described in the present invention can also be replaced by a servo motor to facilitate stepless adjustment of the width requirements and meet the width requirements of capacitors 11 of various models.

[0086] The base plate 1 and the loading platform of the present invention are directly fixed on the ground, and the height of the sling 10 is not very high, so that the height of the capacitor 11 being lifted can be reduced and the shaking of the capacitor 11 can also be reduced.

[0087] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
