Description

Technical Field

[0001] The present invention relates to the technical field of capacitor production, and in particular to a special device for automatic series connection of capacitors. Background Art

[0002] During the production process of capacitors, aging tests need to be performed on them. The capacitors need to be inserted into the capacitor racks first, and then the capacitor racks filled with capacitors are removed and placed in special equipment for capacitor aging. At present, when capacitors are connected in series, the capacitors are generally placed on top of the conveyor belt. After the conveyor belt transports them to the designated position, the robot grabs them and places them on the positioning mechanism so that the positive and negative poles on the capacitors are in the required position. Then, the flipping mechanism is used to flip them 180 degrees and place them on the platform. Then, the grabbing mechanism is used again to grab the capacitors and plug them into the capacitor racks. During the above operation, there are many overall processes, and the capacitor racks can only be plugged in and connected in series after they are moved to the designated position. The two are driven independently, which may cause certain position deviations. To this end, we have designed a special device for automatic capacitor connection. Summary of the invention

When the capacitor contacts the conveyor belt, it will move along the conveyor belt toward the centralized track, so that the capacitor can be arranged in sequence in the centralized track, where the width of the centralized track is suitable for one capacitor.

[0006] Furthermore, the positioning rotating table comprises an electric rotating table fixed on the top of the frame, a fixed card plate is installed on the table top of the electric rotating table, and a fixed card slot matching the outer diameter of the capacitor is opened on the fixed card plate; A rubber pad is also provided in the fixed card slot, and the capacitor placed in the fixed card slot can be pressed by the rubber pad to prevent its position from shifting during rotation. The capacitor at the left end of the centralized track is grabbed by the mechanical grabber and placed in the fixed card slot. After that, the CCD detection and positioning module will observe the position of the positive and negative electrodes on the capacitor, and the electric rotating table will rotate it, so that the positive and negative electrodes of the deflected capacitor are in the required position. When the capacitor is subsequently plugged into the top of the capacitor rack, the positive and negative poles of the capacitor can be accurately plugged into the positive and negative poles of the capacitor rack. The CCD detection and positioning module is a CCD vision module.

The setting of the lifting notch facilitates the rotation of the linkage rod and does not interfere with its deflection.

When the lifting part moves upward, the flipping part will move upward accordingly.

After the reciprocating slider moves forward by one unit, it is disengaged from the lifting block, and the positioning column can abut the lower surface of the forward plate until the forward plate is in the desired position.

By arranging a lifting member on the translation member, and arranging a flip member and a clamping cylinder on the lifting member, the clamping cylinder will flip 180 degrees during the process of clamping the capacitor and translating, and then it can be smoothly placed on the capacitor rack in series. Compared with the existing flipping and then clamping and stringing action, it saves one beat and improves the efficiency of stringing; 2. Two groups of translation parts, lifting parts, flip parts and clamping cylinders are set synchronously. When one group of mechanisms is clamping and taking materials, the other group can perform serial operation. The two groups of mechanisms are operated alternately, which improves the efficiency of serial operation. 3. By setting up a rack conveying mechanism, and connecting the driving member in the rack conveying mechanism with the translation member in the series arrangement mechanism through a driving rack, when the translation member approaches the capacitor rack, the intermittent conveying member can retreat a certain distance. When the series arrangement of capacitors is completed and the capacitor rack is away from the capacitor rack, the entire capacitor rack can move forward one unit, so that the vacant position of the capacitor rack is directly below the capacitor to be series-arranged, which is convenient for subsequent series arrangement and improves the accuracy of series arrangement.

When the reciprocating slider 732 moves backward, the downward pressing block 755 can be pressed on the top of the lifting block 752, thereby causing the lifting block 752 and the positioning column 751 to move downward, and the positioning column 751 releases the restriction on the positioning slot 725, and the forward plate 721 can The positioning column 751 is inserted into the positioning groove 725, thereby completing the positioning of the capacitor rack 8 so that it will not be offset in position and can be accurately placed directly below the capacitor to be plugged in.

[0026] Working principle: In actual use, multiple capacitors are placed above the conveyor belt 11. The capacitors will move to the left on the conveyor belt 11. When they touch the two sets of transmission belts 13, they will move along the transmission belts 13 to the middle of the two sets of transmission belts, and then be arranged and distributed in sequence in the centralized track 2. Then the mechanical gripper 4 will grab a capacitor and place it in the fixed card slot, and then the CCD detection and positioning module 3 will observe the position of the positive and negative electrodes on the capacitor, and the electric rotating table will rotate it, so that the positive and negative electrodes of the deflected capacitor are in the required position; Then the clamping cylinder 66 moves downward together with the lifting member 64. After moving to the desired position, the capacitor clamping plate 661 of the clamping cylinder 66 will clamp the capacitor and move up again under the action of the lifting member 64. At this time, the rolling wheel 673 of the flip member 67 is placed in the lifting track 2 614, and the rolling wheel 673 of the other group of flip members 67 is placed in the corresponding lifting track 1 612. After rising to the desired position, the driving motor makes the moving screw 62 rotate, and the two groups of translation members 63 will move forward as a whole. When the translation member 63 moves forward, the rolling wheel 673 will also move along the flip track 613 and the translation track 611. When the rolling wheel 673 moves on one of the slopes in the flip track 613, the flip disk 671 will deflect with its axis as the rotation axis. When the rolling wheel 673 is at the highest point, the flip disk 671 rotates ninety degrees. Then, when the rolling wheel 673 moves along another slope, the flip disk 671 rotates ninety degrees again, so that the entire flip disk 671 rotates one hundred and eighty degrees. The capacitor clamped on the capacitor clamping plate 661 will be flipped one hundred and eighty degrees, so that the positive and negative ends face downward, and then continue to move along the translation track 611. When it moves to the top of the corresponding capacitor rack 8, the rolling wheel 673 in the flip member 67 is in the corresponding lifting track 1 612, and the other group of translation members 63 is in the middle, and the rolling wheel 673 in this group is in the lifting track 2 614, and then it moves down again, and the two groups of clamping cylinders 66 respectively connect the capacitors in series and clamp the capacitors, and then rise again - move in the opposite direction - descend - clamp the capacitors, connect the capacitors in series, and so on alternately reciprocate; When the translation member 63 is moving, the driving rack 65 on the translation plate 631 will mesh with the driving gear 741 and make it rotate. When the translation plate 631 approaches the driving gear 741, the driving gear 741 rotates counterclockwise. When the translation plate 631 is away from the moving gear, the driving gear 741 rotates clockwise. When the driving gear 741 rotates counterclockwise, the reciprocating rack 731 will move backward by a unit distance. At this time, the position of the entire capacitor rack 8 will not change. After the capacitor is plugged into the top of the capacitor rack 8, the translation plate 631 moves toward the middle again. At this time, the reciprocating rack 731 moves forward under the action of the driving rack 65, and the entire capacitor rack 8 moves forward by a unit distance. When the reciprocating rack 731 moves backward, the pressing block 755 can be pressed against the lifting block 752, so that the lifting block 752 and the positioning column 751 move downward, and the positioning column 751 releases the restriction on the positioning slot 725, so that the forward plate 721 can move normally, and after the reciprocating slider 732 moves forward by one unit, it is separated from the contact with the lifting block 752, and the positioning column 751 can abut against the lower surface of the forward plate 721 until the forward plate 721 is in the desired position. At this time, the positioning column 751 is inserted into the positioning slot 725, thereby completing the positioning of the capacitor rack 8, so that it will not be offset in position and can be accurately placed directly below the capacitor to be inserted; By arranging a lifting member 64 on the translation member 63, and arranging a flip member 67 and a clamping cylinder 66 on the lifting member 64, the clamping cylinder 66 will flip 180 degrees during the process of clamping the capacitor and translating, and then the capacitor can be smoothly placed on the capacitor rack 8 in series. Compared with the existing flipping and then clamping and placing in series action, it saves one beat and improves the efficiency of placing in series. Two groups of translation parts 63, lifting parts 64, flipping parts 67 and clamping cylinders 66 are synchronously arranged. When one group of mechanisms is clamping and taking materials, the other group can perform serial operation. The two groups of mechanisms are operated alternately, which improves the efficiency of serial operation. By setting up a rack conveying mechanism 7, and connecting the driving member 74 in the rack conveying mechanism 7 to the translation member 63 in the string arrangement mechanism 6 through the driving rack 65, when the translation member 63 is close to the capacitor rack 8, the intermittent conveying member 73 can retreat a certain distance, and when the capacitors are away from the capacitor rack 8 after the string arrangement is completed, the entire capacitor rack 8 can move forward one unit, so that the vacant position of the capacitor rack 8 is directly below the capacitor to be stringed, which is convenient for subsequent stringing and improves the accuracy of stringing.
