Detailed Description
The present invention will be described in detail with reference to examples, which are only preferred embodiments of the present invention and are not intended to limit the present invention.
As shown in fig. 1 and 2, the present embodiment provides a capacitor nail roll nail deviation detection method, which includes the following steps: in the process of winding the capacitor core package, a lead 2 is nailed on an electrode foil 1, then whether the nailed lead 2 is in a vertical state with the long edge of the electrode foil 1 or not is detected, if the nailed lead 2 is detected to be in a non-vertical state, the machine is stopped by alarming, and if the nailed lead 2 is detected to be in a vertical state, the winding action is not alarmed and continues. Specifically, the nail deviation detecting device detects whether the nailed lead 2 is perpendicular to the long side of the electrode foil 1.
Further, the nail deviation detection device comprises a conducting strip 4 with a slot 5 and a short circuit detection circuit 8, wherein the nail machine table 3 and the conducting strip 4 bearing the electrode foil 1 are respectively used as opposite electrodes of the short circuit detection circuit 8, preferably, the nail machine table 3 is electrically connected with one end of the short circuit detection circuit 8 through a lead wire and can be used as a negative electrode, and the conducting strip 4 is electrically connected with the other end of the short circuit detection circuit 8 through a lead wire and can be used as a positive electrode. The notch 5 is adapted to the lead 2, and it is understood that the width dimension of the notch 5 is equal to or slightly larger than the width dimension of the lead 2.
In the nailing process of the lead 2, the following steps are mainly adopted: electrode foil 1 punched hole → lead wire 2 is straightened and nailed and stretched through the punched hole of electrode foil 1 → lead wire 2 is fixedly connected to electrode foil 1 by crimping or riveting with crimping mechanism 7. In the last two steps, the lead 2 is pre-positioned only by stretching the nail hole, so that the lead 2 has the possibility of deviation in the nailing process, and the lead 2 has the possibility of deviation after the nailing is finished. When normal nailing is carried out, the lead 2 and the long side of the electrode foil 1 are in a 90-degree vertical state, when nail deviation is generated, the lead 2 deviates along with the lead, namely the lead 2 and the long side of the electrode foil 1 are in a non-90-degree vertical state but form a certain included angle, and because the deviation amount is small, slight deviation of the lead 2 is not concerned in the industry at present, so even if a core package with deviation nail exists in the nailing process, a nailing and rolling machine cannot reject the core package as a defective product, but a great deal of investigation tests show that when the nail deviation of the lead 2 exists in the nailing process, after subsequent formation, impregnation, assembly and aging, the capacitor with deviation of the lead 2 basically generates short circuit defects, and even if the capacitor flows to a client side to cause short circuit under the condition that the aging process is not rejected, the influence is larger.
In order to solve the technical problem, the nail-coiling machine is additionally provided with a nail deviation detection device by the inventor, the principle that a short circuit is generated when a positive electrode and a negative electrode are contacted together is utilized, as shown in fig. 6, a nail-coiling machine table 3 and a conducting strip 4 of the nail deviation detection device are used as opposite electrodes, a notch 5 is formed in the conducting strip 4 and matched with a lead 2, the conducting strip 4 moves towards one side of the lead 2 during detection, when the lead 2 is contacted with the opposite side of a left nail and a right nail deviation (the lead 2 after the nail-coiling machine is contacted with a long edge of an electrode foil 1 in a non-vertical state), the opposite electrode is contacted and conducted, a short circuit is caused, and then an alarm sound is sent out, meanwhile, the nail-coiling machine stops running, and the nail-coiling machine can normally run until the problem is solved. When the lead 2 is not nailed or deviated (the lead 2 after being nailed and the long edge of the electrode foil 1 are in a vertical state), the lead 2 is completely positioned in the notch 5 and does not touch the conducting strip 4, so that the opposite electrode is not contacted and conducted, short circuit and alarm can not be caused, and meanwhile, the roll nailing machine continues to operate normally. The invention can ensure that 100% of defective products with deviated nails of the lead 2 cannot flow to the next working procedure, reduce the occurrence of poor short circuit caused by aging, prevent low cost and improve the yield and reliability of products. The inventor also finds that although the lead wire after the nail connection can be detected by the visual detection system and is in a vertical state with the long edge of the electrode foil, the nailing machine is integrated with the nail connection equipment and the winding equipment, the whole nailing machine is complex in structure and small in available space of a detection area, and the product size is small, so that the visual false detection probability of the visual detection system is high, the manufacturing cost is high, the nailing machine needs to be greatly modified, and the practicability is low.
In some embodiments, the short circuit detection circuit 8 is connected to a stapler control circuit board 9. In some embodiments, the short circuit detection circuit 8 is integrated on the control circuit board 9 of the stapler. It should be noted that the short circuit detection circuit 8 is not improved, and when the lead 2 positioned on the nailing machine table 3 touches the conductive sheet 4, the short circuit detection circuit 8 can identify a short circuit and transmit a short circuit signal to the control circuit board 9 of the nailing machine, so that the nailing machine can alarm and stop.
In some embodiments, the conductive sheet 4 of the nail deviation detecting device is disposed on the crimping mechanism 7, that is, the conductive sheet 4 of the nail deviation detecting device is mounted on the crimping mechanism 7 through the connecting block 6 in an insulated manner, and moves along with the movement of the crimping mechanism 7. In some embodiments, the conductive sheet 4 of the nail deviation detecting device is insulated and connected to the crimping mechanism 7 through a driving mechanism (not shown), and the driving mechanism is connected to the control circuit board 9 of the nailing machine, so that the conductive sheet 4 of the nail deviation detecting device can be driven to move towards one side of the lead 2 by the driving mechanism after the nailing is completed. In other embodiments, the conductive plate 4 of the nail deviation detecting device can be directly connected with the driving mechanism, and the driving mechanism is independent of the crimping mechanism 7.

Further, the nail deviation detection device comprises a conducting strip 4 with a notch 5 and a short circuit detection circuit 8, wherein the nail machine table 3 and the conducting strip 4 bearing the electrode foil 1 are respectively used as opposite electrodes of the short circuit detection circuit 8, preferably, the nail machine table 3 is electrically connected with one end of the short circuit detection circuit 8 through a lead and can be used as a negative electrode, and the conducting strip 4 is electrically connected with the other end of the short circuit detection circuit 8 through a lead and can be used as a positive electrode. The notch 5 is adapted to the lead 2, and it is understood that the width dimension of the notch 5 is equal to or slightly larger than the width dimension of the lead 2.
It should be noted that the nailing machine 3 may also be a positive electrode, and the conductive sheet 4 is a negative electrode.
Further, the conducting strip 4 moves up and down relative to the nailing machine table 3 outside the nailing machine table 3. In some embodiments, the conductive plate 4 of the nail deviation detecting device is connected to the crimping mechanism 7 through the connecting block 6 in an insulated manner, i.e. the conductive plate 4 of the nail deviation detecting device is mounted on the crimping mechanism 7 and moves along with the movement of the crimping mechanism 7. In some embodiments, the conductive sheet 4 of the nail deviation detecting device is connected to the crimping mechanism 7 through a driving mechanism, and the driving mechanism is connected to the control circuit board 9 of the nailing machine, so that after the nail is completed, the conductive sheet 4 of the nail deviation detecting device is driven by the driving mechanism to move towards one side of the lead 2. In other embodiments, the conductive plate 4 of the nail deflection detecting device can be directly connected with the driving mechanism through the connecting block 6, and the driving mechanism is independent of the crimping mechanism 7.
Further, in some embodiments, the conductive sheet 4 is provided with a plurality of notches 5 along the long side direction of the electrode foil 1, as shown in fig. 4, the width dimensions of each notch 5 are different, and the notches can be respectively matched with the leads 2 with different widths, so that the universality is satisfied, and the conductive sheets 4 with various specifications do not need to be modified and designed.

In some embodiments, the short circuit detection circuit 8 is connected to a stapler control circuit board 9. In some embodiments, the short circuit detection circuit 8 is integrated on the control circuit board 9 of the stapler. It should be noted that the short circuit detection circuit 8 is not improved, and when the lead 2 positioned on the nailing machine table 3 touches the conductive sheet 4, the short circuit detection circuit 8 can identify a short circuit and transmit a short circuit signal to the control circuit board 9 of the nailing machine, so that the nailing machine can alarm and stop.
The capacitor according to the present invention may be an aluminum electrolytic capacitor, a super capacitor, or a capacitive aluminum battery. When the core package of the capacitor is formed by winding the electrode foil 1 with the lead 2 nailed, which is inserted into the electrolytic paper, the nail deviation detection can be carried out by adopting the detection method of the invention.
