[0023] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.
[0024] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "front", "back", "top", "bottom", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0025] like Figures 1 to 2As shown, a capacitor polishing device according to a preferred embodiment of the present invention includes a polishing bowl 1, a vibrator 2, a spring 3, a connecting bottom plate 4, a support frame 5, a vertical locking device 6, a winding device 7, a base 8 and a controller, wherein the controller is electrically connected to the vibrator 2, the vertical locking device 6 and the winding device 7 respectively; specifically, the vibrator 2 is a vibration motor, a plurality of springs 3 are located on the periphery of the vibrator 2, and the vibrator 2 is arranged at the center of the outer bottom wall of the polishing bowl 1; the winding device 7 is a winch;
[0026] The vibrator 2 is arranged on the outer bottom wall of the polishing bowl 1 and can drive the polishing bowl 1 to vibrate. The inner wall of the polishing bowl 1 is provided with an elastic rubber pad layer. The inner cavity of the polishing bowl 1 is used to place polishing abrasives and chip capacitors. Several springs 3 are provided and connected between the connecting base plate 4 and the bottom of the polishing bowl 1. The upper side wall of the polishing bowl 1 is provided with a rotating shaft 11 symmetrically provided on the left and right. The support frame 5 is provided on the base 8. The top of the support frame 5 is provided with a U-shaped groove 51 that rotates with the rotating shaft 11. The vertical locking device 6 is provided on the base 8. The vertical locking device 6 is used to lift the connecting base plate 4. The winding device 7 is provided on the base 8. The end of the traction rope 71 on the winding device 7 is connected to the upper front side wall of the polishing bowl 1 or the upper rear side wall of the polishing bowl 1;
[0027] like Figure 1 As shown, when the capacitive polishing device is polishing, the vertical locking device 6 lifts up the connecting base plate 4, the rotating shaft 11 is separated from the U-shaped groove 51, and the winding device 7 releases the traction rope 71 (so that the length of the traction rope 71 between the upper part of the polishing bowl 1 and the winding device 7 is increased), and the traction rope 71 is in a relaxed state, ensuring that the rotating shaft 11 does not interfere with the support frame 5 during the vibration of the polishing bowl 1, thereby ensuring the reliability of the polishing operation;
[0028] like Figure 2 As shown, when the capacitor polishing device is feeding or unloading, the vertical locking device 6 is reset, and the vertical locking device 6 is separated from the connecting base plate 4. Under the action of gravity, the rotating shaft 11 of the polishing bowl 1 falls back into the U-shaped groove 51. The rotating shaft 11 rotates and cooperates with the U-shaped groove 51. The winding device 7 winds up the traction rope 71 (so that the length of the traction rope 71 between the upper part of the polishing bowl 1 and the winding device 7 is shortened). The polishing bowl 1 is in a tilted state, and the rotating shaft 11 rotates and cooperates with the U-shaped groove 51 to ensure the stability of the tilting operation of the polishing bowl 1. When the capacitor polishing device is feeding, the opening of the polishing bowl 1 faces upward; when the capacitor polishing device is unloading, the opening of the polishing bowl 1 faces downward.
[0029] Exemplarily, the vertical locking device 6 includes a plurality of lifting cylinders, the cylinder bodies of the lifting cylinders are installed on the base 8, so that the vertical locking device 6 is stably connected to the base plate 4 for support. Preferably, a groove is provided on the connecting base plate 4 to cooperate with the end of the rod body of the lifting cylinder; specifically, when the capacitor polishing equipment is polishing, the rod body of the lifting cylinder extends out and lifts the connecting base plate 4; when the capacitor polishing equipment is feeding or unloading, the rod body of the lifting cylinder retracts and separates from the connecting base plate 4.
[0030] Exemplarily, a positioning cylinder 9 electrically connected to the controller is provided in the middle of the support frame 5. When the capacitor polishing device is feeding, the rod of the positioning cylinder 9 is extended, and the side wall of the polishing bowl 1 is abutted against the side wall of the rod of the positioning cylinder 9. The rod of the positioning cylinder 9 effectively supports the polishing bowl 1, improves the stability of the polishing bowl 1, and avoids excessive force on the traction rope 71 on the winding device 7; when the capacitor polishing device is polishing, the rod of the positioning cylinder 9 is retracted and separated from the polishing bowl 1.
[0031] Furthermore, the capacitor polishing equipment also includes a vertical position sensor electrically connected to the controller, the vertical position sensor includes a vertical position transmitting end arranged on the side wall of the polishing bowl 1 and a vertical position receiving end arranged on the support frame 5. When the vertical position receiving end detects the vertical position transmitting end, the polishing bowl 1 is in a vertical state. In this way, when the polishing bowl 1 is vertically in place, the vertical position sensor feeds back the information that the polishing bowl 1 is vertically in place to the controller, and the controller starts the vertical locking device 6 to lift the connecting base plate 4, starts the positioning cylinder 9 to extend the cylinder body of the positioning cylinder 9, and pauses the winding device 7 to ensure the accuracy of the position of the polishing bowl 1 during polishing.
[0032] Furthermore, the capacitor polishing equipment also includes a tilt-in-place sensor electrically connected to the controller, the tilt-in-place sensor includes a tilt-in-place transmitting end arranged on the side wall of the polishing bowl 1 and a tilt-in-place receiving end arranged on the support frame 5, when the tilt-in-place receiving end detects the tilt-in-place transmitting end, the polishing bowl 1 tilts to a preset tilt angle value; the tilt-in-place sensor feeds back the information that the polishing bowl 1 is tilted into place to the controller, and the controller pauses the winding device 7 to ensure that the position of the polishing bowl 1 is accurate when feeding.
[0033] Furthermore, the capacitive polishing equipment also includes a bowl in place sensor electrically connected to the controller, and the bowl in place sensor includes a bowl in place transmitting end arranged on the rotating shaft 11 and a bowl in place receiving end arranged in the U-shaped groove 51. When the bowl in place receiving end detects the bowl in place transmitting end, the rotating shaft 11 is placed in the U-shaped groove 51 to ensure that the rotating shaft 11 of the polishing bowl 1 and the U-shaped groove 51 of the support frame 5 are accurately in place. Then, the controller starts the winding device 7 to wind up the traction rope 71, thereby gradually tilting the polishing bowl 1.
[0034] Specifically, the elastic rubber pad layer is an 8mm thick polyurethane layer, which is wear-resistant and has a certain elasticity, effectively protecting the chip capacitor and extending the service life of the polishing bowl 1. Preferably, the polishing abrasive includes at least one of abrasives, polishing powder and sandpaper, which can be arbitrarily combined according to actual needs.
[0035] Exemplarily, the inner wall of the polishing bowl 1 is an arc surface, so that when the vibrator 2 vibrates, the chip capacitor and the polishing abrasive in the polishing bowl 1 continuously roll, reducing polishing dead angles.
[0036] In summary, the present invention cooperates with the vibrator 2 and the spring 3 to make the polishing bowl 1 suspended on the spring 3 repeatedly vibrate from the inside out, so that the chip capacitor and the polishing abrasive in the polishing bowl 1 roll, so as to achieve the purpose of polishing and grinding the chip capacitor end, making the chip capacitor metal end smoother and flatter, reducing metal nodules and metal impurities on the surface of the chip capacitor, and making the chip capacitor metal end tighter, reducing the voids in the metal end, and improving the qualified rate of the chip capacitor; the elastic rubber pad layer can reduce the damage caused by the polishing bowl 1 to the chip capacitor during the polishing process; by tilting the polishing bowl 1, the feeding equipment can feed the polishing abrasive and chip capacitor into the inner wall of the polishing bowl 1, and the winding device 7 releases the traction rope 71 to return the polishing bowl 1 from the tilted state to the vertical state, so that the polishing abrasive and chip capacitor slowly fall from the inner wall of the polishing bowl 1 to the bottom of the polishing bowl 1, avoiding damage to the chip capacitor and improving the degree of automation and work efficiency.

For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
