Description

Technical Field

[0001] The utility model belongs to the field of capacitor chamfering, and in particular relates to a chamfering device for a pulse capacitor. Background Art

[0002] In the process of making capacitors, chamfering before sintering can avoid excessive accumulated stress at the chip corners during sintering, which may even cause cracks in the chip during sintering. When silvering the chip without chamfering, the silver paste cannot completely cover the end, leaving the ceramic body partially exposed, causing the plating liquid to penetrate during electroplating, affecting the DF value and IR value of the capacitor during testing.

[0003] At present, pulse capacitors need to be chamfered on their edges after sintering. The current mode of chamfering takes up to 72-120 hours. Since multiple products are placed in a row, they are prone to collide with each other, which can easily cause the chamfered products to crack, which needs further improvement. Utility Model Content

[0008] Furthermore, the locking member includes a locking screw hole extending downwardly from the upper locking block, a positioning hole arranged on the upper pressure plate opposite to the locking screw hole, and a locking bolt whose lower end cooperates with the locking screw hole and can be embedded in the positioning hole.

[0009] Furthermore, the limiting member includes a limiting hole arranged on the lower pressing plate and opposite to the lower locking block, and a limiting elastic buckle arranged on the lower locking block and capable of being embedded in the limiting hole.

[0010] Furthermore, the first chamfered tank includes a first chamfered tank body, a first chamfered cavity arranged in the first chamfered tank body for placing the pulse capacitor, and a plurality of first fixing grooves circumferentially distributed on the outer periphery of the first chamfered tank body for embedding a relative fixing plate.

[0011] Furthermore, a mounting groove extending upward for mounting a lower pressure plate is formed at the bottom of the first chamfered tank body.

[0026] The fixing mechanism 3 includes an upper pressing plate 31 arranged on the top of the sealing plate 5, a lower pressing plate 32 arranged at the bottom of the first chamfered tank 1, a plurality of fixing plates 33 circumferentially distributed on the outer periphery of the plurality of second chamfered tanks 1 and the first chamfered tank 2, an upper locking block 34 and a lower locking block 35 respectively arranged at the upper and lower ends of the fixing plate 33 and contacting the upper pressing plate 31 and the lower pressing plate 32, a locking member 36 arranged between the upper locking block 34 and the upper pressing plate 31, and a limiting member 37 arranged between the lower locking block 35 and the lower pressing plate 32; specifically, the locking member 36 includes a locking screw hole 361 arranged on the upper locking block 34 and extending downward , a positioning hole 362 is arranged on the upper pressure plate 31 opposite to the locking screw hole 361, and a locking bolt 363, the lower end of which cooperates with the locking screw hole 361 and can be embedded in the positioning hole 362; further, the limiting member 37 includes a limiting hole 371 arranged on the lower pressure plate 32 opposite to the lower locking block 35, and a limiting elastic buckle 372 arranged on the lower locking block 35 and can be embedded in the limiting hole 371. Through the cooperation between the limiting elastic buckle 372 and the limiting hole 371, the position of the fixed plate 33 is initially positioned, and at the same time, it can prevent the fixed plate 33 from falling off during the rolling process of the chamfering device, thereby affecting the chamfering process of the pulse capacitor.

The multiple second fixing grooves 23 and the first fixing grooves 13 are distributed, and the limiting elastic buckle 372 is embedded in the relative limiting hole 371 to realize the initial positioning of the fixing plate 33, and then the locking bolt 363 cooperates with the locking hole 361 to make its lower end embedded in the positioning hole 361 to complete the fixation of the multiple second chamfered tanks 2 and the first chamfered tank 1; specifically, the upper pressure plate 31 and the lower pressure plate 32 are made of stainless steel, because the first chamfered tank 1 and the second chamfered tank 2 are made of nylon. In order to ensure the fixation of the first chamfered tank 1 and the multiple second chamfered tanks 2, it is necessary to set the upper pressure plate 31 and the lower pressure plate 32 of stainless steel at the upper and lower ends respectively, so that the locking bolt 363 can be tightened to ensure the use of the first chamfered tank 1 and the multiple second chamfered tanks 2.

The sealing groove 61 and the sealing ring 62 cooperate with each other to ensure the sealing of the chamfering process in the first chamfered tank 1 and the second chamfered tank 2, thereby ensuring the chamfering effect of the pulse capacitor.

[0030] The working principle of this application specifically includes the following steps:

[0031] Step 1: Place the pulse capacitor into the first chamfered tank 1 or the second chamfered tank 2, then add water and polishing balls in sequence, then insert the sealing ring 62 into the sealing groove 61, and then stack multiple second chamfered tanks 2 in sequence according to the equipment requirements;

[0032] Step 2: The fixing plate 33 is embedded in the plurality of second fixing grooves 23 and the first fixing groove 21 distributed along the same longitudinal line, and the limiting elastic buckle 372 is embedded in the relative limiting hole 371 to achieve the initial positioning of the fixing plate 33, and then the locking bolt 363 cooperates with the locking hole 361 to make its lower end embed into the positioning hole 362, thereby completing the fixing of the plurality of second chamfered cans 2 and the first chamfered can 1;

[0033] Step 3: Rotate the chamfering device that has been locked and fixed by 90 degrees and place it flat on the chamfering machine for rolling chamfering.

[0034] The present application limits the structure of the chamfering device and sequentially arranges a first chamfering tank 1 and multiple second chamfering tanks 2 to place single pulse capacitors respectively. While ensuring the chamfering efficiency, it can also effectively reduce the occurrence of cracks in the pulse capacitors after chamfering. The introduction of the positioning mechanism 4 can improve the stacking efficiency of the multiple second chamfering tanks 2, and the introduction of the sealing mechanism 6 can ensure the sealing of the chamfering device, thereby ensuring the chamfering effect of the pulse capacitor.
