Description

Technical Field

[0001] The present invention relates to the technical field of tantalum capacitor processing, and specifically to a sintering furnace for tantalum capacitor processing. Background Technique

[0002] The full name of the tantalum capacitor is tantalum electrolytic capacitor, which also belongs to a kind of electrolytic capacitor. It uses metallic tantalum as the dielectric, unlike ordinary electrolytic capacitors that use electrolyte. Tantalum capacitors do not need to use capacitor paper coated with aluminum film for firing like ordinary electrolytic capacitors. It has almost no inductance itself, but this also limits its capacitance. In addition, there is no electrolyte inside the tantalum capacitor, so it is very suitable for working at high temperatures. The characteristics of tantalum capacitors are long life, high temperature resistance, high accuracy, and excellent filtering and high-frequency rectification performance. However, their capacitance is relatively small, and their voltage and current resistance capabilities are weak. They are applied in places where large-capacity filtering is required. For example, tantalum capacitors can be seen near the CPU socket, often used in combination with ceramic capacitors and electrolytic capacitors or applied in places where the voltage and current are not large.

[0003] During the processing and preparation of tantalum capacitors, it is necessary to pre-burn the tantalum capacitor raw materials, that is, to remove the binder in the pressed tantalum block; sintering is to sinter the tantalum block that has been debound into a micro-porous body with a certain mechanical strength. In the sintering process, only the contacting parts between particles are fused together. However, if the sintering temperature is too high, it will lead to too much fusion between particles, resulting in a reduction in surface area; there are strict control requirements for parameters such as the vacuum degree, starting temperature, heating, heat preservation, cooling, furnace discharging, and furnace transfer time of the furnace for dewaxing and sintering.

[0004] Traditional sintering furnaces for tantalum capacitor processing still have some problems in specific use: manual loading and unloading are required, the steps are relatively cumbersome, and the temperature is relatively high during unloading, which is likely to cause damage to the staff and there are certain safety hazards.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-7, the present invention provides a technical solution: a sintering furnace for tantalum capacitor processing, including a support frame 1, a sintering furnace frame 2 is fixedly installed in the middle of the support frame 1, an auxiliary plate 3 is fixedly installed on the outer top of the sintering furnace frame 2, a fixed ventilation mechanism 4 is arranged in the middle of the sintering furnace frame 2, a plurality of placing frames 11 are stacked and placed outside the fixed ventilation mechanism 4, a sintering part 5 is arranged in the middle of the sintering furnace frame 2, a feeding component 6 is fixedly installed on the top end of the auxiliary plate 3, a sealing ring base 7 is fixedly installed at the bottom end of the sintering furnace frame 2, a first clamping mechanism 8 is fixedly installed on the inner top of the sintering furnace frame 2, a second clamping mechanism 9 is fixedly installed on the inner bottom of the sintering furnace frame 2, and an observation window 10 is arranged on one side of the sintering furnace frame 2 close to the sintering part 5.

[0030] The fixed ventilation mechanism 4 includes a fixed ventilation guide cylinder 41, a fixed ventilation inner cylinder 42 is slidably clamped at the inner bottom of the fixed ventilation guide cylinder 41, two symmetrically distributed positioning frames 43 are slidably clamped outside the fixed ventilation inner cylinder 42, the opposite sides of the two positioning frames 43 extend into the fixed ventilation guide cylinder 41, the opposite parts of the positioning frames 43 are both wedge-shaped structures, positioning chutes 411 corresponding to the positioning frames 43 are opened on the fixed ventilation guide cylinder 41, and the positioning frames 43 are slidably clamped in the corresponding positioning chutes 411. The opposite sides of the two positioning frames 43 extend out of the outside of the fixed ventilation guide cylinder 41. Driving the fixed ventilation inner cylinder 42 to lift drives the two positioning frames 43 on both sides to lift;

[0031] Wedge-shaped driving blocks 44 are arranged on the opposite sides of the two positioning frames 43. The upper surface of the wedge-shaped driving block 44 contacts the inner upper wall of the fixed ventilation inner cylinder 42 to limit the top end of the wedge-shaped driving block 44. The wedge-shaped driving block 44 is an inverted trapezoidal structure. Ball bearings 431 are rotatably clamped on the opposite sides of the two positioning frames 43. The ball bearings 431 contact the outside of the wedge-shaped driving block 44. By the wedge-shaped driving block 44 pressing against the two positioning frames 43, the two sides are always kept in a relatively separated state, so that the opposite sides of the two positioning frames 43 both extend out of the outside of the fixed ventilation guide cylinder 41. Fixed installation frames 45 are fixedly installed at the opposite ends of the two positioning frames 43. A guide shaft 451 is movably inserted in the middle of the insertion frame 45. The guide shaft 451 is fixedly installed on the inner wall of the fixed ventilation inner cylinder 42. First springs 452 are movably sleeved on the outside of the guide shaft 451 between the insertion frame 45 and the inner wall of the fixed ventilation inner cylinder 42. The two ends of the first spring 452 are respectively fixedly connected to the insertion frame 45 and the inner wall of the fixed ventilation inner cylinder 42. In the initial state, the first spring 452 is in a compressed state. When the wedge-shaped driving block 44 is driven to move downwards, the ball bearings 431 roll on the wedge-shaped driving block 44, and the first spring 452 slowly expands, driving the two positioning frames 43 to move towards each other and be received in the fixed ventilation guide cylinder 41.

[0032] A sliding shaft 46 is fixedly installed in the middle of the bottom end of the wedge-shaped driving block 44. The bottom of the sliding shaft 46 movably penetrates through the middle of the bottom end of the fixed drainage inner cylinder 42 to improve the stability of the lifting of the wedge-shaped driving block 44. A second spring 461 is fixedly installed between the bottom end of the wedge-shaped driving block 44 and the inner lower wall of the fixed drainage inner cylinder 42. The second spring 461 is sleeved on the outside of the sliding shaft 46. A connecting seat 462 is fixedly installed at the bottom end of the sliding shaft 46. In the initial state, the second spring 461 is in a normal state. The second spring 461 always abuts against the wedge-shaped driving block 44 to prevent the wedge-shaped driving block 44 from moving downward. When driving the connecting seat 462 to drive the sliding shaft 46 and the wedge-shaped driving block 44 to move downward, the second spring 461 contracts.

[0033] A fixed drainage middle cylinder 47 is fixedly installed at the bottom end of the fixed drainage guide cylinder 41. A multi-stage telescopic rod 471 is fixedly installed in the fixed drainage middle cylinder 47. The driving end of the multi-stage telescopic rod 471 extends into the fixed drainage guide cylinder 41 and is fixedly installed with the connecting seat 462. Controlling and activating the multi-stage telescopic rod 471 drives the connecting seat 462, the sliding shaft 46, the wedge-shaped driving block 44, and the fixed drainage inner cylinder 42 to lift.

[0034] A limiting ring 421 is fixedly installed at the bottom of the inner wall of the fixed drainage guide cylinder 41. The lower surface of the fixed drainage inner cylinder 42 contacts the upper surface of the limiting ring 421. When the fixed drainage inner cylinder 42 descends to the lowest position, the lower surface of the fixed drainage inner cylinder 42 contacts the upper surface of the limiting ring 421. The limiting ring 421 limits the fixed drainage inner cylinder 42. When the multi-stage telescopic rod 471 is activated to contract again, it can drive the connecting seat 462 to drive the sliding shaft 46 and the wedge-shaped driving block 44 to move downward, and the second spring 461 contracts.

[0035] A fixed drainage bottom cylinder 48 is provided at the bottom end of the fixed drainage middle cylinder 47. A clamping strip 482 is fixedly installed at the top end of the fixed drainage bottom cylinder 48. A strip groove 472 corresponding to the clamping strip 482 is formed on the fixed drainage middle cylinder 47. The clamping strip 482 is slidably clamped in the corresponding strip groove 472. A lifting rod 481 is fixedly installed in the fixed drainage bottom cylinder 48. The driving end of the lifting rod 481 is fixedly installed with the bottom end of the fixed drainage middle cylinder 47. Controlling and activating the lifting rod 481 drives the fixed drainage middle cylinder 47, the fixed drainage guide cylinder 41, and the two positioning brackets 43 to lift. The clamping strip 482 slides in the corresponding strip groove 472 to adjust the positions of the fixed drainage guide cylinder 41 and the two positioning brackets 43.

[0036] The first clamping mechanism 8 clamps the top of the fixed drainage guide cylinder 41, and the second clamping mechanism 9 clamps the bottom of the fixed drainage bottom cylinder 48 to perform clamping and positioning on the top of the fixed drainage guide cylinder 41 and the bottom of the fixed drainage bottom cylinder 48. The first clamping mechanism 8 and the second clamping mechanism 9 are prior arts.

[0037] A downward extension bottom ring 111 is integrally formed at the bottom end of the storage frame 11. By providing the downward extension bottom ring 111, a space can be formed at the bottom of the storage frame 11 to enable the two positioning brackets 43 to be supported.

[0038] A feed inlet groove 101 is provided in the middle of the top end of the sintering furnace frame 2, facilitating automatic feeding through the feed inlet groove 101.

[0039] The feeding assembly 6 includes a guide frame cylinder 61, a first arc-shaped pusher 62 and a second arc-shaped pusher 63. Among them, a plurality of storage frames 11 are stacked in the guide frame cylinder 61. A first frame 611 is fixedly installed on the outer side of the guide frame cylinder 61, and the first frame 611 is fixedly installed on the top end of the auxiliary plate 3. The position of the first arc-shaped pusher 62 corresponds vertically to the position of the feed inlet groove 101, and the position of the second arc-shaped pusher 63 corresponds vertically to the position of the guide frame cylinder 61. A connecting frame 64 is fixedly connected between the first arc-shaped pusher 62 and the second arc-shaped pusher 63. A rotating shaft 641 is fixedly clamped in the middle of the connecting frame 64, and the rotating shaft 641 is rotatably installed on the top end of the sintering furnace frame 2. A motor 642 is fixedly installed on the outer side of the guide frame cylinder 61, and the driving end of the motor 642 is fixedly installed with the top end of the rotating shaft 641. By controlling and starting the motor 642, the rotating shaft 641 is driven to rotate, driving the connecting frame 64 to rotate, thereby driving the first arc-shaped pusher 62 and the second arc-shaped pusher 63 to rotate, and reciprocally switching the positions of the first arc-shaped pusher 62 and the second arc-shaped pusher 63;

[0040] Two symmetrically distributed support bottom plates 65 are fixedly clamped on the outer sides of the first arc-shaped pusher 62 and the second arc-shaped pusher 63. The upper surface of the support bottom plate 65 is flush with the lower surface of the guide frame cylinder 61. Storage grooves 601 are formed between the support bottom plate 65 and the first arc-shaped pusher 62 and between the support bottom plate 65 and the first arc-shaped pusher 62.

[0041] The positions of the storage grooves 601 correspond vertically to the position of the feed inlet groove 101 and the position of the guide frame cylinder 61 respectively. A placing mechanism 66 is provided at the top end of one of the support bottom plates 65. The placing mechanism 66 can automatically place the tantalum blocks to be processed.

[0042] A second frame 661 is fixedly installed on the outer side of the placing mechanism 66, and the second frame 661 is fixedly installed on the top end of the auxiliary plate 3. During use, the motor 642 is started, driving the rotating shaft 641 to rotate, driving the connecting frame 64 to rotate, driving the first arc-shaped pusher 62 and the second arc-shaped pusher 63 to rotate. The first arc-shaped pusher 62 pushes the storage frame 11 in the corresponding storage groove 601 out of the storage frame 11 group. On the upper surface of the auxiliary plate 3, at this time, the corresponding support bottom plate 65 moves to the lower surface of the guide frame cylinder 61 to support the lowermost storage frame 11 in the storage frame 11 group in the guide frame cylinder 61 until the pushed storage frame 11 is moved to the placing mechanism 66. The placing mechanism 66 automatically places the tantalum blocks to be processed in the storage frame 11, and then pushes the storage frame 11 again until the storage frame 11 with the tantalum blocks is pushed to the feed inlet groove 101, and the storage frame 11 falls through the feed inlet groove 101 and is sleeved on the fixed sparse

[0043] ...

[0044] On the outside of the guide cylinder 41, at this time, the second arc-shaped push frame 63 rotates to the lower surface of the guide frame cylinder 61, and the bottom storage frame 11 of the 5 11-group storage frames enters the storage slot 601 corresponding to the second arc-shaped push frame 63, and successively

[0045] automatically and intermittently feeds multiple storage frames 11.

[0046] Working principle: When in use, multiple storage frames 11 are stacked and placed in the guide frame cylinder 61. In the initial state, the second clamping mechanism 9 clamps the bottom of the fixed sieve bottom cylinder 48, but the first clamping mechanism 8 does not clamp the top of the fixed sieve guide cylinder 41, which does not affect subsequent feeding from the top;

[0047] Subsequently, the multi-stage telescopic rod 471 is activated to drive the connecting seat 462, the sliding shaft 46, the wedge-shaped driving block 44, and the fixed sieve inner cylinder 42 to lift and lower, moving the fixed sieve inner cylinder 42 and the two positioning frames 43 to the topmost position of the fixed sieve guide cylinder 41;

[0048] Then, the motor 642 is activated to drive the rotation shaft 641 to rotate, driving the connecting frame 64 to rotate, driving the first arc-shaped push frame 62 and the second arc-shaped push frame 63 to rotate. The first arc-shaped push frame 62 pushes the storage frame 11 in the corresponding storage slot 601 away from the 5 storage frame group. On the upper surface of the auxiliary plate 3, at this time, the corresponding support bottom plate 65

[0049] moves to the lower surface of the guide frame cylinder 61 to support the bottom storage frame 11 of the storage frame group in the guide frame cylinder 61 until the pushed storage frame 11 is moved to the placement mechanism 66. The placement mechanism 66 automatically places the tantalum block to be processed in the storage frame 11, and then pushes the storage frame 11 again until the storage frame 11 with the tantalum block is pushed to the feeding slot 101. The storage frame 11 falls through the feeding slot, is sleeved on the outside of the fixed sieve guide cylinder 41, and is supported by the two positioning frames 43;

[0050] Subsequently, the fixed sieve inner cylinder 42 and the two positioning frames 43 are lowered a certain distance, and the storage frame 11 follows and descends;

[0051] At this time, the second arc-shaped push frame 63 rotates to the lower surface of the guide frame cylinder 61, and the bottom storage frame 11 of the storage frame group enters the storage slot 601 corresponding to the second arc-shaped push frame 63, thereby automatically and intermittently placing multiple storage frames 11 outside the fixed sieve inner cylinder 42. Multiple storage frames 11 filled with tantalum blocks are stacked outside the fixed sieve inner cylinder 42, and the fixed sieve inner cylinder 42 descends to the lowest position, and the lower surface of the fixed sieve inner cylinder 42 contacts the upper surface of the limit ring 421;

[0052] Subsequently, the fixed sieve inner cylinder 42 and the two positioning frames 43 are lowered a certain distance, and the storage frame 11 follows and descends;

[0053] At this time, the second arc-shaped push frame 63 rotates to the lower surface of the guide frame cylinder 61, and the bottom storage frame 11 of the storage frame group enters the storage slot 601 corresponding to the second arc-shaped push frame 63, thereby automatically and intermittently placing multiple storage frames 11 outside the fixed sieve inner cylinder 42. Multiple storage frames 11 filled with tantalum blocks are stacked outside the fixed sieve inner cylinder 42, and the fixed sieve inner cylinder 42 descends to the lowest position, and the lower surface of the fixed sieve inner cylinder 42 contacts the upper surface of the limit ring 421;

[0054] Subsequently, control and activate the lifting rod 481 to drive the fixed sifting middle cylinder 47, the fixed guiding cylinder 41, and the two positioning frames 43 to lift and lower. The clamping strip 482 slides in the corresponding strip groove 472 to adjust the positions of the fixed guiding cylinder 41 and the two positioning frames 43, and move multiple storage frames 11 containing tantalum blocks to the sintering section 5 for sintering processing until the sintering processing is completed, improving the sintering processing efficiency of tantalum blocks;

[0055] Clamp the first clamping mechanism 8 at the top of the fixed guiding cylinder 41, and the second clamping mechanism 9 is not clamped at the bottom of the fixed sifting bottom cylinder 48, which does not affect subsequent discharging from the bottom;

[0056] At this time, activate the multi-stage telescopic rod 471 to contract again. When driving the sliding shaft 46 and the wedge-shaped driving block 44 to move downward, the second spring 461 contracts, the ball 431 rolls on the wedge-shaped driving block 44, and the first spring 452 slowly expands, driving the two positioning frames 43 to move towards each other and be received in the fixed guiding cylinder 41;

[0057] At this time, the bottommost storage frame 11 is no longer supported, and along the fixed guiding cylinder 41, the fixed sifting middle cylinder 47, and the fixed sifting bottom cylinder 48, it disengages from the fixed sifting mechanism 4 and automatically discharges from the sintering furnace through the sealing ring base 7;

[0058] During automatic discharging, when the bottom of the second-to-bottom storage frame 11 moves to the position of the two positioning frames 43, the multi-stage telescopic rod 471 can be reset, the second spring 461 is reset, quickly driving the wedge-shaped driving block 44 to move upward. The wedge-shaped driving block 44 abuts against the two positioning frames 43, causing the opposite sides of the two positioning frames 43 to quickly extend out of the outside of the fixed guiding cylinder 41 to support the second-to-bottom storage frame 11 until the bottommost storage frame 11 is discharged from the sintering furnace, and then discharging the second-to-bottom storage frame 11 from the sintering furnace, realizing the automatic intermittent discharging of tantalum blocks after sintering processing.
