Description

Technical Field

[0001] The utility model relates to the technical field of ceramic capacitor production equipment, in particular to a uniform material spreading mechanism for ceramic capacitors. Background Art

[0002] Ceramic capacitors are a general term for capacitors using ceramic materials as dielectric materials. Multilayer ceramic capacitors (MLCCs), also known as chip capacitors, multilayer capacitors, and stacked capacitors, are a type of ceramic capacitor. MLCCs are characterized by their small size, high capacitance, low loss at high frequencies, suitability for mass production, low price, and high stability. Multilayer ceramic capacitors (MLCCs) are composed of ceramic dielectric diaphragms with printed inner electrodes stacked in an offset manner. These are then sintered at high temperature to form a ceramic chip. Metal layers, which serve as outer electrodes, are then sealed at both ends of the chip.

[0003] The production process of multilayer ceramic capacitors (MLCCs): raw materials, casting, printing, lamination, pressing, cutting, debonding, sintering, chamfering, terminal electrode coating, electroplating, testing and sorting.

[0004] In the preparation stage of sintering, the ceramic capacitors to be sintered need to be spread on the sintering net, and then the sintering net is sent into the sintering furnace. The traditional material spreading mechanism includes a base, a support rod, a top plate, a feed box, a material channel and a straight vibrator. The base is connected to the top plate through the support rod, the feed box is fixedly arranged on the top plate, the material channel and the base are connected through the straight vibrator, and the material receiving port of the material channel is located below the material discharge port of the feed box, and the material channel is a smooth surface. The ceramic capacitors to be sintered fall from the feed box to the material receiving port of the material channel. Under the vibration of the straight vibrator, the ceramic capacitors gradually move toward the discharge port of the material channel and then fall on the sintering net. At the same time, the sintering net is also moving forward, so that the ceramic capacitors are spread on the sintering net. However, the traditional material spreading mechanism has disadvantages: since the material channel is a smooth surface, ceramic capacitors are easily stacked when they gather and move in the material channel, so that the ceramic capacitors that fall on the firing net are stacked up and down, that is, the ceramic capacitors are not evenly spread on the firing net, resulting in poor sintering quality of the ceramic capacitors. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a uniform material spreading mechanism for ceramic capacitors.

[0006] The utility model is implemented as follows: a uniform material spreading mechanism for ceramic capacitors, comprising:

[0007] Base, support rod, top plate, feed box, material channel, screed plate, height adjustment assembly and straight vibrator;

[0008] The base is connected to the top plate via the support rod, the feed box is fixedly arranged on the top plate, the material channel is connected to the base via the straight vibrator, the material receiving port of the material channel is located below the material discharge port of the feed box, and the material distribution plate is connected to the material channel via the height adjustment component;

[0009] The material channel includes a material guide plate and a left side plate, a right side plate and a rear side plate fixedly arranged on the material guide plate. The material leveling plate is located between the left side plate and the right side plate. The material leveling plate is also located above the material guide plate. The material guide plate has multiple material guide areas, and the material guide areas are distributed with material guide troughs. From the material receiving port of the material channel to the material discharge port of the material channel, the number of material guide troughs in the material guide area increases section by section and the width of the material guide trough decreases section by section.

[0010] Furthermore, the material guide plate has four sections of material guide areas, and the material guide area located at the material receiving port of the material channel is fan-shaped.

[0011] Furthermore, the height adjustment assembly includes a crossbeam and an adjusting bolt, the two ends of the crossbeam are fixedly connected to the left plate and the right plate respectively, the crossbeam is provided with a screw hole, and the upper end of the material leveling plate is provided with a strip hole, and the adjusting bolt passes through the strip hole and then is connected to the screw hole.

[0012] Furthermore, a quick clamp is included, and the feed box and the top plate are connected through the quick clamp.

[0013] Furthermore, it also includes a handle, which is fixedly arranged on the top of the feeding box.

[0014] Furthermore, it also includes a leakage box, which is fixedly connected to the base and is located below the discharge port of the material channel.

[0015] Furthermore, it also includes a scattered material collection box, which is slidably connected to the base.

[0016] Compared with the background technology, the advantages and beneficial effects of the present invention are:

[0017] A material channel with a unique structure is set up. The ceramic capacitors to be sintered move in the material guide troughs of the material channel. The material leveling plates help to distribute the ceramic capacitors in the material guide troughs of the material channel. The edges between adjacent material guide troughs help to separate the ceramic capacitors. Since the number of material guide troughs in the material guide area increases section by section and the width of the material guide trough decreases section by section, the ceramic capacitors are prevented from stacking. In this way, the ceramic capacitors are evenly spread on the firing net from the discharge port of the material channel, effectively avoiding the occurrence of material stacking on the firing net and improving the sintering quality of the ceramic capacitors.

DETAILED DESCRIPTION

[0035] The embodiment of the utility model provides a uniform material dispersing mechanism for ceramic capacitors, which overcomes the disadvantage in the background technology that ceramic capacitors are easily stacked when they gather and move in the material channel due to the smooth surface of the material channel; it achieves the technical effect of avoiding the stacking of ceramic capacitors when they reach the material channel discharge port, and evenly spreading the ceramic capacitors on the firing net from the material channel discharge port, effectively avoiding the stacking of ceramic capacitors on the firing net, and improving the sintering quality of ceramic capacitors.

[0036] The overall idea of ​​the technical solution of the embodiment of the utility model is as follows:

[0037] The ceramic capacitors to be sintered fall from the feed box to the receiving port of the material channel, and are distributed in the guide troughs of the material channel through the material distribution plate. Under the action of the straight vibrator, the ceramic capacitors move gradually in an orderly manner in the guide troughs toward the discharge port of the material channel. The edges between adjacent guide troughs help to separate the ceramic capacitors. Since the number of guide troughs in the guide area increases step by step and the width of the guide troughs decreases step by step, the ceramic capacitors are prevented from stacking. The width of a guide trough near the discharge port of the material channel can only accommodate one ceramic capacitor. Finally, the ceramic capacitors are evenly scattered on the sintering net.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0039] See Figures 1 to 15 , a preferred embodiment of the present utility model.

[0040] A uniform material spreading mechanism for ceramic capacitors, comprising:

[0041] Base 1, support rod 2, top plate 3, feed box 4, material channel 5, material leveling plate 6, height adjustment component 7 and straight vibrator 8;

[0042] The base 1 is connected to the top plate 3 via the support rod 2, the feed box 4 is fixedly mounted on the top plate 3, the material channel 5 is connected to the base 1 via the straight vibrator 8, the material receiving port of the material channel 5 is located below the material discharge port 41 of the feed box 4, and the material distribution plate is connected to the material channel 5 via the height adjustment assembly 7;

[0043] The material channel 5 includes a material guide plate 51 and a left side plate 52, a right side plate 53 and a rear side plate 54 fixedly arranged on the material guide plate 51. The material leveling plate 6 is located between the left side plate 52 and the right side plate 53. The material leveling plate 6 is also located above the material guide plate 51. The material guide plate 51 has multiple material guide areas, and the material guide areas are distributed with material guide grooves. There are edges 512 between adjacent material guide grooves. From the material receiving port of the material channel 5 to the material discharge port of the material channel 5, the number of material guide grooves in the material guide area increases section by section and the width of the material guide grooves decreases section by section.

[0044] The beneficial effect of the above technical solution is that a material channel 5 with a unique structure is set up, and the ceramic capacitors 10 to be sintered move in the material guide groove 511 of the material channel 5. The material leveling plate 6 helps to distribute the ceramic capacitors 10 in the material guide groove 511 of the material channel 5. The edges 512 between adjacent material guide grooves 511 help to separate the ceramic capacitors 10. Since the number of material guide grooves in the material guide area increases step by step and the width of the material guide groove decreases step by step, the ceramic capacitors 10 are prevented from stacking. In this way, the ceramic capacitors 10 are evenly scattered on the sintering net 20 from the discharge port of the material channel 5, effectively avoiding the occurrence of material stacking on the sintering net 20 and improving the sintering quality of the ceramic capacitors 10.

[0045] The feed box 4 is in the shape of a funnel. The straight vibrator 8, i.e., a linear vibrator, is a product of the prior art and its working principle is not described in detail.

[0046] The guide plate 51 has four sections of guide areas, and the guide area located at the material receiving port of the material channel 5 is fan-shaped. The beneficial effect of this technical solution is that it helps to distribute the ceramic capacitors to be sintered in the material channel 5. Among them, from the material receiving port of the material channel 5 to the material discharge port of the material channel 5, the four sections of guide areas are, in order, the first guide area 55, the second guide area 56, the third guide area 57, and the fourth guide area 58. The first guide area 55 is fan-shaped. The width of the first guide trough 550 of the first guide area 55 is twice the width of the second guide trough 560 of the second guide area 56. The width of the second guide trough 560 of the second guide area 56 is twice the width of the third guide trough 570 of the third guide area 57. The width of the third guide trough 570 of the third guide area 57 is twice the width of the fourth guide trough 580 of the fourth guide area 58. The fourth material guiding groove 580 of the fourth material guiding region 58 has a width sufficient to accommodate only one ceramic capacitor.

[0047] The height adjustment assembly 7 includes a crossbeam 71 and an adjustment bolt. The ends of the crossbeam 71 are fixedly connected to the left and right plates 52 and 53, respectively. The crossbeam 71 has screw holes. The upper end of the material leveling plate 6 has a strip hole 72, through which the adjustment bolt passes and then connects. This technical solution has the beneficial effect of varying the height of the material leveling plate 6 by adjusting the adjustment bolt in different positions within the strip hole 72, allowing adjustment based on the actual specifications of the ceramic capacitor.

[0048] The device further comprises a quick clamp 9, and the feed box 4 is connected to the top plate 3 via the quick clamp 9. The beneficial effect of this technical solution is that the feed box 4 is easy to disassemble and assemble.

[0049] The material supply box 4 further comprises a handle 42, which is fixedly arranged on the top of the material supply box 4. The beneficial effect of this technical solution is that the material supply box 4 is easy to carry.

[0050] The device further comprises a material leakage box 11, which is fixedly connected to the base 1 and is located below the discharge port of the material channel 5. The beneficial effect of this technical solution is that when the sintering net 20 leaves the discharge port of the material channel 5, the ceramic capacitor falls into the material leakage box 11.

[0051] The device further includes a spilled material collection box 12, which is slidably connected to the base 1. The beneficial effect of this technical solution is that when too many ceramic capacitors to be sintered are placed in the feed box 4 and the excess ceramic capacitors fall on the base 1, the staff can sweep the excess ceramic capacitors into the spilled material collection box 12.

[0052] The working method of the present invention is as follows: the staff puts the ceramic capacitors to be sintered into the feed box 4, and the ceramic capacitors to be sintered fall from the feed box 4 to the receiving port of the material channel 5, and are distributed in the guide troughs of the material channel 5 through the material leveling plate 6. Under the action of the straight vibrator 8, the ceramic capacitors are gradually moved in the guide troughs toward the discharge port of the material channel 5 in an orderly manner. The edges 512 between adjacent guide troughs help to separate the ceramic capacitors. As the number of guide troughs in the guide area increases section by section and the width of the guide trough decreases section by section, the ceramic capacitors are prevented from stacking. The width of a material guide trough can accommodate three ceramic capacitors. As the ceramic capacitors move in different material guide areas, the number of ceramic capacitors that a material guide trough can accommodate is reduced. The width of a material guide trough near the discharge port of the material channel 5 can only accommodate one ceramic capacitor. Finally, the ceramic capacitor falls on the sintering net 20, and the sintering net 20 moves above the leakage box 11, so that the ceramic capacitors are evenly scattered on the sintering net 20, avoiding the ceramic capacitors from stacking up and down on the sintering net 20. Finally, the sintering net 20 is sent to the sintering furnace, which is beneficial to the sintering quality of the ceramic capacitors.

[0053] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and are not intended to limit the scope of the present invention.
