Description

Technical Field

[0001] The present invention relates to the technical field of lamination machines, and in particular to a lamination device for chip-type multilayer capacitors. Background Art

[0002] Chip-type multilayer ceramic capacitors are made by stacking dielectric diaphragms with printed electrodes in an offset manner, sintering them at a high temperature once to form a chip, and then sealing the two ends of the chip with a metal layer to form a monolithic structure, so it is also called a monolithic capacitor. Multilayer capacitors usually require the use of a stacking machine for production and processing.

[0003] Traditional laminating machines feed materials from a single roll, and the material strip is cut by a circular knife contact cutting method to form a sheet structure, with low production efficiency and a complex roll structure that is difficult to adjust. When any two dielectric diaphragms are overlapped and laid flat for lamination, it is necessary to ensure that the two dielectric diaphragms are aligned with each other, and high requirements are placed on the alignment accuracy of the equipment. Moreover, after any two adjacent dielectric diaphragms are attached to each other, when the positions of the two are adjusted again, it is easy to cause damage to the dielectric layer located between the opposite side walls of the two ceramic dielectric diaphragms, causing the dielectric layer to easily fall off the dielectric diaphragms. Furthermore, when overlapping and laying the dielectric diaphragms for lamination, the bubbles between the two ceramic dielectric diaphragms are not easy to be discharged, which easily leads to a high defective rate of the product.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] An outer roller rack 14 is installed between the two mounting seats 13. The outer roller rack 14 is fixed to the mounting seat 13 by bolts. The cross section of the outer roller rack 14 is also circular. Two sets of first material transfer channels 15 that are interconnected are opened on the outer side wall of the outer roller rack 14. Two material guide channels 2 that are respectively connected to the first material transfer channels 15 are arranged in the chassis 1. The material guide channel 2 only transmits one dielectric diaphragm 35 at a time. The reverse extension lines of the two sets of first material transfer channels 15 intersect and bisect the circle where the outer roller rack 14 is located.

[0039] A material transfer rack 25 is rotatably arranged inside the outer roller frame 14, and a second material transfer channel 21 is arranged inside the material transfer rack 25.

In this way, the dielectric diaphragm 35 entering the first material transfer channel 15 from the material guide channels 2 on both sides of the chassis 1 enters the second material transfer channel 21 in an inclined state, thus avoiding the direct overlap of the entire dielectric diaphragm 35 with the surface of the stacked dielectric diaphragms 35, which may cause the coating on the dielectric diaphragm 35 to fall off when the overlapping position of the dielectric diaphragm 35 is adjusted later;

In this way, the guide frame 7 and the components installed on the guide frame 7 can be lifted up in the chassis 1 as the dielectric diaphragms 35 are stacked one by one on the bearing platform 5, that is, the dielectric diaphragms 35 stacked to a certain thickness are used to make the material transfer frame 25 installed on the guide frame 7 gradually increase with the stacking height of the dielectric diaphragms 35 on the bearing platform 5, and the multi-layer dielectric diaphragms 35 are temporarily pressed down and positioned, thereby improving the adaptability of the present structure.

[0041] In some technical schemes of the present invention, the driving assembly includes two guide seats 36 arranged in pairs, and the two guide seats 36 are respectively connected to the two mounting seats 13 through two cross bars. Grooves matching the two guide seats 36 are provided on the two opposite side walls of the guide frame 7, and the cross-section of the groove is rectangular or wedge-shaped. Preferably, one side is rectangular and the other side is wedge-shaped; a part of the guide seat 36 is embedded in the groove, and a mounting groove is provided on the side wall opposite to the groove. A transmission wheel 37 is provided in the mounting groove through the rotation of an axial rod. The transmission wheel 37 is a rubber-type gear structure with good soundproofing ability. A driving motor connected to the transmission wheel 37 is provided in the mounting groove; and a toothed belt is provided on the bottom of the mounting groove to mesh with the transmission wheel 37, so as to improve the transmission efficiency of the two and achieve a certain automatic locking ability.

[0042] Preferably, both ends of the material transfer rack 25 are disc-shaped structures, whose outer diameters are mutually adapted to the inner diameters of the outer rolling rack 14 , and the middle part is a cuboid structure with a rectangular cross-section, and the second material transfer channel 21 is arranged in the middle of the material transfer rack 25 .

[0043] In some technical schemes of the present invention, the adjustment mechanism includes a sleeve 3 installed at one end of the material transmission frame 25, the sleeve 3 is embedded in the end of the material transmission frame 25, a transmission rod 34 is passed through the sleeve 3, the transmission rod 34 can slide along the axial direction of the sleeve 3, the transmission rod 34 does not make a circular motion in the sleeve 3, the transmission rod 34 and the mounting seat 13 on the same side are connected by a flange and bolts, two cross bars are passed through the guide seat 36, and the two can slide relative to each other, and the cross bar is fixedly connected to the side wall of the mounting seat 13; a second ratchet 28 and a first ratchet 27 are rotatably provided in the outer rolling frame 14, the second ratchet 28 and the first ratchet 27 are both sleeved on the outer wall of the transmission rod 34, at least three tooth blocks are provided on the outer wall of the transmission rod 34, and the axial holes of the second ratchet 28 and the first ratchet 27 are provided with tooth grooves adapted to the tooth blocks, so that the transmission rod 34 can slide along the axial direction of the sleeve 3 to achieve engagement with the second ratchet 2 8 or the first ratchet 27, when the transmission rod 34 is transmission-connected with the second ratchet 28, the transmission rod 34 idles in the axial hole of the first ratchet 27; when the transmission rod 34 is transmission-connected with the first ratchet 27, the transmission rod 34 idles in the axial hole of the second ratchet 28, so that the transmission mechanism arranged on the supporting platform 5 can drive the second ratchet 28 or the first ratchet 27 to move independently, so as to realize the forward and reverse movement of the material transfer rack 25 in the outer roller rack 14, thereby changing the feeding direction of the dielectric diaphragm 35. In this way, when the driving component drives the material transfer rack 25 and the outer roller rack 14 from the left end of the mechanism to the right end of the mechanism or from the right end of the mechanism to the left end of the mechanism, the dielectric diaphragm 35 can be introduced into the second material transfer channel 21 connected with any group of the first material transfer channels 15 through the material guide channel 2, so as to achieve the purpose of cross-stacking the dielectric diaphragms 35 and speed up the stacking efficiency.

[0044] In some technical schemes of the present invention, the transmission mechanism includes a guide groove 22, which is arranged on the upper surface of the bearing platform 5 along the movement direction of the outer roller frame 14, and the cross-section of the guide groove 22 is rectangular. A protrusion 38 is provided on the side wall of the mounting seat 13 through a pin shaft, and a part of the protrusion 38 is embedded in the guide groove 22. The groove width in the middle of the guide groove 22 is the thickness of the protrusion 38. The first offset plate 20 and the second offset plate 33 are respectively provided at both ends of the guide groove 22. The width of the first offset plate 20 and the second offset plate 33 are both the thickness of the mounting seat 13. The inclined surface on the first offset plate 20 is arranged opposite to the inclined surface on the second offset plate 33. Such an arrangement facilitates guiding the mounting seat 13 into the adjustment area formed by the first offset plate 20 or the second offset plate 33 in the guide groove 22, and the width of the adjustment area is the thickness of the protrusion 38; bearing platform 5 is provided with a first limiting strip 18 and a second limiting strip 31, the top of the first limiting strip 18 is provided with a first limiting tooth 19 adapted to the ratchet teeth of the second ratchet 28, and the top of the second limiting strip 31 is provided with a second limiting tooth 32 adapted to the ratchet teeth of the first ratchet 27; the side wall of the mounting seat 13 is provided with a first pawl 30 engaged with the first ratchet 27, and the first pawl 30 is used to prevent the first ratchet 27 from rotating in the opposite direction; the side wall of the mounting seat 13 is provided with a second pawl 29 engaged with the second ratchet 28; the second pawl 29 is used to prevent the second ratchet 28 from rotating in the opposite direction; when the protrusion 38 is located in the guide groove 22 area between the first offset plate 20 and the second offset plate 33, the second ratchet 28 and the first ratchet 27 are both engaged with the transmission rod 34, and the above structure is in a locked state, and the relative position relationship between the material transfer rack 25 and the outer rolling rack 14 does not change.

[0045] like Figure 7 , Figure 8 As shown, in order to show the motion state of the second ratchet 28, the mounting base 13 needs to be seen and the structure related to the first ratchet 27 is hidden. Figure 8 A second ratchet wheel 28 in a dotted structure;

[0046] The motion state of the second ratchet 28 is as follows: when the projection 38 drives the mounting seat 13 to move to the left on the bearing platform 5 in the horizontal direction, and the projection 38 enters the adjustment area formed by the first offset plate 20 in the guide groove 22, the transmission rod 34 slides in the shaft sleeve 3 along the axial direction of the shaft sleeve 3 under the push of the mounting seat 13, and is transmission-connected with the second ratchet 28, and is disengaged from the first ratchet 27; when the transmission rod 34 is transmission-connected with the second ratchet 28, the transmission rod 34 idles in the shaft hole of the first ratchet 27, at this time, when the projection 38 drives the mounting seat 13 to continue to move to the left on the bearing platform 5 in the horizontal direction, the second ratchet 28 rotates in the counterclockwise direction under the restriction of the first limiting tooth 19 provided on the top of the first limiting strip 18;

[0047] like Figure 7 , Fig. 9 As shown, in order to show the motion state of the first ratchet 27, the mounting seat 13 needs to be seen and the structure related to the second ratchet 28 is hidden. Fig. 9 A first ratchet 27 in a dotted structure;

[0048] The motion state of the first ratchet 27 is as follows: when the projection 38 drives the mounting seat 13 to move rightward on the bearing platform 5 in the horizontal direction, and the projection 38 enters the adjustment area formed by the second offset plate 33 in the guide groove 22, the transmission rod 34 slides on the shaft sleeve 3 along the axial direction of the shaft sleeve 3 under the traction of the mounting seat 13, disengages from the second ratchet 28, and is transmission-connected with the first ratchet 27; when the transmission rod 34 is transmission-connected with the first ratchet 27, the transmission rod 34 idles in the shaft hole of the second ratchet 28; at this time, when the projection 38 drives the mounting seat 13 to continue to move rightward on the bearing platform 5 in the horizontal direction, the second ratchet 28 rotates in the clockwise direction under the restriction of the second limiting tooth 32 at the top of the second limiting strip 31;

[0049] In this way, the transmission mechanism disposed on the support platform 5 can drive the second ratchet 28 or the first ratchet 27 to move independently.

[0050] Through the above structure, when the driving component drives the material transfer rack 25 and the outer roller rack 14 from the left end of the mechanism to the right end of the mechanism or from the right end of the mechanism to the left end of the mechanism, the dielectric diaphragm 35 can be introduced into the second material transfer channel 21 connected to any group of first material transfer channels 15 through the material guide channel 2, thereby achieving the purpose of cross-stacking the dielectric diaphragms 35 and accelerating the stacking efficiency.

[0051] The pawl on the second ratchet 28 is arranged on the second ratchet 28 in a counterclockwise direction; the pawl on the first ratchet 27 is arranged on the first ratchet 27 in a clockwise direction.

[0052] In some technical schemes of the present invention, mounting frames 16 are rotatably provided on both sides of the mounting seat 13 through a pin shaft, and a pressure roller 17 is rotatably provided inside the mounting frame 16. The length of the pressure roller 17 is greater than the width of the dielectric diaphragm 35, and a torsion spring connected to the mounting seat 13 is provided on the rotating shaft of the mounting frame 16. In this way, the pressure rollers 17 installed on both sides of the mounting seat 13 through the mounting frame 16 have room to move when pressing down the dielectric diaphragm 35, and can make circular motion around the mounting point of the mounting frame 16, thereby preventing the pressure rollers 17 from applying a large pressure to the dielectric diaphragm 35, resulting in poor overlapping quality of the dielectric diaphragm 35.

[0053] In some technical solutions of the present invention, through grooves are provided on both sides of the support platform 5, and limit plates 12 are installed in the through grooves to limit the two ends of the dielectric diaphragm 35, so as to avoid uneven ends of the stacked multi-layer dielectric diaphragms 35, resulting in a high lamination defect rate of the dielectric diaphragms 35.

[0054] In some technical solutions of the present invention, the limit plate 12 is slidably disposed in the through groove, a sink groove is provided at the lower side of the limit plate 12, a third spring 24 is provided in the sink groove, a connecting rod 23 connected to the third spring 24 is slidably disposed in the sink groove, and a lifting frame 6 connected to the guide rod 11 is provided on the connecting rod 23. Through the above structure, the limit plate 12 can be raised as the stacking height of the dielectric diaphragms 35 on the bearing platform 5 increases successively, and moves to a state flush with the dielectric diaphragm 35 located at the uppermost layer, and limits it.

[0055] Guide slopes are provided on the opposite side walls of the two limit plates 12; after the driving assembly drives the outer roller frame 14 and the material transfer frame 25 which are slidably arranged on the guide frame 7 through the mounting seat 13 to the end of the dielectric diaphragm 35, the output end of the corresponding first material transfer channel 15 on the outer roller frame 14 can be placed in the area where the dielectric diaphragm 35 and the limit plate 12 abut against each other, so that the end of the unbonded dielectric diaphragm 35 is aligned with the end of the already stacked dielectric diaphragm 35. At this time, the pressure roller 17 located on the mounting seat 13 presses the limit plate 12 down into the supporting platform 5, and presses the end of the unbonded dielectric diaphragm 35 onto the end of the already stacked dielectric diaphragm 35, thereby improving the overlapping accuracy of the two.

[0056] In some technical solutions of the present invention, a plurality of transfer rollers 26 are rotatably provided on two opposite side walls of the second material transfer channel 21 to ensure the smoothness of the dielectric diaphragm 35 when it is transferred in the second material transfer channel 21, and to avoid the problem of the dielectric diaphragm 35 contacting the side wall of the second material transfer channel 21 and causing the coating to be damaged.

[0057] The working principle of the lamination equipment is as follows: in the initial state, the base layer is laid in the limiting area formed by the two limiting plates 12 on the bearing platform 5. At this time, the driving component and the outer roller frame 14 are located on the left side of the chassis 1. The base layer enters the first material transfer channel 15 located on the upper right side of the outer roller frame 14 through the material guide channel 2 located on the right side of the chassis 1, and then enters the second material transfer channel 21. Subsequently, the driving motor is started, and the guide seat 36 is driven by the transmission wheel 37 to make a linear motion in the horizontal direction in the guide frame 7, that is, it moves from the left side of the bearing platform 5 to the right side of the bearing platform 5, and is located at the first The base layer in the second material transfer channel 21 will gradually be spread on the supporting platform 5, and the pressure roller 17 located on the left side of the mounting seat 13 will squeeze the upper surface of the base layer to discharge the air remaining between the base layer and the supporting platform 5 when the base layer and the supporting platform 5 are in contact with each other; until the driving component drives the outer rolling frame 14 and the material transfer frame 25 slidingly arranged on the guide frame 7 through the mounting seat 13 to the other end of the limiting area formed by the two limiting plates 12, the laying of the base layer is completed; after the outer rolling frame 14 and the material transfer frame 25 gradually reach the limiting plate 12 at the right end of the supporting platform 5, the second limiting tooth 32 will gradually embed into the first The transmission rod 34 slides along the axial direction of the shaft sleeve 3 under the traction of the mounting seat 13 moving in the guide groove 22, disengages from the second ratchet 28, and gradually meshes with the first ratchet 27 to achieve transmission connection. At this time, the first ratchet 27 rotates clockwise. When the outer roller frame 14 and the material transfer frame 25 continue to move again under the drive of the driving component, the material transfer frame 25 will rotate clockwise in the outer roller frame 14 driven by the first ratchet 27, and the second material transfer channel 21 will gradually align with the first material transfer channel 15 located at the upper left of the outer roller frame 14. The two parts are aligned and connected. At this time, the top of the limit plate 12 is completely placed in the supporting platform 5 under the pressure of the pressure roller 17. The dielectric diaphragm 35 will enter the first material transfer channel 15 located on the upper left of the outer roller frame 14 through the material guide channel 2 located on the left side of the chassis 1, and then enter the second material transfer channel 21 and be laid on the base layer. Then the above structure of the driving component continues to move, and the pressure roller 17 presses the end of the dielectric diaphragm 35 on the base layer to prevent the two from shifting. Then the dielectric diaphragm 35 enters the stacking and laying process, and the stacking and laying of the dielectric diaphragm 35 is completed multiple times in this way.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
