Description

Technical Field

[0001] The present invention relates to the technical field of laser welding equipment, and more specifically, to a ceramic shell integrated laser welding device. Background Art

[0002] Ceramic shell integrated laser welding is a high-precision packaging technology that uses a high-energy laser beam to directly act on the interface between the ceramic base and the metal cover, achieving atomic-level metallurgical bonding through instantaneous high temperature, and forming an airtight seal without the need for traditional solder. This technology uses gradient laser parameters (such as pulse modulation and beam swing) to suppress thermal stress, combined with surface metallization pretreatment (such as sputtering titanium / platinum transition layer) and dynamic heat dissipation management (microchannel cooling and argon protection), effectively solving the problems of ceramic brittle cracking and metal oxidation. It is suitable for harsh scenarios such as high-power semiconductors, optoelectronic modules and aerospace devices, and has the advantages of high welding strength, good sealing and low thermal resistance.

[0003] However, the existing laser welding devices still have certain shortcomings in practical applications, especially for the processing of circular ceramic shells, the assembly accuracy of the circular ceramic base and the metal cover plate is required to reach micron-level concentricity, and the positioning device used in the existing laser welding device only relies on simple mechanical limiters. During the rotational welding process, the metal cover plate may still have a center deviation, which will lead to uneven weld thickness and reduced airtightness, especially significantly affecting the closing accuracy of the annular weld.

[0042] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0043] Please refer to Figures 1 to 3, A ceramic shell integrated laser welding device, comprising: a housing 2, a laser welding component 3, a rotating platform 4, a plurality of jigs 5, a self-rotation driving component 6, and an alignment component 7. Among them, half of the operating surface area of the housing 2 is exposed as the loading and unloading area of the ceramic shell 1, while the other half is isolated from the external space as the welding area. The laser welding component 3 is arranged in the welding area, which includes a welding head and related supporting and adjusting structures. Since it belongs to the prior art, its specific structure and principle will not be disclosed here. The top of the rotating platform 4 is half in the welding area and half in the loading and unloading area. By rotating the rotating platform 4, the ceramic shell 1 to be welded can be transferred to the welding area, and at the same time, the welded ceramic shell 1 can be transferred to the loading and unloading area. The plurality of jigs 5 are arranged equidistantly in a circle on the rotating platform 4, and are used to automatically clamp and fix the outer side of the ceramic base 11 in the ceramic shell 1 to be welded. Half of the number of jigs 5 is set to four, and of course, it can also be adjusted according to actual usage requirements. The self-rotation driving component 6 is arranged in the housing 2, and is used to drive the jig 5 at the preset welding station to rotate. When using the laser welding component 3 to perform welding operations on the ceramic shell 1, the self-rotation driving component 6 is docked with the bottom of the jig 5 at the welding station above it, and then the self-rotation driving component 6 drives the jig 5 and the ceramic shell 1 to rotate together, so that the laser welding component 3 can continuously weld the gap between the ceramic base 11 and the metal cover 12 in the ceramic shell 1.

[0044] Please refer to Figures 2 to 5 , The alignment component 7 is arranged on the housing 2 and is above the welding station to be. It includes: a linear telescopic source 71, a support base 72, a pressing component 73, and several contact and extrusion components 74. Among them, the linear telescopic source 71 can be a cylinder 61. The cylinder 61 is fixed on the housing 2 through a mounting bracket, and its telescopic end is arranged downward and is aligned with the processing station. The support base 72 is installed at the telescopic end of the linear telescopic source 71, and the pressing component 73 is arranged on the support base 72. It is used to apply a downward pressure to the top of the metal cover 12 in the housing 2 placed on the jig 5, so that the metal cover 12 will not shift in position due to the rotation of the jig 5 during the welding process. The several contact and extrusion components 74 are arranged equidistantly in a circle on the support base 72, and the number of them is generally set to four. One end of the four contact and extrusion components 74 is in transmission connection with the pressing component 73. By contacting the edge side of the metal cover 12 in the ceramic shell and generating an extrusion effect, the automatic alignment and correction function of the metal cover 12 and the ceramic base 11 to be coaxial is realized.

[0045] It should be noted that the use process of the above laser welding device is as follows:

[0046] The ceramic base 11 is directly placed on the fixture 5 in the loading and unloading area. The relevant electronic components have been installed in the ceramic base 11. Then the metal cover 12 is placed on the top of the ceramic base 11. Then, the assembled ceramic shell 1 is transferred to the processing station by rotating the rotating platform 4. At this time, the clamping component 73 is just above the metal cover 12. The self-rotating driving component 6 moves up to dock with the bottom of the fixture 5, and the fixture 5 is positioned so that it will not rotate relative to each other. Then, the linear telescopic source 71 moves down. Since the bottom of the contact extrusion component 74 is lower than the bottom of the clamping component 73, the bottom of the contact extrusion component 74 first contacts the edge side of the metal cover 12. As the linear telescopic source 71 continues to move downward, if the center of the metal cover plate 12 coincides with the center of the ceramic base 11, the contact and extrusion component 74 will not generate a lateral force on the metal cover plate 12 when moving downward. If the centers of the two circles do not completely coincide, the contact and extrusion component 74 will generate a lateral force on the metal cover plate 12 and squeeze the metal cover plate 12 to move to a standard state. Then, the bottom of the clamping component 73 begins to contact the top of the metal cover plate 12 to further press and position the corrected metal cover plate 12. At the same time, as the clamping component 73 further presses, the contact and extrusion component 74 can be driven to flip upward and separate from the edge of the metal cover plate 12. Fig. 9 In the state shown, there is no obstruction in the gap between the metal cover plate 12 and the ceramic base 11, which facilitates the subsequent welding operation.

[0047] Please refer to Figures 5 and 6 In order to achieve the clamping effect on the top of the metal cover plate 12, the present invention specifically sets a clamping assembly 73, which includes a slide rod 731 slidably arranged on the support base 72 and a clamping plate 732 rotating at the bottom end of the slide rod 731, and a support spring 733 is connected between the clamping plate 732 and the slide rod 731.

[0048] In addition, in order to speed up the heat dissipation of the ceramic shell 1 during welding and avoid deformation caused by local high temperature causing changes in internal stress of the clamping assembly 73, the clamping plate 732, the sliding rod 731 and the supporting spring 733 are all made of copper alloy, and a protective layer is provided at the bottom of the clamping plate 732. The protective layer is a graphene-silicone composite material with good thermal conductivity and softness, which can provide certain protection and heat conduction for the metal cover 12.

[0049] After the position of the metal cover 12 is corrected, under the driving action of the linear telescopic source 71, the clamping plate 732 can be gradually moved down to approach the top of the metal cover 12. After the two are in contact, the linear telescopic source 71 continues to extend, causing the support base 72 to move down along the surface of the slide rod 731 and squeeze the support spring 733. The linear telescopic source 71 further extends, on the one hand, in order to make the support spring 733 in a compressed state, the elastic force of the support spring 733 can be used to increase the clamping effect on the metal cover 12. At the same time, the metal cover 12 and the clamping plate 732 are in flexible contact, avoiding direct rigid contact to cause damage to the metal cover 12. On the other hand, the downward stroke is also for the convenience of driving the contact extrusion assembly 74 to perform a flipping action.

[0050] Please refer to Figures 5 to 9 On the basis of the above-mentioned clamping assembly 73, in order to realize the automatic correction of the metal cover plate 12 and cooperate with the clamping assembly 73, the present invention specifically discloses a contact extrusion assembly 74, which includes a rotating rod 741 hinged on the support base 72, a matching gear set 742 arranged at the hinged end of the rotating rod 741, and a ramp block 743 sliding at the bottom end of the rotating rod 741. The matching gear set 742 is composed of two mutually meshing transmission gears, one transmission gear is rotatably connected to the support base 72, and the other is connected to the rotating rod 741. The ramp block 743 is adapted to the metal cover plate 12, and the sliding rod 731 is provided with a tooth groove section 744 adapted to the matching gear set 742. A reset spring 745 is connected between the ramp block 743 and the rotating rod 741. A rolling shaft is provided at the bottom of the ramp block 743. The rotating rod 741, the matching gear set 742 and the ramp block 743 are all made of copper alloy materials to ensure good thermal conductivity.

[0051] During the downward movement of the contact extrusion assembly 74, the inclined surface of the inclined surface block 743 first contacts the edge side of the metal cover plate 12. As the inclined surface block 743 continues to move downward, if the position of the metal cover plate 12 is offset, the inclined surface of the inclined surface block 743 closer to the offset side will generate a lateral extrusion force on the metal cover plate 12. Due to the extrusion of the remaining inclined surface blocks 743 on the other sides of the metal cover plate 12, it can only move towards the standard position, ultimately aligning the center of the metal cover plate 12 with the ceramic base 11. After alignment, the bottom of the inclined surface block 743 contacts the top of the ceramic base 11. At this time, the pressing plate 732 has not yet contacted the top of the metal cover plate 12. Therefore, the linear telescopic source 71 will continue to extend, and the rotating rod 741 begins to extend into the inclined surface block 743 and squeezes the return spring 745 to contract, so as to adapt to the subsequent pressing action of the pressing plate 732. After the pressing plate 732 contacts the top of the metal cover plate 12, through the relative movement between the support base 72 and the sliding rod 731, the mating gear set 742 can be rotated along the tooth groove section 744, and the rotating rod 741 begins to flip upward following the mating gear set 742. Since a rolling shaft is provided at the bottom of the inclined surface block 743, the friction between the inclined surface block 743 and the ceramic base 11 can be reduced, enabling the inclined surface block 743 to easily overcome the friction and move downward following the rotating rod 741, and finally separating from the ceramic base 11. After the linear telescopic source 71 stops extending, the rotating rod 741 stops rotating. In this way, the coordinated action between the contact extrusion assembly 74 and the pressing assembly 73 is realized. After completing the position correction of the metal cover plate 12, it can be switched to the contraction state to avoid hindering the subsequent welding operation.

[0052] Please refer to Figures 6 to 9 , because during the welding process, relatively high problems will occur. In addition to relying on the active heat dissipation measures of the welding device, the passive heat dissipation measures of each component are also particularly crucial. In order to further improve the heat dissipation effect of the ceramic housing 1, the present invention continues to be optimized on the basis of the above solution. Specifically: movable rods 746 are slidably installed on both sides of the inclined surface block 743. The bottom end of the movable rod 746 is fixed with heat dissipation fins 747. The heat dissipation fins 747 are slidably retracted in the inclined surface block 743. A connecting spring 748 is connected between the movable rod 746 and the inclined surface block 743. An extrusion block 749 for generating an extrusion force on the top end of the movable rod 746 is provided on the support base 72. One side of the extrusion block 749 is provided with an arc surface. The end of the movable rod 746 in contact with the arc surface is a round rod, and a gradual extrusion force is generated on the end of the movable rod 746 through this arc surface.

[0053] When the inclined plane block 743 is not in contact with the metal cover plate 12, the end of the movable rod 746 is squeezed by the arc surface of the squeezing block 749, so that it squeezes the connecting spring 748, so that the connecting spring 748 is in a compressed state, and the heat dissipation fin 747 is stably contracted in the inclined plane block 743. After the inclined plane block 743 completes the position correction action of the metal cover plate 12, during the process of the rotating rod 741 turning upward, the movable rod 746 and the heat dissipation fin 747 of the inclined plane block 743 rotate together with the rotating rod 741, and the contact position between the end of the movable rod 746 and the squeezing block 749 changes, and under the elastic force of the connecting spring 748, the movable rod 746 gradually moves away from the rotating rod 741, and drives the heat dissipation fin 747 to extend outward. When the rotating rod 741 rotates to the preset position, the connecting spring 748 recovers, so that The heat dissipation fins 747 are fully unfolded, and the contact extrusion assembly 74 is automatically switched from the alignment state to the auxiliary heat dissipation state. Since the contact extrusion assembly 74 is far away from the ceramic shell 1 after flipping, the heat is transferred to the heat dissipation fins 747 through the heat conduction of the clamping assembly 73, which accelerates the dissipation of heat and avoids the heat from being concentrated around the ceramic shell 1. When the next ceramic shell 1 is welded, the contact extrusion assembly 74 is switched to the alignment state again, so that the ceramic fins are contracted into the inclined block 743. Through this contraction action, the dissolved metal particles splashed on the surface of the ceramic fins during the welding process can be scraped and cleaned to avoid affecting the subsequent heat dissipation effect. If the welding operation is completed, the heat dissipation fins 747 in the contracted state are separated from the external environment, which can also protect themselves. It can be seen that the contact extrusion assembly 74 set by the present invention has both an alignment state and an auxiliary heat dissipation state, which respectively realize the position correction of the metal cover plate 12 and the auxiliary heat dissipation function.

[0054] Please refer to Figure 1 , Figure 2 and Fig.11 The rotating platform 4 includes a motor drive assembly 41 arranged on the outer shell 2 and a rotating plate 42 rotating on the operating table of the outer shell 2. The motor drive assembly 41 is composed of a motor and a reducer, and the rotating end of the reducer is connected to the rotating plate 42.

[0055] Please refer to Figure 2 and Figure 4 The clamp 5 includes a support base 51 rotating on the rotating plate 42 and an automatic clamping member 52 arranged on the top of the support base 51. The automatic clamping member 52 includes four claws evenly distributed on the support base 51. The ceramic base 11 is clamped by controlling the four claws to approach synchronously. Since the automatic clamping member 52 belongs to the prior art, the specific structure is not disclosed here.

[0056] Please refer to Figure 3 , Figure 4 and Fig.10The self-rotation driving component 6 includes a cylinder 61 fixed in the outer shell 2 and a transmission member 62 fixed at the telescopic end of the cylinder 61. The transmission member 62 is composed of a slide and a docking shaft. The slide is slidably connected to the inner side of the outer shell 2, and the docking shaft is rotatably installed with the slide. A rotating motor 63 is provided at the bottom of the transmission member 62. The rotating end of the rotating motor 63 is connected to the docking shaft. The top of the transmission member 62 is used to cooperate and dock with the bottom of the support base 51.

[0057] When the self-rotating driving component 6 is in use, it extends upward through the cylinder 61, which can drive the transmission component 62 to move upward. After the top end of the docking shaft docks with the bottom of the clamp 5, the clamp 5 can be temporarily locked by the locking effect of the rotating motor 63. After that, the rotating motor 63 can be rotated to drive the docking shaft and the clamp 5 to rotate together, and cooperate with the welding components to complete the welding operation.

[0058] The embodiments of the present invention are described above, but the present invention is not limited to the above-mentioned specific implementation modes. The above-mentioned specific implementation modes are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms, all of which are within the protection of the present invention.
