Description

Technical Field

[0001] This application relates to the field of electronic component packaging technology, and in particular to a seam welding packaging device. Background Technology

[0002] Electronic components, as core components of various electronic devices, directly determine the overall performance of these devices through their operational stability and lifespan. To protect electronic components (such as chips and semiconductors) from external environmental factors like humidity, dust, and harmful gases, and to prevent performance degradation during use, encapsulation is necessary. Seam welding, a common encapsulation technology for metal / ceramic housings, offers significant advantages such as excellent sealing performance, low cost, ease of operation, high efficiency, and reworkability. It can achieve a hermetically tight seal by filling the housing cavity with nitrogen or drawing a vacuum, completely isolating the cavity from the outside environment. Therefore, it is widely used in the field of electronic component encapsulation where reliability is paramount.

[0003] Existing seam welding packaging equipment for electronic components mainly applies pressure to the assembled metal cover and base using roller electrodes, while simultaneously applying pulsed current. The heat generated by the current passing through the contact resistance melts the metal at the contact point, forming a solder joint. The rolling of the roller electrodes then causes adjacent solder joints to overlap, thereby achieving hermetic encapsulation of the component. However, existing seam welding packaging equipment often relies on manual operation or multiple independent, decentralized devices to complete the entire packaging process, including loading, alignment, cover removal, welding, and finished product transfer. This lack of automation and continuity leads to low production efficiency, and manual intervention can easily introduce alignment errors and contamination. Summary of the Invention

[0004] To address the problems of low automation, frequent manual operation, low packaging efficiency, and unstable packaging quality in existing seam welding packaging equipment, this application provides a seam welding packaging device.

[0005] Firstly, the seam welding packaging equipment provided in this application adopts the following technical solution:

[0006] A seam welding packaging apparatus, the seam welding packaging apparatus comprising:

[0007] The housing has a sealed cavity, and a mounting base is provided inside the sealed cavity;

[0008] The positioning mechanism includes a positioning platform disposed on the mounting base;

[0009] The feeding mechanism includes two feeding components disposed within the sealed cavity. The two feeding components are spaced apart in the left-right direction, and one of the feeding components is used to supply the substrate and the other feeding component is used to supply the cover.

[0010] The material transfer mechanism includes two material transfer components installed on the mounting base. The two material transfer components are respectively arranged corresponding to the two material feeding mechanisms. One of the material feeding components is used to transfer the substrate to the positioning table, and the other material transfer component is used to transfer the cover to the substrate of the positioning table.

[0011] The packaging mechanism includes a seam welding machine disposed within the sealed cavity, the seam welding machine being movably configured such that the roller electrode of the seam welding machine can perform roll welding on the substrate and the cover.

[0012] By adopting the above technical solution and setting up a sealed cavity, a controlled environment can be provided for the entire packaging process. From material supply to welding completion, external air and impurities are isolated throughout the process, effectively preventing oxidation of electronic components and ensuring the electrical performance and service life of the components. By setting up parallel operation of dual feeding and dual transfer, the limitations of a single feeding and transfer structure can be broken, realizing the synchronization of substrate and cover supply and transfer, greatly improving production continuity. At the same time, the movable seam welding machine can improve the equipment's adaptability to workpieces of different specifications, ensuring that all types of workpieces can obtain accurate welding results, thus improving the overall packaging quality and production efficiency. In this way, the coordinated action of various mechanisms constructs a complete automated packaging process, which can not only avoid the alignment errors and contamination problems caused by manual operation, but also significantly improve the airtightness and reliability of the finished product, thereby solving the problems of low packaging efficiency and unstable packaging quality of existing seam welding packaging equipment.

[0013] Optionally, the packaging mechanism further includes:

[0014] A first packaging structure includes a first movable base and a first packaging driving structure. The first movable base is movably mounted on a mounting base in a front-rear direction, and the first packaging driving structure is driven to connect to the first movable base.

[0015] The second packaging structure includes a second movable seat and a second packaging driving structure. The second movable seat is movably mounted on the first movable seat in the vertical direction, and the second packaging driving structure is driven to connect to the second movable seat.

[0016] The seam welding machine is mounted on the first movable seat.

[0017] By adopting the above technical solutions, the position of the seam welding machine can be precisely adjusted in the front-back or up-down direction, which can cover the welding needs of most conventional workpieces. It can adapt to base bodies and covers of different sizes and thicknesses without changing special tooling, reducing equipment adaptation costs and changeover time. It can also ensure that the roller electrode and the weld are perfectly aligned, so that the welding current and pressure are evenly distributed, reducing welding defects such as incomplete welding and missing welding, and improving the sealing performance and structural strength of the weld.

[0018] Optionally, two seam welding machines are provided, and the two seam welding machines are arranged at intervals along the front-to-back direction.

[0019] By adopting the above technical solution and using a parallel double-seam welding machine, welding time can be significantly shortened, which is especially suitable for packaging rectangular or other workpieces with opposite weld seams. This helps to improve the batch production capacity of the equipment and ensures that the welding current, pressure, speed and other parameters of the two opposite weld seams are completely consistent. This avoids differences in weld quality caused by changes in equipment status or environment during multiple welding operations and improves the consistency of finished products.

[0020] Optionally, the feeding assembly includes a feeding box and a conveying structure. The feeding box is disposed in the sealed cavity for placing the feeding tray, and the conveying structure is installed on the mounting base for moving the tray out or in.

[0021] By adopting the above technical solution, and through the cooperation of the feeding box and the transfer structure, it is possible to realize the automatic entry and exit management of materials in a sealed environment, avoiding the damage to the sealed environment and efficiency loss caused by frequent manual intervention, and providing a basic guarantee for realizing long-term unattended continuous automated production, thereby greatly improving the overall operating efficiency of the equipment.

[0022] Optionally, each of the said transfer components includes:

[0023] The first material transfer structure includes a first material transfer seat and a first material transfer drive structure. The first material transfer seat is movably mounted on the mounting seat in the left-right direction, and the first material transfer drive structure is driven to connect to the first material transfer seat.

[0024] The second material transfer structure includes a second material transfer seat and a second material transfer drive structure. The second material transfer seat is movably mounted on the first material transfer seat in a vertical direction, and the second material transfer drive structure is driven to connect to the second material transfer seat.

[0025] A material transfer and picking structure is provided on the second material transfer seat for picking up the substrate or the cover.

[0026] By adopting the above technical solution, the position of the material picking structure can be adjusted in the left-right and up-down directions. This can not only adapt to material feeding components and positioning platforms with different spacings, but also meet the material transfer needs of different specifications without major adjustments to the equipment structure. It can also ensure that the substrate and cover can be accurately placed in the designated position on the positioning platform, laying the foundation for subsequent precise welding and reducing packaging defects caused by material transfer deviation.

[0027] Optionally, the two material transfer picking structures include a first material transfer picking structure, the first material transfer picking structure comprising:

[0028] The first material transfer pick-up seat is rotatably set about an axis extending in the left and right directions;

[0029] A first material transfer and pickup drive structure is disposed on the second material transfer base and is drivenly connected to the first material transfer and pickup base; and,

[0030] Two first material transfer pickup parts are installed on the first material transfer pickup base and are spaced apart circumferentially along the first material transfer pickup base.

[0031] By adopting the above technical solution, the two first material transfer and picking units can alternately be in working position. In actual operation, one picking unit can be used to pick up the substrate to be processed, and the other picking unit can be used to pick up the finished product. In order to quickly complete the removal of the finished product and the placement of the raw material at the same station by rotating the first material transfer and picking seat, the loading and unloading cycle can be greatly optimized, the number of reciprocating movements of the material transfer component can be reduced, and the seamless connection of picking and placing actions can be achieved, thereby helping to greatly improve the operation efficiency of the substrate transfer process.

[0032] Optionally, the two material transfer picking structures include a second material transfer picking structure, the second material transfer picking structure comprising:

[0033] A second material transfer pick-up seat is installed on the second material transfer seat; and...

[0034] The second material transfer pickup unit is rotatably mounted on the second material transfer pickup base about an axis extending vertically.

[0035] By adopting the above technical solution, the alignment accuracy between the cover and the base can be improved, effectively compensating for the slight angular deviations generated during the feeding or transfer process, ensuring that the cover is accurately installed on the base, and providing a good foundation for subsequent welding.

[0036] Optionally, the positioning mechanism further includes:

[0037] A first positioning structure includes a first positioning seat and a first positioning drive structure. The first positioning seat is movably mounted on the mounting base in a left-right direction, and the first positioning drive structure is driven to connect to the first positioning seat.

[0038] The second positioning structure includes a second positioning seat and a second positioning drive structure. The second positioning seat is movably mounted on the first positioning seat in the front-back direction, and the second positioning drive structure is driven to connect to the second positioning seat.

[0039] The positioning platform is rotatably mounted on the second positioning seat about an axis extending vertically.

[0040] By adopting the above technical solution, not only can precise centering and correction be achieved, but also the packaging requirements of components of various sizes and shapes can be flexibly met. At the same time, through the rotation and cooperation of the workpiece, full-circumference airtight seam welding can be completed with only two sets of parallel welding wheels, which helps to simplify the structure of the packaging mechanism.

[0041] Optionally, the seam welding and sealing equipment further includes an exhaust gas circulation mechanism, which includes a circulation pipeline and a filter device. One end of the circulation pipeline is located on the mounting base and corresponds to the positioning platform, while the other end is connected to the sealing cavity. The filter device is located on the circulation pipeline.

[0042] By adopting the above technical solutions, welding fumes can be removed in a timely manner to prevent them from contaminating the surface of components or affecting the detection accuracy of the optical vision system. At the same time, the purity of the inert gas in the sealed cavity can be maintained to achieve gas recycling, which greatly reduces the cost of inert gas consumption and helps to ensure the cleanliness of the process environment.

[0043] Optionally, the seam welding and sealing equipment includes a first camera device and a second camera device. The first camera device is disposed above the positioning platform to obtain the orientation of the substrate on the positioning platform, and the second camera device is disposed on the mounting base to obtain the orientation of the cover.

[0044] By adopting the above technical solution and setting up the first and second camera devices, the alignment accuracy of the substrate and the cover can be greatly improved, effectively compensating for minor deviations generated during material feeding and transfer, avoiding welding defects caused by misalignment, and helping to improve product quality.

[0045] In summary, this application includes at least one of the following beneficial technical effects:

[0046] 1. By constructing an integrated sealed cavity environment, all key processes such as material feeding, material transfer, positioning, and welding are integrated into one, realizing fully automated and continuous production from material supply to welding completion, completely avoiding manual intervention and material exposure between processes, thereby greatly improving packaging efficiency and operational safety.

[0047] 2. By adopting a parallel collaborative design of dual feeding components and dual transfer components, the synchronous and efficient supply and transfer of the substrate and the cover are realized. Combined with a movable seam welding machine and an adjustable positioning mechanism, the equipment's adaptability to workpieces of different specifications and welding accuracy are significantly enhanced, effectively ensuring the stability and consistency of packaging quality.

[0048] 3. By setting up a sealed cavity and combining it with a vacuum filling and exhaust gas circulation system, a pure and controllable inert gas protective environment is provided for the entire welding process, which fundamentally prevents the oxidation and contamination of components in critical processes, thereby ensuring the high airtightness and long-term reliability of the final packaged product.

[0063] The following is in conjunction with the appendix Figure 1 - Appendix Figure 11 This application will be described in further detail below.

[0064] In one embodiment of this application, please refer to Figures 1 to 3 The seam welding and packaging equipment 100 includes a housing 1, a positioning mechanism 2, a feeding mechanism, a transferring mechanism, and a packaging mechanism 5. The housing 1 has a sealed cavity, and a mounting base 11 is provided inside the sealed cavity. The positioning mechanism 2 includes a positioning platform 21 provided on the mounting base 11. The feeding mechanism includes two feeding components 3 provided in the sealed cavity. The two feeding components 3 are spaced apart in the left and right direction. One feeding component 3 is used to supply the substrate, and the other feeding component 3 is used to supply the cover. The transferring mechanism includes two transferring components 4 installed on the mounting base 11. The two transferring components 4 are respectively provided corresponding to the two feeding mechanisms. One feeding component 3 is used to transfer the substrate to the positioning platform 21, and the other transferring component 4 is used to transfer the cover onto the substrate on the positioning platform 21. The packaging mechanism 5 includes a seam welding machine 51 provided in the sealed cavity. The seam welding machine 51 is movably arranged so that the roller electrode 511 of the seam welding machine 51 can perform roll welding on the substrate and the cover.

[0065] It should be noted that the feeding component 3 serves as a material library, storing the substrate and cover in batches; the material transfer component 4 serves as an execution unit, automatically picking up and placing materials between the feeding point and the processing point (positioning table 21); the positioning table 21 serves as a fixed workstation, supporting and stabilizing the workpiece to be welded; and finally, the welding is completed by the movable seam welding machine 51. Furthermore, during encapsulation, the two feeding components 3 of the feeding mechanism independently supply the substrate and the cover inside the sealed cavity, and the two transfer components 4 respectively grasp the substrate and the cover and accurately transfer them to the positioning table 21 for assembly. The positioning table 21 stably supports the assembled workpiece, and the movable seam welding machine 51 adjusts its own position so that the roller electrode 511 accurately acts on the connection between the substrate and the cover, and the encapsulation is completed by roll welding. Each process is carried out in a coordinated manner in the sealed space, so that the entire encapsulation process is completely isolated from the external air, avoiding oxidation of electronic components during the transmission and welding stages. The combination of dual feeding and dual transfer enables synchronous or continuous feeding of the substrate and the cover, reducing the waiting time of the process, while the movable seam welding machine 51 ensures the accuracy of the welding position.

[0066] In this embodiment, by setting up a sealed cavity, a controlled environment can be provided for the entire packaging process. From material supply to welding completion, external air and impurities are isolated throughout the process, effectively preventing oxidation of electronic components and ensuring the electrical performance and service life of the components. By setting up parallel operation of dual feeding and dual transfer, the limitations of a single feeding and transfer structure can be broken, realizing the synchronization of substrate and cover supply and transfer, greatly improving production continuity. At the same time, the movable seam welding machine 51 can improve the equipment's adaptability to workpieces of different specifications, ensuring that all types of workpieces can obtain accurate welding results, and improving the overall packaging quality and production efficiency. In this way, the coordinated action of each mechanism constructs a complete automated packaging process, which can not only avoid the alignment error and contamination problems caused by manual operation, but also significantly improve the airtightness and reliability of the finished product, thereby solving the problems of low packaging efficiency and unstable packaging quality of existing seam welding packaging equipment 100.

[0067] In one embodiment of this application, please refer to the following: Figures 3 to 5The packaging mechanism 5 also includes a first packaging structure 52 and a second packaging structure 53. The first packaging structure 52 includes a first movable seat 521 and a first packaging drive structure 522. The first movable seat 521 is movably mounted on the mounting base 11 in the front-to-back direction. The first packaging drive structure 522 is driven to connect the first movable seat 521. The second packaging structure 53 includes a second movable seat 531 and a second packaging drive structure 532. The second movable seat 531 is movably mounted on the first movable seat 521 in the up-down direction. The second packaging drive structure 532 is driven to connect the second movable seat 531. The first packaging drive structure 522 drives the first movable seat 521 to move in the front-to-back direction, thereby driving the seam welding machine 51 to adjust its position in the front-to-back direction simultaneously and accurately align it with different welding parts in the front-to-back direction of the workpiece. The second packaging drive structure 532 drives the second movable seat 531 to move in the up-and-down direction, thereby driving the seam welding machine 51 to adjust its height to adapt to workpieces of different thicknesses or to precisely control the welding pressure. This allows the seam welding machine 51 to be flexibly adjusted in the front-to-back and up-and-down directions, ensuring that the roller electrode 511 is precisely aligned with the weld seam of the substrate and the cover, significantly improving the adjustment accuracy of the welding position, enabling the equipment to adapt to more specifications of workpieces, while ensuring welding pressure and contact stability. Thus, by setting the first encapsulation structure 52 and the second encapsulation structure 53, the position of the seam welding machine 51 can be precisely adjusted in the front-back or up-down direction. This can cover the welding needs of most conventional workpieces, adapt to substrates and covers of different sizes and thicknesses without changing special tooling, reduce equipment adaptation costs and changeover time, and ensure that the roller electrode 511 fits perfectly with the weld, so that the welding current and pressure are evenly distributed, reducing welding defects such as incomplete welding and missing welding, and improving the sealing performance and structural strength of the weld.

[0068] It is understood that there are various types of first packaged drive structure 522 and second packaged drive structure 532, which can be drive cylinder, drive hydraulic cylinder, or a combination of drive motor and ball screw structure, etc. The embodiments of this application do not limit this.

[0069] In one embodiment of this application, please refer to [the relevant documentation]. Figures 3 to 5Two seam welding machines 51 are arranged at intervals along a front-to-back direction, so that the two roller electrodes 511 are set in parallel to simultaneously weld two opposite seams. During encapsulation, the two seam welding machines 51 start synchronously. The parallel roller electrodes 511 simultaneously apply pressure and pulsed current to the two opposite seams of the workpiece. The heat generated by the current through the contact resistance melts the metal at the contact point to form a weld point. As the roller electrodes 511 roll, adjacent weld points overlap, ultimately completing the welding of the two opposite seams synchronously. This eliminates the need to weld the two seams sequentially, significantly shortening the welding cycle. It also ensures that the welding parameters of the two seams are completely consistent, avoiding weld quality differences caused by temperature variations during separate welding. Thus, by using parallel double-seam welding machines 51, welding time can be significantly shortened, especially suitable for encapsulating rectangular workpieces with opposite seams, helping to improve the equipment's mass production capacity. Furthermore, it ensures that the welding current, pressure, speed, and other parameters of the two opposite seams are completely consistent, avoiding weld quality differences caused by changes in equipment status or environment during separate welding, and improving the consistency of the finished product.

[0070] In one embodiment of this application, please refer to Figure 2 , Figure 6 and Figure 7 The feeding assembly 3 includes a feeding box 31 and a transfer structure 32. The feeding box 31 is disposed in a sealed cavity for storing trays 8. The transfer structure 32 is mounted on the mounting base 11 for removing or inserting trays 8. The feeding box 31 serves as a storage container, capable of holding one or more stacked trays 8, each tray 8 bearing multiple substrates or covers. The transfer structure 32 is used to remove trays 8 from inside the feeding box 31 to an external material-receiving station, or to move empty trays 8 that have been depleted from the external station back into the feeding box 31. When a workpiece needs to be supplied to the transfer assembly 4, the transfer structure 32 operates, extending into the feeding box 31 to dock with the corresponding tray 8. The tray 8, filled with substrates or covers, is pulled from the storage position to the retrieval position. The transfer assembly 4 then picks up a single substrate or cover from the tray 8 at that position. After all the workpieces on the tray 8 have been removed, the transfer structure 32 pushes the empty tray 8 or the tray 8 containing finished products back into the feeding box 31. Thus, through the cooperation of the feeding box 31 and the transfer structure 32, automatic material entry and exit management in a sealed environment can be achieved, avoiding damage to the sealed environment and efficiency loss caused by frequent manual intervention. It also provides a fundamental guarantee for long-term unattended continuous automated production, thereby significantly improving the overall operating efficiency of the equipment.

[0071] Further, please refer to Figures 6 to 8The transfer structure 32 includes a slide rail 321, a first transfer seat 322, a second transfer seat 323, and a transfer pin 324. The first transfer seat 322 is movably mounted on the slide rail 321 in a front-to-back direction, and the second transfer seat 323 is movably mounted on the first transfer seat 322 in a vertical direction. The transfer pin 324 is fixedly mounted on the second transfer seat 323 and is correspondingly inserted into the mating hole of the material tray 8. The first transfer seat 322 moves back and forth along the slide rail 321, driving the entire mechanism to a position aligned with the material tray 8 in the feeding box 31. Then, the second transfer seat 323 moves downward, allowing the transfer pin 324 to accurately insert into the mating hole of the material tray 8, achieving mechanical locking. Subsequently, the first transfer seat 322 moves in the reverse direction, transferring the mechanism carrying the material tray 8 to the target position. Finally, the second transfer seat 323 rises, the transfer pin 324 exits the hole, and the material tray 8 is released to the target position. After processing is completed, the reverse action is performed to move the material tray 8 back to the feeding box 31. In this way, the transfer method using the guide rail 321 and the pin hole engagement can not only ensure the positional accuracy of the material tray 8 during the transfer process and prevent the material tray 8 from slipping or shifting under inertia, but also make the structure compact and the operation reliable. It can adapt to the limited space layout in the sealed cavity and ensure the smooth and accurate feeding process.

[0072] It should be noted that the transfer structure 32 also includes a first transfer drive structure and a second transfer drive structure. The first transfer drive structure is connected to the first transfer seat 322, and the second transfer drive structure is connected to the second transfer seat 323. Thus, by setting the first transfer drive structure to drive the first transfer seat 322 to move in the front-back direction, and by setting the second transfer drive structure to drive the second transfer seat 323 to move in the up-down direction, the transfer pin 324 can be inserted into the mating hole of the tray 8, and the tray 8 can be moved in the front-back direction. It is understood that the first transfer drive structure and the second transfer drive structure can be various, such as a drive cylinder, a drive hydraulic cylinder, or a combination of a drive motor and a ball screw structure. The embodiments of this application do not limit this.

[0073] In one embodiment of this application, the feed box 31 can be fixed or movable; this embodiment does not limit the specific configuration. For details, please refer to the following documentation. Figure 6 and Figure 8The feeding box 31 is movably mounted on the mounting base 11 in the vertical direction. The feeding assembly 3 also includes a feeding drive structure 311 that drives the feeding box 31 to move vertically. When the upper tray 8 is removed by the transfer structure 32, the feeding drive structure 311 will drive the entire feeding box 31 to rise upward by the thickness of one tray 8, so that the lower tray 8 rises to a fixed picking height (usually flush with the operating plane of the transfer structure 32), waiting to be picked up again. This process is repeated until all the trays 8 in the box are picked up, so that the transfer structure 32 can perform the tray picking operation at the same height position each time, which helps to simplify its motion control logic. Thus, by driving the feeding drive structure 311 to lift the feeding box 31 as a whole, the feeding box 31 can be compatible with multi-layer material racks or spring clip feeding methods, greatly increasing the storage capacity of a single feeding and reducing the frequency of downtime for material replenishment. At the same time, in conjunction with the fixed-height transfer structure 32, it helps to simplify the design complexity of the horizontal transmission mechanism, thereby improving the flexibility and adaptability of the feeding system.

[0074] In one embodiment of this application, please refer to Figure 2 The feeding assembly 3 also includes a feeding cover 33 disposed on the mounting base 11, and a feeding box 31 disposed inside the feeding cover 33. Thus, by setting the feeding cover 33, the installation position of the feeding box 31 can be positioned within the sealed cavity, serving as a limit and guide, and the disturbance of lightweight cover materials caused by gas flow within the sealed cavity can be reduced to a certain extent, helping to maintain the neat arrangement and temperature stability of the materials, thereby improving the yield of subsequent material handling and welding.

[0075] In one embodiment of this application, please refer to Figure 9 and Figure 10Each material transfer component 4 includes a first material transfer structure 41 and a second material transfer structure 42. The first material transfer structure 41 includes a first material transfer seat 411 and a first material transfer drive structure 412. The first material transfer seat 411 is movably installed on the mounting base 11 in the left-right direction. The first material transfer drive structure 412 is driven and connected to the first material transfer seat 411. The second material transfer structure 42 includes a second material transfer seat 421 and a second material transfer drive structure 422. The second material transfer seat 421 is movably installed on the first material transfer seat 411 in the up-down direction. The second material transfer drive structure 422 is driven and connected to the second material transfer seat 421. A material transfer picking structure 43 is provided on the second material transfer seat 421 for picking up the base or cover. The first material transfer drive structure 412 drives the first material transfer seat 411 to move left and right, causing the second material transfer structure 42 and the material transfer pickup structure 43 to adjust their positions left and right synchronously, accurately aligning with the feeding component 3 or the positioning table 21. The second material transfer drive structure 422 drives the second material transfer seat 421 to move up and down, causing the material transfer pickup structure 43 to adjust its height up and down, realizing the picking up and placement of materials. The material transfer pickup structure 43 selects an appropriate pickup method according to the characteristics of the substrate or cover, ensuring stable material picking, so that the material transfer component 4 can accurately cover the transfer path from the feeding point to the positioning table 21, improving the accuracy of material transfer and preventing the material from shifting or falling during the transfer process. Thus, by setting the first material transfer structure 41 and the second material transfer structure 42, the position of the material transfer picking structure 43 can be adjusted in the left-right and up-down directions. This can not only adapt to the feeding components 3 and positioning stage 21 with different spacings, but also meet the material transfer requirements of different specifications without major adjustments to the equipment structure. It can also ensure that the substrate and cover can be accurately placed in the designated position of the positioning stage 21, laying the foundation for subsequent precise welding and reducing packaging defects caused by material transfer deviation.

[0076] Further, please refer to Figure 9The two material transfer and pickup structures 43 include a first material transfer and pickup structure 431, which includes a first material transfer and pickup seat 4311, a first material transfer and pickup drive structure 4312, and two first material transfer and pickup parts 4313. The first material transfer and pickup seat 4311 is rotatably arranged about an axis extending left and right. The first material transfer and pickup drive structure 4312 is located on a second material transfer seat 421 and is driven to connect to the first material transfer and pickup seat 4311. The two first material transfer and pickup parts 4313 are installed on the first material transfer and pickup seat 4311 and are spaced apart circumferentially along the first material transfer and pickup seat 4311. When the material transfer assembly 4 moves above the tray 8, one of the downward-facing pickup parts descends synchronously to pick up a new substrate. Then the material transfer assembly 4 moves above the processing table. At this time, another pickup part, which may have previously been facing upward or to the side, rotates to face downward, descends, and picks up the finished product that has been welded on the table. Subsequently, the first material transfer and pickup drive structure 4312 drives the rotating seat to rotate, causing the pickup part carrying the new substrate to turn downwards and place the new substrate onto the vacated processing table; simultaneously, the pickup part carrying the finished product turns away from downwards. Finally, the material transfer assembly 4 can transfer the finished product to the material collection tray 8 at the feeding assembly 3. In this way, the first material transfer and pickup drive structure 4312 drives the first material transfer and pickup seat 4311 to rotate around the left-right axis, so that the two first material transfer and pickup parts 4313 can alternately be in working positions. In actual operation, one pickup part can be used to pick up the substrate to be processed, and the other pickup part can be used to pick up the finished product. In order to quickly complete the removal of the finished product and the placement of the raw material at the same station through the rotation of the first material transfer and pickup seat 4311, the loading and unloading cycle can be greatly optimized, the number of reciprocating movements of the material transfer assembly 4 can be reduced, and the seamless connection of the picking and placing actions can be achieved, thereby helping to greatly improve the working efficiency of the substrate transfer process. It is understood that the first material picking unit 4313 can pick up materials in various ways, such as negative pressure adsorption or magnetic adsorption, and the embodiments of this application do not limit this.

[0077] In one embodiment of this application, please refer to Figure 10The two material transfer pickup structures 43 include a second material transfer pickup structure 432, which includes a second material transfer pickup seat 4321 and a second material transfer pickup part 4322. The second material transfer pickup seat 4321 is mounted on the second material transfer seat 421, and the second material transfer pickup part 4322 is rotatably mounted on the second material transfer pickup seat 4321 about an axis extending vertically. When the material transfer assembly 4 picks up the cover, it passes the second camera device 72 along its path towards the positioning stage 21. The second camera device 72 takes a picture of the cover on the second material transfer pickup part 4322, and the image processing system identifies the deviation between the actual angle and the desired angle of the cover. Subsequently, the control system immediately drives the second material transfer pickup part 4322 to rotate by a corresponding compensation angle, so that the orientation of the cover is precisely calibrated before it reaches above the positioning stage 21, ensuring precise alignment with the packaging window on the substrate before placement. Thus, by employing a rotatable second material transfer pickup unit 4322, the alignment accuracy between the cover and the substrate can be improved, effectively compensating for minor angular deviations generated during material feeding or transfer, ensuring that the cover is accurately installed on the substrate, and providing a good foundation for subsequent welding. Furthermore, the second material transfer pickup structure 432 also includes a second material transfer pickup drive structure 4323 disposed on the second material transfer pickup seat 4321. The second material transfer pickup drive structure 4323 is drively connected to the second material transfer pickup unit 4322 to drive the second material transfer pickup unit 4322 to rotate.

[0078] The second material picking unit 4322 can pick up materials in various ways, such as negative pressure adsorption or magnetic adsorption, etc. The embodiments of this application do not limit this method. Specifically, in this embodiment, please refer to... Figure 10 The second material transfer and pickup unit 4322 includes a pickup straw 4322a and a rotary joint 4322b that are interconnected. The pickup straw 4322a is used to pick up the cover, and the rotary joint 4322b has a fixed end and a rotating end. The rotating end is connected to the pickup straw 4322a, and the fixed end is used to connect to an air source. When the second material transfer and pickup unit 4322 is driven to rotate to adjust the angle of the cover, the rotating ends of the pickup straw 4322a and the rotary joint 4322b rotate accordingly, while the fixed end of the rotary joint 4322b and the external air supply line connected thereto remain stationary. This allows the vacuum suction force to be continuously and leak-free transmitted from the fixed air path to the rotating straw through the rotary joint 4322b, thereby maintaining reliable adsorption of the cover at any angle of rotation of the pickup unit. Thus, by setting the rotary joint 4322b and the pick-up suction tube 4322a, interference between the rotation action and the vacuum supply can be avoided, ensuring that the cover will not fall or shift due to suction fluctuations during high-speed rotation and alignment, thereby significantly improving the reliability and safety of the equipment operation.

[0079] In one embodiment of this application, please refer to Figure 5 and Figure 11 The positioning mechanism 2 also includes a first positioning structure 22 and a second positioning structure 23. The first positioning structure 22 includes a first positioning seat 221 and a first positioning drive structure 222. The first positioning seat 221 is movably mounted on the mounting base 11 in the left-right direction. The first positioning drive structure 222 is driven and connected to the first positioning seat 221. The second positioning structure 23 includes a second positioning seat 231 and a second positioning drive structure 232. The second positioning seat 231 is movably mounted on the first positioning seat 221 in the front-back direction. The second positioning drive structure 232 is driven and connected to the second positioning seat 231. The positioning platform 21 is rotatably mounted on the second positioning seat 231 about an axis extending in the up-down direction. The first positioning drive structure 222 drives the first positioning seat 221 to move left and right, thereby adjusting the position of the second positioning structure 23 and the positioning stage 21. The second positioning drive structure 232 drives the second positioning seat 231 to move back and forth, thereby adjusting the position of the positioning stage 21. The positioning stage 21 can rotate around its vertical axis to adjust the angle of the workpiece placed on it, so that the workpiece can be accurately positioned to the optimal welding position, ensuring that the weld seam is precisely aligned with the roller electrode 511 of the seam welding machine 51, greatly improving the positioning accuracy of the workpiece, adapting to workpieces of different specifications and shapes, and reducing positioning errors. In this way, not only can precise centering correction be achieved, but it can also flexibly meet the packaging requirements of components of various sizes and shapes. At the same time, through the rotation of the workpiece, only two sets of parallel welding wheels are needed to complete the full-circumference airtight seam welding, thereby helping to simplify the structure of the packaging mechanism 5.

[0080] Further, please refer to Figure 11 The positioning mechanism 2 also includes a positioning clamping structure 24, which includes a positioning reference part 241 and a positioning clamping part 242 arranged horizontally at intervals. The positioning reference part 241 is mounted on the positioning table 21 to position the substrate. The positioning clamping part 242 is movably mounted on the positioning table 21 horizontally to hold the substrate against the positioning reference part 241. When the material transfer assembly 4 roughly places the substrate onto the positioning table 21, the initial position is determined with reference to the positioning reference part 241. The positioning clamping part 242 drives the substrate to move towards the positioning reference part 241 to hold and fix the substrate against it. The cooperation of the two restricts the horizontal displacement of the substrate. Thus, this clamping method can adapt to substrates of different sizes, and the clamping process is stable and will not damage the substrate, ensuring that the substrate maintains a precise position throughout the welding process.

[0081] In one embodiment of this application, please refer to Figure 11The positioning stage 21 has a first fixing hole, and the positioning reference part 241 has a second fixing hole. The positioning clamping structure 24 also includes fixing bolts passing through the first and second fixing holes. At least one of the first and second fixing holes is a strip-shaped hole, allowing the position of the positioning reference part 241 to be adjusted horizontally. When it is necessary to adapt to substrates of different specifications, the fixing bolts are loosened, the positioning reference part 241 is moved along the extension direction of the strip-shaped hole, and after adjusting to a position matching the current substrate, the fixing bolts are tightened again to complete the fixation. The operation is convenient and the adjustment accuracy is high, which can quickly adapt to the positioning requirements of substrates of different sizes. In this way, by setting the strip-shaped hole, the positioning stage 21 can adapt to the packaging requirements of more substrate specifications, significantly reducing the application threshold of the equipment.

[0082] In one embodiment of the application, please refer to Figure 11 Two positioning clamping structures 24 are provided, one of which is arranged in the left-right direction and the other in the front-back direction. Thus, the positioning clamping structure 24 arranged in the left-right direction can limit the displacement of the substrate in the left-right direction, and the positioning clamping structure 24 arranged in the front-back direction can limit the displacement of the substrate in the front-back direction. Together, they form an all-round horizontal limiting effect, significantly improving positioning stability compared to single-direction clamping. Furthermore, its adaptability to regular-shaped substrates such as rectangles makes positioning more precise, helping to further reduce welding deviations.

[0083] In one embodiment of this application, please refer to Figure 4 The seam welding and packaging equipment 100 also includes a waste gas recirculation mechanism 6, which includes a circulation pipeline and a filter device. One end of the circulation pipeline is located on the mounting base 11 and corresponds to the positioning platform 21, while the other end connects to the sealed cavity. The filter device is located on the circulation pipeline. During the welding process, the instantaneous high temperature generated by the contact resistance may cause the metal plating to volatilize, producing fumes or trace amounts of waste gas. Therefore, the waste gas generated in the welding area is drawn in through the circulation pipeline, filtered to remove particulate matter and harmful impurities, and then the purified gas is returned to the sealed cavity to maintain pressure balance within the cavity. Thus, by setting up the waste gas recirculation mechanism 6, welding fumes can be promptly removed, preventing them from contaminating the surface of components or affecting the detection accuracy of the optical vision system. Furthermore, the gas can be recycled while maintaining the purity of the inert gas within the sealed cavity, significantly reducing the cost of inert gas consumption and thus helping to ensure the cleanliness of the process environment.

[0084] In one embodiment of this application, please refer to Figures 2 to 4The seam welding and packaging equipment 100 includes a first camera device 71 and a second camera device 72. The first camera device 71 is positioned above the positioning platform 21 to acquire the orientation of the substrate on the positioning platform 21, while the second camera device 72 is positioned on the mounting base 11 to acquire the orientation of the cover. The first camera device 71 photographs the substrate on the positioning platform 21 and transmits the orientation information to the control system. The control system adjusts the angle of the positioning platform 21 or the movement of the material transfer mechanism based on the information to ensure accurate substrate positioning. The second camera device 72 photographs the cover and, after acquiring its orientation information, the control system adjusts the angle of the material transfer and picking structure 43 to precisely align the cover with the substrate. This allows for real-time compensation of deviations during material feeding or transfer, improving assembly accuracy. Thus, by using the first camera device 71 and the second camera device 72, the alignment accuracy between the substrate and the cover can be significantly improved, effectively compensating for minor deviations during material feeding and transfer, avoiding welding defects caused by misalignment, and contributing to improved product quality.

[0085] In one embodiment of this application, the seam welding packaging equipment 100 further includes a vacuum device and a gas filling device disposed in the housing 1. The vacuum device is connected to the sealed cavity and is used to extract gas from the sealed cavity. The gas filling device is connected to the sealed cavity and is used to inject inert gas into the sealed cavity. Specifically, before packaging begins, the vacuum device is used to evacuate the sealed cavity to a vacuum state, and then the gas filling device is used to refill it with high-purity inert gas, bringing the cavity to a slightly positive pressure state. Thus, by setting up the vacuum device and the gas filling device, oxidation and corrosion of the internal chips and circuits of electronic components are prevented after packaging, ensuring that the packaged components can meet stringent airtightness standards and long-term reliability requirements.

[0086] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
