Description

Technical Field

[0001] This utility model belongs to the technical field of die bonding equipment, specifically relating to a soldering station module. Background Technology

[0002] Die bonding equipment, also known as a chip mounter, is commonly used in the silicon carbide (SiC) chip mounting field. Currently, nano-silver is generally used as the bonding layer between the chip and the substrate. During the silicon carbide chip mounting process, the bonding station and the mounting head are usually heated to help achieve pre-sintering. However, nano-silver is relatively easy to oxidize, and it is even more prone to oxidation after heating. Once oxidized, it will affect the quality of the chip mounting, which in turn will affect subsequent processes and lead to the generation of waste products.

[0003] A soldering station module is a component of a die bonding device. It is used to solder chips onto a chip substrate. This invention provides a novel soldering station module to meet current production needs in the field. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a soldering station module, which has an outer cover fixed to the outside of the base and an anti-oxidation gas introduced into the outer cover. The nitrogen environment does not mix with the air environment, and a very high nitrogen density can be achieved.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A soldering station module includes: a soldering station assembly, a first direction drive assembly, and a second direction drive assembly disposed within the outer casing;

[0007] The second direction drive component is fixedly mounted on the base of the die bonding device. The first direction drive component is driven by the second direction drive component. The second direction drive component is used to drive the first direction drive component to move along the second direction. The first direction drive component is driven by the soldering station component and is used to drive the soldering station component to move in the first direction.

[0008] Furthermore, the welding station assembly includes a surrounding shell, a welding station plate, a welding station base, a welding station sealing assembly, and a lifting rail assembly. A welding station upright plate is fixed to the upper part of the welding station base. The welding station upright plate is fixed to the lower part of the welding station plate and distributed around the welding station plate. The surrounding shell surrounds the welding station upright plate and is fixedly connected to the welding station base.

[0009] There are two welding station sealing assemblies, each installed on the welding station base. The welding station sealing assemblies are located on both sides of the welding station upright plate and in the second direction of the base. The lifting rail assembly is installed on the welding station base and is used to transport the material. The lifting rail assembly is located in the first direction of the base.

[0010] Furthermore, the welding station sealing assembly includes a sealing cylinder and a sealing plate disposed on the third direction of the base. The sealing cylinder is fixed to one side of the welding station base, and the sealing plate is connected to the output end of the sealing cylinder. The length of the sealing plate matches the length of the groove opened in the surrounding shell, so that the sealing plate can cooperate with the surrounding shell and the outer cover to form a sealing structure after being raised.

[0011] Furthermore, the lifting track assembly includes a track plate, a lifting upright plate, a lifting track cylinder, and a lifting spring. The track plate is distributed in the first direction of the base and located on one side of the welding station plate. Two parallel lifting track slides are slidably connected to one side of the track plate. The lifting track slides are slidably connected to the lifting track slide rail fixed on the lifting upright plate. The lifting upright plate is fixed on the welding station base.

[0012] The lifting spring is installed at the lower part of the opening in the middle of the lifting plate. Under the action of the lifting spring, the track plate tends to move away from the welding station. The lifting track cylinder is fixed at the upper part of the opening in the middle of the lifting plate. The output end of the lifting track cylinder abuts against the track plate, so that the track plate can move closer to the welding station after the lifting track cylinder is working.

[0013] Furthermore, the first direction drive assembly includes a welding station linear module slide and a welding station linear module mounted in the first direction. The upper part of the welding station linear module slide is fixedly connected to the welding station linear module, and the welding station linear module is drively connected to the welding station base.

[0014] The second direction drive assembly includes a soldering station drive base, a soldering station drive motor, and a soldering station ball screw disposed in the second direction of the base. The soldering station drive motor is connected to the soldering station ball screw, and the end of the soldering station ball screw is connected to the soldering station linear module slide.

[0015] Compared with existing technologies, the beneficial effects of this solution are:

[0016] This invention provides a soldering station module, which is mounted on a base for processing materials. The module can be purged with an anti-oxidation gas (nitrogen). An outer cover is bolted to the base, covering the rest of the module and forming a relatively enclosed processing space with the base. Compared to existing inline designs that directly purge nitrogen into the surface mount area for silicon carbide oxidation prevention, this invention's method of purging nitrogen prevents the nitrogen environment from mixing with the air, achieving a high nitrogen density and requiring less nitrogen for larger surface mount areas.

Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings.

[0035] A die bonding device, such as Figures 1-3 As shown, it includes:

[0036] A base 1, on which two slide rail devices 11 are arranged opposite each other along a second direction, and a movable crossbeam 13 is slidably installed between the two slide rail devices 11. The movable crossbeam 13 is arranged in a first direction of the base 1, and a patch head assembly 14 for patching is installed on the movable crossbeam 13.

[0037] Feeding module 2, which is disposed on the base 1 and located in the first direction;

[0038] A soldering station module 3 is located downstream of the feeding module 2, below the placement head assembly 14, and is used for processing materials; and

[0039] The discharge module 4 is located downstream of the welding station module 3 and is used to receive materials from the welding station module 3.

[0040] The base 1 is also fixed with an outer cover 5 that covers the welding station module 3. The outer cover 5 can be vented with atmospheric gas. The outer cover 5 has a patch hole and covers the material to be processed to form a closed processing space.

[0041] According to a specific embodiment of the present invention, the base 1 is horizontally arranged, the second direction is the Y-axis direction of the base 1, the first direction is the X-axis direction of the base 1, and the height direction (third direction) of the base 1 is the Z-axis direction. Two slide rail devices 11 are arranged on the upper part of the base 1 near both sides. Specifically, the slide rail device 11 can adopt the existing gantry shaft structure. The slide rail device 11 drives the moving crossbeam 13 to move in the second direction. The moving crossbeam 13 is equipped with a patch head assembly 14 for patching. The patch head assembly 14 adopts the existing structure, such as a patch head that can move in the height direction of the base 1.

[0042] One side of the base 1 is the feeding side, and the opposite side is the discharging side. The feeding side is equipped with a feeding module 2, which is used to transport materials to the soldering station module 3. The material transported by the feeding module 2 is the substrate to be processed. A chip placement stage 12 is also installed on the upper part of the base 1. Chips to be used are placed on the chip placement stage 12. When in use, the chip placement head assembly 14 picks them up and moves them to the substrate to be processed on the soldering station module 3 for chip placement.

[0043] The soldering station module 3 is mounted on the base 1 and is used to process materials. The soldering station module 3 can be vented with atmospheric gas. The discharge module 4 is mounted on the discharge side of the base 1. The discharge module 4 is used to receive the materials processed by the soldering station module 3. The soldering station module 3 includes an outer cover 5. The outer cover 5 is fixedly mounted on the base 1 with bolts around its perimeter. A patch hole is opened in the middle of the outer cover 5. The patch hole is used for the patch head assembly 14 to extend into and patch the substrate material. The outer cover 5 covers the rest of the soldering station module 3 and, together with the base 1, forms a relatively enclosed processing space.

[0044] During processing, after the soldering station module 3 heats up to the working temperature, the soldering station module 3 moves so that the position on the substrate that needs to be placed is aligned with the placement hole in the middle of the outer cover 5. Then, the placement head assembly 14 picks up the chip and places it into the placement hole for placement. After that, the soldering station module 3 aligns the next placement station on the substrate with the placement hole. The above process is repeated until the entire substrate is finished with placement.

[0045] Furthermore, such as Figures 4-8 As shown, the welding station module 3 also includes a welding station assembly, a first direction drive assembly, and a second direction drive assembly disposed within the outer cover 5;

[0046] The second direction drive component is fixedly mounted on the base 1, and the first direction drive component is in transmission cooperation with the second direction drive component. The second direction drive component is used to drive the first direction drive component to move along the second direction. The first direction drive component is in transmission connection with the soldering station component and is used to drive the soldering station component to move in the first direction.

[0047] According to a specific embodiment of the present invention, this embodiment provides a specific structure of a welding station module 3. A second direction driving component is fixedly installed on a base 1. The second direction driving component is used to drive a first direction driving component to move in a second direction. A welding component is installed on the first direction driving component. The first direction driving component is used to drive the welding station component to move in a first direction.

[0048] Furthermore, the welding station assembly includes a surrounding shell 31, a welding station plate 32, a welding station base 33, a welding station sealing assembly 34, and a lifting track assembly 35. A welding station upright plate 321 is fixed on the upper part of the welding station base 33. The welding station upright plate 321 is fixed to the lower part of the welding station plate 32 and distributed around the welding station plate 32. The surrounding shell 31 surrounds the welding station upright plate 321 and is fixedly connected to the welding station base 33.

[0049] There are two welding station sealing assemblies 34, which are respectively installed on the welding station base 33. The welding station sealing assemblies 34 are located on both sides of the welding station upright plate 321 and in the second direction of the base 1. The lifting rail assembly 35 is installed on the welding station base 33 and is used to transport the material. The lifting rail assembly 35 is located in the first direction of the base 1.

[0050] According to a specific embodiment of the present invention, the ambient gas in this embodiment is nitrogen, the surrounding shell 31 is a frame structure, a nitrogen inlet hole is opened on the outside of the surrounding shell 31, the soldering plate 32 is a rectangular flat plate structure, and the soldering plate 321 is not limited to its specific structure in this embodiment, as long as the soldering plate 32 can be installed on the soldering base 33.

[0051] The welding station plate 32 is located in the middle of the surrounding shell 31, and welding station upright plates 321 are fixed to the lower part of the welding station plate 32. The welding station base 33 is equipped with a welding station sealing component 34 on the side in the direction of material input and output. The welding station sealing component 34 isolates the welding space from the external environment in the second direction of the welding station plate 32. The lifting rail component 35 is installed on the welding station base 33 and is correspondingly set with the feeding module 2. The lifting rail component 35 is used to dock the material from the feeding module 2 and form a limit. The lifting rail component 35 is raised and the welding station sealing component 34 is lowered to wait for the material to enter the welding station module 3. When the material enters the welding station module 3, the lifting rail component 35 is lowered to place the material (substrate) on the welding station plate 32. At this time, the welding station sealing component 34 is raised, which, together with the outer cover 5, isolates the welding station from the external environment.

[0052] Furthermore, the welding station sealing assembly 34 includes a sealing cylinder 36 and a sealing plate 37 disposed on the third direction of the base 1. The sealing cylinder 36 is fixed to one side of the welding station base 33, and the output end of the sealing cylinder 36 is connected to the sealing plate 37. The length of the sealing plate 37 matches the length of the groove opened in the surrounding shell 31, so that the sealing plate 37 can cooperate with the surrounding shell 31 and the outer cover 5 to form a sealing structure after being raised.

[0053] According to a specific embodiment of the present invention, the sealing cylinder 36 is installed vertically. The sealing cylinder 36 adopts a sliding cylinder 452. The surrounding shell 31 has a groove to allow material to pass through. The sealing plate 37 has an "L" shaped plate structure in cross-section. One side is fixed to the output end of the sealing cylinder 36, and the other side is close to the welding station and located in the groove of the surrounding shell 31.

[0054] Furthermore, the lifting track assembly 35 includes a track plate 351, a lifting upright plate 352, a lifting track cylinder 353, and a lifting spring (not visible in the figure). The track plate 351 is distributed in the first direction of the base 1 and located on one side of the welding station plate 32. Two parallel lifting track slides are slidably connected to one side of the track plate 351. The lifting track slides are slidably connected to the lifting track slide rail fixed on the lifting upright plate 352. The lifting upright plate 352 is fixed on the welding station base 33.

[0055] The lifting plate 352 has a lifting spring installed at the lower part of the opening in the middle. Under the action of the lifting spring, the track plate 351 tends to move away from the welding station 33. The lifting track cylinder 353 is fixed at the upper part of the opening in the middle of the lifting plate 352. The output end of the lifting track cylinder 353 abuts against the track plate 351, so that the track plate 351 can move closer to the welding station 33 after the lifting track cylinder 353 is working.

[0056] According to a specific embodiment of the present invention, the track plate 351 is a long strip plate structure. The track plate 351 is provided with a groove structure for the substrate to enter. The track plate 351 is provided with a chamfer structure in the feeding direction to facilitate the entry of materials, thereby forming a limiting function.

[0057] The lifting track slide is slidably connected to the lifting track slide rail on the lifting plate 352, allowing the track plate 351 to move vertically. The lifting plate 352 is vertically fixed on the welding station base 33. The lifting track slide rail is fixed on the side of the lifting plate 352 facing the welding station plate 32. The lifting plate 352 has an opening in the middle, and a lifting spring (not visible in the figure) is installed at the lower part of the opening. The lifting track cylinder 353 is fixed in the middle of the opening. The track plate 351 is equipped with an abutment block 354, which extends into the opening in the middle of the lifting plate 352. The lifting spring is located at the lower part of the abutment block 354. The lifting spring is a compression spring. Under the action of the lifting spring, the track plate 351 can be lifted. The output end of the lifting track cylinder 353 abuts against the side of the abutment block 354. In this way, when the lifting track cylinder 353 works, it can push the abutment block 354 to move the track plate 351 down, so that the material is placed on the welding station plate 32.

[0058] Furthermore, the first direction drive assembly includes a sliding block 38 for a welding station linear module 381 and a welding station linear module 381 mounted in the first direction. The upper part of the sliding block 38 for the welding station linear module 381 is fixedly connected to the welding station linear module 381, and the welding station linear module 381 is drively connected to the welding station base 33.

The soldering station linear module 381 slide block 38 slides with the two slide rails. The soldering station linear module 381 is fixed to the upper part of the soldering station linear module 381 slide block 38.

[0061] Furthermore, such as Figures 9-11As shown, the feeding module 2 includes a feeding conveyor belt assembly 21 and a feeding pusher assembly 22 mounted on the base 1. The feeding pusher assembly 22 includes a pusher cylinder 26, a feeding deflector plate 23, and a pressing component. The pusher cylinder 26 is arranged along the material movement direction and is fixed on the feeding pusher plate 27. The feeding pusher plate 27 is fixedly mounted on the feeding conveyor belt assembly 21. The output end of the pusher cylinder 26 is rotatably mounted on the feeding deflector plate 23. Under the drive of the pusher cylinder 26, the feeding deflector plate 23 can move along the first direction of the base 1.

[0062] The pressing component is fixed in the middle of the feeding pusher plate 27, so that when the feeding pusher plate 23 moves to the pressing component, the feeding pusher plate 23 can abut against the pressing component and rotate at a certain angle.

[0063] According to a specific embodiment of this utility model, the feeding conveyor belt assembly 21 is fixed on the base 1. The feeding conveyor belt assembly 21 can adopt an existing conveyor belt structure, and the feeding conveyor belt assembly 21 is set according to the width of the substrate.

[0064] The feeding pusher plate 27 has a long plate structure, and a pusher cylinder 26 is installed on the feeding pusher plate 27. The pusher cylinder 26 is an existing rodless cylinder, which can be the CY3B rodless cylinder manufactured by SMC. The pusher cylinder 26 is fixedly installed on the feeding pusher plate 27 along the length of the feeding conveyor belt assembly 21. The feeding deflector 23 is rotatably mounted on the output end of the pushing cylinder 26 via the deflector connecting plate 28. The feeding deflector 23 has an "N"-shaped hook structure and is rotatably mounted on the deflector connecting plate 28. A deflector spring 281 is installed on the deflector connecting plate 28. One side of the feeding deflector 23 abuts against one end of the deflector spring 281, and the other end of the deflector spring 281 is fixedly mounted on the spring plate 282. The deflector spring 281 is a compression spring. Under the action of the deflector spring 281, the end of the feeding deflector 23 can be set upward so that the upper end of the feeding deflector 23 can be inserted into the lower edge of the material (the edge of the material tray). Driven by the pushing cylinder 26, the feeding deflector 23 can move along the first direction of the base 1, thereby moving the material to the welding plate 32 of the welding station module 3.

[0065] Further, the pressing component includes a pressing seat 24 and a lever 25 fixed on the pressing seat 24. The pressing seat 24 is fixed to the middle of the feeding pusher plate 27, and extends away from the feeding pusher plate 27 to form an installation structure. The lever 25 is fixed at the installation structure, and the lever 25 is horizontally positioned and extends above the pushing cylinder 26. To facilitate the feeding pusher plate 23 extending under the material, the pressing component is fixed in the middle of the feeding pusher plate 27. When the pushing cylinder 26 drives the feeding pusher plate 23 to move to the pressing component, the feeding pusher plate 23 can abut against the pressing component and rotate at a certain angle. Specifically, the pressing seat 24 is fixed to the middle of the feeding pusher plate 27, and the pressing seat 24 extends in the height direction to form an installation structure. The lever 25 is horizontally positioned and extends above the pushing cylinder 26, corresponding to the feeding pusher plate 23.

[0066] Furthermore, such as Figures 12-15 As shown, the discharge module 4 includes a discharge conveyor belt assembly 41 and a discharge pushing assembly 42 installed on the base 1. The discharge pushing assembly 42 includes a discharge motor 43, a discharge timing belt 44, a discharge timing assembly 45, and a discharge fixing plate 46.

[0067] The discharge fixing plate 46 is fixedly installed on the discharge conveyor belt assembly 41. The discharge motor 43 is installed at one end of the discharge fixing plate 46. The discharge synchronous belt 44 is arranged along the material movement direction and is connected to the discharge motor 43. The discharge synchronous component 45 is fixed on the upper part of the discharge synchronous belt 44. The discharge synchronous component 45 is slidably connected to the discharge slide rail on the discharge fixing plate 46. The discharge synchronous component 45 is fixed with a discharge deflector plate 481. The discharge deflector plate 481 is used to push out the processed material. Under the drive of the discharge motor 43, the discharge synchronous component 45 can move along the first direction of the base 1.

[0068] According to a specific embodiment of this utility model, the discharge conveyor belt assembly 41 is fixed on the base 1. The discharge conveyor belt assembly 41 can adopt an existing conveyor belt structure, and its position on the substrate is set accordingly. In order to facilitate the better removal of the processed material from the soldering station plate 32, this embodiment provides a specific structure for the discharge pushing assembly 42, which is installed between the discharge conveyor belt assemblies 41 and located below the material passing through.

[0069] The discharge fixing plate 46 is fixedly installed inside the discharge conveyor belt assembly 41. The discharge fixing plate 46 adopts a long plate seat structure to facilitate the installation of the discharge timing belt 44. The discharge fixing plate 46 is equipped with a discharge motor 43 at the material inlet end. The discharge timing belt 44 has a structure with a limiting tooth on one side. The discharge timing belt 44 is fixedly installed with the discharge timing assembly 45 through the limiting tooth. The other end of the discharge fixing plate 46 is equipped with a timing pulley 47. The discharge timing belt 44 and the timing pulley 47 rotate and cooperate. In this way, when the discharge motor 43 is working, it drives the discharge timing assembly 45 to move through the discharge timing belt 44. The upper part of the discharge timing assembly 45 is equipped with a discharge deflector plate 481. The discharge deflector plate 481 has a finger-shaped structure. One end of the discharge deflector plate 481 extends upward. The discharge deflector plate 481 can remove the material from the welding station plate 32 and then continue to output forward through the discharge conveyor belt assembly 41.

[0070] Furthermore, the discharge synchronization component 45 includes a discharge synchronization seat 451 fixedly connected to the discharge synchronization belt 44, a slide cylinder 452, and a discharge overload detection component;

[0071] The slide cylinder 452 is fixed on the discharge synchronization seat 451. The output end of the slide cylinder 452 is fixed with a slide output seat 453. The slide output seat 453 is fixed with the discharge overload detection component. The discharge overload detection component is fixedly installed with the discharge baffle 481. The slide cylinder 452 is used to drive the discharge overload detection component to move upward in the third direction.

[0072] According to a specific embodiment of this utility model, the discharge timing belt 44 operates under the drive of the discharge motor 43. Simultaneously, the discharge timing belt 44 drives the discharge timing seat 451 to move along the discharge slide rail. The slide cylinder 452 is installed in the height direction, allowing the discharge deflector plate 481 to move in the height direction, thus facilitating the insertion of the discharge deflector plate 481 into the corresponding position on the substrate material platform, thereby pulling or pushing the substrate material platform forward. The slide output seat 453 is fixed with a discharge overload detection component. When the substrate material platform is obstructed or jammed during movement, the discharge overload detection component detects this process and transmits a signal to the electrical control system. The electrical control system then sends a signal to stop the discharge motor 43.

[0073] Specifically, the discharge overload detection component includes a pushing detection structure and a pulling detection structure. A first slide rail 457 is installed on the slide output seat 453. The first slide rail 457 is slidably connected to the pushing detection structure. The discharge baffle 481 is fixed on the pulling detection structure.

[0074] The material pushing detection structure includes a material pushing spring and a material pushing sensor 454. The material pulling detection structure is slidably connected to the first slide rail 457. The material pushing sensor 454 is mounted on the slide output seat 453. Under the action of the material pushing spring, the material pulling detection structure tends to move away from the material pushing sensor 454. The material pushing spring is not visible in the figure.

[0075] The material pulling detection structure includes a material pulling detection base 455, a material pulling spring, and a material pulling sensor 456. A first slide rail 457 is slidably connected to the material pulling detection base 455. A second slide rail is fixedly installed on the material pulling detection base 455. A dial plate mounting seat 48 is slidably connected to the second slide rail. The material pulling sensor 456 is installed on the material pulling detection base 455. One end of the material pulling spring abuts against the material pulling detection base 455, and the other end abuts against the dial plate mounting seat 48. Under the action of the material pulling spring, the dial plate mounting seat 48 tends to move away from the material pulling sensor 456. The material pulling spring is not visible in the figure.

[0076] The push detection structure and pull detection structure can be used to detect when the substrate material stage is obstructed or jammed during the push and pull processes, respectively. The second slide guide rail and the first slide guide rail 457 adopt a linear guide rail structure. The push spring and the pull spring are both compression springs. The pull detection base 455 and the dial plate mounting base 48 are not limited in their specific structures. The push sensor 454 and the pull sensor 456 are both photoelectric sensors. Light blocking plates are installed on the pull detection base 455 and the dial plate mounting base 48. After the pull detection base 455 and the dial plate mounting base 48 move against the push spring or the pull spring, the light blocking plates are inserted into the push sensor 454 and the pull sensor 456 respectively to generate signals.

[0077] The specific working process is as follows: The chip substrate material enters the feeding conveyor assembly 21 from the left side of the die bonding device. At this time, the soldering station module 3 will move to the corresponding position to dock with the chip substrate, and the sealing plate 37 at the feeding point on the soldering station module 3 will be in a low position, while the track plate 351 will rise. After the chip substrate is transferred through the feeding pusher plate 23 of the feeding pusher assembly 22 via the feeding conveyor assembly 21, the feeding pusher plate 23 will push the chip substrate completely into the soldering station module 3. Then, the track plate 351 will descend, allowing the chip substrate to fall onto the soldering station plate 32 for vacuuming and fixation. After that, the sealing plate 37 at the feeding point of the soldering station plate 32 will rise.

[0078] At this point, the soldering station and the outer casing 5 form a relatively sealed cavity. Nitrogen gas is then introduced into the entire outer casing 5, and the soldering station board 32 begins to heat up. Once the operating temperature is reached, the first and second direction drive components operate, aligning the chip substrate with the mounting hole in the center of the outer casing 5. The mounting head then picks up the chip from the chip placement stage 12 and places it at the mounting station. The soldering station module 3 then aligns the next station of the chip substrate with the opening, repeating this process until the entire chip substrate is mounted. Once the entire chip substrate is mounted, the vacuum on the soldering station board 32 is disconnected, the track plate 351 rises, and the sealing plate 37 on the ejection side of the soldering station module 3 lowers. The ejection module 4 then hooks the chip substrate out of the soldering station module 3, and finally, with the help of the ejection conveyor assembly 41, ejects the chip substrate.
