Description

Technical Field

[0001] This invention relates to the field of ceramic copper-clad substrate technology, and more specifically to an automatic feeding system for the post-processing of ceramic copper-clad substrates in the DBC process. Background Technology

[0002] Ceramic copper-clad substrates are a special type of electronic packaging material, consisting of a ceramic substrate and two copper plates bonded together using a special process. The copper plates provide conductivity or circuit connections, while the ceramic substrate provides insulation. The DBC process is a common manufacturing process for ceramic copper-clad substrates. After sintering, a pattern is transferred onto the copper foil surface. Before the transfer, a post-processing horizontal line is required to clean the substrate surface.

[0003] The current operating mode involves manually removing the copper-clad ceramic substrate from the material box and placing it on the conveyor rollers of the post-processing horizontal line. However, during the manual feeding process, not only must the copper-clad ceramic substrates be separated one by one, but the surface of the substrate must not be scratched or contaminated. At the same time, when placing it on the horizontal line, the copper-clad ceramic substrates must be evenly arranged, and the copper-clad ceramic substrates must be in contact with the rollers before they can be released to avoid causing ceramic cracks. This highly precise and repetitive feeding process is not only labor-intensive, but also greatly tests the patience of the workers. Since the cracks in the copper-clad ceramic substrates are subtle and difficult to detect, the risk of hidden damage such as cracks in the copper-clad ceramic substrates during the manual feeding process is completely uncontrollable.

[0004] Based on the above background, the inventors designed an automatic feeding system for the post-processing of the DBC process of ceramic copper-clad substrates, which solves at least one of the above problems, and thus, this application is filed. Summary of the Invention

[0009] Optionally, the flipping assembly further includes a flipping drive motor and a flipping transmission structure; The flipping drive motor, the flipping transmission structure, and the flipping shaft are all mounted on the lifting bracket. The flipping drive motor drives the flipping shaft to rotate around its central axis on the lifting bracket through the flipping transmission structure. The flip drive motor is a servo motor or a stepper motor.

[0010] Optionally, the feeding assembly includes a horizontally arranged feeding conveyor belt; With the lifting and tilting assembly in the tilted state, the feeding end of the feeding conveyor belt is located directly below the tilted material loading box; The feeding assembly also includes a transverse sliding module and two sets of positioning rollers located on the output end of the transverse sliding module. The two sets of positioning rollers are located on both sides of the feeding conveyor belt. The sliding direction of the output end of the lateral sliding module is perpendicular to the conveying direction of the feeding conveyor belt.

[0011] Optionally, the three-axis material handling assembly includes a longitudinal linear module, a transverse linear module, a vertical linear module, and a material handling suction cup; The longitudinal linear module is provided in two sets. Both sets of longitudinal linear modules are horizontally arranged and parallel to the discharge direction of the discharge component. The feeding component and the discharge component are located between the two sets of longitudinal linear modules. The front and rear ends of the longitudinal linear module along the discharge direction extend into the middle of the feeding component and the discharge component, respectively.

[0013] Optionally, the discharge module further includes two sets of waste board storage components, which are respectively arranged on both sides of the multiple sets of discharge components; Both sets of waste board storage components are located directly below the three-axis material handling components; The waste board storage assembly includes a waste board storage box for storing defective waste boards.

[0014] Optionally, the discharge module may further include a visual recognition component disposed directly above the discharge component.

[0015] Optionally, the storage module includes a storage frame; The material box conveying assembly is provided with an even array and is configured in two layers, upper and lower; The number of lifting and tilting components and unloading components is equal to half the number of material box conveying components; When the lifting and flipping assembly is not flipped, the upper material box conveying assembly, the feeding end of the lifting and flipping assembly, the unloading assembly, and the discharging assembly are at the same horizontal height.

[0016] The beneficial effects of this invention are: This application establishes adjacent storage and loading modules. The storage module incorporates at least two layers of material box conveying assemblies with opposite conveying directions. This allows the storage module to continuously feed material plate loading boxes containing the main body of the material plate to the loading module, while simultaneously removing empty material plate loading boxes from the loading module. This enables a clockwise or counter-clockwise material plate conveying cycle within the storage module, requiring only manual loading and unloading of the material plate loading boxes. The loading module, adjacent to the storage module, includes a lifting and tilting assembly, as well as a discharging assembly, a three-axis picking assembly, and a discharging assembly, all working in concert. After the lifting and tilting assembly removes the material plate loading box from the material box conveying assembly, it first tilts it 90 degrees, changing the material plate loading box from a horizontal to a vertical position. The material plates inserted into the material plate slots in the material plate loading box change from a vertical state to a horizontal state and are distributed in layers. The feeding end of the unloading component is located directly below the flipped material plate loading box. At this time, the lifting and flipping component only needs to drive the material plate loading box down to place the material plate bodies in the material plate loading box onto the feeding end of the unloading component. The unloading component can then transport the material plate bodies out of the material plate loading box. Each time a material plate body is transported out, the lifting and flipping component drives the material plate loading box down once, until all the material plate bodies are taken out of the material plate loading box. This completes the step-by-step transfer of the material plate bodies from the box to the loading component. Then, the three-axis picking component takes away each transferred material plate body and places it on the unloading component, thus completing the entire process of material plate body transfer.

[0017] Therefore, through the concept of mutual coordination between the material storage module and the material loading module, as well as the internal material box conveying component, lifting and flipping component, as well as the unloading component, three-axis picking component and discharge component, the entire material plate loading process of this application does not require manual operation except for picking and placing the material plate loading box. It has a high degree of automation and completely avoids the problems of high labor intensity and uncontrollable hidden damage to the material plate body caused by manual piece loading.

Detailed Implementation

[0030] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0031] like Figures 1 to 11 As shown, this application provides an automated feeding system for the post-processing of ceramic copper-clad substrates (DBC), including an adjacent storage module 1 and a feeding module 2, wherein: The storage module 1 includes at least two sets of material box conveying assemblies 11 arranged in the horizontal direction, and a material plate loading box 12 for placing on the material box conveying assembly 11; The material box conveying assembly 11 has at least two layers distributed vertically and the conveying directions are opposite; The two inner side walls of the material loading box 12 are provided with material plate slots 121 for loading material plates, and the material plate slots 121 are perpendicular to the conveying direction of the material box conveying assembly 11. The feeding module 2 includes a lifting and flipping assembly 22 for transferring the material loading box 12 and flipping it 90 degrees, as well as a feeding assembly 24, a three-axis material picking assembly 25 and a discharging assembly 26. Before the lifting and tilting assembly 22 is tilted, the feeding end of the lifting and tilting assembly 22 is located directly below the discharging end of the material box conveying assembly 11; After the lifting and tilting assembly 22 is tilted, the feeding end of the unloading assembly 24 is located directly below the tilted material loading box 12; The feeding end of the discharge component 26 is located close to the discharge end of the unloading component 24, and the three-axis material handling component 25 is located directly above the unloading component 24 and the discharge component 26.

[0032] This embodiment sets up an adjacent storage module 1 and a loading module 2. The storage module 1 has at least two layers of material box conveying assemblies 11 with opposite conveying directions. This allows the storage module 1 to continuously feed material plate loading boxes 12 containing material plate bodies 3 to the loading module 2, while the other layer continuously removes empty material plate loading boxes 12 from the loading module 2. This allows for a clockwise or counterclockwise material plate body 3 conveying cycle within the storage module 1, requiring only manual loading and unloading of the material plate loading boxes 12. The loading module 2, adjacent to the storage module 1, includes a lifting and tilting assembly 22, a unloading assembly 24, a three-axis material picking assembly 25, and a discharging assembly 26, all working in concert. After the lifting and tilting assembly 22 removes the material plate loading box 12 from the material box conveying assembly 11, it first tilts it 90 degrees, changing the material plate loading box 12 from a horizontal to a vertical position. The material plate body 3 inserted into the material plate slot 121 in the material plate loading box 12 changes from a vertical state to a horizontal state and is distributed in layers. The feeding end of the unloading component 24 is located directly below the flipped material plate loading box 12. At this time, the lifting and flipping component 22 only needs to drive the material plate loading box 12 to descend, so that the material plate body 3 in the material plate loading box 12 is placed on the feeding end of the unloading component 24. The unloading component 24 can then transport the material plate body 3 out of the material plate loading box 12. Each time a material plate body 3 is transported out, the lifting and flipping component 22 drives the material plate loading box 12 to descend once, until all the material plate bodies 3 are taken out of the material plate loading box 12. This completes the step-by-step transfer of the material plate body 3 from the box to the loading component 23. Then, the three-axis picking component 25 is used to pick up the material plate body 3 transferred out each time and place it on the unloading component 26, thus completing the entire process of transferring the material plate body 3.

[0033] Therefore, through the concept of mutual coordination between the material storage module 1 and the material loading module 2, as well as the internal material box conveying component 11, lifting and flipping component 22, material unloading component 24, three-axis material picking component 25 and material discharging component 26, the entire material plate body 3 of this application does not require manual operation except for picking and placing the material plate loading box 12. The degree of automation is high, and the problems of high labor intensity and uncontrollable hidden damage to the material plate body 3 caused by manual piece loading are completely avoided.

[0034] In this embodiment, the material box conveying assembly 11 further includes a material box conveying frame 113, and the material box conveyor belt is disposed on the material box conveying frame 113.

[0035] like Figure 6 and Figure 7 As shown, in this embodiment, the lifting and flipping assembly 22 includes a lifting module 21, a flipping assembly 22, and a feeding assembly 23 that are fixedly connected. The lifting module 21 is vertically arranged and located downstream of the material box conveying assembly 11 along its conveying direction; The lifting module 21 includes a lifting bracket 211; The flipping component 22 is fixedly connected to the lifting bracket 211. The flipping component 22 includes a horizontally arranged flipping shaft 222, which is arranged perpendicular to the conveying direction of the material box conveying component 11. The maximum rotation angle of the flipping shaft 222 is 90 degrees. The feeding component 23 is fixedly connected to the flipping shaft 222 of the flipping component 22.

[0036] In this embodiment, the lifting and flipping assembly 22 includes three cooperating components: a lifting module 21, a flipping assembly 22, and a feeding assembly 23. The lifting module 21 can drive the flipping assembly 22 and the feeding assembly 23 to move vertically. After the flipping assembly 22 flips 90 degrees, as the feeding assembly 24 continuously removes the material plate body 3 from the material plate loading box 12, the lifting module 21 needs to descend once after removing each material plate body 3, and the descent height is exactly equal to the height difference between two adjacent material plate bodies 3 in the material plate loading box 12. After all the material plate bodies 3 in the material plate loading box 12 have been removed, the flipping assembly 22 needs to flip back 90 degrees to switch the feeding assembly 23 from a vertical state back to a horizontal state. Then, the lifting module 21 drives the flipping assembly 22 and the feeding assembly 23 to transfer the material plate loading box 12 above the feeding assembly 23 to another material box conveying assembly 11 that is conveying back, thus completing the recycling of the material plate loading box 12.

[0037] In this embodiment, various sensors are also included for monitoring the operating status of the lifting and flipping assembly 22, such as an encoder for monitoring the flipping angle of the flipping assembly 22, a displacement sensor for monitoring the lifting data of the lifting module 21, and other sensors. The methods for monitoring the flipping data of the flipping assembly 22 and the lifting data of the lifting module 21 are existing conventional methods, which will not be described in detail here.

[0038] like Figure 6 and Figure 7 As shown, in this embodiment, the feeding assembly 23 includes a feeding conveyor frame 231 fixedly connected to the flip shaft 222, a feeding conveyor belt 233 disposed in the feeding conveyor frame 231, and a feeding drive motor 232 fixed to the feeding conveyor frame 231 and used to drive the feeding conveyor belt 233. The feeding assembly 23 also includes a locking cylinder 234 fixed on the feeding conveyor frame 231 and a locking rod 235 provided on the output shaft of the locking cylinder 234; The locking rod 235 is vertically fixed to the output shaft of the locking cylinder 234; When the lifting and tilting assembly 22 is in the non-tilting state, the locking rod 235 is set horizontally and perpendicularly to the feeding conveyor belt 233; The locking cylinder 234 is a rotary lifting cylinder.

[0039] In this embodiment, the feeding assembly 23 includes two parallel feeding conveyor belts 233. The feeding drive motor 232 can drive the two feeding conveyor belts 233 to run simultaneously. Both feeding conveyor belts 233 are located inside the feeding conveyor frame 231. In this embodiment, the locking rod 235 and the locking cylinder 234 are located between the two feeding conveyor belts 233. By setting the locking rod 235 and the locking cylinder 234, the material plate loading box 12 transferred to the feeding assembly 23 can be locked and released, avoiding the problem of the material plate loading box 12 tipping over after it is rotated 90 degrees with the flipping assembly 22 and the feeding assembly 23. In this embodiment, the locking cylinder 234 is a rotary lifting cylinder. In some embodiments, other types of cylinders can also be used, which will not be described in detail here.

[0040] like Figure 6 and Figure 7 As shown, in this embodiment, the flipping assembly 22 further includes a flipping drive motor 221 and a flipping transmission structure 223; The flipping drive motor 221, the flipping transmission structure 223, and the flipping shaft 222 are all mounted on the lifting bracket 211. The flipping drive motor 221 drives the flipping shaft 222 to rotate around its central axis on the lifting bracket 211 through the flipping transmission structure 223. The flip drive motor 221 is a servo motor. Technicians can also choose a stepper motor or other types of drive motors as needed, which will not be elaborated here.

[0041] In this embodiment, the flip transmission structure 223 can use a transmission gear set or transmission belt, or other conventional transmission structures, which will not be described in detail here.

[0042] In this embodiment, a rectangular housing is also fitted and fixed on the flip shaft 222, so that the feeding conveyor 231 of the feeding assembly 23 can be installed on the rectangular housing of the flip shaft 222.

[0043] like Figure 8 As shown, in this embodiment, the feeding assembly 24 includes a horizontally arranged feeding conveyor belt 241; With the lifting and tilting assembly 22 in the tilted state, the feeding end of the feeding conveyor belt 241 is located directly below the tilted material loading box 12; The feeding assembly 24 also includes a transverse sliding module 242 and two sets of positioning rollers 243 disposed on the output end of the transverse sliding module 242. The two sets of positioning rollers 243 are respectively located on both sides of the feeding conveyor belt 241. The sliding direction of the output end of the transverse sliding module 242 is perpendicular to the conveying direction of the feeding conveyor belt 241.

[0044] In this embodiment, the unloading component 24 is also provided with a transverse sliding module 242 and two sets of positioning rollers 243, so that after the material plate body 3 is transferred from the material plate loading box 12 to the unloading conveyor belt 241 of the unloading component 24, the material plate body 3 on the unloading conveyor belt 241 can be calibrated and positioned, which facilitates the subsequent gripping by the three-axis material picking component 25. The specific structure or construction of the unloading conveyor belt 241, positioning rollers 243 and transverse sliding module 242 in this embodiment are existing structures and will not be described in detail here.

[0045] like Figure 9 As shown, in this embodiment, the three-axis material handling assembly 25 includes a longitudinal linear module 251, a transverse linear module 252, a vertical linear module 253, and a material handling suction cup 254. Two sets of longitudinal linear modules 251 are provided. Both sets of longitudinal linear modules 251 are horizontally arranged and parallel to the discharge direction of the discharge component 26. The unloading component 24 and the discharge component 26 are located between the two sets of longitudinal linear modules 251. The front and rear ends of the longitudinal linear modules 251 along the discharge direction extend into the middle of the unloading component 24 and the discharge component 26, respectively. The two ends of the transverse linear module 252 are respectively set on the output ends of the two sets of longitudinal linear modules 251. The transverse linear module 252 is set horizontally and perpendicular to the discharge direction of the discharge component 26. The number of vertical linear modules 253 is equal to the number of discharge components 26, and the vertical linear modules 253 are all set on the conveying end of the horizontal linear modules 252. The material-picking suction cup 254 is disposed on the output end of the vertical linear module 253, and the material-picking station of the material-picking suction cup 254 is located directly below the vertical linear module 253.

[0046] In this embodiment, the longitudinal linear module 251, the transverse linear module 252, and the vertical linear module 253 are perpendicular to each other, allowing the material-picking suction cup 254 of the three-axis material-picking assembly 25 to move freely within its movable three-dimensional space. The structures of the longitudinal linear module 251, the transverse linear module 252, the vertical linear module 253, and the material-picking suction cup 254 are all existing structures and will not be described in detail here. In this embodiment, the number of material-picking suction cups 254 is the same as the number of unloading assemblies 24, so that the material-picking suction cups 254 can be bound together with the unloading assembly 24 when picking up materials, which is convenient for operation and maintenance.

[0047] like Figure 10 As shown, in this embodiment, the discharge assembly 26 includes a discharge conveyor frame 261 and a discharge rotating shaft 262 disposed on the discharge conveyor frame 261, as well as a plurality of rubber-coated rollers 263 mounted and fixed on the discharge rotating shaft 262. The discharge assembly 26 also includes a diagonal brace 264; The discharge module includes a discharge frame, the infeed end of the discharge conveyor 261 is fixed on the discharge frame, and the discharge end of the discharge conveyor 261 is suspended, so that the rubber-coated roller 263 of the discharge component 26 can transport the material plate body 3 to the next process, i.e. the post-processing line. One end of the diagonal brace 264 is fixed to the discharge frame, and the other end is fixed to the discharge conveyor frame 261. By setting the diagonal brace 264, the structural stability of the module can be improved.

[0048] In this embodiment, gears or sprockets are also provided at both ends of the discharge shaft 262. The transmission structure is set on the discharge conveyor frame 261 and also includes a drive motor that drives all the discharge shafts 262 to rotate synchronously. The drive motor, the discharge shaft 262 and the transmission structure are all existing conventional structures and will not be described in detail here.

[0049] In this embodiment, the rubber-coated roller 263 has a certain degree of elasticity, which prevents the rubber-coated roller 263 from being damaged during transportation. In addition, the rubber-coated roller 263 is also provided with several weight-reducing holes, which can save materials on the one hand and improve its flexibility on the other.

In this embodiment, each set of waste board storage boxes 271 includes two storage cavities, and the two sets of waste board storage assemblies 27 have a total of four storage cavities. The four storage cavities can correspond to the number of structures such as the unloading assembly 24 and the material retrieval suction cup 254, which facilitates the classification of waste board collection from each line in this embodiment and facilitates subsequent statistics and debugging.

[0051] In this embodiment, the discharge module also includes a visual recognition component disposed directly above the discharge component 26. The visual recognition component in this embodiment is an inverted camera fixed to the discharge frame. It can identify the main body 3 of the material plate with defects such as gaps. How to identify the main body 3 of the material plate with defects can be achieved by using conventional solutions in the industry such as image comparison, which will not be elaborated here.

[0053] In this embodiment, the material box conveying assembly 11 is provided with eight sets, with four sets on each of the upper and lower layers corresponding to four sets of lifting and flipping assemblies 22 and four sets of unloading assemblies 24 respectively.
