Description

Technical Field

[0001] This invention relates to the field of low-temperature co-fired ceramic production technology, specifically a high-precision cutting and pre-lamination machine. Background Technology

[0002] LTCC, or Low Temperature Co-fired Ceramic, is a technology that uses low-temperature fired ceramic powder to make a slurry, which is then printed or cast onto a green ceramic tape. The resulting slurry is then processed through circuit printing, lamination, cutting, sintering, and other techniques to create a three-dimensional circuit board.

[0003] Layer stacking involves piling multiple layers of green ceramic tape together and interconnecting them using processes such as vias and metallization. The more layers an LTCC substrate has, the higher the circuit integration, but the higher the cost. This places higher demands on the layer stacking process, requiring optimization of the stacking sequence and interconnection techniques to reduce substrate stress and deformation, and improve substrate reliability and conductivity.

[0004] During the LTCC stacking process, it is essential to ensure the alignment accuracy between each layer. Alignment accuracy includes the consistency of layer thickness and the accuracy of the stacking position. Poor alignment can lead to degraded circuit performance or open circuits. Insufficient bonding between ceramic layers can result in porosity, inclusions, and cracks due to incomplete gas removal from the metallization layer during high-temperature firing.

[0005] Existing common lamination equipment uses a vision system to align and laminate green ceramic tiles. The lamination accuracy is affected by the accuracy of the vision and the accuracy of mechanical correction, often resulting in defects caused by lamination misalignment. Furthermore, it is a manual operation, prone to contamination, and has low efficiency.

[0006] Based on this, a high-precision cutting and pre-lamination machine is now available, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] In one embodiment, such as Figures 1-8 As shown, the high-precision cutting and pre-lamination machine includes a frame 1 and a control screen 3. The control screen 3 is provided on the upper surface of the frame 1. It also includes a transmission module 5, a transfer component 6, a positioning and lifting cutting component 7, and a pre-lamination component 8.

[0036] The positioning and lifting cutting assembly 7 includes a support plate 9 and a cutting blade 10. A first fixing plate 17 is fixedly connected to the upper surface of the frame 1. Two symmetrical second fixing plates 19 are fixedly connected to the upper surface of the first fixing plate 17. A first linear guide rail 13 is provided on the opposite sidewalls of the two second fixing plates 19. The support plate 9 is slidably mounted on the first linear guide rail 13. A first motor 16 is fixedly connected to the upper surface of the frame 1 via a bracket. A lifting plate 38 is fixedly connected to the lower surface of the support plate 9 via a connecting rod. The lower surface of the first fixing plate 17 is connected via a bearing. A ball screw 18 is connected to the first motor 16 and the lifting plate 38. Four cutting cylinders 15 are fixedly connected to the upper surface of the first fixed plate 17. Each cutting cylinder 15 has a cutting blade 10 fixedly connected to its output end. Several lifting rods 14 are provided between the cutting blade 10 and the first fixed plate 17. A positioning cylinder 11 is provided on the side wall of one of the support plates 9. A positioning pin 12 is fixedly connected to the upper surface of another support plate 9. Several third electromagnets 40 are provided on the upper surface of the support plate 9.

[0037] The transfer assembly 6 is located above the frame 1 and is used to move the green ceramic sheet on the positioning and lifting cutting assembly 7 to the pre-stack assembly 8;

[0038] The pre-lamination assembly 8 is disposed on the upper surface of the frame 1 and is used to laminate green ceramic sheets.

[0039] When the first green ceramic tile (with iron frame) flows from the input module 4 into the positioning and lifting cutting assembly 7, the green ceramic tile is stopped on the input module 4. The first motor 16 drives the ball screw 18 to rotate, the support plate 9 rises, and lifts the green ceramic tile from the input module 4. The positioning cylinder 11 moves out and positions the green ceramic tile iron frame on the front positioning pin 12. The third electromagnet 40 is energized to attract the iron frame flat. Then the support plate 9 rises again and lifts the green ceramic tile (with iron frame) onto the transfer assembly 6. The transfer platform has a second electromagnet 30 and a ceramic transfer porous plate 29, which attract the iron frame and the green ceramic tile, and then moves it to the pre-stack assembly 8.

[0040] In one embodiment, such as Figure 1 and Figure 3 As shown, the upper surface of the frame 1 is provided with an input module 4, which is located between the transfer component 6 and the positioning, lifting and cutting component 7.

[0041] The input module 4 facilitates the batch transportation of raw ceramic tiles to the positioning, lifting, and cutting component 7.

[0042] In one embodiment, such as Figure 1 and Figure 3 As shown, a transfer module 5 is provided on the upper surface of the frame 1, and the transfer module 5 is located between the transfer assembly 6 and the pre-stacked assembly 8.

[0043] The output module 5 facilitates the bulk transportation of pre-stacked green ceramic tiles.

[0044] In one embodiment, such as Figure 8 As shown, the pre-stacked assembly 8 includes a lifting cylinder 23 and a connecting plate 37. Two symmetrical connecting plates 37 are fixedly connected to the upper surface of the frame 1. Two symmetrical guide rods 24 are fixedly connected to the upper surface of the connecting plate 37. The four guide rods 24 are slidably connected through a sliding plate 39. Four symmetrical fixed cylinders 22 are fixedly connected to the upper surface of the sliding plate 39. The guide rods 24 are slidably connected to the fixed cylinders 22. The top ends of the four fixed cylinders 22 are fixedly connected to a perforated pre-stacked plate 21.

[0045] When the ceramic transfer porous plate 29 adsorbs the first green ceramic sheet (with iron frame) and transfers it above the pre-stacked assembly 8, the lifting cylinder 23 extends, the porous pre-stacked plate 21 rises and contacts the green ceramic sheet (with iron frame), the ceramic transfer porous plate 29 breaks the vacuum, the second electromagnet 30 opens, and at the same time the porous pre-stacked plate 21 adsorbs the green ceramic sheet. The electromagnet 20 is energized, and the lifting cylinder 23 is driven to descend, adsorbing the first green ceramic sheet (with iron frame) and waiting for the second green ceramic sheet.

[0046] When the ceramic transfer porous plate 29 adsorbs the second green ceramic sheet (without iron frame) and transfers it above the porous pre-stacked plate 21, the lifting cylinder 23 rises, stacking the first green ceramic sheet (with iron frame) with the second green ceramic sheet (without iron frame) together. At this time, the ceramic transfer porous plate 29 breaks the vacuum, and the lifting cylinder 23 descends to wait for the third sheet. The subsequent actions of the third, fourth, and so on are the same as the second sheet. After all the pre-stacked layers are completed, the pre-stacked assembly 8 breaks the vacuum, the electromagnet 20 opens, and the lifting cylinder 23 is driven to descend, dropping the pre-stacked green ceramic sheet (with iron frame at the bottom) onto the output module 5, from which it flows out to the subsequent workstation.

[0047] In one embodiment, such as Figure 1 and Figure 4 As shown, a first buffer 25 is provided on the upper surface of the connecting plate 37.

[0048] The first buffer 25 reduces the impact of the sliding plate 39.

[0049] In one embodiment, such as Figure 4 and Figure 5As shown, the transfer assembly 6 includes columns 26 and a transfer platform 27. Several columns 26 are fixedly connected to the upper surface of the frame 1. The top of the columns 26 are fixedly connected to the transfer platform 27. Two symmetrical second linear guide rails 31 are fixedly connected to the upper surface of the transfer platform 27. The two second linear guide rails 31 are slidably connected to a moving plate 36. A ceramic transfer perforated plate 29 is fixedly connected to the lower surface of the moving plate 36. A second motor 34 is fixedly connected to the lower surface of the transfer platform 27 through a bracket. A first synchronous pulley 32 and a second synchronous pulley 33 are connected to the lower surface of the transfer platform 27 through bearings. The first synchronous pulley 32 and the second synchronous pulley 33 cooperate with a belt 35. One side of the belt 35 is fixedly connected to the moving plate 36. The second synchronous pulley 33 is connected to the second motor 34. A positioning screw 41 is provided on the lower surface of the transfer platform 27.

[0050] When the movable plate 36 moves, the second motor 34 is in torque control mode. The left and right positions of the multi-hole platform are mechanically positioned by positioning screws 41. Compared with the servo position control mode of transmission, this mechanical positioning is very stable and reliable. The positioning accuracy can be controlled within 0.0015mm, which greatly improves the position accuracy of the pre-stacked layer and ensures the stability and reliability of the pre-stacked layer.

[0051] When the first green ceramic tile (with iron frame) rises from the support plate 9 onto the transfer assembly 6, the ceramic transfer porous plate 29 adsorbs the green ceramic tile, the second electromagnet 30 adsorbs the iron frame, the second motor 34 rotates, and the belt 35 drives the ceramic transfer porous plate 29 to move above the pre-stack assembly 8. The pre-stack assembly 8 rises and adsorbs the green ceramic tile (with iron frame) onto the porous pre-stack plate 21.

[0052] In one embodiment, such as Figure 5 , Figure 6 , Figure 8 As shown, a plurality of electromagnets 20 are provided on the upper surface of the porous pre-stacked plate 21, and a plurality of second electromagnets 30 corresponding to the electromagnets 20 are fixedly connected to the lower surface of the ceramic transfer porous plate 29.

[0053] Electromagnet 20: When the electromagnet is energized, it attracts the raw ceramic tile (with an iron frame).

[0054] In one embodiment, such as Figure 5 As shown, a second buffer 28 is provided on the lower surface of the transfer stage 27.

[0055] The second buffer 28 reduces the impact on the moving plate 36.

[0056] The above embodiments disclose a high-precision cutting and pre-lamination machine.

[0057] S1: When the first green ceramic tile (with iron frame) flows from the input module 4 into the positioning and lifting cutting component 7, the green ceramic tile is stopped on the input module 4. The first motor 16 drives the ball screw 18 to rotate, the support plate 9 rises, and lifts the green ceramic tile from the input module 4. The positioning cylinder 11 moves out and positions the green ceramic tile iron frame on the front positioning pin 12. The third electromagnet 40 is energized and attracts the iron frame flat. Then the support plate 9 rises again and lifts the green ceramic tile (with iron frame) onto the transfer component 6. The transfer platform has a second electromagnet 30 and a ceramic transfer porous plate 29, which attract the iron frame and the green ceramic tile, and then moves it to the pre-stacked component 8.

[0058] S2: When the second green ceramic tile is adsorbed onto the transfer component 6, the four sets of cutting cylinders 15 extend, driving the four cutting blades 10 to rise to the transfer component 6 to cut the second green ceramic tile. After that, the cutting blades 10 retract, at which point the iron frame and the green ceramic tile have separated. The iron frame falls onto the support plate 9, and the support plate 9 descends, placing the iron frame onto the inflow module 4. The iron frame flows out from the rear of the inflow module 4 for stacking.

[0059] S3: When the green ceramic tile (with iron frame) is positioned on the support plate 9 and continues to rise to the transfer assembly 6, the first motor 16 uses torque control to ensure that the iron frame and the transfer platform are in complete contact during the handover, thus ensuring the position during the handover.

[0060] S4: When the first green ceramic tile (with iron frame) rises from the support plate 9 onto the transfer assembly 6, the ceramic transfer porous plate 29 adsorbs the green ceramic tile, the second electromagnet 30 adsorbs the iron frame, the second motor 34 rotates, and the belt 35 drives the ceramic transfer porous plate 29 to move above the pre-stack assembly 8. The pre-stack assembly 8 rises and adsorbs the green ceramic tile (with iron frame) onto the porous pre-stack plate 21.

[0061] S5: When the moving plate 36 moves, the second motor 34 is in torque control mode. The left and right positions of the multi-hole platform are mechanically positioned by positioning screws 41. Compared with the servo position control mode of transmission, this mechanical positioning is very stable and reliable. The positioning accuracy can be controlled within 0.0015mm, which greatly improves the position accuracy of the pre-stacked layer and ensures the stability and reliability of the pre-stacked layer.

[0062] S6: When the ceramic transfer porous plate 29 adsorbs the first green ceramic sheet (with iron frame) and transfers it above the pre-stacked assembly 8, the lifting cylinder 23 extends, the porous pre-stacked plate 21 rises and contacts the green ceramic sheet (with iron frame), the ceramic transfer porous plate 29 breaks the vacuum, the second electromagnet 30 opens, and at the same time the porous pre-stacked plate 21 adsorbs the green ceramic sheet. The electromagnet 20 is energized, and the lifting cylinder 23 is driven to descend, adsorbing the first green ceramic sheet (with iron frame) and waiting for the second green ceramic sheet.

[0063] S7: When the ceramic transfer porous plate 29 adsorbs the second green ceramic sheet (without iron frame) and transfers it above the porous pre-stacked plate 21, the lifting cylinder 23 rises, stacking the first green ceramic sheet (with iron frame) with the second green ceramic sheet (without iron frame) together. At this time, the ceramic transfer porous plate 29 breaks the vacuum, and the lifting cylinder 23 descends to wait for the third sheet. The subsequent actions of the third, fourth, and so on are the same as the second sheet. After all the pre-stacked layers are completed, the pre-stacked assembly 8 breaks the vacuum, the electromagnet 20 opens, and the lifting cylinder 23 is driven to descend, dropping the pre-stacked green ceramic sheet (with iron frame at the bottom) onto the output module 5, from which it flows out to the subsequent workstation.

[0064] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
