Description

Technical Field

[0001] The present invention relates to the technical field of film tearing equipment, and specifically to an automatic film tearing equipment for copper-clad ceramic substrates. Background Art

[0002] A copper-clad ceramic carrier is a power semiconductor device with a layer of copper foil wrapped on the surface of a ceramic substrate, having excellent thermal conductivity, excellent insulation performance, and high strength, and is suitable for use in power devices, especially for applications in high-power, high-frequency, and high-temperature environments. The manufacturing of copper-clad ceramic carriers has the following steps: copper-ceramic sintering, pattern transfer, laser cutting, etc.

[0003] During the pattern transfer process, a photosensitive film needs to be pasted on the copper-clad ceramic carrier, and then the pattern of the film is transferred to the photosensitive layer of the carrier through exposure, and then the film on the carrier is removed. The size of the copper-clad ceramic carrier is small, and the frequent film pasting and removing processes have high requirements for the accuracy and efficiency of manual operation, and the ceramic is brittle, so there is a risk of breakage in manual operation.

[0004] Since the thickness of the photosensitive film pasted on different pattern transfer copper-clad ceramic carriers will be adjusted according to the pattern, but the film tearing mechanism of general automatic film tearing equipment cannot automatically adjust the clamping force according to the thickness of the film. When facing a relatively thin film, due to the relatively large clamping force, it may cause scratches and damage to the surface of the substrate when the film is separated from the substrate, thereby damaging the film or the surface of the substrate. For a relatively thick film, it may also cause problems such as the film not being torn off smoothly due to insufficient clamping force, resulting in film residue, etc., affecting the product quality. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic film tearing equipment for copper-clad ceramic substrates to solve the problems raised in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] An automatic film tearing equipment for copper-clad ceramic substrates, the film tearing equipment includes a frame, a stack cart, a robotic arm, a conveying mechanism, a limiting mechanism, a centering mechanism, an angle adjusting mechanism, a film tearing mechanism, and a temporary storage mechanism. The frame and the stack cart are fixedly connected, the robotic arm and the frame are fixedly connected, the conveying mechanism and the frame are fixedly connected, the limiting mechanism and the frame are fixedly connected, the centering mechanism is slidably connected to the conveying mechanism, the angle adjusting mechanism and the frame are fixedly connected, the film tearing mechanism and the frame are fixedly connected, and the temporary storage mechanism and the conveying mechanism are fixedly connected.

[0008] Based on the frame, the frame is fixedly connected to the laminated cart. During operation, the robotic arm grabs the copper-clad ceramic substrate from the laminated cart and places it on the conveying mechanism fixedly connected to the frame. The conveying mechanism starts to work and conveys the substrate in the processing direction. When the substrate reaches the limiting mechanism, the limiting mechanism blocks the substrate, causing the substrate to pause moving and the conveying mechanism to stop working. At the same time, the centering mechanism slidably connected to the conveying mechanism starts to work and performs centering adjustment on the substrate. After centering is completed, the angle adjustment mechanism fixedly connected to the frame adjusts the angle of the substrate. After the adjustment is completed, the limiting mechanism moves away, and the conveying mechanism continues to convey the substrate. The film tearing mechanism fixedly connected to the frame performs film tearing treatment on the copper-clad ceramic substrate. The substrate after film tearing is conveyed by the conveying mechanism to the temporary storage mechanism fixedly connected to it for temporary storage. The device realizes the automatic film tearing treatment of the copper-clad ceramic substrate through the close cooperation of each mechanism in sequence along the processing direction.

[0009] Furthermore, the film tearing mechanism includes a first lead screw module, a film sticking component, a clamping component, and a film collecting frame. The first lead screw module is fixedly connected to the frame. The moving end of the first lead screw module is fixedly connected to the film sticking component. The moving end of the first lead screw module is fixedly connected to the clamping component. The film collecting frame is fixedly connected to the frame.

[0010] By driving the first lead screw module fixedly connected to the frame, the first lead screw module is driven, so that the film sticking component and the clamping component fixedly connected to the moving end of the first lead screw module move above the copper-clad ceramic substrate. The film sticking component picks up the adhesive film on the copper-clad ceramic substrate, and the clamping component clamps the picked-up adhesive film. The conveying mechanism conveys the copper-clad ceramic substrate, so that the adhesive film gradually detaches from the copper-clad ceramic substrate. By driving the first lead screw module again, the film sticking component and the clamping component move to the film collecting frame, and the clamping component releases the adhesive film, so that the torn-off adhesive film is placed into the film collecting frame.

[0011] Furthermore, the film sticking component includes an electric cylinder, a first mounting frame, a film feeding reel, a tape, a rotating shaft, a film winding reel, and a first motor. The output end of the electric cylinder is fixedly connected to the first mounting frame. The film feeding reel is rotatably connected to the first mounting frame. The tape is fixedly connected to the film feeding reel. The rotating shaft is rotatably connected to the first mounting frame. The film winding reel is rotatably connected to the first mounting frame. There are two first motors, and the output ends of the two first motors are respectively fastened to the film feeding reel and the film winding reel.

[0012] By respectively fastening the output ends of the first motors to the film feeding reel and the film winding reel, the first motors are driven to drive the film feeding reel and the film winding reel to rotate, so that a new section of tape moves to the rotating shaft. By fixedly connecting the output end of the electric cylinder to the first mounting frame and driving the electric cylinder, the first mounting frame descends, so that the tape comes into contact with the adhesive film on the copper-clad ceramic substrate. By driving the electric cylinder to raise the first mounting frame, the tape picks up the adhesive film, thus completing the operation of pasting the adhesive film.

[0013] Further, the clamping assembly includes a first mounting plate, a fixed block, a bidirectional lead screw, a second motor, a first clamping plate, a second clamping plate and an adjusting unit. The first mounting plate is fixedly connected to the fixed block. The bidirectional lead screw is rotatably connected to the fixed block. The second motor is fixedly connected to the first mounting plate. The output end of the second motor is fixedly connected to the bidirectional lead screw. The first clamping plate is threadedly connected to the bidirectional lead screw. The second clamping plate is slidably connected to the bidirectional lead screw. The adjusting unit is threadedly connected to the bidirectional lead screw.

[0014] Through the fixed connection between the first mounting plate and the fixed block, the fixed connection between the second motor and the first mounting plate, and the rotational connection of both ends of the bidirectional lead screw to the fixed block and the fixed connection of the output end of the second motor respectively, both ends of the bidirectional lead screw are fixed, and at the same time, the second motor can drive the bidirectional lead screw to rotate along its own axis. When it is necessary to clamp the adhesive film on the copper-clad ceramic substrate, the second motor drives the bidirectional lead screw to rotate. Through the threaded connection between the first clamping plate and the bidirectional lead screw, and the threaded connection between the adjusting unit and the bidirectional lead screw, the first clamping plate moves towards the second clamping plate, and the adjusting unit pushes the second clamping plate towards the first clamping plate, so as to clamp the adhesive film on the copper-clad ceramic substrate by the first clamping plate and the second clamping plate.

[0015] Further, the adjusting unit includes a connecting slide plate, a wedge block, a first connecting block, a slide rod and a spring. The connecting slide plate is threadedly connected to the bidirectional lead screw. The wedge block is slidably connected to the connecting slide plate. The first connecting block is fixedly connected to the connecting slide plate. The slide rod is fixedly connected to the first connecting block. The wedge block is provided with a sliding groove. The slide rod is slidably connected to the sliding groove. The spring is sleeved outside the slide rod. The wedge block abuts against the second clamping plate.

[0016] Through the threaded connection between the connecting slide plate and the bidirectional lead screw, the connecting slide plate moves as the bidirectional lead screw rotates. The wedge block abuts against the second clamping plate, so that the connecting slide plate drives the wedge block to push the second clamping plate towards the first clamping plate. When the second clamping plate and the first clamping plate clamp the adhesive film, the inclined surface of the wedge block continues to slide towards the inclined surface of the second clamping plate. While the wedge block moves towards the second clamping plate, it also moves upward. The slide rod slides towards the sliding groove, and the spring is compressed, generating an elastic force on the wedge block, so that the wedge block presses the second clamping plate tightly, and further clamps the second clamping plate and the first clamping plate. When the adhesive film is thicker, the distance between the second clamping plate and the first clamping plate is larger. The longer the distance that the wedge block moves towards the second clamping plate, the greater the elastic force of the spring on the wedge block, and vice versa, enabling it to adjust the clamping force according to the thickness of the adhesive film.

[0017] Further, the conveying mechanism includes a third motor, a first bracket, rollers and a transmission chain. There are several rollers. The several rollers are rotatably connected to the first bracket. The output end of the third motor is fixedly connected to one roller. The third motor is fixedly connected to the frame. The transmission chain is sleeved outside the several rollers.

[0018] By arranging a plurality of rods that can rotate on the first support, fixedly connecting the output end of the third motor to one rod, driving the connected rod to rotate by the third motor, driving the transmission chain sleeved on it to rotate by the rotation of the rod, and driving all the rods to rotate, so as to be able to convey copper-clad ceramic substrates.

[0019] Furthermore, the limiting mechanism includes a first limiting plate and a lifting cylinder. The lifting cylinder is fixedly connected to the frame, and the output end of the lifting cylinder is fixedly connected to the first limiting plate.

[0020] By fixedly connecting the output end of the lifting cylinder to the first limiting plate, with the first limiting plate located between the rods, driving the first limiting plate to rise by the lifting cylinder, so that the first limiting plate blocks the conveyed copper-clad ceramic substrate, thereby making the copper-clad ceramic substrate stop at the designated position.

[0021] Furthermore, the centering mechanism includes a double-acting cylinder, a first connecting rod, and eight second limiting plates. The double-acting cylinder is fixedly connected to the frame. There are two first connecting rods. The two output ends of the double-acting cylinder are respectively fixedly connected to the two first connecting rods. There are eight second limiting plates. The eight second limiting plates are respectively fixedly connected to the two first connecting rods, and the eight second limiting plates are slidably connected to the rods.

[0022] By the double-acting cylinder installed on the frame, with the two output ends of the double-acting cylinder respectively fixedly connected to the two first connecting rods, driving the two first connecting rods to approach the double-acting cylinder simultaneously by the double-acting cylinder, and with the eight second limiting plates slidably connected to the rods, making the eight second limiting plates on the first connecting rod approach each other in pairs, so as to perform centering adjustment on four copper-clad ceramic substrates simultaneously.

[0023] Furthermore, the angle adjustment mechanism includes a second lead screw module, a second mounting plate, a slider, a guide rail, a fixing plate, a rotary cylinder, a second connecting block, and a suction cup. The second lead screw module is fixedly connected to the frame. The moving end of the second lead screw module is fixedly connected to the second mounting plate. The slider is fixedly connected to the second mounting plate. The guide rail is slidably connected to the slider. The guide rail is fixedly connected to the fixing plate. The rotary cylinder is fixedly connected to the second mounting plate. The output end of the rotary cylinder is fixedly connected to the second connecting block. The suction cup is fixedly connected to the second connecting block.

[0024] The mobile end of the second lead screw module is fixedly connected to one end of the second mounting plate. The other end of the second mounting plate is fixedly connected to the slider. The slider is slidably connected to the guide rail, and the guide rail is mounted on the fixing plate parallel to the second lead screw module, enabling the second lead screw module to drive the second mounting plate to descend linearly. The descent of the second mounting plate drives the second connecting block to descend, causing the suction cup on the second connecting block to contact the copper-clad ceramic substrate. By means of an air pump, negative pressure is generated in the suction cup, thereby sucking the copper-clad ceramic substrate tightly. The output end of the rotary cylinder is fixedly connected to the second connecting block, enabling the rotary cylinder to drive the second connecting block to rotate. The rotation of the second connecting block drives the copper-clad ceramic substrate to rotate, thus completing the angle adjustment of the copper-clad ceramic substrate.

[0025] Furthermore, the temporary storage mechanism includes a second mounting frame, a transmission shaft, a gear, a fourth motor, a rack, a second bracket, and a second connecting rod. The second mounting frame is fixedly connected to the first bracket. The transmission shaft is rotatably connected to the second mounting frame. The gear is keyed to the transmission shaft. The fourth motor is fixedly connected to the second mounting frame. The output end of the fourth motor is fixedly connected to the transmission shaft. The rack meshes with the gear. The rack is fixedly connected to the second bracket. The second connecting rod is fixedly connected to the second bracket.

[0026] By fixedly connecting the output end of the fourth motor on the second mounting frame to the transmission shaft, the fourth motor drives the transmission shaft to rotate. The transmission shaft and the gear are connected by a keyway, enabling the transmission shaft to drive the gear to rotate. Due to the meshing of the rack and the gear, the rack moves upward. Since the second bracket is fixedly connected to the rack, the second bracket moves upward together with the rack. By means of the provided second connecting rod, the copper-clad ceramic substrate is placed on the second connecting rod. Since the second connecting rod is fixedly connected to the second bracket, the second connecting rod rises, and the copper-clad ceramic substrate rises with the second connecting rod, thereby enabling the copper-clad ceramic substrate to leave the conveying mechanism, thus completing the temporary storage of the copper-clad ceramic substrate.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. By the threaded connection between the connecting slide plate and the bidirectional lead screw, the connecting slide plate moves as the bidirectional lead screw rotates. The connecting slide plate drives the wedge block to push the second clamping plate towards the first clamping plate. When both the second clamping plate and the first clamping plate contact the adhesive film, the inclined surface of the wedge block continues to slide on the inclined surface of the second clamping plate. While the wedge block moves towards the second clamping plate, it also moves upward. The sliding rod slides towards the sliding groove, and the spring is compressed, generating an elastic force on the wedge block to press the second clamping plate tightly, thereby clamping the second clamping plate and the first clamping plate. When the adhesive film is thick, the distance between the second clamping plate and the first clamping plate is large. The longer the distance the wedge block moves towards the second clamping plate, the greater the elastic force of the spring on the wedge block, and vice versa. This enables the clamping force to be adjusted according to the thickness of the adhesive film, ensuring effective clamping of the adhesive film for smooth film tearing, while preventing damage to the adhesive film or the substrate due to improper force, thereby ensuring product quality.

[0029] 2. The copper-clad ceramic substrate is automatically grasped by a robotic arm and conveyed by a conveying mechanism. At the same time, an adjusting mechanism is provided thereon to automatically adjust the position of the copper-clad ceramic substrate during conveying. Then, the copper-clad ceramic substrate is automatically peeled off the film by a film-peeling mechanism, realizing automated operation, saving labor costs, and at the same time making the film-peeling action fixed, reducing the possibility of ceramic cracks generated during manual operation.

Detailed implementation mode

[0044] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Embodiment: As Figures 1-3 shown, the present invention provides a technical solution for an automatic film tearing device for copper-clad ceramic substrates. An automatic film tearing device for copper-clad ceramic substrates includes a frame 1, a lamination cart 2, a robotic arm 3, a conveying mechanism 4, a limiting mechanism 5, a centering mechanism 6, an angle adjusting mechanism 7, a film tearing mechanism 8, and a temporary storage mechanism 9. The frame 1 and the lamination cart 2 are fixedly connected, the robotic arm 3 and the frame 1 are fixedly connected, the conveying mechanism 4 and the frame 1 are fixedly connected, the limiting mechanism 5 and the frame 1 are fixedly connected, the centering mechanism 6 and the conveying mechanism 4 are slidably connected, the angle adjusting mechanism 7 and the frame 1 are fixedly connected, the film tearing mechanism 8 and the frame 1 are fixedly connected, and the temporary storage mechanism 9 and the conveying mechanism 4 are fixedly connected.

[0046] Based on the frame 1, the frame 1 is fixedly connected to the lamination cart 2. During operation, the robotic arm 3 grabs the copper-clad ceramic substrate from the lamination cart 2 and places it on the conveying mechanism 4 fixedly connected to the frame 1. The conveying mechanism 4 starts to work and conveys the substrate in the processing direction. When the substrate reaches the limiting mechanism 5, the limiting mechanism 5 blocks the substrate, causing the substrate to pause moving, and the conveying mechanism 4 also stops working. At the same time, the centering mechanism 6 slidably connected to the conveying mechanism 4 starts to work and performs centering adjustment on the substrate. After centering is completed, the angle adjustment mechanism 7 fixedly connected to the frame 1 adjusts the angle of the substrate. After the adjustment is completed, the limiting mechanism 5 moves away, and the conveying mechanism 4 continues to convey the substrate. The film tearing mechanism 8 fixedly connected to the frame 1 performs film tearing treatment on the copper-clad ceramic substrate. The substrate after film tearing is conveyed by the conveying mechanism 4 to the temporary storage mechanism 9 fixedly connected thereto for temporary storage. The device realizes the automatic film tearing treatment of the copper-clad ceramic substrate through the close cooperation of each mechanism along the conveying direction.

[0047] As Figure 1 、 Figure 2 and Figure 4 shown, the film tearing mechanism 8 includes a first lead screw module 81, a film sticking component 82, a clamping component 83, and a film collecting frame 84. The first lead screw module 81 is fixedly connected to the frame 1. The moving end of the first lead screw module 81 is fixedly connected to the film sticking component 82. The moving end of the first lead screw module 81 is fixedly connected to the clamping component 83. The film collecting frame 84 is fixedly connected to the frame 1.

[0048] Through the first lead screw module 81 fixedly connected to the frame 1, the first lead screw module 81 is driven, so that the film sticking component 82 and the clamping component 83 fixedly connected to the moving end of the first lead screw module 81 move above the copper-clad ceramic substrate. The film sticking component 82 sticks up the adhesive film on the copper-clad ceramic substrate, and the clamping component 83 clamps the lifted adhesive film. The conveying mechanism 4 conveys the copper-clad ceramic substrate, causing the adhesive film to gradually separate from the copper-clad ceramic substrate. By driving the first lead screw module 81 again, the film sticking component 82 and the clamping component 83 move to the film collecting frame 84, and the clamping component 83 releases the adhesive film, so that the torn adhesive film is placed into the film collecting frame 84.

[0049] As Figure 5 and Figure 6 shown, the film sticking component 82 includes an electric cylinder 821, a first mounting frame 822, a film releasing roller 823, a tape 824, a rotating shaft 825, a film collecting roller 826, and a first motor 827. The output end of the electric cylinder 821 is fixedly connected to the first mounting frame 822. The film releasing roller 823 is rotatably connected to the first mounting frame 822. The tape 824 is fixedly connected to the film releasing roller 823. The rotating shaft 825 is rotatably connected to the first mounting frame 822. The film collecting roller 826 is rotatably connected to the first mounting frame 822. There are two first motors 827, and the output ends of the two first motors 827 are respectively fixedly connected to the film releasing roller 823 and the film collecting roller 826.

[0050] The output ends of two No. 1 motors 827 are respectively fixedly connected to the unwinding shaft 823 and the rewinding shaft 826, so that the No. 1 motor 827 drives the unwinding shaft 823 and the rewinding shaft 826 to rotate, and a new section of tape 824 is moved onto the rotating shaft 825. The output end of the electric cylinder 821 is fixedly connected to the first mounting bracket 822, and the electric cylinder 821 is driven to lower the first mounting bracket 822, so that the tape 824 contacts the adhesive film on the copper-clad ceramic substrate. Then, the electric cylinder 821 drives the first mounting bracket 822 to rise, and the tape 824 picks up the adhesive film, thus completing the pasting operation of the adhesive film.

[0051] As Figure 7 shown, the clamping assembly 83 includes a first mounting plate 831, a fixed block 832, a bidirectional lead screw 833, a No. 2 motor 834, a first clamping plate 835, a second clamping plate 836 and an adjusting unit 837. The first mounting plate 831 is fixedly connected to the fixed block 832, the bidirectional lead screw 833 is rotatably connected to the fixed block 832, the No. 2 motor 834 is fixedly connected to the first mounting plate 831, the output end of the No. 2 motor 834 is fixedly connected to the bidirectional lead screw 833, the first clamping plate 835 is threadedly connected to the bidirectional lead screw 833, the second clamping plate 836 is slidably connected to the bidirectional lead screw 833, and the adjusting unit 837 is threadedly connected to the bidirectional lead screw 833.

[0052] By fixedly connecting the first mounting plate 831 to the fixed block 832, fixedly connecting the No. 2 motor 834 to the first mounting plate 831, and rotatably connecting the two ends of the bidirectional lead screw 833 to the fixed block 832 and fixedly connecting the output end of the No. 2 motor 834, the two ends of the bidirectional lead screw 833 are fixed, and at the same time, the No. 2 motor 834 can drive the bidirectional lead screw 833 to rotate along its own axis. When it is necessary to clamp the adhesive film on the copper-clad ceramic substrate, the No. 2 motor 834 drives the bidirectional lead screw 833 to rotate. Due to the threaded connection between the first clamping plate 835 and the bidirectional lead screw 833 and the threaded connection between the adjusting unit 837 and the bidirectional lead screw 833, the first clamping plate 835 moves towards the second clamping plate 836, and the adjusting unit 837 pushes the second clamping plate 836 towards the first clamping plate 835, thereby clamping the adhesive film on the copper-clad ceramic substrate by the first clamping plate 835 and the second clamping plate 836.

[0053] As Figure 7 and Figure 8As shown, the adjusting unit 837 includes a connecting slide plate 8371, a wedge 8372, a first connecting block 8373, a slide rod 8374 and a spring 8375. The connecting slide plate 8371 is threadedly connected to the bidirectional lead screw 833. The wedge 8372 is slidably connected to the connecting slide plate 8371. The first connecting block 8373 is fixedly connected to the connecting slide plate 8371. The slide rod 8374 is fixedly connected to the first connecting block 8373. The wedge 8372 is provided with a sliding groove 83721. The slide rod 8374 is slidably connected to the sliding groove 83721. The spring 8375 is sleeved outside the slide rod 8374. The wedge 8372 abuts against the second clamping plate 836.

[0054] Since the connecting slide plate 8371 is threadedly connected to the bidirectional lead screw 833, the connecting slide plate 8371 moves as the bidirectional lead screw 833 rotates. The wedge 8372 abuts against the second clamping plate 836, causing the connecting slide plate 8371 to drive the wedge 8372 to push the second clamping plate 836 towards the first clamping plate 835. When the second clamping plate 836 and the first clamping plate 835 clamp the adhesive film, the inclined surface of the wedge 8372 continues to slide towards the inclined surface of the second clamping plate 836. While the wedge 8372 moves towards the second clamping plate 836, it also moves upward. The slide rod 8374 slides into the sliding groove 83721, and the spring 8375 is compressed, generating an elastic force on the wedge 8372 to press the second clamping plate 836 tightly, thereby clamping the second clamping plate 836 and the first clamping plate 835 tightly. When the adhesive film is thicker, the distance between the second clamping plate 836 and the first clamping plate 835 is larger. The longer the distance the wedge 8372 moves towards the second clamping plate 836, the greater the elastic force of the spring 8375 on the wedge 8372, and vice versa, enabling it to adjust the clamping force according to the thickness of the adhesive film.

[0055] As Figure 1 、 Figure 2 and Figure 9 shown, the conveying mechanism 4 includes a third motor 41, a first bracket 42, rollers 43 and a transmission chain 44. There are several rollers 43, and the several rollers 43 are rotatably connected to the first bracket 42. The output end of the third motor 41 is fixedly connected to one of the rollers 43. The third motor 41 is fixedly connected to the frame 1. The transmission chain 44 is sleeved outside the several rollers 43.

[0056] By arranging several rollers 43 that can rotate on the first bracket 42, with the output end of the third motor 41 fixedly connected to one of the rollers 43, the third motor 41 drives the roller 43 connected to it to rotate. The rotation of the roller 43 drives the transmission chain 44 sleeved on it to rotate, and the transmission chain 44 drives all the rollers 43 to rotate, enabling it to convey the copper-clad ceramic substrate.

[0057] As Figure 10 and Figure 11As shown, the limit mechanism 5 includes a first limit plate 51 and a lifting cylinder 52. The lifting cylinder 52 is fixedly connected to the frame 1, and the output end of the lifting cylinder 52 is fixedly connected to the first limit plate 51.

[0058] Since the output end of the lifting cylinder 52 is fixedly connected to the first limit plate 51, and the first limit plate 51 is located between the rods 43, the lifting cylinder 52 drives the first limit plate 51 to rise, so that the first limit plate 51 blocks the conveyed copper-clad ceramic substrate, thereby stopping the copper-clad ceramic substrate at the specified position.

[0059] As Figure 10 and Figure 11 shown, the centering mechanism 6 includes a double-acting cylinder 61, a first connecting rod 62, and a second limit plate 63. The double-acting cylinder 61 is fixedly connected to the frame 1. There are two first connecting rods 62. The two output ends of the double-acting cylinder 61 are respectively fixedly connected to the two first connecting rods 62. There are eight second limit plates 63. The eight second limit plates 63 are respectively fixedly connected to the two first connecting rods 62, and the eight second limit plates 63 are slidably connected to the rods 43.

[0060] Through the double-acting cylinder 61 installed on the frame 1, the two output ends of the double-acting cylinder 61 are respectively fixedly connected to the two first connecting rods 62. The double-acting cylinder 61 drives the two first connecting rods 62 to approach the double-acting cylinder 61 at the same time. Through the sliding connection between the eight second limit plates 63 and the rods 43, the eight second limit plates 63 on the first connecting rod 62 approach each other in pairs, so as to perform centering adjustment on four copper-clad ceramic substrates at the same time.

[0061] As Figure 10 、 Figure 11 and Figure 12 shown, the angle adjustment mechanism 7 includes a second lead screw module 71, a second mounting plate 72, a slider 73, a guide rail 74, a fixing plate 75, a rotary cylinder 76, a second connecting block 77, and a suction cup 78. The second lead screw module 71 is fixedly connected to the frame 1. The moving end of the second lead screw module 71 is fixedly connected to the second mounting plate 72. The slider 73 is fixedly connected to the second mounting plate 72. The guide rail 74 is slidably connected to the slider 73. The guide rail 74 is fixedly connected to the fixing plate 75. The rotary cylinder 76 is fixedly connected to the second mounting plate 72. The output end of the rotary cylinder 76 is fixedly connected to the second connecting block 77. The suction cup 78 is fixedly connected to the second connecting block 77.

[0062] The mobile end of the second lead screw module 71 is fixedly connected to one end of the second mounting plate 72. The other end of the second mounting plate 72 is fixedly connected to the slider 73. The slider 73 is slidably connected to the guide rail 74, and the guide rail 74 is mounted on the fixed plate 75 parallel to the second lead screw module 71, enabling the second lead screw module 71 to drive the second mounting plate 72 to descend linearly. The descent of the second mounting plate 72 drives the second connecting block 77 to descend, causing the suction cup 78 on the second connecting block 77 to contact the copper-clad ceramic substrate. The air pump is used to generate negative pressure in the suction cup 78, thereby tightly sucking the copper-clad ceramic substrate. The output end of the rotary cylinder 76 is fixedly connected to the second connecting block 77, enabling the rotary cylinder 76 to drive the second connecting block 77 to rotate. The rotation of the second connecting block 77 drives the copper-clad ceramic substrate to rotate, thus completing the angle adjustment of the copper-clad ceramic substrate.

[0063] As Figure 2 and Figure 13 shown, the temporary storage mechanism 9 includes a second mounting frame 91, a transmission shaft 92, a gear 93, a fourth motor 94, a rack 95, a second bracket 96, and a second connecting rod 97. The second mounting frame 91 is fixedly connected to the first bracket 42. The transmission shaft 92 is rotatably connected to the second mounting frame 91. The gear 93 is keyway-connected to the transmission shaft 92. The fourth motor 94 is fixedly connected to the second mounting frame 91. The output end of the fourth motor 94 is fixedly connected to the transmission shaft 92. The rack 95 meshes with the gear 93. The rack 95 is fixedly connected to the second bracket 96. The second connecting rod 97 is fixedly connected to the second bracket 96.

[0064] The output end of the fourth motor 94 on the second mounting frame 91 is fixedly connected to the transmission shaft 92, enabling the fourth motor 94 to drive the transmission shaft 92 to rotate. The transmission shaft 92 and the gear 93 are keyway-connected, enabling the rotation of the transmission shaft 92 to drive the gear 93 to rotate. The rack 95 meshes with the gear 93, causing the rack 95 to move upward. The second bracket 96 is fixedly connected to the rack 95, enabling the second bracket 96 to move upward together with the rack 95. By providing the second connecting rod 97, the copper-clad ceramic substrate is placed on the second connecting rod 97. The second connecting rod 97 is fixedly connected to the second bracket 96, causing the second connecting rod 97 to rise, and the copper-clad ceramic substrate rises with the second connecting rod 97, thereby enabling the copper-clad ceramic substrate to leave the conveying mechanism 4, thus completing the temporary storage of the copper-clad ceramic substrate.

[0065] Working principle: The robotic arm 3 grabs the copper-clad ceramic substrate from the lamination cart 2 and places it on the rod 43. The third motor 41 drives the rod 43 to rotate, conveying the substrate in the processing direction. The lifting cylinder 52 drives the first limit plate 51 to rise, stopping the copper-clad ceramic substrate at the designated position. The double-acting cylinder 61 drives the first connecting rod 62 to approach the double-acting cylinder 61 simultaneously, causing the eight second limit plates 63 to approach each other in pairs, thereby performing centering adjustment on four copper-clad ceramic substrates simultaneously. The second lead screw module 71 drives the second mounting plate 72 to descend linearly, and the suction cup 78 tightly holds the copper-clad ceramic substrate. The rotary cylinder 76 rotates the copper-clad ceramic substrate, and the first limit plate 51 descends and moves away. The substrate is conveyed. The first motor 827 drives the unwinding reel 823 and the winding reel 826 to rotate, moving a new section of tape 824 onto the rotating shaft 825. The electric cylinder 821 is driven to lower the first mounting bracket 822, causing the tape 824 to contact the adhesive film on the copper-clad ceramic substrate. The electric cylinder 821 drives the first mounting bracket 822 to rise, causing the tape 824 to pick up the adhesive film. The second motor 834 drives the double lead screw 833 to rotate, moving the first clamping plate 835 towards the second clamping plate 836. The connecting slide plate 8371 drives the wedge block 8372 to push the second clamping plate 836 towards the first clamping plate 835. When both the first clamping plate 835 and the second clamping plate 836 contact the adhesive film, while the wedge block 8372 moves towards the second clamping plate 836, it also moves upward. The slide bar 8374 slides into the sliding groove 83721, and the spring 8375 compresses, generating an elastic force on the wedge block 8372, causing the wedge block 8372 to tightly press the second clamping plate 836, and further causing the second clamping plate 836 and the first clamping plate 835 to clamp the adhesive film. The substrate is conveyed and the film is torn off. The fourth motor 94 drives the transmission shaft 92 to rotate, causing the second bracket 96 to move upward together with the rack 95, and the copper-clad ceramic substrate parked on the second connecting rod 97 to rise with the second connecting rod 97, thereby causing the copper-clad ceramic substrate to leave the conveying mechanism 4, and thus completing the temporary storage of the copper-clad ceramic substrate.
