Description

Technical Field

[0001] The invention relates to the technical field of laminating equipment, in particular to a pre-treatment laminating equipment for copper clad circuit boards. Background Art

[0002] The lamination equipment of copper clad circuit boards generally refers to the equipment used to press the layers of materials of multi-layer circuit boards together. The core component of this lamination equipment is usually a pressing mechanism, which is used to press the prefabricated copper plate and substrate under high temperature and high pressure to form the structure of the multi-layer circuit board. The mold is used to provide the required board shape and pressure distribution during the pressing process to ensure that the layers of materials can be properly bonded and positioned.

[0003] The Chinese patent with announcement number CN115802628B discloses a lamination device and lamination process for copper-clad circuit boards, including a workbench and a mounting frame fixedly installed on the top of the workbench. By setting an orientation determination plate on the workbench and using a correction preheating component at the same time, the positions of the substrate and the copper plate are corrected and both are preheated. The copper plate stored in the copper plate storage box can be preheated in advance, and the copper-clad circuit board can be cooled in conjunction with the cold air flow of the vortex tube.

[0004] The Chinese patent with the announcement number CN111295061B discloses a thick copper circuit board lamination process and lamination device. During lamination, the glue of the prepreg will not fill the etched grooves in the circuit pattern, making the thickness of the board uniform. At the same time, the positioning column positions the substrate and the prepreg, and the substrate and the prepreg are accurately aligned, improving the lamination quality.

[0005] The above-mentioned and similar prior arts can solve the positioning and calibration problems of copper plates and substrates to a certain extent. However, when adding copper plates and substrates, the laminating equipment of the prior art needs to manually stack a group of copper plates and substrates on the heating table, and use molds and other positioning and calibration mechanisms to position and calibrate the stacked copper plates and substrates. After one group of lamination is completed, the next group is continued, which increases manpower consumption and reduces the degree of automation. In addition, the existing calibration structure for the copper plates and substrates needs to be completed before the lamination process, which means that the steps of the lamination process are increased, the work content is increased, and the work efficiency is reduced.

[0033] Specifically, the workbench 11 can provide stable support for the column 12, and the column 12 can provide stable support for all the components connected to it. The shell 13 can provide a shielding effect for the hot pressing block 15. At the same time, when the copper plate and the substrate enter the inner side of the shell 13, the copper plate and the substrate move downward under the guidance of the shell 13. The leakage hole on the top of the workbench 11 can provide a guiding effect for the copper plate and the substrate after the lamination process, so that the copper plate and the substrate move out of the workbench 11 along the position of the leakage hole. The hydraulic cylinder 14 can provide driving force for the hot pressing block 15, driving the hot pressing block 15 to rise and fall.

[0035] Specifically, the column 12 can provide a penetration space for the movable hole 23, and the movable hole 23 can provide a movable space for the gear 27 and the tooth plate 28.

The column 12 can provide a stable support for the protective shell, and the protective shell can provide protection for the meshing of the gear 27 and the tooth plate 28, thereby reducing external interference. At the same time, when the tooth plate 28 drives the L rod 29 to move, the penetration effect of the L rod 29 and the protective shell enables the protective shell to provide a limiting and guiding effect for the L rod 29. When the motor 26 drives the gear 27 to rotate, the gear 27 can be driven by the gear 27 to rotate. The tooth plate 28 and the L rod 29 are driven by the meshing action with the tooth plate 28, so that the L rod 29 drives the push plate 210 to move left and right, and the moving directions of the two push plates 210 are always opposite, so that the copper plates and substrates inside the placement frame 21 can be pushed out to the inside of the shell 13, and the shell 13 and the placement frame 21 can provide sliding support for the L plate 22, and the L plate 22 can provide placement space for the copper plates and substrates outside.

[0036] In this embodiment, the limit assembly 3 is equipped to support the copper plate and the substrate by a rotating plate 32 arranged at the bottom of the shell 13. When the hot pressing block 15 pushes the copper plate and the substrate downward, the copper plate and the substrate automatically calibrate their positions under the pressure of the rotating plate 32. The limit assembly 3 also includes four fixed seats 31. The four fixed seats 31 are respectively fixedly installed on the bottom of the shell 13 and are located in four directions of front, back, left and right. The rotating plate 32 is movably installed at the bottom of the fixed seat 31. A fixed tube 33 is fixedly installed on one side of the rotating plate 32. A spring 34 is placed on the inner side of the fixed tube 33. Guide rods 35 are respectively fixedly installed on both ends of the spring 34, and the guide rod 35 is located on the inner side of the fixed tube 33.

[0038] In this embodiment, a feeding mechanism 4 is provided on the top of the workbench 11, and the feeding mechanism 4 is equipped to feed the copper plate and the substrate after lamination. The feeding mechanism 4 includes a clamping assembly 5 and a reset assembly 6. The clamping assembly 5 is equipped to clamp and fix the descending hot pressing plate 54 through a limiting plate 57. The clamping assembly 5 includes a square groove 51, and the square groove 51 is opened on the top of the workbench 11. A plurality of springs 53 are fixedly installed at the bottom of the square groove 51.

A movable groove 52 is opened on the side of the square groove 51 close to the column 12, and the movable groove 52 is located at the bottom of the limiting groove 55. Two springs 56 are fixedly installed on the side of the movable groove 52 close to the column 12.

The workbench 11 can provide an opening space for the movable groove 52, and the movable groove 52 can provide a space for the placement and movement of the limit plate 57 and the spring three 56. When the hot pressing plate 54 moves downward under the action of external force to squeeze the spring two 53 and drive the limit groove 55 to move to be parallel to the movable groove 52, the limit plate 57 enters the inner side of the limit groove 55 under the action of the spring three 56 to fix the hot pressing plate 54. When the limit plate 57 moves out of the limit groove 55, the hot pressing plate 54 is reset under the action of the spring two 53.

[0040] In this embodiment, the reset assembly 6 is assembled to drive the hot pressing plate 54 to reset through the guiding action of the inclined plate 66 and the inclined hole 62. The reset assembly 6 includes two vertical holes 61, which are opened at the top of the workbench 11 and communicated with the movable groove 52. The inclined hole 62 runs through and is opened between the two vertical holes 61, and the inclined hole 62 communicates with the two vertical holes 61. Two square tubes 63 are fixedly installed on the top of the limit plate 57, and the two square tubes 63 are respectively located on the inner sides of the two vertical holes 61. Two springs 64 are fixedly installed on the top of the limit plate 57, and the two springs 64 are respectively located on the inner sides of the two square tubes 63. A movable plate 65 is fixedly installed on the other end of the spring four 64, and the movable plate 65 is located on the inner side of the square tube 63. The top of the movable plate 65 is an inclined surface. The inclined plate 66 is fixedly installed between the two movable plates 65, and the inclined plate 66 is located on the inner side of the inclined hole 62. An electric push rod 67 is fixedly installed inside the column 12. A push plate 68 is fixedly installed on the output end of the electric push rod 67, and the push plate 68 is located between the column 12 and the movable plate 65. Two guide rods 69 are fixedly installed on one side of the push plate 68. The two guide rods 69 are respectively located on both sides of the electric push rod 67, and the guide rod 69 runs through the interior of the column 12.

[0041] Specifically, the workbench 11 can provide a space for the vertical hole 61, the vertical hole 61 can provide a space for the square tube 63 and the movable plate 65 to be placed and moved, the square tube 63 can provide a space for the spring four 64 and the movable plate 65 to be placed and moved, the workbench 11 can provide a space for the inclined hole 62, the inclined hole 62 can provide a guide for the movement of the inclined plate 66, and the inclined plate 66 can provide a connecting support for the movable plate 65. When the movable plate 65 moves under the action of an external force, the movable plate 65 drives the limit plate 57 to move through the square tube 63, and the movable plate 65 drives the inclined plate 66 to move, so that the inclined plate 66 moves obliquely downward under the guidance of the inclined hole 62, so that the movable plate 65 gradually enters the inner side of the square tube 63 to squeeze the spring four 64. When the movable plate 65 loses the action of the external force, the spring three 56 drives the limit plate 57 to reset, so that the limit plate 57 drives the square tube 63 to reset, and the movable plate 65 is reset under the action of the spring four 64.

[0042] Working principle: the staff first places the device stably at the designated work location, and powers on the device, first starts the motor 26, so that the motor 26 drives the gear 27 to rotate through the transmission rod, and the gear 27 drives the two gear plates 28 to move in opposite directions by meshing with the gear plate 28, and the gear plate 28 drives the L rod 29 and the ejection plate 210 to move, so that the two ejection plates 210 move toward each other in the direction away from the housing 13, and move the ejection plates 210 out of the inner side of the placement frame 21;

[0043] Then, the two L plates 22 are grasped and moved toward the front, so that the L plates 22 slide out toward the front, and the two groups of copper plates and substrates are placed on the top of the L plates 22 respectively, and the L plates 22 are pushed back to the inner side of the placement frame 21, so that the L plates 22 drive the copper plate group and the substrate group to enter the inner side of the placement frame 21, and the motor 26 is started to rotate in the opposite direction again, so that the motor 26 drives the two push-out plates 210 to move toward the direction of the shell 13, so that the push-out plates 210 push the bottom copper plate and substrate in the copper plate group and the substrate group to the inner side of the shell 13, so that the copper plate is located at the top and the substrate is located at the bottom. The copper plate and the substrate fall downward along the shell 13 to the top of the rotating plate 32 under the action of their own gravity;

[0044] The hot pressing block 15 is powered on for heating, and the hydraulic cylinder 14 is started to push the hot pressing block 15 downward, so that the hot pressing block 15 moves to the top of the copper plate and pushes the copper plate and the substrate downward, so that the copper plate and the substrate move downward, and the rotating plate 32 rotates outward and opens under the extrusion of the copper plate and the substrate, and the rotating plate 32 drives the spring 1 34 to stretch through the fixed tube 33 and the guide rod 35. When the copper plate and the substrate move to the bottom of the rotating plate 32, the substrate contacts the top of the hot pressing plate 54. At this time, the rotating plate 32 rotates to a state perpendicular to the hot pressing plate 54, and the hot pressing block 15 continues to be extruded downward, so that the hot pressing block 15, the copper plate, the substrate and the hot pressing plate 54 move downward together, and the hot pressing plate 54 squeezes the spring 2 53 to be compressed. When the hot pressing plate 54 moves downward to the top and is parallel to the top of the workbench 11, the rotating plate 32 does not contact the copper plate and the substrate, but only contacts the hot pressing block 15. The hot pressing block 15 and the hot pressing plate 54 perform hot pressing treatment on the copper plate and the substrate for a period of time;

[0045] When the hot pressing plate 54 moves downward, the hot pressing plate 54 utilizes the resistance effect with the inclined surface of the limiting plate 57 to squeeze the limiting plate 57 to move to the inner side of the movable groove 52, and the limiting plate 57 squeezes the spring three 56 to be compressed and deformed. When the top of the hot pressing plate 54 is parallel to the top of the workbench 11, the hot pressing plate 54 drives the limiting groove 55 to move to the position of the movable groove 52, and the spring three 56 drives the limiting plate 57 to reset and enter the inner side of the limiting groove 55 under the action of its own elastic force;

[0046] When the hot pressing treatment is completed, the hydraulic cylinder 14 is started to drive the hot pressing block 15 to reset. When the hot pressing block 15 is not in contact with the rotating plate 32, the rotating plate 32 rotates and resets under the contraction of the spring 1 34, while the hot pressing plate 54 is not reset under the action of the limit plate 57 and remains parallel to the workbench 11.

[0047] Then, the electric push rod 67 is started, so that the electric push rod 67 drives the push plate 68 to move toward the front. When the push plate 68 passes the top of the movable plate 65, the push plate 68 uses the inclined surface with the top of the movable plate 65 to push the movable plate 65 to move downward, so that the movable plate 65 compresses the spring four 64 downward to deform. After the push plate 68 passes the movable plate 65, the movable plate 65 is reset under the action of the spring four 64, and the push plate 68 pushes the copper plate and the substrate after the heat pressing treatment to move toward the front, so that the copper plate and the substrate are unloaded along the leakage of the workbench 11;

[0048] Afterwards, the electric push rod 67 contracts and drives the push plate 68 to reset. When the push plate 68 contacts the movable plate 65 again, the push plate 68 drives the movable plate 65 to move to the back side. The movable plate 65 drives the limit plate 57 to move to the inner side of the movable groove 52 through the square tube 63, so that the limit plate 57 moves out of the inner side of the limit groove 55. The hot pressing plate 54 moves upward and resets under the action of the spring 2 53. At the same time, during the process of the push plate 68 driving the movable plate 65 to move, the movable plate 65 drives the inclined plate 66 along the inner side of the inclined groove, so that the inclined plate 66 reacts and drives the movable plate 65 to move obliquely downward, so that the movable plate 65 gradually enters the inner side of the square tube 63 downward. When the movable plate 65 moves obliquely downward to be lower than the push plate 68, the spring 3 56 drives the limit plate 57 to reset, and the spring 4 64 drives the movable plate 65 to reset, thereby resetting the entire device to its initial state.
