Abstract
Description
Technical Field
[0001] This utility model relates to the field of printed circuit board technology, and in particular to a correction mechanism compatible with single and double core boards. Background Technology
[0002] In the field of printed circuit board (PCB) manufacturing, the lamination process of multilayer core boards requires precise positioning to achieve alignment and correction between layers. Traditional correction mechanisms typically employ a fixed stop structure, where the position of the stop is adjusted manually or through simple mechanical drives to confine the core board to the center of the platform for single-board correction. However, such mechanisms have significant limitations: First, the fixed stop layout can only accommodate core boards of a single size. When processing core boards of different specifications or double-layer core boards, frequent adjustments or replacements of equipment are required, resulting in low efficiency and cumbersome operation. Second, traditional mechanisms lack dynamic partitioning capabilities, making it impossible to flexibly switch between single-layer and double-layer core board correction modes, thus failing to meet diverse production needs. Third, the transmission components often use asynchronous drive methods, which can easily cause positional deviations when the stop moves, affecting the positioning accuracy of the core board and consequently reducing the yield of finished products.

[0036] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0037] See Figures 1-4 This utility model embodiment proposes a correction mechanism compatible with single and double core boards, including:
[0038] Platform 1, with a through hole 10 in its middle;
[0039] The calibration component 2 is disposed on the platform 1 and includes two first calibration components 20 symmetrically arranged along the length direction of the platform 1 and two second calibration components 21 symmetrically arranged along the width direction of the platform 1. The first calibration component 20 and the second calibration component 21 each have a calibration reference plane perpendicular to the plane of the platform 1. The first calibration component 20 and the second calibration component 21 enclose a cavity that can accommodate a single core board or a double core board.
[0040] The dividing component 3 includes a driving member 30 and a baffle 31 with a through hole 10. The baffle 31 has a first state of retracting below the plane of the platform 1 and a second state of extending above the plane of the platform 1. The driving member 30 drives the baffle 31 to switch between the two states to divide the chamber into two independent correction areas or merge them into a single correction area.
[0041] The transmission assembly 4 includes a first transmission member 41 and a second transmission member 42. The first transmission member 41 drives the first correction member 20 to move closer to or away from the baffle 31, and the second transmission member 42 drives the second correction member 21 to move closer to or away from the baffle 31.
[0042] Platform 1 can be placed on a flat surface of a fixed structure such as a workbench. Platform 1 has a flat surface for placing the core board. A through hole 10 is cut in the middle of platform 1 for raising and lowering the baffle 31. Under the action of the drive assembly, the baffle 31 can extend out of the plane of platform 1, thereby dividing the plane of platform 1 into two correction areas, which can be used to correct one type of core board or two types of core boards of the same size. When correcting core boards of different sizes, it is achieved by correction assembly 2, which includes two first correction members 20 and two second correction members 21. The two first correction members 20 are arranged along the length direction of platform 1 and can move along the width direction of platform 1 under the drive of the first transmission member 41. The two second correction members 21 are arranged along the length direction of the flat plate and can move along the length direction of platform 1 under the drive of the second transmission member 42. That is to say, the first correction members 20 and the second correction members 21 move closer to or further away from the baffle 31 under the drive of the transmission assembly 4 to adjust the area of the chamber and thus adapt to core boards of different sizes. Meanwhile, to avoid motion interference between the first corrector 20 and the second corrector 21, the second corrector 21, arranged along the width direction of the platform 1, is located between the two first corrector 20s. Both the first corrector 20 and the second corrector 21 have a corrective base surface perpendicular to the plane of the platform 1. Their cooperation allows for the correction of a single core board. The cooperation of the first corrector 20, the second corrector 21, and the baffle 31 allows for the simultaneous correction of two core boards. In specific implementation, the first corrector 20 and the second corrector 21 can move on the plane of the platform 1, or longitudinal and transverse holes 131 can be drilled in the platform 1, through which the first corrector 20 and the second corrector 21 are respectively inserted.
[0043] The calibration mechanism compatible with single and double core boards provided by this utility model solves the core problems of low efficiency and poor applicability of traditional calibration mechanisms through dynamic partitioning of the dividing component 3, synchronous control of the transmission component 4, adjustable size of the chamber and modular design. It achieves the comprehensive benefits of seamless switching between single and double modes, high-precision calibration, multi-specification compatibility and low-cost operation and maintenance, and significantly improves the intelligence level and economic benefits of the production line.
[0044] The present invention further proposes that the platform 1 includes a base plate 11, a plurality of support columns 12 vertically disposed on the base plate 11, and a bearing plate 13 horizontally disposed on the top of the support columns 12. The bearing plate 13 is a flat plate structure, and the through hole 10 is provided in the middle of the bearing plate 13.
[0045] Specifically, the base plate 11, support column 12 and bearing plate 13 can all be made of plastic or metal. The bearing plate 13 forms a sandwich cavity with the base plate 11 through the support column 12. The drive unit 30 is installed in the sandwich cavity to ensure that the base plate 11 can be placed horizontally on the plane of a fixed structure such as the equipment workbench. The through hole 10 design simplifies the lifting path of the baffle 31 and ensures smooth dividing action.
[0046] The present invention further proposes that the support plate 13 is provided with a plurality of horizontal strip holes 130 extending along the length direction and a plurality of vertical strip holes 131 extending along the width direction.
[0047] The first correction component 20 includes a plurality of first blocks arranged side by side, each first block having a longitudinal strip hole 131 passing through it;
[0048] The second correction element 21 includes a plurality of second blocks arranged in parallel, each second block having a horizontal bar hole 130 through it.
[0049] Specifically, the bearing plate 13 is provided with a number of equally spaced horizontal strip holes 130 (along the length direction) and 4 vertical strip holes 131 (along the width direction). The first stop block and the second stop block are respectively inserted into the vertical strip holes 131 and the horizontal strip holes 130, and the purpose of adjusting the size of the chamber is achieved under the drive of the transmission component 4.
[0050] The present invention further proposes that the first transmission component 41 includes a drive motor 410, a pulley set 411, a synchronous belt 412 and two long blocks 413. The synchronous belt 412 is connected to the drive motor 410 through the pulley set 411. The two first correction components 20 are respectively connected to one long block 413, and the two long blocks 413 are respectively connected to the opposite sides of the synchronous belt 412, so that the two first correction components 20 simultaneously move closer to or further away from the baffle 31.
[0051] The second transmission component 42 has the same structure as the first transmission component 41.
[0052] The second transmission component 42 has the same structure as the first transmission component 41, meaning that the first transmission component 41 has the same parts as the second transmission component 42, but there are differences in appearance. The horizontal bar holes 130 and the vertical bar holes 131 are arranged in a multi-stop layout, which can flexibly adjust the size of the correction area to adapt to different specifications of core boards. The stop hole design reduces motion interference and improves correction accuracy.
[0053] In another possible implementation, the first transmission member 41 and the second transmission member 42 can also be synchronously reversed by using a ball screw transmission method. Specifically, the ball screw is provided with two transmission nuts, which are located at the two ends of the ball screw respectively, and the threads of the ball screw turn in opposite directions from the middle to the two ends.
[0054] This utility model further proposes that the driving component 30 includes any one of a first cylinder, a servo motor, and a linear motor.
[0055] Furthermore, if the driving component 30 is the first cylinder, the output shaft of the first cylinder is connected to the baffle 31;
[0056] If the driving component 30 is a servo motor, the rotating shaft of the servo motor is provided with a gear, the base plate 11 is vertically provided with a guide rail, a slider is slidably connected on the guide rail, the slider is provided with a rack that meshes with the gear, and the baffle 31 is connected to the slider.
[0057] If the driving component 30 is a linear motor, the stator of the linear motor is mounted on the base plate 11, and the mover is connected to the baffle 31. The driving component 30 is available in various types (cylinder, servo motor, linear motor) to meet the needs of different scenarios. Cylinder drives are low-cost and simple in structure, servo motors have high control precision and are suitable for high-requirement calibration, and linear motors have fast response and long lifespan.
[0058] This utility model further proposes that the top of the baffle 31 is provided with a guide slope, which cooperates with the through hole 10. The guide slope at the top of the baffle 31 cooperates with the through hole 10 to avoid jamming or collision during the lifting and lowering process, thereby enhancing operational safety. The guide slope at the top of the baffle 31 forms a 45° angle with the horizontal plane, and the edge of the through hole 10 is provided with a chamfer. The gap between the slope and the chamfer is 0.5mm to ensure that the baffle 31 is not blocked when lifting and lowering.
[0059] Based on the above specific embodiments, the baffle 31 can be designed as a U-shaped structure, and its material can be aluminum alloy or plastic materials such as polycarbonate. The opening direction of the U-shaped baffle 31 faces upward, which can effectively absorb and buffer the impact force generated when the correction assembly 2 moves the core plate, thereby protecting the core plate from damage. The number of baffles 31 can be one or more, and their extension length along the width direction of the support plate 13 can be set to the shortest distance between two first correction members 20. The longer the length of the baffle 31, the larger the correction reference surface in contact with the core plate, which will help to complete the correction work more accurately.
[0060] This invention further proposes that the first correction component 20, the second correction component 21, and the baffle 31 are all provided with a flexible buffer layer on their correction reference surfaces. The flexible buffer layer (such as rubber or silicone) reduces rigid contact with the core board, prevents the outer surface of the core board from having a notch, and improves the quality of the finished product. The flexible buffer layer is a silicone layer with a thickness of 2mm and a Shore hardness of 50A.
[0061] Furthermore, to simplify the structure of the calibration component 2, reduce the failure rate, and facilitate component replacement, this utility model also proposes another transmission method for the calibration component 2. In this method, the first calibration member 20 includes a first plate (not shown), the first transmission member 41 is a second cylinder, the second cylinder is mounted on the platform 1, and the output shaft of the second cylinder is connected to the first plate to drive the first plate to move closer to or away from the baffle 31. Simultaneously, the second calibration member 21 is a second plate (not shown), the second transmission member 42 is a third cylinder, and the two second plates are located between the two first plates.
[0062] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
