Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, specifically a PCB board pressing and positioning device. Background Technology

[0002] PCB stands for Printed Circuit Board, also known as Printed Circuit Board. It is an important electronic component, serving as the support for electronic components and the carrier for electrical interconnection between them. Because it is made using electronic printing technology, it is called a "printed" circuit board. During the manufacturing process, multiple conductive layers need to be laid on the circuit board. Therefore, positioning devices are needed to position and fix each layer of the circuit board during the manufacturing process to ensure safety and stability in the subsequent lamination process and avoid deviations.

[0003] According to Chinese patent document CN219248200U, a PCB board lamination and positioning device includes a base, a rotating component mounted on the upper surface of the base, a processing table mounted on the rotating component, a positioning component mounted on the processing table, and a PCB board body mounted on the upper surface of the processing table. The positioning component can position and fix the PCB board body, and a clamping component is mounted on the back of the processing table. This invention uses the positioning component to position and fix the PCB board substrate, and the rotating component can synchronously link the processing table and the PCB board body on it to rotate, facilitating quick adaptation to different processing equipment for coordinated use. Simultaneously, the clamping component is hidden on the processing table; after each layer of the PCB is laid on the surface of the PCB board body, the clamping component can stably press and adhere the edges of that layer, preventing problems such as curling and wrinkles in the gaps between adjacent layers.

[0004] However, in use, the pressing roller of the above device cannot move along its axial direction, making it unsuitable for PCB boards of different areas. Furthermore, when the pressing roller moves downwards, it interferes with the L-shaped baffle, the first pressure plate, and the second pressure plate, preventing it from entering the area enclosed by these components. Therefore, a PCB board pressing and positioning device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a PCB board pressing and positioning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PCB board pressing and positioning device, comprising a base, a rotating column rotatably mounted on the upper end of the base, a worktable fixedly mounted on the upper end of the rotating column, a driving mechanism acting on the rotating column on the base, an L-shaped plate fixedly mounted on the upper edge of the worktable, a first clamping plate and a second clamping plate also provided on the upper surface of the worktable, the bottom of the first clamping plate being movable relative to the worktable via a first adjusting mechanism, the bottom of the second clamping plate being movable relative to the worktable via a second adjusting mechanism, an mounting plate fixedly mounted on the side wall of the worktable, a first cylinder provided on the upper surface of the mounting plate, the bottom of the first cylinder being movable relative to the mounting plate via a third adjusting mechanism, a fixed plate fixedly connected to the end of the telescopic rod of the first cylinder, a second cylinder fixedly mounted on the side wall of the fixed plate away from the worktable, the telescopic rod of the second cylinder penetrating the fixed plate and fixedly connected to an L-shaped rod, a U-shaped plate fixedly connected to the end of the L-shaped rod, and a pressure roller rotatably connected between the two parallel plates of the U-shaped plate.

[0007] As a further preferred embodiment of this technical solution, the first clamping plate, the second clamping plate, and the L-shaped plate are arranged in a rectangular shape.

[0008] As a further preferred embodiment of this technical solution, the first adjustment mechanism, the second adjustment mechanism, and the third adjustment mechanism are identical in structure.

[0009] As a further preferred embodiment of this technical solution, the third adjustment mechanism consists of an adjustment screw, a slider, and a first motor. The slider is slidably installed in a groove formed on the upper surface of the mounting plate. An adjustment screw is provided in the groove. The slider is threaded onto the outer surface of the adjustment screw. The two ends of the adjustment screw are rotatably connected to the two inner walls of the groove, respectively. The first motor is fixedly installed on the outer wall of the mounting plate, and the output shaft of the first motor is fixedly connected to the adjustment screw.

[0010] As a further preferred embodiment of this technical solution, the driving mechanism consists of a worm gear, a fixed vertical plate, a second motor, and a worm. A worm gear is fixedly sleeved on the outer wall of the rotating column, and a worm is provided on the side of the worm gear. The worm and the worm gear mesh with each other. Fixed vertical plates are rotatably connected to both ends of the worm. A second motor is fixedly installed on the side wall of one of the fixed vertical plates, and the output shaft of the second motor is fixedly connected to the worm.

[0011] As a further preferred embodiment of this technical solution, the radius of the pressure roller is less than 2cm.

[0012] As a further preferred embodiment of this technical solution, the thickness of the vertical plate of the U-shaped plate is less than 2cm.

[0013] This utility model provides a PCB board pressing and positioning device, which has the following beneficial effects:

[0014] This utility model can control the movement of the first clamping plate and the second clamping plate on the worktable through the first adjustment mechanism and the second adjustment mechanism, so that the rectangular area enclosed by the first clamping plate, the second clamping plate and the L-shaped plate is equal to that of the PCB board, thereby enabling the positioning of each layer of the PCB board.

[0015] The first cylinder can control the height of the pressure roller, and the third adjustment mechanism can control the lateral movement of the pressure roller. Through the cooperation of the first cylinder and the third adjustment mechanism, the pressure roller can be controlled to compact each layer of the PCB board, thereby avoiding wrinkles at the edges of each layer of the PCB board.

[0016] The L-shaped rod ensures that the first clamping plate, the second clamping plate, and the L-shaped plate do not interfere with the pressure roller. The second cylinder controls the pressure roller to move along its axial direction, thereby controlling the pressure roller to compact the PCB board from different positions. This makes the compaction area of ​​the pressure roller adjustable, enabling the compaction of PCB boards of different sizes. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1 to 4As shown, in this embodiment, a PCB board pressing and positioning device includes a base 1, a rotating column 20 rotatably mounted on the upper end of the base 1, a worktable 2 fixedly mounted on the upper end of the rotating column 20, a driving mechanism acting on the rotating column 20 on the base 1, an L-shaped plate 3 fixedly mounted on the upper edge of the worktable 2, and a first clamping plate 4 and a second clamping plate 5 also provided on the upper surface of the worktable 2. The first clamping plate 4, the second clamping plate 5, and the L-shaped plate 3 are arranged in a rectangular pattern. The bottom of the first clamping plate 4 moves relative to the worktable 2 through a first adjusting mechanism 6, and the bottom of the second clamping plate 5 moves relative to the worktable 2 through a second adjusting mechanism 7. A mounting plate 9 is fixedly installed on the side wall. A first cylinder 14 is provided on the upper surface of the mounting plate 9. The bottom of the first cylinder 14 moves relative to the mounting plate 9 through a third adjusting mechanism 8. The first adjusting mechanism 6, the second adjusting mechanism 7, and the third adjusting mechanism 8 have the same mechanism. A fixed plate 15 is fixedly connected to the end of the telescopic rod of the first cylinder 14. A second cylinder 16 is fixedly installed on the side wall of the fixed plate 15 away from the worktable 2. The telescopic rod of the second cylinder 16 passes through the fixed plate 15 and is fixedly connected to an L-shaped rod 17. A U-shaped plate 18 is fixedly connected to the end of the L-shaped rod 17. A pressure roller 19 is rotatably connected between the two parallel plates of the U-shaped plate 18.

[0024] The third adjustment mechanism 8 consists of an adjustment screw 10, a slider 11, and a first motor 13 (the third adjustment mechanism 8 is described here as an example; the first adjustment mechanism 6 and the second adjustment mechanism 7 have the same structure and will not be described further). The slider 11 is slidably installed in a groove 12 opened on the upper surface of the mounting plate 9. The adjustment screw 10 is provided in the groove 12. The slider 11 is threaded onto the outer surface of the adjustment screw 10. The two ends of the adjustment screw 10 are rotatably connected to the two inner walls of the groove 12. The first motor 13 is fixedly installed on the outer wall of the mounting plate 9. The output shaft of the first motor 13 is fixedly connected to the adjustment screw 10.

[0025] When in use, the first motor 13 is started to drive the adjusting screw 10 to rotate, thereby causing the slider 11 to slide in the slide groove 12.

[0026] The drive mechanism consists of a worm gear 21, a fixed vertical plate 22, a second motor 23, and a worm 24. The worm gear 21 is fixedly sleeved on the outer wall of the rotating column 20. The worm 24 is arranged on the side of the worm gear 21 and meshes with the worm gear 21. The two ends of the worm 24 are respectively rotatably connected to the fixed vertical plate 22. The second motor 23 is fixedly installed on the side wall of one of the fixed vertical plates 22. The output shaft of the second motor 23 is fixedly connected to the worm 24.

[0027] In use, the second motor 23 is started to drive the worm gear 24 to rotate, which in turn drives the worm wheel 21 to rotate, which in turn drives the rotating column 20 to rotate. The rotating column 20 will drive the worktable 2 to rotate, which can drive the PCB board on the worktable 2 to rotate, thus making it convenient for the staff to debug the PCB board from different angles.

[0028] Among them, the radius of the pressure roller 19 is less than 2cm, and the thickness of the vertical plate of the U-shaped plate 18 is less than 2cm.

[0029] Within the rectangular area enclosed by the first clamping plate 4, the second clamping plate 5, and the L-shaped plate 3, when the pressure roller 19 presses each layer of the PCB board, due to the obstruction of the first clamping plate 4, the second clamping plate 5, and the L-shaped plate 3, the pressure roller 19 is destined not to touch the very edge of each layer of the PCB board. However, the radius of the pressure roller 19 is less than 2cm, and the vertical plate thickness of the U-shaped plate 18 is less than 2cm, which can ensure that the pressure roller 19 can press down to a position 2cm away from the edge of each layer of the PCB board. Pressing down to this position is sufficient to ensure that no wrinkles appear at the edge of each layer of the PCB board.

[0030] This utility model provides a PCB board pressing and positioning device, the specific working principle of which is as follows:

[0031] In use, the first adjustment mechanism 6 and the second adjustment mechanism 7 can control the movement of the first clamping plate 4 and the second clamping plate 5 on the worktable 2 so that the rectangular area enclosed by the first clamping plate 4, the second clamping plate 5 and the L-shaped plate 3 is equal to that of the PCB board, thereby enabling the positioning of each layer of the PCB board.

[0032] The first cylinder 14 can control the height of the pressure roller 19, and the third adjustment mechanism 8 can control the lateral movement of the pressure roller 19. Through the cooperation of the first cylinder 14 and the third adjustment mechanism 8, the pressure roller 19 is controlled to compact the PCB layer after each layer is placed, thereby avoiding wrinkles at the edges of each layer of the PCB. The L-shaped rod 17 can ensure that the first clamping plate 4, the second clamping plate 5 and the L-shaped plate 3 will not interfere with the pressure roller 19.

[0033] The second cylinder 16 can control the pressure roller 19 to move along its axial direction, thereby controlling the pressure roller 19 to compact the PCB board multiple times from different positions, so that the compaction area of ​​the pressure roller 19 is adjustable and can compact PCB boards of different areas.

[0034] After all layers of the PCB board are laid out, the PCB board can be hot-pressed using an external hot-pressing device.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
