Description

Technical Field

[0001] The utility model relates to the technical field of PCB board processing, and specifically relates to a PCB board positioning device. Background Art

[0002] A PCB board is a basic component used to support and connect electronic components. A PCB board is usually made of an insulating material (usually glass fiber-reinforced epoxy resin), and is covered with conductive paths and connection points, which are called circuits and are used to transmit current, signals, and data in electronic devices.

[0003] When processing a PCB board, a positioning device is needed to avoid misalignment and movement during processes such as drilling and welding. However, the existing PCB board positioning devices can usually only fix PCB boards of specific sizes, with low applicability. And after the existing positioning devices fix the PCB board, they cannot adjust the angle of the PCB board, thus reducing the limitations of processing. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a PCB board positioning device that can fix PCB boards of different sizes and can adjust the angle of the PCB board.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A PCB board positioning device includes a placement board and a bottom board. On one side in the width direction of the upper surface of the placement board, a fixed block is installed, and a fixed support plate is installed on the top of the fixed block. On the other side in the width direction of the upper surface of the placement board, a movable block is installed through a first adjustment mechanism, and a positioning support plate is installed on the top of the movable block. On both sides in the length direction of the upper surface of the placement board, clamping blocks are slidably installed, and clamping support plates are installed on the opposite surfaces of the two clamping blocks through a second adjustment mechanism. On the opposite surfaces of the two clamping blocks, connecting plates are installed, and the long arms of the connecting plates extend to the lower side of the placement board. At the ends of the long arms of the two connecting plates, wedge-shaped blocks are installed. On the lower surface of the placement board, a U-shaped mounting frame is installed, and an electric push rod is installed inside the U-shaped mounting frame. At the end of the telescopic end of the electric push rod, a V-shaped block is installed. On the upper surface of the bottom board, a rotation mechanism is provided that can drive the U-shaped mounting frame to rotate.

[0007] It can be seen that the electric push rod drives the V-shaped block to squeeze the two wedge-shaped blocks, and then can drive the two clamping pallets to move inward simultaneously, clamping and fixing both sides of the PCB board. By adjusting the position of the clamping pallets through the second adjustment mechanism, the purpose of fixing PCB boards of different sizes can be achieved. Through the setting of the positioning pallet, it can play a positioning role when placing the PCB board, ensuring that the PCB board can be fixed at the accurate position, improving the processing accuracy. And through the setting of the first adjustment mechanism, the position of the positioning pallet can be adjusted, and thus it can play a positioning role when fixing PCB boards of different sizes, with a wide range of applications. Through the setting of the rotation mechanism, the angle of the PCB board can be adjusted during the processing, improving the processing range and flexibility. The electric push rod adjusts the position of the second adjustment structure in the width direction through the connecting plate and the clamping block, and adjusts the opening and closing of the clamping pallets. The clamping center of the clamping pallets can be adjusted through the second adjustment mechanism. The overall structure is compact, which is beneficial to the miniaturization of the equipment.

[0008] Furthermore, the first adjustment mechanism includes an installation groove opened on the upper surface of the placement board. A first threaded rod is rotatably installed inside the installation groove. A nut seat is installed on the outer surface of the first threaded rod, and the upper surface of the nut seat is connected to the lower surface of the movable block.

[0009] When it is necessary to adjust the position of the positioning pallet, the first threaded rod can be rotated. Since the inner wall of the installation groove limits the nut seat, the nut seat can move along its length direction when the first threaded rod rotates, and the position of the positioning pallet can be adjusted through the movable block.

[0010] Furthermore, the second adjustment mechanism includes two guide rods connected to the outer surface of the clamping pallet. The ends of the two guide rods both penetrate to the other side of the clamping block and are jointly installed with an adjustment plate. A second threaded rod penetrates and is threadedly connected inside the adjustment plate, and the end of the second threaded rod is rotatably connected to the clamping block.

[0011] When it is necessary to adjust the position of the clamping pallet, the second threaded rod can be rotated to drive the adjustment plate to move along its length direction, and through the connection of the guide rods, the purpose of driving the clamping pallet to move back and forth can be achieved.

[0012] Furthermore, the rotation mechanism includes a connecting shaft rotatably installed on the upper surface of the bottom plate. The top of the connecting shaft is connected to the lower surface of the U-shaped installation frame. A worm gear is sleeved on the outer surface of the connecting shaft. Two side plates are installed on the upper surface of the bottom plate. A worm is rotatably connected between the two side plates, and the worm is meshed with the worm gear. A motor is installed on the outer surface of one of the side plates, and the output shaft of the motor is connected to the worm.

[0013] When it is necessary to adjust the angle of the PCB board, the motor can be started to drive the worm to rotate. Due to the meshing of the worm and the worm gear, the connecting shaft can be driven to rotate, and the purpose of driving the PCB board to rotate can be achieved.

[0014] Further, two limiting sleeves are installed on the lower surface of the placement plate, and the long arm of the connecting plate is slidably arranged in the limiting sleeves.

[0015] Through the arrangement of the limiting sleeves, the connecting plate can be limited, improving the structural stability thereof.

[0016] Further, balls are evenly installed on the inclined surface of the wedge block.

[0017] Through the arrangement of the balls, the frictional resistance between the V-shaped block and the wedge block can be reduced, making the two clamping support plates more smooth and stable when clamping and fixing the PCB board. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The present utility model will be described in detail below with reference to the accompanying drawings.

[0025] As Figures 1-5As shown in the figure, a PCB board positioning device includes a placement board 100 and a bottom board 112. On one side of the upper surface of the placement board 100 in the width direction, a fixed block 101 is installed. On the top of the fixed block 101, a fixed support plate 102 is installed. On the other side of the upper surface of the placement board 100 in the width direction, a movable block 103 is installed through a first adjustment mechanism 200. On the top of the movable block 103, a positioning support plate 104 is installed. On both sides of the upper surface of the placement board 100 in the length direction, clamping blocks 105 are slidably installed. On the opposite surfaces of the two clamping blocks 105, clamping support plates 106 are installed through a second adjustment mechanism 300. On the opposite surfaces of the two clamping blocks 105, connecting plates 107 are installed, and the long arms of the connecting plates 107 extend to the lower side of the placement board 100. At the ends of the long arms of the two connecting plates 107, wedge-shaped blocks 108 are installed. On the lower surface of the placement board 100, a U-shaped mounting frame 109 is installed. Inside the U-shaped mounting frame 109, an electric push rod 110 is installed. At the end of the telescopic end of the electric push rod 110, a V-shaped block 111 is installed. On the upper surface of the bottom board 112, a rotation mechanism 400 capable of driving the U-shaped mounting frame 109 to rotate is provided.

[0026] When in use, first adjust the position of the positioning support plate 104 through the first adjustment mechanism 200, and adjust the position of the clamping support plate 106 through the second adjustment mechanism 300. Then place the PCB board on the fixed support plate 102, the positioning support plate 104, and the two clamping support plates 106. At this time, the fixed support plate 102 and the positioning support plate 104 limit the PCB board in the width direction, and there are certain gaps between the two sides of the PCB board in the length direction and the inner walls of the two clamping support plates 106 respectively. Subsequently, start the electric push rod 110. The telescopic end of the electric push rod 110 drives the V-shaped block 111 to move upward. The inner walls on both sides of the V-shaped block 111 respectively squeeze the inclined surfaces of the two wedge-shaped blocks 108, thereby driving the two connecting plates 107 to move inward simultaneously, and driving the clamping support plates 106 to move through the clamping blocks 105, so that the inner walls of the two clamping support plates 106 are in contact with the two sides of the PCB board in the length direction and are tightened, achieving the purpose of fixation. And during the processing, the angle of the PCB board can be adjusted through the rotation mechanism 400 to improve the processing range and flexibility.

[0027] Specifically, the first adjustment mechanism 200 includes a mounting groove 201 opened on the upper surface of the placement board 100. Inside the mounting groove 201, a first threaded rod 202 is rotatably installed. On the outer surface of the first threaded rod 202, a nut seat 203 is installed, and the upper surface of the nut seat 203 is connected to the lower surface of the movable block 103. When it is necessary to adjust the position of the positioning support plate 104, the first threaded rod 202 can be rotated. Since the inner wall of the mounting groove 201 limits the nut seat 203, the nut seat 203 can move along the length direction of the first threaded rod 202 when the first threaded rod 202 rotates, and the position of the positioning support plate 104 can be adjusted through the movable block 103.

[0028] Specifically, the second adjustment mechanism 300 includes two guide rods 301 connected to the outer surface of the clamping support plate 106. The ends of the two guide rods 301 penetrate to the other side of the clamping block 105 and are jointly installed with an adjustment plate 302. A second threaded rod 303 penetrates and is threadedly connected inside the adjustment plate 302, and the end of the second threaded rod 303 is rotatably connected to the clamping block 105. When it is necessary to adjust the position of the clamping support plate 106, the second threaded rod 303 can be rotated to drive the adjustment plate 302 to move along its length direction, and through the connection of the guide rods 301, the purpose of driving the clamping support plate 106 to move back and forth can be achieved.

[0029] Specifically, the rotation mechanism 400 includes a connecting shaft 401 rotatably installed on the upper surface of the bottom plate 112, and the top of the connecting shaft 401 is connected to the lower surface of the U-shaped mounting frame 109. A worm gear 402 is sleeved on the outer surface of the connecting shaft 401. Two side plates 403 are installed on the upper surface of the bottom plate 112. A worm 404 is rotatably connected between the two side plates 403, and the worm 404 is meshed with the worm gear 402. A motor 405 is installed on the outer surface of one of the side plates 403, and the output shaft of the motor 405 is connected to the worm 404. When it is necessary to adjust the angle of the PCB board, the motor 405 can be started to drive the worm 404 to rotate. Due to the meshing of the worm 404 and the worm gear 402, the connecting shaft 401 can be driven to rotate, and the purpose of driving the PCB board to rotate can be achieved.

[0030] Specifically, two limit sleeves 500 are installed on the lower surface of the placement plate 100. The long arm of the connecting plate 107 is slidably arranged in the limit sleeves 500. Through the arrangement of the limit sleeves 500, the connecting plate 107 can be limited, and the structural stability can be improved.

[0031] Specifically, balls 600 are evenly installed on the inclined surface of the wedge block 108. Through the arrangement of the balls 600, the frictional resistance between the V-shaped block 111 and the wedge block 108 can be reduced, so that when the two clamping support plates 106 clamp and fix the PCB board, it is more smooth and stable.

[0032] The above is a detailed description of the present invention in combination with specific embodiments. It cannot be determined that the specific implementation manners of the present invention are only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several equivalent substitutions or obvious modifications are made, and the performance or use is the same, and all should be regarded as belonging to the patent protection scope determined by the claims submitted by the present invention.
