Description

Technical Field

[0001] This utility model relates to the field of printed circuit board manufacturing and processing technology, and in particular to a positioning mechanism for milling and forming printed circuit boards. Background Technology

[0002] Printed circuit boards (PCBs) are important electronic components. They serve as the support for electronic components and the carrier for their electrical interconnection. Because they are made using electronic printing technology, they are called "printed" circuit boards. In the production and processing of PCBs, milling is an essential and crucial step in the PCB manufacturing process. It plays an indispensable role in the assembly of finished PCBs. Therefore, PCB milling devices are used to process PCBs.

[0003] Existing technologies, such as patent CN213196458U, disclose a protective device for multi-drill circuit board milling. This patent uses a support bracket, with a primary protective plate fixedly installed at an angle on the outer side of the support bracket. Milling brackets are fixedly installed on the inner and outer sides of the upper outer end of the support bracket, and secondary protective plates are fixedly installed at the inner and outer sides of the outer outer end of the support bracket. A reinforcing crossbar is horizontally fixedly installed at the lower inner end of the stabilizing leg. A dust collection fan is fixedly installed at the bottom of the waste chip collection box, and a cleaning drawer is movably installed inside the waste chip collection box. A processing drill bit is movably installed on the upper outer end of the milling bracket. This utility model device solves the problem that most existing milling processing devices have relatively poor overall protection against waste chips generated during actual use, resulting in generally poor overall performance and efficiency. Furthermore, due to their structural limitations, waste chips entering the milling mechanism can easily shorten the overall service life.

[0004] In daily operation, the equipment has difficulty positioning circuit boards of different sizes and models, which limits its ability to process circuit boards. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where equipment struggles to position different types of circuit boards, and to propose a positioning mechanism for milling and forming printed circuit boards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a positioning mechanism for milling and forming printed circuit boards, comprising a placement plate, a mounting frame, a grinder, a connecting arm, and a moving plate. The connecting arm is fixedly connected to the side of the placement plate, the mounting frame is fixedly connected to the upper lower surface of the connecting arm, the moving plate is disposed below the mounting frame, the grinder is disposed on the lower surface of the moving plate, and a positioning device is disposed on the upper surface of the placement plate. The positioning device comprises a mounting plate and a circuit board. The mounting plate is disposed on the upper surface of the placement plate, the circuit board is disposed above the mounting plate, and a mounting groove is formed on the upper surface of the mounting plate. A support block is disposed inside the mounting groove, the support block is disposed inside the circuit board, and a pressure groove is formed inside the support block.

[0007] Furthermore, a limiting block is provided inside the pressure groove. One end of the limiting block is engaged with the inside of the mounting groove. By setting the limiting block, the support block can be limited, reducing the possibility that the support block may easily detach from the mounting plate during use, making it difficult to fix the support block inside the mounting plate.

[0008] Furthermore, a pressure rod is fixedly connected to the upper surface of the end of the limiting block away from the limiting groove. The pressure rod is slidably connected to the inside of the pressure groove. The pressure rod is provided to facilitate the movement of the limiting block.

[0009] Furthermore, a first spring is fixedly connected to one end of the limiting block near the pressure rod, and the end of the first spring away from the limiting block is fixedly connected to the inside of the pressure groove. The first spring is provided to facilitate the application of a reset force to the limiting block.

[0010] Furthermore, an auxiliary component is provided on the side of the placement plate near the connecting arm. The auxiliary component includes a positioning block and a connecting plate. The positioning block is disposed inside the mounting plate. The connecting plate is fixedly connected to one end of the positioning block. The side of the placement plate is fixedly connected to the positioning plate. A sliding rod is fixedly connected inside the positioning plate. The sliding rod is disposed inside the connecting plate. A threaded rod is rotatably connected to the inside of the positioning plate. The threaded rod is rotatably connected inside the connecting plate. A nut is fixedly connected to the surface of the connecting plate. By setting the positioning block, the mounting plate can be fixed, reducing the difficulty of fixing the mounting plate to the surface of the placement plate during equipment use.

[0011] Furthermore, the threaded rod is internally threaded to the nut, and a motor is fixedly connected to one end of the threaded rod. The threaded rod facilitates the movement of the connecting plate.

[0012] Furthermore, a connecting seat is fixedly connected to the surface of the motor, and the connecting seat is fixedly connected to the side of the placement plate. The connecting seat is provided to facilitate the limiting of the motor.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a positioning device, when the user presses the pressure rod during use, the pressure rod moves, causing the limiting block to move. When the limiting block moves, it causes the first spring to deform and generate elastic force. Subsequently, the limiting block moves and disengages from the interior of the mounting groove, and the support block is released from its restraint. By setting a positioning device, the circuit board is effectively positioned, playing a supporting and positioning role. In general, it is difficult for the equipment to position circuit boards of different sizes and models during use, resulting in limitations in the processing of circuit boards. This positioning device, through the cooperation between components such as the mounting plate, support block, limiting block, and first spring, can effectively position and support circuit boards of different models, improving the stability of the equipment.

[0015] 2. In this utility model, by setting an auxiliary component, when the user starts the motor, the motor rotates and drives the threaded rod to move the nut. When the nut moves, it drives the connecting plate to move and disengage the positioning block from the mounting plate. Then the mounting plate is unrestrained. By setting the auxiliary component, the mounting plate is effectively limited and fixed. This reduces the need for different mounting plates to support different types of circuit boards when the equipment is used. Existing mounting plates require bolts for installation, which requires tools and results in low installation efficiency. This auxiliary component, through the cooperation of the positioning block, connecting plate, sliding rod, and threaded rod, allows for quick replacement and fixing of the mounting plate, improving the stability of the equipment.

[0023] The specific settings and functions of its positioning device 6 and auxiliary components 7 will be discussed below.

[0024] In this embodiment: a positioning device 6 is provided on the upper surface of the placement plate 1. The positioning device 6 includes a mounting plate 61 and a circuit board 62. The mounting plate 61 is disposed on the upper surface of the placement plate 1, and the circuit board 62 is disposed above the mounting plate 61. A mounting groove 63 is formed on the upper surface of the mounting plate 61. A support block 64 is disposed inside the mounting groove 63. The support block 64 is disposed inside the circuit board 62. A pressure groove 65 is formed inside the support block 64.

[0025] Specifically, a limiting block 66 is provided inside the pressure groove 65, and one end of the limiting block 66 is engaged with the inside of the mounting groove 63.

[0026] In this embodiment: by setting the limiting block 66, the support block 64 can be limited, which reduces the possibility that the support block 64 may easily detach from the mounting plate 61 during use, making it difficult to fix the support block 64 inside the mounting plate 61.

[0027] Specifically, a pressure rod 68 is fixedly connected to the upper surface of the end of the limiting block 66 away from the limiting groove. The pressure rod 68 is slidably connected to the inside of the pressure groove 65. The pressure rod 68 is provided to facilitate the movement of the limiting block 66.

[0028] Specifically, a first spring 67 is fixedly connected to one end of the limiting block 66 near the pressure rod 68, and the other end of the first spring 67 away from the limiting block 66 is fixedly connected to the inside of the pressure groove 65. The first spring 67 is provided to facilitate the application of a reset spring force to the limiting block 66.

[0029] In this embodiment: An auxiliary component 7 is provided on the side of the placement plate 1 near the connecting arm 4. The auxiliary component 7 includes a positioning block 71 and a connecting plate 72. The positioning block 71 is located inside the mounting plate 61. The connecting plate 72 is fixedly connected to one end of the positioning block 71. A positioning plate 76 is fixedly connected to the side of the placement plate 1. A sliding rod 73 is fixedly connected inside the positioning plate 76. The sliding rod 73 is located inside the connecting plate 72. A threaded rod 74 is rotatably connected inside the positioning plate 76. The threaded rod 74 is rotatably connected inside the connecting plate 72. A nut 75 is fixedly connected to the surface of the connecting plate 72.

[0030] In this embodiment: by setting the positioning block 71, the mounting plate 61 can be fixed, reducing the difficulty of fixing the mounting plate 61 on the surface of the placement plate 1 when the equipment is in use.

[0031] Specifically, the threaded rod 74 is internally threaded to the nut 75, and a motor 77 is fixedly connected to one end of the threaded rod 74. The threaded rod 74 is provided to facilitate the movement of the connecting plate 72.

[0032] Specifically, a connecting seat 78 is fixedly connected to the surface of the motor 77. The connecting seat 78 is fixedly connected to the side of the placement plate 1. The connecting seat 78 is provided to facilitate the limiting of the motor 77.

[0033] Working principle: When the equipment is in use, the user presses the pressure rod 68. When the pressure rod 68 moves, it drives the limiting block 66 to move. When the limiting block 66 moves, it causes the first spring 67 to displace and deform, generating elastic force. Then, the limiting block 66 moves and disengages from the inside of the mounting groove 63. Subsequently, the support block 64 is unrestrained. By setting up the positioning device 6, the circuit board 62 is effectively positioned, which plays a supporting and positioning role for the circuit board 62. In general, the equipment has difficulty in positioning circuit boards 62 of different sizes and models, resulting in limitations in the processing of circuit boards 62. This positioning device 6, through the cooperation of components such as the mounting plate 61, the support block 64, the limiting block 66, and the first spring 67, can effectively position and support circuit boards 62 of different models, improving the stability of the equipment.

[0034] When the equipment is in use, the user starts the motor 77, which then rotates and drives the threaded rod 74 to move the nut 75. When the nut 75 moves, it drives the connecting plate 72 to move and disengage the positioning block 71 from the mounting plate 61. The mounting plate 61 then becomes unrestrained. The auxiliary component 7 effectively limits the mounting plate 61, thus fixing it in place. This reduces the need for different mounting plates 61 to support different types of circuit boards 62 during equipment processing. Existing mounting plates 61 require bolts for installation, which necessitates tools and leads to inefficient installation. This auxiliary component 7, through the interaction of the positioning block 71, connecting plate 72, sliding rod 73, and threaded rod 74, allows for quick replacement and fixing of the mounting plate 61, improving the equipment's stability.
