[0002] A printed circuit board (PCB) is a crucial electronic component that mounts electronic components onto a solid substrate and connects these components with copper and other materials to form a circuit. It is widely used in various electronic devices, such as computers, mobile phones, and home appliances.

[0003] In existing technologies, printed circuit boards (PCBs) require inspection during production. However, some inspection fixtures are fixed in size to fit within the PCB's diameter. Fixed fixtures cannot accommodate different types or sizes of PCBs, limiting the flexibility and adaptability of the production line. If the PCB design or dimensions change, the inspection fixture may need to be redesigned or replaced. Furthermore, the inspection process requires the PCB to be inspected at the optimal angle; the lack of an automatic angle adjustment mechanism in the fixture assembly can lead to uncertainties in the inspection data.

A spring 19 is provided on the inner wall of the clamping plate 110, and one end of the spring 19 is fixedly connected to the inner wall of the clamping plate 110. An L-rod 18 is provided on the other end of the spring 19, and one end of the L-rod 18 is fixedly connected to the other end of the L-rod 18. The other end of the L-rod 18 is fixedly connected to one side of the hollow ring 12. An inner column 111 is provided on the inner side of the hollow ring 12, and the outer side of the inner column 111 is fixedly connected to the inner side of the hollow ring 12. A driven gear 114 is provided on the outer side of the bottom end of the inner column 111, and the outer side of the bottom end of the inner column 111 is connected to the driven gear. The outer side of the driven gear 114 is engaged with the outer ring 114. The center end of the driven gear 114 is fixedly connected to one bottom end of the platform 11. A second motor 116 is provided at one bottom end of the platform 11, and one side of the second motor 116 is fixedly connected to the bottom end of the platform 11. A drive gear 115 is provided at the output end of the second motor 116, and the center end of the drive gear 115 is fixedly connected to the output end of the drive gear 116. The outer side of the drive gear 115 is engaged with the outer side of the driven gear 114. A fixed plate 15 is provided at one side end of the outer ring 13, and one side of the outer ring 13 is fixedly connected to one side of the fixed plate 15. A lead screw 16 is provided on the inner wall of the plate 15. The inner wall of the plate 15 is threadedly connected to the outer side of the lead screw 16. A motor 17 is provided at the bottom end of the lead screw 16. The bottom end of the lead screw 16 is fixedly connected to the output end of the motor 17. The bottom end of the motor 17 is fixedly connected to the inner side of the platform 11. A seat 112 is provided at the top of the inner column 111.

[0026] In this embodiment, when this type of tooling assembly for printed circuit board production is used, firstly, in order to be adaptable to printed circuit boards of different sizes, an outer ring 13 is installed on the outside of the empty ring 12. By starting the motor 17, the outer ring 13 begins to move upward under the rotation of the lead screw 16. During the upward movement, the pressing block 14 exerts external force on the four clamping plates 110, increasing the diameter space for inserting the printed circuit board. Subsequently, the printed circuit board is placed on the seat 112. At this time, the motor is reversed, and the pressing block 14 no longer exerts external force on the clamping plates 110. At the same time, the spring 19 resets the clamping plates 110, and during the reset process, the printed circuit board on the seat 112 is fixed. Therefore, this tooling can adapt to printed circuit boards of different sizes. This flexibility allows the screen printing machine to quickly switch between different specifications of circuit boards, which is beneficial to improving production efficiency and reducing the time for changing tooling.

[0027] Secondly, when inspecting printed circuit boards, the inspection equipment 113 needs to inspect the printed circuit boards at the optimal angle. Therefore, by starting the motor 116, the drive gear 115 drives the driven gear 114 to rotate. During the rotation of this gear, it will mesh with the inner column 111 to transmit power, thereby rotating the empty ring 12. Since the printed circuit board is fixed on the seat 112 at the top of the inner column 111, the printed circuit board will also be rotated and adjusted in the same way, so that the inspection equipment 113 can inspect it at the optimal angle, avoiding wear on the printed circuit board caused by manual adjustment and affecting subsequent use.

[0028] Example 2

[0029] As shown in Figure 5, the auxiliary mechanism 2 includes a base 21, a cylinder rod 22 is provided on the inner side of the base 21, the inner side of the base 21 is fixedly connected to the bottom end of the cylinder rod 22, the top end of the cylinder rod 22 is fixedly connected to the bottom side of the platform 11, and the inner wall of one bottom end of the platform 11 is slidably connected to one end of the base 21.

[0030] In this embodiment, a base 21 is installed on the bottom side of the platform 11. In order to make it suitable for operators of different heights, the base 21 will remain stationary when the cylinder rod 22 is retracted, and the bottom end of the platform 11 will move downward, thereby adjusting the overall height of the platform 11 to suit people of different heights. At the same time, since the position of the platform 11 is lowered, the insertion angle can be seen more intuitively when the printed circuit board is placed, and the body limbs can be coordinated more smoothly.
