Abstract
Description
Technical Field
[0001] This application relates to the field of circuit board component insertion technology, and in particular to a circuit board flipping fixture. Background Technology
[0002] Circuit boards, also known as printed circuit boards, make circuits miniaturized and more intuitive. They play a crucial role in the mass production of fixed circuits and the optimization of electrical appliance layouts, thus finding widespread application in various electrical appliances and smart tools. When inserting or mounting components onto circuit boards, workers need to use fixed flip-mount components to flip the boards and adjust their orientation.
[0003] However, the current fixed flip-over components still have some shortcomings. If the bottom of the circuit board is not supported when performing some plug-in or surface mount processes, the circuit board may bend or other problems may occur. Utility Model Content
[0004] To address the shortcomings of the prior art, this application provides a circuit board flipping fixture with a simple structure, strong practicality, and the ability to effectively improve processing efficiency.
[0005] To achieve the above objectives, the present invention employs the following technology: A circuit board flipping fixture includes a rectangular frame with a first clamping frame on one side. A second clamping frame, parallel to the first clamping frame, is movably mounted inside the rectangular frame. The first and second clamping frames have openings facing the rectangular frame, with the opening ends facing each other. The first clamping frame has two symmetrical through slots along its width on the side away from the rectangular frame. The through slots are used to allow two first clamping layers, which are symmetrically arranged vertically and move through the first clamping frame, to pass through. The width of the first clamping layer is greater than a predetermined maximum distance between the first and second clamping frames. The top and bottom surfaces of the second clamping frame are fitted with second clamping layers corresponding to the first clamping layers. One end of the rectangular frame is rotatably connected to a vertically mounted mounting plate, and the axis of rotation of the rectangular frame is perpendicular to the plane of the mounting plate.
[0006] The advantages of this utility model are as follows: the arrangement of the first clamping frame and the second clamping frame can fix circuit boards of different lengths or widths; the rotation of the rectangular frame can realize the flipping of the circuit board; the movable arrangement of the first clamping layer can selectively provide support for the bottom of the circuit board according to the different processing tasks; the structure is simple, the practicality is strong, and it can effectively improve the processing efficiency.

[0012] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.
[0013] This application provides a circuit board flipping fixture, such as... Figures 1-4 As shown, the device includes a rectangular frame 1, with a first clamping frame 11 on one side. A second clamping frame 12, parallel to the first clamping frame 11, is movably disposed within the rectangular frame 1. Both the first clamping frame 11 and the second clamping frame 12 have openings facing the rectangular frame 1, with their opening ends opposite each other. Two symmetrical vertical slots 111 extend through the side of the first clamping frame 11 away from the rectangular frame 1, allowing two symmetrically arranged first clamping layers 112 to pass through. The width of each first clamping layer 112 is greater than the width of the first clamping frame 11 and the second clamping frame 12. The predetermined maximum distance of the holding frame 12, the top and bottom surfaces of the second clamping frame 12 are corresponding to the first clamping layer 112 and the second clamping layer 121 is installed. The reason why the two through slots 111 are not designed as one piece is that a blocking part will be formed in the middle of the side of the first clamping frame 11 away from the rectangular frame 1, so as to prevent the circuit board from being taken out when the first clamping layer 112 is moved out of the rectangular frame 1. One end of the rectangular frame 1 is rotatably connected to a vertically set mounting plate 2, and the rotation axis of the rectangular frame 1 is set perpendicular to the plane of the mounting plate 2. In order to improve the stability of the rotation of the rectangular frame 1, the other end of the rectangular frame 1 is rotatably connected to a vertical plate.
[0014] In application, the first clamping frame 11 is used to fix one side of the circuit board. The second clamping frame 12 is moved according to the width of the circuit board to adjust the distance between the first clamping frame 11 and the second clamping frame 12. Then, the second clamping frame 12 is used to fix the other side of the circuit board. The circuit board can be flipped by rotating the rectangular frame 1 180 degrees. When the circuit board is in a horizontal state and support is needed for the bottom of the circuit board, the first clamping layer 112 located below can be moved.
[0015] Specifically, such as Figures 1-4 As shown, the first clamping layer 112 includes a first substrate layer slidably fitted to the top or bottom surface inside the first clamping frame 11, and a first inflatable layer mounted inside the first substrate layer. The second clamping layer 121 includes a second substrate layer mounted to the top or bottom surface inside the second clamping frame 12, and a second inflatable layer mounted inside the second substrate layer. The sliding fit between the first substrate layer and the top or bottom surface inside the first clamping frame 11, and the sliding fit between the second substrate layer and the top or bottom surface inside the second clamping frame 12, can both be achieved through a T-slot and a T-rail sliding fit. The first and second inflatable layers allow for adjustment of the distance between the first clamping layer 112 and the second clamping layer 121 to accommodate circuit boards of different thicknesses. They also provide cushioning for the circuit board, preventing damage during fixing. Because the widths of the first and second inflatable layers are different, the amount of air required to achieve the same thickness is also different; therefore, the first and second inflatable layers need to be inflated separately. More specifically, pressure plates with a high coefficient of friction can be installed on the inner sides of the first and second inflatable layers to improve the fixing effect of the first clamping frame 11 and the second clamping frame 12.
[0016] Specifically, such as Figures 1-4 As shown, the first clamping frame 11 has two symmetrically arranged round rods 15 connected along its width direction on the side away from the rectangular frame 1, and the round rods 15 are located on the outside of the first clamping layer 112. The first clamping layer 112 has a column formed on the side away from the rectangular frame 1, and the column slides through the round rods 15. The round rods 15 are fitted with springs 16, and the springs 16 are located between the first clamping frames 11. When the springs 16 are in their natural state, the side of the first clamping layer 112 facing the rectangular frame 1 is flush with the side of the first clamping frame 11 facing the rectangular frame 1. The purpose of the springs 16 is to allow the first clamping layer 112 to automatically reset when no external force is applied to it. The mounting plate 2 has push plates 21 that move along its length direction at both ends. When the rectangular frame 1 is in a horizontal state, the push plates 21 are at the same height as the through slot 111 located below. The push plates 21 are used to push the first clamping layer 112 located below to support the bottom of the circuit board.
[0017] Specifically, such as Figure 1 As shown, both ends of the mounting plate 2 are rotatably mounted with first screws 22 along its length. A push plate 21 is threaded through one of the first screws 22. The first screws 22 can be driven by manual rotation.
[0018] Specifically, such as Figure 1 and Figure 3As shown, guide rods 13 and second screws 14 are respectively installed at both ends of the rectangular frame 1 along its width direction. One end of the second clamping frame 12 is slidably inserted through the guide rod 13, and the other end is threaded through the second screw 14. The second screw 14 is driven to rotate by a first motor to realize the movement of the second clamping frame 12.
[0019] Specifically, such as Figure 1 and Figure 2 As shown, a first gear 3 is sleeved on the shaft of the rectangular frame 1 near the mounting plate 2. The first gear 3 meshes with a second gear 4. The second gear 4 is rotatably mounted on the mounting plate 2 and driven to rotate by a second motor.
[0020] In application, the above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
