Description

Technical Field

[0001] The utility model relates to the technical field of multi-layer rigid-flexible circuit boards, in particular to a character spray printing device for a multi-layer rigid-flexible circuit board. Background Art

[0002] Multilayer rigid-flexible circuit board is a type of composite circuit board commonly used in electronic devices. It combines the characteristics of rigid and flexible circuit boards and has good mechanical strength and flexible connectivity. This type of circuit board is usually composed of multiple layers of rigid substrate and flexible copper foil, which are combined together through a specific processing technology.

[0003] For example, a circuit board printing device disclosed in publication number CN210415912U has the following beneficial effects: the circuit board printing device is provided with an x-axis adjustment mechanism and a Y-axis adjustment mechanism on the clamping table, and the x-axis adjustment mechanism and the Y-axis adjustment mechanism cooperate with each other to clamp circuit boards of different specifications, thereby improving adaptability. At the same time, the x-axis adjustment mechanism and the Y-axis adjustment mechanism respectively clamp the edges of the circuit board, which can effectively fix the circuit board, prevent it from moving during the printing process, and reduce the printing quality. However, in the above-mentioned patent, when it is necessary to print the back side of the circuit board, the usual practice is to remove the circuit board from the printing table after one side of the printing is completed, turn it over manually, and then place it on the printing table again for back side printing. This turning process not only increases the complexity of the operation, but also significantly reduces the overall efficiency of the printing; secondly, after each printing of a circuit board is completed, the equipment needs to pause so that the operator can remove the printed circuit board from the equipment and replace it with a new circuit board to be printed. During this process, the equipment is idle, which not only wastes production time, but also may lead to a decrease in equipment utilization, thereby increasing production costs.

[0004] Therefore, there is an urgent need for a multi-layer rigid-flexible circuit board character printing device to solve the above problems. Utility Model Content

[0026] A positioning assembly 4 is disposed on the top of the connecting rod 311 .

[0027] Specifically, the positioning assembly 4 includes a concave box 41 fixedly connected to the connecting rod 311, the inner cavity of the concave box 41 is slidably connected to a clamping plate 42, one side of the clamping plate 42 is fixedly connected to a plurality of springs 43, one end of the spring 43 is fixedly connected to the concave box 41, one side of the clamping plate 42 is fixedly connected to a connecting rod 44, one end of the connecting rod 44 passes through the outside of the concave box 41.

[0028] In this embodiment: through the setting of the positioning component 4, by pulling the connecting rod 44, the connecting rod 44 drives the clamping plate 42 to move to one side and squeezes the spring 43. At this time, the multi-layer rigid-flexible circuit board is placed in the inner cavity of the concave box 41, and the force pulling the connecting rod 44 is released. Under the elastic potential energy of the spring 43, the clamping plate 42 is driven to move close to one side of the multi-layer rigid-flexible circuit board, thereby realizing the positioning of the multi-layer rigid-flexible circuit board.

[0029] Specifically, two slide grooves 45 are provided at the bottom of the inner cavity of the concave box 41 , and one side of the clamping plate 42 extends to the inner cavity of the slide groove 45 and is slidably connected to the slide groove 45 .

[0034] In this embodiment, through the coordinated use of the stabilizing groove 6 and the stabilizing block 7 , the rotating plate 35 will drive the stabilizing block 7 to slide in the inner cavity of the stabilizing groove 6 when rotating, thereby playing a role in providing stable support for the rotating plate 35 .

[0035] The working principle and use process of the utility model are as follows: when in use, the linkage rod 44 is pulled, and the linkage rod 44 drives the clamping plate 42 to move to one side and squeeze the spring 43. At this time, the multi-layer rigid-flexible circuit board is placed in the inner cavity of the concave box 41, and the force pulling the linkage rod 44 is released. Under the elastic potential energy of the spring 43, the clamping plate 42 is driven to move close to one side of the multi-layer rigid-flexible circuit board, thereby realizing the positioning of the multi-layer rigid-flexible circuit board, and further using the printing device 2 located on the left side to print the multi-layer rigid-flexible circuit board. When the multi-layer rigid-flexible circuit board is positioned After one side of the rigid-flexible circuit board is completed, the motor 31 is started, and the output shaft of the motor 31 drives the driving gear 32 to rotate. When the driving gear 32 rotates, it drives the driven gear 37 to rotate. The driven gear 37 drives the rotating plate 35 to rotate through the transmission of the circular sleeve 36. Since the fixed gear 34 is in a fixed state under the connection of the fixed rod 33, the fixed gear 34 will not rotate when the rotating plate 35 rotates. When the rotating plate 35 rotates, it rotates with the fixed rod 33 as the axis point, and the rotating plate 35 drives the movable gear 39 to rotate around the fixed gear 34 rotates, and the movable gear 39 rotates around the fixed gear 34 and rotates at the same time. When the movable gear 39 rotates, it drives the driving pulley 38 to rotate in the same direction. The driving pulley 38 drives the driven pulley 310 to rotate through the transmission connection of the belt. The driven pulley 310 drives the positioning assembly 4 to rotate through the transmission of the connecting rod 311. The movable gear 39 moves from the left side of the fixed gear 34 to the right side of the fixed gear 34, and needs to rotate 180 degrees, so the driving pulley 38 drives the driven pulley 310 to rotate 180 degrees, and the driven pulley 310 can drive the multi-layer rigid-flexible circuit board to rotate 180 degrees through the transmission of the connecting rod 311 and the positioning component 4. At this time, the printing device 2 located on the right is used to print the back of the multi-layer rigid-flexible circuit board. When the back of the multi-layer rigid-flexible circuit board is printed, it moves to the front side of the fixed gear 34. At this time, the worker removes the multi-layer rigid-flexible circuit board after printing and replaces it with a multi-layer rigid-flexible circuit board that has not been printed, which can reduce the idle time of the equipment and improve the efficiency of the entire printing process.
