Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to an automatic code reading device after laser engraving of components of a PCB circuit board. Background Art

[0002] Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can be called printed circuit boards or printed circuit boards. Circuit boards are divided into three major categories according to the number of layers: single-sided boards, double-sided boards, and multi-layer circuit boards.

[0003] The circuit board can be called a printed circuit board or a printed circuit board. It has the characteristics of high wiring density, light weight, thin thickness and good bending properties. When the existing code reading equipment is in operation, due to the presence of dust or impurities on the board, it will be blocked during subsequent scanning and reading. Therefore, we propose an automatic code reading device after laser engraving of PCB circuit board components to solve the above problems. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, a device for automatically reading codes after laser engraving of components on a PCB circuit board comprises an overall structure 1 and a supporting structure 2, wherein the supporting structure 2 is located at the front and rear positions on both sides of the bottom of the overall structure 1; the overall structure 1 comprises a bottom plate 101, a first electric slide 106 is fixedly installed at the front and rear positions of the top of the bottom plate 101, a connecting plate 107 is fixedly connected to the top of the first electric slide 106, a placement box 102 is fixedly connected at the top center of the connecting plate 107, second electric slides 116 are fixedly installed on the inner surfaces of both sides of the placement box 102 near the top position, soft brushes 115 are fixedly connected to the opposite sides of the two second electric slides 116, first telescopic rods 112 are fixedly installed at the bottom two sides of the placement box 102, a clamping plate 113 is fixedly connected to the protruding end of the first telescopic rod 112, and an insulating pad 114 is fixedly connected to the center of the inner surface of the clamping plate 113.

[0024] The effect achieved by the entire embodiment 1 is as follows: Figure 1 and Figure 3 As shown, when the second electric slide 116 is running, it will drive the soft-bristle brush 115 to move back and forth, so that the soft-bristle brush 115 can brush the surface of the circuit board back and forth to preliminarily remove the dust and impurities on the surface. Through the mutual cooperation of the first telescopic rod 112, the insulating pad 114 and the clamping plate 113, the circuit board can be limited to ensure that the circuit board can be stably placed in the placement box 102.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the outer surface of the clamping plate 113 is slidably connected to the inner surface of the placement box 102, the frame 105 is fixedly connected to the top rear side of the bottom plate 101, the second telescopic rods 104 are fixedly installed on both sides of the inner top of the frame 105, and a display screen 110 is fixedly installed on the inner surface of the rear side of the frame 105 near the top, one of the second telescopic rods 104 is fixedly connected to the laser engraving machine 103 at the extended end, and the other second telescopic rod 104 is fixedly connected to the extended end of the two-dimensional code scanner 108, and a gas injector 111 is fixedly installed on the other side of the top of the frame 105, and the gas outlet pipe of the gas injector 111 is penetrated by a conveying pipe 109, and the supporting structure 2 includes a connecting rod 201, and the bottom end surface of the connecting rod 201 is fixedly connected to the anti-slip pad 202, and the top end surface of the connecting rod 201 is fixedly connected to the bottom surface of the bottom plate 101.

[0026] The effect achieved by the entire embodiment 2 is as follows: Figure 1 and Figure 4 As shown, when the second telescopic rod 104 is extended or retracted, it will drive the laser engraving machine 103 or the two-dimensional code scanner 108 to move up and down, so that the two can operate normally on the circuit board later. By setting the connecting rod 201 and the anti-skid pad 202, the stability of the whole when it is in use can be improved, and the cooperation of the anti-skid pad 202 can increase the friction between the ground, ensuring that the whole will not be displaced when in use.

[0027] Working principle: First, the user puts the circuit board into the placement box 102. After putting it in, the first telescopic rod 112, the clamping plate 113 and the insulating pad 114 cooperate with each other to clamp the circuit board to avoid displacement during subsequent movement. After fixing, the second electric slide 116 runs to drive the soft brush 115 to move back and forth, so that the soft brush 115 can brush the surface of the circuit board back and forth to preliminarily remove dust and impurities on the surface. After the preliminary cleaning, the second telescopic rod 104 on one side extends to drive the laser engraving machine 103 to descend. After descending to a certain position, the circuit board can be cleaned. After coding processing, the first electric slide 106 runs to drive the placement box 102 to move to the other side. After moving to the position corresponding to the two-dimensional code scanner 108, the gas injector 111 runs, and the generated airflow can be transported through the conveying pipe 109, and finally blown onto the circuit board to remove dust and impurities on the surface, ensuring that the subsequent two-dimensional code scanner 108 can scan normally. After the second cleaning, the second telescopic rod 104 on the other side is extended to drive the two-dimensional code scanner 108 to descend. After descending to the appropriate position, it can be scanned, and the user can view the read data through the display screen 110.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
