Description

Technical Field

[0001] This utility model relates to the technology of circuit board production and testing, and in particular to a CCD automatic detection and identification device. Background Technology

[0002] A CCD inspection instrument is an instrument that uses a CCD camera to inspect the appearance of an object through a display. It is highly versatile, and different inspection fixtures can be used to inspect products of different part numbers. Furthermore, it allows direct observation of the image on the display with the naked eye. Compared to projectors and microscopes, it reduces operator fatigue, is easy to use, and increases the efficiency of product inspection.

[0003] However, when CCD inspectors are inspecting circuit boards in transit, because there are many components on the circuit boards, if the CCD inspector is installed above the conveyor line, the CCD inspector may not be able to accurately detect whether there is a shortage of material on the circuit board due to the fast movement speed of the circuit board. For this reason, some circuit board manufacturers will manually pick up the circuit boards from the conveyor line and put them on the processing table for inspection by the CCD inspector. During the inspection process, the position of the circuit board needs to be manually adjusted to align with the CCD inspector, which increases the inspection time of the circuit board and reduces production efficiency. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide an automatic CCD detection and recognition device to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a CCD automatic detection and identification device for detecting circuit boards on a conveyor platform. The conveyor platform includes an adjacent conveyor line and a processing table. The top of the processing table is provided with a limiting support component and a camera component. The camera component is adjustable and located on top of the limiting support component and is connected to a display screen suspended in the air. The limiting support component includes at least one limiting block and a soft pad. The upper end of the soft pad is provided with a receiving groove for accommodating the circuit board.

[0006] During testing, take the circuit board from the conveyor line and place it on the receiving slot, aligning the camera end of the camera assembly with the circuit board so that the display screen shows the status of the components on the circuit board.

[0007] Furthermore, the lower part of one side of the limiting block is provided with a notch for inserting a soft pad, and a pressing element is provided inside the notch.

[0008] Furthermore, the extrusion component is a screw, and the extrusion component extends into the recess at the top of the limiting block.

[0009] Furthermore, the inner cavity of the limiting block is provided with a cavity that communicates with the notch, the side wall of the extruder is adapted to the inner wall of the cavity, and a limiting element connected to the extruder is provided in the cavity.

[0010] Furthermore, the limiting component is a spring, and the two ends of the spring are connected to the top wall of the cavity and the top of the extruder, respectively.

[0011] Furthermore, the side wall of the limiting block is provided with an insertion port that communicates with the cavity, and the limiting component is an insertion plate, which is inserted into the insertion port.

[0012] Furthermore, the camera assembly includes a camera and an adjustment bracket, with the camera located at the top of the receiving slot and the adjustment bracket connected to the camera.

[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, by cooperating with the conveyor line and the processing table, and with the limiting bearing component and the camera component set on the processing table, the operator can pick up the circuit board on the conveyor line and place it on the bearing component on the processing table for the camera component to detect. After the detection is completed, the operator picks up the circuit board on the bearing component of the limiting bearing component and places it back on the conveyor line for transmission, thereby increasing the detection efficiency and accuracy of the circuit board.

[0024] Please refer to Figure 1-4As shown, it illustrates the specific structure of a preferred first embodiment of the present invention, which is a CCD automatic detection and identification device used to detect circuit boards 2 on a conveyor platform 1. The conveyor platform 1 includes an adjacent conveyor line 11 and a processing table 12. The top of the processing table 12 is provided with a limiting support component 20 and a camera component 30. The camera component 30 is adjustable and located on top of the limiting support component 20, and is connected to a display screen 3 suspended in the air. The limiting support component 20 includes at least one limiting block 21 and a soft pad 22. The upper end of the soft pad 22 is provided with a receiving groove 23 for accommodating the circuit board 2.

[0025] During inspection, circuit board 2 is taken from conveyor line 11 and placed on receiving slot 23, aligning the camera end of camera component 30 with circuit board 2 so that display screen 3 shows the status of parts on circuit board 2. Compared to existing CCD automatic inspection and recognition equipment, which places the circuit board on top of a conveyor line (due to its high speed and the large number of components to be inspected on the circuit board, resulting in insufficient inspection accuracy), or placing the circuit board on a processing platform (which is an independent platform not integrated with the conveyor line, increasing the processing steps), this CCD automatic inspection and recognition equipment, through the cooperation of conveyor line 11 and processing table 12, with limiting support component 20 and camera component 30 located on processing table 12, allows the operator to take circuit board 2 from conveyor line 11 onto support component 20 on processing table 12 for inspection by camera component 30. After inspection, the operator removes circuit board 2 from support component 20 and places it back on conveyor line 11 for transmission, thereby increasing the inspection efficiency and accuracy of circuit board 2.

[0026] Specifically, a soft pad 22 is placed on the upper surface of the processing table 12. To prevent the soft pad 22 from moving arbitrarily and causing the circuit board 2 and the camera assembly 30 placed on it to become misaligned, a limiting block 21 is fixed on the processing table 12. The movement of the soft pad 22 is restricted by the connection between the limiting block 21 and the soft pad 22. After the operator picks up the circuit board 2 conveyed on the conveyor line 11 and places it in the receiving slot 23, the circuit board 2 corresponds to the camera end of the camera assembly 30, thereby enhancing the accuracy and speed of the detection of the circuit board 2.

[0027] Specifically, the lower part of one side of the limiting block 21 is provided with a recess 211 for inserting the soft pad 22, and an extrusion member 212 is provided in the recess 211. The recess 211 is opened at the fixed end of the limiting block 21 and the processing table 12, so that the soft pad 22 laid on the processing table 12 can be inserted into the recess 211, and the soft pad 22 is limited by the extrusion member 212 in the recess 211.

[0028] In one embodiment, the pressing member 212 is a screw, and the pressing member 212 extends into the recess 211 at the top of the limiting block 21. The limiting block 21 is provided with a threaded opening that communicates with the recess 211. When limiting the soft pad 22 in the recess 211, the screw is turned downward along the threaded opening and the soft pad 22 is pressed, thereby limiting the soft pad 22.

[0029] In another embodiment, the inner cavity of the limiting block 21 is provided with a cavity 213 communicating with the recess 211, the side wall of the extruder 212 is adapted to the inner wall of the cavity 213, and the cavity 213 is provided with a limiting member 214 connected to the extruder 212.

[0030] It should be noted that the limiting member 214 is a spring, and the two ends of the spring are connected to the top wall of the cavity 213 and the top of the extruder 212, respectively. When the limiting member 214 is a spring, the user can push the extruder 212 into the cavity 213 by inserting a finger into the recess 211, then push the soft pad 22 into the recess 211, and release the extruder 212. Under the elastic reset, the spring pushes the extruder 212 to squeeze the soft pad 22 in the recess 211, thereby limiting the soft pad 22.

[0031] It should be noted that the side wall of the limiting block 21 is provided with an insertion port 215 communicating with the cavity 213, and the limiting member 214 is an insertion plate, which is inserted into the insertion port 215. When the limiting member 214 is an insertion plate, when the soft pad 22 is pushed into the recess 211, the insertion plate is pushed through the insertion port 215 according to the thickness of the soft pad 22 to limit the extrusion member 212, so that the soft pad 22 located below the extrusion member 212 is effectively limited.

[0032] The camera assembly 30 includes a camera 31 and an adjustment bracket 32. The camera 31 is located on top of the receiving slot 23, and the adjustment bracket 32 ​​is connected to the camera 31.

[0033] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
