Description

Technical Field

[0001] This invention relates to the technical field of SMT placement equipment, and in particular to an optical character recognition mechanism on a feeder. Background Technology

[0002] In traditional SMT production, manual loading of feeders onto placement machines is often required based on production orders and Bill of Materials (BOMs). This involves manually verifying that the model, specifications, polarity, and other characteristics of the components being loaded match the program requirements. A single circuit board typically contains a large number of different components, necessitating a large number of feeders of varying sizes and arrangements. Manual operation is susceptible to human error, particularly when handling large volumes, due to factors such as operator skill level, fatigue, and subjective judgment. Errors in feeder loading can result in the loss of hundreds of circuit boards, production line downtime, and increased costs. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing an optical character recognition mechanism for feeders, which offers high positioning accuracy and significantly improves adjustment efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts an optical character recognition mechanism on a feeder, comprising: a frame, a linear drive mechanism mounted on the frame, a first button mechanism, a second button mechanism, a third button mechanism mounted on the linear drive mechanism, a vision inspection mechanism mounted on the frame, and an image acquisition mechanism. The vision inspection mechanism and the image acquisition mechanism are used to collect parameter information of the feeder on the transmission track. The linear drive mechanism is used to drive the first button mechanism, the second button mechanism, and the third button mechanism to move to the required position. The first button mechanism, the second button mechanism, and the third button mechanism can perform downward or upward movements to replace manual control buttons and realize the forward and backward movement of control components and the loosening and tightening of the conveyor belt.

[0006] In a preferred embodiment of the present invention, the parameter information of the feeder includes the feeder's characters, images, lights, position, and the polarity information of the components.

[0010] In a preferred embodiment of the present invention, the linear drive mechanism includes a linear module and a translation plate disposed on the linear module.

[0011] In a preferred embodiment of the present invention, the first button mechanism, the second button mechanism and the third button mechanism have the same structure, including: a top plate disposed on the translation plate, a second pressing cylinder disposed on the top plate and a pressing member disposed on the output end of the second pressing cylinder.

[0012] In a preferred embodiment of the present invention, a safety cover is further provided on the periphery of the frame.

[0013] In a preferred embodiment of the present invention, the safety housing is provided with a warning light and a display screen.

[0014] The beneficial effects of this invention are: by replacing manual inspection of component polarity and position with a visual inspection mechanism, and by replacing manual control of buttons with a three-button mechanism to control the forward and backward movement of components, the loosening and tightening of the conveyor belt, and the automated identification and operation, the demand for human resources is reduced and the cost of manual operation is lowered.

[0020] Please see Figure 1-3 This invention discloses an optical character recognition mechanism for a feeder, comprising a frame 1, a linear drive mechanism 2 mounted on the frame, a first button mechanism 3, a second button mechanism 4, a third button mechanism 5 mounted on the linear drive mechanism, a vision inspection mechanism 6 mounted on the frame, and an image acquisition mechanism 7. The vision inspection mechanism and the image acquisition mechanism are used to monitor the parameter information of the feeder on the transmission track. The feeder parameter information includes the characters, images, lights, position, and polarity information of the components. The linear drive mechanism is used to drive the first button mechanism, the second button mechanism, and the third button mechanism to move to the desired position. The first button mechanism, the second button mechanism, and the third button mechanism can perform downward or upward movements to replace manual control buttons and control the forward and backward movement of the components, as well as the loosening and tightening of the conveyor belt.

The circuit board often has a large number of different components. The system obtains information and makes visual judgments to accurately move to the required position. The three sets of button mechanisms can replace manual control of the buttons to control the forward and backward movement of the components, as well as the loosening and tightening of the conveyor belt, reducing the demand for human resources and lowering the cost of manual operation.

[0022] Specifically, this application also includes a control system, wherein the first button mechanism, the second button mechanism, the third button mechanism, the vision inspection mechanism, and the image acquisition mechanism are connected to the control system signal. This control system is existing technology and typically includes sensors, computers, programmable controllers, and algorithms to monitor and control the operation of the entire mechanism, obtain work order parameters of the production system to automatically adjust the vision inspection mechanism and multiple sets of button mechanism modules, and trigger the vision inspection mechanism and the image acquisition mechanism to capture images at appropriate times, and perform actions such as pressing down and lifting the three sets of buttons. The control system can also analyze image data in real time to detect and identify possible anomalies.

[0023] Specifically, the visual inspection mechanism includes a vertical plate 61, a connecting plate 62 mounted on the vertical plate, a first pressing cylinder 63 mounted on the connecting plate, a position sensor 64, and a CCD camera 65 mounted on the input end of the first pressing cylinder.

It can clearly acquire characters, images, lights, positions, and the polarity and position of components on the feeder.

[0024] It also includes a safety enclosure 8 located around the machine frame, which is equipped with a warning light 81 and a display screen 82.

[0025] The beneficial effects of this invention are: This application uses a visual inspection mechanism to replace manual inspection of component polarity and component position, and uses a three-set button mechanism to replace manual control of buttons to control the forward and backward movement of components, the loosening and tightening of the conveyor belt, and automated identification and operation, reducing the demand for human resources and lowering the cost of manual operation.
