Description

Technical Field

[0001] This utility model relates to the field of long strip sheet material inspection technology, specifically a sheet material defect marking device. Background Technology

[0002] The sheet materials are transported on an assembly line during production, and a defect detection device is installed on the assembly line. After a defective sheet material is detected, the defective part needs to be cut off. The remaining qualified part of the sheet material can be cut shorter and made into finished products. However, some assembly lines do not have a marking device. Therefore, the defective sheet material detected needs to have its defect location determined again before it is cut off, which wastes time.

[0003] Therefore, there is a need for a device that can be installed on existing sheet production lines and automatically mark defects in sheet parts according to instructions during the production process. Utility Model Content

[0004] The purpose of this invention is to provide a sheet material defect marking device that can be installed independently of existing production lines and can automatically mark defects according to instructions from the defect detection device on the production line.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sheet material defect marking device, used in conjunction with a sheet material conveyor belt, includes a fixed frame, a sheet material guide wheel, a sheet material bottom support wheel, a cylinder frame, a marking cylinder, and a color mark sensor. The fixed frame is located at the rear end of the sheet material conveyor belt, and a marking platform is provided on the top of the fixed frame. The sheet material guide wheel is located at the front end of the marking platform, and the sheet material bottom support wheel is located in the middle of the marking platform. The sheet material passes through the top of the sheet material guide wheel and the sheet material bottom support wheel. The marking cylinder is fixed on the cylinder frame and positioned diagonally above the sheet material bottom support wheel. The color mark sensor is located above the position where the sheet material passes through. The marking cylinder and the color mark sensor are connected to a controller of the sheet material conveyor belt device.

[0007] In this solution, the sheet material defect marking device is installed at the exit end of the sheet material conveyor belt device. This eliminates the need to add equipment to the original production line, reducing the difficulty of modification and avoiding production stoppage. After exiting the exit, the sheet material is guided to the sheet material defect marking device by the sheet material guide wheel and supported by the bottom support roller. The marking cylinder obtains the location of the defect from the defect detection device on the production line and marks the location according to the instruction. The telescopic rod of the marking cylinder is equipped with a replaceable marker. After marking, the sheet material continues to pass through the color mark sensor, which determines whether a color mark has been applied. After marking and verification, the defective section of the sheet material can be easily removed at the marked location.

[0008] In a preferred embodiment of this invention, the marking platform is connected to the top of the fixed frame via multiple lifting screws and tightening nuts. The distance between the marking platform and the top of the fixed frame can be adjusted by the position of the tightening nuts, effectively adjusting the vertical height of the marking platform to align with the outlet of the production line.

[0009] In a preferred embodiment of this invention, the sheet guide wheel includes a guide frame, a connecting plate, and a guide pressure roller. The guide frame is connected to the marking platform, the connecting plate is bolted to the guide frame, and the guide pressure roller is rotatably connected to the connecting plate. The relative height of the guide pressure roller in this embodiment can be achieved through the rotation and fixing of the connecting plate and the guide frame.

[0010] As a preferred embodiment of this utility model, the sheet bottom support roller includes a bracket and a support roller. The bracket is connected to the marking platform, and the support roller is rotatably connected to the bracket. In this embodiment, the sheet bottom support roller is used to support the sheet material and to hold the sheet material in place when the marking cylinder is operating.

[0011] As a preferred embodiment of this utility model, the cylinder frame includes an upper and lower movable frame, a movable guide rail, and an adjusting bolt. The marking cylinder is equipped with a high-speed solenoid valve and a pneumatic triplet. The marking cylinder and the high-speed solenoid valve are fixed on the upper and lower movable frame. The upper and lower movable frame and the movable guide rail are movably connected. The adjusting bolt is rotatably connected to the movable guide rail and threadedly connected to the upper and lower movable frame. The pneumatic triplet is fixed on a fixed frame. The marking cylinder of this embodiment uses a finger-operated cylinder and achieves high-frequency marking action through a high-speed solenoid valve. The position of the marking cylinder can also be adjusted up and down by the upper and lower movable frame and the movable guide rail. The upper and lower movable frame and the movable guide rail are linearly movable with limit. The adjusting bolt does not displace when rotating relative to the movable guide rail, while the upper and lower movable frame, which is threadedly connected to the adjusting bolt, moves up and down along the movable guide rail, similar to the lifting function of a lead screw and lead screw nut. The pneumatic triplet is connected to the marking cylinder and the pressure air source respectively.

[0012] As a preferred embodiment of this utility model, the color mark sensor includes a sensor frame, which is fixed on the marking platform. The color mark sensor is located diagonally above the bottom support roller of the sheet. The color mark sensor in this embodiment is an existing device capable of distinguishing colors. It determines whether marking has been completed on the sheet and uploads the information. The color mark sensor and the marking cylinder are located diagonally above the bottom support roller on both sides of the sheet, and the sheet passes sequentially through the marking cylinder and the color mark sensor.

[0013] As a preferred embodiment of this utility model, the fixing frame includes an upper fixing sleeve, a profile with bolt fixing grooves, and a lower fixing sleeve. The upper and lower fixing sleeves are respectively fixed to both ends of the profile with bolt fixing grooves, and the marking platform is bolted to the upper fixing sleeve. This fixing frame is made from readily available materials and is simple to manufacture. The profile with bolt fixing grooves facilitates the mounting of other devices.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention can be installed independently of existing production lines. Based on the instructions of the defect detection device on the production line, it can automatically mark and judge the marking results. Attached Figure Description
