Description

Technical Field

[0001] This utility model relates to the field of sorting device technology, and in particular to a sorting device for detecting defects in FPC steel sheets. Background Technology

[0002] FPC steel sheets are primarily used to enhance the structural strength of flexible printed circuit boards (FPCs), especially in applications requiring improved soldering quality, prevention of deformation, and extended lifespan. In communication electronic equipment, FPC steel sheets are used to strengthen the stability of the circuit board, ensuring the continuity and reliability of signal transmission.

[0003] After FPC steel sheets are produced, defective products need to be removed through inspection and sorting devices. Current inspection and sorting devices mainly place the FPC steel sheets on a conveyor, take pictures using industrial cameras on the conveyor, and feed the image information back to a vision controller. The vision controller analyzes the information and feeds it back to a PLC, which then controls a robotic arm or sorting mechanism to remove the defective FPC steel sheets. The above describes current inspection and sorting devices. These devices are often integrated into the conveyor mechanism, making them difficult to disassemble and limiting their application. Each conveyor requires a separate sorting device. Furthermore, traditional robotic arms, which pick up and place the sheets, are not efficient enough at grasping thin FPC steel sheets. Therefore, we have designed a sorting device for detecting defects in FPC steel sheets. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sorting device for detecting defects in FPC steel sheets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sorting device for detecting defects in FPC steel sheets includes a screening channel, a guide channel rotatably connected to the top side of the screening channel, a dividing plate fixed to the bottom middle of the screening channel, and a sorting mechanism installed on the screening channel near the guide channel.

[0007] The sorting mechanism includes a mounting frame, which is an L-shaped structure. Rollers are evenly rotatably mounted on the bottom of the mounting frame. A connecting rod is fixed to the bottom of the mounting frame near the material guide channel. A hole is opened on the screening channel for the connecting rod to pass through. A swing mechanism for rotating the connecting rod is installed at the bottom of the screening channel.

[0008] As a further solution of the utility model, the swing mechanism includes a first synchronous pulley driven by a bidirectional motor. The first synchronous pulley is connected to a second synchronous pulley through a synchronous belt, and the second synchronous pulley is coaxially fixed with a connecting rod.

[0009] As a further solution of the utility model, a motor bracket is fixed at the bottom of the screening channel. The bidirectional motor is fixed at the bottom of the motor bracket, and the output shaft of the bidirectional motor is coaxially fixed with the first synchronous pulley.

[0010] As a further solution of the utility model, a side block is fixed at the bottom of one end of the top of the screening channel far from the side guard plate. When the mounting bracket deflects corresponding to the dividing plate, it fits with the dividing plate.

[0011] As a further solution of the utility model, a second electric telescopic rod is rotatably connected to the bottom of the screening channel. The output end of the second electric telescopic rod is rotatably connected to the bottom of the material guiding channel. The material guiding channel and the second electric telescopic rod are provided, and the inclination degree of the material guiding channel can be adjusted through the second electric telescopic rod, which is convenient for adjusting the sliding of the FPC steel sheet.

[0012] As a further solution of the utility model, a support mechanism is installed below the screening channel. The support mechanism includes a mounting table. First electric telescopic rods are fixed at the four corners of the bottom of the mounting table. At both ends of one side of the top of the mounting table far from the dividing plate, support rods are fixed. The height of the screening channel and the material guiding channel can be adjusted integrally through the work of the first electric telescopic rods to meet the installation of the detection and conveying equipment. The top of the support rod is fixed to the bottom of the screening channel, and both ends of one side of the top of the mounting table far from the support rod are fixed to the bottom of the screening channel through fixing blocks.

[0013] As a further solution of the utility model, a PLC controller is installed on the top of the mounting table. The PLC controller is electrically connected to the bidirectional motor.

[0014] The beneficial effects of the utility model are as follows:

[0015] For the utility model: due to the adoption of the arranged screening channel, side guard plate, dividing plate, side block, sorting mechanism, material guiding channel and swing mechanism, when the industrial camera detects that the FPC steel sheet is unqualified, the vision controller feeds back the detection result to the PLC controller. The PLC controller controls the bidirectional motor to work. The first synchronous pulley rotates the second synchronous pulley through the synchronous belt, and then the swing of the mounting bracket is realized. The mounting bracket swings to the position of the side block, so that the unqualified FPC steel sheet slides off. When the FPC steel sheet is detected to be qualified, the mounting bracket deflects to the position of the dividing plate and slides out, realizing the screening of the unqualified FPC steel sheet. At the sliding-off place of the screening channel, two collecting boxes are placed to collect the unqualified FPC steel sheets and the qualified FPC steel sheets.

[0016] This utility model includes a material guide channel and a second electric telescopic rod. The inclination of the material guide channel can be adjusted by the second electric telescopic rod, which facilitates the sliding of the FPC steel sheet. A support mechanism is also provided, which includes a first electric telescopic rod, a mounting platform, and a support rod. The height of the screening channel and the material guide channel can be adjusted as a whole by the operation of the first electric telescopic rod, so that it meets the installation requirements of the testing and conveying equipment.

[0025] The sorting mechanism 5 includes a mounting frame 501, which has an L-shaped structure. A roller 502 is evenly rotatably mounted on the bottom of the mounting frame 501.

A swing mechanism that enables the connecting rod 503 to rotate is installed at the bottom of the screening channel 1.

[0026] In this embodiment, the swing mechanism includes a first synchronous wheel 13 driven by a bidirectional motor 12, a second synchronous wheel 15 connected to the first synchronous wheel 13 via a synchronous belt 14, and the second synchronous wheel 15 being coaxially fixed with the connecting rod 503.

[0027] In this embodiment, a motor frame 11 is fixed at the bottom of the screening channel 1, and a bidirectional motor 12 is fixed at the bottom of the motor frame 11. The output shaft of the bidirectional motor 12 is coaxially fixed with the first synchronous pulley 13.

[0028] In this embodiment, a side block 4 is fixed at the bottom of the top end of the screening channel 1 away from the side guard plate 2, and the mounting bracket 501 is in contact with the dividing plate 3 when it is deflected.

[0029] In this embodiment, a second electric telescopic rod 16 is rotatably connected to the bottom of the screening channel 1. The output end of the second electric telescopic rod 16 is rotatably connected to the bottom of the guide channel 6. The guide channel 6 and the second electric telescopic rod 16 are provided. The tilt of the guide channel 6 can be adjusted by the second electric telescopic rod 16, which facilitates the adjustment of the sliding of the FPC steel sheet.

[0030] In this embodiment, a support mechanism 7 is installed below the screening channel 1. The support mechanism 7 includes a mounting platform 9. A first electric telescopic rod 8 is fixed at each of the four corners of the bottom of the mounting platform 9. Support rods 10 are fixed at both ends of the top of the mounting platform 9 on the side away from the dividing plate 3. The height of the screening channel 1 and the material guiding channel 6 can be adjusted as a whole by the operation of the first electric telescopic rod 8 so that it meets the installation requirements of the detection and conveying equipment. The top of the support rod 10 is fixed to the bottom of the screening channel 1, and the two ends of the top of the mounting platform 9 on the side away from the support rod 10 are fixed to the bottom of the screening channel 1 by fixing blocks.

[0031] In this embodiment, a PLC controller 17 is installed on the top of the mounting platform 9, and the PLC controller 17 is electrically connected to the bidirectional motor 12.

[0032] Working Principle: The system comprises a screening channel 1, side guard plate 2, dividing plate 3, side block 4, sorting mechanism 5, guide channel 6, and oscillating mechanism. The oscillating mechanism includes a bidirectional motor 12, a first synchronous pulley 13, a synchronous belt 14, and a second synchronous pulley 15.

The PLC controller 17 is electrically connected to the vision controller. When the industrial camera detects that the FPC steel sheet is unqualified, the vision controller feeds back the detection result to the PLC controller 17. The PLC controller 17 then controls the bidirectional motor 12 to operate. The first synchronous pulley 13 rotates the second synchronous pulley 15 via the synchronous belt 14, thereby causing the mounting frame 501 to oscillate. The mounting frame 501 oscillates to the side block 4. The position allows defective FPC steel sheets to slide off.

The first synchronous pulley 13 rotates the second synchronous pulley 15 via the synchronous belt 14. The mounting bracket 501 deflects to the position of the dividing plate 3, causing it to slide out, thus screening defective FPC steel sheets. Two collection boxes are placed at the sliding point of the screening channel 1 to collect defective and qualified FPC steel sheets. A guide channel 6 and a second electric telescopic rod 16 are provided. The inclination of the guide channel 6 can be adjusted by the second electric telescopic rod 16 to facilitate the sliding of the FPC steel sheets. It can also be adjusted according to the height of the FPC steel sheet inspection and conveying equipment to make the guide channel 6 fit the inspection and conveying equipment.

[0033] The detection and conveying equipment is an existing technology, featuring an industrial camera, sensors, and an intelligent vision controller. This equipment is installed at the end of the detection and conveying equipment and electrically connected to it to achieve program control.
