Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to an automatic detection device for the state of a flexible circuit board applied to the SMT industry. Background Art

[0002] Flexible Printed Circuit (FPC), short for Flexible Printed Circuit, is a type of circuit board made of a flexible substrate. The use of FPC can make circuits more miniaturized and flexible. One of the advantages of FPC is its flexibility, which satisfies the requirements for shaping in industrial applications. After shaping, to ensure that the shape is in the desired state, it is necessary to inspect the state (angle and distance).

[0003] In the process of realizing this application, the inventors found that in the process of detecting the status of the FPC flexible circuit board, there are at least the following problems: because the product to be detected is a flexible product, its status is extremely uncertain, which will have a great impact on the detection results. If the flexible circuit board is manually shaped and then the status is detected, there will be a problem of human contamination of the flexible circuit board.

[0004] In view of this, how to solve the problems of the existing detection of the state of the FPC flexible circuit board, such as the uncertainty of the flexible state and the contamination of the flexible circuit board by manual intervention, has become the subject to be studied and solved by the present utility model. Utility Model Content

[0005] The utility model provides an automatic detection device for the state of a flexible circuit board, which aims to solve the problems of uncertain flexible state and contamination of the flexible circuit board by manual intervention in the existing detection of the state of an FPC flexible circuit board.

[0006] To achieve the above-mentioned purpose, the present invention proposes an automatic detection device for the status of a flexible circuit board, which includes a frame and a product transmission mechanism, a movement mechanism, a pick-and-place mechanism, and a detection mechanism installed on the frame; the frame has a detection station.

[0007] The product transmission mechanism is provided with a carrier having a positioning groove for positioning the flexible circuit board and a positioning column for positioning the fixing plate. The product transmission mechanism drives the carrier to be moved to the inspection station.

[0008] The motion mechanism is a mechanism used to move the pick-and-place mechanism and the detection mechanism into or out of the detection station.

[0009] The pick-and-place mechanism is positioned and installed on the motion mechanism, and the pick-and-place mechanism has an execution end for picking up and placing the fixing piece.

[0010] The detection mechanism is positioned and installed on the motion mechanism, and the detection mechanism includes a collection camera and a light source.

[0011] The automatic status detection equipment is configured as follows: when the carrier is located on the detection station, the motion mechanism drives the pick-up and placement mechanism and the detection mechanism to move above the detection station, the pick-up and placement mechanism positions the fixing plate on the positioning column of the carrier and presses the flexible circuit board, and the acquisition camera and light source of the detection mechanism are aimed above the detection station to automatically detect the status of the part to be detected on the flexible circuit board.

[0012] The relevant contents of this utility model are explained as follows:

[0013] 1. In the above technical solution of the present invention, in order to solve the problems existing in the existing detection of the status of FPC flexible circuit boards, such as uncertainty of the flexible status and contamination of the flexible circuit boards by manual intervention, an automatic detection device for the status of flexible circuit boards is designed. The frame of the automatic detection device for the status of flexible circuit boards is provided with a detection station, and a product transmission mechanism, a movement mechanism, a pick-up and placement mechanism, and a detection mechanism are installed on the frame. The automatic detection device for the status of flexible circuit boards is configured as follows: when the carrier is located on the detection station, the movement mechanism drives the pick-up and placement mechanism and the detection mechanism to move above the detection station, the pick-up and placement mechanism positions the fixing plate on the positioning column of the carrier and presses the flexible circuit board, and the acquisition camera and light source of the detection mechanism are aimed at the detection station to automatically detect the status of the part to be detected of the flexible circuit board. Through the innovative design of the above structure, when inspecting the status (bending angle & distance) of the flexible circuit board (FPC), the motion mechanism is used to drive the pick-and-place mechanism to fix the fixing piece to the flexible circuit board, thereby limiting the irregular deformation of the flexible circuit board, ensuring the product status of the inspection machine during inspection, and making the inspection results more accurate. After the inspection is completed, the fixing piece can be removed, which also avoids contamination of the flexible circuit board by manual picking and placing of the fixing piece; at the same time, by using the motion mechanism to drive the inspection mechanism to the top of the inspection station, the angle and distance of the bent product are detected by using a collection camera instead of manual labor, thereby ensuring the accuracy of the inspection results and avoiding damage to employees' eyesight caused by long-term use of CCD inspection.

[0014] 2. In the above technical solution, the product transmission mechanism includes a belt transmission module, a blocking module and a lifting module. The belt transmission module includes a transmission belt and a transmission motor. The two transmission belts are arranged on the frame from right to left. The blocking module is arranged between the two transmission belts, and the lifting module is arranged on the outside of the two transmission belts. The reasonable structural layout avoids interference during the operation of each mechanism, and at the same time ensures that the carrier is accurately and quickly positioned and fixed to the inspection station.

[0015] 3. In the above technical solution, the blocking module includes a blocking head and a blocking cylinder, and the blocking cylinder drives the blocking head to move in the vertical direction to position the carrier that arrives at the detection station; the lifting module includes a lifting plate and a lifting cylinder, and the lifting cylinder drives the lifting plate to move in the vertical direction to lift and fix the carrier that is blocked and positioned by the blocking module, so as to ensure the stability of the overall operation by the reliable and stable structural arrangement of the blocking module and the lifting module.

[0016] 4. In the above technical solution, the motion mechanism includes a gantry spanning the two transmission belts and fixed to the frame, as well as a first motion module and a second motion module mounted on the gantry. The first motion module is used to drive the pick-and-place mechanism to move vertically up and down, and the second motion module is used to drive the detection mechanism to move forward and backward. This structural design enables the motion mechanism to better move the pick-and-place mechanism and the detection mechanism into or out of the detection station, and can perform precise, reliable, stable, and rapid transfer, thereby improving detection efficiency and accuracy.

[0017] 5. In the above technical solution, the pick-and-place mechanism includes a pick-and-place bracket, and the execution end is arranged at the left and right ends of the lower surface of the pick-and-place bracket. The execution end is a suction nozzle, which is adapted to the left and right flexible circuit boards or the left and right positions on the carrier where pressing and status detection are required. At the same time, a suction nozzle is used, and the suction nozzle is connected to external compressed air, which makes the structure more efficient, simpler and lower in cost.

[0018] 6. In the above technical solution, the fixing plate is a plastic steel plate, so as to improve the strength and precision of the fixing plate itself.
