[0016] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0017] Please refer to Figure 1 as well as Figure 2 The present invention provides a method for detecting a flexible circuit board, which comprises the following steps: S1: Obtain a target product to be tested, and place the target product to be tested on a loading platform 2; S2: transferring the target product to be tested from the loading platform to the testing platform to perform a first test on the target product to be tested; S3: transferring the target product after the test from the test platform to an automatic rotating device; S4: If there are unqualified products among the target products after the test, the automatic rotating device is rotated by a preset angle to send the target products to the test platform again for retesting.

[0018] From the above description, it can be seen that the beneficial effect of the present invention is that the target product to be tested (i.e., FPC) is placed on the test platform through the material picking piece, the FPC is tested in sequence, and after the test, the target product is adsorbed onto the automatic rotating device through the material picking piece. On this basis, the automatic rotating device automatically rotates a preset angle (such as 180°) for retesting, and through a one-step quick operation confirmation, it reduces the repeated loading and unloading of personnel, thereby improving the efficiency of FPC testing. At the same time, after multiple tests and verifications on the flexible circuit board, it can more effectively intercept the outflow of products with poor functions. It should be noted that in actual applications, after the first test of the target product, misjudgment and the like may occur, and the test accuracy can be improved by retesting. In addition, before retesting, the target product is rotated by a preset angle through the automatic rotating device, so that the retest can test different positions of the flexible circuit board, thereby improving the test accuracy.

[0019] Furthermore, the method for inspecting a flexible circuit board of the present invention further includes the following steps: if there are no unqualified products among the target products, the target products are transferred from the automatic rotating device to the receiving device.

[0020] From the above description, it can be seen that if there are no unqualified products, the target products are directly transferred to the receiving device (i.e., the tested placement area on the testing equipment) without the need for retesting, thereby improving efficiency.

[0021] Furthermore, the method for detecting a flexible circuit board of the present invention further includes the following steps: after retesting the unqualified products, if there are unqualified products in the retest, the unqualified products in the retest are marked.

[0022] As can be seen from the above description, marking the products that failed the retest is convenient for distinguishing the products that passed the retest and the products that failed the retest. It should be noted that the target product includes at least one flexible circuit board. In actual applications, multiple flexible circuit boards are tested at one time. No marking is done after the first test. All flexible circuit boards are retested after rotating 180 degrees. The final test result of the flexible circuit board is based on the result of the second test (i.e., retest). After the second test, the equipment will mark (such as stamp) the products that failed the retest among the target products.

[0023] Furthermore, in the flexible circuit board detection method described in the present invention, in step S4, the target product is sent to the test platform again for retesting, including the following steps: transferring the target product from the automatic rotating device to the test platform by picking up the material, retesting the target product by the test platform, and judging whether there are any products that fail the retesting among the target products according to the retesting results.

[0024] In actual applications, the target product is tested in sequence. After the test, the target product is retrieved by a material picker (such as a robot) and placed on an automatic rotating device. After rotating 180 degrees, the robot sends the target product to the test platform for retesting in sequence.

[0025] Correspondingly, another object of the present invention is to provide a detection device for a flexible circuit board, which includes a frame body 1, on which a test platform 3 and an automatic rotation device are provided, and the automatic rotation device includes a rotating platform 4, a rotating screw 5 and a driving member 6, and the driving member 6 is arranged in the frame body 1, one end of the rotating screw 5 is connected to the rotating platform 4, and the other end of the rotating screw 5 is transmission-connected to the driving member 6.

[0026] As can be seen from the above description, a corresponding test platform 3 and an automatic rotating device are provided, and after the target product is tested for the first time on the test platform 3, it can be transferred to the rotating platform 4 of the automatic rotating device. Since the automatic rotating device includes the rotating platform 4, the rotating screw 5 and the driving member 6, etc., the rotating screw 5 is driven to rotate by the driving member 6 (such as a rotating motor), and then the rotating platform 4 is driven to rotate, so as to realize the rotation of the automatic rotating device, so as to send the target product to the test platform again for retesting.

[0027] Furthermore, in the flexible circuit board detection equipment described in the present invention, the automatic rotation device also includes a gear assembly and a transmission member 8 (such as a belt), the gear assembly is connected to the rotating screw and the transmission member respectively, and the end of the transmission member away from the gear assembly is connected to the driving member.

[0028] In practical applications, the gear assembly may include a first gear, a first rotating shaft, and a second gear, wherein the first gear is sleeved on the first rotating shaft, the second gear is sleeved on the rotating screw, and the first gear and the second gear are meshed and connected. One end of the transmission member is connected to the driving member, and the other end is connected to the first rotating shaft. In practical applications, the driving member (such as a rotating motor) drives the first rotating shaft to rotate through the transmission member 8, the first rotating shaft drives the first gear to rotate, the first gear rotates to drive the second gear to rotate, the second gear rotates to drive the rotating screw to rotate, and then drives the rotating platform to rotate, thereby realizing the preset angle of rotation of the target product located on the rotating platform. In addition, the automatic rotating device can also rotate bearings, etc.

[0029] It can be seen from the above description that by providing corresponding transmission members 8 and gear components 7 , etc., the transmission connection between the driving member 6 and the rotating screw 5 can be effectively achieved.

[0030] Furthermore, the flexible circuit board detection device described in the present invention also includes a loading platform 2, and the loading platform 2 is arranged on the frame body.

[0031] Furthermore, the flexible circuit board detection device of the present invention further includes a material receiving device 9, which is arranged on the frame body. It should be noted that the position of the material receiving device on the frame body can be selected according to actual conditions, such as being arranged below the frame body.

[0032] It can be seen from the above description that a corresponding material receiving device 9 is provided to facilitate receiving the target product.

[0033] Furthermore, the flexible circuit board detection device described in the present invention also includes a material moving mechanism, which includes a material moving track and a material picking piece. The material moving track is arranged on the frame body 1, and the material picking piece is movably arranged on the material moving track.

[0034] From the above description, it can be seen that by setting up a corresponding material transfer mechanism, during the testing of the flexible circuit board, the product can be grabbed / adsorbed by a material picking part (such as an adsorption part, a manipulator), and then the product can be delivered to each platform / device through the corresponding material transfer track.

[0035] Furthermore, the flexible circuit board detection device described in the present invention also includes a marking component, and the marking component is arranged on the test platform 3.

[0036] It can be seen from the above description that a corresponding marking component is provided, and the marking component is used to mark the products that fail the retest, so as to facilitate their distinction.

[0037] It should be noted that before testing the flexible circuit board, it is necessary to first draw a picture, select materials, and so on (such as selecting a suitable rotating motor, transmission parts, and rotating screw 5, etc.), and then assemble the above materials. Specifically, the rotating motor can be fixed at the bottom of the frame body (i.e., the working platform), and the rotating screw 5 can be set at the bottom of the rotating platform, and the rotating screw 5 can be connected to the rotating motor by a transmission part. After the rotating motor and the screw are fixed, the equipment is debugged.

[0038] In summary, the detection method and detection equipment of the flexible circuit board provided by the present invention: (1) After the FPC is automatically rotated by 180°, the product retest function is performed. Specifically: by designing and adding a rotating motor (i.e., an automatic rotating device), the FPC to be tested is placed on the test platform 3 by a manipulator, and the test is carried out in sequence. After the test, the product is adsorbed onto the automatic rotating device by the manipulator, and the automatic rotating device automatically rotates 180° to send the target product to the test platform again for retesting. The one-step fast operation confirmation reduces the repeated loading and unloading of personnel and improves the FPC test efficiency. (2) Solve the problem of manual secondary loading and unloading of FPC functional testing. After testing and verification, it can effectively intercept the outflow of functional defects, and the ET test efficiency can be improved by 30%. After each product of the present invention is tested, the defective product is automatically rotated by 180° by the equipment for automatic retesting, so as to test different detection areas (test points) of the product, improve the test accuracy, effectively control various defective outflows in the inspection FPC process, improve the ET test efficiency and achieve standardization.
