Description

Technical Field

[0001] The utility model belongs to the technical field of flexible printed circuit board quality detection, and particularly relates to a flexible printed circuit board quality detector. Background Technique

[0002] Flexible printed circuit boards, also known as flexible circuit boards or flex printed circuit boards, are favored for their excellent characteristics such as light weight, thin thickness, and free bending and folding. They are a kind of printed circuit with high reliability and excellent flexibility made of polyester film or polyimide as the substrate. By embedding circuit designs on flexible and thin plastic sheets, a large number of precision components can be stacked and embedded in narrow and limited spaces, thus forming a flexible circuit. Such a circuit can be bent and folded at will, with light weight, small volume, good heat dissipation, and convenient installation, breaking through the traditional interconnection technology. In the structure of a flexible circuit, the materials used are insulating films, conductors, and adhesives.

[0003] In the prior art, there is a flexible printed circuit board quality detector with the patent publication number CN218296991U. The above patent includes a conveyor belt. Two groups of drive shafts are symmetrically arranged at both ends inside the conveyor belt, a support shaft is arranged in the middle inside the conveyor belt, two groups of side plates are symmetrically arranged on both sides of the conveyor belt, and a detection mechanism with a function of measuring values is arranged on the conveyor belt. As the flexible printed circuit board moves, the flexible printed circuit board will squeeze the rotating pressure-bearing columns. The pressure-bearing columns push the brackets, and the brackets drive two groups of sliding plates to slide along two groups of guide columns and compress the springs. Under the action of the rebound force of the springs, the pressure-bearing columns tightly press the flexible printed circuit board, making the flexible printed circuit board closely attached to the conveyor belt. At the same time, a moving sliding plate drives the movable outer jaws on the vernier caliper to move, so that the display on the vernier caliper shows a value. By observing the value, if the value is not within the qualified value range, it is determined that the flexible printed circuit board is unqualified; otherwise, it is determined that the flexible printed circuit board is qualified, realizing the detection of the flexible printed circuit board. However, there are still the following deficiencies in actual use: In practice, when the device detects the flexible printed circuit board, it conveys it through a conveyor belt, and the conveying position of the flexible printed circuit board cannot be corrected during the conveying process, which will reduce the detection accuracy due to position deviation during the conveying and detection. Moreover, when detecting the flexible printed circuit board, its width cannot be detected, reducing the detection efficiency.

[0004] Therefore, a flexible printed circuit board quality detector is needed to solve the problems of inability to perform conveying correction and inability to detect the corresponding width in the prior art. Content of the Utility Model

[0020] The following further describes the present utility model in conjunction with embodiments.

[0021] Please refer to Figures 1-4 , the present utility model provides a flexible printed circuit board quality inspection machine, including a conveyor device 1, a thickness detection device 2 is installed on the left side of the conveyor device 1, an adjustment mechanism 3 is installed on the upper part of the conveyor device 1 on the right side of the thickness detection device 2, and a limiting mechanism 4 is arranged on the adjustment mechanism 3 and is arranged on the right side of the thickness detection device 2.

[0022] During use, through the adjustment mechanism 3, the conveying position of the flexible printed circuit board can be limited according to its specifications, so as to improve the unity of its conveying, facilitate accurate detection work through the thickness detection device 2, and at the same time, through the limiting mechanism 4, when the flexible printed circuit board passes through it, through an external control display device, the width of the flexible printed circuit board can be detected according to its change situation, so as to improve the comprehensiveness of detection, and thus improve the production efficiency.

[0023] Furthermore, as in Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically explaining that the adjusting mechanism 3 includes an electric telescopic rod 301. The electric telescopic rod 301 is fixedly installed on the upper part of the conveying device 1. The end of the electric telescopic rod 301 is fixedly connected with an adjusting plate 302. A connecting groove 303 is opened on the left side of the adjusting plate 302. The limiting mechanism 4 is arranged on the adjusting mechanism 3 through the connecting groove 303. There are four electric telescopic rods 301, and the four electric telescopic rods 301 are arranged in two groups of two. The two groups of electric telescopic rods 301 are symmetrically arranged front and back on the conveying device 1.

[0024] During use, the electric telescopic rod 301 runs to push the adjusting plate 302 to move, enabling it to make adaptive adjustments according to the specifications of the flexible circuit board, so that the flexible circuit board can maintain position correction during conveying, and thus improve the detection accuracy when detected by the thickness detection device 2.

[0025] According to the above working process, it can be seen that: through the provided adjusting mechanism 3, the conveying can be adjusted according to the specifications of the conveyed flexible circuit board to improve the accuracy of the subsequent thickness detection device 2.

[0026] Furthermore, as shown in Figure 2 、 Figure 3 and Figure 4 it is worth specifically explaining that the limiting mechanism 4 includes an installation opening 401. The installation opening 401 is opened on the adjusting plate 302 and is arranged at the connecting groove 303. A fixed plate 402 is fixedly connected to the right side of the installation opening 401 on the adjusting plate 302. A sliding rod 403 is slidably arranged through the fixed plate 402. A limiting plate 404 is fixedly connected to the right end of the sliding rod 403. A spring 405 is sleeved on the outer side of the sliding rod 403. A C-shaped plate 406 is fixedly connected to the left end of the sliding rod 403 and is slidably arranged on the adjusting plate 302 through the installation opening 401. A rotating shaft 408 is fixedly connected to the C-shaped plate 406. A support rod 409 is rotatably connected to the rotating shaft 408. One end of the support rod 409 away from the rotating shaft 408 is rotatably connected to an adapter plate 4010. A limiting rod 4011 is fixedly connected to the adapter plate 4010. The right end of the limiting rod 4011 is rotatably connected to a fixed shaft 407. The fixed shaft 407 is fixedly connected to the connecting groove 303. An installation groove 4012 is opened on the left part of the outer side of the limiting rod 4011. A roller 4013 is rotatably connected in the installation groove 4012. The limiting rod 4011 is specially shaped, and there are multiple rollers 4013. The multiple rollers 4013 are arranged in the installation groove 4012.

[0027] During use, due to the setting of the roller 4013, when the flexible circuit board passes through it, the roller 4013 can roll and convey it. And due to the extrusion of the flexible circuit board on the roller 4013, the limiting rod 4011 rotates on the fixed shaft 407, so that the limiting rod 4011 squeezes the C-shaped plate 406 through the support rod 409. Further, the C-shaped plate 406 squeezes and moves the sliding rod 403 to make it slide on the fixed plate 402, thereby squeezing the spring 405 to a certain extent to cause it to deform. When the elastic force of the spring 405 is restored, it can also return to its initial state after the detection is completed. Through the sliding of the C-shaped plate 406 and in cooperation with an external controller, the width of the conveyed flexible circuit board can be detected to check whether it meets the standard, thus improving the comprehensiveness of the detection work.

[0028] This solution has the following working process: When this device is in use, the flexible circuit board is conveyed by the conveying device 1. At this time, the electric telescopic rod 301 operates to push the adjusting plate 302 to move, enabling it to make adaptive adjustments according to the specifications of the flexible circuit board, so that the flexible circuit board can maintain position correction during conveyance. Furthermore, when detected by the thickness detection device 2, the detection accuracy can be improved. At the same time, due to the setting of the roller 4013, when the flexible circuit board passes through it, the roller 4013 can roll and convey it. And due to the extrusion of the flexible circuit board on the roller 4013, the limiting rod 4011 rotates on the fixed shaft 407, so that the limiting rod 4011 squeezes the C-shaped plate 406 through the support rod 409. Further, the C-shaped plate 406 squeezes and moves the sliding rod 403 to make it slide on the fixed plate 402, thereby squeezing the spring 405 to a certain extent to cause it to deform. Through the sliding of the C-shaped plate 406 and in cooperation with an external controller, the width of the conveyed flexible circuit board can be detected to check whether it meets the standard, thus improving the comprehensiveness of the detection work.

[0029] In summary: Through the provided adjustment mechanism 3, the conveyance can be adjusted according to the specifications of the conveyed flexible circuit board to improve the accuracy of subsequent detection by the thickness detection device 2. Through the provided limiting mechanism 4, in cooperation with the adjustment mechanism 3 to correct the conveyance position of the flexible circuit board, the width of the flexible circuit board can be detected to ensure the detection efficiency and further improve the production efficiency.
