An FPC product appearance detection device based on fly shooting of tray

Abstract

The present invention provides an FPC product appearance detection device based on tray plate flying shooting, which is characterized by comprising a lower machine platform, a feeding mechanism, a front detection mechanism, a turning plate mechanism, a back detection mechanism and a discharging mechanism. Among them, in the front detection mechanism and the back detection mechanism, a multiple image detection module is adopted to make the detection more accurate, and combined with the flying shooting detection technology, it is independently controlled by an independent flying shooting controller, and the detection is faster. In the turning plate mechanism, by only driving the tray plate to turn over and isolating and sucking a single tray plate, it is prevented that the tray plate is taken or turned over wrongly due to shaking or other reasons.

Description

Technical Field

[0001] The present invention relates to, and in particular to, an FPC product appearance detection device based on tray flying shooting. Background Art

[0002] In order to be used in the final product, flexible circuit board products need to go through processes such as SMT patching, and screen printing, dispensing, and mounting various components are carried out on the original pure bare board. After a whole piece of FPC is mounted, it is cut into individual products for use in different electronic products. Due to the complex processes, a large number of product defect problems will occur. Therefore, the common practice is to place these products on individual tray plates and then manually detect them one by one. Due to the small size and many details of the products, the detection efficiency is very low. There are also some detection devices for this product on the market currently, but they mostly complete the automated operation and do not guarantee the detection effect well.

[0003] In addition: Due to the complex defects of FPC products, a combination of multiple light sources is required to present a good image effect for easy detection; since there are multiple FPC products on one tray plate and multiple light sources are required for exposure shooting in imaging, the fixed-point shooting method is often used, which will cause a long time-consuming and affect the efficiency.

[0004] In order to ensure the detection accuracy and improve the detection efficiency at the same time, we have designed a fully automatic detection device based on tray flying shooting, which can achieve high-precision automated detection, improve the detection speed, and enhance the efficiency.

[0084] In this embodiment,

[0087] The lifting module is controlled by the lifting motor 2-2. In the middle is the jacking mechanism 2-3, and a tray product carrier 2-4 is arranged above it. The lifting module is installed below the loading conveyor line 2-1 and is used for jacking and moving the tray products to move the products to the designated positions.

[0088] The loading conveyor line 2-1 conveys the tray products through a rotating belt and moves the products to the designated positions.

[0089] The front detection mechanism 3 mainly uses the aluminum-profile first gantry 3-1 as the chassis, on which the first multi-imaging photographing module 3-3, the first X-axis moving module 3-4, the first Y-axis moving module 3-5, and the first Tray tray in-and-out conveyor line 3-2 are supported.

[0090] The first gantry 3-1 is fixed on the entire lower machine table 1 and supports the first detection module above.

[0091] The first detection module: The first multi-imaging photographing module 3-3 successively includes the first camera, the first bowl light, the first coaxial light, and the first ring light from top to bottom.

[0092] The first X-axis moving module 3-4 and the first Y-axis moving module 3-5 are fixed on the first gantry 3-1 for forward and backward as well as left and right movements.

[0093] The first Tray tray in-and-out conveying line 3-2 is provided with first positioning blocks 3-7 at the front and back for fixing the product position to prevent the product from moving forward and backward under inertia.

[0094] In this embodiment, the structures of the front detection mechanism 3 and the back detection mechanism 5 are the same.

[0095] The manipulator 4-1-3 moves forward and backward through the linear guide 4-1-7. On the manipulator 4-1-3, a nozzle mounting and adjusting plate 4-1-4 is installed, on which the installation position of the nozzle 4-1-5 can be set. There is a corresponding nozzle 4-1-5 under the nozzle mounting and adjusting plate 4-1-4 for sucking the tray. A pressing carrier 4-1-6 is arranged under the manipulator 4-1-3 to press the empty tray after it is placed.

[0096] The specific usage method of the device in this embodiment is as follows:

[0097] Loading mechanism 2:

[0098] 1. Manually place the tray on the tray product carrier 2-4, and the product limiting components 2-7 around limit the product position.

[0099] 2. After the product is manually placed, the lifting motor 2-2 starts to work. The bottom tray is lifted by the lifting module to lift the tray product carrier 2-4 and place the tray product on the loading conveying line 2-1.

[0100] 3. The product is conveyed to the front detection mechanism 3 through the movement of the loading conveying line 2-1.

[0101] Front detection mechanism 3:

[0102] 1. The first Tray tray in-and-out conveying line 3-2 conveys the tray product to the designated position and then stops.

[0103] 2. After the lifting system (similar to the lifting module of the loading mechanism 2) below the front detection mechanism 3 lifts the tray to the designated position, the first positioning block 3-7 performs precise positioning.

[0104] 3. After the tray is positioned, the front detection mechanism 3 starts to work.

[0105] 4. The tray is rectangular, and each product needs to be detected. The product is controlled to move sequentially along the X and Y axes by the first X-axis moving module 3-4 and the first Y-axis moving module 3-5 to photograph the product.

[0106] In the conventional fixed-point shooting method, after moving into position, the object may shake, and it is necessary to wait for the object to stop before taking another photo, resulting in low efficiency. Through the first flying shooting controller 3-6, during the high-speed movement process, the first camera is continuously triggered to take photos multiple times through multiple set positions. During the movement of the first camera and the asynchronous exposure of the three light sources in the first multi-image shooting module 3-3, uniform shooting is performed to complete the shooting of the entire tray product, which can effectively improve efficiency.

[0107] 5. The tray flows to the turning mechanism 4 through the first tray in-out conveyor line 3-2;

[0108] Turning mechanism 4:

[0109] 1. The manipulator 4-1-3 takes a mirror empty tray from the empty tray loading carrier 4-3-3 and waits at the designated position;

[0110] 2. After the front detection product is detected, the first tray in-out conveyor line 3-2 transports the product to the designated position, and the lifting module 4-1-1 lifts the product to the designated position;

[0111] 3. The manipulator 4-1-3 puts down the empty tray to cover the tray with the product, and then the manipulator 4-1-3 moves to the designated position and waits;

[0112] 4. The flipping module 4-2 fixedly clamps the two trays and flips them;

[0113] 4.1. When the upper limit mechanism 4-2-3 of the front and back trays is accurately positioned, the clamping mechanism around starts to work, and the clamping jaw cylinder 4-2-1 drives the clamping plate 4-2-3 to clamp the front and back trays;

[0114] 4.2. The synchronous belt 4-2-4 drives the front and back trays to start rotating 180 degrees;

[0115] 4.3. The lifting module 4-1-1 jacks up and supports the front and back trays, and the clamping plate 4-2-3 is released to complete the flipping action;

[0116] 5. The manipulator 4-1-3 moves to the designated position to pick up the flipped tray and places it on the empty tray unloading carrier 4-3-6;

[0117] 6. After the manipulator 4-1-3 picks up the tray, the lifting module 4-1-1 starts to move downwards and puts the tray back on the conveyor line on the turning mechanism 4;

[0118] 7. The flipped tray moves to the back detection mechanism 5 through the conveyor line on the turning mechanism 4;

[0119] Back surface inspection mechanism 5 and blanking mechanism 6:

[0120] After the turning plate, the product enters the back surface inspection mechanism 5;

[0121] The back surface inspection steps are similar to the front surface inspection steps.

[0122] After completion, the product flows to the blanking mechanism 6, and the tray disks are stacked together. When the limit is reached, the operator takes away the tray disk with the product.

[0123] In this embodiment,

[0124] 1. Manually pull out the drawer slide rail 4-3-5, place the empty Tray disk product on the empty disk loading carrier 4-3-3, and then push the drawer slide rail 4-3-5 back in to complete the placement of the empty tray disk. Adjust the size by turning the handwheel 4-3-4 to be compatible with different models of Tray disk products;

[0125] 2. The lifting module 4-1-1 drives the Tray disk product to move upward. The ray disk product is controlled to stop at a suitable position by the sensor 4-3-2. The fixing block 4-3-1 is pushed forward to fix the topmost tray disk, so as not to affect the movement of the lower tray disks when the manipulator 4-1-3 sucks, and the other tray disks move downward;

[0126] 3. The empty disk blanking carrier 4-3-6 moves to the top. After the manipulator 4-1-3 puts down the empty tray disk, it moves downward with the empty tray disk;

[0127] 4. After the empty disk blanking carrier 4-3-6 is full, the operator takes it away.

[0128] It should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
