Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

The invention provides a full-automatic FPC visual detection and laser device.

In the embodiment of the present invention, as shown in fig. 1 to 14, the full-automatic FPC visual inspection and laser apparatus includes a body 100, and an upper bin 200, a feeding robot 400, a carrying table 600, a visual inspection system 700, a transfer robot 800, a processing table 900, an inverting robot 110, a laser system 120, a discharging robot 130, a lower bin 140, and a defective bin 150 mounted on the body 100.

Referring to fig. 3, the upper bin 200 is used for storing the plate 160 to be processed. It should be understood that the board material to be processed 160 refers to a flexible circuit board which has not been processed yet.

Since the flexible circuit board is widely used in some smart products (e.g., mobile phones, headsets, tablet computers, game consoles, etc.), different smart products have different requirements on the size of the flexible circuit board, so that the upper storage bin 200 can store flexible circuit boards with different sizes, in some embodiments, the size of the loading cavity 200a for storing the board 160 on the upper storage bin 200 can be adjusted.

In practical implementation, the loading bin 200 includes a loading plate 200b, the loading plate 200b includes a plurality of guide slots 200c, the plurality of guide slots 200c respectively extend from the center of the loading plate 200b to the periphery of the loading plate 200b, each guide slot 200c is provided with a movable guide rod 200d therein, and the plurality of guide rods 200d and the loading plate 200b cooperate to form a loading cavity 200a. In practical implementation, the guide groove 200c may extend in a length direction, a width direction, a diagonal direction, and the like of the loading plate 200b, and is not particularly limited herein. Specifically, when the plate 160 is placed on the loading plate 200b, the guide bar 200d contacts the periphery of the plate 160 and restricts the movement of the plate 160. It can be understood that, the manner that the guide rods 200d of the rod-shaped structure and the material loading plate 200b of the plate-shaped structure cooperate to form the material loading cavity 200a is beneficial to the staff to observe the residual amount of the plates 160 in the material loading cavity 200a through the gap between the two adjacent guide rods 200d, on the other hand, the gap between the two adjacent guide rods 200d is also convenient for the user to put the plates 160 into the material loading cavity 200a by the arm, and meanwhile, compared with the manner that the material loading cavity 200a is formed by the plate-shaped structure and the material loading plate 200b, the guide rods 200d of the rod-shaped structure can effectively reduce the overall weight of the material loading bin 200.

Considering that most of the plates 160 used in the manufacturing process are rectangular, in order to facilitate the adjustment of the shape of the loading cavity 200a by the worker according to the shape of the plate 160, in some embodiments, a portion of the guide grooves 200c extend along the length direction of the loading plate 200b, and another portion of the guide grooves 200c extend along the width direction of the loading plate 200 b. Therefore, the length of the rectangular feeding cavity 200a can be adjusted by adjusting the guide rods 200d in the guide grooves 200c with different extension directions, and the method is simple and convenient.

In specific implementation, in some embodiments, a ball screw 200e in transmission connection with the guide rod 200d may be disposed on a side of the loading plate 200b opposite to the loading cavity 200a, and a rotatable knob 200f is disposed on the ball screw 200e, so that the guide rod 200d can move and be fixed in the guide groove 200c by converting a rotary motion of the knob 200f into a linear motion of the guide rod 200d based on the ball screw 200 e; in other embodiments, a mounting plate (not shown) may also be disposed on a side of the material loading plate 200b opposite to the material loading cavity 200a, a plurality of slot bodies (not shown) into which the guide rod 200d is inserted are disposed on the mounting plate, the plurality of slot bodies are arranged in a row, the plurality of slot bodies and the guide slot 200c are disposed in parallel, and the guide rod 200d may be selectively inserted into any one slot body, so as to achieve the purpose of moving and fixing the guide rod 200d in the guide slot 200 c. Since there are various ways to realize the movement and fixation of the guide bar 200d in the guide groove 200c, this is not an example.

During the process of production, the plates 160 are stacked together, and at this time, in order to prevent the units on the plates 160 from being worn due to mutual friction between two adjacent plates 160, a separation paper 170 is placed between two adjacent plates 160, and the two plates 160 are separated by the separation paper 170, so as to protect the units on the plates 160. In view of this, in some embodiments, the fully automatic FPC visual inspection and laser apparatus further includes a paper separation bin 300 and a paper separation handling robot 500, wherein the paper separation 170 is placed between any two adjacent to-be-processed boards 160 in the stacked boards 160 to be processed, the paper separation bin 300 is used for storing the paper separation 170, and the paper separation handling robot 500 is used for handling the paper separation 170 in the loading bin 200 to the paper separation bin 300. In the actual production process, the separating paper carrying robot 500 carries the separating paper 170 from the loading chamber 200a to the separating paper bin 300, and then the loading robot 400 carries the plate material 160 in the loading chamber 200a to the carrying platform 600.

In order to reduce the difficulty of developing the product, in some embodiments, the structure of the paper separation bin 300 is the same as or substantially the same as that of the upper bin 200, that is, the specific structure of the paper separation bin 300 may refer to the structure of the upper bin 200, and will not be described herein again.

Referring to fig. 5, the loading robot 400 is used for transporting the plate 160 to be processed in the loading bin 200 to the material conveying platform 600. In specific implementation, in some embodiments, the feeding robot 400 carries the plate 160 by vacuum suction, and specifically, the feeding robot 400 includes a through stepping motor 400a, a sensor 400b, a plurality of vacuum chucks 400c, and the like as shown in fig. 5, when the feeding robot 400 moves above the feeding chamber 200a, the through stepping motor 400a drives the vacuum chucks 400c to descend, the sensor 400b stops the through stepping motor 400a when sensing that the vacuum chucks 400c descend to the position, the vacuum chucks 400c operate again to take away the plate 160 in the feeding chamber 200a, and then leave the feeding chamber 200a and place the taken-away plate 160 on the material carrying platform 600. Of course, the design of the present invention is not limited thereto, and in other embodiments, the feeding robot 400 may also transport the plate 160 by clamping, and is not limited thereto.

To reduce the difficulty of developing the product, in some embodiments, the structure of the separating paper carrying robot 500 may be the same or substantially the same as that of the loading robot 400.

Referring to fig. 6, a material conveying table 600 is used for conveying the sheet 160 to be processed to a vision inspection system 700. During specific implementation, fortune material platform 600 is including fortune flitch 600a, two jacking cylinders 600b and two linear electric motor 600c, fortune flitch 600a is used for bearing panel 160, two jacking cylinders 600b are located fortune flitch 600a relative both sides respectively, in order when panel 160 places on fortune flitch 600a, push up panel 160 in the both sides of panel 160, this is favorable to preventing that panel 160 from removing on fortune flitch 600a, thereby guarantee the smooth execution of subsequent visual detection's process, two linear electric motor 600c locate the relative both sides of jacking cylinder 600b respectively, and be connected with jacking cylinder 600b transmission, keep away from each other or be close to with two jacking cylinders 600b of drive.

Preferably, the material of the material conveying plate 600a is transparent material (such as, but not limited to, high transparent glass, plastic, etc.), so that the visual inspection system 700 can visually inspect the material 160 directly on the front and back surfaces of the material conveying plate 600a, thereby eliminating the process of turning over the material 160 on the material conveying plate 600a and facilitating the rapid operation of the visual inspection system 700.

The vision inspection system 700 is used to identify the location of the rejected units on the obverse and reverse sides of the sheet 160 to be processed and to transmit the location information to the laser system 120.

Referring to fig. 7 and 8, in an implementation, the vision inspection system 700 includes a front side vision inspection mechanism 1 and a back side vision inspection mechanism 2. The front visual inspection mechanism 1 is used for identifying the scrapped unit positions on the front side of the plate 160 to be processed, and the back visual inspection mechanism 2 is used for identifying the scrapped unit positions on the back side of the plate 160 to be processed, and both can be in contact with the laser system 120 to transmit information.

Specifically, positive visual inspection mechanism 1 includes positive CCD camera 11 and first light filling lamp 12, and positive CCD camera 11 and first light filling lamp 12 set up at organism 100's direction of height interval, and just positive CCD camera 11 is located the top of first light filling lamp 12, and the clearance between positive CCD camera 11 and the first light filling lamp 12 is used for supplying fortune flitch 600a to park.

Referring to fig. 9, the transfer robot 800 is used to transfer the plate 160 on the material conveying table 600 to the processing table 900. Specifically, the transfer robot 800 uses a vacuum adsorption method to transport the plate material 160, and in some embodiments, the specific structure of the transfer robot 800 may refer to the loading robot 400, so as to reduce the development cost of the product.

Referring to fig. 10 and 11, the processing table 900 includes two spaced-apart carrier plate mechanisms 3, each carrier plate mechanism 3 includes a carrier 31 and an air draft assembly 32 disposed in the carrier 31, each carrier 31 includes a carrier plate 311 for carrying the plate 160 and a main body 314 disposed on one side of the carrier plate 311, the carrier plate 311 is provided with a plurality of first air vents 312, the main body 314 is provided with a second air vent 313, an air inlet 321 of the air draft assembly 32 is communicated with the plurality of first air vents 312, and an air outlet 322 of the air draft assembly 32 is communicated with the outside of the main body 314 through the second air vent 313. In specific implementation, the air pumping assembly 32 includes an air pump (not shown), and since the air pump is a relatively widely used part in the market, the operation principle and the specific structure thereof are not described herein again, and accordingly, in this embodiment, the air outlet 322 of the air pumping assembly 32 and the air inlet 321 of the air pumping assembly 32 are formed on the air pump.

When the plate 160 is placed on the bearing plate 311, the air pump of the air pumping assembly 32 is started, and the air pressure difference is formed on the two sides of the bearing plate 311, so that the plate 160 can be adsorbed on the bearing plate 311, the plate 160 is prevented from moving on the bearing plate 311, and the plate 160 can be marked on the plate 160 by the laser system 120 accurately.

In some embodiments, the carrying plate 311 may be a honeycomb plate, which is provided to avoid the inconvenience of forming the first air passing holes 312 on the plate.

Preferably, the air outlets 322 of the two air draft assemblies 32 are respectively disposed at two sides of the two carriers 31, which are away from each other, so as to prevent the air blown from one carrier 31 from affecting the stable placement of the plate 160 on the other carrier 31.

When the plate 160 detected by the visual detection system 700 is placed on the carrier 311, the laser system 120 is used to perform laser marking on the front surface of the plate 160 to be processed of the carrier mechanism 3 according to the position information of the front surface of the plate 160 fed back by the visual detection system 700 and identify the marking result marked on the front surface of the plate 160.

Specifically, the laser system 120 performs the laser marking process on the front surface of the plate 160, which includes: and (3) printing a two-dimensional code on the front surface of the plate 160, and blacking or punching scrapped units on the front surface of the plate 160.

Based on the above, in some embodiments, if the laser system 120 determines that the blackened position on the front surface of the plate 160 is not the position of the rejected unit or the blackened position fails to completely cover the position of the rejected unit, it may be determined that the marking result on the front surface of the plate 160 is different from the preset result.

In other embodiments, if the laser system 120 determines that the punched position on the front surface of the sheet material 160 is not the position of the rejected unit, or the punched position is misaligned with the position of the rejected unit, the marking result on the front surface of the sheet material 160 may be considered to be different from the preset result.

In still other embodiments, if the laser system 120 determines that the pattern definition of the printed two-dimensional code is too low, it may be determined that the marking result on the front surface of the sheet 160 is different from the preset result.

When the marking result on the front side of the plate 160 is different from the preset result, the laser system 120 stops laser marking on the back side of the plate 160 to avoid resource loss and time waste, and sends a corresponding signal to the feeding manipulator 130 to control the feeding manipulator 130 to transport the plate to the defective warehouse 150.

When the laser system 120 determines that the marking result of the front surface of the plate 160 is the same as the preset result, the laser system 120 sends a corresponding signal to the flipping robot 110 to control the flipping robot 110 to transfer the plate 160 to the carrier 311 of another carrier mechanism 3.

Specifically, the clamping portions 51 are configured to have a clamping function, for example, but not limited to, a structure such as a clamping plate or a clamping rod, and the driving member 4 drives the clamping portions 51 to move closer to or away from each other, thereby closing or opening the clamps 5, and clamping or releasing the plate material 160 by the clamps 5. It can be understood that, the clamping portion 51 is disposed in a strip shape, which can effectively ensure the contact area between the clamping portion 51 and the plate 160, and further ensure the reliability when the clamping portion 51 clamps the plate 160.

In specific implementation, the clamping portion 51 can be driven by the driving member 4 to translate or rotate, and according to the different movement modes of the clamping portion 51, the driving member 4 can drive the clamping portion 51 electrically, pneumatically or hydraulically, for example, but not limited to, the driving member 4 is a motor, a pneumatic cylinder or a hydraulic cylinder, and in some embodiments, a transmission structure (not shown) can be adaptively arranged between the driving member 4 and the clamping portion 51, and the transmission structure can be a gear, a rack, a screw slider, or the like.
