[0029] The working schematic diagram of the device can refer to Figure 5 The plate-shaped workpiece 101 is placed on the conveying belt 3, and the belt roller 2 is driven to rotate by the first motor 4, and the conveying belt 3 can be driven to operate and convey the plate-shaped workpiece 101 on it. Two conveying rollers 9 are driven to rotate synchronously and reversely by the driving mechanism, and the film 8 on the reel 7 can be continuously pulled out by two conveying rollers 9.

[0030] The working principle of the image detection device 13 is mainly based on machine vision technology. The image detection device 13 converts the workpiece to be detected into an image signal through an image acquisition device, and then transmits the image signal to a dedicated image processing system. The image processing system converts the image signal into a digital signal according to the pixel distribution, brightness, color and other information, and performs various operations to extract the characteristics of the target. Finally, according to the preset film pasting state, the image processing system outputs the result, outputs the qualified or unqualified result, thereby realizing the automatic recognition function. The structure of the image detection device 13 includes a camera installed on the support 6, which converts the workpiece on the conveying belt 3 into an image signal. It also includes an image acquisition card for receiving the image signal transmitted by the image acquisition device and converting it into a digital format, and then transmitting it to the image processing system for further processing.

[0031] The device can quickly and accurately identify whether the workpiece is pasted with film and the quality of the pasted film through the image detection device 13, thereby avoiding the tediousness and time consumption of manual detection.

[0032] The driving mechanism includes two connecting shafts 14 rotatably installed on the support 6, the connecting shafts 14 are fixedly connected with the conveying rollers 9, the connecting shafts 14 are fixedly connected with driving wheels 15, the two driving wheels 15 are engaged, the end of the lower connecting shaft 14 is fixedly connected with a driven wheel 16, a second motor 17 is fixedly installed on the support 6, a driving wheel 18 is fixedly installed on the output shaft end of the second motor 17, and the driving wheel 18 is engaged with the driven wheel 16. The number of teeth of the driving wheel 18 is less than the number of teeth of the driven wheel 16, and the driving wheel 18 is decelerated to the driven wheel 16.

[0033] The driving wheel 18 is driven to rotate by the second motor 17, the driving wheel 18 is decelerated to the driven wheel 16, the driven wheel 16 and the connecting shaft 14 are synchronously rotated, the other connecting shaft 14 is driven to rotate by the two driving wheels 15, thereby driving the two connecting shafts 14 to synchronously rotate and reverse, thereby driving the two conveying rollers 9 to synchronously rotate and reverse, and the two conveying rollers 9 can continuously pull out the film 8 on the reel 7. By setting the deceleration transmission mode, the film 8 is pulled out at a slow speed, thereby avoiding the decrease of the film pasting quality caused by the too fast pulling speed of the film 8.

[0034] The device can automatically perform the film pulling operation, so that the film can be continuously and stably pulled out without manual intervention, thereby greatly improving the production efficiency. At the same time, it can ensure that the film is pulled out at a constant speed and tension, thereby avoiding the film quality problems caused by unstable film pulling.

[0035] The conveying roller 9 is provided with a pressing roller 10 on one side, and the pressing roller 10 is located at the upper end of the conveying belt 3. Two spring expansion rods 11 are fixedly installed on the support 6 and are spaced apart. The movable end of the spring expansion rod 11 is fixedly connected to the pressing roller 10. A cutter 12 is fixedly installed on the pressing roller 10. A moving mechanism is arranged on the support 6 and is connected to the pressing roller 10 and used to drive the pressing roller 10 to move up and down. The moving mechanism includes two electromagnets 19 which are fixedly installed on the support 6 and are spaced apart. Magnets 20 are fixedly connected to the two ends of the bottom of the pressing roller 10. The same side magnets 20 are arranged opposite to the electromagnets 19.

[0036] Before the film pasting work starts, one end of the film is pulled to the lower end of the pressing roller 10. The first motor 4 drives the conveying belt 3 to rotate and moves the workpiece to the pressing roller 10. One end of the workpiece passes through the lower end of the pressing roller 10. At the same time, the second motor 17 drives the two conveying rollers 9 to rotate and pull out the film. At the same time, the electromagnet 19 is electrified and exerts an attractive force on the magnet 20. The pressing roller 10 moves downward and presses one end of the film on the surface of the workpiece. The spring expansion rod 11 is compressed. The workpiece continues to move, and the film is continuously pulled out. The pressing roller 10 always exerts pressure on the film. When the workpiece completely passes through the pressing roller 10, the pressing roller 10 no longer presses on the workpiece, and the cutter 12 moves towards the workpiece. The cutter 12 presses the film on the workpiece and cuts off the film. At the same time, the second motor 17 stops, and the film is no longer pulled out. Then the electromagnet 19 is de-energized, and the spring expansion rod 11 drives the pressing roller 10 and the cutter 12 to reset. The conveying belt 3 drives the subsequent workpiece to move to the pressing roller 10 and repeats the film pasting work.

[0037] The device can automatically pull out the film and cut off the film. During the film pasting process, the pressing roller 10 exerts pressure on the film, so that the film is tightly attached to the surface of the workpiece, thereby improving the film pasting efficiency and quality.

[0038] Two strip-shaped limiting rods 21 are fixedly installed on the support 6 and are spaced apart. The two strip-shaped limiting rods 21 limit the two sides of the workpiece. When the workpiece moves on the conveying belt 3, the two strip-shaped limiting rods 21 can prevent the workpiece from deviating.

[0039] Working principle: The first motor 4, the second motor 17 and the electromagnet 19 are electrically connected with the controller 5. The controller 5 can control the working of the first motor 4, the second motor 17 and the electromagnet 19.

[0040] Before the film pasting work starts, the film is pulled to the lower end of the lower pressing roller 10, and the plate-shaped workpiece 101 is placed on the conveying belt 3, and the controller 5 controls the first motor 4 to work, and the first motor 4 drives the belt roller 2 to rotate, and the conveying belt 3 is driven to run and convey the plate-shaped workpiece 101 on it.

[0041] The first motor 4 drives the conveying belt 3 to run and moves the workpiece to the lower pressing roller 10, and when one end of the workpiece passes through the lower end of the lower pressing roller 10, the controller 5 controls the second motor 17 to work,

[0042] At the same time, the second motor 17 drives the two conveying rollers 9 to rotate and pull out the film, and at the same time, the controller 5 controls the electromagnet 19 to be electrified, and the electromagnet 19 is electrified and exerts an attractive force on the magnet 20, the lower pressing roller 10 moves downward and presses one end of the film on the surface of the workpiece, and the spring telescopic rod 11 is compressed. The workpiece continues to move, the film is continuously pulled out, and the lower pressing roller 10 always exerts pressure on the film. When the workpiece completely passes through the lower pressing roller 10, the lower pressing roller 10 no longer presses on the workpiece, and the cutter 12 moves towards the workpiece, and the cutter 12 presses the film on the workpiece and cuts off the film. At the same time, the controller 5 controls the second motor 17 to stop, and the film is no longer pulled out. Then the controller 5 controls the electromagnet 19 to be de-energized, and the spring telescopic rod 11 drives the lower pressing roller 10 and the cutter 12 to reset by the elastic force. The conveying belt 3 drives the subsequent workpiece to move to the lower pressing roller 10 and repeats the film pasting work.

[0043] After the film pasting is completed, the workpiece is driven by the conveying belt 3 to the image detection device 13, and the workpiece is driven to pass through the image detection device 13, and the image detection device 13 takes pictures of the workpiece and converts them into image signals, which are then transmitted to a dedicated image processing system. According to the pixel distribution, brightness, color and other information, the image processing system converts these image signals into digital signals and performs various operations to extract the characteristics of the target. Finally, according to the preset film pasting state, the image processing system outputs the results, and outputs the qualified or unqualified results.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features.
