[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0051] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0053] The general product bonding process requires manual cutting of the coils, and then manual transport of the sheets and the cut coils to the existing bonding machine, which also requires manual positioning and installation before bonding. Workers need to carry and load and unload the coils multiple times, which is labor-intensive and has low production efficiency.

[0054] The present invention provides a feeding system 100, which is applied to a laminating machine.

[0055] Reference Figure 1 to Figure 2 In the embodiment of the present invention, the feeding system 100 includes a frame 10, a feeding assembly 20, a correction assembly 30, a label tracking assembly 60 and a driving assembly 40. The feeding assembly 20 includes a reel 21 and a material pulling member 23. The reel 21 is rotatably connected to the frame 10 and is used to release the coil. The material pulling member 23 is installed on the frame 10 and is used to pull the coil. The correction assembly 30 includes a sensor 31 and a correction device 33 installed on the frame 10. The sensor 31 is located between the reel 21 and the material pulling member 23. The sensor 31 is fixedly connected to the correction device 33. The sensor 31 is used to detect the deviation of the coil. The correction device 33 is located between the reel 21 and the sensor 31. The correction device 33 is wound around the coil. The correction device 33 is connected to the sensor 31 by signal. The correction device 33 corrects the width direction of the coil according to the feedback information of the sensor 31. The tracking component 60 is installed on the frame 10. The tracking component 60 is located between the sensor 31 and the material pulling member 23 and above the coil. The tracking component 60 is used to control the conveying length of the coil. The driving component 40 is installed on the frame 10. The driving component 40 drives the material pulling member 23 to rotate to drive the coil to move.

[0056] Furthermore, the feeding system 100 is provided with a feeding station, a deviation correction station and a measuring station from bottom to top, the unwinding roller 21 is located at the feeding station, and the material pulling member 23 is located at the detection station. With such an arrangement, compared with the stations designed horizontally, that is, the stations arranged from left to right, the present invention can make the internal components of the entire feeding system 100 more compact, thereby effectively reducing the volume of the feeding device. The unwinding roller 21 can wind a large amount of coils to store the coils, and serve as the coil supply source for the entire feeding system 100, thereby effectively reducing the number of times workers carry and install the coils, and improving production efficiency. The material pulling member 23 serves as the output end of the entire feeding system 100, and drives the coils to move on the feeding system 100, thereby achieving a stable supply of coils and improving production efficiency.

[0057] The deflection corrector 33 is located at the deflection correcting station, and the sensor 31 is located between the deflection correcting station and the detection station. The sensor 31 detects the offset in the width direction of the coil, and then feeds back the information to the deflection corrector 33. The deflection corrector 33 automatically corrects the position in the width direction of the coil according to the information, thereby effectively reducing the feeding deviation of the entire feeding system 100, ensuring accurate and stable feeding, thereby effectively avoiding the deviation of the coil position during coil processing, and further effectively reducing the defective rate of the product. In particular, for the production of circuit boards, such as: the bonding of FPC (flexible circuit board) and reinforcement plate, etc., higher precision is required. The present invention can pre-correct the position deviation of the coil from the source of coil feeding, provide accurate coil processing position, and solve the problem of high product defective rate due to position deviation in high-precision processing. In addition, the sensor 31 is fixedly connected to the deflection corrector 33, that is, the sensor 31 is adjacent to the deflection corrector 33, and the coil output from the deflection corrector 33 can be immediately detected by the sensor 31 to see if there is any deviation, that is, real-time deflection correction can be achieved, which can effectively improve the efficiency of deflection correction of the coil, thereby reducing the impact of the deviation of the coil, and thereby reducing the defective rate of the coil product.

[0058] The tracking component 60 is located at the measuring station and detects the coil delivery length to accurately control the coil feeding length and ensure accurate and stable feeding, thereby effectively avoiding the deviation of the coil length during coil processing, and further effectively reducing the defective rate of the product.

[0059] The driving assembly 40 drives the material pulling member 23 to move, so as to drive the coil to move. The driving assembly 40 is electrically connected to the tracking assembly 60, and the tracking assembly 60 controls the movement of the driving assembly 40 to accurately control the feeding length of the coil, so that the entire feeding system 100 has a high degree of automation, thereby effectively improving production efficiency.

[0060] The correction component 30 and the tracking component 60 work together to accurately control the displacement of the output coil in the width and length directions, that is, the position and length of the output coil can be accurately controlled, so that the coil output each time is in the same position and length, that is, the coil output each time can be standardized, ensuring accurate and stable feeding, and thus effectively reducing the defective rate of products.

[0061] In addition, it should be noted that the sensor 31 can be a photoelectric sensor 31 , an ultrasonic sensor 31 , or other sensors 31 .

[0062] The deviation corrector 33 may be a servo motor driven guide roller deflection to adjust the running direction of the coil to the correct route, or a cylinder driven guide roller deflection to adjust the running direction of the coil to the correct route, or other effective methods of achieving coil deviation correction may be used.

[0063] The driving assembly 40 may be driven by a motor to rotate and thereby drive the coil to move, or may be driven by a cylinder to pull the coil to move, or may be driven by other effective driving methods.

[0064] Reference Figure 3 and Figure 5 In one embodiment of the present invention, the deflection corrector 33 includes a driving member 331, a tray 333 and two adjusting rollers 335. The driving member 331 is fixedly connected to the frame 10. A sensor 31 is installed on one side of the driving member 331, and the driving member 331 is signal-connected to the sensor 31. The tray 333 is installed above the driving member 331. The two adjusting rollers 335 are arranged side by side and are rotatably connected to the side of the tray 333 away from the driving member 331. The driving member 331 selectively drives the tray 333 to move relative to the frame 10 according to the feedback information of the sensor 31, and drives the two adjusting rollers 335 to move along the width direction of the coil to correct the deflection of the coil.

[0065] Furthermore, the two adjusting rollers 335 are arranged at intervals and are respectively connected to the tray 333 in rotation. The tray 333 is driven by the driving member 331 to move along the width direction of the coil, so that the position of the coil conveyed on the two adjusting rollers 335 in the width direction can be changed, thereby realizing the correction of the coil. The tray 333 can make the two adjusting rollers 335 move synchronously, so that the coil wound on the two adjusting rollers 335 can be adjusted synchronously, thereby reducing the error tolerance of the correction device 33, thereby improving the accuracy of the correction device 33. Moreover, such a structure is simple and easy to manufacture, which can effectively save the manufacturing cost of the feeding system 100. The two adjusting rollers 335 are arranged to drive the coil to move along the width direction, which is to drive the coil to move along the length direction at the same time. Compared with only one adjusting roller 335, the length of the coil driven by the two adjusting rollers 335 is longer, so the area of ​​the coil driven is larger, thereby effectively avoiding slipping between the adjusting rollers 335 and the coil, making the correction of the coil more stable and reliable.

[0066] In addition, it should be noted that the driving member 331 can be a servo motor, a cylinder, or other drivers.

[0067] Reference Figure 1 and Figure 3 In one embodiment of the present invention, the sensor 31 is located on one side of the coil along the length direction, and the sensor 31 detects the offset of the side of the coil. Compared with the offset obtained by detecting the plane of the coil, the sensor 31 detects the side of the coil, which makes it easier for the sensor 31 to capture the offset of the position in the width direction of the coil, and is more accurate and reliable, so that the offset of the coil along the width direction can be accurately obtained, and the structure is simple and easy to install.

[0068] Reference Figures 1 to 3 In one embodiment of the present invention, the tracking component 60 includes a telescopic member 63, a moving member 61 and a tracking member 65. The telescopic member 63 has a fixed end and a telescopic end. The fixed end is slidably connected to the frame 10 along the length direction of the coil, and the telescopic end moves toward or away from the fixed end along the width direction of the coil. The moving member 61 is fixedly connected to the frame 10, and the moving member 61 drives the telescopic member 63 to slide back and forth along the length direction of the coil; the tracking member 65 is fixedly connected to the fixed end of the telescopic member 63, and the tracking member 65 is disposed between the material pulling member 23 and the sensor 31, and is located above the coil. The tracking member 65 is used to detect the conveying length of the coil and feed it back to the laminating machine.

[0069] With such a configuration, the position of the label tracking member 65 can be automatically controlled, that is, the position of the label tracking member 65 for detecting the coil can be automatically controlled. Compared with manual adjustment, the position of the label tracking member 65 can be accurately adjusted, and it is fast and effective, thereby shortening the adjustment time, and further improving production efficiency. In addition, because the label tracking member 65 is jointly driven by the telescopic member 63 and the movable member 61, the label tracking member 65 can be positioned at any point in the width direction and the length direction of the coil, that is, the label tracking member 65 can be positioned at any point on the plane of the coil, thereby meeting the needs of different coils for different detection positions, thereby improving the applicability of the feeding system 100.

[0070] In addition, it should be noted that the moving member 61 may be driven by a motor to drive a screw rod to move the telescopic member 63 , or by a cylinder to drive the telescopic member 63 to move, or by other effective driving methods to drive the telescopic member 63 to move.

[0071] The moving part 61 includes a slide rail, a motor and a screw rod. The measuring station of the frame 10 is provided with the slide rail in the conveying direction of the coil. The telescopic part 63 is installed on the slide rail and can slide back and forth along the slide rail. The motor is fixedly connected to the frame 10. The motor and the telescopic part 63 are connected through a screw rod. A threaded hole is provided on the telescopic part 63. The threaded section of the screw rod is inserted into the threaded hole of the telescopic part 63, and the threads are matched. The motor drives the screw rod to rotate, and the thread of the screw rod pushes the telescopic part 63 to move along the slide rail. The telescopic part 63 can drive the tracking part 65 to extend and retract. The moving distance of the tracking part 65 can be accurately controlled by the thread of the screw rod, and the structure is simple, stable and reliable.

[0072] Reference Figures 1 to 3 In one embodiment of the present invention, the material pulling member 23 includes a first clamping roller 231 and a second clamping roller 233, and the first clamping roller 231 is rotatably connected to the frame 10. The second clamping roller 233 is rotatably connected to the frame 10, and the second clamping roller 233 is located below the first clamping roller 231. The coil is clamped between the first clamping roller 231 and the second clamping roller 233. The first clamping roller 231 and the second clamping roller 233 clamp the coil, and the driving assembly 40 drives the second clamping roller 233 to rotate, and the first clamping roller 231 and the second clamping roller 233 rotate synchronously. In the process of driving the coil to move, the coil will not wrinkle, and the coil is kept straight for transportation.

[0073] Reference Figures 1 to 3In one embodiment of the present invention, the feeding system 100 further comprises a film tearing assembly 50 mounted on the frame 10, the film tearing assembly 50 comprises a film tearing member 51 and a collecting roller 53, the film tearing member 51 comprises a third clamping roller 511 and a fourth clamping roller 513, the third clamping roller 511 is rotatably connected to the frame 10, the fourth clamping roller 513 is rotatably connected to the frame 10, the third clamping roller 511 is located above the fourth clamping roller 513, a protective film of the coil is sandwiched between the third clamping roller 511 and the fourth clamping roller 513, the third clamping roller 511 and the fourth clamping roller 513 clamp the coil, the driving assembly 40 drives the third clamping roller 511 to rotate, and drives the protective film of the coil to move. The collecting roller 53 is rotatably connected to the frame 10, the collecting roller 53 is used to wind the protective film of the coil, and the driving assembly 40 drives the collecting roller 53 to rotate to recover the protective film of the coil.

[0074] Some rolls have protective films, such as FPC (flexible printed circuit board). Usually, the film is torn off manually or by machine, and then manually transported to the laminating machine for lamination. This is not only inefficient, but also the rolls with the film torn off are easily contaminated during transportation, which leads to an increase in the defective rate of the product.

[0075] The feeding system 100 of the present invention tears the film at the output end of the coil, and the coil can enter the next process after the film is torn, without manual handling, thereby effectively improving production efficiency and effectively avoiding the contamination of the torn coil, thereby effectively reducing the defective rate of the product. In addition, by driving the protective film of the coil to move through two clamping rollers, the protective film of the coil will not wrinkle, and the protective film of the coil can be kept straight for transportation.

[0076] Reference Figure 1 , Figure 2 as well as Figure 4 In one embodiment of the present invention, the driving assembly 40 includes a first motor 41, a second motor 43 and a third motor 45. The first motor 41 is fixedly connected to the frame 10, the first motor 41 is rotationally matched with the second clamping roller 233, and the first motor 41 is rotationally matched with the third clamping roller 511, so that the second clamping roller 233 and the third clamping roller 511 rotate synchronously, and the first motor 41 is signal-connected with the sensor 31. The second motor 43 is fixedly connected to the frame 10, the second motor 43 is rotationally matched with the unwinding roller 21, and the second motor 43 is signal-connected with the sensor 31. The third motor 45 is fixedly connected to the frame 10, the third motor 45 is rotationally matched with the receiving roller 53, and the third motor 45 is signal-connected with the sensor 31.

[0077] By setting the first motor 41 to drive the second clamping roller 233 to rotate to pull the coil, and at the same time drive the third clamping roller 511 to rotate synchronously to pull the protective film of the coil, the coil and the protective film of the coil can move synchronously and maintain the same movement speed, thereby effectively avoiding the situation where the conveying speed of the coil is too fast to tear the film or the film tearing speed is too fast to complete the film tearing before the coil is conveyed to the corresponding position, so that the coil can be stably and reliably to complete the film tearing during the conveying process. The second motor 43 drives the unwinding roller 21 to release the coil, and the third motor 45 drives the collecting roller 53 to rotate to collect the protective film of the coil.

[0078] In addition, it should be noted that the first drive motor can realize the synchronous movement of the second clamping roller 233 and the third clamping roller 511 through gear transmission, or can realize the synchronous movement of the second clamping roller 233 and the third clamping roller 511 through belt transmission, or can be other transmission methods that realize the synchronous movement of the second clamping roller 233 and the third clamping roller 511.

[0079] Reference Figure 2 and Figure 3 In one embodiment of the present invention, the feeding system 100 further includes a plurality of supporting rollers 70, the coils pass around the supporting rollers 70, and the plurality of supporting rollers 70 are installed on the frame 10 from bottom to top and arranged along the conveying direction of the coils. The plurality of supporting rollers 70 can not only support the coils so that the coils are conveyed smoothly, but also the arrangement from bottom to top can effectively reduce the volume of the feeding system 100.

[0080] Reference Figures 1 to 5 In one embodiment of the present invention, the feeding system 100 further includes a dust removal roller 80, which is rotatably connected to the frame 10, and is located between the sensor 31 and the tracking assembly 60. The dust removal roller 80 presses the upper surface of the coil. The dust removal roller 80 can effectively remove dust or other contaminants adhering to the coil to ensure that the coil output by the coil supply device maintains a certain degree of cleanliness, thereby effectively reducing the defective rate of the product.

[0081] Reference Figure 1 and Figure 2In one embodiment of the present invention, both the unwinding roller 21 and the collecting roller 53 are air-expansion rollers. An air-expansion roller is a special roller, that is, a roller whose surface can protrude after being inflated with high pressure, and a roller whose surface part retracts rapidly after being deflated is called an air-expansion roller. As long as the air gun is pointed at the air nozzle on the air-expansion roller to inflate, the air can be held against the external parts (such as the coil). When the material needs to be released and unloaded, the air nozzle is pressed by hand to deflate, and the external parts (such as the coil) can be taken out. The setting of the unwinding roller 21 using the air-expansion roller can facilitate the installation of the coil, and the operation is simple and quick, thereby improving the efficiency of replacing the coil.
