[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only one embodiment of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 9 , the present invention provides a flexible printed circuit board stripping mechanism. Among them, a plurality of neatly arranged flexible printed circuit boards 9 are installed on the plastic sheet 2. The plastic sheet 2 is a sheet material and is manually stacked and placed inside the tray 31 to achieve feeding and placement, and then automatically enters the stripping mechanism to strip, take out and transfer the flexible printed circuit boards 9.

[0032] Such as Figure 1As shown, the peeling mechanism includes a frame 1, which consists of two parts, an upper part and a bottom part; a placement plate 4 is installed on the frame 1. The placement plate 4 is used to place two plastic sheets 2, facilitating subsequent ultrasonic welding to connect them together to form a strip or a band; the left side of the placement plate 4 is the feeding side of the plastic sheet 2, and the right side is the peeling side of the flexible printed circuit board 9. Specifically, a suction cup assembly 3 for adsorbing the plastic sheet 2 is installed on the left side of the placement plate 4. The suction cup assembly 3 and the plastic sheet 2 move horizontally under the drive of the moving assembly 32 to place the plastic sheet 2 on the placement plate 4. A peeling plate 7 is installed on the right side of the placement plate 4. The plastic sheet 2 is placed on the peeling plate 7 for peeling the flexible printed circuit board 9.

[0033] Furthermore, a welding assembly 6 for welding adjacent plastic sheets 2 is installed on the placement plate 4. The welding assembly 6 connects the sheet-shaped plastic sheets 2 into a strip or a band-shaped plastic sheet 2 in sequence, thus making it more convenient to realize the horizontal movement of the plastic sheet 2.

[0034] Even further, a multi-axis picking manipulator 8 is installed on one side of the peeling plate 7. The multi-axis picking manipulator 8 picks up the flexible printed circuit board 9 on the plastic sheet 2. A waste winding assembly 5 for winding the plastic sheet 2 is installed under the peeling plate 7.

[0035] As Figure 1 shown, in this embodiment, multiple modules are used to form the multi-axis picking manipulator 8, thereby reducing the manufacturing cost. Existing mature four-axis manipulators or six-axis manipulators can also be used; furthermore, as Figure 9 shown, a number of vacuum adsorption holes 81 for vacuum-adsorbing the flexible printed circuit board 9 are provided at the end of the multi-axis picking manipulator 8.

[0036] As Figure 3 shown, a tray 31 for placing the plastic sheet 2 is installed under the suction cup assembly 3. Adjustable limit blocks are provided around the tray 31, so as to adapt to plastic sheets 2 of different specifications; as Figure 4As shown, the suction cup assembly 3 is drivingly connected to the moving assembly 32. The moving assembly 32 drives the suction cup assembly 3 and the plastic sheet 2 to move horizontally back and forth. In this embodiment, the moving assembly 32 includes a first motor 321 and a first lead screw 322 installed on the frame 1. The first lead screw 322 is located above the first motor 321. The first motor 321 drives the first lead screw 322 to rotate through a first synchronous belt 323. A first slider 324 is sleeved on the first lead screw 322. Driven by the first motor 321, the first slider 324 moves horizontally along the first lead screw 322. Among them, the first lead screw 322 can be an ordinary threaded lead screw or a ball screw with higher precision and less friction. The suction cup assembly 3 is installed on the first slider 324.

[0037] To further ensure the smoothness of the horizontal movement, in this embodiment, a horizontal guide rail is also installed on the frame 1. The first slider 324 is sleeved on the horizontal guide rail and moves horizontally along the horizontal guide rail.

[0038] As Figure 3 shown, the suction cup assembly 3 includes a first vertical driving member 331 installed on the first slider 324. A picking bracket 332 driven by the first vertical driving member 331 to move vertically is installed at the end of the first vertical driving member 331. The picking bracket 332 includes a horizontal picking bracket and a vertical picking bracket. The horizontal picking bracket and the vertical picking bracket are cuboids. A plurality of vacuum suction nozzles 333 arranged neatly are installed on the vertical picking bracket. The vacuum suction nozzles 333 use vacuum to adsorb and pick up the plastic sheet 2.

[0039] Both the horizontal picking bracket and the vertical picking bracket are provided with U-shaped grooves, so that the vacuum suction nozzles 333 can be adjusted horizontally and vertically. The number of the vacuum suction nozzles 333 is two. Using the vacuum suction nozzles 333 can better adsorb and pick up the plastic sheet 2.

[0040] The first vertical driving member 331 is used to pick up the plastic sheet 2 and move vertically back and forth. The first vertical driving member 331 can be a vertical driving module or a single multi-stage cylinder.

[0041] If a vertical driving module is used, its output can be stably controlled to achieve multi-stage output. If a single multi-stage cylinder is used, stable multi-stage output can also be achieved. If a single ordinary cylinder is used, when placing the plastic sheet 2, it is directly released for placement, with a certain distance, resulting in a large placement deviation and a low subsequent welding qualification rate.

[0042] However, in this embodiment, the first vertical driving member 331 includes a first vertical air cylinder and a second vertical air cylinder installed at the end of the first vertical air cylinder. The first vertical air cylinder and the second vertical air cylinder are spliced together to achieve multi-stage control.

[0043] Among them, the first vertical air cylinder is installed on the first slider 324; a picking bracket 332 is installed at the end of the second vertical air cylinder; further, during the picking process, the first vertical air cylinder drives the second vertical air cylinder and the vacuum suction nozzle 333 to move vertically downward to pick up the plastic sheet 2 and vertically return to the original position; during the process of placing the plastic sheet 2, the second vertical air cylinder moves vertically downward to vertically place the plastic sheet 2 on the placing plate 4 to achieve stable placement.

[0044] As Figure 5 shown, at least one pressing assembly 41 for pressing adjacent two plastic sheets 2 is installed on the upper part of the placing plate 4. After the plastic sheet 2 is placed, the pressing assembly 41 presses it to press and fix the end of the former and the front end of the latter, so as to facilitate subsequent ultrasonic welding.

[0045] As Figure 5 shown, the pressing assembly 41 includes a second vertical driving member 411 installed on the frame 1, a pressing plate 412 is installed at the end of the second vertical driving member 411, and the pressing plate 412 covers the entire plastic sheet 2, so as to facilitate pressing the plastic sheet 2; further, after the plastic sheet 2 is placed, the second vertical driving member 411 drives the pressing plate 412 to move downward to press and fix adjacent two plastic sheets 2.

[0046] As Figure 5 shown, the second vertical driving member 411 can adopt a vertical driving module, and its output can be stably controlled. However, in this embodiment, the second vertical driving member 411 adopts a third vertical air cylinder to achieve stable pressing at a fixed distance.

[0047] As Figure 5 shown, the welding assembly 6 includes a third vertical driving member 61 installed on the upper part of the placing plate 4 and an ultrasonic die head 62 installed on the lower part of the placing plate 4. A bottom film 63 is installed at the end of the third vertical driving member 61. In this embodiment, the third vertical driving member 61 adopts a fourth vertical air cylinder to achieve stable ultrasonic welding at a fixed distance.

[0048] The ultrasonic die head 62 is fixedly connected to the frame 1 through a support rod 64. Further, by adjusting the vertical position of the ultrasonic die head 62 on the support rod 64, the vertical height of the ultrasonic die head 62 is adjusted, so as to better cooperate with the bottom film 63 and better perform ultrasonic welding.

[0049] Further, since the pressing plate 412 is located below the bottom film 63, during ultrasonic welding, the bottom film 63 needs to pass through the pressing plate 412. Therefore, a number of avoidance holes 413 are provided on the pressing plate 412. The third vertical driving member 61 drives the bottom film 63 to move downward, pass through the avoidance holes 413, and cooperate with the ultrasonic die head 62 below to perform ultrasonic welding on two adjacent plastic sheets 2.

[0050] Further, as Figure 5 shown, the third vertical driving member 61 can adopt a vertical driving module, which can stably control its output. However, in this embodiment, the third vertical driving member 61 adopts a fourth vertical cylinder to achieve stable ultrasonic welding at a fixed distance.

[0051] Furthermore, after the vacuum nozzle 333 places the plastic sheet 2, the end of the previous plastic sheet 2 coincides with the front end of the next plastic sheet 2. The second vertical driving member 411 drives the pressing plate 412 to move downward to press and fix two adjacent plastic sheets 2, so that the two plastic sheets 2 are in a relatively stationary state; the third vertical driving member 61 drives the bottom film 63 to move downward, pass through the avoidance holes 413, and cooperate with the ultrasonic die head 62 below to perform ultrasonic welding on two adjacent plastic sheets 2. Thus, the splicing and welding of two adjacent plastic sheets 2 are completed, enabling the subsequent sheet materials to form a continuous moving process.

[0052] As Figure 6 shown, after ultrasonic welding of two adjacent plastic sheets 2, the welding area needs to be flattened to reduce burrs and friction. A flattening assembly 42 for flattening the connection between two adjacent plastic sheets 2 is installed between the placement plate 4 and the peeling plate 7; the flattening assembly 42 includes a fourth vertical driving member 421 installed on the frame 1, and a rolling wheel 422 is installed at the end of the fourth vertical driving member 421. The fourth vertical driving member 421 drives the rolling wheel 422 to move downward to roll and flatten the connection between two adjacent plastic sheets 2. In this embodiment, the fourth vertical driving member 421 adopts a fifth vertical cylinder to achieve stable rolling and flattening at a fixed distance.

[0053] As Figure 6As shown, in order to stop the plastic sheet 2 so that the multi-axis picking manipulator 8 is convenient for picking and is also convenient for welding two adjacent plastic sheets 2, at some necessary moments, it is necessary to stop the plastic sheet 2 and fix it at a certain position. A first stopping component 43 for stopping the plastic sheet 2 is further installed on the rolling wheel 422. Specifically, the first stopping component 43 includes fifth vertical driving members 431 installed on both sides of the rolling wheel 422. The fifth vertical driving members 431 drive the rolling wheel 422 to move downward to press the laterally moving plastic sheet 2 to stop its movement. In this embodiment, the fifth vertical driving members 431 adopt sixth vertical cylinders to realize the vertical downward movement of the rolling wheel 422.

[0054] In some embodiments, it can be directly and slowly driven by the waste winding component 5. During ultrasonic welding, its driving can be controlled to stop, so that ultrasonic welding can be stabilized; or during the picking by the multi-axis picking manipulator 8, its driving can be controlled to stop, so that picking can be stabilized.

[0055] Furthermore, a first stopping component 43 can also be added to ensure that the plastic sheet 2 is not easily moved during welding; improve the accuracy after welding, and ensure the subsequent picking accuracy.

[0056] Furthermore, in order to further improve the picking accuracy and the movement accuracy of the lateral movement of the plastic sheet 2, the stripping plate 7 is also drivingly connected with a lateral driving component 71. The lateral driving component 71 drives the stripping plate 7 and the plastic sheet 2 to move laterally; the lateral driving component 71 includes a second motor 711 installed on the machine frame 1, a second synchronous belt 712 installed at the end of the second motor 711, and a sliding block 713 installed on the second synchronous belt 712. The sliding block 713 is fixedly connected with the stripping plate 7. The second motor 711 drives the stripping plate 7 and the plastic sheet 2 to move laterally through the second synchronous belt 712 and the sliding block 713; the stripping plate 7 moves in a reciprocating linear motion, and also drives the plastic sheet 2 to move intermittently laterally. Its stopping performance is excellent, and it can feed multiple times row by row. When picking in the same row, it remains stationary, improving the picking accuracy and consistency.

[0057] The second motor 711 outputs a rotational motion outward, and converts the rotational motion into the lateral movement of the second synchronous belt 712 through the second synchronous belt 712 and the synchronous wheel matching with the second synchronous belt 712 to realize the lateral movement of the sliding block 713 and the stripping plate 7.

[0058] As Figure 8As shown, the waste winding assembly 5 includes a third motor 51 installed on the frame 1 and a winding drum 52 drivingly connected to the third motor 51. In this embodiment, the third motor 51 is installed on the frame 1 and is located below the winding drum 52. The third motor 51 drives the winding drum 52 to rotate through a synchronous pulley and a synchronous belt, winds the plastic sheet 2, and can also drive the plastic sheet 2 horizontally.

[0059] As Figure 7 and Figure 8 shown, in order to drive the plastic sheet 2 to move horizontally and wind the plastic sheet 2, a middle driving assembly 53 is further installed between the peeling plate 7 and the waste winding assembly 5. The middle driving assembly 53 includes a fourth motor 531 installed on the frame 1 and a middle drum 532 drivingly connected to the fourth motor 531. The fourth motor 531 drives the middle drum 532 to wind and drive the plastic sheet 2.

[0060] As Figure 7 and Figure 8 shown, a second stopping assembly 54 for stopping the winding of the plastic sheet 2 is installed below the middle driving assembly 53. The second stopping assembly 54 includes a stopping drum 541 installed below the middle drum 532 and sixth vertical driving members 542 installed on both sides of the stopping drum 541. The sixth vertical driving members 542 drive the stopping drum 541 to move upward, press the wound plastic sheet 2, and make it stop moving. The sixth vertical driving members 542 adopt seventh vertical cylinders to realize the vertical upward movement of the stopping drum 541; the stopping drum 541 cooperates with the middle drum 532 to clamp the plastic sheet 2, so that the plastic sheet 2 stops moving, and the plastic sheet 2 will not be wound or reverse unwound, creating conditions for the horizontal movement of the peeling plate 7, and realizing the stable horizontal feeding and stable horizontal movement of the plastic sheet 2.

[0061] The present utility model further installs a lamp board inside the peeling plate 7. The lamp board emits light outward to irradiate the plastic sheet 2 and the flexible circuit board 9 on the peeling plate 7, facilitating the shooting by the camera 74 above the peeling plate 7. The camera 74 shoots the flexible circuit board 9 on the plastic sheet 2. The plastic sheet 2 is a transparent component, and the flexible circuit board 9 is an opaque component. When irradiated by the lamp board, the flexible circuit board 9 is in a shadow part, facilitating the shooting and positioning by the camera 74, so as to control the picking of the multi-axis picking manipulator 8.
