[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Please also read Figures 1 to 7, the roll-to-roll flexible circuit board winding and deflection correction device of the present invention is described. A roll-to-roll flexible circuit board winding and deflection correction device includes a winding unit 10 and a deflection correction unit 20, the winding unit 10 has a lower frame 101, an upper frame 102 located above the lower frame 101, a winding part rotatably connected to the upper frame 102, and a driving member connected to the winding part in a transmission manner, the upper frame 102 is slidably connected to the lower frame 101 in the horizontal direction, and the rotating axis of the winding part is parallel to the sliding direction of the upper frame 102; the deflection correction unit 20 has a first telescopic member 201 fixedly arranged between the upper frame 102 and the lower frame 101 and a first sensor for monitoring the edge position of the coil, the movable end of the first telescopic member 201 is fixedly connected to the upper frame 102, the length of the first telescopic member 201 is adjustable in the horizontal direction, and the first telescopic member 201 is communicatively connected to the first sensor.

[0020] The first sensor monitors the edge position of the coil in real time to obtain the actual position. The first sensor presets a standard position. When the actual position does not coincide with the standard position, the first telescopic member 201 drives the upper frame 102 to move from the standard position to the actual position.

[0021] Specifically, a notch 1011 is provided on the top surface of the lower frame 101, and guide rails 1021 are provided on the front and rear sides of the notch 1011. The two guide rails 1021 are fixedly connected to the top surface of the lower frame 101, and a plurality of slide seats 1012 slidably adapted to the guide rails 1021 are fixedly provided on the bottom wall of the upper frame 102; the first telescopic member 201 is fixedly connected in the lower frame 101, and a connecting member 1022 is fixedly provided between the first telescopic member 201 and the bottom wall of the upper frame 102 at the notch 1011.

[0022] It should be noted that the first sensor is an ultrasonic sensor, and the first telescopic member 201 can be a telescopic oil cylinder, a hydraulic cylinder, or an electric cylinder.

[0023] Compared with the prior art, the roll-to-roll flexible circuit board winding and deviation correction device provided in this embodiment has the following advantages: The first sensor monitors the edge position of the coil in real time. If there is a deviation between the actual position of the edge of the coil and the preset position, the first sensor transmits a start signal to the first telescopic member 201. After receiving the start signal, the first telescopic member 201 drives the upper frame 102 to move from the standard position to the actual position, so that the winding part moves from the standard position to the actual position; thereby, when the winding part is winding the coil, the position of the air inflation shaft 103 can be adjusted according to the position of the coil, and the deviation of the coil can be compensated by the movement of the winding part.

[0024] In some embodiments, see Figure 1 and Figure 2The winding unit 10 also includes an air-expanding shaft 103 and an inflatable member. The air-expanding shaft 103 forms a winding portion. An air cavity is provided inside the air-expanding shaft 103. The outer wall of the air-expanding shaft 103 is provided with a plurality of through grooves 1031 connected to the air cavity. A key strip 1032 is radially slidably connected to the air-expanding shaft 103 in the through groove 1031. The inflatable member is connected to the air cavity.

[0025] After the inflatable member inflates the air cavity, the gas inflated into the air cavity squeezes the key strip 1032 out of the through slot 1031 .

[0026] Specifically, the inflatable member may be an air pump.

[0027] The key bar 1032 is squeezed by the gas and extends out of the through slot 1031 to press against the inner wall of the coil, so that the coil and the air expansion shaft 103 do not move relative to each other, thereby ensuring the stability of the coil during the winding process.

[0028] In some embodiments, see Figure 2 and Figure 4 A second sensor is provided on the air-inflating shaft 103, and the second sensor is used to monitor the weight of the coiled material on the air-inflating shaft 103; the winding unit 10 also includes a pressure controller connected to the second sensor for communication, and the pressure controller is used to adjust the pressure in the air cavity; the greater the weight of the coiled material on the air-inflating shaft 103, the greater the pressure in the air cavity.

[0029] Specifically, the second sensor is a weight sensor.

[0030] The weight of the coil increases with the progress of winding. After the weight sensor detects the increase in the weight of the coil, the weight sensor transmits an adjustment signal to the pressure controller, allowing more gas to enter the air cavity, increasing the pressure in the air cavity, thereby increasing the pressing force of the key strip 1032 on the coil, thereby ensuring the stability of the coil when the weight of the coil increases.

[0031] In some embodiments, see Figure 1 A guide roller 1023 is detachably connected to the bottom of the upper frame 102. The axial direction of the guide roller 1023 is parallel to the axial direction of the gas expansion shaft 103 and is located on the front side of the gas expansion shaft 103. A horizontally placed bracket 1024 is spaced apart on one side of the guide roller 1023. The bracket 1024 is fixedly connected to the upper frame 102, and the first sensor is detachably connected to the bracket 1024.

[0032] Specifically, the air shaft 103 is disposed on the top of the upper frame 102. The first sensor is detachable from the bracket 1024, and the position of the first sensor can be adjusted according to the width of the coil, thereby improving the application range of the deviation correction device.

[0033] The guide roller 1023 is provided to ensure that the coil sensed by the first sensor is always flat, thereby improving the accuracy of the deviation correction. If the span of the coil is too large or slightly uneven, the deviation correction action will be affected.

[0034] In some embodiments, see Figure 1 The roll-to-roll flexible circuit board winding and correcting device also includes a plurality of stabilizing units 30 arranged on the bottom wall of the lower frame 101 , and the stabilizing units 30 include adsorption portions fixedly connected to the bottom wall of the lower frame 101 .

[0035] In some embodiments, see Figure 6 The stabilizing unit 30 further includes an adsorption block 301 and a piston plate 302 . The adsorption block 301 forms an adsorption portion. The adsorption block 301 has an operating chamber 3011 . The piston plate 302 is slidably connected in the operating chamber 3011 along a vertical direction.

[0036] The roll-to-roll flexible circuit board winding and correcting device further includes a power unit 40 , which has a first transmission assembly extending into the operating cavity 3011 , and the first transmission assembly is used to drive the piston plate 302 to slide.

[0037] The piston plate 302, the ground and the adsorption block 301 form a closed space. When the first transmission assembly drives the piston plate 302 to slide upward, the pressure in the closed space decreases, so that the adsorption block 301 is adsorbed and fixed to the ground; conversely, when the first transmission assembly drives the piston plate 302 to slide downward, the adsorption block 301 is separated from the ground.

[0038] In some embodiments, see Figure 6 The first transmission assembly includes a second telescopic member 401, a transmission roller and a transmission seat 405. The second telescopic member 401 is fixedly arranged on the inner wall of the operating chamber 3011; the transmission seat 405 is fixedly connected to the bottom end of the second telescopic member 401, and the transmission seat 405 is provided with a transmission chamber 4051 which passes through from top to bottom, and the inner wall of the transmission chamber 4051 has a spiral transmission groove 4052; the transmission roller passes through the transmission chamber 4051, and a transmission block 4031 is fixedly arranged on the outer wall of the transmission roller. The transmission roller is screwed to the piston plate 302, and a transmission block 4031 which cooperates with the transmission groove 4052 is fixedly arranged on the outer wall of the transmission roller.

[0039] Specifically, the second telescopic member 401 may be a telescopic oil cylinder, an electric cylinder, or a hydraulic cylinder.

[0040] The second telescopic member 401 extends downward to drive the transmission seat 405 to move downward. During the downward movement of the transmission seat 405, the transmission block 4031 slides in the transmission groove 4052, thereby causing the transmission roller to rotate. Since the transmission roller and the piston plate 302 are screwed, and the piston plate 302 is slidably connected in the operating chamber 3011 along the vertical direction, the piston plate 302 moves upward at this time; conversely, when the second telescopic member 401 is retracted upward to drive the transmission seat 405 to move upward, the piston plate 302 moves downward.

[0041] In some embodiments, see Figure 6 and Figure 7 The bottom wall of the adsorption block 301 is provided with an annular groove 3012, and the annular groove 3012 is arranged at intervals on the outer periphery of the operating cavity 3011. A sealing ring 3013 is slidably connected in the annular groove 3012 along the vertical direction; the power unit 40 also includes a second transmission assembly, and the second transmission assembly is used to drive the sealing ring 3013 to move downward and press against the ground.

[0042] The sealing ring 3013 is moved downward and pressed against the ground through the second transmission assembly, thereby reducing the possibility of a gap between the adsorption block 301 and the ground and improving the airtightness between the adsorption block 301 and the ground.

[0043] In some embodiments, see Figure 6 A linkage chamber 3014 connected between the annular groove 3012 and the operating chamber 3011 is provided in the adsorption block 301. The transmission roller has a light rod 402, a transmission rod 403 and a threaded rod 404 arranged in sequence from top to bottom. The transmission block 4031 is arranged on the transmission rod 403, and the threaded rod 404 is screwed to the piston plate 302.

[0044] The second transmission assembly includes an extrusion ring 406, an extrusion rod 407 and a first elastic member 408. The extrusion ring 406 is arranged on the outer periphery of the transmission seat 405. There are multiple extrusion rods 407. One end of the extrusion rod 407 is fixedly connected to the extrusion ring 406, and the other end passes through the linkage cavity 3014 and is fixedly connected to the sealing ring 3013. The extrusion rod 407 is slidably connected to the adsorption block 301 along the vertical direction. There are multiple first elastic members 408, which are fixedly arranged between the transmission seat 405 and the extrusion ring 406.

[0045] Among them, the second telescopic member 401 extends downward to drive the transmission seat 405 to move downward. At this time, the elastic force of the first elastic member 408 is not overcome, and the transmission seat 405 makes the sealing ring 3013 press against the ground through the extrusion ring 406 and the extrusion rod 407. At the same time, the transmission block 4031 begins to enter the bottom end of the transmission groove 4052; the second telescopic member 401 continues to extend to drive the transmission seat 405 to move downward. At this time, the elastic force of the first elastic member 408 has been overcome, and the extrusion ring 406 moves upward. At this time, the first elastic member 408 has a pre-tightening force for the extrusion ring 406 to move downward.

[0046] Specifically, a first reset plate 4053 is fixedly provided at the end of the extrusion rod 407 located in the operating cavity 3011, a second reset plate 3015 is fixedly provided on the inner wall of the operating cavity 3011, and a second elastic member 501 is fixedly provided between the first reset plate 4053 and the second reset plate 3015. The second elastic member 501 has a pre-tightening force that causes the extrusion rod 407 to move upward.

[0047] Specifically, a guide rod 50 is fixedly disposed on the top surface of the first reset plate 4053 , and the guide rod 50 is arranged in the vertical direction. The top end of the guide rod 50 passes through the second reset plate 3015 and the two are slidably adapted. The second elastic member 501 is spirally disposed on the outer periphery of the guide rod 50 .

[0048] It should be noted that the first elastic member 408 is a telescopic rod with a spring, the telescopic rod has a multi-stage telescopic structure, and the second elastic member 501 is a spring.

[0049] The second telescopic member 401 extends downward to drive the transmission seat 405 to move downward. The transmission seat 405 first moves downward along the light rod 402. During the process of the transmission seat 405 moving downward along the light rod 402, the elastic force of the first elastic member 408 is not overcome, and there is no relative movement between the extrusion rod 407 and the fixing ring, so that the extrusion rod 407 drives the sealing ring 3013 to move downward and press against the ground; after the sealing ring 3013 presses against the ground, the transmission seat 405 starts to move downward along the transmission rod 403. At this time, the transmission block 408 is 031 begins to enter the bottom end of the transmission groove 4052; the second telescopic member 401 continues to extend downward to continue to drive the transmission seat 405 to move downward. During the downward movement of the transmission seat 405 along the transmission rod 403, the elastic force of the first elastic member 408 has been overcome, and the extrusion rod 407 moves upward relative to the fixed ring, and the sealing ring 3013 continues to be pressed against the ground. At the same time, the transmission block 4031 slides along the transmission groove 4052 to rotate the transmission roller, thereby causing the threaded rod 404 to move the piston plate 302 upward during the rotation.

[0050] The second telescopic member 401 is retracted upward to drive the transmission seat 405 to move upward, and the transmission seat 405 first moves upward along the transmission rod 403. During the process of the transmission seat 405 moving upward along the transmission rod 403, the first elastic member 408 releases the elastic force to make the extrusion ring 406 move downward until it is reset. At the same time, the transmission block 4031 slides along the transmission groove 4052 to make the transmission roller rotate, so that the threaded rod 404 rotates to make the piston plate 302 move downward until it is reset; after the piston plate 302 is reset, the transmission seat 405 begins to move upward along the light rod 402, and at this time the transmission block 4031 disengages from the top of the transmission groove 4052; the second telescopic member 401 continues to be retracted upward to drive the transmission seat 405 to continue to move upward, and during the process of the transmission seat 405 moving upward along the light rod 402, the second elastic member 501 releases the elastic force to drive the extrusion rod 407 to move upward, so that the extrusion rod 407 drives the sealing ring 3013 upward until it is off the ground.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
