[0072] With reference to Figure 3 , Figure 3 A flow chart of a flexible circuit board production exposure method provided by an embodiment of the present application, the flexible circuit board production exposure method of the embodiment of the present application can include but is not limited to including steps S310-S340.

[0074] Specifically, a first buffer roller for placing the coiled circuit board 300 is arranged outside the entrance of the flexible circuit board production exposure device, and a first motor is arranged on the first buffer roller. The first buffer roller can be rotated according to requirements, so as to uncoil the coiled circuit board 300. Similarly, a second buffer roller for placing the coiled circuit board 300 is arranged outside the exit of the flexible circuit board production exposure device, and a second motor is arranged on the second buffer roller.

After the coiled circuit board 300 enters the fixed module from the entrance of the flexible circuit board production exposure device, the flexible circuit board on the coiled circuit board 300 stops moving after the flexible circuit board is located in the exposure area. The coiled circuit board 300 is composed of a plurality of flexible circuit boards connected end to end, and can continuously enter the fixed module through the entrance of the flexible circuit board production exposure device, so that the flexible circuit boards on the coiled circuit board 300 are exposed in turn, and the exposure efficiency is high.

The offset of the coiled circuit board 300 is corrected by the corrector 280 according to the second offset, so as to correct the pose of the coiled circuit board 300, so that the deviation between the pose of the coiled circuit board 300 and the preset pose is within the preset range, that is, the offset of the coiled circuit board 300 after correction is within the preset range and can be ignored. By correcting the coiled circuit board 300, it is prevented that the wrinkles and skew of the coiled circuit board 300 cause corresponding wrinkles and skew of the coiled circuit board 300 after entering the fixed module, and further cause the exposure quality to be affected. It can be known that the second detection device 270 can be a video recognition device, which generates a corresponding second offset after processing the video or picture of the coiled circuit board 300 at the entrance by shooting and then transmitting to a corresponding processor. The second detection device 270 can be an infrared emission device, which generates a specific second offset by receiving infrared rays. The processor can be integrated in the second detection device 270, or can be arranged in the controller of the entire flexible circuit board production exposure equipment, which is not limited here.

Similarly, the second clamping device 266 also comprises a second clamping piece 267 movable up and down, and the second clamping piece 267 clamps the exposed circuit board after moving downward. The second clamping device 266 is arranged on the upper surface of the second support plate 265, and the lower surface of the second support plate 265 is fixedly connected with the second surface of the equipment frame 100 through the second support rod 264. The coiled circuit board 300 is clamped by the first clamping device 262 and the second clamping device 266 simultaneously, so that the Nth flexible circuit board on the coiled circuit board 300 is stabilized in the exposure area, where N is the serial number of the flexible circuit board, that is, the flexible circuit board on the coiled circuit board 300 is exposed according to the sequence. The tension detector is arranged in the exposure area, which can detect the surface tension of the flexible circuit board in the exposure area, so as to control the first clamping device 262 and the second clamping device 266 according to the tension, so that the flexible circuit board has a preset surface tension. Specifically, when the tension on the Nth flexible circuit board is greater than the preset tension, the first clamping device 262 is controlled to loosen the coiled circuit board 300, and the second clamping device 266 is controlled to clamp the coiled circuit board 300 (the coiled circuit board 300 clamped by the second clamping device 266 is the exposed circuit board after exposure). By controlling the second clamping device 266 to clamp the coiled circuit board 300 and the first clamping device 262 to loosen the coiled circuit board 300, the coiled circuit board 300 continues to enter the exposure area of the fixing module from the first clamping device 262, so as to reduce the surface tension of the flexible circuit board in the exposure area. Specifically, the first moving amount of the coiled circuit board 300 after continuing to move from the first clamping device 262 into the exposure area is determined according to the specific surface tension. The more the surface tension is, the more the first moving amount is. When the tension on the Nth flexible circuit board is less than the preset tension, the first clamping device 262 is controlled to clamp the coiled circuit board 300, and the second clamping device 266 is controlled to loosen the coiled circuit board 300 (the coiled circuit board 300 loosened by the second clamping device 266 is the exposed circuit board after exposure). By controlling the first clamping device 262 to clamp the coiled circuit board 300 and the second clamping device 266 to loosen the coiled circuit board 300, the coiled circuit board 300 continues to be pulled from the second clamping device 266, so as to increase the surface tension of the flexible circuit board in the exposure area. Specifically, the second moving amount of the coiled circuit board 300 after continuing to move from the second clamping device 266 to the outlet of the flexible circuit board production exposure equipment is determined according to the specific surface tension. The less the surface tension is, the more the second moving amount is.When the tension on the Nth flexible circuit board equals the preset tension, the first clamping device 262 is controlled to clamp the roll-up circuit board 300, and the second clamping device 266 is controlled to clamp the roll-up circuit board 300, so as to fix the position of the roll-up circuit board 300, so that the fixed pressing plate on the module presses the flexible circuit board in the exposure area.

[0079] In step S320, the fixing module is controlled to identify the positioning point of the roll-up circuit board 300, and sequentially fix the plurality of flexible circuit boards on the roll-up circuit board 300 in the exposure area according to the positioning point.

[0080] Specifically, the identification device arranged on the fixing module can identify the positioning point on the roll-up circuit board 300, so as to fix the flexible circuit board on the roll-up circuit board 300 in the exposure area. The head and tail of the specific flexible circuit board are both provided with positioning points, and the flexible circuit board is positioned in the exposure area by identifying the positioning points.

[0081] In an optional embodiment, the fixing module includes a fixing platform 290 and a fixed pressing plate, and the control of the fixing module to identify the positioning point of the roll-up circuit board 300 and sequentially fix the plurality of flexible circuit boards on the roll-up circuit board 300 in the exposure area according to the positioning point includes: controlling the fixing platform 290 to identify the positioning point of the roll-up circuit board 300; and controlling the fixed pressing plate to move relative to the fixing platform 290 according to the positioning point, so that the fixed pressing plate sequentially fixes the plurality of flexible circuit boards on the roll-up circuit board 300 in the exposure area.

[0082] Specifically, the fixing platform 290 is fixedly connected with the second surface of the equipment frame 100 through the platform support rod 250, and the fixing platform 290 is provided with an exposure area. After the roll-up circuit board 300 enters the exposure area, the identification device on the fixing platform 290 identifies the positioning point, so as to ensure that one flexible circuit board on the roll-up circuit board 300 is located in the exposure area, and the fixed pressing plate is controlled to move towards the fixing platform 290, so as to press the flexible circuit board in the exposure area by the fixed pressing plate, facilitating the exposure of the exposure module.

[0083] In an optional embodiment, the fixing platform 290 is further provided with a vacuum suction device. When the fixed pressing plate presses the flexible circuit board in the exposure area, the vacuum suction device is used to perform vacuum suction on the flexible circuit board in the exposure area, so as to make the flexible circuit board flat and exclude air, preventing the air from affecting the flatness of the flexible circuit board when the fixed pressing plate presses the flexible circuit board. It can be predicted that the vacuum suction device stops vacuum suction after the exposure is completed, and details are not described herein.

[0084] In an optional embodiment, the fixed platform 290 is provided with a first position recognition device 240 at the starting position of the exposure area and a second position recognition device 241 at the ending position of the exposure area, and the control of the fixed platform 290 to recognize the position point of the coiled circuit board 300 comprises: in the case that the first position recognition device 240 recognizes the Nth identification point on the coiled circuit board 300, the Nth identification point representing the position point of the Nth flexible circuit board on the coiled circuit board 300, the N representing a positive integer greater than or equal to 1, the coiled circuit board 300 is continuously pulled; and in the case that the second position recognition device 241 recognizes the Nth identification point, the pulling of the coiled circuit board 300 is stopped so that the Nth flexible circuit board is located in the exposure area.

[0085] Specifically, after the first position recognition device 240 recognizes the position point on the Nth flexible circuit board on the coiled circuit board 300 (i.e. the Nth identification point), the coiled circuit board 300 is continuously moved until the second position recognition device 241 recognizes the same position point (the Nth identification point), and the coiled circuit board 300 is stopped, at which time the Nth flexible circuit board is located in the exposure area. For example, after the first position recognition device 240 recognizes the position point on the first flexible circuit board on the coiled circuit board 300 (i.e. the first identification point), the coiled circuit board 300 is continuously moved until the second position recognition device 241 recognizes the first identification point, and the coiled circuit board 300 is stopped, at which time the first flexible circuit board is located in the exposure area and is exposed by the exposure module.

[0086] In an optional embodiment, the fixed pressing plate comprises a fixed frame 200, a transparent plate 210 fixed in the fixed frame 200, and a moving device connected with the fixed frame 200, and the control of the fixed pressing plate to move relative to the fixed platform 290 according to the position point so that the fixed pressing plate fixes the plurality of flexible circuit boards on the coiled circuit board 300 in the exposure area in turn comprises: the control of the moving device to move in a first direction so that the moving device drives the fixed frame 200 and the transparent plate 210 to move in the first direction; and the transparent plate 210 after moving in the first direction fixes the plurality of flexible circuit boards on the coiled circuit board 300 in the exposure area in turn, and the transparent plate 210 completely covers the exposure area.

[0087] Specifically, after the flexible circuit board enters the exposure area, the position of the flexible circuit board and the exposure area is determined by recognizing the positioning point on the flexible circuit board, and corresponding adjustment information is generated, so that the moving device is adjusted according to the adjustment information, the moving device moves the fixed frame 200, so that the position of the transparent plate 210 in the fixed frame 200 is adjusted, and the flexible circuit board is completely pressed in the exposure area through the transparent plate 210. The light beam of the exposure module passes through the transparent plate 210 to expose the flexible circuit board in the exposure area. In some embodiments, one end of the fixed frame 200 close to the entrance side is fixedly connected with the second cylinder rod 231 of the second moving device through the second fixed block 230, and the second cylinder rod 231 is connected with the second cylinder assembly 232; one end of the fixed frame 200 close to the exit side is fixedly connected with the first cylinder rod 221 of the first moving device through the first fixed block 220, and the first cylinder rod 221 is connected with the first cylinder assembly 222; wherein, the first cylinder assembly 222 and the second cylinder assembly 232 have the same structure and synchronously adjust the transparent plate 210.

[0088] In an optional embodiment, the moving device includes a cylinder rod and a cylinder assembly, the cylinder rod is fixedly connected with the fixed frame 200, the cylinder assembly includes a first direction cylinder, a second direction cylinder and a third direction cylinder, the first direction cylinder is used to move the cylinder rod in a first direction, the second direction cylinder is used to move the cylinder rod in a second direction, and the third direction cylinder is used to move the cylinder rod in a third direction, the first direction, the second direction and the third direction are perpendicular to each other, and the fixed frame 200 is provided with a first detection device, and the method further includes: detecting a first offset of the flexible circuit board in the exposure area by the first detection device, the first offset represents the fitting degree of the flexible circuit board and the exposure area; and controlling the first direction cylinder, the second direction cylinder and / or the third direction cylinder to perform a deviation correction process on the transparent plate 210 according to the first offset, so that the transparent plate 210 completely covers the flexible circuit.

[0089] Specifically, the first detection device provided on the fixed frame 200 can be a video detection device, a light detection device, etc., which is not limited here. The first detection device detects the first offset of the flexible circuit board located in the exposure area, that is, the degree of adhesion between the flexible circuit board and the exposure area. Among them, the first directional cylinder in the cylinder assembly (that is, the first cylinder assembly 222 or the second cylinder assembly 232) drives the cylinder rod (that is, the first cylinder rod 221 or the second cylinder rod 231) in the first direction, the second directional cylinder drives the cylinder rod in the second direction, and the third directional cylinder drives the cylinder rod in the third direction. It can be seen that in the cylinder assembly, the first directional cylinder pushes the cylinder rod to move in the first direction, the second directional cylinder pushes the first cylinder and the third cylinder to move in the second direction, thereby pushing the cylinder rod to move in the second direction. Similarly, the third directional cylinder pushes the first cylinder and the second cylinder to move in the third direction, thereby pushing the cylinder rod to move in the third direction. Specific cylinder driving information is generated based on the first offset detected by the first detection device, and the first direction cylinder, the second direction cylinder and / or the third direction cylinder are driven by the cylinder driving information, so that the cylinder rod is adjusted by the first direction cylinder, the second direction cylinder and / or the third direction cylinder, and then the position of the transparent plate 210 is adjusted, so that the transparent plate 210 completely covers the flexible circuit board, thereby preventing the transparent plate 210 from not completely covering the flexible circuit board, resulting in some areas on the flexible circuit board not being fully exposed, thereby reducing the exposure quality.

[0093] Specifically, the first surface of the device frame 100 is the upper surface of the inner wall of the device frame 100, and the second surface of the device frame 100 is the lower surface of the inner wall of the device frame 100. The sliding guide rail 110 is fixedly arranged on the first surface of the device frame 100, and the length of the sliding guide rail 110 is greater than or equal to the straight-line distance from the starting position to the ending position of the exposure area, so that the exposure device 120 can slide above each position of the exposure area on the sliding guide rail 110, thereby emitting a corresponding light beam to expose the flexible circuit board. Specifically, the light beam emitted by the exposure device 120 is a rectangular light beam, the length of the rectangular light beam is greater than or equal to the width of the exposure area, the width of the exposure area is perpendicular to the straight line from the starting position to the ending position of the exposure area, and the length direction of the rectangular light beam is parallel to the width direction of the exposure area. By controlling the exposure device 120 to slide on the sliding guide rail 110, the light beam emitted by the exposure device 120 can be sequentially irradiated from the starting position to the ending position of the exposure area, or from the ending position to the starting position of the exposure area.

[0094] In some optional embodiments, the exposure device 120 can adjust the angle of the emitted light beam, so that the exposure device 120 can complete the exposure without moving, and the exposure efficiency is high.

[0095] S340, output the exposed flexible circuit board from the outlet of the flexible circuit board production and exposure device.

[0096] Specifically, the exposed flexible circuit board (exposed circuit board) is pulled to the outlet of the flexible circuit board production and exposure device, and is output from the outlet of the flexible circuit board production and exposure device, and is then wound and stored by the second storage roller.
