The lower end of the long rotating shaft 10 passes through the operating table 1 and is rotatably connected to the inner wall of the operating table 1. The middle part of the long rotating shaft 10 is rotatably connected to the inner wall of the limiting seat 11, which can limit the long rotating shaft 10 to only rotate; when the motor 7 is started, the long rotating shaft 10 can be driven to rotate. When the long rotating shaft 10 rotates, the carrying arm 15 and the carrying plate 21 can rotate synchronously in a circle, thereby carrying the reinforcement sheet 51 to a specified position.

A top cover 13 is also fixedly connected to the upper end surface of the long rotating shaft 10, and a first spring 14 matched with the transport arm 15 is fixedly connected to the lower end surface of the top cover 13. A first support seat 16 is fixedly connected to the lower end surface of the transport arm 15, and a first sliding pin 17 is fixedly connected to the inner wall of the lower end of the first support seat 16. A first V-shaped groove 19 and a second V-shaped groove 18 matched with the first sliding pin 17 are formed on the upper end surface of the cylindrical cam 12. The first V-shaped groove 19 is aligned with the stripping plate, and the second V-shaped groove 18 is aligned with the conveying rack 3.

[0036] like Figure 5-Figure 7 As shown, the transport arm 15 and the long rotating shaft 10 are spline-connected, that is, the transport arm 15 can slide up and down on the outer surface of the long rotating shaft 10, and when the long rotating shaft 10 rotates, the transport arm 15 can be driven to rotate; the transport arm 15, the first spring 14, and the top cover 13 are installed and shaped as shown in FIG. Figure 6As shown, the top cover 13 supports and fixes the first spring 14, and the first spring 14 always has a downward driving force on the transport arm 15, even if the first sliding pin 17 always contacts the upper end surface of the cylindrical cam 12, that is, it can stably cooperate with the cylindrical cam 12; the first support plate supports and fixes the first sliding pin 17; through the cooperation of the first sliding pin 17, the first V-shaped groove 19, and the second V-shaped groove 18, when the long rotating shaft 10 rotates, it can drive the transport arm 15, the transport plate 21, the suction cup 22, the first sliding pin 17, etc. to rotate synchronously, and when the first sliding pin 17 rotates to the first V-shaped groove 19, that is, the transport plate 21 rotates to reach the support platform 36 and the reinforcing sheet 51, at this time, the first sliding pin 17 can rotate and move downward under the meshing of the first V-shaped groove 19, that is, the transport plate 21 and the suction cup 22 can be rotated and moved downward, and the transport plate 21 and the suction cup 22 can be moved downward a short distance when they rotate to the corresponding designated position. Under the meshing of the first sliding pin 17 and the first V-shaped groove 19, the suction cup 22 can be rotated and moved downward, so that the suction cup 22 contacts the reinforcing sheet 51 at the upper end of the support platform 36. After the reinforcing sheet 51 is adsorbed and fixed, when the long shaft 10 continues to rotate , the first sliding pin 17 and the first V-shaped groove 19 are meshed, and the first sliding pin 17, the transport plate 21, and the reinforcing sheet 51 are rotated and moved upward for a distance, so that the reinforcing sheet 51 is out of contact with the support platform 36 to prevent movement negotiation; when the long rotating shaft 10 rotates to make the transport arm 15, the transport plate 21, the suction cup 22, and the reinforcing sheet 51 reach the upper end position of the conveying rack 3, the first sliding pin 17 and the second V-shaped groove 18 are meshed, so that the transport arm 15, the transport plate 21, the suction cup 22, the reinforcing sheet 51, etc. can be rotated and moved downward. When the first sliding pin 17 reaches the second V-groove 18 is at the bottom, at this time, the reinforcing sheet 51 moves to the bottom position and can contact the flexible circuit board 5 on the upper end of the fixture seat 4, so that the reinforcing sheet 51 is attached to the flexible circuit board 5. When the long rotating shaft 10 continues to rotate, under the engagement of the first sliding pin 17 and the second V-shaped groove 18, the conveying arm 15, the conveying plate 21, the suction cup 22, etc. can be rotated and moved upward to prevent the suction cup 22, the conveying plate 21 from moving against the conveying frame 3. It can be recycled and used repeatedly to attach the reinforcing sheet 51 to the corresponding flexible circuit board 5 in turn, and the whole process is automated to form an assembly line production mode.

[0037] A long support plate 23 is fixedly connected to the outer surface of the long rotating shaft 10 , a movable square sleeve 24 is slidably connected to the inner wall of the long support plate 23 , an L-shaped connecting rod 25 is fixedly connected to the inner wall of the square sleeve 24 , and the glue spraying plate 26 is fixedly connected to the L-shaped connecting rod 25 .

[0038] like Figure 8As shown, the square sleeve 24 can be slidably connected to the inner wall of the long support plate 23 forward and backward, that is, the limiting L-shaped connecting rod 25 and the glue spraying plate 26 can only move on the long support plate 23. When the square sleeve 24 moves forward and backward, the radius of the circular movement of the glue spraying plate 26 can be changed. Even if the glue spraying plate 26 moves to a position corresponding to the reinforcing plate 51, the long support plate 23 is fixedly connected to the long rotating shaft 10. When the long rotating shaft 10 rotates, the long support plate 23 can be driven to rotate. When the long support plate 23 rotates, it will drive the square sleeve 24 and the L-shaped connecting rod 25 to rotate synchronously in a circular manner. When the L-shaped connecting rod 25 rotates in a circular manner, it will drive the glue spraying plate 26 to rotate synchronously in a circular manner. When the square sleeve 24 moves forward and backward, it will drive the glue spraying plate 26 to move forward and backward, so that the glue spraying plate 26 moves to the lower end of the reinforcing plate 51.

[0039] The upper end surface of the operating table 1 is fixedly connected to a track plate 29, and the lower end surface of the L-shaped connecting rod 25 is fixedly connected to a second sliding pin 27. The track plate 29 is provided with a track groove matched with the second sliding pin 27, and the track groove includes an arc groove 30, a first diameter-reducing groove 31, a wave groove 32, and a second diameter-reducing groove 33. When the second sliding pin 27 is engaged with the arc groove 30, the glue spraying plate 26 can be located at the innermost end of the long support plate 23 when the L-shaped connecting rod 25 and the second sliding pin 27 rotate in a circle. When the second sliding pin 27 is engaged with the first diameter-reducing groove 31, the glue spraying plate 26 can be located at the innermost end of the long support plate 23. When engaged, when the L-shaped connecting rod 25 and the second sliding pin 27 rotate in a circle, the glue spraying plate 26 can move outward at the upper end of the long support plate 23. When the second sliding pin 27 is engaged with the wave groove 32, when the L-shaped connecting rod 25 and the second sliding pin 27 rotate in a circle, the glue spraying plate 26 can reciprocate and oscillate at the outermost end of the long support plate 23. When the second sliding pin 27 is engaged with the second reducing groove 33, when the L-shaped connecting rod 25 and the second sliding pin 27 rotate in a circle, the glue spraying plate 26 can move inward at the upper end of the long support plate 23.

[0040] like Figure 8-Figure 9As shown, by the meshing of the set track plate 29, the track groove and the second sliding pin 27, the movement of the second sliding pin 27, the L-shaped connecting rod 25 and the glue spraying plate 26 can be controlled. When the glue spraying plate 26 moves in the direction close to the long rotating shaft 10 at the upper end of the long supporting plate 23, it moves inward, and when it moves away from the long rotating shaft 10, it moves outward; when the first sliding pin 17 moves in a circular motion on the inner wall of the arc groove 30, the glue spraying plate 26 can move in a circular motion at the innermost end to prevent movement negotiation with the driven shaft 34, the conveying rack 3, etc.; when the first sliding pin 17 moves in a circular motion on the inner wall of the first diameter-reducing groove 31, the glue spraying plate 26 can move outward, that is, the glue spraying plate 26 moves to the position corresponding to the lower end of the reinforcing plate 51, when the first sliding pin 17 moves in a circular motion on the inner wall of the first diameter-reducing groove 31, the glue spraying plate 26 can move outward. When the pin 17 rotates in a circle on the inner wall of the wave groove 32, the glue spraying plate 26 moves outward to the top position, that is, moves to the middle position of the lower end of the reinforcing sheet 51. At this time, the glue spraying port 28 sprays glue or adhesive upward, and under the engagement of the first sliding pin 17 and the wave groove 32, the glue spraying plate 26 can be driven to oscillate reciprocatingly inward and outward with a small amplitude. During the reciprocating oscillating movement, the glue spraying port 28 can scan and spray glue to the lower end surface of the reinforcing sheet 51, so that the lower end surface of the reinforcing sheet 51 is completely covered with glue. When the first sliding pin 17 moves in a circle on the inner wall of the second diameter-changing groove 33, the glue spraying plate 26 can be moved inward, that is, the glue spraying plate 26 moves inward to the top to prevent movement interference with other parts.

[0041] The cylindrical cam 12 is provided with a trapezoidal groove 20 that matches with the first sliding pin 17 , and the trapezoidal groove 20 is arranged corresponding to the wave groove 32 .

[0042] like Figure 4 or Figure 7-Figure 9As shown, through the meshing of the trapezoidal groove 20 and the first sliding pin 17, when the first sliding pin 17 rotates in a circle, the first sliding pin 17 can move downward, that is, the corresponding carrying arm 15, carrying plate 21, suction cup 22, reinforcing sheet 51, etc. move synchronously while moving in a circle and downward. When the first sliding pin 17 moves downward to the inner wall of the bottom end of the trapezoidal groove 20, that is, the bottom end and continues to move in a circle, the corresponding carrying arm 15, carrying plate 21, reinforcing sheet 51, etc. will move in a circle at the bottom end. When the first sliding pin 17 continues to rotate in a circle on the inner wall of the trapezoidal groove 20 to a specified position, the first sliding pin 17, carrying arm 15, carrying plate 21, reinforcing sheet 51, etc. will move upward to a specified position, even if the reinforcing sheet 51 moves to the upper end position of the conveying rack 3 to prepare, to prevent movement negotiation with the conveying rack 3; the long support plate 23 is correspondingly arranged with the carrying arm 15, and the trapezoidal groove 20 is correspondingly arranged with the wave groove 32. When the long rotating shaft 1 0 rotates, it can drive the transport arm 15, the reinforcing sheet 51, etc. to rotate synchronously, and the corresponding long support plate 23 and the glue spraying plate 26 will rotate synchronously with the transport arm 15 and the reinforcing sheet 51. When the transport arm 15, the reinforcing sheet 51, the long support plate 23, the glue spraying plate 26, etc. rotate to be away from the supporting platform 36, the transport arm 15, the reinforcing sheet 51, etc. will rotate and move downward under the engagement of the first sliding pin 17 and the trapezoidal groove 20, and the corresponding glue spraying plate 26 will rotate and move outward under the engagement of the second sliding pin 27 and the first diameter-reducing groove 31. When the transport arm 15 and the reinforcing sheet 51 rotate and move to the bottom end, the corresponding glue spraying plate 26 will move outward to the top end, that is, the second sliding pin 27 enters the inner wall of the wave groove 32. At this time, the reinforcing sheet 51 can move down a distance and then approach the glue spraying plate 26. When the glue spraying plate 26 sprays glue, it can be more accurately sprayed onto the lower end surface of the reinforcing sheet 51, thereby improving the glue spraying efficiency.

[0043] A driving pulley 8 is fixedly connected to the lower end of the outer surface of the long rotating shaft 10, a driven pulley 9 is connected to one side of the driving pulley 8, a driven shaft 34 is fixedly connected to the inner wall at the center of the driven pulley 9, a vertical plate 50 is also fixedly connected to the upper end surface of the operating table 1, the supporting platform 36 is fixedly connected to the end surface of one side of the vertical plate 50, a feeding plate 38 is provided on the upper end of the supporting platform 36, a reinforcing sheet 51 is placed on the upper end surface of the feeding plate 38, a threaded rod 35 is rotatably connected to the lower end surface of the feeding plate 38, the threaded rod 35 is slidably connected to the upper end of the outer surface of the driven shaft 34, and two incomplete threaded seats 46 matching the threaded rod 35 are installed on the inner wall in the middle of the supporting platform 36.

[0044] like Figure 10-11As shown, through the belt connection between the driving pulley 8 and the driven pulley 9, the driven shaft 34 can be made to rotate synchronously with the long rotating shaft 10; the driven shaft 34 is rotatably connected to the inner wall of the operating table 1, and the feeding plate 38 is limited by the right-angle seat 39, so that the feeding plate 38 can only move up and down on the upper end of the supporting platform 36; the threaded rod 35 can be slidably connected to the outer surface of the driven shaft 34 up and down, and the threaded rod 35 and the driven shaft 34 are splined, that is, when the driven shaft 34 rotates, it can drive the threaded rod 35 to rotate; when the long rotating shaft 10 rotates, it will drive the driving pulley 8, the driven pulley 9, and the driven pulley 36. The shaft 34 rotates, and when the driven shaft 34 rotates, it will drive the threaded rod 35 to rotate. When the threaded rod 35 rotates, it can move upward through the threaded connection with the two incomplete threaded seats 46. When the threaded rod 35 moves upward, it will drive the corresponding feeding plate 38 to move upward. When the feeding plate 38 moves upward, it will drive the reinforcement sheet 51 to move upward. After taking the reinforcement sheet 51 at the top, the feeding plate 38 can slowly move upward to the next reinforcement sheet 51 to reach the specified height position, so that the conveying plate 21 and the suction cup 22 can take the reinforcement sheet 51 again.

[0045] The lower end surface of the supporting platform 36 is provided with a rotatable disc 37, and the incomplete threaded seats 46 are slidably connected to the inner walls of the supporting platform 36, and the lower end surfaces of the supporting platform 36 are fixedly connected with extension rods 44, and the outer ends of the two extension rods 44 are fixedly connected with third sliding pins 45, and the disc 37 is provided with oblique key grooves 43 that match the third sliding pins 45.

[0046] like Fig.12 As shown, the disc 37 is rotatably connected to the lower end surface of the supporting platform 36, and a first handle 40 is also fixedly connected to one side of the lower end surface of the disc 37. The function of the first handle 40 is to facilitate driving the disc 37 to rotate; the incomplete threaded seat 46 can be slidably connected to the inner wall of the supporting platform 36 left and right, and the extension rod 44 supports and fixes the third sliding pin 45. Through the engagement of the third sliding pin 45 with the oblique key groove 43, when the disc 37 rotates, it can drive the corresponding incomplete threaded seat 46 to move synchronously inward or outward. When the incomplete threaded seat 46 moves inward, it can engage with the threaded rod 35, that is, the threaded rod 35 is threadedly connected to the inner walls of the two incomplete threaded seats 46. When the incomplete threaded seat 46 moves outward, it can disengage from the threaded rod 35, that is, the threaded rod 35 is no longer threadedly connected to the incomplete threaded seat 46. At this time, the threaded rod 35 and the feeding plate 38 can move downward and return to the initial state under the action of their own gravity.

[0047] The upper end surface of the support platform 36 is slidably connected with four evenly distributed right-angle seats 39 , the lower ends of the right-angle seats 39 are respectively hinged with first connecting rods 41 , and the other ends of the first connecting rods 41 are respectively hinged to the lower end surface of the disc 37 .

[0048] like Fig.11As shown, the lower end surfaces of the right-angle seats 39 are respectively fixed with first sliders 42, and the first sliders 42 are respectively slidably connected to the inner walls of the support platform 36, which is equivalent to the right-angle seats 39 being slidably connected to the support platform 36. When the right-angle seats 39 are at the innermost end, they can limit the feeding plate 38, and at the same time limit the reinforcing sheet 51, so that the reinforcing sheet 51 can only move up and down. When the disc 37 rotates, the two right-angle seats 39 can be driven to move outward or inward through the hinge connection between the first connecting rod 41 and the right-angle seats 39. When the right-angle seats 39 move from the outside to the inside, the reinforcing sheet 51 can also be calibrated so that the reinforcing sheet 51 is in the middle of the feeding plate 38. After the reinforcing sheet 51 at the upper end of the feeding plate 38 is used up, when the reinforcing sheet 51 needs to be replenished, the disc 37 is rotated by rotating the first handle 40. When the disc 37 rotates, the two incomplete thread seats 46 are driven to move outward, that is, the incomplete thread seats 46 are disengaged from the threaded rod 35. At this time, the threaded rod 35 and the feeding plate 38 will drop to the bottom position and reset under the action of their own gravity. When the disc 37 rotates, the multiple right-angle seats 39 will also move outward, that is, the space at the upper end of the feeding plate 38 is larger, which is convenient for placing the reinforcing sheet 51. When the disc 37 is flipped over, the right-angle seats 39 can be moved inward to calibrate the reinforcing sheet 51 and limit it.

[0049] A first tension spring seat 47 is provided on one side of the lower end surface of the disc 37 , and a second tension spring seat 49 is rotatably connected to the lower end surface of the supporting platform 36 . A long tension spring 48 is provided between the first tension spring seat 47 and the second tension spring seat 49 .

[0050] like Fig.12 As shown, under the tension of the long tension spring 48, the disc 37 can have a reverse rotational force, even if the two incomplete threaded seats 46 are at the innermost end under normal circumstances, they can be stably engaged with the threaded rod 35, and the right-angle seat 39 is at the innermost end under normal circumstances, which can limit the feeding plate 38 and the right-angle seat 39.

[0051] When the present invention is in use, the motor 7 is started to rotate the long rotating shaft 10, which can drive the transport plate 21 and the suction cup 22 to rotate synchronously. When the suction cup 22 and the transport plate 21 rotate to the specified position, that is, the upper end position of the reinforcing sheet 51, the reinforcing sheet 51 can be adsorbed and fixed under the operation of the suction cup 22, that is, the transport plate 21 can drive the reinforcing sheet 51 to move synchronously when moving; when it is necessary to attach the reinforcing sheet 51 to the flexible circuit board 5, the long rotating shaft 10 is driven to rotate, and when the long rotating shaft 10 rotates, the transport plate 21, the suction cup 22, the reinforcing sheet 51 and the like can be driven to move synchronously in a circular motion. When the reinforcing sheet 51 moves in a circular motion to the specified position, the glue spraying plate 26 can move synchronously in a circular motion with the reinforcing sheet 51, and the glue spraying port 28 is opened to work, so as to be able to spray the reinforcing sheet 51 downward. The end surface is sprayed with glue to replace the traditional manual gluing. When the conveying plate 21, the suction cup 22, and the reinforcing sheet 51 continue to rotate to the specified position, that is, rotate to make the reinforcing sheet 51 on the flexible circuit board 5, the suction cup 22 is controlled to no longer adsorb the reinforcing sheet 51, so that the reinforcing sheet 51 can be attached to the flexible circuit board 5. A heating box 6 is provided on the rear side of the upper end of the operating table 1, and the conveying frame 3 passes through the heating box 6. When the reinforcing sheet 51 is attached to the upper end surface of the flexible circuit, the conveying frame 3 can transport the fixture seat 4, the flexible circuit board 5, and the reinforcing sheet 51 to the heating box 6, and can heat the flexible circuit board 5, the reinforcing sheet 51, the adhesive or glue to make the reinforcing sheet 51 and the flexible circuit board 5 fit more firmly. Fully automated production can be achieved, which reduces the occupation of human resources and improves production efficiency.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the scope defined by the spirit of the present invention.
