[0041] A second motor 39 is fixedly connected to the support frame 18, a large disc 40 is fixedly connected to the output end of the second motor 39, four evenly distributed first guide rods 43 are slidably connected to the outer circumference of the large disc 40, key plates 42 are fixedly connected to the upper end surfaces of the first guide rods 43, third springs 44 matching the key plates 42 are respectively sleeved on the outer surfaces of the first guide rods 43, square tubes 45 are fixedly connected to the lower end surfaces of the first guide rods 43, square rods 46 are slidably connected to the inner walls of the square tubes 45, first tension springs 47 matching the square rods 46 are respectively fixedly connected to the inner walls of the bottom ends of the square tubes 45, and the feeding devices include transport plates 48, which are respectively fixed to the corresponding square rods 46.

[0042] like Figure 13-Figure 14As shown, the function of the second motor 39 is to provide a rotational force for the large disc 40. The motor is a prior art and will not be described in detail. Limiting guide rods 41 are respectively provided on both sides of the first guide rod 43. The limiting guide rods 41 are respectively connected to the inner wall of the large disc 40 by sliding up and down. The lower ends of the limiting guide rods 41 are respectively fixed to the square cylinder 45, and the upper ends of the limiting guide rods 41 are respectively fixed to the key-shaped plate 42. By setting the limiting guide rods 41 and the first guide rods 43, the square cylinder 45 can be limited to move up and down at the lower end of the large disc 40. The third spring 44 always has an upward elastic force on the key-shaped plate 42.

The first tension spring 47 always has an inward pulling force on the square rod 46, so that the square rod 46 is at the innermost end under normal conditions. Through the limitation of the square tube 45 on the square rod 46, the feeding device, that is, the transport plate 48 can only move inward or outward on the square tube 45, and under the pulling force of the first tension spring 47, the feeding device and the transport plate 48 can be at the innermost end under normal conditions; through the limitation of the first guide rod 43, the limiting guide rod 41, the square tube 45, and the square rod 46, the transport plate 48 can move up and down and forward and backward at the lower end of the large disc 40, which is convenient for the feeding device to transport the flexible circuit board.

[0044] like Figure 13-Figure 15 As shown, cylindrical rods are fixedly connected at both ends of the outer clamping plate 53, and the cylindrical rods are fixedly connected to the transport plate 48, which is equivalent to the outer clamping plate 53 being fixedly connected to the transport plate 48. The second guide rod 50 can be slidably connected to the inner wall of the transport plate 48 forward and backward, that is, the limited inner clamping plate 52 can only move forward and backward. The two fourth springs 51 always have a forward driving force on the inner clamping plate 52, so that the inner clamping plate 52 can squeeze the outer clamping plate 53 under normal conditions. By placing the flexible circuit board between the outer clamping plate 53 and the inner clamping plate 52, the flexible circuit board can be fixed on the transport plate 48 under the extrusion of the fourth spring 51 and the inner clamping plate 52, and when the transport plate 48 moves up and down or moves forward and backward or moves in a circle, the flexible circuit board can be driven to reach the specified position; through the setting of the connecting frame 49, when the connecting frame 49 moves backward, it can drive the second guide rod 50 and the inner clamping plate 52 to move forward and backward, and when the inner clamping plate 52 moves backward, it can no longer squeeze the flexible circuit board.

[0045] The support frame 18 is also fixedly connected to a first motor 19, and a cylindrical cam 37 is fixedly connected to the output end of the first motor 19. Two long guide rods 35 are fixedly connected to the lower end surface of the support frame 18. The annular sleeve 33 is sleeved on the outer surfaces of the two long guide rods 35. The inner wall of the annular sleeve 33 is fixedly connected to a third sliding pin 38 meshing with the cylindrical cam 37. The left and right sides of the lower end surface of the annular sleeve 33 are respectively fixedly connected to L-shaped pressure rods 34, and the upper end surface of the transport plate 48 is respectively fixedly connected to upper sliding rods 54 that cooperate with the L-shaped pressure rod 34.

[0046] like Figure 8-Figure 15 As shown, the function of the first motor 19 is to provide a rotating force for the cylindrical cam 37. The motor is a prior art and will not be described in detail. The two long guide rods 35 are provided to limit the annular sleeve 33 to move up and down only at the lower end of the support frame 18, and when the cylindrical cam 37 rotates, the third sliding pin 38 is engaged with the cylindrical cam 37 to drive the annular sleeve 33, the third sliding pin 38, and the L-shaped pressure rod 34 to move up and down intermittently, that is, when the cylindrical cam 37 rotates, the annular sleeve 33 and the L-shaped pressure rod 34 can be driven to move downward, and when the L-shaped pressure rod 34 moves downward to the bottom end, it can stop intermittently, and when the cylindrical cam 37 continues to rotate, the annular sleeve 33 and the L-shaped pressure rod 34 can be driven to move upward, and the L-shaped pressure rod 34 will stop intermittently after moving upward to the top end, that is, when the cylindrical cam 37 is engaged with the third sliding pin 38, the L-shaped pressure rod 34 can have an intermittent stay time when it is at the bottom or top position; as shown in FIG. Fig.16 As shown, after the transport plate 48 rotates to the specified position, when the L-shaped pressure rod 34 moves downward, it can squeeze the upper slide rod 54 to move downward. Through the contact between the upper slide rod 54 and the L-shaped pressure rod 34, the friction force can be reduced, that is, when the L-shaped pressure rod 34 moves downward, it can drive the upper slide rod 54, the transport plate 48, etc. to move downward synchronously, and the upper slide rod 54, the transport plate 48, etc. can move back and forth on the lower end surface of the L-shaped pressure rod 34, and the friction resistance is small.

[0047] The lower end surface of the transport plate 48 is fixedly connected with a lower slide rod 55, and the left and right sides of the upper end surface of the operating platform 1 are fixedly connected with guide plates 58. The guide plates 58 are respectively provided with an inclined surface 56 and a straight surface 57 that match the lower slide rod 55.

[0048] like Figure 15-16As shown, by cooperating with the inclined surface 56 and the straight surface 57 of the guide plate 58, when the L-shaped pressure rod 34 squeezes the upper slide rod 54 to move downward, the lower slide rod 55 can contact the inclined surface 56 of the guide plate 58. Under the action of the inclined surface 56 of the guide plate 58, the transport plate 48 can move downward and forward at the same time, so as to facilitate the transport plate 48 and the flexible circuit board to be transported to the position just above the box body 3. When the lower slide rod 55 moves downward to contact and engage with the straight surface 57, the flexible circuit board will be at the position just above the box body 3. When the L-shaped pressure rod 34 continues to squeeze downward, the flexible circuit board will be at the position just above the box body 3. When the upper slide bar 54 and the transport plate 48 are pressed, the flexible circuit board can move downward into the box body 3. At this time, when the connecting frame 49 moves backward, the inner clamping plate 52 can move backward, that is, the inner clamping plate 52 no longer squeezes the flexible circuit board, and the flexible circuit board can be placed inside the box body 3. When the L-shaped pressure rod 34 moves upward and resets, the corresponding transport plate 48, upper slide bar 54, lower slide bar 55, outer clamping plate 53, inner clamping plate 52, etc. will move upward and reset to the initial state under the elastic force of the third spring 44 and the tension of the first tension spring 47, completing a feeding work cycle.

[0049] The upper end of the cylindrical cam 37 is coaxially fixed with the second disc cam 29, and the lower end surface of the support frame 18 is also slidably connected with a long slide 30, and the inner wall of the front end of the long slide 30 is fixed with a second sliding pin 31 that meshes with the second disc cam 29, and the inner end surfaces of the two L-shaped pressure rods 34 are slidably connected with a horizontal plate 36 that cooperates with the connecting frame 49, and the upper end surface of the horizontal plate 36 is fixed with a vertical plate 32, and the long slide 30 is slidably connected to the inner wall of the vertical plate 32.

[0050] like Fig.11As shown, the long slide 30 can be slidably connected to the lower end surface of the support frame 18, and the long slide 30 is slidably connected to the inner wall of the vertical plate 32, that is, the vertical plate 32 can move up and down on the long slide 30, and when the long slide 30 moves forward and backward, it can drive the vertical plate 32 and the horizontal plate 36 to move forward and backward, and the horizontal plate 36 can be slidably connected to the inner end surface of the L-shaped pressure rod 34. Through the engagement of the second disc cam 29 and the second sliding pin 31, when the second disc cam 29 rotates, it can drive the second sliding pin 31 and the long slide 30 to intermittently reciprocate forward and backward, that is, when the second disc cam 29 rotates, it can drive the second sliding pin 31 to move backward, and when the second sliding pin 31 moves backward to the top position, it can The second slide pin 31 can be driven to move forward when the second disc cam 29 continues to rotate, and can be intermittently stopped for a period of time when the second slide pin 31 moves forward to the top position; through the cooperation of the second disc cam 29 and the cylindrical cam 37, when the second disc cam 29 and the cylindrical cam 37 rotate synchronously, the L-shaped pressure rod 34, the horizontal plate 36, and the vertical plate 32 can be driven to move downward synchronously, and when the L-shaped pressure rod 34 moves downward, the upper slide rod 54, the transport plate 48, the connecting frame 49, the lower slide rod 55, the flexible circuit board, etc. can be driven to move downward. When the lower slide rod 55 moves downward, it can be meshed with the inclined surface 56 to make the transport plate 48, the connecting frame 49, the flexible circuit board, etc. move forward. When the slide bar 55 moves to contact and engage with the straight surface 57, the flexible circuit board can move to the position just above the box body 3, and the connecting frame 49 can move forward to contact with the cross plate 36. After the transport plate 48 moves to the bottom, that is, the flexible circuit board is placed inside the box body 3, the second slide pin 31 and the long slide plate 30 can be moved backward through the engagement of the second disc cam 29 and the second slide pin 31. When the long slide plate 30 moves backward, it can drive the vertical plate 32 and the cross plate 36 to move backward. When the cross plate 36 moves backward, it will drive the connecting frame 49 to move backward. When the connecting frame 49 moves backward, it can drive the inner clamping plate 52 to move backward, that is, the inner clamping plate 52 no longer clamps the flexible circuit board. At this time, the cylindrical cam The engagement of the wheel 37 and the third sliding pin 38 can make the L-shaped clamp rod 27 move upward and reset. Under the action of the third spring 44 and the first tension spring 47, the corresponding upper slide plate, transport plate 48, lower slide rod 55, inner clamp plate 52, outer clamp plate 53, etc. can be moved upward and reset, so that the feeding device is reset upward to the initial position. After the feeding device is reset upward to the initial position, the second disc cam 29 continues to rotate to drive the second sliding pin 31 to move forward, that is, the long slide plate 30, the vertical plate 32, and the cross plate 36 move forward. When the cross plate 36 moves forward, it no longer squeezes the connecting frame 49. At this time, the connecting frame 49 and the inner clamp plate 52 will be reset to the initial position under the elastic force of the fourth spring 51, that is, a feeding cycle is completed and the cycle can be circulated.

[0051] The inner walls at the left and right ends of the support frame 18 are respectively provided with movable clamping rods 27 , and the lower end surfaces of the clamping rods 27 are respectively fixedly connected with U-shaped clamping seats 28 that match the box body 3 .

[0052] like Figure 8 As shown, the clamp rod 27 can be slidably connected to the inner wall of the support frame 18, and the clamp rod 27 can move inward or outward; through the provision of a U-shaped clamp seat 28, when the U-shaped clamp seat 28 moves inward, the box body 3 can be calibrated and fixed, so that it can be more accurate during assembly.

[0053] The upper end of the support frame 18 is provided with a rotatable first disc cam 20, the upper end surface of the support frame 18 is fixedly connected to an L-shaped seat 24, the inner wall of the L-shaped seat 24 is slidably connected to a square slider 25, the inner wall of the square slider 25 is fixedly connected to a first sliding pin 23, the first disc cam 20 is provided with an arc groove 21 and a V-shaped groove 22 that match the first sliding pin 23, the upper end of the outer surface of the first sliding pin 23 is rotatably connected to two long connecting rods 26, and the clamping rods 27 are respectively hinged on the corresponding long connecting rods 26.

[0054] like Figure 8-Figure 10 As shown, the first disc cam 20 is fixedly connected to the output end of the first motor 19. When the first motor 19 is started, the first disc cam 20 can be driven to rotate. Under the limitation of the other slider 25 by the L-shaped seat 24, the slider 25 can be limited and the first sliding pin 23 can only move forward and backward. Under the setting of the arc groove 21 and the V-shaped groove 22, the first disc cam 20 and the first sliding pin 23 are engaged, and the first sliding pin 23 can be driven to move forward after moving to the top end, and can stop intermittently for a period of time after moving forward to the top end; that is, the first sliding pin 23 can drive the first sliding pin 23 to move forward and backward when moving forward and backward. The inner end of the corresponding long connecting rod 26 moves forward and backward, and the outer end of the long connecting rod 26 pulls the corresponding clamping rod 27 to move inward or outward. When the clamping rod 27 moves inward or outward, it can drive the corresponding U-shaped clamping seat 28 to move inward or outward. Therefore, under the mutual cooperation of the first disc cam 20, the second disc cam 29 and the cylindrical cam 37, the feeding device can move the corresponding U-shaped clamping seat 28 inward to calibrate the box body 3 before feeding, and then fix it. After the feeding device feeds, the U-shaped clamping seat 28 moves outward, that is, it is no longer fixed to the box body 3.

[0055] When the present invention is in use, the feeding device can convey and load the flexible circuit board. When the large disc 40 rotates, the flexible circuit board can reach the specified position. By placing the box body 3 on the conveyor belt 2, the box body 3 can be driven to reach the specified position when the conveyor belt 2 moves. Through the provided extrusion device, after the box body 3 and the feeding device reach the specified position, the annular sleeve 33 moves downward, which can drive the feeding device to move downward. When the feeding device moves downward, the flexible circuit board can be inserted into the box body 3. Then, the plug cover 6 is driven downward by the cylinder extrusion, so that the flexible circuit board can be fixed on the FPC connector. The assembly can be completed automatically, replacing manual operation, and the efficiency and precision are high and the dislocation is not easy.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
