Therefore, when removing the flexible circuit board, it is necessary to move up to separate from the position limit rod, and then to patch, but the pad can be taken away directly, and the movement trajectories of the two are not synchronized. The existing device cannot achieve synchronous separation of the pad and the circuit board, and multiple additional grabbing mechanisms need to be set up; 2.

[0051] In this embodiment, when the limiting slide bar 33 and the mounting seat 21 move to the e section, the outer adjustment slide rail 12 and the inner adjustment slide rail 18 are parallel to the outer slide rail 9 and the inner slide rail 10 again, so that the pad 27 remains in a horizontal state, and at the same time, the bearing seat 3 moves to the top of the threaded rod 24, so that the second gear rod 43 is squeezed and moved by the first slide groove 45, and the second gear rod 43 drives the second gear 41 and the rotating column 42 to rotate. Due to the action of the limiting rod 3 54, the upper push plate 23 moves upward to lift up the flexible circuit board 26 with the patch completed above, so that the pad 27 can be inserted between the bearing seat 3 and the flexible circuit board 26 at this time, and then The upper push plate 23 retracts, and when the rotating gear rod 40 conflicts with the third slide groove 47 and the second slide groove 46, the rotating gear rod 40 will drive the gear 2 52 to rotate, and the gear 2 52 will drive the arc slide bar 24 to rotate, so that the arc slide bar 24 will not hinder the finished product seat 5.

When the limiting slide bar 33 moves to section d, the outer adjustment rail 12 and the inner adjustment rail 18 are staggered with the outer rail 9 and the inner rail 10, so that the pad 27 is still in a horizontal state at this time. When the patch is completed, the first motor 6 can drive the threaded rod 24 to rotate, so that the bearing seat 3 moves up along the main bracket 4, and the arc slide bar 24 is separated from the position limiting rod 25.

[0055] In this embodiment, when the limiting rod 31 conflicts with the trapezoidal protrusion 30, the limiting rod 31 drives the adsorption assembly 28 to move to the bottom of the mounting seat 21, so that the adsorption assembly 28 will not knock off the placed pad 27, and the second motor 20 can rotate to adjust the height of the finished product seat 5.
[0056] The specific working principle and method of use of the present invention are explained in detail below: first, when the employee stacks the flexible circuit board 26 and the pad 27 on the material carrier plate 22, the flexible circuit board 26 needs to be stacked in reverse so that when the flexible circuit board 26 is flipped onto the carrier seat 3 along the position limit rod 25 and the arc slide rod 24, the side of the flexible circuit board 26 to be patched faces the patch assembly 17.
[0057] When in use, the material carrying plate 22 is placed on the base 1, and the third motor 53 starts to rotate, so that the displacement gear 34 can move downward along the first gear block group 37, so that the adsorption component 28 can absorb the uppermost pad 27. Figure 4 As shown, at this time, the opening of the adsorption assembly 28 faces downward, and the pad 27 is perpendicular to the outer slide rail 9 and the inner slide rail 10 where the limiting slide rod 33 is located. Then, the third motor 53 drives the displacement gear 34 to move along the first gear block group 37, so that the mounting seat 21 drives the adsorption assembly 28 and the pad 27 to move upward, as shown in FIG. Figure 8 In the direction shown, when the limit slide bar 33 moves to the intersection of a and b and turns, the pad 27 will drive the flexible circuit board 26 to flip over along the arc slide rail composed of the position limit rod 25 and the arc slide bar 24. Since the arc slide bar 24 and the position limit rod 25 have the same diameter, all the flexible circuit boards 26 can fall on the supporting seat 3 at the same position, without any complicated positioning mechanism, and the subsequent patch process can be carried out. At this time, the pad 27 is in a vertical state.
[0058] like Figure 8 As shown, the limit slide bar 33 continues to move. At this time, the mounting seat 21 moves along the track composed of the outer adjustment slide rail 12 and the inner adjustment slide rail 18. Since the distance between the mounting seat 21 and the limit slide bar 33 is fixed, when the mounting seat 21 moves upward along the slope of the outer adjustment slide rail 12 and the inner adjustment slide rail 18, the track composed of the outer adjustment slide rail 12 and the inner adjustment slide rail 18 is parallel to the track composed of the outer slide rail 9 and the inner slide rail 10, so that the pad 27 changes from a vertical state to a horizontal state, so that the pad 27 will not block the patch component 17 from patching the flexible circuit board 26. When the limit slide bar 33 moves to section d, the outer adjustment slide rail 12 and the inner adjustment slide rail 18 are staggered with the outer slide rail 9 and the inner slide rail 10, so that the pad 27 is still in a horizontal state at this time. When the patch is completed, the first motor 6 can drive the threaded rod 24 to rotate, so that the bearing seat 3 moves up along the main bracket 4, and the arc slide bar 24 is separated from the position limit rod 25.
[0059] When the limiting slide bar 33 and the mounting seat 21 move to section e, the outer adjustment slide rail 12 and the inner adjustment slide rail 18 are parallel to the outer slide rail 9 and the inner slide rail 10 again, so that the pad 27 remains in a horizontal state, and at the same time, the supporting seat 3 moves to the top of the threaded rod 24, so that the second gear rod 43 is squeezed and moved by the first slide groove 45, and the second gear rod 43 drives the second gear 41 and the rotating column 42 to rotate. Due to the action of the limiting rod 3 54, the upper push plate 23 moves upward to lift up the flexible circuit board 26 with the patch completed above, so that the pad 27 can be inserted between the supporting seat 3 and the flexible circuit board 26, and then the upper push plate 23 retracts, and when the rotating gear rod 40 conflicts with the third slide groove 47 and the second slide groove 46, the rotating gear rod 40 will drive the gear 2 52 to rotate, and the gear 2 52 will drive the arc slide bar 24 to rotate, so that the arc slide bar 24 will not hinder the finished product seat 5. When the bearing seat 3 moves to the top of the threaded rod 24, the arc slide bar 24 is reset. At this time, the limiting slide bar 33 continues to slide so that the pad 27 moves the flexible circuit board 26 to the finished product seat 5 in the same way, and then the adsorption component 28 releases the pad 27 so that the pad 27 is on the flexible circuit board 26, and then the positioning and placement of the flexible circuit board 26 and the pad 27 are completed.
[0060] When the second limiting rod 31 contacts the trapezoidal protruding rod 30 , the second limiting rod 31 drives the adsorption assembly 28 to move to the bottom of the mounting seat 21 , so that the adsorption assembly 28 will not knock off the placed pad 27 , and the second motor 20 can rotate to adjust the height of the finished product seat 5 .
[0061] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
