[0029] The beneficial effects of the present invention include:

[0030] 1) The frame material conveying mechanism is provided with a lifting and feeding plate that can be lifted and reciprocated to convey the frame material to the position of the frame material turning mechanism, the frame material turning mechanism is provided with an openable and closable frame material clamping mouth for clamping the frame material, the frame material turning mechanism and the steel strip material clamping frame can be adjusted and moved in the two sides of the frame material conveying mechanism, the upper part of the steel strip material clamping frame is provided with an openable and closable steel strip material clamping mouth for clamping the steel strip material, the frame material clamping mouth can be pushed toward the end of the frame material conveying mechanism and can be turned toward the steel strip material clamping mouth, thereby, the frame material can be flexibly, efficiently and accurately turned and transported to various set positions of the steel strip material;

[0031] 2) The lifting frame in the frame material conveying mechanism can be raised and lowered and can slide back and forth, so that the feeding pins can shuttle (telescope) on the surface of the material placement plate repeatedly. The evenly arranged feeding pins can accurately position the frame material and drive the frame material to move, thereby achieving efficient feeding;

[0032] 3) A mounting base is provided on the working surface of the frame near the end of the frame material conveying mechanism. The mounting base can be slidably adjusted toward both sides of the frame material conveying mechanism. The frame material turning mechanism and the steel strip material clamping frame are mounted at different positions in front and behind the mounting base. In this way, the lateral position of the frame material turning mechanism and the steel strip material clamping frame relative to the frame material conveying mechanism can be flexibly adjusted.

[0033] 4) Since both the lifting frame and the mounting base can slide, the same sliding limit structure can be set on each sliding path to provide position limiting protection for the lifting frame and the mounting base respectively;

[0034] 5) The frame material turning mechanism controls the turning of the turning panel through a turning motor. The turning panel is also provided with a frame material clamping mechanism that can slide toward the frame material conveying mechanism. The frame material clamping mechanism controls the opening and closing of the frame material clamp formed by the upper and lower clamping plates through a jacking motor, and the lower clamping plate of the frame material clamp can slide back and forth relative to the turning panel. In this way, the frame material turning machine can not only realize turning but also flexibly adjust its position relative to the frame material conveying mechanism when opening and closing the upper and lower parts to clamp the frame material horizontally. This makes it possible that when the frame material is turned over, the distance between the frame material and the steel strip (i.e., the turning radius) can also be adjusted in time. It can be seen that the same mechanism contains multiple flexibly adjustable functions, with high flexibility and high precision.

[0035] 6) The limiting fence in the frame material limiting assembly can flexibly adjust the depth of the frame material extending into the frame material clamp, and further pre-adjust the upper and lower positions of the frame material relative to the steel strip after it is turned over;

[0036] 7) The crossbeam between the two sides of the steel strip clamping frame can increase the stability of the entire frame when sliding;

[0037] 8) The screw push assembly generates a relatively precise lateral movement force on the steel strip clamping frame to drive the frame material turning mechanism on the installation base to achieve high-precision synchronous side sliding adjustment;

[0038] 9) A steel strip material clamping mechanism is provided on the top of the steel strip material clamping frame. The steel strip material clamping mechanism forms a steel strip material rear clamping plate that can swing back and forth through a push-swing motor and a swing-pushing plate. A hook-shaped steel strip material clamping mouth is formed between the steel strip material front clamping plate and the steel strip material rear clamping plate, thereby horizontally clamping the steel strip material in the vertical direction;

[0039] 10) In order to further maintain the suspended horizontal stability of the entire long steel strip, a rolling clamping assembly and an elastic clamping assembly are respectively provided on both sides of the steel strip clamping frame. Among them, the rolling clamping assembly rolls and clamps the head and tail ends of the steel strip through the front and rear rollers, and the elastic clamping assembly elastically clamps the steel strip through the front and rear clamping blocks with springs for continuous support. In this way, the head and tail ends of the long steel strip can be effectively prevented from bending downward due to their own weight and becoming unstable. BRIEF DESCRIPTION OF THE DRAWINGS

A protective housing can also be provided on the horizontal working surface 101 to cover and protect the various mechanisms.

[0061] Combine Figures 3 to 5 As shown, the frame material conveying mechanism 1 includes a material placement plate 11, a lifting frame 12 and a feeding motor 13 arranged on the frame working surface 101.

The lifting feeding plate 10 is provided with a feeding plug 14 for passing through and exposed on the upper surface of the material placement plate 11. The output end of the feeding motor 13 is connected to the lifting frame 12 and then pushes and pulls the lifting frame 12 to slide back and forth toward the frame material turning mechanism 2, and drives the frame material 99 through the feeding plug 14.

[0062] like Figure 3 and Figure 4 As shown, the surface of the material placement plate 11 is provided with a plurality of grid grooves 110 which are connected vertically and parallel to each other. The grid grooves 110 extend toward the frame material turning mechanism 2 so as to allow the feeding plugs 14 to pass through accordingly.

[0063] like Figure 3 As shown, the upper surface of the material placement plate 11 is provided with multiple partitions 112 with adjustable spacing to separate the frame material 99. Specifically, support blocks 114 are provided on both sides of the material placement plate 11. A spacing adjustment rod 116 is inserted between the support blocks 114 on both sides.

[0066] Combine Figure 2 、 Figure 6 as well as Figure 12As shown, a mounting base plate 4 is provided on the frame working surface 101 near the end of the frame material conveying mechanism 1. Below the mounting base plate 4 are guide rails 40 extending toward both sides of the frame material conveying mechanism 1. The mounting base plate 4 slides on the guide rails 40. The frame material turning mechanism 2 and the steel strip material clamping frame 3 are mounted at different positions in front and behind the mounting base plate 4. Furthermore, the lateral position of the frame material turning mechanism 2 and the steel strip material clamping frame 3 relative to the frame material conveying mechanism 1 can be adjusted using the mounting base plate 4.

The other end of the pushing screw 44 extends out of the steel strip material clamping frame 3 and is rotatably connected to the pushing seat 46. Then, by rotating the pushing screw 44, the fixed sleeve 42 is forced to gradually screw into the pushing screw 44, thereby forcing the steel strip material clamping frame 3 to move adjustable.

The limit block group 31 is adjustably slidably provided on the adjustment frame beam 33 through the embedded groove. The limit block group 31 includes a back surface 310, a side surface 312, and a bottom surface 314. The back surface 310 of the limit block group 31 is directly limited on the front-back swing path of the swing push plate 78. The side surface 312 of the limit block group 31 is correspondingly limited on the side surface of the swing push plate 78. The bottom surface 314 of the limit block group 31 is correspondingly limited on the bottom end of the swing push plate 78. In this way, the swing of the rear clamping plate 76 of the steel strip is well protected by the swing limit.

[0077] Combine Figure 12 、 Figure 17 and Figure 18 As shown, rolling clamping assemblies 8 are respectively provided on both sides of the steel strip material clamping frame 3 for rolling and clamping the steel strip material 98 in the vertical direction. Specifically, the rolling clamping assembly 8 includes an extension plate 80, a front roller 82, and a rear roller 84. The extension plate 80 is mounted on the upper portion of the protective shell plate 6 and includes an extended mounting end extending toward the clamping line where the steel strip material clamping opening is located. The front roller 82 and the rear roller 84 are installed on the extended mounting end at intervals in front and back and each rotates around a vertical axis. The leading and trailing ends of the steel strip material 98 are respectively rollingly clamped between the front roller 82 and the rear roller 84.

[0078] At the same time, elastic clamping components 9 are respectively provided on both sides of the lower surface of the mounting top plate 30. The elastic clamping components 9 include a front clamping block 90 and a rear clamping block 92. The rear clamping block 92 is provided with an elastic telescopic surface 96 that is continuously supported by a spring component 94. The steel strip material 98 is elastically clamped between the elastic telescopic surface 96 and the front clamping block 90.

[0079] In this way, through the steel strip clamping mechanism 7, the rolling clamping assembly 8 and the elastic clamping assembly 9 on the same clamping line, it is ensured that all parts of the entire suspended long steel strip 98 can remain stable to avoid local instability.

[0080] After having the above structural features, combined Figure 2 、 Figure 3 、 Figures 17 to 19 As shown, the present invention can be implemented according to the following process:

[0081] a. Figure 2As shown, an end plate 17 is provided at the front end of the frame material conveying mechanism 1, and the frame material 99 is horizontally placed on the upper surface of the placement plate of the frame material conveying mechanism 1; and the mounting base 4 is adjusted to determine the lateral position of the frame material turning mechanism 2 and the steel strip material clamping frame 3 relative to the frame material conveying mechanism 1. The position is appropriate to ensure that each frame material 99 at the lateral position can enter the frame material clamping opening;

[0082] b. Figure 3 As shown, the feeding motor 13 and the lifting motor 122 are started, so that the feeding pin 14 passes through the upper surface of the placement plate. Since the frame material 99 itself has a number of frame holes, the feeding pin 14 can pass through these holes and drive the frame material 99 to move toward the end of the placement plate. When a group of frame materials 99 is transported to the end, the feeding pin 14 automatically descends, retracts from the upper surface of the placement plate, and returns to its initial position.

[0083] c. While transporting the frame material 99, Figures 17 and 18 As shown, the steel strip 98 can be horizontally clamped between the clamping mechanism 7, the elastic clamping assembly 9 and the rolling clamping assembly 8 of the clamping frame to keep the entire steel strip 98 stable;

[0084] d. Figure 19 As shown, after the frame material 99 is transported horizontally to the frame material turning mechanism 2, the distance between the frame material clamping mechanism 5 and the frame material transporting mechanism 1 is adjusted, and the lifting motor 58 is turned on to clamp the frame material 99 between the upper clamping plate 52 and the lower clamping plate 50;

[0085] e. Start the flip motor 20 and rotate the flip panel 24 45° first. If the vertical distance (flip radius) of the frame material 99 after flipping is not enough to hang on the steel strip material 98, it is necessary to start the pushing motor 56 of the frame material clamping mechanism 5 again to make the frame material clamping mechanism 5 further extend the flip panel 24 so that the frame material 99 can be hung on the lower edge of the steel strip after flipping. Then, rotate it another 45°. At this time, the frame material 99 is flipped to 90°, which is just enough to be accurately hung on the lower edge of the steel strip material 98, completing the established process; if before flipping, it is predicted that the flip radius of the frame material 99 is sufficient to reach the steel strip material 98, then directly flip the flip panel 24 90° without pausing to adjust the distance, so as to increase work efficiency.

[0086] The lead frame flipping and loading device for an automated production line provided by the present invention features a feeding mechanism that utilizes a reciprocating feed pin to achieve efficient positioning and feeding. The flipping mechanism not only flips the material but also adjusts the flipping radius, ensuring that the frame material reaches the lower edge of the large steel strip after flipping. The steel strip clamping mechanism ensures that the entire strip remains stable. Overall, the overall structural design of the lead frame loading device in this application is rational and sophisticated, taking into account all aspects of the loading process and providing comprehensive functionality.

[0087] The embodiments of the present invention are only used to illustrate the present invention and do not limit the scope of the claims. Other substantially equivalent alternatives that can be thought of by those skilled in the art are all within the scope of protection of the present invention.
