[0002] In the electronics manufacturing industry, lead-free solder foil is widely used in the packaging and connection of various electronic products due to its environmental friendliness and high-temperature resistance. Traditional lead-free solder foil stamping devices mostly use simple mechanical structures, such as a pneumatic or hydraulic cylinder directly driving a punch head to move up and down to stamp the lead-free solder foil. However, these devices have encountered numerous technical issues during long-term use.

[0003] First, traditional stamping devices often lack sufficient stability and guidance during the lifting and lowering process, resulting in an inaccurate trajectory of the punch head, which in turn affects the accuracy and efficiency of stamping. Second, the position of the side guide rollers is usually fixed and cannot be flexibly adjusted to the width of the lead-free tin sheet, limiting the applicability and flexibility of the equipment. Furthermore, traditional stamping devices often lack effective shock absorption and buffering measures during the stamping process, making the machine and stamping mechanism susceptible to impact and damage, reducing the equipment's service life.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0023] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0025] Combined with attachment Figure 1 -Attached Figure 3 A lead-free tin sheet stamping device includes a machine platform 1, a mounting frame 2 is provided on the machine platform 1, a lifting seat 3 that can be lifted and lowered reciprocatingly is provided on the mounting frame 2, an upper punch 4 is provided at the lower end of the lifting seat 3, and a lower die base 5 corresponding to the position of the upper punch 4 is also provided on the machine platform 1. Two side guide rollers 6 with adjustable distances are provided at the front and rear of the lower die base 5.

[0026] In one embodiment, guide blocks 7 are provided on both inner sidewalls of the mounting frame 2, and guide blocks 8 are provided on both sides of the lifting frame 3 to slide with the guide blocks 7. A crankshaft 9 is also rotatably mounted on the mounting frame 2. The curved portion of the crankshaft 9 is rotatably encased in a swing arm 10, the bottom of which is rotatably connected to the upper end of the lifting frame 3. In this embodiment, the guide blocks 7 are cleverly arranged on both inner sidewalls of the mounting frame 2, providing a solid foundation for the smooth movement of the lifting frame 3. The sides of the lifting frame 3 are slidably engaged with the guide blocks 7 via precision-machined guide blocks 8. This design not only ensures the stability of the lifting frame 3 during the lifting process but also significantly reduces friction and wear. Furthermore, a crankshaft 9 is also rotatably mounted on the mounting frame 2. The curved portion of the crankshaft 9 is cleverly rotatably encased in a swing arm 10, the bottom of which is rotatably connected to the upper end of the lifting frame 3. This ingenious mechanical design allows the rotation of the crankshaft 9 to efficiently convert the reciprocating lifting motion of the lifting frame 3, providing a stable and reliable power source for subsequent stamping operations.

[0027] In one embodiment, a drive motor 11 is mounted on the mounting frame 2. The output shaft of the drive motor 11 is equipped with a driving gear 12. One end of the crankshaft 9 is provided with a driven gear 13 that meshes with the driving gear 12. When the drive motor 11 is started, its output shaft rotates the driving gear 12, which in turn, through the precise meshing between the gears, drives the driven gear 13 and the crankshaft 9 to rotate. This power transmission method is not only efficient but also stable, providing a continuous source of power for subsequent lifting and stamping operations.

[0028] In one embodiment, mounting seats 14 are provided at the front and rear sides of the lower die base 5. Mounting seats 14 are provided with mounting slots 15. A bidirectional screw 16 is rotatably mounted within the mounting slots 15. A handle 17 is provided at the outer end of the bidirectional screw 16. The bidirectional screw 16 is provided with two threaded portions with opposite thread directions. Both threaded portions are threadedly connected to an adjustment seat 18 that slidably cooperates with the mounting slots 15. The side guide rollers 6 are rotatably mounted on the adjustment seat 18 via mounting shafts. This design allows the operator to easily adjust the rotation of the bidirectional screw 16 by turning the handle 17, thereby driving the adjustment seat 18 and the side guide rollers 6 to flexibly move in the horizontal direction to accommodate strips of lead-free tin sheets of different widths, ensuring the accuracy and stability of the stamping process.

[0029] In one embodiment, support rollers 19 are provided at the front and rear of the lower die base 5 via a support frame 24. A lifting frame 23 is slidably mounted on the support frame 24, and an upper pressure roller 20 is mounted on the lifting frame 23. This design allows the operator to adjust the height of the lifting frame 23, thereby adjusting the gap between the upper pressure roller 20 and the support roller 19, to accommodate lead-free tin strips of varying thicknesses. Furthermore, an adjustment screw 25 is threadedly connected to the support frame 24, the bottom end of which is rotatably connected to the lifting frame 23. This adjustment method is not only simple and convenient, but also ensures the stability and accuracy of the upper pressure roller 20 during adjustment.

[0030] In one embodiment, the machine 1 is further provided with a guide post 21, onto which the lift seat 3 is slidably mounted. A buffer spring 22 is also mounted on the guide post 21, positioned between the lift seat 3 and the machine 1. This design not only provides precise guidance for the lifting motion of the lift seat 3 but also significantly enhances its stability. Furthermore, the buffer spring 22 is mounted on the guide post 21, positioned between the lift seat 3 and the machine 1. This buffer spring 22 acts as a shock absorber when the lift seat 3 descends, effectively protecting the machine 1 and the lifting mechanism from impact and damage. This design not only improves the durability of the entire stamping device but also ensures its stability and reliability during extended operation.

[0031] Working principle: First, the strip of lead-free tin to be stamped (not shown) is introduced onto the lower die base 5 via a traction device. Subsequently, the drive motor 11 is started, and its output shaft drives the driving gear 12 to rotate. The driving gear 12 engages with the driven gear 13, driving the crankshaft 9 to rotate. The rotation of the crankshaft 9 is converted into a reciprocating lifting motion of the lifting base 3 under the sliding cooperation of the guide base 7 and the guide block 8 through the swing arm 10. When the lifting base 3 descends, the upper punch 4 at its upper end continuously stamps the conveyed strip of lead-free tin. At the same time, the tin sheet is smoothly conveyed between the support roller 19 and the upper pressure roller 20, whose height can be adjusted by the adjusting screw 25, and is precisely guided by the side guide roller 6 (whose position can be adjusted by rotating the adjustment seat 18 on the bidirectional screw 16). In addition, when the lifting base 3 slides on the guide column 21, the buffer spring 22 acts as a shock absorber to protect the machine 1 and the lifting mechanism from impact. Through the coordinated action of the above components, the device achieves continuous and precise stamping of strip-shaped lead-free tin sheets and exhibits good adaptability and durability.

[0032] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
