Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 3 As shown, the first aspect of the present invention provides a flat rectangular solder wire rolling and solder sheet cutting production device. Existing circular solder wires in the industry, after being processed by this rolling mechanism and passing through a specially designed rolling shaft device (using two L-shaped rolling settings) / (vertical L structure R angle = 0), can achieve a complete planar appearance of the solder wire, and the length of the solder sheet can be cut using a cutting device. The flat rectangular solder wire rolling and solder sheet cutting production device includes a shearing table 7, a solder wire spool hanging frame 101, a rolling mechanism 103, and a guide and limiting mechanism 102. The rolling mechanism 103 is installed on the shearing table 7, and the solder wire spool hanging frame 101 is arranged at intervals on the side of the rolling mechanism 103. The rolling mechanism 103 includes two rolling rollers, which are arranged to rotate relative to each other. L-shaped cavities are formed at the relative rolling positions of the two rolling rollers, and the L-shaped cavities of the two rolling rollers form a rectangular rolling cavity. The guide and limiting mechanism 102 is provided on the surface of the rolling mechanism 103 near the solder wire spool hanging frame 101. The solder wire spool hanging frame 101 has an L-shaped sheet structure.

[0022] The technical effects achieved by the above embodiments are as follows:

[0023] 1. By comparing the differences in production modes using mold casting, the generation of oxides when tin alloys are reheated to a liquid state can be reduced;

[0024] 2. By comparing the differences in stamping production modes, the complex process of tinplate production during stamping can be reduced, as well as the generation of excess waste during stamping.

[0025] 3. Reduce personnel requirements and workplace safety incidents during operation, and improve the dimensional stability, standardization, and consistency of solder sheet products;

[0026] 4. Improve the appearance of solder sheets that are not flat (arc, deformation) caused by mold casting and stamping in the existing production method, improve the stability of component placement during SMT equipment production; reduce the misjudgment of SMT equipment image recognition, and reduce air leakage and material ejection caused by SMT equipment nozzles not being able to fit flat.

[0027] Optional, such as Figures 1 to 3 As shown, in some embodiments, the top of the tin wire reel holder 101 is provided with a hanging hole.

[0028] Optional, such as Figures 1 to 3 As shown, in some embodiments, a control cabinet 100 is also included. The control cabinet 100 is provided on the side of the shearing table 7. The control cabinet 100 is located on the side of the rolling forming mechanism 103 away from the guide limiting mechanism 102.

[0029] Combination Figure 3 As shown, the shearing mechanism 4 includes a support block 41 and a shearing blade 42. The support block 41 is fixed to the table surface of the shearing table 7, and a feed groove is provided horizontally inside the support block 41 for horizontally feeding solder wire from left to right. The shearing blade 42 is electrically controlled and mounted on the right side of the support block 41, and the movement direction of the shearing blade 42 is vertical, so that after the shearing blade 42 runs, it is flat against the right side of the support block 41 and cuts the solder wire according to length. The shearing blade 42 is a single-blade cutter. In addition, the feeding mechanism 5 includes a drive roller 51 and a driven roller 52. Both the drive roller 51 and the driven roller 52 are vertically mounted on the table surface of the shearing table 7, and a gap is formed between the drive roller 51 and the driven roller 52 for horizontally feeding solder wire to the shearing mechanism 4. The drive roller 51 is connected to a servo motor drive. Using the servo motor drive, the feeding mechanism 5 can control the length of the formed solder wire that advances to the shearing mechanism 4, so as to batch produce solder sheets through the shearing mechanism 4. Optionally, such as Figures 1 to 3 As shown, in some embodiments, a tension wheel 71 is also included, which is provided between the control cabinet 100 and the feeding mechanism 5 on the side of the rectangular hole mold 3.

The guide mechanism 9 includes a guide wheel 91 and a guide block 92. The guide wheel 91 is rotatably connected to the table surface of the shearing table 7 and is located below the tension wheel 71. The solder wire passing through the tension wheel 71 passes around the guide wheel 91 and then advances horizontally to the feeding mechanism 5. The guide block 92 is installed on the table surface of the shearing table 7, and a guide groove is provided in the guide block 92 to allow the solder wire to be fed horizontally from left to right. A set of guide blocks 92 is provided between the feeding mechanism 5 and the guide wheel 91, and between the feeding mechanism 5 and the shearing mechanism 4, to ensure the stability of the horizontal advancement of the formed solder wire and to prevent it from easily scattering.

[0031] The operating principle of this device is as follows:

[0032] 1. Suspend the industry-standard round solder wire on the solder wire reel mounting bracket 101 of this equipment;

[0033] 2. Through physical changes, the guide limiting mechanism 102 and the rolling forming mechanism 103 shape the round solder wire into a rectangular (square) solder wire after the round solder wire is rolled and formed to the required width and thickness.

[0034] 3. The tension wheel 71 sends a feedback signal to the control cabinet 100 to adjust the operation control of the rolling mechanism to prevent the solder wire from scattering after forming.

[0035] 4. The formed solder wire is guided to the servo motor mechanism through the guide mechanism 9;

[0036] 5. The length of the solder wire after forming is transmitted and controlled through the servo motor mechanism of the feeding mechanism 5.
