[0050] The moving mechanism 500 is connected to the third connecting member 330. The moving mechanism 500 slides on the frame 100 to drive the first connecting member 310 to move above the conveying mechanism 200. The driving mechanism drives the sliding member 340 to move up and down, so that the first connecting member 310 can take away the product 810 on the conveying mechanism 200, so that the conveying mechanism 200 can provide the adjustment mechanism 300 with the product 810. Two rows of PIN pins are arranged on the product 810. The driving mechanism drives the first connecting member 310 to rotate around the first rotation axis so that the PIN pins of one row of the product 810 are lower than the PIN pins of the other row. The driving mechanism drives the first connecting member 310 to move above the tin furnace 900. The driving mechanism drives the sliding member 340 to slide up and down so that the PIN pins of one row of the product 810 on the first connecting member 310 are immersed in the tin liquid, so as to prevent the high temperature tin liquid from damaging the main body of the product 810 and improve the product 810. Yield; before the driving mechanism drives the PIN pins of the product 810 on the first connecting member 310 to separate from the tin liquid, the driving mechanism drives the second connecting member 320 to rotate around the second rotation axis. Since the product 810 of the first connecting member 310 rotates around the first rotation axis and the second rotation axis successively, when the driving mechanism drives the product 810 to separate from the tin liquid, a certain inclination angle is formed between the product 810 and the horizontal plane of the tin liquid, and the tin liquid between the PIN pins will be affected by the combined effect of gravity and the tension of the tin liquid, so that the excess tin liquid between the PIN pins sinks and flows back into the tin furnace 900, so as to reduce the phenomenon of tin connection between the PIN pins, thereby improving the yield of the product 810; when one row of PIN pins is completed with tinning, the driving component drives the first connecting member 310 to rotate around the first rotation axis again, so that the position of the row of PIN pins that have not completed tinning is lower than the position of the row of PIN pins that have completed tinning, and then repeats the above steps to complete the tinning of the other row of PIN pins.

[0073] Reference Figures 1 to 8 According to the tinning method of the second embodiment of the present application, applied to the tinning equipment of the first embodiment, the tinning method includes the following steps:

[0074] S10, conveying the product 810 to the bottom of the frame 100 through the conveying mechanism 200, and moving the third connecting member 330 through the moving mechanism 500 to drive the first connecting member 310 to move to the top of the conveying mechanism 200;

[0075] S20, driving the sliding member 340 to move downward through the driving mechanism to drive the first connecting member 310 to move downward, so as to adsorb the product 810 through the first connecting member 310;

[0076] S30, driving the sliding member 340 to move upwards through the driving mechanism;

[0077] S40, moving the third connecting member 330 through the moving mechanism 500 to drive the first connecting member 310 to move above the tin furnace 900;

[0078] S50, driving the first connecting member 310 to rotate around the first rotation axis by a driving mechanism, so that one row of PIN pins of the product 810 is higher than the other row of PIN pins;

[0079] S60, driving the sliding member 340 to move downward by the moving mechanism 500, so that one row of PIN pins of the product 810 is immersed in the tin liquid; specifically, the time for the product 810 to be immersed in the tin liquid is 1 to 2 seconds;

[0080] S70, driving the second connecting member 320 to rotate around the second rotation axis through the driving mechanism;

[0081] S80, driving the sliding member 340 to move upward by the driving mechanism, so that the PIN pin of the product 810 is separated from the tin liquid; specifically, the interval between step S70 and step S80 is 1 to 2 milliseconds;

[0082] S90, driving the first connecting member 310 to rotate around the first rotation axis by a driving mechanism, so that a row of PIN pins to be dipped in tin of the product 810 is lower than a row of PIN pins that have been dipped in tin;

[0083] S100, driving the sliding member 340 to move downward by the moving mechanism 500, so that a row of PIN pins to be tinned of the product 810 are immersed in the tin liquid; specifically, the time for the product 810 to be immersed in the tin liquid is 1 to 2 seconds;

[0084] S110, driving the second connecting member 320 to rotate around the second rotation axis through the driving mechanism;

[0085] S120, driving the sliding member 340 to move upward through the driving mechanism to separate the PIN pin of the product 810 from the tin liquid; specifically, the interval between step S110 and step S120 is 1 to 2 milliseconds.

[0086] The moving mechanism 500 is connected to the third connecting member 330. The moving mechanism 500 slides on the frame 100 to drive the first connecting member 310 to move above the conveying mechanism 200. The driving mechanism drives the sliding member 340 to move up and down, so that the first connecting member 310 can take away the product 810 on the conveying mechanism 200, so that the conveying mechanism 200 can provide the adjustment mechanism 300 with the product 810. Two rows of PIN pins are arranged on the product 810. The driving mechanism drives the first connecting member 310 to rotate around the first rotation axis so that the PIN pins of one row of the product 810 are lower than the PIN pins of the other row. The driving mechanism drives the first connecting member 310 to move above the tin furnace 900. The driving mechanism drives the sliding member 340 to slide up and down so that the PIN pins of one row of the product 810 on the first connecting member 310 are immersed in the tin liquid, so as to prevent the high temperature tin liquid from damaging the main body of the product 810 and improve the product 810. Yield; before the driving mechanism drives the PIN pins of the product 810 on the first connecting member 310 to separate from the tin liquid, the driving mechanism drives the second connecting member 320 to rotate around the second rotation axis. Since the product 810 of the first connecting member 310 rotates around the first rotation axis and the second rotation axis successively, when the driving mechanism drives the product 810 to separate from the tin liquid, a certain inclination angle is formed between the product 810 and the horizontal plane of the tin liquid, and the tin liquid between the PIN pins will be affected by the combined effect of gravity and the tension of the tin liquid, so that the excess tin liquid between the PIN pins sinks and flows back into the tin furnace 900, so as to reduce the phenomenon of tin connection between the PIN pins, thereby improving the yield of the product 810; when one row of PIN pins is completed with tinning, the driving component drives the first connecting member 310 to rotate around the first rotation axis again, so that the position of the row of PIN pins that have not completed tinning is lower than the position of the row of PIN pins that have completed tinning, and then repeats the above steps to complete the tinning of the other row of PIN pins.
