Description

Technical Field

[0001] The utility model relates to the technical field of soldering tin machines, in particular to a novel automatic soldering tin machine. Background Art

[0002] A soldering tin machine is a device used in the electronics manufacturing industry, mainly used for coating a tin layer on a circuit board. These machines are usually used to manufacture printed circuit boards (PCBs) or other electronic components. The working principle of a soldering tin machine is to immerse the circuit board into molten tin so that its surface is covered with a layer of tin, to improve the electrical conductivity of the circuit board and protect its surface from oxidation.

[0003] Tin melts into a liquid in the pool body. Frequent entry of circuit boards will cause impurities and dross to appear on the liquid surface. There is no scraping structure on the existing soldering tin machines. Impurities, dross, etc. floating on the liquid surface will affect the tin coating effect of the circuit board. Therefore, a novel automatic soldering tin machine is proposed. The scraper at the bottom of the connecting rod is driven to move by a reduction motor, a reciprocating lead screw and a second internally threaded slider, so as to scrape the impurities, dross, etc. on the surface of the tin liquid, so that it will not affect the tin coating effect of the circuit board. Summary of the Utility Model

[0004] Aiming at the problems in the prior art, the utility model provides a novel automatic soldering tin machine. The scraper at the bottom of the connecting rod is driven to move by a reduction motor, a reciprocating lead screw and a second internally threaded slider, so as to scrape the impurities, dross, etc. on the surface of the tin liquid, so that it will not affect the tin coating effect of the circuit board.

[0005] The technical solution adopted by the utility model to solve its technical problems is a novel automatic soldering tin machine, which includes a pool body. A heater is fixed at the bottom inside the pool body by bolts. A gantry is fixed at the top of the pool body by bolts. A driving component is arranged inside the gantry. The driving component includes a servo motor installed on one side of the gantry through a mounting frame and a lead screw rotatably connected inside the gantry through a bearing. A first internally threaded slider is sleeved outside the lead screw. An electric telescopic rod is installed at the bottom of the first internally threaded slider through a mounting frame.

[0006] A scraping component is arranged on one side of the pool body. The scraping component includes a box body fixed on one side of the pool body by bolts. A reciprocating lead screw is rotatably connected inside the box body through a bearing. A second internally threaded slider is sleeved outside the reciprocating lead screw. A connecting rod is fixed at the top of the second internally threaded slider by bolts. A scraper is fixed at the bottom of the connecting rod located inside the pool body by bolts. A reduction motor is installed inside the box body at the bottom of the reciprocating lead screw through a mounting frame.

[0007] By adopting the above technical solution, the servo motor drives the circuit board to move through the lead screw and the first internal thread slider. The electric telescopic rod pushes the fixture and the circuit board fixed inside it downward, immersing the circuit board into the tin liquid. The reduction motor drives the scraper at the bottom of the connecting rod to move through the reciprocating lead screw and the reciprocating lead screw, and can scrape the impurities, tin dross, etc. on the surface of the tin liquid to both sides.

[0008] Specifically, a first gear is fixedly sleeved on one side of the reduction motor through a flat key, and a second gear is fixedly sleeved on the outer end of the reciprocating lead screw. The second gear meshes with the first gear.

[0009] Specifically, a second auxiliary rod is fixedly installed inside the top of the reciprocating lead screw of the box body through bolts, and the second auxiliary rod penetrates through the second internal thread slider.

[0010] Specifically, a thermostat is installed at one end of the pool body through a mounting seat. The detection end of the thermostat is located inside the pool body, and the current output end of the thermostat is electrically connected to the current input end of the heater through a power cord.

[0011] Specifically, one side output shaft of the servo motor is fixedly connected to one end of the lead screw through a connecting sleeve. A first auxiliary rod is fixedly installed inside the top of the gantry through bolts, and the first auxiliary rod penetrates through the first internal thread slider.

[0012] Specifically, the bottom output shaft of the electric telescopic rod is fixedly connected to a fixture through bolts.

[0013] The beneficial effects of the present utility model:

[0014] (1) For a new type of automatic tin dipping machine of the present utility model, when the servo motor is turned on to drive the lead screw to rotate, the lead screw rotates to push the first internal thread slider to move. The first internal thread slider moves to drive the circuit board fixed on the fixture through the electric telescopic rod. When the electric telescopic rod is turned on to push the fixture downward, the bottom of the circuit board fixed inside it is immersed in the tin liquid for tin dipping operation.

[0015] (2) For a new type of automatic tin dipping machine of the present utility model, when the reduction motor is turned on, it drives the reciprocating lead screw to rotate through the first gear and the second gear. The reciprocating lead screw rotates to push the second internal thread slider and the connecting rod on its top to reciprocate. The connecting rod reciprocates to scrape the impurities, tin dross, etc. on the surface of the tin liquid through the scraper at the bottom, and pushes the impurities, tin dross, etc. to both sides to prevent them from affecting the tin dipping of the circuit board.
