When the end of the copper wire 2 passes through the inside of the liquid accumulating groove 29, the end of the copper wire 2 can be evenly attached to the tin solution.

[0035] The side end of the support side plate 8 facing away from the first bracket 10 is connected to the side end of the support shaft 23 facing away from the second gear 18, the displacement cross plate 20 is threadedly sleeved on the outer ring of the screw rod 34, the copper wire 2 is placed between the second bracket 11 and the first bracket 10, the two ends of the displacement cross plate 20 are slidably inserted into the inside of the movable groove 32, the bottom end of the roller 21 is in contact with the top surface of the support base 31, the second bracket 11 and the first bracket 10 are equidistantly provided with arc grooves on the opposite sides, and the inner wall of the arc groove is installed with a plastic sheet, the material of the support side plate 8 is iron, and the side end surface of the support side plate 8 facing away from the first bracket 10 is flush with the side end of the magnetic plate 22 facing away from the second gear 18, and the photoelectric sensor The device 26 is electrically connected to the fan 25, a vertical movable groove is provided inside the supporting vertical frame 19, and the H-shaped sliding key 17 is located inside the vertical movable groove, a threaded hole is provided inside the displacement cross plate 20, and the top and bottom ends of the displacement cross plate 20 are respectively fitted with the top and bottom ends of the inner part of the movable groove 32, the end surface of the guide base 27 close to the second rack 28 is inclined at 45°, the two ends of the inner part of the liquid accumulation groove 29 are inclined at 45°, and a partition plate is installed in the area adjacent to the liquid accumulation groove 29 and the guide groove 35, the fan 25 is vertically aligned with the displacement cross plate 20, the second gear 18 is vertically aligned with the second rack 28, and the first gear 13 is vertically aligned with the first rack 3.

[0036] The working principle of embodiment 1 is as follows: when in use, the counterweight 9 can be moved vertically downward by keeping the displacement cross plate 20 at the front end, and the first gear 13 can be moved to the limit position along the first rack 3 at the front end of the top of the support base 31, and the second bracket 11 can be spaced apart from the first bracket 10. The user can put the copper wire 2 into the arc groove on the first bracket 10 in sequence, and then start the driving motor 33 to drive the screw rod 34 to rotate clockwise, and the displacement cross plate 20 is threadedly sleeved on the screw rod 34, so that the screw rod 34 can drive the displacement cross plate 20 to move toward the rear end when it rotates clockwise. At this time, when the second bracket 11 moves along the bottom end of the first rack 3, it can drive the first gear 13 to rotate again, so that the winding wheel 14 can release the connecting rope 39. The elasticity of the reset spring 16 will drive the second bracket 11 to reset, so that the second bracket 11 can squeeze the copper wire 2 and tighten it with the first bracket 10. Plastic sheets are installed in the arc grooves on the inner sides of the first bracket 10 and the second bracket 11 to prevent the copper wire 2 from sliding and falling off. Subsequently, when the displacement cross plate 20 continues to move toward the rear end, it can drive the roller 21 to move toward the rear end along the top of the guide base 27. When the roller 21 slides along the bottom end of the guide base 27 to the top of the support base 31, the bottom end of the second gear 18 can be flush with the top end of the second rack 28. The H-shaped sliding key 17 is displaced in the vertical movable groove inside the support vertical frame 19, so that the gantry bracket 24 can be guaranteed to move in a straight line. Moreover, when the gantry bracket 24 moves downward, When moving, the H-shaped sliding key 17 can be driven to contact the photoelectric sensor 26, thereby triggering the photoelectric sensor 26 to start the fan 25. When the displacement cross plate 20 continues to move toward the rear end, the second gear 18 can be driven to move along the second rack 28, so that the support shaft 23 can drive the supporting side plate 8 to rotate, so that the two ends of the first rack 3 can pass through the tin solution inside the liquid accumulation tank 29 respectively, and complete the work of uniformly tinning the two ends of the copper wire 2. In addition, when the copper wire 2 with the tin solution attached is rotated to align with the fan 25, the fan 25 can be set to dry it naturally, so that the tin solution can quickly solidify and be adsorbed on the surface of the copper wire 2. When the roller 21 moves to the guide base 27 at the rear end of the top of the support base 31 and contacts it, the roller 21 can move along the guide base The slope surface of 27 moves upward, thereby preventing the copper wire 2 from contacting the surface of the support base 31. At the same time, when the second gear 18 passes the top of the second rack 28, the counterweight 9 will naturally move vertically downward, so that the copper wire 2 can be placed in a horizontal state. At the same time, when the counterweight 9 is vertically downward, the supporting side plate 8 and the magnetic plate 22 are adsorbed and fitted, so that the counterweight 9 can be prevented from shaking for a long time. Subsequently, when the displacement cross plate 20 drives the roller 21 to move backward to the top of the guide base 27 at the rear end of the top of the support base 31, the first gear 13 can be horizontally aligned with the first rack 3 at the rear end of the top of the support base 31, so that when the displacement cross plate 20 moves to the rear end, it can drive the first gear 13 to move to the first rack 3 at the rear end of the top of the support base 31 and contact.The winding wheel 14 can again pull the second bracket 11 away from the first bracket 10 through the connecting rope 39. At the same time, the second bracket 11 and the first bracket 10 can move to the top of the guide groove 35. When the second bracket 11 is out of contact with the first bracket 10, the copper wire 2 will fall into the inside of the guide groove 35, so that the copper wire 2 can slide and be discharged along the inside of the guide groove 35, completing the work of uniformly tinning and discharging the copper wire 2. When the device is in use, when the roller 21 moves to the top of the guide base 27, the H-shaped sliding key 17 can be out of contact with the photoelectric sensor 26, so that the fan 25 can be prevented from working for a long time and the waste of electric energy can be reduced. At the same time, when the second bracket 11 is moved, the copper wire 2 can be brought The movable guide rod 15 slides inside the supporting wing plate 12, so that the second bracket 11 can be supported to move in a straight line, and the docking accuracy of the second bracket 11 and the first bracket 10 is improved. Moreover, through the setting of the counterweight block 9 and the magnetic plate 22, the copper wire 2 can be driven to be placed in a horizontal state when the second gear 18 passes over the second rack 28, so as to avoid the copper wire 2 from contacting the surface of the supporting base 31. Moreover, the two ends of the liquid accumulating groove 29 are set at a 45° inclination, so that the copper wire 2 can be prevented from rubbing against the supporting base 31 when rotating. At the same time, a partition plate is installed in the area adjacent to the guide groove 35 and the liquid accumulating groove 29, so as to avoid the copper wire 2 from falling down into the inside of the liquid accumulating groove 29, and the work is completed.

[0037] Example 2

[0038] On the basis of Example 1, Figure 8 As shown, the support base 31 also includes an auxiliary positioning frame 36, a guide seat 37 and an extended top frame 38. The extended top frame 38 is fixedly mounted on the front end top of the support base 31, the guide seat 37 is fixedly mounted on the top of the extended top frame 38, and the auxiliary positioning frame 36 is fixedly mounted on the top rear end of the guide seat 37. Arc grooves are equidistantly provided at the bottom end of the auxiliary positioning frame 36 and the top end of the guide seat 37, and the arc grooves on the auxiliary positioning frame 36 and the guide seat 37 are aligned with the arc grooves in the first card frame 10 and the second card frame 11.

[0039] When implementing this embodiment, the unprocessed copper wire 2 can be placed in the arc groove between the guide seat 37 and the auxiliary positioning frame 36. The auxiliary positioning frame 36 is located above the guide seat 37, so that the copper wire 2 can be prevented from falling off on the guide seat 37. In addition, the guide seat 37 is horizontally aligned with the first bracket 10 that rises to the limit position, so that when the displacement cross plate 20 moves to the limit position toward the front end, it is convenient to align the first bracket 10 with the guide seat 37, and it is convenient to insert the copper wire 2 into the first bracket 10 to complete the work.
