[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] like Figure 1-2 As shown, an efficient desoldering equipment for motors and circuit boards includes a base 1 and a product fixing table 2. The product fixing table 2 is fixedly installed on the base 1. The products to be desoldered are a motor 8 and a circuit board 9 welded together. When desoldering is required, the motor 8 is inserted into the fixed slot 21 of the product fixing table 2.

[0028] The motor 8 and circuit board 9 are desoldered using the high-temperature solder melted by the welding gun 3. The molten solder is removed by the solder wick 4 during desoldering. By pre-adjusting the relative position of the welding gun 3 and the product, subsequent workers only need to pick up and place the product, without having to adjust the position of the product and welding gun 3 during the desoldering process. This prevents damage to the motor 8 pins due to manual movement during desoldering. Specifically, the position adjustment of the welding gun 3 and the solder wick 4 is achieved by the following method:

[0029] The desoldering equipment includes an intermediate connecting seat 5 slidably connected to the base 1 and a mounting member 6 slidably connected to the intermediate connecting seat 5. The welding gun 3 and the desoldering member 4 are both mounted on the mounting member 6. The welding gun 3 is mounted on a height adjustment frame 62, and the desoldering member 4 is mounted on a bracket 61. The height adjustment frame 62 can be a combination of a rotary locking structure and a support frame. The rotary locking structure clamps and mounts the welding gun 3.

[0030] The intermediate connecting seat 5 moves left and right relative to the product fixing platform 2, and the mounting bracket 6 moves forward and backward relative to the product fixing platform 2. By moving the intermediate connecting seat 5, the position of the welding gun 3 and the tin-absorbing component 4 relative to the product in the left-right direction is adjusted. By moving the mounting bracket 6, the position of the welding gun 3 and the tin-absorbing component 4 relative to the product in the front-back direction is adjusted. Then, by adjusting the height adjustment bracket 62, the position of the welding end of the welding gun 3 is adjusted in the height direction. As a result, the welding gun 3 can be freely adjusted in all dimensions, so that it can be positioned and fixed in advance to the position where the product needs to be desoldered. There is no need to manually hold the welding gun 3, which avoids damage to the product. Specifically, the base 1 is provided with a T-slot 11, and the intermediate connecting seat 5 is provided with a T-slot 11. The intermediate connecting seat 5 is provided with a T-slot 2 52, and the mounting bracket 6 is provided with a T-slot 2 62 that is compatible with the T-slot 2 52. In addition, the intermediate connecting seat 5 and the mounting bracket 6 can also be automatically shifted and positioned through manual screw adjustment or semi-automatic electric drive.

[0031] In order to completely remove tin from the tin-absorbing component 4 without any residue, in this embodiment, the tin-absorbing component 4 includes a tin-absorbing tape 41, a winding motor 44, a reel 42 for winding the tin-absorbing tape 41 that has not been tin-absorbing, and a reel 43 for winding the tin-absorbing tape 41 that has been tin-absorbing. The reel 42 and the reel 43 are both rotatably connected to the mounting frame 6, and the reel 42 and the reel 43 are driven to rotate by the winding motor 44.

[0032] During use, one end of the tin-absorbing tape 41 between the unwinding reel 42 and the winding reel 43 abuts the welding end of the welding gun 3, and the other end contacts the desoldering area of ​​the product. The winding motor 44 drives the unwinding reel 42 or the winding reel 43 to rotate. After one rotates, the other is indirectly driven to rotate by the tin-absorbing tape 41 wound thereon, thereby realizing automatic rewinding of the tin-absorbing tape 41 before and after use, reducing manual operation. The tin-absorbing tape 41 continuously absorbs tin in real time to avoid solder residue and ensure smooth desoldering. In addition, after the welding end of the welding gun 3 abuts the tin-absorbing tape 41, it can drive the tin-absorbing tape 41 to move in the height direction, so that the tin-absorbing tape 41 corresponds to the desoldering position of the product.

[0033] like Figure 3As shown, to enhance the tin-absorbing effect of the tin-absorbing ribbon 41 and ensure it adheres closely to the welding end of the welding gun 3, the tin-absorbing component 4 includes a tensioning structure 45 for tightening the tin-absorbing ribbon 41 between the unwinding reel 42 and the rewinding reel 43. The tensioning structure 45 includes a plurality of winding posts 451 mounted on the mounting component 6, around which the tin-absorbing ribbon 41 is wound. After being wound, the tin-absorbing ribbon 41 is automatically tightened, closely adhering to the welding end of the welding gun 3.

[0034] The desoldering equipment includes an intelligent controller 7, which is electrically connected to the winding motor 44 and the welding gun 3 and is used to drive or shut down the winding motor 44 and set the temperature of the welding gun 3. The intelligent controller 7 may include key components such as a microprocessor or controller unit, a temperature sensor, a motor drive circuit, a heating element control interface, a display and buttons, safety protection components, a communication interface, and a power supply and filter circuit. As these components are known in the art, they will not be described in detail here.

[0035] The product mounting platform 2 has a mounting slot 21 for the motor 8. The platform 2 includes a plurality of elastic legs 22 surrounding the mounting slot 21. The extended ends of the elastic legs 22 abut against the motor 8 to secure it. The mounting slot 21 and the elastic legs 22 are designed to prevent the product from shifting during the desoldering process and damaging the pins of the motor 8.

[0036] In addition, according to actual desoldering requirements, a set of desoldering equipment as described above can be installed on both sides of the product fixing table 2 to improve the desoldering efficiency.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
