[0002] The circuit board is the core carrier of modern electronic devices. It realizes the electrical connection and mechanical fixation of electronic components through copper foil traces on an insulating substrate, and at the same time undertakes the functions of signal transmission, power distribution and electromagnetic shielding. It is widely used in the fields of electronics, industrial control, automotive electronics, medical and aerospace.

[0003] Currently, during the production and processing of circuit boards, components such as resistors, capacitors, diodes, and rectifier bridges are soldered onto the circuit board. To facilitate operation and soldering, soldering is performed on soldering machines or platforms. Existing circuit board soldering machines lack rotation and fume extraction mechanisms, cannot drive the circuit board to rotate for easy operation, and cannot extract the fumes generated during soldering to prevent them from affecting the soldering process. Therefore, a circuit board soldering machine is proposed, which uses a drive motor to rotate the soldering station and the circuit board on top, facilitating operation. An exhaust fan can remove the fumes generated during soldering to prevent them from affecting the soldering process. Utility Model Content

The machine uses a drive motor to rotate the soldering station and the circuit board on top, which is convenient for personnel to operate.

[0007] By adopting the above technical solution, the drive motor drives the soldering station and the circuit board placed on top of it to rotate, adjusts the angle of the circuit board, the exhaust fan works to remove the fumes generated during soldering, and the LED beads work to emit bright light.

[0009] Specifically, the top of the welding station is glued with an anti-slip pad, and the protective cover is provided with through holes at equal intervals on the top of the outer side of the sleeve.

[0010] Specifically, the top of the protective cover is provided with a telescopic component, which includes a sleeve fixed to the top of the protective cover by a flange, a support rod sleeved at the top of the sleeve, a top plate rotatably connected to the top of the support rod by a bearing, and the cylinder body fixed to one end of the top plate by bolts.

[0011] Specifically, the two ends of one side of the sleeve are connected to fixing bolts through threaded grooves, and the support rod has equidistant through holes corresponding to the fixing bolts.

[0012] Specifically, a dustproof net is fixed to the top of the cylinder body with bolts, and an annular dustproof net is fixed to the bottom of the cylinder body located outside the structural cover with bolts.

[0013] The beneficial effects of this utility model are:

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The soldering station and its top circuit board are rotated by a drive motor, facilitating operation. An exhaust fan removes fumes generated during soldering, preventing them from interfering with the soldering process. Figure 1-4 As shown, the circuit board soldering machine of this utility model includes a base 1. A column 7 is rotatably connected inside the base 1 through a bearing. A soldering station 2 is fixed to the top of the column 7 at the top of the base 1 through a flange. A protective cover 3 is fixed to the top of the base 1 on one side of the soldering station 2 through bolts. A drive motor 9 is installed inside the protective cover 3 through a mounting bracket.

[0024] The base 1 has a cylindrical body 4 on top. An exhaust fan 13 is installed inside the cylindrical body 4 via a mounting bracket. A structural cover 16 is installed at the bottom of the cylindrical body 4 via a mounting bracket. An LED bead 17 is fixed to the top of the structural cover 16 via bolts. A transparent protective plate 18 is fixed inside the structural cover 16 at the bottom of the LED bead 17 via a slot.

[0025] When in use, the drive motor 9 drives the soldering station 2 and the circuit board placed on top of it to rotate. Adjusting the angle of the circuit board causes the exhaust fan 13 to work and remove the fumes generated during soldering. The LED beads 17 work to emit bright light.

[0026] For example, such as Figure 2 As shown, the present invention also includes a first synchronous wheel 10 fixedly sleeved on the outer side of the column 7 located inside the base 1 by a fixed key, and a second synchronous wheel 11 fixedly sleeved on the output shaft of the drive motor 9 located inside the base 1 by a fixed key. A synchronous belt 12 is sleeved on the outer side of the second synchronous wheel 11 and the first synchronous wheel 10.

[0027] In use, the drive motor 9 drives the column 7 to rotate through the second synchronous pulley 11, the synchronous belt 12 and the first synchronous pulley 10.

[0028] For example, such as Figure 2 As shown, the present invention also includes an anti-slip pad 8 glued to the top of the welding station 2, and through holes 19 equidistantly opened on the top of the protective cover 3 located outside the sleeve 501.

[0029] During use, the anti-slip pad 8 prevents the circuit board placed on the soldering station 2 from shifting, and the through hole 19 facilitates heat dissipation of the drive motor 9.

[0030] For example, such as Figure 1 , Figure 4 As shown, the present invention also includes a telescopic component 5 provided on the top of the protective cover 3. The telescopic component 5 includes a sleeve 501 fixed to the top of the protective cover 3 by a flange. A support rod 502 is sleeved on the top of the sleeve 501. The top of the support rod 502 is rotatably connected to a top plate 6 by a bearing. The cylinder 4 is fixed to one end of the top plate 6 by bolts.

[0031] When in use, the support rod 502 is sleeved on the top of the sleeve 501 and can move up and down to facilitate adjustment of the height of the cylinder 4.

[0032] For example, such as Figure 4 As shown, the present invention also includes a fixing bolt 503 connected to both ends of one side of the sleeve 501 through a threaded groove, and a retaining hole 504 corresponding to the fixing bolt 503 is provided through one side of the support rod 502 at equal intervals.

[0033] When in use, tighten the fixing bolt 503 so that one end is inserted into the corresponding clip hole 504 to fix the telescopic support rod 502.

[0034] For example, such as Figure 3 As shown, the present invention also includes a dustproof net 14 fixed to the top of the inner cavity 4 by bolts, and an annular dustproof net 15 fixed to the bottom of the inner cavity 4 located outside the structural cover 16 by bolts.

[0035] When in use, the installation of the annular dustproof net 15 and the dustproof net 14 can prevent dust and other particles from entering the cylinder 4 with the airflow.

[0036] When using this utility model, the user connects the device to an external power source using a power cord, places the circuit board on the soldering station 2 for soldering, and the top of the soldering station 2 is glued with an anti-slip pad 8 to prevent the circuit board placed on the soldering station 2 from shifting.

[0037] When the drive motor 9 is turned on, it drives the column 7 and the soldering station 2 on top of it to rotate through the second synchronous pulley 11, the first synchronous pulley 10 and the synchronous belt 12. This can drive the circuit board placed on the soldering station 2 to rotate, making it easy to adjust the angle of the circuit board and make it convenient for personnel to solder components such as resistors, capacitors, diodes, and rectifier bridges onto the circuit board.

[0038] Turn on the exhaust fan 13 inside the cylinder 4. The fumes generated during soldering can be drawn into the cylinder 4 through the annular dustproof net 15 and discharged through the dustproof net 14 at the top of the cylinder 4, so as to avoid the fumes generated during soldering affecting personnel operations.

[0039] Turning on the LED bead 17 can emit bright light to illuminate the circuit board, making it convenient for personnel to perform soldering. The support rod 502 is sleeved on the top of the sleeve 501 and can move up and down to adjust the height of the cylinder 4. Tightening the fixing bolt 503 so that one end is inserted into the corresponding clip hole 504 can fix the support rod 502 after it has moved up and down.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
