[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] See also Figure 1-4 The utility model provides an embodiment: a fan circuit board whole board soldering device, including a base plate 1, a rear vertical plate is fixedly installed on one side of the upper surface of the base plate 1, an upper vertical plate 3 is fixedly installed on the top outer wall of the rear vertical plate, a first-level slide 7 is provided on the front exterior of the upper vertical plate 3, an upper mounting plate 8 is fixedly installed on the outer surface of the first-level slide 7, a first-level cylinder 9 is fixedly installed on the outer side of the upper mounting plate 8 by bolts, an output end of the first-level cylinder 9 is telescopically connected to a pneumatic rod 10, and a lower mounting plate 11 is fixedly installed on the bottom end of the pneumatic rod 10;

[0026] Among them, the upper mounting plate 8 adopts an "L"-shaped structural design, and the lower mounting plate 11 adopts an inverted "L"-shaped structural design;

[0027] The outer surface of the lower mounting plate 11 is rotatably mounted with a secondary screw 12 on both sides through a bearing seat. The secondary screw 12 is a forward and reverse threaded screw. One end of the secondary screw 12 is fixedly connected to the output shaft of the secondary motor 13. The forward and reverse threads of the secondary screw 12 are both threadedly connected to a threaded seat 14. The bottom end of the threaded seat 14 is fixedly mounted with a mounting post 15. The bottom end of the mounting post 15 is fixedly mounted with a soldering head 16. The soldering head 16 can heat the soldering when working.

[0028] A rotating seat 17 is fixedly mounted on the outer wall of the front face of the mounting column 15. A rotating plate 18 is rotatably connected to the rotating seat 17 via a damping shaft. A tinning head 19 is fixedly mounted on the lower surface of the bottom end of the rotating plate 18. When the tinning head 19 is actually in use, the solder wire can be inserted into the tinning head 19, thereby tinning the solder wire through the tinning head 19, making it easier to solder the circuit board.

[0029] The direction of the head of the tin inlet head 19 can be adjusted by rotating the rotating plate 18, so that the angle of the tin wire spitting direction of the tin inlet head 19 can be effectively adjusted freely to ensure that the tin wire outlet of the tin inlet head 19 is always facing the solder head 16;

[0030] According to the above structure, when the present invention is in use, the first-stage cylinder 9 is provided to drive the pneumatic rod 10 to extend. When the pneumatic rod 10 extends, it will simultaneously drive the lower mounting plate 11 at the tail end to descend as a whole. The overall descending of the lower mounting plate 11 can drive the soldering heads 16 on both sides to descend, so that the descending soldering heads 16 can contact the circuit board of the cooling fan, completing the free movement effect of the soldering heads 16 in the Z-axis direction.

[0031] At the same time, during the descending process, the tin feeding head 19 works to spit out tin. When the soldering head 16 contacts the circuit board of the cooling fan, the spitted tin wire can be heated by the soldering head 16 to solder the circuit board of the cooling fan, thereby completing the soldering process of the circuit board of the cooling fan;

[0032] The utility model adopts the structural design of double soldering heads. In actual use, in a single soldering operation, the soldering work of two areas can be completed, thereby effectively improving the soldering efficiency of the circuit board and increasing the overall soldering speed. Compared with traditional soldering equipment, the utility model can effectively increase the processing efficiency by two times, save half the processing time, and has the characteristics of fast soldering processing.

[0033] The present invention is provided with a secondary motor 13, which can drive the secondary screw 12 to rotate. Since the secondary screw 12 is a forward and reverse threaded rod, when the secondary screw 12 rotates, the two threaded seats 14 thereon will move relative to each other, that is, move away from or approach each other. In this way, the relative movement of the two threaded seats 14 can drive the two sets of soldering heads 16 to move, thereby achieving the purpose of adjusting the distance between the two soldering heads 16.

[0034] In actual use, by adjusting the distance between the two soldering heads 16, it is possible to perform soldering processing on soldering areas at different distances of the circuit board, which greatly improves the use effect of the utility model, reduces the limitations of use, and has the characteristic of dynamically adjustable soldering point distance, which is more practical.

[0035] In this embodiment, in order to drive the primary slide 7 and the soldering head 16 thereunder to perform left and right linear displacement and meet the effect of free movement of the two soldering heads 16 in the X-axis direction, primary guide rails 4 are fixedly installed on both sides of the outer surface of the upper vertical plate 3. A primary screw 5 is rotatably installed between the two primary guide rails 4 and on the outer surface of the upper vertical plate 3 through a bearing seat. One end of the primary screw 5 is fixedly connected to the output shaft of the primary motor 6.

[0036] Among them, the first-level slide 7 is sleeved on the outside of the first-level screw 5, and the first-level slide 7 is threadedly connected to the first-level screw 5, and both sides of the first-level slide 7 are slidably connected to the first-level guide rail 4;

[0037] This structural design can be rotated by the set first-level motor 6, and the output shaft of the first-level motor 6 can drive the first-level screw 5 to rotate synchronously. When the first-level screw 5 is rotating, the first-level slide 7 threaded thereon will perform a left and right linear displacement along the first-level screw 5. The left and right movement of the first-level screw 5 can drive the solder head 16 to perform a left and right linear displacement, completing the free movement of the solder head 16 in the X-axis direction, thereby facilitating the movement and conversion of the soldering point and improving the flexibility of soldering.

[0038] In this embodiment, secondary guide rails 20 are fixedly mounted on both sides of the upper surface of the base plate 1, and the secondary guide rails 20 and the primary guide rails 4 are arranged perpendicular to each other;

[0039] Furthermore, a secondary slide 21 is slidably connected between the two secondary guide rails 20, and a whole-board limit box 22 is fixedly mounted on the upper surface of the secondary slide 21;

[0040] When the whole board limit box 22 is actually used, it can place the adapted cooling fan circuit board, so that the cooling fan circuit board can be limited and fixed by the whole board limit box 22 to prevent it from moving and improve the stability of the soldering process.

[0041] In this embodiment, in order to drive the entire plate limit box 22 to move forward and backward, a secondary cylinder 23 is fixedly installed on the outer wall of the bottom end of the rear vertical plate 2 by bolts. The output end of the secondary cylinder 23 is telescopically connected to a gas rod, and the top end of the gas rod is fixedly connected to the secondary slide 21.

[0042] This structural design, through the set secondary cylinder 23, can drive the circuit board in the entire board limit box 22 to move forward and backward through its pneumatic rod, so that the soldering point can be converted into forward and backward displacement through the forward and backward movement of the circuit board. By coordinating the movement effect of the solder head 16 in the X-axis direction, the soldering dead angle of the plane can be effectively reduced, and the soldering has better flexibility in use.

[0043] Working principle: Before use, the tin wire that needs to be soldered can be placed on the tin inlet head 9, so that the tin wire in the soldering process can be step-by-step discharged through the tin inlet head 9;

[0044] In actual use, the circuit board that needs to be soldered and is adapted to the size of the present invention is placed in the whole board limit box 22. The whole board limit box 22 can be used to limit and fix the circuit board of the cooling fan to prevent it from moving, thereby improving the stability of the soldering process.

[0045] After placement is completed, the pneumatic rod 10 is driven to extend by the first-stage cylinder 9. When the pneumatic rod 10 extends, it will simultaneously drive the lower mounting plate 11 at the tail end to descend as a whole. The overall descending of the lower mounting plate 11 can drive the soldering heads 16 on both sides to descend, so that the descending soldering heads 16 can contact the circuit board of the cooling fan, completing the free movement effect of the soldering heads 16 in the Z-axis direction.

[0046] At the same time, during the descending process, the tin feeding head 19 works to spit out tin. When the soldering head 16 contacts the circuit board of the cooling fan, the spitted tin wire can be heated by the soldering head 16 to solder the entire circuit board of the cooling fan. In this way, the entire board of the cooling fan circuit board can be placed and soldered.

[0047] The utility model adopts the structural design of double soldering heads. In actual use, in a single soldering operation, the soldering work of two areas can be completed, thereby effectively improving the soldering efficiency of the circuit board and increasing the overall soldering speed. Compared with traditional soldering equipment, the utility model can effectively increase the processing efficiency by two times, save half the processing time, and has the characteristics of fast soldering processing.

[0048] The present invention is provided with a secondary motor 13, which can drive the secondary screw 12 to rotate. Since the secondary screw 12 is a forward and reverse threaded rod, when the secondary screw 12 rotates, the two threaded seats 14 thereon will move relative to each other, that is, move away from or approach each other. In this way, the relative movement of the two threaded seats 14 can drive the two sets of soldering heads 16 to move, thereby achieving the purpose of adjusting the distance between the two soldering heads 16.

[0049] In actual use, by adjusting the distance between the two soldering heads 16, it is possible to perform soldering treatment on soldering areas at different distances of the circuit board, which greatly improves the use effect of the utility model, reduces the limitations of use, and has the characteristic of dynamically adjustable soldering point distance, which is more practical.

[0050] Moreover, the utility model is provided with a first-stage motor 6 that can rotate, and the output shaft of the first-stage motor 6 can drive the first-stage screw 5 to rotate synchronously. When the first-stage screw 5 is rotating, the first-stage slide 7 threadedly connected thereto can perform a left-right linear displacement along the first-stage screw 5, thereby driving the soldering head 16 to perform a left-right linear displacement through the left-right movement of the first-stage screw 5, completing the free movement of the soldering head 16 in the X-axis direction, thereby facilitating the movement and conversion of the soldering point, and improving the flexibility of soldering;

[0051] The secondary cylinder 23 can drive the circuit board in the entire board limit box 22 to move forward and backward through its pneumatic rod, so that the soldering point can be converted into a forward and backward displacement through the forward and backward movement of the circuit board. By coordinating the movement effect of the soldering head 16 in the X-axis direction, the soldering dead angle of the plane can be effectively reduced, and the soldering has better flexibility in use.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
