After the coil is welded, the motor is started to drive the second support plate to move downward. The second support plate drives the second connecting rod and the sliding sleeve to move downward. Since the sliding sleeve is blocked by the sliding rod, when the second support plate moves downward, the pressing plate will gradually open, thereby being able to play a role in automatically fixing and releasing the coil.

[0028] Please refer to Figures 1-9 , the present invention provides a technical solution: a positioning device for welding a circuit board of a wireless charger, including a base plate 1, a first support 2 fixedly connected to the base plate 1, a second support 3 installed on the first support 2, and a first support plate 4 and a second support plate 5 fixedly connected to the second support 3. The first support plate 4 and the second support plate 5 are respectively used for placing the circuit board 6 and the coil 7;

[0029] A positioning mechanism is provided on the first support 2, and the positioning mechanism is used to pull the two connecting wires on the coil 7 to two welding positions on the circuit board 6 respectively;

[0030] The positioning mechanism includes a first slide rail 8 fixedly connected to the first support 2, a sliding frame 9 slidably connected to the first slide rail 8, a first limiting component is provided at the bottom of the sliding frame 9, and the first limiting component is used to limit the distance between the two wires on the coil 7 to be equal to the distance between the two welding points on the circuit board 6; a second limiting component is provided on the sliding frame 9, and the second limiting component is used to limit the two wires limited by the first limiting component to the positions at the same height as the welding positions on the circuit board 6; a driving component is provided on the sliding frame 9, and the driving component is used to drive the first limiting component and the second limiting component to operate and drive the sliding frame 9 to slide to straighten the two wires;

[0031] During operation, place the circuit board 6 on the first pallet 4, and then place the coil 7 to be welded on the second pallet 5. Adjust the angle of the coil 7 so that the two connecting wires on the coil 7 are directly opposite to the circuit board 6. At this time, start the driving assembly, and the driving assembly will drive the first limiting assembly and the second limiting assembly to operate. Through the first limiting assembly, the two wires distributed disorderly on the coil 7 can be preliminarily limited, so that the distance between the limited parts of the two wires is equal to the distance between the two welding points on the circuit board 6. Since the wires are limited by the first limiting assembly at this time, the limited part of the wire may be in a longitudinally bent state. At this time, the second limiting assembly restricts the wire in the longitudinally bent state of the limited part to a specific height, which is equal to the height of the welding point on the circuit board 6. After the first limiting assembly and the second limiting assembly complete the limiting, the limited parts of the two wires are exactly located directly in front of the two welding points on the circuit board 6 respectively. At this time, the first driving assembly drives the sliding frame 9 to move backward, and the driving frame drives the first driving assembly and the second driving assembly to move backward, and the limited parts on the wires move backward. Since the welded part on the coil 7 wire usually protrudes a little, and the width of the welded part is usually greater than the diameter of the wire, when the limited part on the wire moves to the welded part position at the end of the wire, at this time, the first limiting assembly and the second limiting assembly pull the welded part of the wire to move closer to the welding points on the circuit board 6. When the driving assembly drives the sliding frame 9 to move to the rearmost position, the welding points of the two wires just fit with the two welding points on the circuit board 6 respectively.

[0032] Refer to Figure 4 、 Figure 6 As a further solution of the present invention, the first limiting assembly includes a connecting frame 10 slidably connected to the sliding frame 9. Symmetrically fixed to the left and right positions at the bottom of the connecting frame 10 are limiting frames 11, and the limiting frames 11 are slidably connected to the sliding frame 9;

[0033] The bottom side part of the limiting frame 11 is symmetrically arranged and is a rod shape inclined outward, and the distance between the upper sides of the two rod-shaped parts is equal to the diameter of the wire;

[0034] During operation, when driving the connecting frame 10 to move downward, the connecting frame 10 drives the two limiting frames 11 connected thereto to move downward. Since the bottom side part of the limiting frame 11 is an inclined rod shape that expands outward, the width range covered by the limiting frame 11 is relatively large. When the limiting frame 11 moves downward, it can cover the wire in the bent state at its bottom through the two inclined rod-shaped parts. As the limiting frame 11 continues to move downward, the limiting frame 11 will continuously push the wire towards the middle part of the limiting frame 11, and finally push the wire to the very center part of the limiting frame 11.

[0035] Refer to Figures 4-6, as a further solution of the present invention, the second limiting component includes a second slide rail 12 fixedly connected to the sliding frame 9. A first rack 13 is slidably connected to the second slide rail 12. Limiting plates 14 are symmetrically slidably connected to the left and right positions at the bottom of the first rack 13. A first spring 15 is connected between the limiting plates 14 and the first rack 13;

[0036] The width of the limiting plate 14 is equal to the diameter of the wire. The limiting plate 14 is located directly below the rod-shaped part of the inner side of the limiting frame 11;

[0037] During operation, while the limiting frame 11 moves downward, the limiting plate 14 is driven to move upward. The limiting plate 14 will first fit against the inclined rod-shaped part inside the limiting frame 11, and then gradually move towards the middle part of the limiting frame 11 under the push of the inclined rod-shaped part of the limiting frame 11; when the limiting plate 14 moves to near the middle part of the limiting frame 11, at this time, the upper surface of the limiting plate 14 will contact the wire located inside the limiting frame 11 and push the wire upward. Finally, the limiting plate 14 will push the wire to the uppermost position inside the limiting frame 11. At this time, the limiting plate 14 cooperates with the limiting frame 11 to complete the limiting of the wire.

[0038] Refer to Figure 4 、 Figure 6 , as a further solution of the present invention, the driving component includes a cylinder 16 fixed on the connecting frame 10. A slider 17 is fixedly connected to the upper end of the cylinder 16. The left and right parts of the slider 17 are slidably connected to the inner wall of the sliding frame 9; two first connecting rods 18 are symmetrically rotatably connected to the left and right positions on the slider 17. The upper end of the first connecting rod 18 is rotatably connected to the first slide rail 8; a second spring 19 is fixedly connected to the slider 17. The upper end of the second spring 19 is fixedly connected to the sliding frame 9; a lifting component is provided at the bottom of the sliding frame 9. The lifting component is used to drive the two limiting plates 14 to move upward synchronously when the connecting frame 10 moves downward;

[0039] The lifting component includes a gear 20 rotatably connected to the bottom side part of the sliding frame 9. A second rack 21 is engaged with the gear 20 and the first rack 13 is engaged with the gear 20. The first rack 13 and the second rack 21 are circumferentially arranged relative to the gear 20; the second rack 21 is fixedly connected to the two limiting frames 11;

[0040] During operation, by starting the cylinder 16, the connecting frame 10 can be driven to move downward first. The connecting frame 10 drives the two limiting frames 11 to move downward. The two limiting frames 11 drive the second rack 21 to move downward. The second rack 21 drives the first rack 13 to move upward through the gear 20. The first rack 13 drives the two limiting plates 14 connected thereto to move upward. Thus, the limiting frame 11 and the limiting plate 14 can be moved downward and upward synchronously, and further, the limiting of the wire can be completed;

[0041] When the cylinder 16 pushes the connecting frame 10 to the bottommost position, at this time, the cylinder 16 continues to operate, and the upper part of the cylinder 16 starts to push the slider 17 to move upward. When the slider 17 moves upward, the two connecting rods 18 connected to it will drive the sliding frame 9 to slide backward along the first slide rail 8. When the sliding frame 9 moves backward, it drives the limit plate 14 and the limit frame 11 to move backward. During the backward movement of the limit frame 11 and the limit plate 14, they will be on the wire.

[0042] Refer to Figures 7-8 , as a further solution of the present invention, a lead screw 22 is rotatably connected inside the first bracket 2, and the lead screw 22 has self-locking property; the second bracket 3 is slidably connected to the first bracket 2 and the second bracket 3 is threadedly connected to the lead screw 22; a motor 23 is fixedly connected to the first bracket 2, and the output shaft of the motor 23 is fixedly connected to the lead screw 22;

[0043] Four limit blocks 24 are fixedly connected to the first support plate 4, and the four limit blocks 24 are respectively engaged with the four corners of the circuit board 6; the left and right positions of the second support plate 5 are symmetrically rotatably connected with pressing plates 25, and a torsion spring 26 is fixedly connected to the pressing plates 25 at the part connected to the second support plate 5, and the torsion spring 26 is fixedly connected to the second support plate 5; a fixing rod 27 inclined downward at an angle of 45 degrees is fixedly connected to the rotating part of the pressing plate 25, the end of the fixing rod 27 is rotatably connected with a second connecting rod 28, the bottom end of the second connecting rod 28 is rotatably connected with a sliding sleeve 29, a sliding rod 30 is slidably connected inside the sliding sleeve 29, and the sliding rod 30 is fixedly connected to the bottom plate 1;

[0044] During operation, starting the motor 23 can drive the lead screw 22 to rotate. When the lead screw 22 rotates, it can drive the second bracket 3 to move upward or downward relative to the first bracket 2; since the coil 7 is circular, it is easy to rotate when placed on the second support plate 5, which may cause the wires on the coil 7 to shift, making it inconvenient for subsequent positioning welding; after the coil 7 is placed on the second support plate 5, starting the motor 23 drives the lead screw 22 to rotate, and the lead screw 22 will drive the second bracket 3 to move upward. The second bracket 3 drives the first support plate 4 and the second support plate 5 to move upward. When the second support plate 5 moves to the uppermost position, the sliding sleeve 29 will disengage from the sliding rod 30, and the pressing plate 25 will press the coil 7 under the action of the torsion spring 26; after the coil 7 is welded, starting the motor 23 drives the second support plate 5 to move downward. The second support plate 5 drives the second connecting rod 28 and the sliding sleeve 29 to move downward. Since the sliding sleeve 29 is blocked by the sliding rod 30, when the second support plate 5 moves downward, the pressing plate 25 will gradually open.
