[0026] The present invention is further described in detail below in conjunction with the embodiments.

[0027] The specific embodiment of the soldering station for clamping a circuit board provided by the utility model is as follows:

[0028] See also Figure 1-6 The welding table for clamping the circuit board includes a table 1; a leg 19 is installed on the lower side of the table 1, a guard plate 20 is provided on the upper side of the table 1, the upper part of the guard plate 20 is bent, and a lighting lamp 21 is installed on the lower side of the upper part, and the lighting lamp 21 provides light for the upper side of the table 1 to ensure the brightness during the welding operation.

[0029] A welding gun seat 22 is disposed on the upper side of the table 1 ; a groove is provided on the upper side of the welding gun seat 22 for placing a welding gun to prevent the high-temperature head of the welding gun from directly contacting the table 1 .

[0030] A swivel seat 2 is installed horizontally in the middle of the table 1, and the swivel seat 2 passes through the table 1. Figure 3 A through hole 23 is provided in the middle of the table 1. An annular groove 13 is provided in the middle of the rotating seat 2 to match the through hole 23. The annular groove 13 and the through hole 23 are matched to enable the rotating seat 2 to rotate horizontally.

[0031] A horizontal rotating shaft 3 is rotatably installed on the upper part of the rotating seat 2, and clamping arms 4 for clamping the circuit board are provided at both ends of the rotating shaft 3; a sleeve 15 is connected to one side of the lower end of the clamping arm 4, and the sleeve 15 is sleeved on the outer side of the end of the rotating shaft 3 and slides along the outer side of the end of the rotating shaft 3. A second spring 16 is connected between the end of the sleeve 15 and the outer side of the rotating shaft 3. An annular body is provided on the outer side of the rotating shaft 3, and the annular body is connected to the inner end of the second spring 16. The second spring 16 causes the sleeve 15 and the clamping arm 4 to move toward the rotating seat 2.

[0032] When clamping a circuit board, the clamping arms 4 are driven to move the clamping arms 4 and the sleeve 15 away from the center of the table 1, and the circuit board is placed between the clamping arms 4. Then the clamping arms 4 are released, and the second spring 16 moves the clamping arms 4 toward the center, so that the clamping arms 4 on both sides clamp the circuit board.

[0033] A protrusion 17 is provided on the inner side of the clamp arm 4. The function of the protrusion 17 is to support the lower side of the circuit board when clamping the circuit board to prevent the circuit board from contacting the rotating seat 2. An L-shaped groove 18 is provided, which is located on the inner side of the clamp arm 4 and the upper side of the protrusion 17. The groove 18 limits the edge of the circuit board to reduce the circuit board from slipping.

[0034] A gear 5 is provided in the middle of the rotating shaft 3, a protective shell 14 for protecting the gear 5 is provided at the upper end of the rotating seat 2, and a cavity for accommodating the gear 5 is formed in the protective shell 14; the center of the rotating seat 2 is vertically slidably connected to the lifting rod 6, and the lifting rod 6 can extend into the cavity of the gear 5. A clamping block 7 for engaging with the gear 5 is provided at the upper end of the lifting rod 6, and a lifting plate 8 is connected to the lower end of the lifting rod 6. The outer diameter of the lifting plate 8 is larger than that of the rotating seat 2. A gear ring 10 is provided on the upper side of the edge of the lifting plate 8.

The annular body is located at the lower side of the annular groove 13, and the annular body is used to connect with the upper side of the first spring 9.

[0035] The first spring 9 moves the lifting plate 8 and the lifting rod 6 upward, and at the same time, the gear ring 10 is engaged with the clamping plate 11, and the clamping block 7 is engaged with the gear 5; the clamping plate 11 prevents the rotating seat 2 from rotating horizontally, and the clamping block 7 prevents the rotating shaft 3 from rotating vertically. The external force drives the lifting plate 8 and the lifting rod 6 to move downward to overcome the elastic force of the first spring 9, and at the same time, the gear ring 10 is separated from the clamping plate 11, and the clamping block 7 is separated from the gear 5. The lifting plate 8 and the lifting rod 6 drive the gear ring 10 and the clamping block 7 to rise and fall synchronously, realizing synchronous positioning and release.

[0036] When the lifting plate 8 is driven downward by external force, the clamping arm 4 can be driven by hand to rotate the rotating shaft 3 to realize the vertical rotation of the circuit board and change the inclination direction and angle of the circuit board; at the same time, the rotating seat 2 can also drive the circuit board to rotate horizontally, thereby facilitating the insertion of pins into the circuit board pads and then turning the circuit board over for welding. The angle adjustment range is wide and the welding angle adaptability is strong.

[0037] In order to facilitate the adjustment operation, the lifting plate 8 adopts a foot-driven driving member 12, and the driving member 12 is connected to the lower side of the lifting plate 8. The driving member 12 includes a connecting rod and a foot ring. The connecting rod is connected to the lower side of the lifting plate 8, and the lower side of the connecting rod is connected to the foot ring; the foot ring can be driven downward by the foot, and the angle direction of the circuit board can be adjusted with one hand; release the foot ring, and the first spring 9 moves the lifting plate 8 upward to achieve positioning.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents.
