[0024] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solutions of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0025] like Figure 1 As shown, a PCB board batch welding auxiliary device includes a displacement component 1, a substrate 3, a first clamping component 4 and a second clamping component 5. The displacement component 1 includes a base 11, a screw 12, a displacement motor 13 and a slider 14. The base 11 is strip-shaped, the screw 12 is rotatably connected to the base 11, the displacement motor 13 is arranged at one end of the base 11, the displacement motor 13 is connected to the screw 12 to drive the screw 12 to rotate, and the slider 14 is rotatably connected to the screw 12. A guide rail is also provided on the base 11, and a through hole corresponding to the guide rail is provided on the slider 14. When the screw 12 rotates, the slider 14 is driven to move left and right. The substrate 3 and the slider 14 are detachably connected by multiple bolts. When the slider 14 moves left and right, it drives the substrate 3 to move left and right. The first clamping component 4 is arranged on the substrate 3 and fixedly connected to the substrate 3. The second clamping component 5 is arranged on the substrate 3 and slidably connected to the substrate 3.

[0026] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, the first clamping assembly 4 and the second clamping assembly 5 are symmetrically arranged on the base plate 3. The first clamping assembly 4 includes a first clamping seat 41, a first elastic member 42 and four first clamping plates 43. The first clamping seat 41 is provided with a first groove 411 on a side close to the second clamping assembly 5. The first groove 411 is a strip-shaped rectangular groove. The first elastic member 42 adopts a compression spring. A plurality of first elastic members 42 are provided in the first groove 411. One side of each first clamping plate 43 is connected to the first clamping seat 41 via the plurality of first elastic members 42. The first clamping plate 43 moves toward the second clamping plate 53 under the elastic force of the first elastic member 42. The four first clamping plates 43 are connected side by side to the first clamping seat 41. The second clamping assembly 5 includes a second clamping seat 51, a second elastic member 52 and four second clamping plates 53. The second clamping seat 51 is provided with a second groove 511 on one side close to the first clamping assembly 4. The second groove 511 is also a strip-shaped rectangular groove. The second elastic member 52 adopts a compression spring. A plurality of second elastic members 52 are provided in the second groove 511. One side of each second clamping plate 53 is connected to the second clamping seat 51 through the second elastic member 52. The four second clamping plates 53 correspond to the four first clamping plates 43 in position. The second clamping plates 53 move toward the first clamping plates 43 under the elastic force of the second elastic member 52. The four second clamping plates 53 are connected side by side on the second clamping seat 51. The first clamping plate 43 and the corresponding second clamping plates 53 are used to clamp the PCB board, so that the first clamping assembly 4 and the second clamping assembly 5 can clamp four PCB boards (such as Figure 6 As shown), multiple first clamping plates 43 and second clamping plates 53 can be provided in order to clamp multiple PCB boards during use.

[0027] like Figure 1 、 Figure 2 and Figure 3As shown, two first slide grooves 31 and one second slide groove 32 are provided on the substrate 3. The second slide groove 32 is arranged in the middle of the upper end surface of the substrate 3. The two first slide grooves 31 are symmetrically arranged on both sides of the second slide groove 32. The bottom end of the second clamping component 5 is provided with a first slider 56 corresponding to the first slide groove 31. The first slide groove 31 is a T-shaped groove, and the first slider 56 is a corresponding T-shaped block. The second clamping component 5 is slidably connected to the substrate 3 by sliding the first slider 56 in the first slide groove 31, so that the second clamping component 5 can adjust the distance between it and the first clamping component 4, which is convenient for clamping PCB antennas of different lengths or widths. The second slide groove 32 is also a T-shaped groove, and a T-shaped bolt 33 is provided in the second slide groove 32. The T-shaped bolt 33 passes through the second clamping component 5 upward, and a first locking nut 34 is connected to the T-shaped bolt 33. The first locking nut 34 is arranged above the second clamping component 5. The first locking nut 34 is a butterfly nut. When the first locking nut 34 is tightened, the second clamping component 5 is connected and tightened to the base plate 3. By loosening the first locking nut 34, the second clamping component 5 can be moved left and right to adjust its distance from the first clamping component 4.

[0028] like Figure 1 、 Figure 4 and Figure 5 As shown, a first support plate 44 is connected to one side of the first clamping plate 43 close to the second clamping assembly 5, and a second support plate 54 is connected to one side of the second clamping plate 53 close to the first clamping assembly 4. The first support plate 44 and the second support plate 54 are both short plates arranged laterally. The PCB board can be placed on the two support plates when being clamped. A first anti-slip pad 45 is provided on the first clamping plate 43 and the first support plate 44, and a second anti-slip pad 55 is provided on the second clamping plate 53 and the second support plate 54. The anti-slip pad can prevent the PCB board from sliding and protect the PCB board.

[0029] like Figure 1 and Figure 6As shown, the displacement assembly 1 is used to drive the substrate 3 to switch between the first position and the second position. When the substrate 3 is in the first position, it is located at the leftmost end of the base 11. When the substrate 3 is in the second position, it is located at the rightmost end of the base 11. When in use, when multiple PCB boards need to be soldered, the displacement assembly 1 drives the base plate 3 to move to the first position, and slides the second clamping assembly 5 to a certain position away from the first clamping assembly 4. At this time, the distance between the first clamping assembly 4 and the second clamping assembly 5 is slightly smaller than the length of the PCB board, and the position of the second clamping assembly 5 is fixed by the first locking nut 34. The staff places the PCB board between the first clamping plate 43 and the corresponding second clamping plate 53. Under the elastic force of the first elastic member 42 and the second elastic member 52, the first clamping plate 43 and the second clamping plate 53 fix the PCB board. Since it is clamped by the spring force on both sides, the pressure is smaller than that of a vise clamp and will not damage the PCB board. After placing the four PCB boards, the displacement assembly 1 drives the base plate 3 to move to the second position, and the staff at the second position performs soldering on the PCB board at this time. After soldering is completed, the displacement assembly 1 drives the base plate 3 back to the first position, and the staff at the first position lightly pushes the first clamping plate 43 or the second clamping plate 53 to remove the PCB board. The welding process can be done either manually or by an automatic soldering machine. The welding operation position is separated from the position for picking up and placing the PCB board. In this embodiment, multiple devices are set up, and a worker at the first position can correspond to multiple welding workers at the second position. The worker at the first position is responsible for loading and unloading the board, thereby improving the efficiency of the soldering operation.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
