[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Reference Figures 1 to 5 The present application provides an electronic component welding tool for clamping a large electronic board 1 and a small electronic board 2. The size of the large electronic board 1 is larger than that of the small electronic board 2. It includes a fixed seat 3, two groups of clamping members 4 arranged opposite to each other and used to simultaneously clamp the side of the large electronic board 1, a connecting rod 5 connected to the two clamping members 4 at both ends, and a driving component 6 installed on the fixed seat 3. The driving end of the driving component 6 is connected to the middle end of the connecting rod 5, and the fixed seat 3 is also fixed with a linear driving member 7. The driving end of the linear driving member 7 is connected to a force-applying component 8. The end of the force-applying component 8 is fixed with a clamping component 9. One end of the clamping component 9 is fixedly connected to the force-applying component 8, and the other end is used to press the small electronic board 2 against the large electronic board 1.

[0030] When in use, first clamp the side of the large electronic board 1 with the two clamping parts 4, then hold the small electronic board 2 and bring the small electronic board 2 close to its welding installation area, and through the extension and contraction of the linear drive part 7, drive the force-applying component 8 and the clamping component 9 to move simultaneously until the other end of the clamping component 9 presses the small electronic board 2 against the large electronic board 1, and then the subsequent welding work can be carried out to improve the technical problem that the existing clamp is inconvenient to clamp two electronic components with different board areas, and ensure the smooth progress of the welding work.

[0031] It should be noted that, for two electronic components with different board areas (such as the large electronic board 1 and the small electronic board 2 of the present application), the welding is usually performed by edge butt welding.

[0032] Among them, the driving component 6 and the linear driving component 7 are both located on the same side of the fixed seat 3, and the force-applying component 8 extends in a length direction perpendicular to the linear driving component 7, the clamping component 9 is perpendicular to the force-applying component 8, and the linear driving component 7 and the clamping component 9 are located on the same side of the force-applying component 8.

[0033] The linear drive 7 comprises a cylinder 71 and a storage plate 72 fixedly connected to the piston end of the cylinder 71 at one end. The force-applying assembly 8 is connected to the other end of the storage plate 72. The cylinder 71 enables the storage plate 72 to be extended and retracted. Alternatively, the cylinder 71 can be an electric cylinder, a worm gear mechanism, or the like.

[0034] Reference Figures 2 to 4 The clamping member 4 includes a clamping plate 41 and an intermediate rod 42 with one end fixedly connected to the clamping plate 41. The clamping plate 41 is used to clamp the side of the large electronic board 1, and the other end of the intermediate rod 42 is connected to the end of the connecting rod 5.

[0035] During use, the two clamping plates 41 are clamped on the sides of the large electronic board 1 at the same time to ensure the stability of the large electronic board 1 when being clamped, and to ensure the stability of subsequent welding work.

[0036] The clamping member 4 also includes an X-direction buffer component 43, which includes an X-direction sleeve rod 431 with one end fixedly connected to one end of the intermediate rod 42, an X-direction slide rod 432 with one end slidingly connected to the other end of the X-direction sleeve rod 431, and an X-direction spring 433 sleeved on the X-direction slide rod 432. The other end of the X-direction slide rod 432 is fixedly connected to the clamping plate 41, and the X-direction spring 433 is located in the X-direction sleeve rod 431, and its two ends are respectively pressed against the X-direction sleeve rod 431 and the X-direction slide rod 432.

[0037] When the large electronic board 1 is clamped by the two clamping members 4 , the X-direction spring 433 is compressed to buffer the clamping force and prevent the end of the large electronic board 1 from being damaged by excessive clamping.

[0038] In this embodiment, the clamping plate 41 is L-shaped, with its two ends respectively used to abut two adjacent side surfaces of the large electronic board 1. By simultaneously clamping the two clamping plates 41 at two opposite corners of the large electronic board 1, a clamping effect can be formed on all four sides of the large electronic board 1, increasing the clamping stability.

[0039] A stepped hole is formed at the other end of the X-direction sleeve rod 431 , and one end of the X-direction slide rod 432 is T-shaped to fit and be slidably connected to the stepped hole of the X-direction slide rod 432 .

[0040] Furthermore, a flexible layer 411 is fixed on the inner side of the clamping plate 41 . The flexible layer 411 can be made of rubber to protect the large electronic board 1 .

[0041] Clamping member 4 also includes a pressure plate 44, which is fixedly connected to clamping plate 41. Pressure plate 44 and pressing assembly 9 are located on either side of the thickness direction of large electronic board 1. The two pressure plates 44 support large electronic board 1, ensuring stability when large electronic board 1 and small electronic board 2 are pressed against each other.

[0042] Reference Figures 2 to 4 The connecting rod 5 includes a driven rod 51 and two extension rods 52, one end of which is threadedly connected to the two ends of the driven rod 51. The middle end of the driven rod 51 is fixedly connected to the driving end of the driving assembly 6, and the other ends of the two extension rods 52 are rotatably connected to the corresponding clamping parts 4.

[0043] When the sides of the large electronic board 1 are clamped by the two clamping members 4, the two extension rods 52 can be rotated to adjust the overall length of the connecting rod 5; during the adjustment process, the other end of the extension rod 52 is rotated and connected to the middle rod 42 of the corresponding clamping member 4 to ensure the clamping state of the two clamping members 4.

[0044] The driving assembly 6 includes a driving motor 61 fixedly connected to the fixing base 3 and a driving shaft 62 with one end coaxially fixedly connected to the driving end of the driving motor 61 , and the other end of the driving shaft 62 is connected to the middle end of the connecting rod 5 .

[0045] During the welding process, the driving motor 61 can be used to drive the driving shaft 62 to rotate, thereby driving the connecting rod 5, the two clamping members 4, and the clamped large electronic board 1 and small electronic board 2 to rotate simultaneously, thereby adjusting the welding angle.

[0046] On the basis of the above embodiment, the driving assembly 6 further includes a support frame 63 , one end of which is fixedly connected to the fixing seat 3 , and the other end is rotatably connected to the middle end of the driving shaft 62 to support the driving shaft 62 .

[0047] Reference Figure 3 and Figure 5The force-applying assembly 8 includes a Y-direction sleeve rod 81 having one end rotatably connected to the driving end of the linear drive member 7 and an adjusting rod 82 having one end threadedly connected to the other end of the Y-direction sleeve rod 81. One end of the clamping assembly 9 is fixedly connected to the other end of the adjusting rod 82.

[0048] When in use, the length of the force-applying component 8 can be adjusted by rotating the adjusting rod 82 to adjust the position of the pressing component 9, thereby achieving the pressing work of the small electronic board 2 required at different positions.

[0049] In this embodiment, after the adjusting rod 82 is rotated, the Y-direction sleeve rod 81 can be rotated so that the pressing assembly 9 faces the small electronic board 2 .

[0050] The clamping assembly 9 includes a Z-direction sleeve rod 91 with one end fixedly connected to the other end of the adjustment rod 82 of the force-applying assembly 8, a Z-direction slide rod 92 with one end slidably connected to the other end of the Z-direction sleeve rod 91, and a Z-direction spring 93 sleeved on the Z-direction slide rod 92. The two ends of the Z-direction spring 93 are respectively pressed against the Z-direction sleeve rod 91 and the Z-direction slide rod 92.

[0051] When the small electronic board 2 is pressed against the large electronic board 1 by the pressing assembly 9, the other end of the Z-direction slide rod 92 is pressed against the board surface of the small electronic board 2. During this process, the Z-direction spring 93 is compressed to buffer the pressing force and prevent the board surface of the small electronic board 2 from being damaged by excessive pressing.

[0052] A flexible block 921 is fixed to the other end of the Z-direction sliding rod 92 . The flexible block 921 abuts against the small electronic board 2 to protect the surface of the small electronic board 2 .

[0053] A stepped hole is formed at the other end of the Z-direction sleeve rod 91 , and one end of the Z-direction slide rod 92 is T-shaped to fit and slideably connect to the stepped hole of the Z-direction sleeve rod 91 .

[0054] The cross section of the stepped hole is circular, and one end of the Z-direction sliding rod 92 is slidably and rotatably connected to the Z-direction sleeve rod 91 .

[0055] During welding, the large electronic board 1 and the small electronic board 2 being clamped are rotated simultaneously by the driving assembly 6. Under the action of friction force, the Z-direction sleeve rod 91 and the Z-direction slide rod 92 rotate relative to each other at the same time to achieve smooth adjustment of the welding angle.

[0056] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
