Then, the fastening seat 2 is connected to the positioning seat 1. At this time, the circuit board is clamped between the positioning seat 1 and the fastening seat 2. Finally, the welding equipment welds and fixes the components to be welded and the circuit board through the clamping opening 168. The clamping mechanism 16 can clamp and fix the components to be welded. By cooperating with the movable part 45 and the first clamping part 162, the position of the first clamping part 162 can be controlled by the first driving part 41, which facilitates the clamping and fixing of the components to be welded, and can clamp and fix multiple components to be welded. At the same time, it is convenient to move the positioning component after the components to be welded are clamped and fixed, and move the positioning component to the welding equipment, so as to weld multiple components to be welded at the same time, thereby improving the welding efficiency.

The clamping end of the second clamping member 165 is located on one side of the first clamping space, that is, the clamping end of the first clamping member 162, the clamping end of the second clamping member 165, and the side wall of the clamping opening 168 together form the clamping space. Through the arrangement of the first clamping member 162 and the second clamping member 165, the component to be welded can be clamped and fixed from two vertical directions, making the clamping of the component to be welded more stable. Depending on the shape of the component to be welded, the clamping ends of the first clamping member 162 and the second clamping member 165 can be configured as clamping grooves that conform to the shape of the component to be welded, thereby making the clamping of the component to be welded more stable.

[0038] The positioning assembly also includes a positioning base 1, to which a clamping mechanism 16 is connected. Specifically, the positioning base 1 includes a positioning plate 11 and a mounting plate 12. The positioning plate 11 and the mounting plate 12 are detachably connected by screws, and the mounting plate 12 is connected to the top side of the positioning plate 11. The clamping mechanism 16 is connected to the bottom side of the mounting plate 12, and the mounting plate 12 has a clearance opening for the clamping mechanism 16 to pass through. Depending on the welding position and number of components to be welded, multiple clamping mechanisms 16 can be connected to the mounting plate 12. The detachable connection between the positioning plate 11 and the mounting plate 12 facilitates the use of different mounting plates 12 for welding different circuit boards. The top side of the mounting plate 12 has a material inlet 121 communicating with the first clamping space, which is used to insert the component to be welded. Two positioning pins 13 are connected to the top edge of the positioning plate 11, and the mounting plate 12 is located between the two positioning pins 13.

[0039] Reference Figure 9 and Figure 10 As shown, the positioning assembly also includes a fastening seat 2, which includes a cover plate 22, a pressure plate 21, a pressure block 23, and a fourth elastic element 27. Specifically, the pressure plate 21 is connected to the top side of the cover plate 22, the pressure block 23 is slidably connected to the cover plate 22 and passes through the cover plate 22, the movement path of the pressure block 23 faces the material inlet 121, the fourth elastic element 27 can be regarded as a spring, and the fourth elastic element 27 is located between the pressure block 23 and the pressure plate 21, with both ends of the fourth elastic element 27 connected to the pressure block 23 and the pressure plate 21 respectively. A baffle 231 is provided on the edge of the pressure block 23 near the pressure plate 21, the baffle 231 can abut against the side of the cover plate 22 near the pressure plate 21, the baffle 231 can limit the extreme movement position of the pressure block 23, and prevent the pressure block 23 from detaching from the cover plate 22. The fastening seat 2 is connected to the positioning seat 1, and the fastening seat 2 and the positioning seat 1 form a second clamping space, which is used to accommodate the circuit board. The fastening base 2 includes multiple pressure blocks 23, which correspond to the material inlet 121. These pressure blocks 23 apply pressure to the corresponding positions on the circuit board corresponding to the components to be soldered, ensuring a tight fit between the components and the circuit board. Simultaneously, the pressure blocks 23 prevent the circuit board from wobbling within the second clamping space, guaranteeing soldering quality. The cover plate 22 has first positioning holes 26 corresponding to the positions of the positioning pins 13. The positioning pins 13 are inserted into the first positioning holes 26 to perform positioning during assembly of the fastening base 2 and the positioning base 1.

[0040] The top side of the mounting plate 12 is connected to a positioning block 15, and the bottom side of the cover plate 22 is provided with a relief groove 25 for accommodating the top of the positioning block 15. After the circuit board is placed in the second clamping space, the positioning block 15 passes through the through hole on the circuit board to position the circuit board and prevent the circuit board from shaking in the horizontal direction.

[0041] Reference Figure 11As shown, the top four corners of the positioning plate 11 are also connected to limiting posts 14. Two limiting posts 14 located on the same side of the mounting plate 12 have protrusions 141 on opposite sides of their top ends. The cover plate 22 is connected to a limiting mechanism 24. The limiting mechanism 24 includes a limiting seat 241, a fixing pin 242, and a fifth elastic element 244. The cover plate 22 has a third sliding groove, and the limiting seat 241 is slidably connected to the third sliding groove. The fifth elastic element 244 can be considered as a spring, and its two ends abut against the ends of the limiting seat 241 and the third sliding groove, respectively. The limiting seat 241 has a second limiting hole 245, which has an oblong cross-section. The fixing pin 242 is cylindrical and engages with the cover plate 22, passing through the second limiting hole 245. The movement of the limiting seat 241 allows the fixing pin 242 to abut against the two ends of the second limiting hole 245. The engagement of the fixing pin 242 with the second limiting hole 245 is used to limit the extreme movement position of the limiting seat 241 and prevent the limiting seat 241 from disengaging from the third slide groove. The limiting seat 241 is also provided with a second positioning hole 243 penetrating the limiting seat 241, and the cover plate 22 is provided with a third positioning hole penetrating the cover plate 22. The dimensions of the second positioning hole 243 and the third positioning hole are adapted to the limiting post 14, and the limiting post 14 and the protrusion 141 can pass through the second positioning hole 243 and the third positioning hole. By pressing the limiting seat 241, the limiting seat 241 is moved, so that the center line of the second positioning hole 243 can be collinear with that of the third positioning hole. By moving the fastening seat 2, the limiting post 14 can pass through the third positioning hole and the second positioning hole 243. After stopping pressing the limiting seat 241, the limiting seat 241 is reset. At this time, the side wall of the second positioning hole 243 abuts against the side wall of the limiting post 14. The protrusion 141 of the limiting post 14 can prevent the limiting post 14 from disengaging from the second positioning hole 243 and the third positioning hole.

The movable member 45 can move along the length direction of the first limiting hole. The first driving member 41 is a linear driving member. The output end of the first driving member 41 is connected to a push block 42. The first driving member 41 can drive the push block 42 to move, and the guide plate 44 is located on the moving path of the push block 42. This allows the first driving member 41 to drive the push block 42 to abut against the guide plate 44. The movement of the guide plate 44 drives the movable member 45 to move along the first limiting hole. The top end of the movable member 45 is located in the driving channel. The movable member 45 can move in the direction between the first clamping member 162 and the second clamping member 165. This allows the movable member 45 to abut against the side walls of the first clamping member 162 and the second clamping member 165 during its movement. The movement of the movable member 45 drives the first clamping member 162 and the second clamping member 165 to move, so that the clamping ends of the first clamping member 162 and the second clamping member 165 both move away from the side wall of the clamping opening 168.

[0043] The drive assembly 4 also includes a third elastic element 47, which can be considered as a spring. The third elastic element 47 is located between the end of the guide plate 44 away from the first drive member 41 and the end of the first slide groove. The end of the first slide groove is also provided with two latches 48, and the end of the guide plate 44 is provided with two protrusions 46. The protrusions 46 can move along the side wall of the latches 48, that is, the end of the protrusions 46 can extend into the latches 48. When the push block 42 stops applying pressure to the guide plate 44, the third elastic element 47 can reset the guide plate 44.

The welding clamping device also includes a control component 5, which includes multiple switches 51, and the switches 51 are configured to control the first drive components 41. Specifically, the switches 51 are connected to a control valve, the control valve is connected to an air supply unit 52, and each first drive component 41 is connected to a reversing valve. Thus, the start and stop of different first drive components 41 can be controlled by different switches 51, thereby enabling end-point control of the movement of the first clamping member 162 and the second clamping member 165 in different positioning components.

[0045] The welding clamping device also includes a support assembly 3, which comprises a first support plate 31 and a second support plate 32 arranged in parallel. The first support plate 31 is located above the second support plate 32, and the first support plate 31 and the second support plate 32 are connected by a support column 33. The drive assembly 4 and the switch 51 are both connected to the first support plate 31, and the air supply unit 52 is connected to the second support plate 32. Four first guide blocks 34 and four pads 35 are connected to the first support plate 31. The first guide blocks 34 are provided with guide grooves arranged perpendicular to the first support plate 31. (Refer to...) Figure 15 As shown, the four guide grooves correspond to the four corners of the positioning seat 1, and the pad 35 is located on the guide path of the guide groove.

[0046] Reference Figure 14 As shown, the welding clamping device also includes a top-loading assembly 6, which includes a second driving member 61, a lifting plate 62, and a first top-loading rod 64. The second driving member 61 is a linear driving member, connected to the second support plate 32, and its driving path is perpendicular to the second support plate 32. The lifting plate 62 is connected to the output end of the second driving member 61, and the second driving member 61 can drive the lifting plate 62 to rise and fall. A guide rod is connected to the bottom of the first support plate 31, and a second guide block 63 is provided on the lifting plate 62. The second guide block 63 has a guide hole penetrating through it, and the guide rod is slidably connected to the guide hole. The lifting plate 62 can be guided to rise and fall through the cooperation of the guide rod and the guide hole. A blocking post 36 is connected to the second support plate 32, which is used to limit the lifting plate 62 when it descends. The first top-loading rod 64 is perpendicularly connected to the top side of the lifting plate 62, and the number and position of the first top-loading rod 64 correspond to the clamping mechanism 16. The movable component 45 includes a top-feeding hole arranged axially along the movable component 45. Driven by the second drive component 61, the first top-feeding rod 64 can pass through the first support plate 31 and the top-feeding hole, and the end of the first top-feeding rod 64 can be located within the first clamping space. After the component to be welded is welded to the circuit board, the second drive component 61 can drive the first top-feeding rod 64 upward, thereby causing the first top-feeding rod 64 to abut against the welding component and drive the welding component upward, thus causing the welding component and the circuit board to disengage from the positioning seat 1.

[0047] The lifting assembly also includes second lifting rods 65. Multiple second lifting rods 65 are vertically connected to the top side of the lifting plate 62. Driven by a second driving member 61, the second lifting rods 65 can pass through the first support plate 31 and the positioning seat 1, with their ends positioned within the second clamping space. After the component to be welded is welded to the circuit board, the second driving member 61 can drive the second lifting rods 65 upwards, causing them to abut against the circuit board and lift it, thus detaching the welded component and circuit board from the positioning seat 1. The second lifting rods 65 apply pressure to the circuit board, allowing the first lifting rod 64 and the second lifting rod 65 to simultaneously lift the welded component and circuit board from the positioning seat 1, preventing excessive pressure from the first lifting rod 64 that could damage the welded component.

[0048] In use, firstly, the positioning seat 1 is moved so that it moves along the guide groove of the first guide block 34 and abuts against the pad block 35. At this time, the end of the movable part 45 is located in the drive channel. Then, the first drive member 41 is started by the switch member 51. The first drive member 41 drives the movable part 45 to move. The movable part 45 abuts against the first clamping member 162 and the second clamping member 165 and compresses the first elastic member 164, the second elastic member 167 and the third elastic member 47. Then, the component to be welded is inserted into the clamping space. Then, the first drive member 41 drives the push block 42 to reset. At the same time, the first elastic member 164 drives the first clamping member 162 to reset, the second elastic member 167 drives the second clamping member 165 to reset, and the third elastic member 47 drives the movable part 45 to reset. At this time, the component to be welded is clamped in the clamping space. After all the components to be welded are clamped and fixed, the circuit board is placed in the second clamping space and abuts against the components to be welded. Then, the fastening seat 2 and the positioning seat 1 are engaged by the limiting post 14 and the limiting mechanism 24. At this time, the circuit board is clamped between the positioning seat 1 and the fastening seat 2. Then, the positioning component is moved to the welding position of the welding equipment. The welding equipment welds and fixes the components to be welded and the circuit board through the drive channel and the clamping port 168. Further, after the welding is completed, the positioning component is moved along the guide groove of the first guide block 34 and abuts against the pad block 35. Then, the fastening seat 2 is disengaged from the positioning seat 1. The second drive member 61 drives the first ejector rod 64 and the second ejector rod 65 to rise, so that the first ejector rod 64 and the second ejector rod 65 simultaneously drive the welding components and the circuit board to disengage from the positioning seat 1. At this time, the welding components and the circuit board after welding are removed.
