[0017] The present invention proposes a soldering device for circuit board production. Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. During the use of the present invention, the circuit board to be welded is placed on the groove body between the movable placing table and the fixed placing table. The movable placing table can slide and adjust its position in the movable groove above the top table to adapt to the size of the circuit board, making the device more flexible to use. After the circuit board is placed, the circuit board is clamped by the clamping rod to improve stability. During the adjustment process, the hydraulic rod is raised and lowered to adjust the height of the top table. Since the bottom of the clamping rod is installed together with the adjustment rod through the translation groove, the adjustment rod will translate downward inside the translation groove when it moves downward. Since the center of the clamping rod is fixed to the support rod through the top rotating shaft, the clamping rod will rotate inward, so that the top of the clamping rod is close to the circuit board placed on the movable placing table to press the circuit board to prevent displacement during welding.

[0019] 2. During the use of the present invention, the motor drives the second screw rod to rotate, and the first set of rods is installed on the outside of the second screw rod in meshing engagement. At the same time, the first set of rods is fixed to the rightmost clamping block on the top, so the rightmost clamping block will be driven by the first set of rods to translate in the left and right directions. Since the multiple clamping blocks installed in the top array are fixed by springs, when the rightmost clamping block moves to the left, the multiple clamping blocks on the left will also be pushed to the left by the spring. The wires to be welded can be placed in the position between the clamping blocks to clamp the wires, and then the wires can be adjusted to the corresponding position of the circuit board by adjusting the position of the movable plate, and then welding can be performed, reducing position correspondence errors during the welding process.

[0020] 3. During the use of the present invention, the fourth motor drives the third lead screw to rotate. Since the second set of rods is meshedly installed on the outside of the third lead screw, the third lead screw will drive the second set of rods to translate in the left and right directions inside the device when it rotates. The second set of rods and the fixed plate are fixed to each other. Therefore, the second set of rods will drive the fixed plate to move synchronously inside the device when it translates, so as to adjust the position of the fixed head fixed in front of the fixed plate inside the device to adapt to different welding positions of the circuit board and improve the flexibility of the device. The fixed plate is in a cross structure, and the second set of rods can be fixed at the bottom of the fixed plate, and other parts can be installed on the top of the fixed plate, so that the fixed plate can protect different components.

[0021] 4. During the use of the present invention, the second bevel gear is driven to rotate by the first bevel gear, and the bottom of the second bevel gear is fixed to the fourth lead screw. Therefore, when the second bevel gear rotates, the fourth lead screw will also rotate synchronously. Since the fixed head and the fourth lead screw are meshed with each other, the rotation of the fourth lead screw will drive the fixed head to rise and fall, thereby adjusting the height of the soldering head placed inside the fixed head to facilitate the lifting and lowering of the soldering head. During the lifting process, the fixed head will also slide in the slide groove through the slider on the rear side to maintain the stability of the fixed head, thereby preventing the fixed head from tilting and affecting the welding effect.

[0037] Furthermore, a third motor 28 is installed on the upper rear side of the side base 1, and a pulley 29 is fixedly installed on the output end of the third motor 28. Three groups of fans 31 are provided, and pulleys 29 are installed on the rear of the three groups of fans 31. There are four pulleys 29, and the four pulleys 29 are connected by a transmission belt 30. A top mounting frame 32 is installed on the top of the fan 31, and a fourth motor 33 is installed on the left side of the top mounting frame 32. A third lead screw 34 is installed on the output end of the fourth motor 33, and a second set of rods 35 are meshedly installed on the outside of the third lead screw 34. A fixed plate 36 is fixedly installed in front of the second set of rods 35, and a rotating plate 36 is installed on the top of the fixed plate 36. The movable rod 37 and the rotating rod 37 are driven by the fifth motor 38 on the left side. A first bevel gear 39 is installed above the fixed plate 36, and a second bevel gear 40 is installed in meshing relationship in front of the first bevel gear 39. The front of the fixed plate 36 is fixed to the mounting side plate 41, and a fourth lead screw 42 is installed inside the mounting side plate 41. The fourth lead screw 42 is driven by the second bevel gear 40. Two groups of slide grooves 45 are provided in parallel on the left and right sides of the fourth lead screw 42. A fixed head 43 is installed in meshing relationship in front of the fourth lead screw 42. A slider 44 corresponding to the position of the slide groove 45 is installed on the side of the fixed head 43 close to the mounting side plate 41, and a soldering head 46 is installed at the bottom of the fixed head 43.

[0038] Furthermore, the translation table 5 forms a translation structure with the center base 2 through the cooperation between the first screw 4 and the first motor 3, and the translation table 5 forms a sliding structure with the center base 2 through the bottom slide bar 6. During use, the first motor 3 drives the first screw 4 to rotate inside the device, and when the first screw 4 rotates, it drives the externally engaged translation table 5 to translate in the front and rear directions. During the translation process, the bottom slide bars 6 fixedly installed on both sides of the translation table 5 will slide on the sides of the center base 2 to maintain the stability of the translation table 5 during movement, so as to facilitate the adjustment of the position of the circuit board to be soldered inside the device and improve the flexibility of the device during use.

[0039] Furthermore, the top platform 8 forms a lifting structure with the translation platform 5 through the hydraulic rod 7, the clamping rod 11 forms a translation structure with the top platform 8 through the cooperation between the adjustment rod 15 and the translation slot 14, the clamping rod 11 forms a rotation structure with the top shaft 12 and the support rod 13, and the dynamic placement platform 10 forms a translation structure with the top platform 8 through the moving slot 9. During use, the circuit board to be welded is placed on the groove body between the dynamic placement platform 10 and the fixed placement platform 27, and the dynamic placement platform 10 can slide and adjust its position in the moving slot 9 above the top platform 8 to adapt to the size of the circuit board, so that the device can be used It is more flexible. After the circuit board is placed, the circuit board is clamped by the clamping rod 11 to improve stability. During the adjustment process, the hydraulic rod 7 is raised and lowered to adjust the height of the top platform 8. Since the bottom of the clamping rod 11 is installed together with the translation slot 14 and the adjustment rod 15, the adjustment rod 15 will move downward inside the translation slot 14 when it moves downward. Since the center of the clamping rod 11 is fixed to the support rod 13 through the top rotating shaft 12, the clamping rod 11 will rotate inward, so that the top of the clamping rod 11 is close to the circuit board placed on the dynamic placement table 10 to press the circuit board to prevent displacement during welding.

[0040] Furthermore, the movable plate 18 forms a translation structure with the side base 1 through the cooperation between the first gear 17 and the rack 16, and the first gear 17 forms a rotation structure through the cooperation between the driven gear 19 and the driving gear 20. The second motor 21 drives the driving gear 20 to rotate, and the driven gear 19 and the driving gear 20 are meshed with each other, so the driving gear 20 will drive the driven gear 19 to rotate. The driven gear 19 is coaxial with the first gear 17, so the first gear 17 will be driven by the driven gear 19 to rotate synchronously, and the first gear 17 and the rack 16 are meshed with each other, so when the first gear 17 rotates, it will translate on the side of the rack 16, so that the top movable plate 18 can be driven to translate in the front and rear directions inside the device to cooperate with the position of the dynamic placement table 10 and the clamping block 26, so that the wires to be welded are fixed and corresponded to the position of the circuit board.

[0041] Furthermore, multiple groups of clamps 26 are arranged in parallel, the first set of rods 25 and the rightmost clamp 26 are fixed to each other, the clamp 26 forms a translation structure through the cooperation between the first set of rods 25 and the second screw rod 23, and the clamps 26 form a pressing structure through the spring 47. The motor 24 drives the second screw rod 23 to rotate, and the first set of rods 25 is installed on the outside of the second screw rod 23. At the same time, the first set of rods 25 is fixed to the rightmost clamp 26 at the top, so the rightmost clamp 26 will be driven by the first set of rods 25 to translate in the left and right directions. Since the multiple clamps 26 installed in the top array are fixed by the spring 47, when the rightmost clamp 26 moves to the left, the multiple clamps 26 on the left will also be pushed to the left by the spring 47. The wires to be welded can be placed in the position between the clamps 26 to clamp the wires, and then the wires are adjusted to the corresponding positions of the circuit boards by adjusting the position of the movable plate 18, and then welding can be performed, reducing position correspondence errors during the welding process.

[0042] Furthermore, the fixing plate 36 forms a translation structure with the top mounting frame 32 through the cooperation between the second set of rods 35 and the third lead screw 34. The fixing plate 36 is a cross vertical structure with a baffle on the top. The fixing plate 36 and the second set of rods 35 are fixed to each other. The fourth motor 33 drives the third lead screw 34 to rotate. Since the second set of rods 35 are engaged and installed on the outside of the third lead screw 34, the third lead screw 34 will drive the second set of rods 35 to translate in the left and right directions inside the device when it rotates. The second set of rods 35 and the fixing plate 36 are fixed to each other. Therefore, the second set of rods 35 will drive the fixing plate 36 to move synchronously inside the device when it translates, so as to adjust the position of the fixing head 43 fixed in front of the fixing plate 36 inside the device to adapt to different welding positions of the circuit board and improve the flexibility of the device. The fixing plate 36 is a cross structure, and the second set of rods 35 can be fixed at the bottom of the fixing plate 36, and other parts can be installed on the top of the fixing plate 36, so that the fixing plate 36 can protect different parts.

[0043] Furthermore, the rotating rod 37 passes through the top of the fixed plate 36, and the rotating rod 37 is connected to the fixed plate 36 through a bearing. The first bevel gear 39 is installed on the outside of the rotating rod 37. The sizes of the first bevel gear 39 and the rotating rod 37 are consistent. The rotating rod 37 passes through the inside of the fixed plate 36, and the rotating rod 37 is installed inside the fixed plate 36 through a bearing, so that the fixed plate 36 will not be blocked by the rotating rod 37 when it is driven by the third screw 34 to translate left and right. At the same time, the rotating rod 37 will not conflict with the fixed plate 36 when it is driven to rotate by the fifth motor 38. The size and structure of the first bevel gear 39 are consistent with those of the rotating rod 37. Therefore, the rotation of the rotating rod 37 will drive the first bevel gear 39 to rotate. Since the first bevel gear 39 and the second bevel gear 40 are meshed with each other, the rotation of the first bevel gear 39 will drive the second bevel gear 40 to rotate, which is convenient for adjusting the height of the fixed head 43 inside the device.

[0044] Furthermore, the fourth lead screw 42 forms a rotating structure with the mounting side plate 41 through the cooperation between the second bevel gear 40 and the first bevel gear 39, the fixed head 43 forms a lifting structure with the fourth lead screw 42 and the fan 31, and the fixed head 43 forms a sliding structure with the slider 44 and the slide groove 45. During use, the second bevel gear 40 is driven to rotate by the first bevel gear 39, and the bottom of the second bevel gear 40 is fixed to the fourth lead screw 42. Therefore, when the second bevel gear 40 rotates, the fourth lead screw 42 will also rotate synchronously. Since the fixed head 43 and the fourth lead screw 42 are meshed with each other, the fourth lead screw 42 will drive the fixed head 43 to rise and fall when it rotates, and adjust the height of the soldering head 46 placed inside the fixed head 43 to facilitate the lifting and lowering of the soldering head 46. During the lifting process, the fixed head 43 will also slide in the slide groove 45 through the rear slider 44 to maintain the stability of the fixed head 43, so as to prevent the fixed head 43 from tilting and affecting the welding effect.

[0045] Working principle: First, place the circuit board to be welded on the groove body between the movable placing table 10 and the fixed placing table 27. The movable placing table 10 can slide and adjust its position in the movable groove 9 above the top table 8 to adapt to the size of the circuit board. After placing the circuit board, the circuit board is clamped by the clamping rod 11 to improve stability. During the adjustment process, the hydraulic rod 7 is raised and lowered to adjust the height of the top table 8. Since the bottom of the clamping rod 11 is installed together with the adjustment rod 15 through the translation groove 14, the adjustment rod 15 will translate downward inside the translation groove 14 when it moves downward. Since the center of the clamping rod 11 is fixed to the support rod 13 through the top rotating shaft 12, the clamping rod 11 will rotate inward, so that the top of the clamping rod 11 is close to the circuit board placed on the movable placing table 10 to press the circuit board to prevent displacement during welding.

[0046] Then the first motor 3 drives the first lead screw 4 to rotate inside the device. When the first lead screw 4 rotates, it drives the externally engaged translation stage 5 to translate in the front-rear direction. During the translation process, bottom slide bars 6 are fixedly installed on both sides of the translation stage 5, which will slide on the sides of the central base 2 to maintain the stability of the translation stage 5 during movement, so as to facilitate the adjustment of the position of the circuit board to be welded inside the device and improve the flexibility of the device during use. After that, the welded wire is placed between the clamping blocks 26. The motor 24 drives the second lead screw 23 to rotate. The first set of rods 25 is engaged with the outside of the second lead screw 23. At the same time, the first set of rods 25 is fixed to the clamping block 26 on the far right of the top. Therefore, the clamping block 26 on the far right will be driven by the first set of rods 25 to translate in the left-right direction.

[0047] Since the multiple clamping blocks 26 installed in the top array are fixed by springs 47, when the rightmost clamping block 26 moves to the left, the multiple clamping blocks 26 on the left are also pushed to the left by the spring 47. The wires to be welded are placed between the clamping blocks 26 to clamp the wires. Then, the wires are adjusted to the corresponding positions of the circuit boards by adjusting the position of the movable plate 18, and then welding can be performed, thereby reducing position correspondence errors during welding.

[0048] The fourth motor 33 then drives the third lead screw 34 to rotate. Since the third lead screw 34 is meshed with the second set of rods 35 installed on the outside, the third lead screw 34 will drive the second set of rods 35 to translate in the left and right directions inside the device when it rotates. The second set of rods 35 and the fixing plate 36 are fixed to each other. Therefore, the second set of rods 35 will drive the fixing plate 36 to move synchronously inside the device when it translates, so as to adjust the position of the fixing head 43 fixed in front of the fixing plate 36 inside the device to adapt to different welding positions of the circuit board and improve the flexibility of the device. The fixing plate 36 is a cross structure, and the second set of rods 35 can be fixed at the bottom of the fixing plate 36, and other parts can be installed on the top of the fixing plate 36, so that the fixing plate 36 can protect different parts conveniently. The rotating rod 37 runs through the inside of the fixing plate 36, and the rotating rod 37 is installed inside the fixing plate 36 through a bearing, so that the fixing plate 36 will not be blocked by the rotating rod 37 when it is driven by the third lead screw 34 to translate left and right.

[0049] At the same time, when the rotating rod 37 is driven to rotate by the fifth motor 38, it will not conflict with the fixed plate 36. The size and structure of the first bevel gear 39 and the rotating rod 37 are consistent. Therefore, the rotation of the rotating rod 37 will drive the first bevel gear 39 to rotate. Since the first bevel gear 39 and the second bevel gear 40 are meshed with each other, the rotation of the first bevel gear 39 will drive the second bevel gear 40 to rotate. The bottom of the second bevel gear 40 is fixed to the fourth lead screw 42. Therefore, the rotation of the second bevel gear 40 and the fourth lead screw 42 will also rotate synchronously. Since the fixed head 43 and the fourth lead screw 42 are meshed with each other, the rotation of the fourth lead screw 42 will drive the fixed head 43 to rise and fall, adjust the height of the soldering head 46 placed inside the fixed head 43, and facilitate the lifting and lowering of the soldering head 46. During the lifting process, the fixed head 43 will also slide in the slide groove 45 through the slider 44 on the rear side to maintain the stability of the fixed head 43, so as to prevent the fixed head 43 from tilting and affecting the welding effect.

[0050] Finally, the third motor 28 drives the pulley 29 to rotate, and the pulleys 29 are driven by the transmission belt 30 to keep the movement consistent, and then drive the fan 31 to rotate to blow away the exhaust gas generated during the welding process to ensure the safety of the user.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
