Description

Technical Field

[0002] Soldering involves wetting liquid solder onto a substrate to create a joint. This phenomenon is similar to pouring water onto a solid surface, except that the solder solidifies into a joint as the temperature decreases. A soldering machine is a mechanical device equipped with a large transparent window for observing the entire soldering process, playing a crucial role in product development and process optimization. Temperature control utilizes a high-precision, intuitive intelligent controller, offering programmable, perfect curve control, precise temperature control, simple parameter settings, and ease of operation. It can efficiently solder single- and double-sided PCBs in all package types, including CHIP, SOP, PLCC, QFP, and BGA.

[0003] For example, a Chinese invention patent application with publication number CN115502509A discloses a rotating bracket for a soldering machine, comprising a base plate and a rotating assembly. The upper surface of the base plate is connected to a slide rail that slides back and forth via two sets of brackets. A sliding platform is provided between the two tracks of the slide rail, which slides in conjunction with the rail. A lifting assembly is fixed to the top of the sliding platform, and the front of the lifting assembly is connected to the top of the rotating assembly via a fixed base. Both the slide rail and the lifting assembly are electrically driven. This invention solves the problem that the horizontal pins of small transformers cannot be effectively soldered due to angle issues, which often results in excessive or insufficient solder, affecting circuit safety.

[0022] Step 5. Rotate the auxiliary shaft to make the induction plate swing toward the middle. Push the top beam downwards with the push rod cylinder to make the induction plate move toward the workpiece and contact the workpiece.

[0041] like Figure 1 As shown, the present invention provides a soldering machine, including a clamping roller 5 and a soldering module 6. The clamping roller 5 is located below the soldering module 6. A groove 18 is provided on the clamping roller 5. Two clamping plates 17 are movably installed in the groove 18. Side grooves 34 are provided on the two clamping plates 17. Both ends of the workpiece are located in the side grooves 34. The soldering module 6 includes a soldering head 10. The workpiece is first fixed by the two clamping plates 17, and then the soldering head 10 in the soldering module 6 solders the workpiece.

[0042] Example 1

[0043] like Figure 1-Figure 7As shown, one end of the clamping roller 5 is connected to a driving part, and the driving part works to rotate the clamping roller 5. Specifically, an inner cavity 24 is reserved in the clamping roller 5, and a sliding groove 23 is provided in the groove 18. The sliding groove 23 is connected to the inner cavity 24. The clamping plate 17 moves along the sliding groove 23. A main screw 28 is rotatably installed in the inner cavity 24. A shaft body 22 is installed at one end of the main screw 28. The shaft body 22 passes through the clamping roller 5 and the square block 27 and is connected to the main motor 21. The torsional force of the main motor 21 is applied to the main screw 28 through the shaft body 22 as an intermediate body. A motor hole 41 is also provided on the end mounting plate 14. The motor hole 41 is connected to the square mounting groove 19. The main motor 21 passes through the motor hole 41 and is installed at the end At one end of the mounting plate 214, the main motor 21 transmits the torsional force to the main screw 28 through the shaft 22, so that the main screw 28 rotates in the inner cavity 24. Furthermore, the main screw 28 is threaded with two groups of connecting parts, each group of connecting parts consists of four sliding blocks 30, and the four sliding blocks 30 are arranged in a circle on the main screw 28, and there is a gap between adjacent sliding blocks 30. The top of the sliding block 30 passes through the sliding groove 23 and is connected to the bottom end of the splint 17. When the main screw 28 rotates, the splint 17 moves with the sliding block 30. In order to make the splints 17 in the same groove 18 move relative to or opposite to each other, the threads on the adjacent sliding blocks 30 at the same lateral position on the main screw 28 have opposite rotation directions.

[0044] Furthermore, in order to facilitate the detachability of the clamping roller 5, the clamping roller 5 is movably connected to the end mounting plate 1 7 and the end mounting plate 2 14 respectively. A square block 27 is welded at one end of the clamping roller 5, and a card groove 26 is provided on the four sides of the square block 27. A square mounting groove 19 is provided on the inner side of the end mounting plate 2 14. Four protrusions 20 are installed on the side wall of the square mounting groove 19. The four protrusions 20 correspond to the four card grooves 26 respectively. During installation, the square block 27 is first inserted into the square mounting groove 19. A threaded block 25 is welded at the other end of the clamping roller 5, and a threaded groove 29 is provided on the end mounting plate 1 7. The threaded block 25 is located in the threaded groove 29. After the installation of one end of the clamping roller 5 is completed, the threaded block 25 and the threaded groove 29 at the other end of the clamping roller 5 are threadedly connected.

[0045] In order to facilitate the movement of the end mounting plate 7, a screw groove 4 is opened at the top of the processing surface 2, and an internal screw 3 is installed in the screw groove 4. One end of the internal screw 3 passes through the processing surface 2 and is connected to the side motor 8. The side motor 8 is installed at one end of the processing surface 2. The end mounting plate 1 7 and the end mounting plate 2 14 are threadedly connected on the internal screw 3. The end mounting plate 2 14 and the internal screw 3 are rotatably connected. The contact surface between the end mounting plate 2 14 and the internal screw 3 is a smooth surface, and the contact surface between the end mounting plate 1 7 and the internal screw 3 is a threaded surface.

[0046] During specific operation, the main motor 21 is passed through the motor hole 41. At this time, the protrusion 20 fits tightly along the slot 26 to complete the installation of one end of the clamping roller 5. Then, the clamping roller 5 is kept balanced by external force, and the side motor 8 drives the inner screw 3 to rotate, so that the end mounting plate 7 moves toward the clamping roller 5. At the same time, the main motor 21 drives the clamping roller 5 to rotate, so that the other end of the clamping roller 5 is screwed into the threaded groove 29.

[0047] Example 2

[0048] On the basis of the above embodiment 1, in order to improve the stability of the clamping plate 17 clamping the workpiece, as shown in FIG. Figure 9 As shown, a vertical rubber body 31 is installed in the side groove 34, and a spring 32 is symmetrically installed on the inner side of the vertical rubber body 31. The other end of the spring 32 is connected to the inner wall of the side groove 34. When the clamping plate 17 clamps the workpiece, both ends of the workpiece are in contact with the vertical rubber body 31 to ensure the end face of the workpiece. During clamping, if there is an error in the clamping stroke, the workpiece is prevented from being subjected to a harder extrusion force and cracking or breaking.

[0049] Furthermore, two transverse rubber bodies 35 are installed in the side groove 24, and the top and bottom ends of the workpiece are fixed by the relatively movable transverse rubber bodies 35. Specifically, the transverse rubber body 35 is located on the outside of the vertical rubber body 31, and two electromagnets 33 are slidably installed on the side walls of the side groove 34. The transverse rubber body 35 is installed at the front end of the electromagnet 33, and two groups of main magnets 36 are installed between the two electromagnets 33. Both groups of main magnets 36 are charged. The principle is that when the main magnets 36 are not charged, the electromagnet 33 and the adjacent main magnets are in a state of mutual repulsion. Conversely, when the main magnets 36 are charged, the electromagnet 33 and the adjacent main magnets are in a state of mutual attraction. At this time, since the position of the main magnets 36 is fixed, the electromagnet 33 slides in the side groove 34 and drives the transverse rubber body 35 to move toward the workpiece.

[0050] Example 3

[0051] Based on the above embodiment 2, Figure 8 、 Figure 10 and Figure 11As shown, the soldering module 6 is installed on the beam 16, the beam 16 is connected across the processing surface 2, the processing surface 2 is welded to the top of the base 1, and the base 1 is set as a hollow cavity for accommodating the control components of the soldering machine. The linear movement of the beam 16 on the processing surface 2 is realized by the control components. A top beam 13 is installed on the beam 16, and a push rod cylinder 15 is installed on the top beam 13. The push rod cylinder 15 is installed on the top of the beam 16. Two end vertical plates 12 are welded on the top beam 13. The end vertical plates 12 are rotatably connected with a soldering rod 11. A mounting seat 9 is installed on the soldering rod 11, and the soldering head 11 is installed on the mounting seat 9. The top beam 13 is moved up and down by the push rod cylinder 15, which is the Z-direction movement of the soldering head 11. The angle of the soldering rod 11 is adjusted by the rotation of the soldering rod 11 to ensure that it is adjusted to the optimal soldering angle.

[0052] In order to improve the soldering quality and avoid the adjacent solder joints being broken due to excessive solder joints, the soldering module 6 also includes an induction plate 38, and a tin feeding module 39 is also installed in the auxiliary seat body 42. The tin feeding module 39 is located on the inner side of the induction plate 38. The horizontal plane of the bottom end of the induction plate 38 is lower than the horizontal plane of the bottom end of the soldering head 10. The soldering head 10 and the induction plate 38 swing separately, and the swing amplitude of the induction plate 38 is greater than the swing amplitude of the soldering head 10.

[0053] The swinging principle of the induction plate 38 is the same as that of the soldering head 10 . An auxiliary shaft 37 is rotatably connected between the two end vertical plates 12 , and an auxiliary seat 42 is mounted on the auxiliary shaft 37 . The induction plate 38 is mounted on the auxiliary seat 42 .

[0054] Specifically, when soldering a certain point, first rotate the auxiliary shaft 37 to make the induction plate 38 swing toward the middle, and then, the push rod cylinder 15 pushes down the top beam 13 to make the induction plate 13 move toward the workpiece and contact the workpiece. When the induction plate 13 touches the workpiece, the soldering rod 11 rotates to make the soldering head 10 swing toward the middle. When the soldering head 10 swings to the extreme position, the distance between the bottom end of the soldering head 10 and the bottom end of the induction plate 13 is exactly the thickness of the solder joint. The induction plate 13 is located on one side of the solder joint to accurately control the solder joint and prevent the solder joint from fusion. Furthermore, a sensor 40 is also installed on the induction plate 38 to better grasp the contact time point between the induction plate 38 and the workpiece.

[0055] The working principle of the present invention when in use is as follows: first install the clamping roller 5, the main motor 21 passes through the motor hole 41, the protrusion 20 fits tightly along the card slot 26, and the clamping roller 5 is kept balanced by external force. The side motor 8 drives the inner screw 3 to rotate, so that the end mounting plate 7 moves toward the clamping roller 5, and the main motor 21 drives the clamping roller 5 to rotate, so that the other end of the clamping roller 5 is screwed into the thread groove 29. Finally, the external force applied to the clamping roller 5 is released (preferably a manipulator assists the clamping roller 5 to maintain balance), and the workpiece is fixed by the two clamping plates 17. The main screw 28 rotates, and the adjacent sliding blocks 30 at the same horizontal position on the main screw 28, the clamping plate 17 moves with the sliding blocks 30, the main magnet 36 is energized, and the electromagnet 3 3 and the adjacent main magnets are in a state of mutual attraction, the electromagnet 33 slides in the side groove 34, and drives the horizontal rubber body 35 to move toward the workpiece, completing the workpiece clamping, the soldering head 10 solders the workpiece, rotates the auxiliary shaft 37, and makes the induction plate 38 swing toward the middle, and then, the push rod cylinder 15 pushes down the top beam 13, so that the induction plate 13 moves toward the workpiece and contacts the workpiece. When the induction plate 13 touches the workpiece, the sensor 40 works, causing the soldering rod 11 to rotate, causing the soldering head 10 to swing toward the middle. When the soldering head 10 swings to the extreme position, the distance between the bottom end of the soldering head 10 and the bottom end of the induction plate 13 is exactly the thickness of the solder joint, and the induction plate 13 is located on one side of the solder joint.

The side motor (8) drives the inner screw (3) to rotate, so that the end mounting plate (7) moves toward the clamping roller (5), and the main motor (21) drives the clamping roller (5) to rotate, so that the other end of the clamping roller (5) is screwed into the thread groove (29); S2, releasing the external force applied to the clamping roller (5); S3, the main screw (28) rotates, and the adjacent sliding blocks (30) at the same lateral position on the main screw (28) and the clamping plate (17) move together with the sliding blocks (30); S4, the main magnet (36) is charged, the electromagnet (33) and the adjacent main magnet are in a state of mutual attraction, the electromagnet (33) slides in the side groove (34), and drives the lateral rubber body (35) to move toward the workpiece; S5, rotate the auxiliary shaft (37) so that the induction plate (38) swings toward the middle, and the push rod cylinder (15) pushes down the top beam (13), so that the induction plate (13) moves toward the workpiece and contacts the workpiece. After the induction plate (13) and the workpiece touch, the sensor (40) works, so that the soldering rod (11) rotates, and the soldering head (10) swings toward the middle. When the soldering head (10) swings to the extreme position, the distance between the bottom end of the soldering head (10) and the bottom end of the induction plate (13) is exactly the thickness of the solder joint, and the induction plate (13) is located on one side of the solder joint.
