Description

Technical Field

[0001] The invention relates to the technical field of smoke removal in laser soldering, in particular to a laser soldering device with a smoke removal mechanism. Background Art

[0002] Laser soldering machines on the market tend to produce smoke during the soldering process because the tin wire is melting. When the smoke is thick, it affects the laser beam, resulting in uneven surface temperature of the product and poor welding. In order to reduce the impact of smoke, the conventional practice is to install a smoke extraction pipe next to the smoke to extract the smoke. Regardless of the size of the smoke during the soldering process, the same wind force is used for extraction. Figure 3 Schematic diagram of the existing laser soldering machine exhaust structure on the left.

[0003] However, in reality, because the exhaust speed is too fast or too slow, the effect is poor and poor welding conditions still occur. It is impossible to adaptively adjust the exhaust wind speed according to the density of the real-time smoke, which leads to unsatisfactory exhaust effect and a strong impact on the laser beam, resulting in a low soldering yield.

Since the duct fan is connected to the exhaust pipe, the exhaust pipe corresponds to the solder gap, and the smoke generated during the soldering process is drawn out. Since the smoke detector is a smoke detection camera, the density of the smoke can be detected and monitored in real time. Since the smoke detector is electrically connected to the duct fan, the real-time electrical signal of the density of the smoke fed back by the smoke detector is received through the external control system, and the size of the exhaust wind speed of the duct fan is controlled in real time, so that when the smoke is thick, the exhaust wind speed is accelerated, and when the smoke is weak, the exhaust wind speed is reduced, so that the exhaust wind speed can be adaptively adjusted according to the density of the real-time smoke. Furthermore, two groups of the smoke exhauster 1 are provided, one group of the smoke exhauster 1 is fixedly installed with the laser emission head through a rectangular plate, the smoke exhauster 2 is fixedly installed at the solder notch, and the other group of the smoke exhauster 1 is connected with the smoke exhauster 2; The second smoke exhaust device includes a smoke exhaust channel, an electric butterfly valve, and a three-dimensional smoke exhaust component.

[0012] The smoke detector detects the distribution of smoke. The distribution of smoke can be intuitively seen from the images it captures. The external control system controls the start of motor 1 at each location according to the uniform distribution of smoke. Motor 1 drives the shaft and valve to rotate, so as to control the opening size of the valve. The opening size of the valve at each location can be controlled according to the distribution of smoke. The valve opening at each location is large in the area with more smoke, and small in the area with less smoke.

[0015] Motor 2 drives the gear to rotate, and the gear meshing drives the gear ring to rotate, so that the gear ring drives the connecting plate to rotate synchronously, and then drives the smoke guide tube to rotate in a circle around the gear ring. The smoke detector detects the smoke exhaust situation.

Since the smoke detector is electrically connected to the duct fan, the real-time electrical signal of the smoke density fed back by the smoke detector is received through the external control system, and then the smoke exhaust wind speed of the duct fan is controlled in real time, so that when the smoke is dense, the smoke exhaust wind speed is accelerated, and when the smoke is weak, the smoke exhaust wind speed is reduced, so that the smoke exhaust wind speed can be adaptively adjusted according to the real-time smoke density, reducing the influence of smoke on the laser beam and improving the soldering yield.

[0017] 2. The laser soldering device with a smoke removal mechanism can achieve three-dimensional smoke exhaust through the cooperation of the smoke exhauster 2 and the two sets of smoke exhausters 1.

[0034] Motor 2 812 drives gear 813 to rotate, and gear 813 meshes and drives gear ring 822 to rotate, so that gear ring 822 drives connecting plate 831 to rotate synchronously, and then drives smoke guide tube 838 to rotate in a circle around gear ring 822. Smoke detector 3 detects the smoke exhaust situation. When the smoke exhaust effect in some areas is not good, smoke guide tube 838 is driven to move to the corresponding position, and motor 3 833 is started to drive connecting shaft 834 and fixing ring 837 to rotate, so that smoke guide tube 838 is adjusted to a suitable angle, and motor 4 835 is started. Motor 4 835 drives fan blade 836 to rotate, and then guides the smoke in this area, and draws the smoke to the position of smoke exhaust groove on arc-shaped inner shell 731, so as to further improve the smoke exhaust effect.

[0035] The specific usage and function of this embodiment are as follows: When in use, the smoke exhaust components are equipped on the laser soldering device, and the tin wire is fed to the tin feeding tube 41 through the tin wire feeder 14. Since the feeding device 5 is provided with product coils to be soldered evenly, the linear motor 102 is started, and the linear motor 102 drives the linear motor 102 to move upward or downward, and the linear motor 102 drives the horizontal moving component 91 fixedly connected thereto to move synchronously. The horizontal moving component 91 is composed of a DC motor and a threaded rod, a guide rod, a base, and a slider. The slider is threadedly connected to the threaded rod. By starting the DC motor, the DC motor drives the threaded rod to rotate, and then drives the slider to move horizontally on the guide rod. The slider drives the moving plate 92 fixedly connected thereto to move synchronously, and the moving plate 92 drives the laser transmitter 2 to move, so that the laser transmitter 2 moves on the plane to a position corresponding to the product coil to be soldered; Start the lifting cylinders 42 at various locations, one lifting cylinder 42 drives the fixing plate 43 to move up and down, and then the other lifting cylinder 42 drives the tin delivery tube 41 to move horizontally, so that the tin wire in the tin delivery tube 41 is aligned with the part of the product coil to be soldered; Start the laser transmitter 2, the laser transmitter 2 emits a laser beam to melt the tin wire, and solders the product coil to be soldered. During the soldering process, start the smoke detector 3 and the duct fan 62, the duct fan 62 generates an upward wind force, and since the duct fan 62 is connected to the exhaust pipe 61, the exhaust pipe 61 corresponds to the solder gap, and then the smoke generated during the soldering process is drawn out. Since the smoke detector 3 is a smoke detection camera, the density of the smoke can be detected and monitored in real time. Since the smoke detector 3 is electrically connected to the duct fan 62, the real-time electrical signal of the density of the smoke fed back by the smoke detector 3 is received through the external control system, and then the size of the exhaust wind speed of the duct fan 62 is controlled in real time, so that when the smoke is dense, the exhaust wind speed is accelerated, and when the smoke is weak, the exhaust wind speed is reduced, so that the exhaust wind speed can be adaptively adjusted according to the density of the real-time smoke; To enhance the smoke exhaust effect, the smoke exhauster 2 7 is equipped. When the smoke is exhausted, two sets of duct fans 62 are started at the same time. When the duct fans 62 corresponding to the smoke exhauster 2 7 are started, wind force is generated in the annular box 712 toward the square box 711. Since the inner side of the annular box 712 is connected to the evenly distributed connecting pipes 713, the connecting pipes 713 at various locations simultaneously exhaust air from the inner side of the arc-shaped outer shell 733. Since the arc-shaped inner shell 731 is arranged at the solder notch, and the arc-shaped inner shell 731 is provided with evenly distributed smoke exhaust grooves, and the position thereof is located at the lower side of the solder, when exhausting air, the generated smoke flows downward by wind force, passes through the smoke exhaust grooves on the arc-shaped inner shell 731 to the inner side of the arc-shaped outer shell 733, passes through the arc-shaped partition 732, enters the connecting pipe 713, and is then exhausted outward. The arc-shaped partition 732 prevents smoke from flowing back. The smoke detector 3 detects the distribution of smoke. The distribution of smoke can be intuitively seen from the image it captures. The external control system controls the start of motor 1 723 at various locations according to the uniform distribution of smoke. Motor 1 723 drives the rotating shaft 722 and valve 724 to rotate, so as to control the opening size of valve 724. The opening size of valve 724 at various locations can be controlled according to the distribution of smoke, so that the valve 724 corresponding to the area with more smoke distribution has a larger opening, and the valve 724 corresponding to the area with less smoke distribution has a smaller opening, thereby realizing that the smoke exhaust wind force at various locations can be adjusted in a targeted manner according to the wind force of the smoke amount, thereby improving the smoke exhaust effect. When it is necessary to enhance the smoke exhaust effect, the smoke exhaust enhancement mechanism 8 is equipped. When exhausting smoke, the external system starts motor 2 812, and motor 2 812 drives gear 813 to rotate. Gear 813 engages and drives gear ring 822 to rotate, so that gear ring 822 drives connecting plate 831 to rotate synchronously, and then drives smoke guide tube 838 to rotate in a circle around gear ring 822. Smoke detector 3 detects the smoke exhaust situation. When the smoke exhaust effect in some areas is not good, smoke guide tube 838 is driven to move to the corresponding position, and motor 3 833 is started to drive connecting shaft 834 and fixing ring 837 to rotate, so that smoke guide tube 838 is adjusted to a suitable angle, and motor 4 835 is started. Motor 4 835 drives fan blade 836 to rotate, and then guides the smoke in this area, and draws the smoke to the position of smoke exhaust groove on arc inner shell 731, so as to further enhance the smoke exhaust effect.
