Therefore, it needs to be cleaned before welding, and after cleaning the shaving blades, it needs to wait for drying before welding, and this process takes a long time and affects the welding efficiency. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fully automatic shaving blade welding machine to solve the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A fully automatic shaving blade welding machine includes a welding base, a welding platform is fixedly connected to the top of the welding base, a sliding seat is fixedly connected to the top of the welding platform, a welding head is movably connected to the outer wall of the sliding seat, a suction mechanism is movably connected to the top of the welding platform, and a cooling mechanism is fixedly connected to the outer wall of the suction mechanism;

[0007] The suction mechanism includes:

[0008] A positioning turntable, the positioning turntable is movably connected to the top of the welding platform;

[0009] A driving motor, which is fixedly connected to the bottom of the welding platform, and the output shaft of the driving motor is fixedly connected to the positioning rotating plate;

[0010] A positioning groove, which is opened at the corresponding position of the welding head on the top of the positioning rotating plate. The edge of the positioning groove is a bevel. Under the action of suction, the shaving blade will enter the center position of the positioning groove, playing a role in assisting positioning.

[0011] Preferably, a support net is fixedly connected to the bottom of the welding platform at the corresponding position of the positioning rotating plate, an exhaust box is fixedly connected to the bottom of the support net at the bottom of the welding platform, and an exhaust fan is fixedly connected to the inside of the exhaust box.

[0012] Preferably, ventilation holes are opened at the corresponding positions of the positioning grooves on the top of the positioning rotating plate, and a gas guide plate is fixedly connected to the top of the welding platform at the corresponding position of the support net.

[0013] Preferably, the cooling mechanism includes a guide air pipe, which is fixedly connected to the outer wall of the exhaust box. The exhaust fan will discharge the air in the exhaust box to the guide air pipe, and the air will be discharged from the other end where the guide air pipe is connected to the exhaust box, generating a downward blowing air flow. A fixed bracket is fixedly connected to the outer wall of the guide air pipe, and the fixed bracket is fixedly connected to the top of the welding platform at the corresponding position of the positioning groove.

[0014] Preferably, a linkage rod is movably connected to the inside of the guide air pipe, and the linkage rod is fixedly connected to the outer wall of the welding head. A closing circular plate is fixedly connected to the bottom of the linkage rod. A closing ring plate is fixedly connected to the inner wall of the guide air pipe at the bottom of the closing circular plate, and the closing ring plate and the closing circular plate can cooperate to seal the corresponding cross-section of the guide air pipe. The welding head moves downward along the sliding seat to weld the shaving blade, and at the same time, it will drive the linkage rod downward, and at the same time, drive the closing circular plate downward through the linkage rod. When welding is about to be carried out, the closing circular plate will contact the closing ring plate to seal the cross-section of the guide air pipe.

[0015] Preferably, a branch pipe is fixedly connected to the outer wall of the guide air pipe at the top of the closing ring plate. The end of the branch pipe away from the guide air pipe faces the welding position of the welding head. When the cross-section of the guide air pipe is sealed by the cooperation of the closing ring plate and the closing circular plate, the gas in the guide air pipe will be discharged from the branch pipe and blown to the shaving blade being welded.

[0016] Preferably, a sliding-out plate is fixedly connected to the bottom of the welding platform at the bottom of the guide air pipe. The welded shaving blade is transported to the bottom of the guide air pipe by the positioning rotating plate. When the closing circular plate and the closing ring plate do not seal the cross-section of the guide air pipe, the air flow discharged from the guide air pipe will blow the shaving blade on the positioning rotating plate into the inside of the sliding-out plate. A receiving box is fixedly connected to the outer wall of the welding base at the bottom of the sliding-out plate.

[0017] Preferably, a heat sink is fixedly connected to the top of the welding platform at the bottom of the welding head, and a suction notch is formed in the outer wall of the sliding plate close to the heat sink.

[0018] The present invention provides a fully automatic welding machine for shaving blades. It has the following beneficial effects:

[0019] 1. In this fully automatic welding machine for shaving blades, the exhaust fan continuously works to continuously extract the air inside the exhaust box, thereby generating an inward suction force at the top of the positioning groove. Since the edge of the positioning groove is beveled, under the action of the suction force, the shaving blade will enter the center position of the positioning groove, playing an auxiliary positioning role for rapid and accurate positioning, which is beneficial to improving the welding processing speed.

[0020] 2. When the positioning turntable transports the shaving blade and the solder to the bottom of the air guide plate in this fully automatic welding machine for shaving blades, the air flow enters through the holes in the middle of the air guide plate and then flows to the ventilation holes, entering the exhaust box. The flowing air passes through the top of the shaving blade and the top of the solder to quickly dry the top of the shaving blade, avoiding the influence of the residual liquid on the shaving blade on laser welding, and thus improving the welding processing efficiency.

[0021] 3. After the welding of the shaving blade is completed in this fully automatic welding machine for shaving blades, it is transported by the positioning turntable to the bottom of the air guide pipe. The air flow discharged from the air guide pipe blows the shaving blade on the positioning turntable into the sliding plate, and the shaving blade slides into the receiving box through the sliding plate to unload the completed shaving blade, which can indirectly improve the welding processing speed and thus improve the welding processing efficiency.

[0022] 4. When the welding head moves downward to weld the shaving blade in this fully automatic welding machine for shaving blades, when the cross-section of the air guide pipe is sealed by the cooperation of the closed ring plate and the closed circular plate, the gas in the air guide pipe is discharged from the branch pipe and blows towards the welding shaving blade to weld the shaving blade, and at the same time, the heat sink dissipates heat from the shaving blade during welding, avoiding the heat diffusion of the shaving blade due to welding, resulting in the thermal deformation of the shaving blade and affecting the final quality, and can improve the product qualification rate and indirectly improve the welding processing efficiency.

[0023] 5. In this fully automatic welding machine for shaving blades, during the rotation of the positioning turntable, new shaving blades are continuously placed. Therefore, the air flow inhaled at the top of the support net will contain the residual liquid on the surface of the shaving blade. Then, these liquids are mixed in the gas and discharged from the branch pipe through the air guide pipe and blown towards the welding shaving blade to better cool and lower the temperature of the non-welded part of the shaving blade, which can further ensure the quality of the welding point and improve the welding processing efficiency.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0038] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0039] Embodiment 1: Please refer to Figure 1-8 , the present invention provides a technical solution: a fully automatic shaving blade welding machine, including a welding base 1, a welding platform 2 fixedly connected to the top of the welding base 1, a sliding seat 3 fixedly connected to the top of the welding platform 2, a welding head 4 movably connected to the outer wall of the sliding seat 3, a suction mechanism 5 movably connected to the top of the welding platform 2, and a cooling mechanism 6 fixedly connected to the outer wall of the suction mechanism 5;

[0040] The suction mechanism 5 includes:

[0041] A positioning turntable 501, the positioning turntable 501 is movably connected to the top of the welding platform 2;

[0042] A driving motor 502, the driving motor 502 is fixedly connected to the bottom of the welding platform 2, and the output shaft of the driving motor 502 is fixedly connected to the positioning turntable 501;

[0043] A positioning groove 507, a positioning groove 507 is opened at the corresponding position of the top of the positioning turntable 501 where the welding head 4 is located.

[0044] The stamped shaving blades and the corresponding welding materials are cleaned, and then the corresponding shaving blades and solders are placed into the positioning groove 507 far from the welding head 4. Then, the driving motor 502 drives the positioning turntable 501 to rotate clockwise, transporting the shaving blades and solders to the bottom of the welding head 4. The welding head 4 moves downward along the sliding seat 3 to weld the solder to the shaving blades.

[0045] A support net 505 is fixedly connected to the bottom of the welding platform 2 at the corresponding position of the positioning turntable 501, and an exhaust box 503 is fixedly connected to the bottom of the support net 505 at the bottom of the welding platform 2. An exhaust fan 504 is fixedly connected to the inside of the exhaust box 503.

[0046] When the shaving blades and the solder are pushed to move towards the bottom of the welding head 4, the exhaust fan 504 continuously operates to continuously extract the air inside the exhaust box 503, thereby generating an upward suction force at the top of the positioning groove 507. Since the edge of the positioning groove 507 is a bevel, the shaving blades will enter the center position of the positioning groove 507 under the action of the suction force, playing an auxiliary positioning role.

[0047] A vent hole 508 is provided at the corresponding position of the top of the positioning turntable 501 where it is located in the positioning groove 507, and a gas guide plate 506 is fixedly connected at the corresponding position of the top of the welding platform 2 where it is located in the support net 505.

[0048] When the shaving blade and the solder are transported by the positioning turntable 501 to the bottom of the gas guide plate 506 through the positioning groove 507, the air flow will enter through the hole in the middle of the gas guide plate 506 and then flow to the vent hole 508, and enter the inside of the exhaust box 503. The flowing air flow will pass through the top of the shaving blade and the top of the solder to dry the top of the shaving blade and prevent the liquid remaining on the shaving blade from affecting the laser welding.

[0049] Embodiment 2: Please refer to Figure 1-12 , on the basis of Embodiment 1, the present invention provides a technical solution:

[0050] The cooling mechanism 6 includes a gas guide pipe 601, the gas guide pipe 601 is fixedly connected to the outer wall of the exhaust box 503, a fixed bracket 602 is fixedly connected to the outer wall of the gas guide pipe 601, and the fixed bracket 602 is fixedly connected to the top of the welding platform 2 at the corresponding position of the positioning groove 507.

[0051] The exhaust fan 504 will discharge the air in the exhaust box 503 to the gas guide pipe 601, and the air will be discharged from the other end of the gas guide pipe 601 connected to the exhaust box 503, generating a downward blowing air flow.

[0052] A linkage rod 605 is movably connected inside the gas guide pipe 601, and the linkage rod 605 is fixedly connected to the outer wall of the welding head 4. A closing circular plate 606 is fixedly connected to the bottom of the linkage rod 605. A closing ring plate 607 is fixedly connected to the inner wall of the gas guide pipe 601 at the bottom of the closing circular plate 606, and the closing ring plate 607 and the closing circular plate 606 can cooperate to seal the corresponding cross-section of the gas guide pipe 601.

[0053] When the positioning turntable 501 moves the shaving blade and the solder to the bottom of the welding head 4 through the positioning groove 507, the welding head 4 moves downward along the sliding seat 3 to weld the shaving blade. At the same time, it will drive the linkage rod 605 to move downward, and at the same time drive the closing circular plate 606 to move downward through the linkage rod 605. When welding is about to be performed, the closing circular plate 606 will contact the closing ring plate 607 to seal the cross-section of the gas guide pipe 601.

[0054] A branch pipe 608 is fixedly connected to the outer wall of the gas guide pipe 601 at the top of the closing ring plate 607, and the end of the branch pipe 608 away from the gas guide pipe 601 faces the welding position of the welding head 4.

[0055] When the cross-section of the air duct 601 is sealed by the cooperation of the closing ring plate 607 and the closing circular plate 606, the gas in the air duct 601 will be discharged from the branch pipe 608 and blown towards the welding shaving blade. When welding the shaving blade, new shaving blades will be continuously placed during the rotation of the positioning turntable 501. As a result, the airflow inhaled at the top of the support mesh 505 will contain the residual liquid on the surface of the shaving blade. Then, these liquids will be mixed in the gas and discharged through the air duct 601 from the branch pipe 608 and blown towards the welding shaving blade, better cooling and lowering the temperature of the non-welded part of the shaving blade.

[0056] At the bottom of the welding platform 2, a sliding plate 603 is fixedly connected to the bottom of the air duct 601, and a receiving box 604 is fixedly connected to the outer wall of the welding base 1 at the bottom of the sliding plate 603.

[0057] The welded shaving blade is transported by the positioning turntable 501 to the bottom of the air duct 601. When the cross-section of the air duct 601 is not sealed by the closing circular plate 606 and the closing ring plate 607, the airflow discharged from the air duct 601 will blow the shaving blade on the positioning turntable 501 into the inside of the sliding plate 603, and the shaving blade will slide into the inside of the receiving box 604 through the sliding plate 603 to discharge the completed welded shaving blade.

[0058] At the top of the welding platform 2, a heat sink 609 is fixedly connected to the bottom of the welding head 4. An inhalation notch 610 is formed on the outer wall of the sliding plate 603 close to the heat sink 609, and the heat sink 609 has good thermal conductivity.

[0059] When the shaving blade is transported by the positioning turntable 501 to the bottom of the welding head 4, the shaving blade will be transported to the top of the heat sink 609. When the exhaust fan 504 discharges the gas inside the exhaust box 503 outward, an inhaled airflow will be generated at the inhalation notch 610. Then, a flowing airflow will be generated at the inhalation notch 610, which can enable the heat sink 609 to dissipate heat from the shaving blade during welding, preventing the shaving blade from deforming due to the diffusion of welding heat and affecting the final quality.

[0060] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
