[0034] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] Referring to Figures 1-5 as shown, the present invention provides a multi-station intermediate frequency welding machine capable of automatic blanking, comprising:

[0036] a welding mechanism 1, the welding mechanism 1 includes a frame 10 and a welding assembly 11, the welding assembly 11 is arranged on the frame 10, and the welding assembly 11 is used for welding the workpieces.

[0037] a placement table 2, arranged on the frame 10, the placement table 2 has at least one placement rack 20, the placement rack 20 is used for placing the workpieces, and a rotating mechanism 3 is arranged between the placement table 2 and the frame 10; the rotating mechanism 3 is used for driving the placement table 2 to rotate on its own axis on the frame 10, so that the workpieces on the placement rack 20 can move sequentially along a preset route, without the need for workers to move the positions of the workpieces, and the workers only need to stand at the starting end of the preset route to complete the feeding.

[0038] a transfer mechanism 4, including a first bracket 40 and a grasping assembly 41, the first end of the first bracket 40 is arranged on the frame 10, the second end of the first bracket 40 is suspended above the placement table 2, the grasping assembly 41 is arranged below the second end of the first bracket 40, and the grasping assembly 41 transfers the workpieces on the placement rack 20 out of the placement table 2; there are a first preset position and a second preset position on the preset path, the welding assembly 11 is arranged corresponding to the first preset position, and the grasping assembly 41 is arranged corresponding to the second preset position. When the workpiece moves to the first preset position, the welding assembly 11 completes the welding work on the workpiece, and the welded workpiece will move to the second preset position. At this time, the grasping assembly 41 grabs the workpiece and transfers it out of the placement table 2, thereby realizing the automatic blanking of the workpiece. Workers do not need to manually blank, which not only saves time, but also avoids scalding or scratching the hands by the just-welded workpieces;

[0039] Those skilled in the art should know that connecting the grasping assembly 41 to the welding mechanism 1 through the first bracket 40 is for better setting up the device and ensuring that the grasping assembly 41 accurately corresponds to the second preset position. In fact, the transfer mechanism 4 can also exist independently, as long as it is ensured that the grasping assembly 41 corresponds to the second preset position to avoid inaccurate transfer of the workpiece due to position deviation. In addition, the positioning and detection technologies for the first preset position and the second preset position are all prior arts and will not be elaborated here.

[0040] The conveying mechanism 5 is arranged on one side of the placing table 2. The conveying mechanism 5 conveys the welded parts transferred out by the grasping component 41. In order to complete the blanking process more efficiently, the conveying mechanism 5 is arranged to receive the welded parts transferred out by the grasping component 41, and can transfer the welded parts at a constant speed to avoid the just-completed welded parts piling up together.

[0041] In a feasible implementation manner, refer to Figures 1-2 , in order to transfer the welded parts from the placing table 2 to the conveying mechanism 5, the grasping component 41 includes a first driving member 410, a second driving member 411 and a suction member 412. The first driving member 410 is arranged below the second end of the first bracket 40. The second driving member 411 is arranged on the first driving member 410. The suction member 412 is arranged on the second driving member 411. The first driving member 410 drives the second driving member 411 to reciprocate horizontally. The second driving member 411 drives the suction member 412 to reciprocate vertically. The second driving member 411 drives the suction member 412 downward until it contacts the welded part. The suction member 412 adsorbs the welded part. The second driving member 411 moves upward to separate the welded part from the placing rack 20. The first driving member 410 drives the second driving member 411 to move horizontally, thereby transferring the welded part from above the placing table 2 to above the conveying mechanism 5. The second driving member 411 moves downward until it contacts the conveying mechanism 5. At this time, the suction member 412 releases the adsorption of the welded part. The welded part is transported by the conveying mechanism 5 to the next link. The grasping component 41 resets above the placing table 2 to continue the next transfer action.

[0042] In this embodiment, refer to Figure 4 , the conveying mechanism 5 includes a second bracket 50, a conveyor belt assembly 51 and a third driving member 52. The conveyor belt assembly 51 is arranged on the second bracket 50. The third driving member 52 is arranged on one side of the second bracket 50. The output end of the third driving member 52 is connected to the conveyor belt assembly 51. The conveyor belt assembly 51 conveys the welded parts. Since the conveyor belt assembly 51 has a certain length, multiple welded parts can be conveyed at the same time, reducing the collection time after the welded parts are blanked. And the welded parts can be transported at a constant speed through the conveyor belt assembly 51, avoiding the welded parts directly falling into the collection place and causing accumulation and damage. The conveyor belt assembly 51 can be a plate conveyor belt or a belt conveyor belt. The third driving member in this embodiment can be a belt motor.

[0043] In a feasible implementation manner, refer to Figures 3-4, a collecting component 6 is arranged on the side of the conveyor belt component 51 away from the placing table 2. The collecting component 6 includes a feeding plate 60 and a collecting box 61. One end of the feeding plate 60 is placed on the second bracket 50, and the other end of the feeding plate 60 is connected to the collecting box 61 in an inclined downward manner. When the welded part is conveyed to the end of the conveyor belt component 51, it can slide down from the inclined feeding plate 60 into the collecting box 61 for centralized collection. In order to facilitate the workers to carry the welded part, pulleys can also be arranged at the bottom of the collecting box 61 to facilitate the movement of the collecting box 61. The feeding plate 60 is placed on the second bracket 50 and does not contact the conveyor belt component 51 to avoid affecting the normal operation of the conveyor belt component 51. The inclined feeding plate 60 can prevent the welded part from colliding and being damaged due to the height difference when falling into the collecting box 61.

[0044] In this embodiment, referring to Figure 1 and Figure 3 , in order to increase the stability of the conveyor belt component 51, a third bracket 7 is arranged between the second bracket 50 and the frame 10 to connect the conveying mechanism 5 and the frame 10 together, which can not only make the conveying mechanism 5 more stable, but also ensure that the transfer mechanism 4 will not cause the welded part to fall due to position deviation when transferring the welded part to the conveying mechanism 5.

[0045] In a feasible implementation manner, referring to Figure 2 , the adsorbing part 412 includes a connecting plate 4120 and an electromagnet 4121. The connecting plate 4120 is connected to the output shaft of the second driving part 411. The electromagnets 4121 are arranged at the four corners of the bottom of the connecting plate 4120. The second driving part 411 can be a double-rod cylinder. The output shaft of the second driving part 411 moves up and down to make the electromagnet 4121 contact the welded part, and the adsorption and detachment of the welded part are completed through the power-on and power-off of the electromagnet 4121.

[0046] In this embodiment, referring to Figures 1-2 , the first driving part 410 includes a guide rail cylinder. The guide rail cylinder drives the second driving part 411 to reciprocate horizontally to realize the transfer of the welded part from the placing table 2 to the conveying mechanism 5. The guide rail cylinder has high precision, smoother sliding, improves the service life of the equipment, and limit screws are arranged at both ends of the guide rail, and the stroke can be adjusted, and the stroke distance can be set for different welded parts.

[0047] In this embodiment, referring to Figure 5, the rotating mechanism 3 includes a rotating shaft 30 and a fourth driving member 31. The output end of the rotating shaft 30 is connected to the center of the bottom of the placing table 2, and the output end of the fourth driving member 31 is connected to the rotating shaft 30. The rotating mechanism 3 enables the placing rack 20 to move along a preset path, so that the welded parts pass through the feeding position, the first preset position, and the second preset position in sequence, avoiding multiple manual movements by workers, reducing the work process. Workers only need to stand at the feeding position to place the welded parts. To facilitate workers to control the picking and placing of the welded parts, a foot switch can also be set. The output end of the foot switch is connected to the control circuit inside the welding mechanism 1, and the start and stop of the welding component 11 and the rotating mechanism 3 are controlled by the workers.

[0048] In a feasible implementation manner, refer to Figure 5 , three placing racks 20 are provided. The three placing racks 20 are arranged circumferentially around the rotating shaft 30. Multi-station welding is achieved through multiple placing racks 20. Workers can place multiple welded parts at one time. After starting the welding machine, the welding component 11 welds the welded parts in sequence, and the transfer mechanism 4 picks up the welded parts in sequence, thereby improving work efficiency, reducing the start and stop of the welding machine, and extending the service life of the welding machine.

[0049] Based on the above embodiments, the working process of the present utility model is as follows: Workers control the rotating mechanism 3 on one side of the welding component 11 to complete feeding at multiple stations in sequence, turn on the welding machine, and the rotating mechanism 3 drives the placing table 2 to rotate, so that the welded parts on the placing rack 20 pass through the first preset position and the second preset position along the preset path in sequence. When the welded part reaches the first preset position, the welding component 11 at the corresponding position welds it. When the welded part reaches the second preset position, the second driving member 411 at the corresponding position drives the adsorbing member 412 downward. After the adsorbing member 412 adsorbs the welded part, the second driving member 411 rises. The first driving member 410 drives the second driving member 411 to move horizontally, and transfers it from above the placing table 2 to above the conveying mechanism 5. At this time, the second driving member 411 moves downward. When it touches the conveyor belt assembly 51, the adsorbing member 412 releases the adsorption of the welded part, and the welded part automatically falls onto the conveyor belt assembly 51 and is conveyed to the end of the conveyor belt assembly 51. Under the action of gravity, the welded part moves towards the feeding plate 60 and slides into the collection box 61 through the feeding plate 60. When the welded parts in the collection box 61 are full, the worker completes the collection of the welded parts at one time.

[0050] The structure, features, and function effects of the present utility model have been described in detail based on the embodiments shown in the drawings. The above is only the preferred embodiment of the present utility model, but the present utility model is not limited to the implementation scope shown in the drawings.
