[0043] The above scheme is adopted: after the square block 21 moves upwards, the first gear 23 is engaged with the first toothed plate 24, so that the first gear 23 drives the rotating shaft 22 to rotate counterclockwise by ninety degrees, and then the supporting block 51 drives the vacuum suction cup 52 and the dental bracket to rotate towards the welding assembly 8, through the cooperation between the high-pressure gas cylinder 81 and the spray head 83, so that the laser welding head 86 is welded to the dental bracket, and the spray head 83 sprays the argon in the high-pressure gas cylinder 81 to the welding area through the conveying pipe 84, so as to form a protective gas curtain during the welding process, prevent the welding area from being oxidized, and effectively improve the quality of vacuum suction welding.

[0044] As Figures 4 to 6 , Figure 8As shown, the pushing assembly 7 comprises a rotating drum 71, the inner wall of the rotating drum 71 is annularly provided with a sliding groove 72, the outer wall of the rotating drum 71 is fixedly connected with a second gear 73, the inside of the rotating drum 71 is movably connected with a push rod 74, the push rod 74 penetrates through the outer wall of the outer box 1 and extends to the outside of the outer box 1, one end of the push rod 74 is provided with a protruding rod movably clamped in the sliding groove 72, the sliding groove 72 is composed of two arc grooves with an angle of one hundred and eighty degrees and two horizontal grooves with an angle of zero degrees, the two ends of the horizontal grooves are respectively communicated with the two inclined grooves, the side wall of the outer box 1 is provided with two clamping blocks for circumferentially limiting the push rod 74, the upper and lower sides of the end of the push rod 74 away from the rotating drum 71 are fixedly connected with fourth elastic sheets 75, and the push rod 74 is elastically connected with the clamping blocks of the side wall of the outer box 1 through the fourth elastic sheets 75.

[0045] By adopting the above scheme, the fourth elastic sheet 75 is designed, and the fourth elastic sheet 75 is compressed when the push rod 74 moves towards the sucking assembly 5, so that when the rotating drum 71 rotates one hundred and eighty degrees, the protruding rod on the push rod 74 slides to the inside of the horizontal groove of the sliding groove 72, at this time, the push rod 74 moves towards the rotating drum 71 under the action of the elasticity of the fourth elastic sheet 75, so as to be reset, thereby facilitating the next use and ensuring the normal operation of the device.

[0046] As shown in Figures 3 to 4 , Figure 8 As shown, the second toothed plate 62 is fixedly connected with a second elastic sheet 63 at the end away from the pushing assembly 7, the second toothed plate 62 is elastically connected with the limiting block 61 through the second elastic sheet 63, one side of the second toothed plate 62 is fixedly connected with a round rod 64 movably clamped in the inside of a guide groove 65, the guide groove 65 is in a trapezoidal shape, the inside of the outer box 1 is movably connected with an inclined block 66, the inclined block 66 is located in the inside of the top end of the guide groove 65 in the initial state, the bottom end of the inclined block 66 is in a bevel shape, the end of the inclined block 66 away from the guide groove 65 is fixedly connected with a third elastic sheet 67 fixed to the outer box 1, and the third elastic sheet 67 is used for pressing the inclined block 66 and making the inclined block 66 keep the trend of moving downwards.

[0047] By adopting the above scheme, it can be seen from the description and drawings of the specification Figure 4 It can be seen that the guide groove 65 comprises a first vertical groove with a relatively short length and a second vertical groove with a relatively long length, and the round rod 64 is movably clamped in the inside of the first vertical groove in the initial state, when the round rod 64 slides to the inside of the inclined groove along the first vertical groove, the round rod 64 abuts against the inclined surface at the bottom end of the inclined block 66, so as to press the inclined block 66 to shrink to the inside of the outer box 1, thereby smoothly sliding into the inside of the second vertical groove, at the same time, the inclined block 66 is reset under the action of the elasticity of the third elastic sheet 67, thereby shielding the inclined groove, so as to prevent the round rod 64 from sliding into the sliding groove again when moving downwards, thereby affecting the normal operation of the device.

[0048] Through the design of the second elastic sheet 63, when the round rod 64 slides to the bottom end of the second vertical slot, at this time the second gear 73 has rotated 180 degrees, then the second elastic sheet 63 is driven by the pulling force of the second toothed plate 62 to move the round rod 64 in the direction of the first vertical slot, thereby making the second toothed plate 62 drive the round rod 64 to reset, so as to prevent the second toothed plate 62 from moving upward to engage with the second gear 73, drive the second gear 73 to rotate reversely, and affect the normal operation of the device.

[0049] As shown in Figures 1 to 2 、 Figure 5 、 Figure 7 The side of the supporting block 51 away from the air pipe 53 is fixedly connected with a first elastic sheet 54, the supporting block 51 is elastically connected with the square block 21 through the first elastic sheet 54, the top end of the first hydraulic rod 3 is fixedly connected with the square block 21, the square block 21 moves upward to drive the first gear 23 to engage with the first toothed plate 24, and make the first gear 23 rotate counterclockwise by 90 degrees, one end of the air pipe 53 away from the vacuum pump 4 is movably connected with the supporting block 51, the top of the outer box 1 is provided with a cylinder for limiting the air pipe 53, the air pipe 53 remains stationary under the limiting action of the cylinder when the supporting block 51 rotates, the inside of the outer box 1 is provided with a conveying pipe 84, both ends of the conveying pipe 84 are respectively connected with the valve 82 and the spray head 83 in communication, the top of the outer box 1 is provided with a button 10 for controlling the opening and closing of the valve 82, and the button 10 is located directly above the square block 21.

[0050] By adopting the above scheme: through the design of the first elastic sheet 54, when the push rod 74 removes the extrusion on the supporting block 51, at this time the supporting block 51 drives the vacuum chuck 52 to reset under the elastic force of the first elastic sheet 54, thereby facilitating the next vacuum suction operation;

[0051] Through the design of the button 10, when the square block 21 moves downward to remove the pressing on the button 10, at this time the button 10 makes the circuit inside the outer box 1 disconnected, thereby driving the valve 82 to close through the electric signal, so that the spray head 83 stops the gas spraying operation, preventing the waste of argon gas.

[0052] The working principle and use process of the present application are as follows: the operator places the tooth bracket to be welded directly below the supporting block 51, then starts the first hydraulic rod 3 and the vacuum pump 4, so that the working medium in the vacuum pump 4 moves, thereby forming negative pressure at the bottom of the vacuum chuck 52 through the air pipe 53, so that the tooth bracket is tightly adsorbed on the bottom of the vacuum chuck 52, the first hydraulic rod 3 moves upward while driving the moving assembly 2 to move upward as a whole, and the supporting block 51 is movably connected in the inside of the rotating shaft 22, so that the vacuum chuck 52 drives the tooth bracket to move together;

[0053] When the square block 21 moves up, the first gear 23 is engaged with the first toothed plate 24, so that the first gear 23 drives the rotating shaft 22 to rotate counterclockwise by 90 degrees. At the same time, the rotating shaft 22 drives the suction assembly 5 inside to rotate in the same direction, so that the vacuum suction cup 52 drives the dental bracket to rotate to the side close to the welding assembly 8. When the square block 21 moves to the top end, the operator operates the external operation panel, so that the second hydraulic rod 85 drives the laser welding head 86 to operate, thereby welding the dental bracket through the laser welding head 86. After the square block 21 moves to the top end, it abuts against the button 10. When the button 10 is pressed, the circuit inside the outer box 1 is closed, thereby generating an electrical signal, which is transmitted to the valve 82, so that the coil in the valve 82 is electrified to generate a magnetic field, attracting the valve core to move, thereby controlling the valve 82 to open;

[0054] After the valve 82 is opened, the argon gas in the high-pressure gas cylinder 81 is transported to the nozzle 83 through the conveying pipe 84, and is sprayed to the welding area through the nozzle 83, thereby forming a protective gas curtain during the welding process to prevent the welding area from being oxidized, thereby effectively improving the quality of vacuum suction welding;

[0055] At the same time, the square block 21 moves up, driving the limiting block 61 and the second toothed plate 62 inside to move up. At the same time, the second toothed plate 62 moves up, driving the circular rod 64 to slide along the first vertical slot of the guide slot 65. When the square block 21 slides to the top end, the circular rod 64 slides through the inclined slot to the inside of the second vertical slot of the guide slot 65, and at the same time drives the second toothed plate 62 to move in the direction of the pushing assembly 7. When the square block 21 moves down, the circular rod 64 drives the second toothed plate 62 to move down along the track of the second vertical slot of the guide slot 65, so that the second toothed plate 62 is engaged with the second gear 73, and drives the second gear 73 to rotate by 180 degrees.

[0056] At the same time, the second gear 73 rotates, driving the protruding rod at one end of the push rod 74 to slide along the track of the arc slot of the sliding slot 72. Since the clamping block limits the circumference of the push rod 74, the push rod 74 can only move along the track of the arc slot in the direction of the suction assembly 5, so as to abut against the supporting block 51 and push the supporting block 51 and the vacuum suction cup 52 at the bottom thereof in the direction of the collecting disc 9. In the process of moving, the vacuum pump 4 releases the negative pressure state at the bottom of the vacuum suction cup 52 through the air pipe 53, so that the vacuum suction cup 52 releases the positioning of the dental bracket, and then the vacuum suction cup 52 moves to drive the welded dental bracket to fall into the inside of the collecting disc 9, thereby achieving the effect of convenient discharging and collecting.
