Description

Technical Field

[0001] The invention belongs to the technical field of medical device welding, in particular to a vacuum suction welding all-in-one machine. Background Art

[0002] Brackets are small devices fixed on the surface of teeth to help correct the position of teeth. The main function of brackets is to connect teeth to archwires and move teeth by applying force to gradually achieve the ideal arrangement.

[0003] For example, the utility model with publication number CN202824966U discloses a dental orthodontic split bracket welding system, including a positioning plate, an insulating material positioning base, an upper electrode and a lower electrode, wherein the positioning plate is located on the insulating material positioning base, and the lower electrode is perpendicular to the insulating material positioning base; the upper electrode and the lower electrode are symmetrically arranged, and the positioning plate is a hinge structure. Compared with the prior art, the dental orthodontic split bracket welding system of the utility model has good orthodontic effect, no desoldering, high production yield, and convenient operation.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 8 As shown, the present invention provides a vacuum suction welding machine, comprising an outer box 1, a moving assembly 2 is movably connected inside the outer box 1, a first hydraulic rod 3 is fixedly connected inside the outer box 1, and a vacuum pump 4 is fixedly connected to the top of the outer box 1;

[0038] The moving assembly 2 includes a square block 21, a rotating shaft 22 is movably connected to the middle of the square block 21, a first gear 23 is fixedly connected to one end of the rotating shaft 22, and a first tooth plate 24 is fixedly connected to the inside of the outer box 1;

[0039] The interior of the rotating shaft 22 is movably connected with a suction assembly 5, one side of the square block 21 is fixedly connected with a sliding assembly 6, the interior of the outer box 1 is movably connected with a pushing assembly 7, a welding assembly 8 is arranged inside the outer box 1, and a collecting tray 9 is movably connected to one side of the outer box 1 close to the welding assembly 8;

[0040] The suction assembly 5 includes a support block 51, a vacuum suction cup 52 is fixedly connected to the interior of the support block 51, and an air pipe 53 connected to the support block 51 is fixedly connected to the output end of the vacuum pump 4;

[0041] The sliding assembly 6 includes a limit block 61 fixedly connected to the square block 21, and a second tooth plate 62 is movably connected inside the limit block 61. A guide groove 65 is formed on the inner wall of the outer box 1 near the sliding assembly 6.

[0042] The welding assembly 8 includes a high-pressure gas cylinder 81 , one end of which is provided with a valve 82 , a nozzle 83 and a second hydraulic rod 85 are fixedly connected inside the outer box 1 , and one end of the second hydraulic rod 85 is fixedly connected to a laser welding head 86 .

[0043] The above scheme is adopted: the square block 21 is moved up to drive the first gear 23 to engage with the first tooth plate 24, so that the first gear 23 drives the rotating shaft 22 to rotate counterclockwise by ninety degrees, and then drives the vacuum suction cup 52 and the bracket to rotate toward the welding assembly 8 through the support block 51. Through the cooperation between the high-pressure gas cylinder 81 and the nozzle 83, the laser welding head 86 welds the bracket while the nozzle 83 sprays the argon gas inside the high-pressure gas cylinder 81 to the welding area through the delivery pipe 84, 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.

[0044] like Figures 4 to 6 , Figure 8As shown, the pushing assembly 7 includes a rotating cylinder 71, the inner wall of which is annularly provided with a slide groove 72, the outer wall of which is fixedly connected to a second gear 73, and the interior of the rotating cylinder 71 is movably connected to a push rod 74, which passes through the outer wall of the outer box 1 and extends to the outside of the outer box 1, and one end of the push rod 74 is provided with a convex rod movably engaged with the inside of the slide groove 72. The slide groove 72 is composed of two arc grooves with an arc of 180 degrees and two transverse grooves with an arc of zero degrees. The two ends of the transverse groove are respectively connected to the two inclined grooves, and the side wall of the outer box 1 is provided with two blocks for circumferentially limiting the push rod 74, and the upper and lower sides of the push rod 74 away from the end of the rotating cylinder 71 are fixedly connected to the fourth spring piece 75, and the push rod 74 is elastically connected to the block on the side wall of the outer box 1 through the fourth spring piece 75.

[0045] The above scheme is adopted: through the design of the fourth spring piece 75, its function is that when the push rod 74 moves toward the direction of the suction component 5, the two fourth spring pieces 75 will be compressed. Therefore, when the rotating drum 71 rotates one hundred and eighty degrees, the protruding rod on the push rod 74 will be driven to slide to the inside of the horizontal groove of the slide groove 72. At this time, the push rod 74 will move toward the direction of the rotating drum 71 under the action of the elastic force of the fourth spring piece 75, thereby resetting, which is convenient for the next use and ensures the normal operation of the device.

[0046] like Figure 3 to Figure 4 , Figure 8 As shown, the end of the second tooth plate 62 away from the pushing assembly 7 is fixedly connected to the second elastic piece 63, and the second tooth plate 62 is elastically connected to the limit block 61 through the second elastic piece 63. One side of the second tooth plate 62 is fixedly connected to a round rod 64 that is movably clamped in the guide groove 65. The guide groove 65 is trapezoidal, and the inner part of the outer box 1 is movably connected to an inclined block 66. In the initial state, the inclined block 66 is located inside the top of the guide groove 65, and the bottom end of the inclined block 66 is in the shape of an inclined surface. The end of the inclined block 66 away from the guide groove 65 is fixedly connected to a third elastic piece 67 fixedly connected to the outer box 1. The third elastic piece 67 is used to squeeze the inclined block 66 and keep the inclined block 66 moving downward.

[0047] Adopt the above scheme: through the instructions attached Figure 4 It can be seen that the guide groove 65 includes a first vertical groove with a shorter length and a second vertical groove with a longer length, and the round rod 64 is movably connected to the inside of the first vertical groove in the initial state. When the round rod 64 slides along the first vertical groove to the inside of the inclined groove, it will abut against the inclined surface at the bottom end of the inclined block 66, thereby squeezing the inclined block 66 to shrink to the inside of the outer box 1, and then smoothly slide into the inside of the second vertical groove. At the same time, the inclined block 66 will reset under the elastic force of the third spring piece 67, and then block the inclined groove, thereby preventing the round rod 64 from sliding back into the slide groove when moving downward, affecting the normal operation of the device;

[0048] Through the design of the second spring piece 63, its function is that when the round rod 64 slides to the bottom end of the second vertical groove, the second gear 73 has rotated one hundred and eighty degrees. Subsequently, the second spring piece 63 will drive the round rod 64 to move in the direction of the first vertical groove under the action of the pulling force of the second tooth plate 62, and then the second tooth plate 62 drives the round rod 64 to reset, thereby preventing the second tooth plate 62 from meshing with the second gear 73 when moving up, driving the second gear 73 to rotate in the opposite direction, and affecting the normal operation of the device.

[0049] like Figure 1 to Figure 2 , Figure 5 , Figure 7 As shown, a first spring piece 54 is fixedly connected to a side of the support block 51 away from the air pipe 53, and the support block 51 is elastically connected to the square block 21 through the first spring piece 54. The top of the first hydraulic rod 3 is fixedly connected to the square block 21. After the square block 21 moves up, it drives the first gear 23 to engage with the first tooth plate 24, and makes the first gear 23 rotate counterclockwise ninety degrees. One end of the air pipe 53 away from the vacuum pump 4 is movably engaged with the support block 51, and a cylinder for limiting the air pipe 53 is provided on the top of the outer box 1. When the support block 51 rotates, the air pipe 53 remains stationary under the action of the cylinder limit. A delivery pipe 84 is provided inside the outer box 1, and the two ends of the delivery pipe 84 are respectively connected to the valve 82 and the nozzle 83. A button 10 for controlling the opening and closing of the valve 82 is provided on the top of the outer box 1, and the button 10 is located directly above the square block 21.

[0050] The above solution is adopted: through the design of the first spring sheet 54, its function is that when the push rod 74 releases the squeeze on the support block 51, at this time, the support block 51 will drive the vacuum suction cup 52 to reset under the action of the elastic force of the first spring sheet 54, thereby facilitating the next vacuum suction operation;

[0051] The button 10 is designed so that when the square block 21 moves down and the button 10 is released, the button 10 disconnects the circuit inside the outer box 1, and then drives the valve 82 to close through an electrical signal, so that the nozzle 83 stops jetting, thereby preventing the waste of argon gas.

[0052] The working principle and use process of the present invention are as follows: the operator places the tooth bracket to be welded just below the support block 51, and then starts the first hydraulic rod 3 and the vacuum pump 4 to move the working medium in the vacuum pump 4, and then forms a negative pressure at the bottom of the vacuum suction cup 52 through the air pipe 53, so that the tooth bracket is tightly adsorbed on the bottom of the vacuum suction cup 52. The first hydraulic rod 3 drives the moving component 2 to move upward as a whole, and is movably connected to the inside of the rotating shaft 22 through the support block 51, so that the vacuum suction cup 52 drives the tooth bracket to move together;

[0053] After the square block 21 moves upward, it drives the first gear 23 to mesh with the first tooth plate 24, so that the first gear 23 drives the rotating shaft 22 to rotate counterclockwise by ninety degrees. While the rotating shaft 22 rotates, it drives the suction component 5 inside it to rotate in the same direction, so that the vacuum suction cup 52 drives the bracket to rotate to the side close to the welding component 8. When the square block 21 moves to the top, the operator drives the laser welding head 86 to operate through the external operation panel, so that the bracket is welded by the laser welding head 86. After the square block 21 moves to the top, it will also abut against the button 10. When the button 10 is pressed, the circuit inside the outer box 1 will be closed, thereby generating an electrical signal, and the electrical signal will be transmitted to the valve 82, so that the coil in the valve 82 is energized 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 inside of the nozzle 83 through the delivery pipe 84, and the argon gas 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] When the square block 21 moves upward, it also drives the limit block 61 and the second tooth plate 62 inside it to move upward. When the second tooth plate 62 moves upward, it drives the round rod 64 to slide along the first vertical groove of the guide groove 65. When the square block 21 slides to the top, the round rod 64 slides to the inside of the second vertical groove of the guide groove 65 through the inclined groove, and drives the second tooth plate 62 to move toward the direction of the push component 7. When the square block 21 moves downward, the round rod 64 drives the second tooth plate 62 to move downward along the trajectory of the second vertical groove of the guide groove 65, so that the second tooth plate 62 is meshed with the second gear 73, and drives the second gear 73 to rotate 180 degrees.

[0056] When the second gear 73 rotates, it drives the protruding rod at one end of the push rod 74 to slide along the trajectory of the arc groove of the slide groove 72. Since the block limits the circumferential position of the push rod 74, the push rod 74 can only move along the trajectory of the arc groove toward the suction component 5, thereby abutting against the support block 51 and pushing the support block 51 and the vacuum suction cup 52 at the bottom thereof to move toward the collection tray 9. During the movement of the vacuum suction cup 52, 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 bracket, and then the vacuum suction cup 52 moves and drives the welded bracket to fall into the interior of the collection tray 9, thereby facilitating the unloading and collection of materials.
