For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features / embodiments in the present invention will not be described separately.

[0048] like Figure 1 and Figure 2 As shown, an automatic welding device provided by an embodiment of the present invention comprises a workbench 1, a slide assembly 2, a steel handle feeding mechanism 3, a steel handle welding working mechanism 4, a welding mechanism 5, an alloy feeding mechanism 6, an alloy welding working mechanism 7 and a receiving mechanism 8. The slide assembly 2 is slidably connected to the workbench 1, and the slide assembly 2 is provided with a steel handle welding working mechanism 4. The steel handle feeding mechanism 3, the welding mechanism 5, the alloy feeding mechanism 6, the alloy welding working mechanism 7 and the receiving mechanism 8 are installed on the workbench 1. The steel handle welding working mechanism 4 and the alloy welding working mechanism 7 are located on both sides of the welding mechanism 5. The slide assembly 2 is used to drive the steel handle welding working mechanism 4 to approach or move away from the welding mechanism 5.

[0049] like Figure 3 and Figure 4As shown, the steel handle welding working mechanism 4 includes a steel handle feeding assembly 41, a steel handle pushing assembly 42 and a steel handle pressing assembly 43. The steel handle feeding mechanism 3 is used to arrange the steel handles 101 in order and convey them to the steel handle feeding assembly 41. The steel handle feeding assembly 41 is used to convey the steel handle 101 to the steel handle pushing assembly 42. The steel handle pushing assembly 42 is used to push the steel handle 101 to the welding position. The steel handle pressing assembly 43 is used to press the steel handle 101 at the welding position.

[0050] like Figure 5 , Fig. 9 and Fig.10 As shown, the alloy welding working mechanism 7 includes an alloy feeding assembly 71, an alloy top assembly 72, an alloy pressing assembly 73, a flux feeding assembly 74 and a welding wire feeding assembly 75. The alloy feeding mechanism 6 is used to arrange the alloy materials 102 in order and convey them to the alloy feeding assembly 71. The alloy feeding assembly 71 is used to convey the alloy materials 102 to the alloy top assembly 72. The alloy top assembly 72 pushes the alloy materials 102 to move so that the alloy materials abut against the steel handle at the welding position. The alloy pressing assembly 73 is used to press the alloy materials 102 abutting against the steel handle 101 (such as Figure 8 As shown in the figure, the welding mechanism 5 is used to weld the abutment between the steel handle and the alloy material to form a medical dental tool semi-finished product, and in the process of the alloy top material component 72 pushing the alloy material toward the steel handle, the flux feeding component 74 is used to provide flux for the alloy material, and the welding wire feeding component 75 is used to provide welding wire for the alloy material, and the welding wire is attached (bonded) to the welding end surface of the alloy material through the flux, and the receiving mechanism 8 is used to receive the medical dental tool semi-finished product after welding.

[0051] By setting the slide assembly 2 to drive the steel handle welding working mechanism 4 to move, the distance between the steel handle welding working mechanism 4 and the alloy welding working mechanism 7 can be controlled. When the welding is completed, the material receiving mechanism 8 can move between the steel handle welding working mechanism 4 and the alloy welding working mechanism 7 to facilitate the reception of the medical dental tool semi-finished product, so as to realize the automatic loading, welding and unloading of the steel handle and the alloy material, reduce the degree of operator participation in welding, thereby effectively reducing the work intensity and improving production efficiency.

[0052] In specific applications, the flux feeding assembly 74 can also be used to provide flux for the steel handle, and the welding wire feeding assembly 75 can also be used to provide welding wire for the steel handle. The welding wire is attached (bonded) to the welding end surface of the steel handle through the flux.

[0053] Alternatively, if Figure 3 , Figure 4 and Figure 6As shown, the steel handle feeding assembly 41 includes a steel handle pushing block 411, a first feeding driving member 412, a steel handle supporting seat 413 and a steel handle collecting box 414. The steel handle collecting box 414 is connected to the steel handle feeding mechanism 3 through a first conveying pipe 40. The steel handle pushing block 411 is arranged below the steel handle collecting box 414. A steel handle unloading port is arranged at the lower end of the steel handle collecting box 414. The steel handle pushing block 411 is provided with a steel handle containing groove 4111 below the steel handle unloading port (that is, after the steel handle enters the steel handle collecting box 414, the steel handle can directly fall into the steel handle through the steel handle unloading port). The steel handle support seat 413 is provided below the steel handle pushing block 411, and the steel handle support seat 413 is in contact with the steel handle pushing block 411. The steel handle support seat 413 may be provided with a first positioning groove 4131. The first feeding drive member 412 drives the steel handle pushing block 411 to move relative to the steel handle support seat 413, so that the steel handle material storage groove 4111 and the first positioning groove 4131 are connected, and the steel handle falls from the steel handle material storage groove 4111 into the first positioning groove 4131 below, that is, the steel handle material storage groove 4111 is a structure that is connected up and down in the vertical direction. When the steel handle material storage groove 4111 and the first positioning groove 4131 are misaligned, since the steel handle pushing block 411 is located on the steel handle support seat 413, the steel handle support seat 413 will block the lower end of the steel handle material storage groove 4111, thereby preventing the steel handle from falling out of the steel handle material storage groove 4111. When the steel handle pushing block 411 is connected to the first positioning groove 4131 , the steel handle pushing block 411 will block the steel handle unloading port.

[0054] In a specific application, before the first feeding drive component 412 is actuated, the steel handle material storage groove 4111 is offset from the steel handle material discharge port, and the steel handle pushing block 411 blocks the steel handle material discharge port, and when the first feeding drive component 412 drives the steel handle pushing block 411 to move toward the first positioning groove 4131, the steel handle material storage groove 4111 is first connected with the steel handle material discharge port, and the steel handle enters the steel handle material storage groove 4111, and the first feeding drive component 412 continues to drive the steel handle pushing block 411 to move toward the first positioning groove 4131, until the steel handle material storage groove 4111 is connected with the first positioning groove 4131, and the steel handle enters the first positioning groove 4131.

[0055] Specifically, the steel handle material collection box 414 includes two first side plates 4141, a first fixed end plate 4142 and a first movable end plate 4143. The two first side plates 4141 are arranged opposite to each other, the first fixed end plate 4142 is fixedly connected to the same end of the two first side plates 4141, and the first movable end plate 4143 is slidably connected between the two first side plates 4141 to adjust the length of the steel handle material collection box 414. The length of the steel handle material collection box 414 can be adjusted by the first movable end plate 4143 for steel handles of different lengths, so that the length of the steel handle material collection box 414 is adapted to the length of the steel handle, thereby meeting the welding requirements of steel handles of different lengths.

[0056] In some embodiments, the two first side plates and the first fixed end plate are a U-shaped integrated structure, and the U-shaped integrated structure remains stationary, and the length of the steel handle collection box can be adjusted by moving the first movable end plate.

[0057] In some embodiments, Fig.14 As shown, the first movable end plate 4143 is connected to one of the first side plates 4141 to form an L-shaped structure, and the first fixed end plate 4142 and the other first side plate 4141 remain fixed. The length of the steel handle collection box 414 can be adjusted by moving the L-shaped structure. Alternatively, the first fixed end plate remains fixed, and the other first side plate can be used as a replacement part. Multiple replacement parts (first side plates) with different lengths are configured, and the corresponding replacement parts are replaced as the distance between the first movable end plate and the first fixed end plate in the L-shaped structure changes.

[0058] Specifically, the first feeding driving member 412 can be a cylinder, the piston rod of the cylinder is connected to the steel handle pushing block 411, and the steel handle pushing block 411 is driven to move by controlling the extension and retraction of the cylinder piston rod.

[0059] Specifically, the steel handle containing groove 4111 can only accommodate one steel handle at a time.

[0060] Specifically, Figure 3 , Figure 4 and Figure 6 As shown, the first positioning groove 4131 can be set on a steel handle positioning block 4132. In this case, the steel handle support seat 413 is provided with a first installation groove for accommodating the steel handle positioning block 4132. The steel handle positioning block 4132 is detachably connected to the steel handle support seat 413 through the first installation groove. In practical applications, multiple steel handle positioning blocks 4132 with different sizes of first positioning grooves 4131 can be configured. In this way, when welding steel handles of different diameters, only the steel handle positioning blocks 4132 of corresponding sizes need to be replaced.

[0061] Specifically, the cross section of the first positioning groove 4131 may be V-shaped, U-shaped, or semicircular.

[0062] Alternatively, if Figure 3 and Figure 4 As shown, the steel handle ejection assembly 42 includes a first ejector pin 421 and a first ejection driving member 422. The first ejector pin 421 is arranged along the length direction of the first positioning groove 4131. The first ejection driving member 422 is used to drive the first ejector pin 421 to push the steel handle located in the first positioning groove 4131 to the welding position. When welding steel handles of different lengths, the distance that the first ejector pin 421 moves toward the steel handle can be adjusted to push the steel handles of different lengths to the welding position. The entire adjustment process is simple, rapid, and easy to use.

[0063] Specifically, Figure 3 and Figure 4 As shown, the first ejection drive member 422 can be a servo motor, which is installed on the slide assembly 2 through a servo fixed block 420. The output shaft of the servo motor is connected to the ejection screw rod 424 through a gear transmission mechanism 423. A sliding block 425 is threadedly connected to the ejection screw rod 424, and the sliding block 425 is also slidably connected to the slide assembly 2 through a guide rail 426, that is, the guide rail 426 is fixed on the slide assembly 2, wherein the first ejector pin 421 is fixed on the sliding block 425, and the sliding block 425 is driven to move along the guide rail 426 by controlling the forward and reverse rotation of the servo motor, thereby driving the first ejector pin 421 to move.

[0064] As another embodiment, the first ejector drive member 422 can also be a cylinder, the piston rod of the cylinder is connected to the sliding block 425, the sliding block 425 is also slidably connected to the slide assembly 2 through the guide rail 426, the first ejector pin 421 is fixed on the sliding block 425, and the sliding block 425 is driven to move along the guide rail 426 by controlling the extension and retraction of the cylinder piston rod, thereby driving the first ejector pin 421 to move.

[0065] Alternatively, if Figure 3 and Figure 4 As shown, the steel handle push-up assembly 42 further includes a first sensor 427, which can be arranged above the first positioning groove 4131, and is used to sense whether there is a steel handle in the first positioning groove 4131. When the first sensor 427 does not sense the presence of a steel handle in the first positioning groove 4131, the first sensor 427 feeds back the sensing result to the first feeding drive 412, and the first feeding drive 412 drives the steel handle pusher 411 to move and transport the steel handle to the first positioning groove 4131. If the first sensor 427 fails to sense the steel handle in the first positioning groove 4131 for five consecutive times, the automatic welding device is triggered to stop and alarm. In practical applications, the conditions for the first sensor 427 to trigger the automatic welding device to stop and alarm can be set according to actual conditions; when the first sensor 427 senses the presence of a steel handle in the first positioning groove 4131, the first sensor 427 feeds back the sensing result to the first push-up drive 422, and the first push-up drive 422 is actuated. The action of the first ejection driving member 422 is as follows: the first ejection driving member 422 drives the first ejector pin 421 to move toward the welding mechanism 5, pushes the steel handle in the first positioning groove 4131 to the welding position, and waits until the steel handle pressing assembly 43 presses the steel handle, and then the first ejection driving member 422 drives the first ejector pin 421 back to its original position, waiting for the next action.

[0066] Alternatively, if Figure 3 , Figure 4 and Figure 6As shown, the steel handle pressing assembly 43 includes a first pressing arm 431, a first mounting seat 432, a first pressing driving member 433 and a first pressing member 434. The middle part of the first pressing arm 431 is rotatably connected to the first mounting seat 432, one end of the first pressing arm 431 is connected to the first pressing member 434, and the other end of the first pressing arm 431 is connected to the output shaft of the first pressing driving member 433. The first pressing driving member 433 drives the first pressing arm 431 to rotate relative to the first mounting seat 432, so that the first pressing member 434 presses against the steel handle located at the welding position, wherein the first positioning groove 4131 extends to the bottom of the first pressing member 434, thereby ensuring the clamping effect on the steel handle located at the welding position.

[0067] Specifically, the first material pressing driving member 433 can be a cylinder, the piston rod of the cylinder is connected to the first pressing arm 431, and the first pressing arm 431 is driven to rotate relative to the first mounting seat 432 by controlling the extension and retraction of the cylinder piston rod, thereby controlling the first material pressing member 434 to press the alloy material or loosen the steel handle.

[0068] Alternatively, if Figure 7 , Fig. 9 , Fig.10 and Fig.11 As shown, the alloy feeding assembly 71 includes an alloy pushing block 711, a second feeding driving member 712, an alloy supporting seat 713 and an alloy collecting box 714. The alloy collecting box 714 is connected to the alloy feeding mechanism 6 through the second conveying pipe 70. The alloy pushing block 711 is arranged below the alloy collecting box 714. The lower end of the alloy collecting box 714 is provided with an alloy discharge port. The alloy pushing block 711 is provided with an alloy containing groove 7111 below the alloy discharge port (that is, after the alloy material enters the alloy collecting box 714, the alloy material can directly fall into the alloy through the alloy discharge port). The alloy support seat 713 is arranged below the alloy pusher block 711, and the alloy support seat 713 contacts the alloy pusher block 711. The alloy support seat 713 is provided with a second positioning groove 7131. The second feeding drive member 712 drives the alloy pusher block 711 to move relative to the alloy support seat 713, so that the alloy storage tank 7111 and the second positioning groove 7131 are connected, and the alloy material falls from the alloy storage tank 7111 into the second positioning groove 7131 below, that is, the alloy storage tank 7111 is a structure that is connected up and down in the vertical direction. When the alloy storage tank 7111 and the second positioning groove 7131 are misaligned, since the alloy pusher block 711 is located on the alloy support seat 713, the alloy support seat 713 will block the lower end of the alloy storage tank 7111, thereby preventing the alloy material from falling out of the alloy storage tank 7111. When the alloy pushing block 711 is connected to the second positioning groove 7131 , the alloy pushing block 711 will block the alloy discharge port.

[0069] In a specific application, before the second feeding drive member 712 is actuated, the alloy containing groove 7111 is offset from the alloy discharge port, and the alloy pushing block 711 blocks the alloy discharge port. When the second feeding drive member 712 drives the alloy pushing block 711 to move toward the second positioning groove 7131, the alloy containing groove 7111 is first connected with the alloy discharge port, and the alloy material enters the alloy containing groove 7111. The second feeding drive member 712 continues to drive the alloy pushing block 711 to move toward the second positioning groove 7131 until the alloy containing groove 7111 is connected with the second positioning groove 7131, and the alloy material enters the second positioning groove 7131.

[0070] Specifically, the alloy collection box 714 includes two second side plates, a second fixed end plate and a second movable end plate (not shown in the figure), the two second side plates are arranged opposite to each other, the second fixed end plate is fixedly connected to the same end of the two second side plates, and the second movable end plate is slidably connected between the two second side plates to adjust the length of the alloy collection box 714. For alloy materials of different lengths, the length of the alloy collection box 714 can be adjusted by the second movable end plate, so that the length of the alloy collection box 714 is adapted to the length of the alloy material. Among them, the structure of the alloy collection box 714 is similar to that of the steel handle collection box 414, and the role of the alloy collection box 714 is the same as that of the steel handle collection box 414. By adjusting the length of the steel handle collection box 414 and the alloy collection box 714, the welding of steel handles of different lengths and alloy materials of different lengths can be achieved.

[0071] Specifically, the second feeding driving member 712 may be a cylinder, the piston rod of which is connected to the alloy pushing block 711 , and the alloy pushing block 711 is driven to move by controlling the extension and retraction of the piston rod of the cylinder.

[0072] Specifically, the alloy material tank 7111 can only accommodate one alloy material at a time.

[0073] Specifically, Figure 7 , Figure 8 , Fig. 9 and Fig.11 As shown, the second positioning groove 7131 can be set on an alloy positioning block 7132. In this case, the alloy support seat 713 is provided with a second installation groove for accommodating the alloy positioning block 7132. The alloy positioning block 7132 is detachably connected to the alloy support seat 713 through the second installation groove. In practical applications, multiple alloy positioning blocks 7132 with different sizes of second positioning grooves 7131 can be configured. In this way, when welding alloy materials of different diameters, it is only necessary to replace the alloy positioning blocks 7132 of the corresponding size.

[0074] Specifically, the cross section of the second positioning groove 7131 may be V-shaped, U-shaped, or semicircular.

[0075] Alternatively, if Fig. 9 As shown, the alloy ejector assembly 72 includes a second ejector pin 721 and a second ejector driving member 722. The second ejector pin 721 is arranged along the length direction of the second positioning groove 7131. The second ejector driving member 722 is used to drive the second ejector pin 721 to push the alloy material in the second positioning groove 7131 to the welding position, so that the welding end face of the alloy material abuts against the welding end face of the steel handle. When welding alloy materials of different lengths, the distance that the second ejector pin 721 moves toward the alloy material can be adjusted to push the alloy materials of different lengths to the welding position, so that the welding end face of the alloy material abuts against the welding end face of the steel handle. The entire adjustment process is simple, rapid, and easy to use.

[0076] Specifically, Fig. 9 As shown, the second ejector driving member 722 may be a cylinder, and the second ejector pin 721 is connected to the piston rod of the cylinder through an ejector pin locking sleeve 723, and the second ejector pin 721 is driven to move by controlling the extension and retraction of the cylinder piston rod.

[0077] Alternatively, if Figure 7 , Fig. 9 and Fig.10 As shown, the alloy pusher assembly 72 further includes a second sensor 724, which can be disposed above the second positioning groove 7131, and is used to sense whether there is alloy material in the second positioning groove 7131. When the second sensor 724 does not sense the presence of alloy material in the second positioning groove 7131, the second sensor 724 feeds back the sensing result to the second feeding drive 712, and the second feeding drive 712 drives the alloy pusher block 711 to move and deliver the alloy material to the second positioning groove 7131. If the second sensor 724 fails to sense alloy material in the second positioning groove 7131 for five consecutive times, the automatic welding device is triggered to shut down and alarm. In actual applications, the conditions for the second sensor 724 to trigger the shutdown alarm of the automatic welding device can be set according to actual conditions; when the second sensor 724 senses that there is alloy material in the second positioning groove 7131, the second sensor 724 feeds back the sensing result to the second ejection drive 722, and the second ejection drive 722 drives the second ejector pin 721 to move toward the welding mechanism 5, pushing the alloy material in the second positioning groove 7131 toward the welding position, until the welding surface of the alloy material abuts against the welding surface of the steel handle, and the alloy pressing assembly 73 presses the alloy material.

[0078] Alternatively, if Figures 7 to 9As shown, the alloy pressing assembly 73 includes a second pressing arm 731, a second mounting seat 732, a second pressing driving member 733 and a second pressing member 734. The middle part of the second pressing arm 731 is rotatably connected to the second mounting seat 732, one end of the second pressing arm 731 is connected to the second pressing member 734, and the other end of the second pressing arm 731 is connected to the output shaft of the second pressing driving member 733. The second pressing driving member 733 drives the second pressing arm 731 to rotate relative to the second mounting seat 732, so that the second pressing member 734 presses the alloy material abutting against the steel handle. Among them, the second positioning groove 7131 extends to the bottom of the second pressing member 734, so as to ensure the pressing effect on the alloy material at the welding position.

[0079] Specifically, the second material pressing driving member 733 can be a cylinder, the piston rod of the cylinder is connected to the second pressing arm 731, and the second pressing arm 731 is driven to rotate relative to the second mounting seat 732 by controlling the extension and retraction of the cylinder piston rod, thereby controlling the second material pressing member 734 to press or loosen the alloy material.

[0080] Alternatively, if Fig.11 As shown, the alloy support seat 713 is connected to the flux fixing block 7133, and the flux fixing block 7133 is provided with a connecting hole 7134. The connecting hole 7134 is aligned with the second positioning groove 7131 so that the alloy material located in the second positioning groove 7131 can pass through the connecting hole 7134. The flux fixing block 7133 is also provided with a flux discharge hole 7135 and a welding wire discharge hole 7136. The flux discharge hole 7135 and the welding wire discharge hole 7136 are respectively connected with the connecting hole 7134, and along the length direction of the second positioning groove 7131, the welding wire discharge hole 7136 is located on the side close to the welding mechanism 5. The flux feeding assembly 74 and the welding wire feeding assembly 75 inject flux and welding wire into the connecting hole 7134 through the flux discharge hole 7135 and the welding wire discharge hole 7136 respectively. In the process of the alloy material passing through the connecting hole 7134, the welding surface of the alloy material first contacts with the flux, and the flux adheres to the welding end surface of the alloy material. As the alloy material continues to move toward the steel handle, the welding wire contacts the alloy material, and at the same time, the welding wire is bonded to the welding end surface of the alloy material through the flux. When the welding end surface of the alloy material is misaligned with the welding wire discharge hole 7136, the welding wire will be cut off by the welding end surface of the alloy material.

[0081] Alternatively, if Figure 7As shown, the flux feeding assembly 74 includes a welding gun 741, a welding gun fixing seat 742 and a flux feeding driving member 743. The welding gun 741 is used to hold the flux. The welding gun 741 is installed on the workbench 1 through the welding gun fixing seat 742, and the discharge port of the welding gun 741 is connected with the flux discharge hole 7135. The flux feeding driving member 743 controls the welding gun 741 to deliver the flux to the flux discharge hole 7135. Among them, the welding gun 741 can be a structure similar to a syringe, and the flux feeding driving member 743 is a cylinder. When the piston rod of the cylinder extends outward, the welding gun 741 can be squeezed to discharge the flux to the flux discharge hole 7135.

[0082] Alternatively, if Figure 7 and Fig. 9 As shown, the welding wire feeding assembly 75 includes a wire feeder 751 and a wire guide tube 752, and the wire feeder 751 and the welding wire discharge hole 7136 are connected through the wire guide tube 752.

[0083] Alternatively, if Figure 7 and Fig.10As shown, the alloy ejection assembly 72 further includes an ejection assembly 76, which includes a push plate 761, a guide rod 762 and an ejection driving member 763. The guide rod 762 is arranged along the length direction of the second positioning groove 7131. The push plate 761 is slidably connected with the guide rod 762. The ejection driving member 763 is used to drive the push plate 761 to slide along the guide rod 762. The second ejection driving member 722 is fixedly connected with the push plate 761 through the fixing plate 725. When the ejection driving member 763 is used to drive the push plate 761 to slide along the guide rod 762, the second ejection driving member 722 moves with the push plate 761. This arrangement can avoid the failure to cut the welding wire when the alloy material passes through the connecting hole 7134 due to insufficient power of the second ejection driving member 722. When the ejection assembly 76 is provided, the specific operation of the alloy ejection assembly 72 is as follows: when the second sensor 724 senses that there is alloy material in the second positioning groove 7131, the second sensor 724 feeds back the sensing result to the ejection driving member 763, and the ejection driving member 763 drives the push plate 761 to move toward the welding mechanism 5. The second ejection driving member 722 moves with the push plate 761, and the second ejector pin 721 gradually approaches the alloy material in the second positioning groove 7131. When the second ejector pin 721 contacts the alloy material, the second ejector pin 721 pushes the alloy material toward the welding mechanism 5. In the process of the alloy material moving toward the welding mechanism 5, the flux feeding assembly 74 and the welding wire feeding assembly 75 sequentially provide flux and welding wire to the alloy material, and when the alloy material cuts off the welding wire, the ejection driving member 763 stops moving, and at the same time, the second ejection driving member 722 is actuated to continue pushing the alloy material toward the welding mechanism 5 until the welding end face of the alloy material abuts against the welding end face of the steel handle.

[0102] The alloy feeding mechanism 6 is started, and the alloy material is conveyed to the alloy collecting box 714 through the second conveying pipe 70. The alloy material enters the alloy collecting box 714 and falls into the alloy containing groove 7111 below it through the alloy discharge port. The second feeding driving member 712 drives the alloy pushing block 711 to move, so that the alloy containing groove 7111 and the second positioning groove 7131 are connected, and the alloy material falls into the second positioning groove 7131. When the second sensor 724 senses that there is alloy material in the second positioning groove 7131, the second sensor 724 feeds back the sensing result to the breaking driving member 763, and the breaking driving member 763 drives the push plate 761 to move toward the steel handle along the guide rod 762. The alloy pushing assembly 72 moves with the push plate 761, and the second ejector pin 721 of the alloy pushing assembly 72 pushes the alloy material toward the steel handle. The alloy material passes through the connecting hole 7134 of the flux fixing block 7133, and the flux is The flux feeding assembly 74 and the welding wire feeding assembly 75 respectively transport the flux and the welding wire through the flux discharge hole and the welding wire discharge hole 7136. When the alloy material moves in the connecting hole 7134, the welding end face of the alloy material first contacts with the flux, and the flux adheres to the welding end face of the alloy material. Then, the welding wire is bonded to the welding end face of the alloy material through the flux. As the welding end face of the alloy material passes through the welding wire discharge hole 7136, the alloy material pushes the welding wire off, that is, the pushing driving member 763 drives the pushing plate 761 to move until the alloy material pushes the welding wire off and stops. Then, the second feeding driving member 712 drives the second ejector pin 721 to move, and will continue to push the alloy material toward the steel handle, and make the welding end face of the alloy material abut against the welding end face of the steel handle. Finally, the second pressing driving member 733 drives the second pressing arm 731 to rotate, so that the second pressing member 734 presses the alloy material against the welding end face of the steel handle.

[0103] S3, start the welding mechanism 5 to weld the abutment between the steel handle and the alloy material to obtain a semi-finished medical dental tool, wherein the alloy pressing component 73 releases the alloy material before the welding is completed, and the alloy pushing component 72 moves to push the alloy material toward the steel handle, and after the first set time, the alloy pressing component 73 presses the alloy material again, and after the welding mechanism 5 stops working, the steel handle pressing component 43 and the alloy pressing component 73 continue to press for a second set time and then release; the specific process is as follows:

[0104] Before the welding is finished (for example, 0.5s-1s before the welding is finished), the second material pressing driving member 733 drives the second pressing arm 731 to rotate, so that the second material pressing member 734 releases the alloy material, and at the same time, the second material pushing driving member 722 drives the second ejector pin 721 to push the alloy material toward the steel handle. After the first set time (for example, the second ejector pin 721 pushes the alloy material toward the steel handle for 0.5s-1s), the second material pressing driving member 733 drives the second pressing arm 731 to rotate, so that the second material pressing member 734 presses the alloy material again. The purpose of this operation is to expel the air between the welding end of the steel handle and the welding end face of the alloy material by squeezing, thereby ensuring To maintain the welding effect of the steel handle and the alloy material, after the welding mechanism 5 stops working, the first pressing piece 434 and the second pressing piece 734 continue to press the steel handle and the alloy material, and release them after the second set time (the first pressing piece 434 and the second pressing piece 734 are maintained for 0.5s-1s); or, after the welding mechanism 5 stops working, the first pressing piece 434 and the second pressing piece 734 continue to press the steel handle and the alloy material, and after the second set time, the second pressing piece 734 releases the alloy material, and the first pressing piece 434 continues to keep pressing the steel handle, ensuring that the semi-finished medical dental tool will not fall off the first positioning groove 4131 during subsequent operations.

[0105] In the above step S3, the time for the second pressing arm 731 to rotate and loosen the alloy material before the welding is completed, the duration for the second ejector pin 721 to push the alloy material toward the steel handle, and the duration for the first pressing member 434 and the second pressing member 734 to continue to press the steel handle and the alloy material after the welding mechanism 5 stops working can all be set according to specific circumstances.

[0106] S4, the slide assembly 2 and the alloy push-up assembly 72 return to their positions, then the slide assembly 2 moves to the unloading position, the receiving mechanism 8 moves to the receiving position (i.e., below the unloading position), the steel handle push-up assembly 42 moves to push the semi-finished medical dental tool out of the first positioning groove 4131, and the semi-finished medical dental tool falls into the receiving mechanism 8, the slide assembly 2, the steel handle push-up assembly 42 and the receiving mechanism 8 return to their positions, and repeat steps S1 to S4 for the next round of welding. The specific process is as follows:

[0107] The slide drive 22 drives the supporting slide 21 to move back along the slide rail, the ejector drive 763 drives the push plate 761 to move back along the guide rod 762, the second feeding drive 712 drives the second ejector pin 721 to move back, and then the slide drive 22 drives the supporting slide 21 to move along the slide rail to the unloading position, the material receiving drive 86 drives the material receiver 80 to move to the material receiving position (i.e., below the unloading position), the first ejector drive 422 drives the first ejector pin 421 to move, and pushes the semi-finished medical dental tool from the first positioning groove 4131, so that the semi-finished medical dental tool falls into the material receiver 81, and the semi-finished medical dental tool enters the collecting trough 85 through the material receiver 81. Next, the slide drive 22 drives the support slide 21 to move back along the slide rail, the first feeding drive 412 drives the first ejector 421 to move back, and the receiving drive 86 drives the receiving device 81 to move back, and steps S1 to S4 are repeated for the next round of welding.

[0108] In a specific application, when the slide drive 22 drives the supporting slide 1 to move along the slide rail to the unloading position, the first feeding drive 412 first drives the steel handle pushing block 411 to move, so that the steel handle material receiving groove 4111 and the first positioning groove 4131 are connected, and the steel handle falls into the first positioning groove 4131. Then, the first ejecting drive 422 drives the first ejector pin 421 to move, and pushes the steel handle in the first positioning groove 4131 to the welding position. At this time, the steel handle will contact the semi-finished medical dental tool. As the steel handle moves, the semi-finished medical dental tool is pushed out by the steel handle and falls into the receiver 81.

[0109] An automatic welding device and a welding method provided by an embodiment of the present invention can realize automatic loading and automatic welding of steel handles and alloy materials, thereby effectively improving production efficiency. When welding steel handles or alloy materials of different lengths, it is only necessary to adjust the distance that the first ejector pin 421 moves toward the steel handle to push the steel handles of different lengths to the welding position, or it is only necessary to adjust the distance that the second ejector pin 721 moves toward the alloy material to make the welding end face of the alloy material abut against the welding end face of the steel handle. The entire adjustment process is simple, rapid, and easy to use. At the same time, according to the structure of the automatic welding device, when the automatic welding device is used for welding, the air between the welding end faces of the steel handle and the alloy material can be discharged, thereby ensuring the welding quality of the steel handle and the alloy material.
