[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0035] Reference Figure 1 and Figure 2As shown, an ultrasonic knife assembly method of the present invention includes the following steps: S1: the carrier 21 for accommodating accessories is moved to the first position, and the first shell 221, the second shell 231, the knife rod and the trigger assembly 241 are placed in the multiple positioning grooves of the carrier 21; S2: the carrier 21 is moved to the second position, and a lubricating layer is automatically applied to the first shell 221 and the second shell 231, and the trigger assembly 241 is automatically assembled with fasteners; S3: the carrier 21 is moved to the third position, and the elastic component is assembled with the sleeve, and the assembled sleeve is placed in the positioning groove on the carrier 21, and the power touch control and button are simultaneously assembled. Assembled on the first shell 221; S4: the carrier 21 moves to the fourth position, automatically scans the code on the knife rod, and screws the knife rod into the assembled sleeve; S5: the carrier 21 moves to the fifth position, assembles the trigger assembly 241 with the first shell 221, assembles the knob with the sleeve, assembles the conductive part with the knob, and assembles the knife rod with the first shell 221; S6: the carrier 21 moves to the sixth position, assembles the spring with the first shell 221, assembles the second shell 231 with the first shell 221, and presses the second shell 231 and the first shell 221.

[0036] An ultrasonic knife assembly method of the present embodiment simultaneously completes the coating of a lubricating layer on the first shell 221 and the second shell 231 and the assembly of fasteners on the trigger assembly 241, and also simultaneously completes the assembly of the elastic component and the sleeve and the assembly of the power touch control and the button on the first shell 221, so that steps that do not affect each other during assembly can be performed simultaneously, thereby shortening the overall assembly time and improving assembly efficiency. The movement of the carrier 21 can automatically complete the scanning of the knife rod and can be pressed on the carrier 21, thereby avoiding the steps of moving the knife rod to scan the code and the steps of assembling and fixing the first shell 221 and the second shell 231 with the pressing tool in the prior art, thereby further shortening the overall assembly time and improving assembly efficiency.

[0037] The main part of the ultrasonic scalpel includes a handle, a blade rod, a sleeve and a trigger assembly 241. The handle is composed of a first shell 221 and a second shell 231. The trigger assembly 241 includes multiple parts connected by pins. The trigger assembly 241 is connected to the handle. A power touch module is installed in the handle, and a button for triggering the power touch module is connected to the shell, so that the power of the ultrasonic scalpel can be adjusted during operation through the button. An elastic component and a knob are installed on the sleeve, and a pin needle is provided on the knob. Part of the blade rod is located in the sleeve, and the sleeve is connected to the handle, so that the ultrasonic scalpel can be used through the knob and the trigger assembly 241. The structure of the ultrasonic scalpel is existing technology.

[0038] Reference Figure 3 and Figure 4As shown, the carrier 21 is flat as a whole, and includes a plurality of positioning grooves for accommodating accessories of the ultrasonic knife main body. Specifically, the plurality of positioning grooves include a first positioning groove 22, a second positioning groove 23, a third positioning groove 24, a fourth positioning groove 25 and a fifth positioning groove 26, wherein the first positioning groove 22 is used to clamp with the first shell 221, the second positioning groove 23 is used to clamp with the second shell 231, the third positioning groove 24 is used to clamp with the trigger assembly 241, the fourth positioning groove 25 is used to clamp with the knife rod, and the fifth positioning groove 26 is used to clamp with the sleeve, wherein the first positioning groove 22 and the third positioning groove 24 are respectively located on the edges of opposite sides of the carrier 21, the second positioning groove 23 is located close to the first positioning groove 22, and the second positioning groove 23 and the third positioning groove 24 are a certain distance apart, so as to facilitate the simultaneous coating of the lubricating layer on the first shell 221 and the second shell 231 and the assembly of the fasteners of the trigger assembly 241 in step S2. The carrier 21 is also provided with a sixth positioning groove 27, which is connected to the first positioning groove 22. After the knife bar is assembled with the first housing 221, the sixth positioning groove 27 is used to accommodate the knife bar. The provision of the carrier 21 facilitates rapid processing of accessories and prevents damage to the accessories during movement.

[0039] Reference Figure 5 As shown, the carrier 21 is moved by the conveyor 1, and the conveyor 1 can be regarded as a belt conveyor mechanism. Specifically, the first position, the second position, the third position, the fourth position, the fifth position and the sixth position are located in sequence on the conveying path of the conveyor 1. The conveyor 1 is a double-layer belt conveyor mechanism, and the two layers of conveying paths are located at different heights and the conveying paths are parallel. A lifting mechanism 11 is provided at both ends of the conveyor 1, and a lifting platform 12 is provided in the lifting mechanism 11. A transition piece is provided on the lifting platform 12, and the transition piece can also be regarded as a belt conveyor mechanism. Through the movement of the lifting platform 12, the transition piece can be parallel to the two layers of conveying paths of the conveyor 1, so that the carrier 21 can be moved to the lifting platform 12, and the movement of the lifting platform 12 enables the carrier 21 to move to different conveying paths. In this embodiment, the upper conveying path of the conveyor 1 is used for the assembly of the main part of the ultrasonic knife, and the lower conveying path of the conveyor 1 is used for the storage, loading and unloading of the carrier 21.

[0040] Reference Figure 6As shown, the conveying member 1 is also provided with a plurality of movable plates 13, which are located on the conveyor belt, so that the conveying member 1 can drive the movable plates 13 to move. The carrier 21 is placed on the movable plates 13, so that the carrier 21 can be driven to move by the movable plates 13. The conveying member 1 is provided with a limiter 14, a blocking member 15, a second driving member and a top plate 17 corresponding to the first position, the second position, the third position, the fourth position, the fifth position and the sixth position. The second driving member can be regarded as a linear driving member. The limiter 14, the blocking member 15 and the second driving member are all connected to the conveying member 1. The blocking member 15 can be regarded as a blocking cylinder. The blocking end of the blocking member 15 can extend into the conveying path of the conveying member 1. The movable plate 13 is provided with an opening. The blocking end of the blocking member 15 can abut against the side wall of the opening, so that the movable plate 13 stays in the corresponding assembly position, that is, the movable plate 13 can be positioned by the blocking member 15. The top plate 17 is connected to the output end of the second driving member, and the second driving member drives the top plate 17 to rise, so that the top plate 17 can abut against the bottom side of the movable plate 13 and drive the movable plate 13 to rise, thereby driving the carrier 21 to rise. The side wall of the conveying member 1 is connected to multiple limit members 14, and the limit members 14 include limit ends extending toward the moving path of the top plate 17. The top plate 17 can drive the carrier 21 to abut against the limit ends of the limit members 14, thereby fixing the carrier 21. The conveying member 1 is also connected to a sensor 16, which is connected to the controller. The detection end of the sensor 16 faces the moving path of the movable plate 13. The sensor 16 can detect whether the movable plate 13 passes through the assembly position. When the movable plate 13 passes, the blocking end of the blocking member 15 extends and blocks the movable plate 13 from continuing to move.

[0041] The conveying member 1 is also connected to a stop member, which includes a movable block 18 and a mounting seat 19. The movable block 18 is hinged to the mounting seat 19, and a spring is provided in the mounting seat 19. The spring is in contact with the movable block 18. The movable block 18 includes a guide surface. The plane where the guide surface is located is at an obtuse angle to the conveying path of the conveying member 1, and the guide surface is toward the input end of the conveying path, so that the movable plate 13 can press down the movable block 18 after it is in contact with the guide surface of the movable block 18 during movement. At this time, the spring is compressed. When the movable plate 13 is in contact with the blocking member 15, the movable plate 13 no longer presses down the movable block 18. At this time, the spring drives the movable block 18 to reset. When the movable plate 13 moves in the opposite direction after being in contact with the blocking member 15, it can be in contact with the movable block 18, so that the movable block 18 can prevent the movable plate 13 from moving in the opposite direction after being in contact with the blocking member 15. Preferably, at least two positioning pins are provided on the top plate 17, and the top ends of the positioning pins are conical. Positioning holes corresponding to the positioning pins are provided on the movable plate 13. After the top plate 17 rises, the positioning pins are engaged with the positioning holes, thereby positioning the movable plate 13. The carrier 21 and the movable plate 13 can also be positioned by the cooperation of the positioning pins and the positioning holes, so that the positioning accuracy of the carrier 21 in the assembly position is higher.

[0042] Reference Figure 7 As shown, step S1 includes: moving the carrier 21 for accommodating accessories to the first position, placing the first shell 221, the second shell 231, the knife bar and the trigger assembly 241 in multiple positioning grooves of the carrier 21. Specifically, step S1 is used to load the accessories, and the loading of the accessories is completed at the loading station 2. A accommodating box 28 for accommodating the trigger assembly 241 is provided above the first position, and a plurality of first storage trays 29 for accommodating the knife bar, the first shell 221 and the second shell 231 are also provided on one side of the first position. After the carrier 21 moves to the first position through the conveying member 1, the first shell 221 is placed in the first positioning groove 22, the second shell 231 is placed in the second positioning groove 23, the trigger assembly 241 is placed in the third positioning groove 24, and the knife bar is placed in the fourth positioning groove 25, thereby completing the loading of the carrier 21.

[0043] Reference Figures 8 to 10 As shown, step S2 includes: the carrier 21 moves to the second position, automatically applies a lubricating layer to the first shell 221 and the second shell 231, and simultaneously automatically assembles fasteners to the trigger assembly 241. Specifically, the fasteners can be considered pins. After the carrier 21 is moved to the second position and positioned by the conveyor 1, the coating assembly 3 applies a lubricating layer to the first shell 221 and the second shell 231, and the fasteners are assembled to the trigger assembly 241 by the assembly assembly 4. Both the coating assembly 3 and the assembly assembly 4 are connected to a mounting plate, which is fixed to the exterior.

[0044] The coating assembly 3 includes a first drive module 31, a first drive member 32, and a coating member 33. The coating member 33 can be considered a grease extrusion mechanism. The first drive module 31 can be considered a three-axis movement module. The output end of the first drive module 31 is connected to a first connecting plate 34, and the first drive member 32 is connected to the output end of the first drive module 31 via the first connecting plate 34. The first drive member 32 is a linear drive member, and the output end of the first drive member 32 is connected to the coating member 33. Through the cooperation of the first drive module 31 and the first drive member 32, the coating member 33 can move toward the position of the first shell 221 and the second shell 231 in the second position. After the coating end of the coating member 33 reaches the coating position of the first shell 221 and the second shell 231, it begins to apply the lubricating layer.

[0045] The assembly component 4 includes a second drive module 41 and an assembly part 44. The assembly part 44 can be regarded as an automatic pinning mechanism, and the assembly part 44 can complete the automatic feeding and assembly of fasteners. The second drive module 41 can be regarded as a three-axis moving module. The output end of the second drive module 41 is connected to the second connecting plate 43. The assembly part 44 is connected to the second connecting plate 43. The second drive module 41 drives the assembly part 44 to move toward the trigger assembly 241 located in the second position, so that the assembly part 44 can press the fastener into the trigger assembly 241. The second connecting plate 43 is also connected to a detection part 45. The detection part 45 is connected to the controller. The detection part 45 can be regarded as a visual detection system. The detection end of the detection part 45 is facing the second position. The detection part 45 can locate the position of the assembly hole on the trigger assembly 241 for pressing the fastener, so that the assembly part 44 can accurately press the fastener into the assembly hole. Assembly assembly 4 also includes a dip box 42 containing lubricating oil. Assembly member 44 is dipped in lubricating oil before being assembled with fasteners to prevent jamming when assembly member 44 is pressed into the fasteners. The arrangement of coating assembly 3 and assembly assembly 4 allows for simultaneous application of a lubricating layer to first housing 221 and second housing 231 and assembly of fasteners to trigger assembly 241, thereby improving assembly efficiency.

[0046] Reference Figures 11 to 14As shown, step S3 includes: moving the carrier 21 to the third position, assembling the elastic component and the sleeve, placing the assembled sleeve in the positioning groove on the carrier 21, and assembling the power touch component and the button on the first shell 221. Specifically, the assembly of the elastic component and the sleeve is completed at the first assembly station 5, the power touch component and the button are assembled on the first shell 221 and completed at the second assembly station 6, and the elastic component is assembled with the sleeve through a press-fitting assembly. The press-fitting assembly includes a fourth drive member 53, a fifth drive member 55, a sixth drive member 56 and a press-fitting frame 54. The fourth drive member 53 and the fifth drive member 55 are both linear drive members, and the sixth drive member 56 is a rotary drive member. The output end of the fourth drive member 53 is connected to the press-fitting frame 54, and the sixth drive member 56 is connected to the output end of the fifth drive member 55 through the connecting frame. The fifth drive member 55 can drive the sixth drive member 56 to rise and fall, and the fourth drive member 53 can drive the press-fitting frame 54 to move toward the direction close to the fifth drive member 55. The output end of the sixth drive member 56 is connected to the press-fitting part, and through the cooperation of the fifth drive member 55 and the sixth drive member 56, the press-fitting part can assemble the elastic component and the sleeve. The press-fitting frame 54 is provided with a press-fitting groove 57, with a through-hole 58 at its bottom. This groove is used to accommodate the elastic component, allowing the sleeve to pass through both the groove and the through-hole. The frame 54 also has a clearance opening at its bottom, allowing the sleeve to pass through, thus preventing the sleeve from being too long and preventing assembly. The frame 54 also has a cutting groove 59 that communicates with the press-fitting groove 57, facilitating adjustment of the elastic component's position within the groove. In this embodiment, the elastic assembly includes a female spring seat, three wave springs, a snap ring, and a male spring seat. The female spring seat, two short wave springs, the snap ring, the long wave spring, and the male spring seat are sequentially placed into the press-fitting groove 57. The sleeve is then passed through the elastic assembly and the through hole 58, so that the claws of the male spring seat engage with the grooves on the sleeve. Finally, the fourth driving member 53 drives the press-fitting frame 54 to move to the press-fitting position. The fifth driving member 55 and the sixth driving member 56 cooperate to enable the press-fitting portion to engage with the sleeve and drive the sleeve to rotate, thereby assembling the elastic assembly and the sleeve. The press-fitting groove 57 of different shapes and sizes can be provided depending on the elastic assembly. When the elastic assembly and the sleeve need to be assembled by stamping, the sixth driving member 56 is a linear driving member, so that the press-fitting portion abuts against the end of the sleeve to achieve assembly of the elastic assembly and the sleeve.

[0047] Step S3 also includes a storage step. When the carrier 21 has not yet moved to the third position, after the elastic component and the sleeve are assembled, the assembled sleeve is placed on the pre-assembly frame 52. The pre-assembly frame 52 also has a press-fitting groove 57 and a through-hole 58 with the same structure as the press-fitting frame 54. Therefore, after the elastic component and the sleeve are assembled, the sleeve can be inserted through the through-hole 58, and the elastic component is positioned in the press-fitting groove 57, so that the overall position of the elastic component and the sleeve is fixed. When the carrier 21 moves to the third position, the sleeve assembled with the elastic component on the pre-assembly frame 52 can be placed in the fifth positioning groove 26, thereby improving the consistency of the assembly of the elastic component and the sleeve and enhancing assembly efficiency. One side of the pre-installed frame 52 is provided with a second storage tray 51 for accommodating the sleeve and a plurality of storage boxes for accommodating elastic component accessories. The side of the conveying part 1 away from the press-fitting component is provided with a third storage tray 61 for accommodating the power touch component and a fourth storage tray 62 for accommodating the button, that is, the assembly position of the elastic component and the sleeve and the assembly position of the power touch component, the button and the first shell 221 are located on both sides of the conveying part 1, so as to avoid mutual influence during assembly.

[0048] In this embodiment, the power touch control component can be regarded as a power touch control module, and the buttons include a button with three bumps and a button without bumps. During specific assembly, the power touch control component is first snapped into the corresponding groove in the first shell 221, and then the cables are arranged in order into the wire groove of the first shell 221. The electrode ring is installed in the corresponding groove, and the mounting hole at the bottom of the button with three bumps is snapped into the corresponding positioning column on the outside of the first shell 221. The mounting hole at the bottom of the button without bumps is snapped into the corresponding positioning column on the outside of the first shell 221, thereby realizing the assembly of the power touch control component and the button with the first shell 221. After assembly is completed, the sleeve is placed in the fifth positioning groove 26 of the carrier 21. Different assembly methods can be adopted according to different power touch control components, buttons and first shell 221. By assembling the elastic component with the sleeve and assembling the power touch control component and button with the first shell 221, assembly efficiency is improved.

[0049] Reference Figure 15As shown, step S4 includes: the carrier 21 moves to the fourth position, automatically scans the code on the tool rod, and screws the tool rod into the assembled sleeve at the same time. Specifically, step S4 is completed at the third assembly station 7, and the tool rod is scanned by the code scanning component 72. The code scanning component 72 is connected to the controller, and the code scanning component 72 is connected to the side wall of the conveying member 1. The code scanning end of the code scanning component 72 is located above the conveying path of the conveying member 1 and faces the tool rod located at the fourth position. When the carrier 21 is positioned at the fourth position, the code scanning component 72 can automatically scan the tool rod on the carrier 21. In another embodiment, the code scanning component 72 can also be located below the conveying path of the conveying member 1. A code scanning hole is provided on the carrier 21. At this time, the code scanning position on the tool rod corresponds to the code scanning hole. The code scanning end of the code scanning component 72 faces the code scanning hole, thereby realizing automatic code scanning. The code scanning component 72 is located below the conveying path of the conveying member 1, which can avoid the limitation of the movement range during the assembly of the tool rod. By automatically scanning the code, the tool bar does not need to be moved for scanning, thus improving the assembly efficiency.

[0050] In this embodiment, when assembling the tool bar, the tool bar is rotated from the end of the sleeve into the sleeve, with part of the tool bar positioned outside the sleeve. Grease is then applied to the end of the tool bar. Finally, the tool bar is rotated and inserted into the sleeve until the tool bar and the sleeve end abut against each other. The assembled sleeve and tool bar are then placed in the fifth positioning slot 26 of the carrier 21. Different assembly methods can be used depending on the tool bar and sleeve. A fifth storage tray 71 for grease and grease application tools is provided on one side of the fourth position.

[0051] Reference Figure 16 As shown, step S5 includes: moving the carrier 21 to the fifth position, assembling the trigger assembly 241 with the first housing 221 , assembling the knob with the sleeve, assembling the conductive member with the knob, and assembling the assembled sleeve with the first housing 221 . Specifically, step S5 is completed at the fourth assembly station 8. The conductive member can be considered a pin. In this embodiment, when assembling the above-mentioned accessories, the trigger assembly 241 is first engaged with the corresponding position of the first housing 221. At this time, the portion of the trigger assembly 241 protruding from the first housing 221 is located in the avoidance groove on the carrier 21. The knob is then installed from the end of the sleeve and moved to a position where the mounting hole of the knob corresponds to the mounting hole of the sleeve. The conductive member is inserted into the mounting hole of the knob. A limiting post is then inserted into the mounting hole of the knob. The limiting post can be considered a pin. Finally, the sleeve is assembled with the first housing 221. A spring is taken and engaged with the corresponding groove on the first housing 221. This completes the assembly of the trigger assembly 241, the knob, the conductive member, the sleeve, and the first housing 221. After assembly, the sleeve is located in the sixth positioning groove 27. Different assembly methods can be adopted depending on the different trigger assemblies 241, knobs, conductive members, sleeves, and first housings 221. A sixth storage tray 81 for accommodating knobs and conductive parts is provided on one side of the fifth position.

[0052] Step S6 includes moving the carrier 21 to the sixth position, assembling the spring with the first housing 221, assembling the second housing 231 with the first housing 221, and pressing the second housing 231 and first housing 221 together. Specifically, the spring can be considered a compression spring. In this embodiment, when assembling the spring, the trigger assembly 241 is pressed down, the spring is assembled with the raised portion of the first housing 221, and the spring is pressed down until the spring engages with the corresponding slot on the first housing 221. Finally, the trigger assembly 241 is released to complete the spring assembly. Different assembly methods can be used depending on the different springs, trigger assemblies 241, and first housing 221.

[0053] In this embodiment, the second shell 231 and the first shell 221 are pressed together by a pressing assembly 9. The pressing assembly 9 includes a third driving member 92 and a pressure plate 93. The third driving member 92 is fixed to the outside through a support frame 91. The third driving member 92 is a linear driving member. The conveying path of the conveying member 1 passes through the pressing space of the support frame 91. The pressure plate 93 is connected to the output end of the third driving member 92. The pressure plate 93 is located in the pressing space and can move toward or away from the sixth position. When the carrier 21 moves to the sixth position and is positioned, the spring is first assembled with the first shell 221, and then the open side of the second shell 231 is aligned with the open side of the first shell 221, so that the second shell 231 and the first shell 221 form a handle. Finally, the third driving member 92 drives the pressure plate 93 to move, so that the pressure plate 93 presses the second shell 231 and the first shell 221 together. The first shell 221 and the second shell 231 on the carrier 21 are pressed together by the pressing plate 93 , thereby avoiding the need to remove the second shell 231 and the first shell 221 and then fix them with a pressing tool, thereby improving assembly efficiency.

[0054] After step S6, an airtightness detection step is also included, in which the assembled ultrasonic knife assembly is taken out from the carrier 21, and the airtightness detection of the ultrasonic knife assembly is performed through the airtightness detection mechanism 94. The airtightness detection mechanism 94 is a prior art.

[0055] In this embodiment, each step takes about 25 seconds to complete, thereby avoiding a decrease in overall assembly efficiency due to a single step taking too long.

[0056] An ultrasonic knife assembly method of the present invention simultaneously completes the coating of a lubricating layer on the first shell 221 and the second shell 231 and the assembly of fasteners on the trigger assembly 241, and also simultaneously completes the assembly of the elastic component and the sleeve and the assembly of the power touch component and the button on the first shell 221, so that steps that do not affect each other during assembly can be performed simultaneously, thereby shortening the overall assembly time and improving assembly efficiency. The movement of the carrier 21 can automatically complete the scanning of the knife rod and can be pressed on the carrier 21, thereby avoiding the steps of moving the knife rod to scan the code and the steps of assembling and fixing the first shell 221 and the second shell 231 with the pressing tooling in the prior art, thereby further shortening the overall assembly time and improving assembly efficiency.

[0057] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
