Detailed implementation manners

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figure 1-16 As shown, a fully insulated disconnector according to an embodiment of the present invention includes an insulating housing 1. The insulating housing 1 has a trough-shaped structure and internally houses a blade assembly 100. At both ends of the bottom of the trough of the insulating housing 1, there are respectively a first connecting member 101 for installing a terminal and a second connecting member 102 for installing a clamping spring. A hinge member 103 is movably arranged on one of the first connecting members 101, and the other end of the hinge member 103 is fixedly connected to the blade assembly 100. The blade assembly 100 includes an insulating bottom plate body 104, and two blade plates 105 are respectively arranged at the front and rear ends of the top surface of the insulating bottom plate body 104. A fuse piece body 106 is connected between every two front and rear corresponding blade plates 105. The fuse piece body 106 is detachably connected to the blade plate 105 through a clamping component.

[0039] The clamping component includes a through hole 107 opened on the blade plate 105. A spring piece 108 is arranged inside the through hole 107. One end of the spring piece 108 is fixedly connected to the inner end surface of the through hole 107 and has a bent section 109 extending outside the through hole 107. The fuse piece body 106 includes an arc section 110 in the middle section and connecting sections 112 at both ends. Clamping openings 113 adapted to the spring piece 108 are respectively opened on the connecting sections 112.

[0040] During use, the first connecting member 101 and the second connecting member 102 are both pre-embedded in the insulating housing 1. The first connecting member 101 is installed with a terminal, and the second connecting member 102 is installed with a clamping spring. One end of the blade assembly 100 is connected to the hinge member 103 to realize the hinge with one of the first connecting members 101 and conduct electricity with the terminal. When the blade assembly 100 is in the closing state, its hinged end is conducted with one of the first connecting members 101 and the movable end is conducted with the other first connecting member 101, thereby realizing the conduction of the two terminals. When the blade assembly 100 is in the closing state, the two clamping springs clamp the blade plates 105 to further limit the blade assembly 100 and ensure the stability of the blade assembly 100 in the closing state.

[0041] The fuse piece is detachably connected to the knife plate 105 through a clamping assembly, which facilitates the daily maintenance, loading and unloading of the fuse piece. Specifically, when installing the fuse piece, align the clamping openings 113 at both ends of the fuse piece with the two through openings 107 on the knife plate 105, and then push the fuse piece along the knife plate 105. During the pushing process of the fuse piece, the bending section 109 is forced to bend outward and deform. At this time, continue to push the fuse piece until the clamping openings 113 at both ends of the fuse piece reach the corresponding positions of the bending section 109 of the elastic piece 108. At this time, the elastic piece 108 rebounds to its initial position due to its own elastic reciprocating force and makes the bending section 109 and the clamping opening 113 form a clamping, completing the installation of the fuse piece. When it is necessary to disassemble the fuse piece, the reverse operation can be performed.

[0042] The steps of a production process for manufacturing a fully insulated disconnector are as follows: S1. Material selection: Select a suitable fuse piece blank; S2. Blanking: Feed the fuse piece blank into a blanking and punching device to obtain a fuse piece body; S3. Punching and bending: Feed the fuse piece body into a full-automatic punching and bending machine to punch the clamping openings 113 and bend the bending section 109; S4. Grinding: Clean the burrs at the blanking and punching parts of the fuse piece body through a grinding device; S5. Assembly: Feed the fuse piece body obtained in step S4 and the knife plate 105 into a full-automatic assembly machine to assemble and obtain a knife body assembly 100; S6. Fitting: Install the knife body assembly 100 obtained in step S5 into the insulating housing 1 to obtain a fully insulated disconnector.

[0043] During use, the full-automatic punching and bending machine realizes automatic punching and bending of the fuse piece body, and the full-automatic assembly machine automatically assembles the fuse piece body and the knife body assembly 100, effectively improving the production efficiency of the fully insulated disconnector and reducing the production cost at the same time.

[0044] The full-automatic punching and bending machine includes a machine frame 2. A conveyor belt 200 is arranged inside the machine frame 2 and is driven from right to left. On the left and right sides of the top of the machine frame 2, a first track frame 201 and a second track frame 202 are respectively arranged. A feeding mechanism 203 is installed on the first track frame 201 and a discharging mechanism 204 is arranged on the second track frame 202. The structures and working principles of the feeding mechanism 203 and the discharging mechanism 204 are the same. At the top of the machine frame 2, between the first track frame 201 and the second track frame 202 and corresponding to the conveyor belt 200, two punching units 3 and two bending units 300 are arranged in sequence. A number of material placing seats 301 are equidistantly and spacedly distributed on the conveyor belt 200. The conveyor belt 200 works and drives each material placing seat 301 to pass through the discharging mechanism 204, the punching unit 3, the bending unit 300 and the discharging unit in sequence.

[0045] During use, a number of material placement seats 301 are evenly and spacedly distributed on the conveyor belt 200. The conveyor belt 200 is conveyed from left to right and drives each material placement seat 301 to pass through the first track frame 201, the punching unit 3, the bending unit 300, and the second track frame 202 in sequence. When the material placement seat 301 passes through the first track frame 201, the feeding mechanism 203 feeds the molten sheet body onto the material placement seat 301. When the material placement seat 301 passes through the punching unit 3, the punching unit 3 punches it to obtain a clamping through hole. When the material placement seat 301 passes through the bending unit 300, the bending unit 300 performs bending processing on it to obtain a bent section 109. Then, the material placement seat 301 reaches the second track frame 202, and the discharging mechanism 204 of the second track frame 202 discharges and collects the processed molten sheet on the material placement seat 301.

[0046] The loading mechanism 203 or the unloading mechanism 204 includes a transverse sliding rail 205 fixedly arranged on the first track frame 201 or the second track frame 202, a vertical sliding rail 206 slidably arranged on the transverse sliding rail 205, a sliding die base 207 slidably arranged on the vertical sliding rail 206, and a feeding frame 208 drivingly connected to the sliding die base 207. Four feeding frames 208 are provided and are pairwise opposite mechanical grippers 209; the machine frame 2 is located on both sides of the first track frame 201 and two loading conveying units 210 are arranged at positions corresponding to the mechanical grippers 209. The loading conveying unit 210 includes a loading bottom plate 211, and the loading bottom plate 211 is fixedly connected to the machine frame 2 through a mounting frame 212. Two loading conveyor belts 213 are correspondingly wound around the outer surface of the loading bottom plate 211. Two first baffles 214 are correspondingly arranged on the upper surface of the loading bottom plate 211 at positions corresponding to the two loading conveyor belts 213. A conveying interval adapted to the melt sheet body is formed between the two first baffles 214. Clamping openings 215 are formed at positions corresponding to the mechanical grippers 209 on both of the two first baffles 214. A material blocking member 216 is further arranged between the two first baffles 214. The material blocking member 216 blocks the melt sheet body so that the melt sheet bodies are arranged in sequence on the loading bottom plate 211; the machine frame 2 is located on both sides of the second track frame 202 and two unloading conveying units 217 are arranged at positions corresponding to the mechanical grippers 209. The unloading conveying unit 217 includes an unloading bottom plate 218, and the unloading bottom plate 218 is fixedly connected to the machine frame 2 through a mounting frame 212. Two unloading conveyor belts 219 are correspondingly wound around the outer surface of the unloading bottom plate 218. Two second baffles 220 are correspondingly arranged on the upper surface of the unloading bottom plate 218 at positions corresponding to the two unloading conveyor belts 219. A conveying interval adapted to the melt sheet body is formed between the two second baffles 220. A placement concave position 221 adapted to the bending section 109 of the melt sheet body is further formed in the middle of the unloading bottom plate 218; two supporting guide bars 222 are correspondingly arranged at the left end of the unloading bottom plate 218. Two limiting guide bars 223 are arranged above both of the two supporting guide bars 222 on the unloading bottom plate 218. A guiding interval adapted to the melt sheet body is formed between the limiting guide bars 223 and the supporting guide bars 222. Two positioning guide bars 224 adapted to the bending section 109 of the melt sheet body are further arranged at the lower end of the unloading bottom plate 218. The ends of the supporting guide bars 222, the limiting guide bars 223 and the positioning guide bars 224 all incline downward. Material collecting boxes 225 are arranged at positions corresponding to the unloading conveying units 217 on both sides of the machine frame 2.

[0047] During use, when working, the staff sequentially place the melt sheet bodies to be processed at the right ends of the respective loading bottom plates 211. Two loading conveyor belts 213 are correspondingly wound around the outside of the loading bottom plate 211. The upper surfaces of the two loading conveyor belts 213 are both higher than the upper surface of the loading bottom plate 211. The conveyor belts drive the melt sheet bodies to move along the loading bottom plate 211 from left to right. Two first baffles 214 are correspondingly arranged on the top surface of the loading bottom plate 211. A conveying interval adapted to the melt sheet body is formed between the two first baffles 214 to define the conveying path of each melt sheet body;

[0048] At the corresponding positions of the two first baffles 214 where the mechanical gripper 209 is located, there are material clamping openings 215, so as to facilitate the mechanical gripper 209 to pick up the fused sheet body above the loading bottom plate 211. A material blocking member 216 is also arranged between the two first baffles 214. The material blocking member 216 blocks the fused sheet body so that the fused sheet bodies are arranged in sequence on the loading bottom plate 211. After the mechanical gripper 209 picks up the fused sheet body corresponding to each material clamping opening 215, the conveyor belt 200 operates to drive the subsequent fused sheet bodies to move and supplement the fused sheet bodies missing at the material clamping openings 215, so that there are always fused sheet bodies at the material clamping openings 215 to ensure the smoothness of loading;

[0049] During loading, the vertical slide rail 206 is controlled to slide along the transverse slide rail 205 to drive the feeding frame 208 to move. The movement of the feeding frame 208 causes two of the mechanical grippers 209 to move to the loading conveying unit 210 on one side. At this time, the sliding die base 207 moves up and down along the vertical slide rail 206 and cooperates with the mechanical gripper 209 to pick up the fused sheet body of the loading conveying unit 210. After the sliding die base 207 returns to its original position, the vertical slide rail 206 is controlled to move along the transverse slide rail 205. At this time, the feeding frame 208 drives the two mechanical grippers 209 to place the fused sheet body into the material placing seat 301 above the conveyor belt. At the same time, the other two mechanical grippers 209 pick up the fused sheet body of the loading unit on the other side;

[0050] Through the transverse slide rail 205, the vertical slide rail 206, the sliding die base 207, the feeding frame 208 and the four pairwise corresponding mechanical grippers 209, the feeding frame 208 is controlled to intermittently change positions left and right. The four mechanical grippers 209 cooperate with the loading conveying units 210 on both sides to realize the efficient loading of the fused sheet body. The intermittent movement of the conveyor belt causes the material placing seat 301 to pass through the first track frame 201 in sequence and stay briefly to cooperate with the loading action of the mechanical gripper 209;

[0051] The intermittent movement of the conveyor belt 200 causes the material placement seat 301 to pass through the first track frame 201, the punching unit 3, and the bending unit 300, and then reach the second track frame 202. The working principle and structure of the blanking mechanism 204 are the same as those of the feeding mechanism 203. Thus, the melted sheets processed by the punching unit 3 and the bending unit 300 on each material placement seat 301 are blanked to the blanking conveyor units 217 on both sides. The mechanical gripper 209 places the melted sheet above the blanking bottom plate 218. The blanking bottom plate 218 is provided with a placement interval adapted to the bending section 109 of the melted sheet body. The blanking conveyor belt 219 drives the melted sheet to be transmitted from right to left and enters the guiding interval formed between the two second baffles 220. The blanking conveyor belt 219 drives the transmission of the melted sheet and the guiding interval limits the transmission path. The melted sheet moves from left to right along the blanking conveyor belt 200 and falls from the left end of the blanking bottom plate 218. A guiding interval for guiding the melted sheet to be blanked along a predetermined trajectory is formed between the supporting guide bar 222, the limiting guide bar 223, and the positioning guide bar 224. Receiving boxes 225 are arranged on both sides of the frame 2 to receive and collect the melted sheets falling from the blanking bottom plate 218.

[0052] The material placement seat 301 includes a seat body 302 fixedly connected to the conveyor belt 200. A processing recess 303 adapted to the melted sheet body is provided on the top surface of the seat body 302. An extending interval 304 for the mechanical gripper 209 to extend into is extended in the middle of the processing recess 303.

[0053] During use, both ends of the seat body 302 have connecting parts. The connecting parts are fixedly connected to the conveyor belt 200 through fasteners. A processing recess 303 adapted to the melted sheet body is provided on the top surface of the seat body 302. The edge of the upper opening end of the processing recess 303 has a guiding inclined waist to ensure that the melted sheet body can quickly and accurately fall into the processing recess 303. Two extending intervals 304 are provided at the position corresponding to the bending section 109 of the melted sheet in the processing recess 303. The extending intervals 304 are used for the manipulator to insert and clamp the melted sheet.

[0054] The punching unit 3 includes a first support frame 305 and a first power source 306 fixedly arranged on the top of the first support frame 305. The driving shaft of the first power source 306 extends through and reaches into the first support frame 305 and is connected with a punching substrate 307. The lower end of the punching substrate 307 is fixedly connected with a punching main board 308 through a connecting column. Two punch heads 309 are correspondingly arranged at the bottom of the punching main board 308. A first pre-pressing plate 310 is installed below the punching main board 308, and a punching cooperation hole 311 is provided at the position corresponding to the two punch heads 309 on the first pre-pressing plate 310. A first sliding rod 312 is fixedly arranged at the center of the top of the first pre-pressing plate 310. The first sliding rod 312 is in sliding cooperation with the punching main board 308 and has a limiting part at the top end. A first spring 313 is sleeved outside the first sliding rod 312;

[0055] The bending unit 300 includes a second support frame 314 and a second power source 315 fixedly arranged at the top of the second support frame 314. The drive shaft of the second power source 315 extends through and into the second support frame 314 and is connected to a bending base plate 316. The lower end of the bending base plate 316 is drivingly connected to a bending main plate 317 through a connecting column. A bending head 318 is fixedly installed at the center of the bottom of the bending main plate 317. A second pre-pressing plate 319 is installed below the bending main plate 317, and a bending cooperation hole is provided at the position corresponding to the bending head 318 on the second pre-pressing plate 319. Two second sliding rods 320 are correspondingly arranged at the top of the second pre-pressing plate 319. Each second sliding rod 320 is in sliding fit with the bending main plate 317 and has a limiting portion at the top. A second spring 321 is sleeved outside the second sliding rod 320;

[0056] Support bottom plates 322 are fixedly installed on the inner sides of the first support frame 305 and the second support frame 314, and the support bottom plates 322 are used to provide support for the material placement seat 301.

[0057] During use, the conveyor belt 200 controls the material placement seat 301 to pass through the punching unit 3 and the bending unit 300;

[0058] When the material placement seat 301 reaches the punching unit 3, the drive shaft of the first power source 306 controls the punching substrate 307 to move downward. The punching substrate 307 drives the punching main board 308 to move downward. The downward movement of the punching main board 308 causes its two punches 309 to synchronously contact the fuse sheet body and complete the punching operation of the two clamping openings 113. Among them, the material placement seat 301 has a reserved hole position at the punching positions of the two clamping through holes. The size of the reserved hole position is larger than the size of the punch 309 for the punch 309 to extend into it during punching. During punching, the punch 309 pushes the waste material generated by punching into the reserved hole position to ensure that the punching waste is fully separated from the fuse sheet body. When the punch 309 retracts, the punching waste remains in the reserved hole. Then, the material placement seat 301 drives the fuse sheet body to pass through the bending unit 300 and the blanking mechanism 204 in sequence. After passing through the blanking mechanism 204, the conveyor belt controls the material placement seat 301 to continue moving. The conveyor belt 200 causes the upper end surface of the material placement seat 301 to face downward and circulates it to the starting position (at the loading mechanism 203). When the upper end surface of the material placement seat 301 faces downward, the punching waste remaining in the reserved hole drops. In actual use, a waste material collection trough (not shown in the figure) can be placed at the bottom of the frame 2 to collect the dropped punching waste. Further, a first pre-pressing plate 310 is installed below the punching main board 308. The first pre-pressing plate 310 is in sliding fit with the punching main board 308 through the first sliding rod 312 and the limiting part. When the punching main board 308 moves downward, it causes the first pre-pressing plate 310 to contact the fuse sheet body and achieve pre-pressing (the first spring 313 is compressed and in an energy storage state). Then, the punching main board 308 continues to press downward and passes through the punching cooperation hole 311 to perform the punching operation on the fuse sheet body. After punching, the second power source 315 controls the punching main board 308 to reset. The first pre-pressing plate 310 always presses the fuse sheet body before the punch 309 is completely separated from the fuse sheet body. After the punch 309 is separated from the fuse sheet body, the first pre-pressing plate 310 immediately cancels the pressing on the fuse sheet body. By setting the first pre-pressing plate 310, the displacement of the fuse sheet body before or during punching is avoided and it is ensured that the punch 309 is fully separated from the fuse sheet body when it resets.

[0059] When the material placement seat 301 reaches the bending unit 300, the drive shaft of the second power source 315 controls the bending substrate 316 to move downward. The bending substrate 316 drives the bending main board 317 to move downward. The downward movement of the bending main board 317 causes the bending head 318 below it to contact the fuse sheet body and complete the bending process of the bending section 109. The processing recess 303 opened on the top surface of the material placement seat 301 is sufficient to cooperate with the bending action of the bending head 318. A second pre-pressing plate 319 is installed below the bending main board 317. The second pre-pressing plate 319 is in sliding fit with the bending main board 317 through the second sliding rod 320 and the limiting part. The working principle of the second pre-pressing plate 319 is the same as that of the first pre-pressing plate 310 and it is provided with a bending cooperation hole adapted to the bending head 318. The second pre-pressing plate 319 pre-presses the fuse sheet body before the bending head 318 contacts the fuse sheet body.

[0060] Support base plates 322 are fixedly provided on the inner sides of the first support frame 305 and the second support frame 314. The support base plates 322 are used to provide support for the material placement seat 301 to ensure the stability of the material placement seat 301 during the punching or bending process, and to ensure stable force application when the fuse piece body is punched or bent.

[0061] The fully automatic assembly machine includes a base 4. Above the base 4, there are provided two fuse piece body conveying units 400, an insulating base plate conveying unit 401, and a material clamping mechanism 402. The structure and principle of the material clamping mechanism 402 are the same as those of the feeding mechanism 203 and it has three mechanical grippers 209. The fuse piece body conveying unit 400 has the same structural principle as the feeding conveying unit 210; the insulating base plate conveying unit 401 includes a transmission base plate 5. A feeding belt 500 is wound around the transmission base plate 5. Two third baffles 501 are correspondingly provided on both sides of the feeding belt 500 on the top surface of the transmission base plate 5. A feeding interval adapted to the tool plate 105 is formed between the two third baffles 501.

[0062] During use, the staff manually load the fuse piece finished products obtained by processing with the fully automatic punching and bending machine onto the fuse piece body conveying unit 400. The fuse piece body conveying unit 400 has the same structural principle as the feeding conveying unit 210. The fuse piece finished products are arranged above the fuse piece body conveying unit 400 and conveyed from left to right. The staff manually load the tool plate 105 to the insulating base plate conveying unit 401. Two third baffles 501 are correspondingly provided above the transmission base plate 5. A feeding interval adapted to the tool plate 105 is formed between the two third baffles 501. The feeding belt 500 conveys the tool plate 105 and arranges the tool plate 105 neatly above the transmission base plate 5;

[0063] During operation, the three mechanical grippers 209 of the material clamping mechanism 402 each clamp and convey two fuse piece body conveying units 400 and one tool plate 105 each time, and then assemble the two fuse pieces and the tool plate 105 to obtain a tool body assembly 100.

[0064] A first material placement seat 6 is further provided above the base 4 at the left end of the conveyance of the tool plate 105. A placement recess 600 adapted to the tool plate 105 is provided at the top of the first material placement seat 6. A placement cavity 601 is formed inside the first material placement seat 6. A through groove 602 communicating with the placement recess 600 is provided on the top wall inside the placement cavity 601. A top material cylinder 603 is provided inside the placement cavity 601 and the top material cylinder 603 is drivingly connected to a top material plate 604 adapted to the through groove 602;

[0065] A second discharge seat 605 is provided above the base 4 at the left end of the molten sheet conveying unit 400. A mounting recess 606 is provided at the center of the second discharge seat 605. An open end of the mounting recess 606 is extended with a discharge area 607 adapted to the molten sheet. A power cylinder 608 is fixedly installed in the mounting recess 606. The output shaft of the power cylinder 608 is driven and connected to a pneumatic clamp 609 adapted to the molten sheet. The base 4 is located in the middle of the two second discharge seats 605 and an assembly unit 7 is provided at the end away from the first discharge seat 6.

[0066] During use, when the clamping mechanism 402 is working, one of the mechanical grippers 209 clamps the blade plate 105 assembly from the insulating base plate conveying unit 401 to the first unloading seat 6, and the other two mechanical grippers 209 respectively clamp the molten sheets of the two molten sheet conveying units 400 and deliver them to the corresponding second unloading seats 605. Then, the assembly unit 7 assembles the blade plate 105 and the two molten sheets to obtain the blade body assembly 100.

[0067] The assembly unit 7 includes an electric slide rail 700 arranged above the base 4, an electric slider 701 adapted to the slide rail, and a drive seat 702 fixed above the slide rail. The drive seat 702 is an L-shaped structure and a flip gear ring 703 is rotatably provided at the center of the outer side of the vertical portion. The drive seat 702 is provided with a gear column 704 at the center of the flip gear ring 703. The gear column 704 includes a fixed first semicircular portion 705 and a movable second semicircular portion 706. A third power source 707 is horizontally provided on the inner bottom surface of the drive seat 702. The output shaft of the third power source 707 is connected to the second semicircular portion 706 through a connecting piece to drive the second semicircular portion 706 to move radially along the drive seat 702. Complex sliding, the right ends of the first semicircular portion 705 and the second semicircular portion 706 both have threaded segments 708, and in the initial state, the two threaded segments 708 form a complete matching pattern. The right end of the flip gear ring 703 is fixedly mounted with a flip body 709, which has two mounting bases 710, and a through-interval for the first semicircular portion 705 and the second semicircular portion 706 to pass through is formed between the two mounting bases 710. Two meshing tooth blocks 711 are correspondingly and rotatably arranged between the mounting bases 710 on both sides. The two meshing tooth blocks 711 are meshed with the threaded segments 708 of the first semicircular portion 705 or the second semicircular portion 706, and a clamping plate 712 is formed on one side of the two meshing tooth blocks 711.

[0068] A fourth driving source 713 is fixedly disposed inside the vertical portion of the driving seat 702 . The output shaft of the fourth driving source 713 passes through the driving seat 702 and is connected to a driving gear 714 . The driving gear 714 is meshed with the flip gear ring 703 .

[0069] During use, when assembling the tool body assembly 100, the ejector cylinder 603 drives the ejector plate 604 to eject the tool plate 105 located in the mounting recess 606 out of the mounting recess 606. The driving seat 702 moves towards the first material placing seat 6 through the driving cooperation of the electric slide rail 700 and the electric slider 701. After the clamping plate 712 clamps the tool plate 105, the driving seat 702 retracts to the initial position. Then, the two power cylinders 608 in the mounting recess 606 drive the pneumatic gripper 609 to move to the position of the fuse body and clamp the fuse body. After the pneumatic gripper 609 clamps the fuse body, the power cylinder 608 drives the pneumatic gripper 609 to move again. The pneumatic gripper 609 clamps the fuse body and moves towards the tool plate 105. The fuse is clamped and assembled with the tool plate 105 through the clamping component. After the fuse is clamped with the tool plate 105, the pneumatic gripper 609 cancels its clamping force on the fuse and the power cylinder 608 drives it to retract to the initial position to control the assembly of the driven fuse;

[0070] The flipping gear ring 703 is rotationally connected to the vertical part of the driving seat 702, and a flipping main body 709 is fixedly installed at the right end of the flipping gear ring 703. Two meshing tooth blocks 711 are correspondingly and rotationally arranged in the flipping main body 709. When the first semi-circular part 705 and the second semi-circular part 706 are in the initial state, the meshing tooth block 711 meshing with the first semi-circular part 705 always remains in the clamping state, and the meshing tooth block 711 meshing with the second semi-circular part 706 is in the non-clamping state. When it is necessary to clamp the workpiece with the two clamping plates 712, the third power source 707 (cylinder) is started. The third power source 707 drives the second semi-circular part 706 to slide backward. Through the meshing cooperation between the second semi-circular part 706 and the meshing tooth block 711 and the rotational cooperation between the meshing tooth block 711 and the flipping main body 709, the meshing tooth block 711 is driven to rotate and drive the corresponding clamping plate 712 to switch from the non-clamping state to the clamping state. Since the meshing tooth block 711 and the corresponding clamping plate 712 in meshing cooperation with the first semi-circular part 705 always remain in the clamping state, the two clamping plates 712 cooperate to form a clamping interval, and this clamping interval is adapted to the tool plate 105 to clamp the tool plate 105. When assembling the tool body assembly 100, the driving seat 702 moves towards the first material placing seat 6 through the driving cooperation of the electric slide rail 700 and the electric slider 701. After the two clamping plates 712 clamp the tool plate 105 through the above cooperation, the driving seat 702 retracts to the initial position;

[0071] After clamping the tool plate 105, start the fourth drive source 713 (servo motor) to drive the drive gear 714 to rotate. The drive gear 714 drives the flipping gear ring 703 to rotate left or right through the meshing cooperation with the flipping gear ring 703. When the flipping gear ring 703 rotates left, it drives the flipping body 709 and the tool plate 105 clamped by the flipping body 709 to rotate left. At this time, the position of the tool plate 105 corresponds to the second feeding seat 605 on one side. At this time, the power cylinder 608 and the pneumatic gripper 609 in the second feeding seat 605 clamp and drive the fuse piece body to move toward the tool plate 105 side to complete the assembly of one fuse piece. Similarly, the flipping body 709 drives the tool plate 105 to rotate right to the corresponding position of the other second feeding seat 605 to complete the assembly of the other fuse piece to obtain the tool body assembly 100. After completing the assembly of the tool body assembly 100, the third power source 707 drives the second semi-circular part 706 to retract to the initial position. At this time, the clamping force of the two clamping plates 712 on the tool body assembly 100 disappears, and the tool body assembly 100 then falls freely; the base 4 is provided with a discharge port at the position where the tool body assembly 100 is located. During actual work, a receiving box can be placed at the discharge port to collect the assembled tool body assembly 100;

[0072] It should be noted that both the right ends of the first semi-circular part 705 and the second semi-circular part 706 have threaded sections 708, and in the initial state, the two threaded sections 708 form a complete mating thread pattern, that is, the two semi-circular thread patterns are combined to form a complete circular thread pattern, and there are multiple spaced and arrayed circular thread patterns. When the third power source 707 drives the second semi-circular part 706 to change its position to make the two clamping plates 712 in a clamped state, the second semi-circular part 706 also forms a complete circular thread pattern with the first semi-circular part 705. Therefore, when the flipping gear ring 703 drives the flipping body 709 to rotate, the thread patterns of the first semi-circular part 705 or the second semi-circular part 706 will not cause jamming to the two meshing tooth blocks 711 and ensure that the two meshing tooth blocks 711 are stably held in a clamped state.
