Description

Technical Field

[0001] This application relates to the technical field of metal processing, and in particular to a fully automatic drilling and tapping device. Background Technology

[0002] Currently, non-standard threaded fasteners are frequently used in hardware product processing. Unlike common nuts, these threaded fasteners are used in applications specific to the product's structure and lack universality. Therefore, their shapes may be rectangular, triangular, or other non-hexagonal, and they may also be sheet-like. Furthermore, due to rapid product updates, these threaded fasteners cannot be mass-produced, leading to supply difficulties. Because they are non-standard parts, their procurement costs are relatively high. Therefore, manufacturers typically purchase metal parts themselves as raw materials for punching and processing.

[0003] In related technologies, when processing threaded fasteners independently, it is necessary to first punch holes using a punching machine and then tap them using a tapping machine. Both of these steps require manual operation. Furthermore, after the metal parts are punched, they need to be manually transported to the tapping machine for tapping. This method is labor-intensive and inefficient, and therefore needs to be improved. Summary of the Invention

[0004] The purpose of this application is to provide a fully automatic drilling and tapping device, which has the effect of improving the processing efficiency of non-standard threaded fasteners.

[0005] The present application provides a fully automatic drilling and tapping device, which adopts the following technical solution.

[0006] A fully automatic drilling and tapping device, comprising:

[0007] The frame is used to provide support and load-bearing function, and the frame has a loading station, a punching station, a tapping station and a unloading station;

[0008] An automatic feeding assembly, wherein the discharge end of the automatic feeding assembly is connected to the feeding station, and the automatic feeding assembly is used to automatically supply metal parts;

[0009] A punching assembly, which is mounted on a frame, is used to automatically punch metal parts located at a punching station.

[0010] A tapping assembly, which is mounted on a frame, is used to automatically tap metal parts located at a tapping station.

[0011] And a transfer assembly, which is mounted on the frame and is used to drive the metal parts located in the loading station to be transferred sequentially between the punching station, the tapping station and the unloading station.

[0012] By adopting the above technical solution, a large number of metal parts are placed in the automatic feeding assembly. The automatic feeding assembly vibrates the metal parts one by one at a specified angle, so that the metal parts can fall onto the feeding station of the frame. Then, the transfer assembly drives the metal parts to the punching station and the tapping station in sequence, so that the punching assembly and the tapping assembly can perform corresponding punching and tapping processing on the metal parts, thereby realizing the processing and forming of non-standard threaded fasteners. Finally, the transfer assembly drives the non-standard threaded fasteners to the unloading station for collection.

[0013] Optionally, the transfer component includes:

[0014] The transfer rod is movably mounted on the frame. The moving direction of the transfer rod is set along the length direction of the transfer rod. The transfer rod is provided with two positioning grooves. The punching station and the tapping station are respectively located on the two long sides of the transfer rod.

[0015] The first translation mechanism, the first push mechanism is used to control the transfer of the metal part between the transfer rod and the punching station;

[0016] And a second translation mechanism, which controls the transfer of the metal part between the transfer rod and the tapping station;

[0017] When the transfer rod moves back and forth, one of the positioning grooves can communicate with the loading station or the punching station, and the other positioning groove can communicate with the punching station or the tapping station.

[0018] By adopting the above technical solution, and utilizing the cooperation between the transfer rod and the loading station, punching station and tapping station, when the transfer rod moves horizontally, the metal part can be transferred between the transfer rod and the punching station using the first translation mechanism, or the metal part can be transferred between the transfer rod and the tapping station using the second translation mechanism.

[0019] Optionally, the first translation mechanism includes two first cylinders located on opposite sides of the transfer rod and the punching station, with the piston rods of the two first cylinders arranged opposite to each other;

[0020] When the transfer rod moves to the end away from the loading station, the positioning groove near the loading station is connected to the punching station and is located between the two first cylinders.

[0021] By adopting the above technical solution, when the positioning groove on the transfer rod is in communication with the punching station, by controlling the piston rod of the corresponding first cylinder to push out, the metal part can be pushed back and forth between the positioning groove and the punching station. Furthermore, when the piston rods of both first cylinders are tightly attached to the outer wall of the metal part, they can clamp and fix the metal part, allowing the metal part to be quickly fixed at the punching station for punching processing.

[0022] Optionally, the second translation mechanism includes two second cylinders located on opposite sides of the transfer rod and the tapping station, with the piston rods of the two second cylinders arranged opposite to each other;

[0023] When the transfer rod moves to the end away from the loading station, the positioning groove, punching station and unloading station away from the loading station are connected in sequence and are all located between the two second cylinders.

[0024] By adopting the above technical solution, when the positioning groove on the transfer rod is in communication with the tapping station, by controlling the piston rod of the corresponding second cylinder to push out, the metal part can be moved from the positioning groove to the tapping station. Furthermore, when the piston rods of both second cylinders are tightly fitted with the outer wall of the metal part, they can clamp and fix the metal part, allowing the metal part to be quickly fixed at the tapping station for punching. Moreover, when the piston rod of the second cylinder away from the transfer rod is in a retracted state, and the piston rod of the second cylinder close to the transfer rod continues to push out, it can also push the non-standard threaded fastener at the tapping station to the unloading station.

[0025] Optionally, the frame is provided with a movable slot that sequentially connects the loading station, punching station, tapping station, and unloading station, and the transfer assembly includes:

[0026] A fluid feeding mechanism includes a water pump and a filter box. The water inlet of the filter box is connected to the unloading station, the water inlet of the water pump is connected to the water outlet of the filter box, and the water outlet of the water pump is connected to one end of the movable trough that is connected to the loading station.

[0027] And an electromagnetic adsorption mechanism, wherein two electromagnetic adsorption mechanisms are provided, and the two electromagnetic adsorption mechanisms are respectively installed at the punching station and the tapping station. The electromagnetic adsorption mechanism is used to temporarily adsorb and fix the metal parts that have been moved to the punching station or the tapping station.

[0028] The filter box contains water-based cooling oil.

[0029] By adopting the above technical solution, a fluid feeding mechanism continuously injects water-based cooling oil into the movable groove. The water-based cooling oil can push the metal part to move along the length of the movable groove, so that the metal part can pass through the punching station and the tapping station in sequence, and finally fall into the unloading station. When the metal part moves to the punching station and the tapping station, the electromagnetic adsorption mechanism is used to adsorb and fix the metal part, so as to facilitate the processing of the punching and tapping components. The water-based cooling oil not only can push the metal part to move, but also can cool and lubricate the metal part and the processing head during punching and tapping.

[0030] Optionally, the transfer component further includes:

[0031] An exhaust pipe is installed inside the frame, and the installation path of the exhaust pipe is the same as the extension path of the movable slot.

[0032] And an air pump, wherein the air outlet of the air pump is connected to one end of the exhaust pipe, and the end of the exhaust pipe away from the air pump is closed.

[0033] The bottom of the movable groove is provided with several air blowing holes that communicate with the inside of the exhaust pipe, and each air blowing hole is arranged along the length of the movable groove.

[0034] By adopting the above technical solution, the air pump can inject compressed air into the exhaust pipe. Through the cooperation between the exhaust pipe and the movable groove, air can be blown onto the moving metal parts in the movable groove, avoiding the situation where the metal parts stick to the movable groove due to the high viscosity of the lubricating oil, thus ensuring the safe transportation of the metal parts.

[0035] Optionally, the electromagnetic adsorption mechanism includes:

[0036] An electromagnet is provided, and two electromagnets are installed in the bottom of the movable groove, and the two electromagnets are respectively located near the two ends of the movable groove.

[0037] And lifting and positioning components, wherein several lifting and positioning components are provided, and each lifting and positioning component is installed at the bottom of the movable groove in a lifting and lowering manner, and each lifting and positioning component is respectively positioned close to two electromagnets.

[0038] When the electromagnet is energized and generates magnetic force, the lifting and positioning component is attracted by the magnetic force and can rise so that the upper end of the lifting and positioning component extends beyond the bottom surface of the movable groove, and the part of each lifting and positioning component extending beyond the bottom surface of the movable groove can abut against the edge of the metal part.

[0039] By adopting the above technical solution, during normal use, the electromagnet near the unloading station is energized to raise the lifting and positioning components near the unloading station. When the metal part approaches the corresponding processing station, the outer wall of the metal part can abut against the corresponding lifting and positioning component, achieving the initial positioning of the metal part. Then, the electromagnet near the loading station is energized to raise the lifting and positioning components near the loading station, so that the lifting and positioning components can work together to easily position the metal block. At the same time, the two electromagnets can also generate a strong adsorption force on the metal part, so that the metal part is firmly adsorbed and fixed at the bottom of the movable slot, so that the punching or tapping components can process it.

[0040] Optionally, the lifting and positioning component includes:

[0041] A plastic limiting rod is provided, wherein the plastic limiting rod is vertically arranged and the lower end of the plastic limiting rod is inserted into the bottom of the movable groove;

[0042] And a magnetic metal block, which is disposed on one side of the plastic limiting rod and is located directly below the electromagnet;

[0043] The bottom of the movable groove is provided with several lifting grooves, and each of the lifting positioning components is installed in each lifting groove.

[0044] By adopting the above technical solution, when the electromagnet is energized and generates magnetic force, it can attract the magnetic metal block to move upward. When the magnetic metal block moves upward, it can drive the plastic limiting rod to rise, so that the upper end of the plastic limiting rod can extend beyond the bottom surface of the movable groove, thereby achieving the effect of limiting the metal part.

[0045] Optionally, the lifting slot includes:

[0046] The upper end of the first vertical groove is connected to the bottom surface of the movable groove;

[0047] And a second vertical slot, which is located directly below the electromagnet and is connected to the second vertical slot;

[0048] When the lifting and positioning component is installed on the lifting groove, the plastic limiting rod is installed in the first vertical groove in a lifting manner, and the magnetic metal block is installed in the second vertical groove in a lifting manner, with part of the magnetic metal block extending into the first vertical groove. A connecting groove is provided on the side of the plastic limiting rod near the second vertical groove, and the lower end of the connecting groove communicates with the bottom surface of the plastic limiting rod. The part of the magnetic metal block located in the first vertical groove is inserted into the connecting groove and is interference-fitted with the connecting groove.

[0049] By adopting the above technical solution, the plastic limiting rod and the magnetic metal block can be detachably connected, so that the corresponding plastic limiting rod can be replaced according to the contour shape of the metal part. When replacing the plastic limiting rod, simply pull the old plastic limiting rod upward, and then insert the new plastic limiting rod into the first vertical groove, so that the plastic limiting rod and the part of the magnetic metal block extending into the first vertical groove are connected.

[0066] The following is in conjunction with the appendix Figure 1 - Appendix Figure 11 This application will be described in further detail below.

[0067] Example 1:

[0068] A fully automatic drilling and tapping device, as described in the reference Figure 1 The system includes a frame 1, an automatic feeding assembly 2, a punching assembly 3, a tapping assembly 4, and a transfer assembly 5. The frame 1 serves as a support and load-bearing component. The punching assembly 3, the tapping assembly 4, and the transfer assembly 5 are all mounted on the frame 1. The frame 1 is equipped with a feeding station, a punching station, a tapping station, and a unloading station. The discharge end of the automatic feeding assembly 2 is connected to the feeding station for automatically feeding metal parts. The punching assembly 3 is used to automatically punch the metal parts located at the punching station. The tapping assembly 4 is used to automatically tap the metal parts located at the tapping station. The transfer assembly 5 is used to drive the metal parts located in the feeding station to be transferred sequentially between the punching station, the tapping station, and the unloading station.

[0069] Reference Figure 1, on one side edge of the upper surface of the frame 1, a back baffle 11 is provided. The loading station is located on one side of the frame 1 close to the back baffle 11, and the unloading station is located on the side of the frame 1 far from the back baffle 11. On the two opposite side edges of the upper surface of the frame 1, side baffles 12 are also provided. The two side baffles 12 are respectively arranged at both ends of the back baffle 11, so that the back baffle 11 and the side baffles 12 can be combined to form a protective cover with a "U" shape when viewed from above.

[0070] Refer to Figure 1 , the automatic loading component 2 is set as a vibrating disk. The vibrating disk is installed outside the frame 1, and the discharge port of the vibrating disk is communicated with the loading station through a conveying groove 21 with a "U" shaped cross-section.

[0071] Refer to Figure 2 , on the upper surface of the frame 1, an activity groove 13 that successively communicates the loading station, the punching station, the tapping station and the unloading station is provided; among them, on the two long side edges of the activity groove 13, several blocks 14 are provided. The activity groove 13 is formed by enclosing the surface of the frame 1 by the blocks 14. The transfer component 5 is used to drive the metal parts to move in the activity groove 13.

[0072] In the embodiment of the present application, the punching station and the tapping station are respectively located on the two long side edges of the activity groove 13. On the upper surface of the frame 1, two transfer grooves 141 are also provided. One ends of the two transfer grooves 141 are both communicated with the activity groove 13. The punching station and the tapping station are respectively located at one ends of the two transfer grooves 141 far from the activity groove 13; among them, the transfer groove 141 is arranged on the corresponding blocks 14.

[0073] Refer to Figure 3 and Figure 4 , the punching component 3 includes an automatic punching machine 31 and a dust-proof cover 32 installed on the frame 1. The lower end of the dust-proof cover 32 is provided with an opening, and the dust-proof cover 32 covers the punching station. The punch of the automatic punching machine 31 extends from the upper side of the dust-proof cover 32 into the dust-proof cover 32 and is arranged to aim at the punching station; the tapping component 4 includes an automatic tapping machine 41 and a limiting plate 42 installed on the frame 1. The limiting plate 42 is located directly above the tapping station, and both sides of the limiting plate 42 are fixedly connected to the top surfaces of the adjacent blocks 14 respectively. The tapping tool of the automatic tapping machine 41 can penetrate through the limiting plate 42.

[0074] When the metal part moves to the punching station for punching processing, the dust-proof cover 32 can be used to avoid a large amount of powder generated during the punching process from directly overflowing. When the metal part moves to the tapping station for tapping processing, the limiting plate 42 can be used to prevent the metal part from rising when the tapping tool retracts, and avoid the metal part from disengaging from the tapping station.

[0075] Refer to Figure 2 and Figure 5The transfer assembly 5 includes a transfer rod 51, a first translation mechanism 52, and a second translation mechanism 53. The transfer rod 51 is movably mounted on the movable slot 13, and the moving direction of the transfer rod 51 is set along the length direction of the movable slot 13. A translation cylinder 512 for controlling the back-and-forth translation of the transfer rod 51 is installed on the frame 1. Two positioning slots 511 for temporary positioning of metal parts are provided on the transfer rod 51. The first translation mechanism is used to control the transfer of metal parts between the transfer rod 51 and the punching station, and the second translation mechanism 53 is used to control the transfer of metal parts between the transfer rod 51 and the tapping station.

[0076] When the transfer rod 51 moves back and forth, one of the positioning grooves 511 can communicate with the loading station or the punching station, and the other positioning groove 511 can communicate with the punching station or the tapping station.

[0077] Reference Figure 5 The first translation mechanism 52 includes two first cylinders 521 mounted on the frame 1. The two first cylinders 521 are located on opposite sides of the movable groove 13 and the punching station, respectively. The piston rods of the two first cylinders 521 are arranged opposite to each other, and the piston rods of the two first cylinders 521 can extend into the transfer groove 141 where the punching station is located. The first cylinder 521 closer to the punching station is mounted outside the dust cover 32, and the piston rod of the first cylinder 521 extends into the dust cover 32.

[0078] When the transfer rod 51 moves to the end away from the loading station, the positioning groove 511 near the loading station communicates with the punching station. At this time, by controlling the piston rod of the first cylinder 521 near the movable groove 13 to push out, the metal part located on the transfer rod 51 can be pushed to the punching station. At this time, the piston rods of both first cylinders 521 can be tightly fitted with the outer wall of the metal part to achieve the effect of clamping and fixing the metal part. After the metal part is punched, the piston rod of the first cylinder 521 near the movable groove 13 is controlled to retract, and then the piston rod of the first cylinder 521 near the punching station is controlled to push out, so that the punched metal part can be pushed back onto the transfer rod 51.

[0079] It should be noted that during the punching process of the metal part, the translation rod is controlled to reset so that the positioning groove 511 near the unloading station can communicate with the punching station. This allows the punched metal part to be pushed back onto the transfer rod 51, and when the transfer rod 51 moves again toward the unloading station, it can move the punched metal part to the position where it communicates with the tapping station.

[0080] Reference Figure 5The second translation mechanism 53 includes two second cylinders 531 mounted on the frame 1. The two second cylinders 531 are located on opposite sides of the movable groove 13 and the unloading station, respectively. The piston rods of the two second cylinders 531 are arranged opposite each other, and the piston rods of both second cylinders 531 can extend to a position close to the tapping station. The unloading station, the tapping station and the two second cylinders 531 are arranged in a straight line, and the unloading station and the tapping station are both located between the two second cylinders 531. When the piston rod of the second cylinder 531 near the unloading station is fully extended, the metal part located at the tapping station abuts against the piston rod of the second cylinder 531. When the piston rod of the second cylinder 531 near the movable groove 13 is fully extended, the piston rod of the second cylinder 531 passes through the tapping station.

[0081] When the transfer rod 51 moves to the end away from the loading station, the positioning groove 511 away from the loading station is connected to the tapping station. At this time, by controlling the piston rods of the two second cylinders 531 to push out, and making the piston rod of the second cylinder 531 near the unloading station fully extended, the metal part on the transfer rod 51 can be pushed to the tapping station. At this time, the piston rods of the two second cylinders 531 can be tightly fitted with the outer wall of the metal part to achieve the effect of clamping and fixing the metal part. After the metal part is tapped, the piston rod of the second cylinder 531 near the unloading station is controlled to retract, and then the piston rod of the second cylinder 531 near the movable groove 13 is controlled to fully extend, so that the non-standard bolt fastening part that has been tapped can be pushed out of the tapping station, so that the non-standard bolt fastening part can fall directly into the unloading station.

[0082] Reference Figure 6 A material discharge port 15 is provided on the upper side of the frame 1. The material discharge port 15 is used as a material unloading station. The material discharge port 15 is located on the side of the tapping station away from the movable groove 13, so that the non-standard bolt fastening parts after being formed can fall directly into the material discharge port 15 after leaving the tapping station. An inclined material unloading trough is installed in the frame 1. The upper end of the material unloading trough is connected to the material discharge port 15, and the lower end of the material unloading trough extends out of the side of the frame 1. Several filter grooves (not shown in the figure) are provided on the bottom surface of the material unloading trough.

[0083] The implementation principle of this application embodiment is as follows:

[0084] A large number of metal parts are placed in the automatic feeding assembly 2. The automatic feeding assembly 2 vibrates the metal parts one by one at a specified angle so that the metal parts can fall onto the feeding station of the frame 1. Then, the transfer assembly 5 drives the metal parts to the punching station and the tapping station in sequence so that the punching assembly 3 and the tapping assembly 4 can perform the corresponding punching and tapping processing on the metal parts, thereby realizing the processing and forming of non-standard threaded fasteners. Finally, the transfer assembly 5 drives the non-standard threaded fasteners to the unloading station for collection.

[0085] Example 2:

[0086] Reference Figure 7 The difference between this embodiment and Embodiment 1 is that both the punching station and the tapping station are located on the extension path of the movable groove 13, the bottom surface of the movable groove 13 is inclined, and the end of the movable groove 13 near the loading station is higher than the end of the movable groove 13 near the unloading station; wherein, the transfer component 5 includes a fluid pushing mechanism 54, an airflow assist mechanism 55, and an electromagnetic adsorption mechanism 56. Figure 6 (Not marked in the text) The fluid pushing mechanism 54 can generate flowing water-based cooling oil in the movable tank 13, and use the water-based cooling oil to push the metal parts to move in the movable tank 13. The airflow auxiliary mechanism 55 is used to cooperate with the fluid pushing mechanism 54 to push the metal parts to move. Two electromagnetic adsorption mechanisms 56 are provided, and the two electromagnetic adsorption mechanisms 56 are respectively installed at the punching station and the tapping station. The electromagnetic adsorption mechanisms 56 are used to temporarily adsorb and fix the metal parts to the bottom surface of the movable tank 13.

[0087] Reference Figure 7 and Figure 8 The fluid feeding mechanism 54 includes a water pump 541, a filter box 542, and a rubber tube 543. The filter box 542 has an opening at its upper end and is installed inside the frame 1. The upper opening of the filter box 542 is located directly below the unloading station. Several filter screens are installed inside the filter box 542. The water inlet of the water pump 541 is connected to the water outlet of the filter box 542. The water outlet of the water pump 541 is connected to the end of the movable trough 13 connected to the loading station through the rubber tube 543.

[0088] When water-based cooling oil and non-standard threaded fasteners fall from the unloading station, the unloading chute can be used to separate the non-standard threaded fasteners and water-based cooling oil. The non-standard threaded fasteners fall outside the frame 1 through the unloading chute, while the water-based cooling oil falls into the filter box 542 for filtration. After filtration, the water-based cooling oil is returned to the movable tank 13 by the water pump 541 for use.

[0089] Reference Figure 7 and Figure 9The airflow auxiliary mechanism 55 includes an exhaust pipe 551 and an air pump 552. The exhaust pipe 551 is laid inside the frame 1, and the laying path of the exhaust pipe 551 is the same as the extension path of the movable groove 13. The air pump 552 is installed inside the frame 1, and the air outlet end of the air pump 552 is connected to the exhaust pipe 551. The end of the exhaust pipe 551 away from the air pump 552 is closed. Several air blowing holes 131 are arranged along the length of the movable groove 13 and are connected to the interior of the exhaust pipe 551 on the bottom of the movable groove 13. The upper end of each air blowing hole 131 is inclined towards the direction close to the unloading station.

[0090] Reference Figure 10 The electromagnetic adsorption mechanism 56 includes an electromagnet 561 and a lifting positioning component 562. Two electromagnets 561 are arranged in a semi-circular ring shape at the bottom of the movable groove 13, and both electromagnets 561 are embedded in the bottom of the movable groove 13. The two electromagnets 561 are respectively arranged near the two ends of the movable groove 13. Several lifting positioning components 562 are arranged that can be raised and lowered, and each lifting positioning component 562 is arranged near the two electromagnets 561. Each lifting positioning component 562 is installed in the top of the movable groove 13. When the electromagnet 561 is de-energized, the lifting positioning component 562 is completely retracted into the bottom of the movable groove 13 under the action of gravity. When the electromagnet 561 is energized and generates magnetic force, the upper end of each lifting positioning component 562 can be controlled to extend out of the bottom surface of the movable groove 13 by magnetic force, so that the part of the lifting positioning component 562 extending out of the bottom surface of the movable groove 13 can abut against the edge of the metal part.

[0091] It should be noted that a clearance hole 132 is provided on the bottom surface of the movable groove 13 between the two electromagnets 561. When the punching assembly 3 or the tapping assembly 4 is working, the lower end of the punching cutter or the tapping cutter can pass through the clearance hole 132 at the corresponding position.

[0092] Reference Figure 10 and Figure 11The lifting and positioning component 562 includes a plastic limiting rod 563 and a magnetic metal block 564. The plastic limiting rod 563 is vertically arranged, and a connecting groove 565 is provided on one of its vertical sides. The lower end of the connecting groove 565 communicates with the bottom surface of the plastic limiting rod 563. The magnetic metal block 564 is disposed on one side of the plastic limiting rod 563, and part of the magnetic metal block 564 is inserted into the connecting groove 565, with the portion of the magnetic metal block 564 inserted into the connecting groove 565 having an interference fit with the inner wall of the connecting groove 565. The mechanism includes a lifting groove at the bottom of the movable groove 13 for installing the lifting positioning component 562. Each lifting groove includes a first vertical groove 133 and a second vertical groove 134 that are interconnected. The upper end of the first vertical groove 133 is connected to the bottom surface of the movable groove 13. The second vertical groove 134 is located directly below the electromagnet 561. When the lifting positioning component 562 is installed on the lifting groove, the plastic limiting rod 563 can be lifted and installed on the first vertical groove 133, and the magnetic metal block 564 can be lifted and installed in the second vertical groove 134.

[0093] The implementation principle of this application embodiment is as follows:

[0094] A fluid feeding mechanism 54 continuously pumps water-based cooling oil into the movable groove 13. The water-based cooling oil propels the metal part along the length of the movable groove 13. A gas-assisted mechanism reduces the friction between the metal part and the bottom surface of the movable groove 13, allowing the metal part to pass through the punching station and the tapping station in sequence, and finally fall into the unloading station. When the metal part moves to the punching station and the tapping station, the electromagnetic adsorption mechanism 56 adsorbs and fixes the metal part, so that the punching assembly 3 and the tapping assembly 4 can process it. The water-based cooling oil not only propels the metal part, but also cools and lubricates the metal part and the cutting head during punching and tapping.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
