[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] like Figures 1 to 10As shown, the present invention is an automated assembly device for a micro motor, the micro motor comprises a housing 10, a magnetic sheet 11 and a pin 12, wherein a positioning block 100 is symmetrically arranged in the housing 10, the magnetic sheet 11 is arranged in an arc shape, and both ends of the pin 12 are formed with a deformable flange 120, the automated assembly device comprises: a spiral conveying mechanism 2, on which a feeding area 20 and an orientation area 21 are arranged, the feeding area 20 is used to sequentially convey a plurality of housings 10 to the orientation area 21 in a horizontal posture, and the orientation area 21 adjusts the open end of the shell 10 to the back side of its moving direction; the positioning mechanism 3 is arranged on one side of the positioning area, and the positioning mechanism 3 is used to adjust the open end of the shell 10 to be vertically upward, so that the positioning mechanism 3 can extend into the shell 10 and drive it to rotate to the assembly position; the magnetic sheet conveying mechanism 4 and the first assembly mechanism 5, the magnetic sheet conveying mechanism 4 is used to convey the magnetic sheet 11 to its end in a vertical posture, so that the two magnetic sheets 11 are symmetrical and spaced apart; the first assembly mechanism 5 is movably provided with a magnetic pressing block 50 and a magnetic The magnetic blocks 51 are raised and symmetrically arranged on both sides of the magnetic pressing block 50, and the distance between the two magnetic blocks 51 is equal to the spacing between the two magnetic sheets 11, so that the magnetic sheets 11 can be movably attached to the side wall of the magnetic pressing block 50 due to the adsorption of the magnetic blocks 51, so that the magnetic sheets 11 can be movably inserted and attached to the inner wall of the shell 10 to form a semi-finished product; the vibration plate 6 and the second assembly mechanism 7, the vibration plate 6 is used to transport a plurality of pins 12 to its end in a vertical posture, and the second assembly mechanism 7 has a function of being able to be in a magnetized state and a demagnetized state. The profiling block 70 switches between the states. The profiling block 70 in the magnetized state is used to absorb the end of the pin 12. The flange 120 can be squeezed and deformed when the pin 12 slides between the two magnetic sheets 11, allowing the pin 12 to be inserted into the housing 10, and the magnetic sheet 11 can be moved against the positioning block 100 due to the elastic reset after switching to the demagnetized state; the feeding mechanism 8 is arranged below the first assembly mechanism 5 and the second assembly mechanism 7. The feeding mechanism 8 is used to grab the housing 10 and drive it to move along the outside of the equipment to unload materials.

[0022] It is worth noting that Figure 1 As shown, in this embodiment, deformable flanges 120 (similar to elastic buckle structures) are added on both sides of the pin 12. The flanges 120 can accurately press the magnetic sheet 11 against the positioning block 100 through their own elastic deformation during the assembly process to ensure the accuracy of the overall assembly of the micromotor; specifically, as Figures 2 to 10As shown, several shells 10 can be transported to the orientation zone 21 in a horizontal posture in sequence through the feeding zone 20 of the spiral conveying mechanism 2, and the open end of the shell 10 is adjusted to the back side of its moving direction under the positioning action of the orientation zone 21. When the positioning mechanism 3 adjusts the open end of the shell 10 to be vertically upward, the positioning mechanism 3 can extend into the shell 10 and rotate the shell 10 to a preset position to be assembled through a rotating action; at the same time, the magnetic sheet 11 is sent to its end in a vertical posture through the conveying mechanism, and when the two magnetic sheets 11 are symmetrically and spaced apart, the magnetic pressing block 50 and the magnetic suction block 51 on the first assembly mechanism 5 start to work, and the magnetic suction block 51 is used to absorb the magnetic sheet 11 so that it is tightly attached to the side wall of the magnetic pressing block 50 (it should be noted that the magnetic suction block 51 is symmetrically arranged on both sides of the magnetic pressing block 50 and matches the spacing between the two magnetic sheets 11). Subsequently, the magnetic pressing block 50 accurately inserts the magnetic sheet 11 into the adjusted shell 10 and tightly attaches it. The inner wall of the housing 10 forms a preliminary semi-finished product; similarly, a plurality of pins 12 are conveyed at their ends in a vertical posture through the vibration plate 6. After the semi-finished product is assembled and formed, the profiling block 70 in the second assembly mechanism 7 is switched to a magnetized state to adsorb the pin 12 at its end to ensure that the pin 12 will not be displaced relative to the profiling block 70 during the assembly process. When the profiling block 70 drives the pin 12 to slide between the two magnetic sheets 11, the flanges 120 at both ends of the pin 12 are squeezed and deformed, which facilitates the smooth insertion of the pin 12 into the housing 10; and after the pin 12 is fully inserted into the housing 10, the profiling block 70 is switched to a demagnetized state, and the flanges 120 at both ends of the pin 12 are restored to their original state under the action of elasticity, thereby pressing the magnetic sheet 11 against the positioning block 100 in the housing 10 (i.e., the finished product required for assembly and forming). Finally, the assembled micromotor housing 10 can be grabbed by the feeding mechanism 8 and moved along the outside of the equipment to the unloading area to complete the entire assembly process. It can be seen that the equipment has achieved seamless connection from raw material supply to finished product output by integrating multiple automated mechanisms, without the need for human intervention throughout the entire process. It not only shortens the product assembly cycle time and improves the overall assembly efficiency, but also effectively reduces production costs and labor intensity, ensuring that each component can be installed accurately and correctly, thereby improving the overall quality and reliability of the product.

[0023] The positioning mechanism 3 includes: a conveyor belt 30 and a baffle 31 arranged on one side of the conveyor belt 30; a flip motor 32, which is arranged at the end of the conveyor belt 30, and the output end of the flip motor 32 is connected to a flip block 320, and the flip block 320 is used to receive and adsorb the shell 10 to flip the shell 10 to a vertical posture and place it on the conveyor belt 30; a locking cylinder 33, which is arranged on one side of the conveyor belt 30, and the output end of the locking cylinder 33 is connected to a locking block 330, and the locking block 330 is used to movably press the shell 10 against the baffle 31 to limit the movement of the shell 10; a rotating component 34, which is arranged above the baffle 31, and the output end of the rotating component 34 is connected to a symmetrically arranged clamping block 340, and the clamping block 340 is used to extend into the shell 10 and press against the inner wall of the shell 10, so that the rotating component 34 drives the shell 10 to rotate to the assembly position.

[0024] like Figure 2 , Figure 4 as well as Figure 5 As shown, it should be noted that the flip block 320 in this embodiment is provided with a magnetic block 51 (not shown in the figure) and a position sensor (not shown in the figure). When the shell 10 whose opening end is on the back side of the moving direction is transferred to the flip block 320, the shell 10 can be adsorbed in the flip block 320 through the magnetic block 51. At the same time, after the position sensor performs position detection, the flip motor 32 can drive the flip block 320 to rotate, and then the shell 10 in the flip block 320 is placed on the conveyor belt 30 in a vertical posture. When the conveyor belt 30 drives the shell 10 to move to the bottom of the clamping block 340, the locking cylinder 340 is engaged. 3 can push the locking block 330 to move toward the housing 10, and finally press the housing 10 against the baffle 31, thereby limiting the movement of the housing 10 on the conveyor belt 30, and providing a guarantee for the stability of the subsequent assembly action; with the start of the rotating assembly 34, the clamping block 340 can extend into the housing 10, and press against the inner wall of the housing 10, thereby driving the housing 10 to rotate to the above-mentioned assembly position (that is, the positioning block 100 is at the side of the housing 10 away from the baffle 31 at this time), and the clamping block 340 is used to maintain the pressure on the inner wall of the housing 10 to ensure that the housing 10 will not deviate during the rotation process.

[0025] Preferably, if Figure 2 As shown, the conveyor belt 30 in this embodiment is composed of two belts, one side of each belt is fixedly connected with the above-mentioned baffle 31, and each belt is connected to a cylinder. The cylinder pushes the belt to move, and the distance between the two baffles 31 can be adjusted to adapt to the assembly operation of micromotor housings 10 of different sizes, thereby improving the flexibility during assembly.

[0026] The rotating assembly 34 also includes: a rotating motor 341, whose output end is connected to a worm 342; a worm wheel 343 and a driving member 344, the worm wheel 343 is movably engaged with the worm 342, and a mounting seat 345 is connected to the bottom of the worm wheel 343, and the driving member 344 is arranged in the mounting seat 345; a spiral block 346, which is connected to the driving end of the driving member 344, and the clamping block 340 is movably clamped to the spiral block 346, so that when the driving member 344 drives the spiral block 346 to rotate, the two clamping blocks 340 can move closer to or away from each other.

[0027] like Figure 2 , Figure 4 as well as Figure 5 As shown, when the housing 10 is pressed against the baffle 31 through the locking block 330, the driving member 344 can drive the spiral block 346 to rotate synchronously when rotating. The rotation of the spiral block 346 causes the clamping block 340 to move toward each other along the track of the spiral block 346 through the threaded structure. As the spiral block 346 continues to rotate, the clamping block 340 further penetrates into the interior of the housing 10 until the two clamping blocks 340 gradually move away from each other and press against the inner wall of the housing 10; at this time, the rotating motor 341 starts to rotate, and the mounting seat 345 is driven to rotate by the coordinated meshing rotation of the worm 342 and the worm wheel 343, and finally drives the housing 10 to rotate to the above-mentioned assembly position. It should be noted that the rotating assembly 34 can efficiently and accurately adjust the housing 10 to the desired assembly position, providing necessary preparations for the subsequent assembly of the magnetic sheet 11 and the pin 12. In addition, the overall structure and working principle of the rotating assembly 34 are the same as those of the three-jaw chuck in the machine tool, which will not be described in detail here.

[0028] The feeding area 20 includes: a conveying box 200, wherein a feed port 201 and a discharge port 202 are respectively arranged at the top and the bottom, wherein the feed port 201 is arranged in a conical shape, the discharge port 202 is arranged in a fan shape, and a plurality of cloth belts 202a are arranged at the discharge port 202; a spiral motor 203 and a spiral bar 204, wherein the spiral motor 203 is arranged on one side of the conveying box 200 close to the feed port 201; a central column 205 is arranged in the conveying box 200, wherein one end of the spiral bar 204 is connected to the output end of the spiral motor 203, and the other end is loosely matched with the central column 205, and a guide cavity 205a is formed together by the end of the spiral bar 204 away from the spiral motor 203, the central column 205 and the inner wall of the conveying box 200.

[0029] like Figures 2 to 3As shown, when the interior of the conveying box 200 is in a hollow state, the operator puts several shells 10 into the conveying box 200 through the feed port 201, wherein the conical feed port 201 design makes it easier for the material to be concentrated and smoothly enter the conveying box 200, as the spiral motor 203 drives the spiral bar 204 to rotate, several shells 10 can move along the guide cavity 205a on the right side driven by the rotation of the spiral bar 204, it should be noted that the design of the guide cavity 205a makes the shells 10 evenly distributed, and under the action of the spiral bar 204, the shells 10 can be effectively guided to be smoothly pushed to the discharge port 202, and the fan-shaped discharge port 202 design helps the shells 10 to be discharged smoothly, and cooperates with the design of several cloth belts 202a to ensure that the shells 10 are discharged one by one through the discharge port 202 to the directional area 21, preferably, a vibration motor (not shown in the figure) can also be provided at the discharge port 202 in this embodiment, and the vibration function of the vibration motor on the discharge port 202 can effectively avoid the blockage caused by too many shells 10.

[0030] The orienting area 21 includes a mounting bracket 210 and a hook block 211, and the spiral conveying mechanism 2 also includes a conveyor belt 22. The two ends of the conveyor belt 22 are respectively close to the discharge port 202 and the flip motor 32. The mounting bracket 210 is connected to the side wall of the conveyor belt 22, and the blocking blocks 212 are symmetrically arranged on the mounting bracket 210. The hook block 211 is provided with a connecting sleeve 213, and the connecting sleeve 213 is movably mounted on the mounting bracket 210, and the movement of the hook block 211 is limited by the blocking block 212, so that the hook block 211 can rotate relative to the mounting bracket 210.

[0031] like Figures 2 to 4 As shown, when the shells 10 arrive at the conveyor belt 22 one by one through the discharge port 202, as the conveyor belt 22 runs, if the open end of the shell 10 faces the same direction as the moving direction of the conveyor belt 22, the shell 10 is hooked by the hook block 211. As the conveyor belt 22 continues to transport the shell 10, the shell 10 relies on the rotation and pulling of the hook block 211 to flip to 180 degrees relative to the conveyor belt 22, and finally makes the open end of the shell 10 face the opposite direction of the moving direction of the conveyor belt 22. It should be noted that the hook block 211 cannot rotate and pull the shell 10 when the shell 10 is in the correct assembly position, that is, there is no need to adjust the position of the shell 10. During the process of the hook block 211 applying rotation and pulling to the shell 10, the limit block on the mounting bracket 210 can effectively limit the hook block 211 from linear displacement, thereby ensuring the accuracy and stability of the directional displacement of the shell 10 by the hook block 211.

[0032] Preferably, in this embodiment, the end of the hook block 211 away from the connecting sleeve 213 is arranged to be inclined in a V shape, ensuring the stable rotation and pulling action of the hook block 211 on the shell 10, and the smooth disengagement action after directional adjustment. In addition, the automatic resetting of the hook block 211 after rotation can be achieved by a torsion spring.

[0033] The magnetic sheet conveying mechanism 4 also includes: at least two guide track grooves 40, one end of each of the guide track grooves 40 is connected to a feed port 41, and the other end is opposite and spaced apart; a stop block 42, which is arranged at the end of the guide track groove 40 away from the feed port 41, and the stop block 42 can limit the movement of the magnetic sheet 11, so that the distance between the two magnetic sheets 11 is equal to the distance between the two magnetic suction blocks 51; a lifting cylinder 43, which is arranged above the guide track groove 40, and the output end of the lifting cylinder 43 is connected to a right-angle hook block 430, and the right-angle hook block 430 is used to drive the magnetic sheet 11 to rotate, so that the arc-shaped opening on the magnetic sheet 11 is vertically facing upward.

[0034] like Figure 6 As shown, the present embodiment is provided with two guide track grooves 40 with two outlet ends facing each other and placed at intervals. When a plurality of magnetic sheets 11 enter the guide track groove 40 from the feed port 41 in turn, the design of the guide track groove 40 ensures that the magnetic sheets 11 can move smoothly along the track groove. It is worth noting that the magnetic sheets 11 in the present embodiment are arranged in an arc shape. To ensure that an approximate circle can be formed when the two magnetic sheets 11 approach each other, during the conveying process of the magnetic sheets 11, the lifting cylinder 43 drives the right-angle hook block 430 to approach the guide track groove 40. If the arc-shaped opening of the magnetic sheet 11 faces the bottom wall of the guide track groove 40, the right-angle hook block 430 can extend between the magnetic sheet 11 and the guide track groove 40. As the lifting cylinder 43 drives the right-angle hook By moving block 430 upward, the magnetic sheet 11 can be flipped to 180 degrees (that is, the arc-shaped opening of the magnetic sheet 11 is vertically facing upward). It should be added that the flipping of the magnetic sheet 11 can also be achieved by using the same structure of the above-mentioned flip motor 32 and flip block 320, which will not be described in detail here. When the magnetic sheet 11 is in a vertical position and transferred to the position of the stop block 42, the stop block 42 prevents the magnetic sheet 11 from continuing to move forward. Through the limiting effect of the stop block 42, it is ensured that the distance between the two magnetic sheets 11 is equal to the distance between the two magnetic blocks 51, so that when the magnetic block 51 extends between the two magnetic sheets 11, it can be stably adsorbed on both sides of the magnetic pressure block 50, thereby providing a guarantee for the accuracy and stability during subsequent assembly.

[0035] The first assembly mechanism 5 also includes: a mounting platform 52; a horizontal moving cylinder 53, which is arranged on the mounting platform 52, and the output end of the horizontal moving cylinder 53 is connected to a moving seat 54, and a snap-fit ​​block 540 is formed at the bottom of the moving seat 54, and a snap-fit ​​groove 520 is provided on the mounting platform 52, and the snap-fit ​​block 540 is movably snap-fitted in the snap-fit ​​groove 520; a vertical moving cylinder 55, which is connected to the moving seat 54, and the output end of the vertical moving cylinder 55 is connected to the magnetic pressure block 50 and the magnetic attraction block 51.

[0036] like Figure 2 and Figure 7 As shown, when the two magnetic sheets 11 are pressed against the stop block 42 in a vertical posture, the vertical moving cylinder 55 can be driven by the horizontal moving cylinder 53 to move to the top of the magnetic sheet 11. During this process, the design of the engaging block 540 and the engaging groove 520 makes the horizontal movement of the moving seat 54 more stable and smooth, ensuring that the magnetic pressing block 50 and the magnetic suction block 51 can be accurately positioned above the magnetic sheet 11, thereby improving the assembly accuracy; as the vertical moving cylinder 55 drives the magnetic pressing block 50 and the magnetic suction block 51 to descend, the magnetic sheet 11 is adsorbed by the magnetic suction block 51, and the magnetic sheet 11 is pressed against the two sides of the magnetic pressing block 50. It should be added that Figure 7 As shown, the magnetic pressing block 50 in this embodiment is overall T-shaped, and the magnetic block 51 is located in the vertical position of the magnetic pressing block 50. As the horizontal moving cylinder 53 drives the vertical moving cylinder 55 to move to the top of the shell 10, the vertical position of the magnetic pressing block 50 can be inserted into the shell 10 by driving the vertical moving cylinder 55 (which means that the magnetic sheets 11 on both sides are synchronously extended into the shell 10). After the magnetic sheets 11 are fully inserted into the inner wall of the shell 10, the magnetic block 51 loses its magnetism and rises to separate from the magnetic sheets 11, thereby completing the assembly of the semi-finished product. The entire assembly process is highly automated. The combined use of the horizontal moving cylinder 53 and the vertical moving cylinder 55 enables the magnetic pressing block 50 and the magnetic block 51 to be flexibly moved in both horizontal and vertical directions, thereby meeting the complex movement requirements during the assembly process, reducing the need for manual operation, and improving production efficiency.

[0037] The second assembly mechanism 7 also includes: a mounting frame 71; a pushing cylinder 72, which is arranged on one side of the outlet end of the vibration plate 6, and the output end of the pushing cylinder 72 is connected to a receiving block 720, and the receiving block 720 is used to support the pin 12 and push it to move against the profiling block 70; an assembly cylinder 73, which is arranged on the mounting frame 71 in the vertical direction, and the output end of the assembly cylinder 73 is connected to the profiling block 70, so as to drive the profiling block 70 in the magnetized state to move into the shell 10.

[0038] like Figure 2 and Fig. 9As shown, when the above-mentioned semi-finished product is assembled and transferred to the bottom of the assembly cylinder 73, several pins 12 in the vibration plate 6 are also transported to the receiving block 720 one by one in turn. The design of the receiving block 720 ensures that the pins 12 can be accurately supported and positioned, providing an accurate position for subsequent assembly. It should be noted that after the vibration feeding and guiding of the vibration plate 6, the pins 12 in the receiving block 720 are placed vertically (the pins 12 can be guided by the inclined design, which is not shown in the figure). As the pushing cylinder 72 pushes the receiving block 720 and the pins 12 thereon, the pins 12 are moved against the profiling block 70, thereby reducing the shaking or deviation of the pins 12 during the pushing process. At this time, the profiling block 70 switches to the magnetized state to adsorb the pin 12. When the assembly cylinder 73 pushes the pin 12 to be completely inserted into the shell 10, the profiling block 70 switches to the demagnetized state. The flanges 120 at both ends of the pin 12 elastically reset after losing the magnetic force, thereby moving the magnetic sheet 11 against the positioning block 100 (i.e., assembling into the required finished product). At the same time, the assembly cylinder 73 can also drive the profiling block 70 to smoothly detach from the outside of the shell 10. This structure ensures that the pin 12 can be firmly adsorbed through the state switching of the profiling block 70, prevents it from falling off or deflecting during the insertion process of the shell 10, improves the reliability of assembly, and ensures that the quality of the assembled finished product can meet the user's usage requirements.

[0039] The feeding mechanism 8 includes: a base plate 80, on which a sliding seat 81 is arranged; a positioning seat 82 and an adjusting seat 83, both of which are L-shaped, are arranged on the base plate 80, and the positioning seat 82 and the adjusting seat 83 jointly form a placement groove; a clamping assembly 84, which is movably arranged on the sliding seat 81, and the clamping assembly 84 is provided with a first clamping block 840 and a second clamping block 841, and the first clamping block 840 and the second clamping block 841 can be clamped on the outer wall of the shell 10 when they are rotated towards each other and approached; a plurality of adjusting cylinders 85, which are arranged on the base plate 80, and the sliding seat 81 and the adjusting seat 83 are respectively connected to the output end of the adjusting cylinder 85; a material moving cylinder 86, which is arranged on the base plate 80, and the output end of the material moving cylinder 86 is connected to the clamping assembly 84.

[0040] like Figure 2 and Fig.10As shown, when the conveyor belt 30 pushes the adjusted housing 10 into the placement groove between the positioning seat 82 and the adjustment seat 83, the first clamping block 840 and the second clamping block 841 clamp the outer wall of the housing 10 when rotating towards each other, ensuring that the housing 10 will not shake during the assembly process of the magnetic sheet 11 and the pin 12. At the same time, the material transfer cylinder 86 drives the clamping assembly 84 to move, so that the housing 10 can be moved to the bottom of the magnetic suction block 51 and the profiling block 70 in turn to complete the corresponding assembly operation. It should be noted that for different housings 10 signal, in this embodiment, the adjusting cylinder 85 can be used to drive the adjusting seat 83 to move closer to or farther away from the positioning seat 82, thereby ensuring that the gap size of the placement groove can be adapted to different types of shells 10, thereby increasing the application range of the assembly equipment and improving the flexibility during assembly. In the process of adjusting the size of the placement groove, the position of the clamping assembly 84 must be changed synchronously, and the corresponding adjustment function can be completed simultaneously under the cooperation of the adjusting cylinder 85 and the sliding seat 81 (which has the same moving direction as the adjusting cylinder 85 and the adjusting seat 83).

[0041] The clamping assembly 84 includes: a moving block 842, which is movably arranged on the sliding seat 81, and the output end of the material transfer cylinder 86 is connected to the moving block 842, and the moving block 842 is also provided with a fixed seat 842a; a moving rod 843, on which a plurality of extension blocks 844 movably arranged in the fixed seat 842a are evenly distributed, and each extension block 844 is arranged in an array with a plurality of convex teeth 844a; a first rotating shaft 845 and a second rotating shaft 846 are arranged in the fixed seat 842a and are respectively located at On both sides of the extension block 844, the first clamping block 840 is connected to the first rotating shaft 845, the second clamping block 841 is connected to the second rotating shaft 846, and gears 847 are connected to the first rotating shaft 845 and the second rotating shaft 846, and the convex tooth 844a is movably engaged with the gear 847; the clamping cylinder 848 is arranged on the sliding seat 81, and the output end of the clamping cylinder 848 is connected to the moving rod 843, so that the extension block 844 can drive the gear 847 to rotate when making a linear motion.

[0042] Specifically, Fig.10As shown, when the shell 10 is located in the placement groove, the clamping cylinder 848 can push the moving rod 843 to move in advance. When the extension block 844 makes a linear motion along its length direction, the protruding teeth 844a on the extension block 844 and the gears 847 on both sides thereof can be movably engaged, so that the first rotating shaft 845 and the second rotating shaft 846 rotate synchronously, thereby driving the first clamping block 340 and the second clamping block 340 to rotate toward each other from the original open state and approach and press against the outer wall of the shell 10, and finally fix the shell 10; with the above-mentioned magnetic After the sheet 11 is inserted into the shell 10 through the magnetic block 51, the clamping cylinder 848 is still in a state of clamping the shell 10. It is worth noting that the moving directions of the output ends of the material transfer cylinder 86 and the clamping cylinder 848 in this embodiment are exactly opposite. Therefore, under the drive of the material transfer cylinder 86, the moving block 842 can be driven to move relatively on the sliding seat 81, and then the shell 10 is transferred to the next assembly process. Similarly, this structure can also be directly pushed to the outside of the equipment through the material transfer cylinder 86 after the finished product is assembled to complete the unloading function.

[0043] Preferably, for the movement of the sliding seat 81 relative to the base plate 80 and the displacement of the moving block 842 relative to the sliding seat 81, the cooperation of the slider and the slide rail can be adopted to ensure the smoothness and stability of the overall operation.

[0044] It should be noted that, during the assembly process, the detection of the positions of components can be performed by using position sensors, laser sensors and other detection devices to complete the corresponding detection functions.

[0045] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).
