Technical Field

[0001] The invention relates to the technical field of assembly, in particular to an assembly device with a positioning function for an inhaler. Background Art

[0002] In pharmaceutical equipment, various inhalers are important methods of drug delivery. Inhalers can be used to inhale liquid drugs into containers or respiratory tracts, thereby achieving drug supply. Inhalers mainly include inhalation devices, shells and nozzles. The degree of assembly coordination of these three directly determines the use effect of the inhaler, especially the assembly accuracy of the nozzle determines the accuracy and safety of the inhaled medicine. In addition, in order to conform to ergonomics, the nozzle generally adopts an elliptical structure, and the elliptical nozzle is difficult to position in the mounting hole during assembly.

[0003] Furthermore, when assembling the inhaler, the nozzle needs to pass through the shell through the through hole for assembly, which makes it difficult to position and adjust the nozzle during assembly. It needs to be positioned in advance and then installed, which has certain requirements for assembly accuracy. However, currently, inhaler product assembly is generally done manually, which is time-consuming, has low production quality and unsatisfactory production efficiency. Summary of the invention

[0004] The object of the present invention is to provide an assembly device for an inhaler with a positioning function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: The present invention provides a technical solution of an assembly device for an inhaler with a positioning function, the inhaler includes a shell and a nozzle, the assembly device includes a frame, a conveying device, a vibration disk, a clamping mechanism and a positioning mechanism, the conveying device is tightly connected to the frame, the conveying device is used to convey the shell of the inhaler, the vibration disk is tightly connected to the frame, the discharge port of the vibration disk is provided with a feeding hose, the feeding hose is connected to the positioning mechanism, the clamping mechanism is tightly connected to the frame, the positioning mechanism is tightly connected to the frame, and the positioning mechanism is used to insert the nozzle of the inhaler into the shell.

[0006] The assembly device of the present invention is used to install the suction nozzle of the inhaler into the mounting hole of the shell. The cross-section of the suction nozzle is elliptical. The frame is used to provide stable support for each mechanism. During the assembly operation, the conveying device conveys the shell to the position of the clamping mechanism in sequence. The clamping mechanism can clamp the shell. The suction nozzle to be assembled is placed in the vibration plate. The suction nozzle is automatically and orderly arranged in a directional manner through vibration, and is accurately conveyed to the positioning mechanism through a feeding hose. The positioning mechanism adjusts the position of the suction nozzle that falls into it so that the position of the suction nozzle corresponds to the mounting hole on the shell, thereby accurately assembling the suction nozzle into the shell.

[0007] The positioning mechanism comprises a connecting component, a guiding component, a movable component and an opening and closing component. The connecting component is tightly connected to the frame, the guiding component is tightly connected to the connecting component, the movable component is tightly connected to the guiding component, and the opening and closing component is tightly connected to the connecting component.

[0008] The connecting component is used to connect the positioning mechanism and the frame together, the guide component guides the movement path of the suction nozzle, the movable component is used to drive the suction nozzle to move so that the suction nozzle is assembled into the shell, and the opening and closing component is used to control the opening and closing of the guide component, that is, to control the suction nozzle to be assembled into the corresponding shell in sequence.

[0009] The connecting assembly comprises a supporting frame and a telescopic cylinder, the telescopic cylinder is tightly connected to the frame, the output end of the telescopic cylinder is tightly connected to the supporting frame, and the supporting frame is tightly connected to the guiding assembly.

[0010] The telescopic cylinder is fixed on the frame and is used to drive the support frame to move up and down, thereby driving the guide assembly to move up and down, so that the movable assembly can be close to the shell on the conveying device, so as to facilitate the installation of the suction nozzle positioned by the movable assembly into the shell.

[0011] The guide assembly comprises a fixed ring, a rotating ring and a guide cylinder. The fixed ring is tightly connected to the support frame. The rotating ring is provided with a slide groove, which is rotatably connected to the fixed ring. The guide cylinder is tightly connected to the rotating ring.

[0012] The fixed ring is fixed on the support frame to provide support for the guide assembly. The fixed ring is connected to the feed hose. The suction nozzle transported by the vibration plate passes through the fixed ring, the rotating ring and the guide cylinder in turn, and finally falls into the opening and closing assembly to facilitate the subsequent movable assembly to position the suction nozzle. The rotating ring can rotate relative to the fixed ring along the slide groove, thereby driving the guide cylinder to rotate, so as to adjust the position of the suction nozzle entering the guide cylinder to correspond to the position of the mounting hole of the shell on the conveying device.

[0013] The movable component includes a rotating motor, a transmission gear, a movable ring, an adjusting push rod, a clamping push rod and a positioning clamp. The rotating motor is tightly connected to the fixed ring, the output end of the rotating motor is transmission-connected to the transmission gear, a tooth surface is provided on the side wall of the rotating ring, the transmission gear is meshed with the tooth surface, the adjusting push rod is tightly connected to the rotating ring, the output end of the adjusting push rod is transmission-connected to the movable ring, the diameter of the movable ring is larger than the diameter of the guide cylinder, the clamping push rod is tightly connected to the movable ring, the clamping push rods are symmetrically arranged on both sides of the movable ring, the output end of the clamping push rod is transmission-connected to the positioning clamp, and guide grooves are provided on both sides of the guide cylinder.

[0014] After the suction nozzle falls into the guide cylinder, the positioning claws located on both sides of the guide cylinder are driven by the clamping push rod, and the movable ring is used to provide an installation basis for the clamping push rod, and move toward the inside of the guide cylinder, and the positioning claws are V-shaped, so that under the positioning action of the V-shaped positioning claws, the elliptical suction nozzle will be fixed in the center of the guide cylinder, and the center of the guide cylinder corresponds to the center of the mounting hole on the shell fixed by the clamping mechanism, that is, the effect of fitting the center of the suction nozzle with the center of the mounting hole on the shell is achieved, the position of the suction nozzle is positioned, and thus the installation accuracy is improved; the suction nozzle positioned by the positioning claws moves downward driven by the adjusting push rod, Insert the mounting hole on the shell to complete the assembly, and the guide grooves on both sides of the guide cylinder are used to provide space for the up and down movement of the positioning clamp; however, the position of the suction nozzle falling into the guide cylinder is uncertain, and the positioning clamp can only locate the center of the suction nozzle, but cannot locate the angle position of the suction nozzle. There are two situations in which the positioning clamp clamps the suction nozzle, one is to clamp it to the long axis end of the elliptical suction nozzle, and the other is to clamp it to the short axis end of the elliptical suction nozzle, and the position of the shell fixed by the clamping mechanism on the conveying device is fixed. If the angle of the suction nozzle does not correspond to the mounting hole on the shell, you only need to start the rotating motor to drive the rotating ring to rotate ninety degrees to make the angle of the suction nozzle correspond to the mounting hole on the shell.

[0015] An air bag is provided at one end of the positioning clamp close to the suction nozzle, an active cavity and a detection cavity are provided in the positioning clamp, the active cavity and the detection cavity are connected with the air bag, a detection component is provided in the active cavity, the detection component includes a piston, a repelling magnet and a varistor, the piston is slidably connected to the active cavity, the repelling magnet is slidably connected to the detection cavity, one end of the varistor is firmly connected to the inner wall of the detection cavity, the other end of the varistor is in contact with the repelling magnet, an iron core is provided on the piston, a coil is wound on the active cavity, the coil is externally connected to a power supply, the varistor is externally connected to a detection power supply, the detection power supply and the varistor form a detection system, and the detection system is electrically connected to the rotating motor;

[0016] During positioning: the iron core is inserted into the coil to form an electromagnet, and the facing ends of the electromagnet and the repelling magnet are the same magnetic poles.

[0017] When positioning the nozzle, when the positioning jaws are clamped to the long axis end of the elliptical nozzle, the volume of the nozzle compression airbag is larger, that is, the distance the piston is pushed by the airbag in the active cavity is longer, and the distance the iron core is inserted into the coil is longer. The magnetic force of the electromagnet composed of the two is larger, the repulsive force on the repulsive magnet is greater, and the pressure on the varistor is greater. Suppose the resistance value of the varistor detected by the detection system at this time is R; when the positioning jaws are clamped to the short axis end of the elliptical nozzle, the volume of the nozzle compression airbag is smaller, that is, the distance the piston is pushed by the airbag in the active cavity is shorter, and the distance the iron core is inserted into the coil is shorter. The magnetic force of the electromagnet composed of the two is smaller, and the repulsive force on the repulsive magnet is smaller. The smaller it is, the smaller the pressure on the varistor. Suppose the detection system detects that the resistance of the varistor is R at this time; and the resistance of the varistor decreases with the increase of the pressure, that is, R is less than R. By judging the resistance of the varistor through the detection system, it can be determined whether the positioning claw is clamped to the short axis end or the long axis end of the elliptical nozzle. If the angle of the nozzle does not correspond to the mounting hole on the shell, the detection system only needs to control the rotating motor to drive the rotating ring to rotate 90 degrees to make the angle of the nozzle correspond to the mounting hole on the shell. In other words, automatic adjustment is realized according to the angle position of the nozzle, so that the nozzle and the mounting hole position on the shell below are corresponding, which further improves the installation accuracy.

[0018] The opening and closing assembly includes a fixed frame, an opening and closing push rod and a baffle. The fixed frame is tightly connected to the support frame, the opening and closing push rod is tightly connected to the fixed frame, the output end of the opening and closing push rod is transmission-connected to the baffle, and the baffle is slidingly connected to the bottom end of the guide cylinder.

[0019] The fixing frame is fixed on the supporting frame as the installation basis of the opening and closing assembly. The opening and closing assembly is used to control the opening and closing of the guide cylinder outlet. When performing the positioning operation, the baffle closes the guide cylinder outlet under the drive of the opening and closing push rod to prevent the suction nozzle from slipping out of the guide cylinder. After the positioning is completed, the baffle moves to both sides along the bottom end of the guide cylinder under the drive of the opening and closing push rod, thereby opening the guide cylinder outlet for subsequent assembly operations.

[0020] The conveying device includes an active roller, a driven roller, a driving motor and a conveyor belt. The rotating shafts of the active roller and the driven roller are rotatably connected to the frame, the driving motor is tightly connected to the frame, the output end of the driving motor is transmission-connected to the active roller, and the conveyor belt is sleeved on the active roller and the driven roller.

[0021] The drive motor is the main power source of the conveying device. The drive motor outputs torque to drive the active roller to rotate, thereby driving the conveyor belt installed on the active roller and the driven roller to move, thereby driving the shell placed on the conveyor belt to move toward the clamping mechanism in sequence.

[0022] The clamping mechanism comprises a clamping cylinder and a fixed clamping claw. The clamping cylinder is firmly connected to the frame and arranged on both sides of the conveyor belt. The output end of the clamping cylinder is drivingly connected to the fixed clamping claw.

[0023] The fixed clamping claw is arc-shaped and matches the outer contour of the shell, so that the shell driven by the conveyor belt to the clamping position can be positioned and clamped, so that the center of the shell fits with the center of the guide cylinder.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. After the suction nozzle falls into the guide cylinder, the positioning claws on both sides of the guide cylinder are driven by the clamping push rod, and the movable ring is used to provide an installation basis for the clamping push rod, and move toward the inside of the guide cylinder, and the positioning claws are V-shaped. In this way, under the positioning effect of the V-shaped positioning claws, the elliptical suction nozzle will be fixed in the center of the guide cylinder, and the center of the guide cylinder corresponds to the center of the mounting hole on the shell fixed by the clamping mechanism, that is, the center of the suction nozzle is matched with the center of the mounting hole on the shell, and the position of the suction nozzle is positioned, thereby improving the installation accuracy;

[0026] 2. When the positioning jaws are clamping the elliptical nozzle, the volume of the compressed airbag at the long axis end of the elliptical nozzle is greater than the volume of the compressed airbag at the short axis end. Through the combination of the piston, the iron core and the coil, the change in the volume of the airbag is quantified as the change in the resistance value of the varistor, thereby automatically judging whether the positioning jaws are clamped to the short axis end or the long axis end of the elliptical nozzle. Then, the detection system controls the rotating motor to drive the rotating ring to rotate ninety degrees to make the angle of the nozzle correspond to the mounting hole on the outer shell. In other words, automatic adjustment is achieved according to the angle position of the nozzle, so that the nozzle corresponds to the mounting hole position on the outer shell below, further improving the assembly accuracy.

[0039] The assembling device of the present invention is used to install the suction nozzle 7 of the inhaler into the mounting hole of the shell 6. The cross-section of the suction nozzle 7 is elliptical. The frame 1 is used to provide stable support for each mechanism. During the assembly operation, the conveying device 2 conveys the shell 6 to the position of the clamping mechanism 4 in sequence. The clamping mechanism 4 can clamp the shell 6. The suction nozzle 7 to be assembled is placed in the vibration plate 3. The suction nozzle 7 is automatically and orderly arranged in a directional manner through vibration, and is accurately conveyed to the positioning mechanism 5 through the feeding hose 31. The positioning mechanism 5 adjusts the position of the suction nozzle 7 falling therein so that the position of the suction nozzle 7 corresponds to the mounting hole on the shell 6, thereby accurately assembling the suction nozzle 7 into the shell 6.

[0040] The positioning mechanism 5 includes a connecting component 51, a guiding component 52, a movable component 53 and an opening and closing component 54. The connecting component 51 is tightly connected to the frame 1, the guiding component 52 is tightly connected to the connecting component 51, the movable component 53 is tightly connected to the guiding component 52, and the opening and closing component 54 is tightly connected to the connecting component 51.

[0041] The connecting component 51 is used to connect the positioning mechanism 5 and the frame 1 together, the guide component 52 guides the movement path of the suction nozzle 7, the movable component 53 is used to drive the suction nozzle 7 to move so that the suction nozzle 7 is assembled into the outer shell 6, and the opening and closing component 54 is used to control the opening and closing of the guide component 52, that is, to control the suction nozzle 7 to be assembled into the corresponding outer shell 6 in sequence.

The output end of the telescopic cylinder 512 is tightly connected to the supporting frame 511 . The supporting frame 511 is tightly connected to the guiding assembly 52 .

[0043] The telescopic cylinder 512 is fixed on the frame 1, and is used to drive the support frame 511 to move up and down, thereby driving the guide assembly 52 to move up and down, so that the movable assembly 53 can be close to the shell 6 on the conveying device 2, so as to facilitate the installation of the suction nozzle 7 positioned by the movable assembly 53 into the shell 6.

[0044] The guide assembly 52 includes a fixed ring 521 , a rotating ring 522 and a guide cylinder 523 . The fixed ring 521 is tightly connected to the support frame 511 . The rotating ring 522 is provided with a slide groove 5221 , which is rotatably connected to the fixed ring 521 . The guide cylinder 523 is tightly connected to the rotating ring 522 .

[0045] The fixed ring 521 is fixed on the support frame 511 to provide support for the guide assembly 52. ​​The fixed ring 521 is connected to the feed hose 31. The suction nozzle 7 transported through the vibration plate 3 passes through the fixed ring 521, the rotating ring 522 and the guide cylinder 523 in sequence, and finally falls into the opening and closing assembly 54, so that the subsequent movable assembly 53 can position the suction nozzle 7. The rotating ring 522 can rotate relative to the fixed ring 521 along the slide groove 5221, thereby driving the guide cylinder 523 to rotate, so as to adjust the position of the suction nozzle 7 entering the guide cylinder 523 so that it corresponds to the position of the mounting hole of the shell 6 on the conveying device 2.

[0046] The movable assembly 53 includes a rotating motor 531, a transmission gear 532, a movable ring 533, an adjusting push rod 534, a clamping push rod 535 and a positioning clamp 536. The rotating motor 531 is tightly connected to the fixed ring 521, and the output end of the rotating motor 531 is transmission-connected to the transmission gear 532. A tooth surface 5222 is provided on the side wall of the rotating ring 522, and the transmission gear 532 meshes with the tooth surface 5222. The adjusting push rod 534 is tightly connected to the rotating ring 522, and the output end of the adjusting push rod 534 is transmission-connected to the movable ring 533. The diameter of the movable ring 533 is larger than the diameter of the guide cylinder 523. The clamping push rod 535 is tightly connected to the movable ring 533, and the clamping push rods 535 are symmetrically arranged on both sides of the movable ring 533. The output end of the clamping push rod 535 is transmission-connected to the positioning clamp 536, and guide grooves 5231 are provided on both sides of the guide cylinder 523.

[0047] After the suction nozzle 7 falls into the guide cylinder 523, the positioning claws 536 located on both sides of the guide cylinder 523 are driven by the clamping push rod 535. The movable ring 533 is used to provide a mounting base for the clamping push rod 535 and moves toward the inside of the guide cylinder 523, and the positioning claws 536 are V-shaped. In this way, under the positioning effect of the V-shaped positioning claws 536, the elliptical suction nozzle 7 will be fixed in the center of the guide cylinder 523, and the center of the guide cylinder 523 corresponds to the center of the mounting hole on the shell 6 fixed by the clamping mechanism 4, that is, the effect of fitting the center of the suction nozzle 7 with the center of the mounting hole on the shell 6 is achieved, the position of the suction nozzle 7 is positioned, and thus the installation accuracy is improved; after being positioned by the positioning claws 536, the suction nozzle 7 is driven by the adjusting push rod 534 to move toward The guide grooves 5231 on both sides of the guide cylinder 523 are used to provide space for the upward and downward movement of the positioning jaws 536; however, the position of the suction nozzle 7 falling into the guide cylinder 523 is uncertain, and the positioning jaws 536 can only locate the center of the suction nozzle 7, and cannot locate the angular position of the suction nozzle 7. There are two situations in which the positioning jaws 536 clamp the suction nozzle 7, one is clamped to the long axis end of the elliptical suction nozzle 7, and the other is clamped to the short axis end of the elliptical suction nozzle 7. The position of the housing 6 fixed by the clamping mechanism 4 on the conveying device 2 is fixed. If the angle of the suction nozzle 7 does not correspond to the mounting hole on the housing 6, it is only necessary to start the rotating motor 531 to drive the rotating ring 522 to rotate ninety degrees to make the angle of the suction nozzle 7 correspond to the mounting hole on the housing 6.

[0048] An airbag 537 is provided at one end of the positioning clamp 536 close to the suction nozzle 7, and an active chamber 5361 and a detection chamber 5362 are provided in the positioning clamp 536, and the active chamber 5361 and the detection chamber 5362 are communicated with the airbag 537. A detection component 55 is provided in the active chamber 5361, and the detection component 55 includes a piston 551, a repelling magnet 552 and a varistor 553. The piston 551 is slidably connected to the active chamber 5361, the repelling magnet 552 is slidably connected to the detection chamber 5362, one end of the varistor 553 is tightly connected to the inner wall of the detection chamber 5362, and the other end of the varistor 553 abuts against the repelling magnet 552. An iron core 554 is provided on the piston 551, and a coil 555 is wound on the active chamber 5361. The coil 555 is externally connected to a power supply, and the varistor 553 is externally connected to a detection power supply. The detection power supply and the varistor 553 form a detection system, and the detection system is electrically connected to the rotating motor 531;

[0049] During positioning: the iron core 554 is inserted into the coil 555 to form an electromagnet, and the facing ends of the electromagnet and the repelling magnet 552 are the same magnetic poles.

[0050] When positioning the suction nozzle 7, when the positioning clamp 536 is clamped to the long axis end of the elliptical suction nozzle 7, the volume of the airbag 537 compressed by the suction nozzle 7 is larger, that is, the distance that the piston 551 is pushed by the airbag 537 in the active chamber 5361 is longer, and the distance that the iron core 554 is inserted into the coil 555 is longer. The electromagnetic force composed of the two is larger, the repulsive force on the repulsive magnet 552 is greater, and the pressure on the varistor 553 is greater. Suppose at this time the detection system detects that the resistance of the varistor 553 is R1; when the positioning clamp 536 is clamped to the short axis end of the elliptical suction nozzle 7, the volume of the airbag 537 compressed by the suction nozzle 7 is smaller, that is, the distance that the piston 551 is pushed by the airbag 537 in the active chamber 5361 is shorter, and the distance that the iron core 554 is inserted into the coil 555 is shorter. The electromagnetic force composed of the two is larger. The smaller the ferromagnetic force is, the smaller the repulsive force on the repulsive magnet 552 is, and the smaller the pressure on the varistor 553 is. Suppose at this time the detection system detects that the resistance of the varistor 553 is R2; and the resistance of the varistor decreases with the increase of the pressure, that is, R1 is less than R2. By judging the resistance of the varistor 553 by the detection system, it can be judged whether the positioning claw 536 is clamped to the short axis end or the long axis end of the elliptical suction nozzle 7. If the angle of the suction nozzle 7 does not correspond to the mounting hole on the outer shell 6, the detection system only needs to control the rotating motor 531 to drive the rotating ring 522 to rotate ninety degrees to make the angle of the suction nozzle 7 correspond to the mounting hole on the outer shell 6, that is, to realize automatic adjustment according to the angle position of the suction nozzle 7, so that the suction nozzle 7 corresponds to the mounting hole position on the lower outer shell 6, thereby further improving the installation accuracy.

[0051] The opening and closing assembly 54 includes a fixed frame 541, an opening and closing push rod 542 and a baffle 543. The fixed frame 541 is fastened to the support frame 511, the opening and closing push rod 542 is fastened to the fixed frame 541, the output end of the opening and closing push rod 542 is transmission-connected to the baffle 543, and the baffle 543 is slidingly connected to the bottom end of the guide cylinder 523.

[0052] The fixing frame 541 is fixed on the supporting frame 511 as the installation base of the opening and closing component 54. The opening and closing component 54 is used to control the opening and closing of the outlet of the guide cylinder 523. When performing the positioning operation, the baffle 543 closes the outlet of the guide cylinder 523 under the drive of the opening and closing push rod 542 to prevent the suction nozzle 7 from slipping out of the guide cylinder 523. After the positioning is completed, the baffle 543 moves to both sides along the bottom end of the guide cylinder 523 under the drive of the opening and closing push rod 542, thereby opening the outlet of the guide cylinder 523 to facilitate the subsequent assembly operation.

[0053] The conveying device 2 includes an active roller 21, a driven roller 22, a driving motor 23 and a conveyor belt 24. The rotating shafts of the active roller 21 and the driven roller 22 are rotatably connected to the frame 1, the driving motor 23 is tightly connected to the frame 1, the output end of the driving motor 23 is transmission-connected to the active roller 21, and the conveyor belt 24 is sleeved on the active roller 21 and the driven roller 22.

[0054] The driving motor 23 is the main power source of the conveying device 2. The driving motor 23 outputs torque to drive the active roller 21 to rotate, thereby driving the conveyor belt 24 installed on the active roller 21 and the driven roller 22 to move, thereby driving the shell 6 placed on the conveyor belt 24 to move toward the clamping mechanism 4 in sequence.

[0055] The clamping mechanism 4 includes a clamping cylinder 41 and a fixed clamping claw 42 . The clamping cylinder 41 is tightly connected to the frame 1 . The clamping cylinder 41 is arranged on both sides of the conveyor belt 24 . The output end of the clamping cylinder 41 is drivingly connected to the fixed clamping claw 42 .

[0056] The fixed clamping claw 42 is arc-shaped and matches the outer contour of the shell 6 , so that the shell 6 driven by the conveyor belt 24 to the clamping position can be positioned and clamped, so that the center of the shell 6 fits with the center of the guide cylinder 523 .

[0057] The working principle of the present invention is as follows: when positioning the suction nozzle 7, when the positioning clamp 536 is clamped to the long axis end of the elliptical suction nozzle 7, because the curvature of the long axis end is small, the volume of the airbag 537 compressed by the suction nozzle 7 is small, that is, the distance that the piston 551 is pushed by the airbag 537 in the active chamber 5361 is short, and the distance that the iron core 554 is inserted into the coil 555 is shorter, the magnetic force of the electromagnet composed of the two is small, the repulsive force on the repulsive magnet 552 is smaller, and the pressure on the varistor 553 is smaller. It is assumed that the resistance value of the varistor 553 detected by the detection system at this time is R1; when the positioning clamp 536 is clamped to the short axis end of the elliptical suction nozzle 7, because the curvature of the short axis end is large, the volume of the airbag 537 compressed by the suction nozzle 7 is large, that is, the distance that the piston 551 is pushed by the airbag 537 in the active chamber 5361 is long, and the iron core 554 is inserted into the coil 555 The longer the distance inside, the greater the magnetic force of the electromagnet formed by the two, the greater the repulsive force on the repulsive magnet 552, and the greater the pressure on the varistor 553. Suppose at this time the detection system detects that the resistance of the varistor 553 is R2; and the resistance of the varistor decreases with the increase of the pressure, that is, R1 is greater than R2. By judging the resistance of the varistor 553 through the detection system, it can be judged whether the positioning clamp 536 is clamped to the short axis end or the long axis end of the elliptical suction nozzle 7. If the angle of the suction nozzle 7 does not correspond to the mounting hole on the shell 6, the detection system only needs to control the rotating motor 531 to drive the rotating ring 522 to rotate ninety degrees to make the angle of the suction nozzle 7 correspond to the mounting hole on the shell 6, that is, to realize automatic adjustment according to the angle position of the suction nozzle 7, so that the suction nozzle 7 corresponds to the mounting hole position on the lower shell 6, thereby further improving the installation accuracy.
