Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of battery formation, and particularly relates to a suction nozzle pulling tool and a battery formation device. BACKGROUND

[0002] In a battery formation process of a lithium battery back-end production line, a rubber suction nozzle on a negative pressure cup in a battery formation device is usually used to seal a liquid injection port of a battery, so that bubbles in the battery can be drawn away by negative pressure. Since the rubber suction nozzle is often in contact with electrolyte, it is easy to crystallize and belongs to a consumable part, which needs to be replaced regularly. At present, a suction nozzle pulling tool is usually used to pull the suction nozzle from the negative pressure cup to replace the suction nozzle regularly.

[0003] Since the suction nozzles of the negative pressure cups corresponding to the liquid injection ports of a plurality of single batteries in a horizontal blade battery formation device are arranged in a transverse direction of the battery formation device, and most of the existing suction nozzle pulling tools are designed for square batteries (i.e., the suction nozzles of the negative pressure cups in a square battery formation device are arranged in a longitudinal direction of the battery formation device), the existing suction nozzle pulling tools cannot be applied to the pulling operation of the suction nozzles on the negative pressure cups of the horizontal blade battery formation device.

[0004] Therefore, the utility model is provided. TECHNICAL PROBLEM

[0005] The application provides a suction nozzle pulling tool and a battery formation device to solve the problem of pulling the suction nozzles on a horizontal blade battery formation device.

Each suction nozzle pulling unit includes two clamping assemblies arranged opposite in a vertical direction and used for clamping or releasing the suction nozzles on one side in a transverse direction, and a driving mechanism connected with at least one of the two clamping assemblies and used for driving the corresponding clamping assembly to act in the vertical direction, so that the two clamping assemblies can clamp or release the suction nozzles.

[0007] In an optional scheme of the application, each clamping assembly includes a clamping plate and a plurality of clamping claws arranged on the clamping plate in a longitudinal direction. The driving mechanism is connected with at least one of the two clamping plates and used for driving the corresponding clamping plate to act in the vertical direction, so that the two clamping claws arranged opposite in the vertical direction can clamp or release the suction nozzles.

[0008] In an optional scheme of the application, each clamping claw includes a connecting arm connected with the clamping plate, a clamping arm protruding from the connecting arm in the vertical direction, and a plurality of clamping protrusions arranged in the transverse direction and each protruding from the clamping arm in the vertical direction.

[0010] In an optional solution of the present application, the driving mechanism further comprises a second rack connected with the other clamping plate and engaged with the gear. The second rack is arranged on the two sides of the gear in the longitudinal direction respectively, and can move towards or away from each other in the vertical direction under the action of the rotation of the gear.

[0011] In an optional solution of the present application, each suction nozzle unit further comprises a mounting plate arranged between the fixed frame and the clamping assembly in the transverse direction, and a resilient member arranged between the mounting plate and the fixed frame.

[0012] In an optional solution of the present application, each suction nozzle unit further comprises a connecting block fixedly arranged on the fixed frame, and an adjusting assembly having one end connected with the mounting plate and the other end connected with the connecting block, and the adjusting member is arranged to be movable relative to the connecting block to adjust the relative position of the mounting plate and the fixed frame in the vertical direction.

[0013] In an optional solution of the present application, the suction nozzle tool further comprises a base plate, and an electromagnet. The fixed frame is arranged on one end of the base plate in the transverse direction, and the electromagnet is arranged on the other end of the base plate in the transverse direction.

[0014] In an optional solution of the present application, the suction nozzle tool further comprises a collection box arranged below the two clamping assemblies for collecting the suction nozzles released by the two clamping assemblies.

[0015] In an optional solution of the present application, the suction nozzle tool further comprises a pair of photoelectric sensors arranged on the fixed frame in the longitudinal direction opposite to each other, for detecting whether the suction nozzle unit contains a suction nozzle.

[0016] According to another aspect of the present application, a battery formation device is provided, comprising a negative pressure cup, a press mechanism, and the above-mentioned suction nozzle tool. The negative pressure cup is provided with suction nozzles arranged in the transverse direction. The press mechanism is used to drive the negative pressure cup to move in the transverse direction, so that the suction nozzles on the negative pressure cup can be inserted between the clamping assemblies and removed from the negative pressure cup.

[0017] In summary, the suction nozzle tool and the battery formation device provided by the present application have at least the following beneficial effects:

And under the action of the driving mechanism, at least one of the two clamping assemblies can move towards or away from each other in the vertical direction, so as to provide or cancel the clamping force for the suction nozzle in the vertical direction, thereby clamping or releasing the suction nozzle in the vertical direction. Therefore, during the process of pulling out the suction nozzle, the suction nozzle tool of the application not only can adapt to the fixation of the corresponding suction nozzle of the horizontal blade battery, but also can fix the suction nozzle by clamping the suction nozzle through the two clamping assemblies, thereby improving the force between the clamping assembly and the suction nozzle, thereby improving the stability and pulling efficiency of the suction nozzle during the process of pulling out the suction nozzle, and further enabling the suction nozzle to be replaced in time.

[0034] In order to make the above and other characteristics and advantages of the present application clearer, the following further describes the present application with reference to the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explanation and are only exemplary but not limiting.

[0035] In addition, if the features limited by "first" and "second" are used for the purpose of description, it should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. The features limited by "first" and "second" can explicitly or implicitly include at least one of the limited features. If "multiple" is described, it generally means at least two, such as two, three, etc., unless otherwise specifically limited.

[0036] The battery formation equipment provided by the present application can be applied to a horizontal blade battery, which comprises a press bench mechanism, a plurality of negative pressure cups and a suction nozzle tooling. The plurality of negative pressure cups are arranged on the press bench mechanism and arranged in the longitudinal direction L3. Each negative pressure cup is provided with a suction nozzle A arranged in the lateral direction L2 (i.e. the opening of the suction nozzle A faces the lateral direction L2). The press bench mechanism is a device or mechanism with specific driving function, and the suction nozzle tooling is a device or mechanism with clamping function. The negative pressure cup is driven by the press bench mechanism to move in the lateral direction L2, so that the suction nozzle A on the negative pressure cup can be inserted into the suction nozzle tooling and the suction nozzle A can be pulled out from the negative pressure cup.

[0037] Exemplarily, the press mechanism can adopt cylinder driving. When the cylinder of the press mechanism is controlled to rotate forward, the press mechanism drives the negative pressure cup to move close to the suction nozzle tool along the transverse direction L2, so that the suction nozzle A on the negative pressure cup extends into the suction nozzle tool. After the suction nozzle tool clamps the suction nozzle A, the cylinder of the press mechanism is controlled to rotate reversely, the press mechanism drives the negative pressure cup to move away from the suction nozzle tool along the transverse direction L2, so as to pull out the suction nozzle A from the negative pressure cup.

[0038] Since the liquid injection port and the pole of the horizontal blade battery are arranged on the side of the battery, when the battery formation equipment of the application is used to form the horizontal blade battery, the suction nozzles A on the plurality of negative pressure cups can face the liquid injection port and the pole of the horizontal blade battery in the transverse direction L2, so as to adapt to the liquid injection port sealing of the plurality of single batteries in the horizontal blade battery.

[0039] In other words, when the horizontal blade battery is formed, the arrangement direction of the plurality of negative pressure cups is consistent with the arrangement direction of the plurality of single batteries in the horizontal blade battery, that is, the longitudinal direction L3 mentioned in the application; the opening direction of the suction nozzle A on each negative pressure cup is consistent with the opening direction of the liquid injection port of the single battery, that is, the transverse direction L2 mentioned in the application. Therefore, in the application, the arrangement direction of the plurality of negative pressure cups is defined as the longitudinal direction L3 of the battery formation equipment, the opening direction of the suction nozzle A on each negative pressure cup is defined as the transverse direction L2 of the battery formation equipment, and the direction perpendicular to the horizontal plane of the battery formation equipment is defined as the vertical direction L1 of the battery formation equipment, and L1, L2 and L3 are perpendicular to each other.

[0040] In summary, the battery formation equipment of the application not only can adapt to the formation of the horizontal blade battery, but also can fix the suction nozzle A by clamping the suction nozzle A with the suction nozzle tool, increase the contact area between the suction nozzle A and the suction nozzle tool, and improve the friction therebetween, thereby avoiding slipping between the suction nozzle A and the suction nozzle tool during the pulling process, thereby improving the stability and pulling efficiency during the pulling process. Meanwhile, the battery formation equipment of the application uses the press mechanism to provide power for the pulling process of the suction nozzle tool, so that the suction nozzle tool does not need to be additionally provided with a power mechanism, thereby simplifying the structure of the suction nozzle tool and making the structure of the battery formation equipment more compact, thereby improving the space utilization of the equipment.

[0041] Further, the battery formation equipment provided by the application further comprises a control module (such as an upper computer), which is connected to the press mechanism and the suction nozzle tool and can control the actions of the internal components of the press mechanism and the internal components of the suction nozzle tool.

[0042] Figure 1 a perspective view of the suction nozzle tool provided by the application from one angle, Figure 2 a perspective view of the suction nozzle tool provided by the application from another angle.

[0043] Referring to Figure 1 and Figure 2 The suction nozzle pulling tool 1000 provided by the embodiment of the present application comprises a fixing frame 200 and at least one suction nozzle pulling unit 100 mounted on the fixing frame 200. When the number of suction nozzle pulling units 100 is multiple, the multiple suction nozzle pulling units 100 are sequentially arranged on the same fixing frame 200 along the longitudinal direction L3.

[0044] Each suction nozzle pulling unit 100 comprises two clamping assemblies 10 and a driving mechanism 20. The two clamping assemblies 10 are oppositely arranged in the vertical direction L1 and located on the side of the suction nozzle A on the negative pressure cup (i.e. the side of the suction nozzle A corresponding to the horizontal blade battery) in the transverse direction L2, and the driving mechanism 20 is connected with at least one of the two clamping assemblies 10.

[0045] When the suction nozzle pulling tool 1000 needs to pull out the suction nozzle A from the negative pressure cup, the corresponding clamping assembly 10 needs to be driven by the driving mechanism 20 to act in the vertical direction L1 first, so that the distance between the two clamping assemblies 10 is greater than the outer diameter of the suction nozzle A, at this time the suction nozzle A can be inserted between the two clamping assemblies 10 through the press bed mechanism; after the suction nozzle A is inserted between the two clamping assemblies 10, the corresponding clamping assembly 10 is driven by the driving mechanism 20 to act in the vertical direction L1 again, so that the two clamping assemblies 10 clamp the suction nozzle A, at this time the suction nozzle A can be pulled out from the negative pressure cup through the press bed mechanism; and after the suction nozzle A is pulled out from the negative pressure cup, the corresponding clamping assembly 10 is driven by the driving mechanism 20 to act in the vertical direction L1 again, so that the two clamping assemblies 10 release the suction nozzle A, thereby realizing the clamping or releasing of the suction nozzle A by the suction nozzle pulling tool 1000 based on the cooperation of the clamping assembly 10 and the driving mechanism 20.

[0046] In order to adapt to the horizontal blade battery, the suction nozzle A is provided corresponding to the liquid injection port on the horizontal blade battery, so in this embodiment, the two clamping assemblies 10 are arranged to be oppositely arranged in the vertical direction L1, so that the suction nozzle pulling tool 1000 can receive the suction nozzle A in the transverse direction L2, thereby adapting to the position of the suction nozzle A. And under the action of the driving mechanism 20, at least one of the two clamping assemblies 10 can move towards or away from the other in the vertical direction L1, so as to provide or cancel the clamping force for the suction nozzle A in the vertical direction L1, thereby realizing the clamping or releasing of the suction nozzle A in the vertical direction L1. Therefore, during the process of pulling out the suction nozzle, the suction nozzle pulling tool 1000 of the present application not only can adapt to the fixation of the suction nozzle A corresponding to the horizontal blade battery, but also can fix the suction nozzle A by clamping the suction nozzle A through the two clamping assemblies 10, which improves the acting force between the suction nozzle A and the clamping assembly 10, thereby avoiding the problem of the suction nozzle A falling due to too small acting force during the process of pulling out the suction nozzle, thereby improving the stability and pulling efficiency of the suction nozzle during the process of pulling out the suction nozzle, and further being able to replace the suction nozzle A in time.

[0047] Figure 3 A partial structure perspective view of the suction nozzle pulling tool provided by the present application is shown in the figure; Figure 4 A partial structure perspective view of the suction nozzle pulling tool provided by the present application is shown in the figure; Figure 3 An enlarged view of the circled part in the figure; Figure 5 A partial structure perspective view of the suction nozzle pulling tool provided by the present application is shown in the figure.

[0048] Referring to Figure 3 and Figure 4 Each clamping assembly 10 comprises a clamping plate 11 and a plurality of clamping claws 12, which are arranged on the clamping plate 11 in the longitudinal direction L3. Among them, the clamping plates 11 of the two clamping assemblies 10 are arranged opposite in the vertical direction L1, and the clamping claws 12 of the two clamping assemblies 10 are arranged one by one in the vertical direction L1 to clamp or release the corresponding suction nozzle A respectively.

[0049] Among them, the driving mechanism 20 is connected with at least one of the two clamping plates 11, so that the driving mechanism 20 can drive the corresponding clamping plate 11 to act in the vertical direction L1, so that the two clamping claws 12 opposite in the vertical direction L1 can clamp or release the corresponding suction nozzle A.

[0050] It can be understood that the driving mechanism 20 can be connected with one of the clamping plates 11, so that the driving mechanism 20 can drive the clamping plate 11 connected therewith to act in the vertical direction L1, so that the clamping plate 11 moves towards or away from the other clamping plate 11 in the vertical direction L1, thereby enabling the two clamping claws 12 opposite in the vertical direction L1 to clamp or release the corresponding suction nozzle A. Of course, the driving mechanism 20 can be connected with both clamping plates 11 at the same time, so that the driving mechanism 20 can drive both clamping plates 11 to act at the same time, so that the two clamping plates 11 move towards or away from each other in the vertical direction L1, thereby enabling the two clamping claws 12 opposite in the vertical direction L1 to clamp or release the corresponding suction nozzle A.

[0051] In this embodiment, by arranging a plurality of clamping claws 12 on each clamping plate 11, the clamping or release of a plurality of suction nozzles A can be achieved through the relative movement between the two clamping plates 11, thereby improving the pulling efficiency during the pulling of the suction nozzle.

[0052] Referring to Figure 4 Each clamping claw 12 comprises a connecting arm 121, a clamping arm 122, and a plurality of clamping protrusions 123. Among them, the connecting arm 121 is connected with the clamping plate 11 and protrudes from the clamping plate 11 in the transverse direction L2; the clamping arm 122 is arranged at the end of the connecting arm 121 away from the clamping plate 11 and protrudes from the connecting arm 121 in the vertical direction L1, and the connecting arm 121 extends towards the clamping claw 12 opposite in the vertical direction L1; a plurality of clamping protrusions 123 are arranged in the transverse direction L2, and each clamping protrusion 123 protrudes from the clamping arm 122 in the vertical direction L1.

[0053] Since the connecting arm 121 protrudes from the clamping plate 11 in the transverse direction L2, and the clamping arm 122 protrudes from the connecting arm 121 in the vertical direction L1, each clamping jaw 12 is formed as an L-shaped structure, and the clamping jaw 12 in the L-shaped structure can clamp a part of the suction nozzle A (such as one end of the suction nozzle A), so that the suction nozzle A can be smoothly dropped from the clamping jaw 12 after being loosened, thereby achieving clamping and loosening of the suction nozzle A by the clamping jaw 12. At the same time, based on the plurality of clamping protrusions 123 arranged on the clamping arm 122, the clamping jaw 12 can provide multiple clamping forces for the suction nozzle A in the transverse direction L2, thereby improving the clamping stability of the clamping jaw 12 to the suction nozzle A.

[0054] In order to adapt to the shape of the suction nozzle A, the surface of each clamping protrusion 123 in the vertical direction L1 is an arc surface, so that each clamping protrusion 123 can form a surface contact with the suction nozzle A, ensuring that the suction nozzle A and the clamping jaw 12 have sufficient friction, thereby avoiding slipping between the suction nozzle A and the clamping jaw 12 during the process of pulling out the suction nozzle, thereby improving the stability and pulling efficiency during the process of pulling out the suction nozzle.

[0055] Referring to Figure 3 and Figure 5 , each suction nozzle pulling unit 100 further comprises a mounting plate 30 and an elastic member 80, the mounting plate 30 is located between the fixed frame 200 and the clamping plate 11 of the clamping assembly 10 in the transverse direction L2, and the clamping plates 11 of the two clamping assemblies 10 are arranged on the fixed frame 200 through the mounting plate 30, and the elastic member 80 is arranged between the mounting plate 30 and the fixed frame 200.

[0056] Based on the arrangement of the elastic member 80, when the two clamping jaws 12 opposite in the vertical direction L1 clamp a corresponding suction nozzle A, the clamping force of the clamping jaw 12 to the suction nozzle A can be buffered, thereby avoiding damage to the suction nozzle A. At the same time, when the two clamping jaws 12 opposite in the vertical direction L1 loosen the corresponding suction nozzle A, the effect of eliminating the gap can be achieved.

[0057] Continuing to refer to Figure 4 , each suction nozzle pulling unit 100 further comprises a connecting block 40 and an adjusting assembly 50, the connecting block 40 is fixedly arranged on the fixed frame 200, one end of the adjusting assembly 50 is connected with the mounting plate 30, the other end is connected with the connecting block 40, and the adjusting assembly 50 is arranged to be capable of moving relative to the connecting block 40, so as to adjust the relative position of the mounting plate 30 and the fixed frame 200 in the vertical direction L1.

[0058] Since the adjusting assembly 50 can drive the mounting plate 30 and the clamping assembly 10 thereon to move in the vertical direction L1 relative to the fixing frame 200 to adjust the position of the clamping assembly 10 on the fixing frame 200, the relative position adjustment between the two clamping assemblies 10 and the suction nozzle A can be realized, so that the two clamping assemblies 10 can be aligned with the suction nozzle A in the lateral direction L2 to accurately receive the suction nozzle A, thereby avoiding the problem of unstable clamping or even damage to the suction nozzle A caused by the clamping assembly 10 deviating from the suction nozzle A.

[0059] Further, the adjusting assembly 50 includes an adjusting rod 51 and a fastener 52, one end of the adjusting rod 51 is connected with the mounting plate 30, the other end is inserted into the through hole on the connecting block 40, and the fastener 52 locks the adjusting rod 51 and the connecting block 40 after the adjusting rod 51 is moved into position relative to the connecting block 40.

[0060] Specifically, the through hole on the connecting block 40 has a notch in its radial direction, the adjusting rod 51 enters the through hole through the notch, the end of the adjusting rod 51 away from the mounting plate 30 has a stop end portion with an outer diameter greater than the diameter of the through hole, and the fastener 52 cooperates with the stop end portion to clamp the connecting block 40 in the vertical direction L1, thereby fixing the adjusting rod 51 and the connecting block 40.

[0061] Continuing to refer to Figure 4 Each plug-in unit 100 further includes a sliding rail 60 and a sliding block 70, the sliding rail 60 is arranged on the mounting plate 30 and extends in the vertical direction L1, and the sliding block 70 is arranged on each clamping plate 11 and is in sliding connection with the sliding rail 60. That is, the two clamping plates 11 of each plug-in unit 100 are in sliding connection with the same sliding rail 60 through two different sliding blocks 70, thereby realizing the synchronous movement between the two clamping plates 11 to ensure the alignment accuracy of the two opposite clamping jaws 12 in the vertical direction L1, and avoid the problem of unstable clamping or damage to the suction nozzle A caused by the deviation of the two opposite clamping jaws 12 from each other.

[0062] Figure 6 The structure schematic diagram of the driving mechanism of the suction nozzle plug-in unit provided in the present application is shown.

[0063] Referring to Figure 6 In some embodiments, the driving mechanism 20 includes a first rack 21, a gear 23, and a driving unit 24. The first rack 21 is connected with one of the clamping plates 11 and is arranged upright in the vertical direction L1 relative to the gear 23, the gear 23 is in meshing connection with the first rack 21, and the driving unit 24 is connected with the gear 23 and drives the gear 23 to rotate, so that the first rack 21 can move in the vertical direction L1 towards the other clamping plate 11, to realize the relative movement between the two opposite clamping jaws 12 in the vertical direction L1.

[0064] In the driving mechanism 20, the rotational motion of the driving unit 24 can be converted into the linear motion of the first rack 21 through the cooperation between the first rack 21 and the gear 23, so as to realize the relative motion between the two opposing clamping jaws 12 in the vertical direction L1. This driving mode is simple and efficient, and can ensure the pulling efficiency during the pulling of the suction nozzle.

[0065] In other embodiments, the driving mechanism 20 can further include a second rack 22 connected to the other clamping plate 11 and engaged with the gear 23, i.e., the second rack 22 and the first rack 21 are connected to two different clamping plates 11 respectively. Among them, the second rack 22 and the first rack 21 are respectively arranged on the two sides of the gear 23 in the longitudinal direction L3, and can move towards or away from each other in the vertical direction L1 under the action of the rotation of the gear 23, so as to realize the relative motion between the two opposing clamping jaws 12 in the vertical direction L1.

[0066] Through the cooperation between the first rack 21, the second rack 22 and the gear 23, the synchronous action between the second rack 22 and the first rack 21 can be realized, so as to realize the synchronous motion between the two opposing clamping jaws 12 in the vertical direction L1. Not only can it ensure the pulling efficiency during the pulling of the suction nozzle, but also based on the fact that the two clamping jaws 12 can simultaneously provide clamping force in opposite directions to the suction nozzle A, the clamping stability of the suction nozzle A is higher and more conducive to the pulling of the suction nozzle A.

[0067] The driving unit 24 can include a motor 241 and a speed reducer 242, and the motor 241 is connected with the gear 23 through the speed reducer 242, which can improve the transmission efficiency between the motor 241 and the gear 23. At the same time, while ensuring that the suction nozzle A can be pulled out, the clamping force between the two clamping jaws 12 is avoided to be too large to damage the suction nozzle A. The torque feedback mode can be set for the motor 241, or the limit block position can be set on the mounting plate 30 to limit the motion of the sliding block 70.

[0068] Continuing to refer to Figure 1 and Figure 2 , the suction nozzle pulling tool 1000 further includes a bottom plate 300 and an electromagnet 400, and the fixed frame 200 is arranged on one end of the bottom plate 300 in the transverse direction L2, and the electromagnet 400 is arranged on the other end of the bottom plate 300 in the transverse direction L2.

[0069] When the suction nozzle pulling tool 1000 clamps and holds the suction nozzle, and the press mechanism drives the negative pressure cup to move away from the suction nozzle pulling tool 1000 in the transverse direction L2 to pull out the suction nozzle, since the bottom plate 300 will have a tendency to tilt during the pulling of the suction nozzle, the electromagnet 400 provides a abutting force for the bottom plate 300 in the vertical direction L1 at this time, so as to prevent the bottom plate 300 and the clamping assembly 10 thereon from tilting.

[0070] The fixed frame 200 includes a vertical plate 210 and a plurality of support plates 220. The vertical plate 210 is vertically arranged on the bottom plate 300 to mount the plug-pull unit 100. The plurality of support plates 220 are arranged on the bottom plate 300 in a transverse direction L2 and connect the vertical plate 210 and the bottom plate 300. As shown in Figure 5 .

[0071] The plug-pull device 1000 further includes a collection box 500, a power supply box 600, and a photoelectric sensor 700. The collection box 500 is arranged below the two clamping assemblies 10 of the plug-pull unit 100 to collect the mouthpieces A released by the two clamping assemblies 10. The photoelectric sensor 700 is arranged in pairs, and the two photoelectric sensors 700 in each pair are oppositely arranged on the fixed frame 200 in the longitudinal direction L3 to detect whether the mouthpiece A exists in the plug-pull device 1000.

[0072] The number of the collection box 500 can be consistent with the number of the plug-pull unit 100, and each collection box 500 can collect the mouthpieces A released by the two clamping assemblies 10 of the corresponding plug-pull unit 100. Of course, the number of the collection box 500 can be inconsistent with the number of the plug-pull unit 100, and each collection box 500 can collect the mouthpieces A released by a plurality of plug-pull units 100. For example, in the present application, the collection box 500 is arranged as one, and the plug-pull unit 100 is arranged as two. The collection box 500 can simultaneously collect the mouthpieces A released by the two plug-pull units 100.

[0073] The power supply box 600 can be connected to an external power supply or a power supply on the pressing mechanism to supply power to the driving mechanism 20 and other power-consuming mechanisms of the plug-pull unit 100.

[0074] The photoelectric sensor 700 detects whether the mouthpiece A exists in the plug-pull device 1000 through the photoelectric light transmission hole. When the mouthpiece A is not removed, the light source of the photoelectric sensor 700 is blocked, and the signal is transmitted to the control module. When the mouthpiece A is completely removed, the light source of the photoelectric sensor 700 is not blocked, and the signal is also transmitted to the control module, so that the operator can know whether the mouthpiece A is completely removed in time.
